* Fix function_call_output.output to be a JSON string on the wire
OutputConverter was passing the JSON serialization of complex tool results (e.g. List<TodoItem>) directly into OutputItemFunctionToolCallOutput via BinaryData.FromString. The Responses SDK treats that BinaryData as the *raw JSON value* for the field, so non-string results landed on the wire as an unquoted JSON array (e.g. `"output":[{...}]`) instead of a JSON string.
The OpenAI Responses spec requires `function_call_output.output` to be a JSON string. The strict-parsing OpenAI .NET client (FunctionCallOutputResponseItem) consequently failed when threading a follow-up turn that replayed such an item, with: `The JSON value could not be converted... requires an element of type 'String', but the target element has type 'Array'`.
Always wrap the payload as a JSON string literal:
- string s -> JSON-encode s (quoted, with escapes)
- object o -> JSON-serialize o, then JSON-encode the resulting text

* Address PR feedback: JsonElement special-case, symmetric inbound unwrap, tests
OutputConverter: extract EncodeFunctionResultAsJsonStringPayload helper
that special-cases JsonElement / JsonDocument so a string-kind element
does not get double-encoded into "\"value\"". Other JsonElement kinds
(object/array/number/bool) round-trip via GetRawText() and are then
JSON-string-wrapped, matching the spec.
InputConverter: symmetric DecodeFunctionResultPayload added to
ConvertFunctionCallOutput and ConvertFunctionToolCallOutput so
previously-stored function_call_output items replayed via
previous_response_id unwrap back to the original tool result text
instead of leaking the JSON-encoded form into FunctionResultContent.Result.
Legacy non-conforming raw-JSON-value payloads pass through unchanged.
Tests:
- Replace ConvertUpdatesToEventsAsync_FunctionResultStringPayload_EmittedAsRawTextAsync
with EmittedAsJsonStringAsync asserting the new wire contract ("sunny" -> "\"sunny\"").
- Add coverage for object payloads, JsonElement string kind (no double-encoding),
and JsonElement array kind (JSON-stringified).
- Add InputConverter round-trip tests for spec-compliant JSON-string payloads
and legacy raw-JSON-array payloads.
All 663 tests pass on net8/net9/net10. Verified end-to-end against the local
hosted-harness sample: T1-T4 (incl. TodoList tool replay across turns) all
succeed with no SDK parse errors.

- Increase timeout from 120s/90s to 180s to accommodate 2+ LLM round-trips
- Replace rigid 2-cycle assertion with flexible approval logic that handles
extra review cycles from LLM non-determinism
Fixes the two failure modes identified in #4971:

* Increase AzureFunctions LongRunningTools test timeouts from 90s to 180s
The LongRunningToolsSampleValidationAsync test in the AzureFunctions integration
tests was failing in CI with TimeoutException at the 'Content published

environments where LLM calls and orchestration overhead can be slow.
Increased all three WaitForConditionAsync timeouts from 90s to 180s:
- Waiting for human feedback notification
- Waiting for publish notification (the step that was failing)
- Waiting for orchestration completion

* Add RetryFact to DurableTask and AzureFunctions integration tests
These tests interact with LLMs via stdin/stdout (DurableTask) or HTTP
(AzureFunctions) and are inherently non-deterministic. Unlike the Python
side which uses pytest-retry, the dotnet tests had no retry mechanism
and a single transient failure would fail the entire CI run.
Changes:
- Switch [Fact] to [RetryFact(2, 5000)] on all LLM-dependent tests
across ConsoleAppSamplesValidation, ExternalClientTests,
WorkflowConsoleAppSamplesValidation, and AzureFunctions SamplesValidation
- Add re-prompt mechanism to LongRunningToolsSampleValidationAsync:
if the LLM doesn't invoke the tool within 60s, re-send the prompt
(up to 2 retries) instead of burning the full timeout
- Reduce LongRunningTools timeout from 240s to 180s (re-prompt makes
the extra buffer unnecessary)
- Leave simple/deterministic tests as [Fact] (SingleAgent, unit tests)

CI publish step: gate the BuildProjectReferences=false fast-path on an explicit -UsePrebuiltProjectReferences switch (passed by the workflow) instead of marker detection. Adds a preflight error when stale obj/Release/net10.0 outputs would cause CS0579, with actionable recovery instructions.
Telemetry UT flake: AgentFrameworkResponseHandlerTelemetryTests was using a plain List<Activity> for OTel's InMemoryExporter. The exporter writes from background Activity completion callbacks while parallel tests on the same global ActivitySource feed every listener, racing against the assertion's enumeration and throwing 'Collection was modified'. Replaced with a small thread-safe ConcurrentActivityList that locks add/enumerate and returns a snapshot for assertions.
* fix: wrap asyncio.CancelledError in ToolException in _connect_on_owner (#5667)
asyncio.CancelledError is a BaseException (not Exception) in Python 3.8+.
When an MCP server is unreachable, the MCP library's internal anyio task
group raises CancelledError, which escaped all three 'except Exception'
handlers in _connect_on_owner(). This propagated through
_run_lifecycle_owner -> _run_on_lifecycle_owner -> connect -> __aenter__,
bypassing user except Exception blocks entirely.
Fix: change the three except-Exception clauses in _connect_on_owner to
'except (Exception, asyncio.CancelledError)' so spurious CancelledErrors
from the MCP transport layer are caught and wrapped in ToolException,
consistent with the method's documented contract.

* fix(mcp): propagate genuine task CancelledError in connect() (#5667)
On Python >= 3.11, check task.cancelling() > 0 before wrapping
CancelledError as ToolException in the three except blocks inside
_connect_on_owner(). When the current task is being cancelled by its
caller, the CancelledError now propagates after cleanup, consistent
with the existing pattern at _mcp.py:560-564 and _runner.py:115-120.
On Python < 3.11 task.cancelling() is unavailable, so MCP-internal
CancelledErrors still cannot be reliably distinguished from
caller-driven cancellation; they continue to be wrapped as
ToolException with a comment documenting the trade-off.
Tests:
- Add cleanup assertion to transport-creation CancelledError test
- Add MCPStdioTool variants exercising the 'command' message branches
for both transport-creation and initialize CancelledError paths
- Add Python 3.11+-gated tests verifying genuine task cancellation
propagates (and still cleans up) for transport and initialize stages

* fix(mcp): log CancelledError with exc_info before wrapping in ToolException (#5667)
CancelledError inherits from BaseException (not Exception) on Python >= 3.8,
so the 'inner_exception=ex if isinstance(ex, Exception) else None' guard
always yields None for CancelledError. This means ToolException.__init__
calls logger.log(level, message, exc_info=None), dropping the traceback.
Add an explicit logger.debug(error_msg, exc_info=ex) before each
raise ToolException(...) in the three CancelledError handlers so the
full traceback is preserved in debug logs when MCP-internal cancellation
is wrapped rather than propagated.

* refactor: factor out _close_and_check_cancelled helper in _connect_on_owner
Addresses review comment on PR #5687:
1. Add _close_and_check_cancelled() helper method that combines
_safe_close_exit_stack() + _should_propagate_cancelled_error() into a
single await-able call. This eliminates the duplicated close-then-check
pattern that appeared identically in all three connect phases (transport,
session, initialize), reducing future drift risk.
2. Comments 2 and 3 (missing {ex} in session error message and non-idiomatic
exc_info=ex) were already addressed in the current code: all error messages
include {ex} and all logger.debug calls use exc_info=True.
3. Add test_connect_genuine_cancellation_during_session_creation_propagates
to cover the previously untested genuine-cancellation path in the
session-creation phase (transport and initialize phases already had tests).

When the operating mode is changed externally (e.g. via a slash-command handler
calling set_agent_mode), the agent's chat history still shows the prior set_mode
tool call near the end. Updating only the system instructions is insufficient —
models tend to anchor on the recent tool call and ignore the new mode.
Mirror the .NET AgentModeProvider behavior: when set_agent_mode detects an actual
mode change, record the previous mode in provider state. On the next before_run,
the provider pops that flag and injects a user-role notification message
announcing the switch, so the most recent context unambiguously reflects the
current mode. The agent-driven set_mode tool path bypasses this so it does not
trigger a redundant notification on its own change.

* Fix dangling function_call on approval response in Foundry hosting (#5662)
Make the wire<->AF approval translation in Microsoft.Agents.AI.Foundry.Hosting lossless so the resume turn pairs function_call/function_call_output correctly.
Root cause: InputConverter.ConvertMcpApprovalResponse rebuilt FunctionCallContent with CallId set to the FICC-composed AF request id (ficc_<callId>) and Name hardcoded to 'mcp_approval'. This (a) broke Azure Conversations pairing because the persisted function_call had CallId <callId> without prefix, and (b) made FICC unable to invoke the original tool by name on resume.
Fix: ToolApprovalIdMap now records the original FunctionCallContent (CallId, Name, Arguments) keyed by wire id at outbound time. InputConverter reconstructs the original FCC on inbound, falling back to the legacy placeholder when no mapping exists.
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* Suppress orphan function_call items at the wire (#5662)
Foundry-Hosting's OutputConverter was emitting FunctionCallContent as wire `function_call` items while dropping the paired FunctionResultContent. The result: every auto-invoked tool call left an orphan `function_call` in the response store. The next turn (chained via previous_response_id or via a workflow that yields after one turn under externalLoop) reloaded that history and submitted it to Azure Conversations, which rejected it with HTTP 400 `No tool output found for function call ...`.
Function call/result pairs are entirely internal to the agent's tool-calling loop and have no place on the wire. Approval-required calls already surface separately via ToolApprovalRequestContent → mcp_approval_request, so dropping FCC is safe.
FCC's message-close behavior is preserved so pre-tool text doesn't accidentally concatenate with post-tool text under the same MessageId. Existing OutputConverter tests asserting FCC wire emission are updated to assert suppression.
Verified end-to-end against the declarative-workflow-menu external_loop bench: three-turn previous_response_id chain (menu → carbonara price → EXIT) now completes, where it previously failed at turn 2 with HTTP 400.

* Fail fast when no approval mapping is recorded (#5662)
The previous best-effort placeholder fallback in InputConverter.ConvertMcpApprovalResponse couldn't actually round-trip — it just delayed and obscured the failure as an HTTP 400 deep inside the agent loop. Throw InvalidOperationException with the wire id and a clear cause hint instead so the failure is local and actionable.

Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* Defer FunctionCallContent emission until matched FunctionResultContent (#5662)
Replace blanket FCC suppression with deferred emission. FunctionCallContent
is buffered (name + serialized arguments) keyed by CallId; the function_call
and function_call_output wire items are only flushed once the matching
FunctionResultContent arrives.
- Auto-invoked FCC/FRC pairs surface as paired wire items so Azure's stored
conversation has matched call+output and previous_response_id resume
works (closes the orphan-function_call symptom from #5662).
- Orphan FCCs (e.g. workflow paused at a checkpoint mid-tool-loop) are
dropped so they never poison the response store.
- Approval flows are unchanged: TARC still emits mcp_approval_request and
the post-approval FRC has no buffered FCC to pair with so it is dropped;
the approval round-trip handles its own pairing via mcp_approval_*.
- Leaves the door open for future client-side function calling: that
pattern would surface an FCC without an FRC, would need to opt out of
buffering, but the wire shape is already correct.
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* Emit FunctionCallContent and FunctionResultContent directly (option B)
Replace the deferred-emission/buffer-and-drop strategy with direct emission of both function_call and function_call_output wire items.
Rationale: a lone FunctionCallContent in OutputConverter's input can mean two semantically different things, and only the caller knows which:
- Auto-invoke (FICC response surface): always paired with a matching FRC; both halves should appear on the wire as historical record.
- HITL / port-pause request (typed RequestPort<FunctionCallContent,...> or workflow synthesizing a request): a lone FCC IS the wire signal that the caller must resume by supplying a function_call_output.
Buffering+dropping orphans silently swallows the second case. Emitting both directly is the only correct shape for OpenAI Responses semantics.
The InputConverter already accepts function_call_output and mcp_approval_response on resume, so the round-trip works for both kinds.
The approval-flow round-trip fixes (ToolApprovalIdMap rich ApprovalEntry, fail-fast on missing mapping in ConvertMcpApprovalResponse) remain intact.
Tests: updated 7 OutputConverter tests + 1 OutputConverterWorkflow test that asserted the old buffer/drop semantics; all 227 tests pass.

The catch block recovered to an empty map and a stale comment claimed the caller would gracefully degrade via a 'wire-id fallback path' — but that path no longer exists: InputConverter.ConvertMcpApprovalResponse fails fast when no entry is found.
Letting the JsonException propagate produces an error message that points at the actual cause (a state-bag format incompatibility), instead of converting it into a confusing 'no approval mapping recorded' InvalidOperationException one stack frame later.

* Address PR #5668 review feedback round 2
- OutputConverter FRC: emit string results as raw text (no JSON-quoting),
matching the wire contract for function_call_output.output.
- OutputConverter FCC: validate non-empty CallId before closing the in-flight
text message, so a skipped FCC no longer breaks output-item boundaries.
- ToolApprovalIdMap.Record: take pre-serialized arguments JSON (string) and
primitive callId/name. Drops [RequiresUnreferencedCode]/[RequiresDynamicCode]
so trim/AOT warnings stop propagating to call sites.
- ToolApprovalIdMap.Record: no-op when callId or name is empty.
- Tests: dedup duplicate ConvertItemsToMessages_McpApprovalResponse no-mapping
test; add coverage for empty-CallId boundary, raw-string FRC payload, and
Record empty-key no-op.

* Remove Foundry toolbox helpers; standardize on MCP for toolbox consumption
- Remove RawFoundryChatClient.get_toolbox() and its fetch_toolbox import
- Remove fetch_toolbox, select_toolbox_tools, get_toolbox_tool_name,
get_toolbox_tool_type, FoundryHostedToolType, ToolboxToolSelectionInput
from agent_framework_foundry._tools
- Remove ExperimentalFeature.TOOLBOXES from _feature_stage.py (no consumers)
- Drop toolbox re-exports from agent_framework_foundry/__init__.py and
agent_framework.foundry namespace
- Update _sanitize_foundry_response_tool docstring to remove toolbox framing;
sanitization logic itself is unchanged
- Update _agent.py docstring: 'toolbox-fetched MCP' → 'hosted MCP'
- Delete tests/test_toolbox.py (all tests covered removed helpers)
- Update test_foundry_chat_client.py: rename/redoc tests that mentioned
toolbox but test sanitization that remains
- Delete foundry_chat_client_with_toolbox.py (bespoke toolbox API sample)
- Delete foundry_toolbox_context_provider.py (relied on select_toolbox_tools)
- Rename foundry_chat_client_with_toolbox_mcp.py →
foundry_chat_client_with_toolbox.py (canonical MCP pattern)
- Rewrite 04_foundry_toolbox/main.py to use MCPStreamableHTTPTool
- Update provider/README, context_providers/README, 04_foundry_toolbox/README

* fix(samples): update 06_files sample to consume toolbox via MCP (#5670)
Replace removed get_toolbox/select_toolbox_tools APIs with
MCPStreamableHTTPTool, using allowed_tools=["code_interpreter"] to
select only the code interpreter from the toolbox endpoint.
Update .env.example and README to use FOUNDRY_TOOLBOX_ENDPOINT
instead of TOOLBOX_NAME.

* fix(foundry): remove non-existent toolbox helper APIs from README (#5670)
Remove the 'fetch, optionally filter, and pass tools directly' pattern
from the FoundryChatClient toolbox documentation, as select_toolbox_tools
and get_toolbox were removed. Only the MCP endpoint pattern is documented.

* fix(foundry): remove residual toolbox docstring references and reproduction report
Remove REPRODUCTION_REPORT.md (workflow artifact that should not be committed),
and update two remaining docstring references that still said 'toolbox reads'
/'toolbox definition' after the toolbox helpers were removed.

* Python: Remove bespoke Foundry toolbox helpers; standardize on MCP for toolbox consumption
Fixes#5670
* fix(#5670): resolve toolbox endpoint from TOOLBOX_NAME fallback; add namespace regression tests
- Add _resolve_toolbox_endpoint() helper in 04_foundry_toolbox/main.py and
06_files/main.py that prefers FOUNDRY_TOOLBOX_ENDPOINT but falls back to
deriving the MCP URL from FOUNDRY_PROJECT_ENDPOINT + TOOLBOX_NAME — fixing
the startup KeyError when agents are deployed via azd provision (which injects
TOOLBOX_NAME, not FOUNDRY_TOOLBOX_ENDPOINT).
- Update 04_foundry_toolbox/.env.example to use FOUNDRY_TOOLBOX_ENDPOINT
(consistent with 06_files).
- Add TOOLBOX_NAME env var to 06_files/agent.yaml so deployed agents have it
available for the fallback derivation.
- Update both READMEs to document the two ways to supply the toolbox endpoint.
- Add test_foundry_namespace_no_longer_exposes_toolbox_helpers() with negative
assertions for FoundryHostedToolType, get_toolbox_tool_name,
get_toolbox_tool_type, and select_toolbox_tools — guarding against accidental
re-introduction of removed symbols.

* fix(samples): fail fast on empty FOUNDRY_TOOLBOX_ENDPOINT; add unit tests
Addresses review feedback for #5670:
- In _resolve_toolbox_endpoint() (04_foundry_toolbox/main.py and
06_files/main.py) change the walrus-operator check from a truthy
test to an explicit 'is not None' guard. An explicitly set empty
string now raises ValueError immediately with a clear message
instead of silently falling through to the fallback URL
construction.
- Add tests/samples/hosting/test_toolbox_endpoint.py covering both
sample modules:
(a) FOUNDRY_TOOLBOX_ENDPOINT set → returned as-is
(b) FOUNDRY_TOOLBOX_ENDPOINT set to empty string → ValueError
(c) fallback constructs URL from FOUNDRY_PROJECT_ENDPOINT + TOOLBOX_NAME,
stripping trailing slashes
(d) neither variable group set → KeyError

* Address review feedback: remove extraneous test and docstring content
- Remove test_foundry_namespace_no_longer_exposes_toolbox_helpers (no longer warranted)
- Remove docstring from _agent.py _prepare_tools_for_openai (extraneous)
- Trim _chat_client.py _prepare_tools_for_openai docstring to one-liner (toolbox references no longer relevant)
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* fix: remove remaining extraneous docstring from RawFoundryChatClient._prepare_tools_for_openai
Address review comment on PR #5671: reviewer noted the description
isn't warranted now that toolbox helpers have been removed. Matches
the pattern in RawFoundryAgentChatClient which has no docstring.

* Foundry.Hosting.IntegrationTests: scaffold project, fixtures, and 24 tests
Add a new integration test project for Foundry hosted agents alongside the existing Foundry.IntegrationTests project. The project provisions a real Foundry hosted agent per scenario via AgentAdministrationClient.CreateAgentVersionAsync, points it at a single test container image (built and pushed out of band by scripts/it-build-image.ps1 in a follow up commit), and exercises the agent through AIProjectClient.AsAIAgent.
Six scenario fixtures are introduced, each pointing at the same image but selecting behavior via the IT_SCENARIO environment variable on the HostedAgentDefinition:
- HappyPathHostedAgentFixture (round trip, multi turn, stored=false flag)
- ToolCallingHostedAgentFixture (server side AIFunctions)
- ToolCallingApprovalHostedAgentFixture (approval flow)
- ToolboxHostedAgentFixture (Foundry toolbox)
- McpToolboxHostedAgentFixture (MCP backed toolbox)
- CustomStorageHostedAgentFixture (custom storage provider)
24 tests across 6 test classes are scaffolded. All are tagged Skip pending the test container build and the end to end smoke iteration in follow up commits. Once the container is in place the Skip annotations can be removed scenario by scenario.
Adds an IT_HOSTED_AGENT_IMAGE constant to the shared TestSettings so every IT project agrees on the env var name the build script emits.
* Foundry.Hosting.IntegrationTests: add TestContainer, build script, slnx, README
Adds the rest of the integration test infrastructure on top of the previous scaffolding commit:
* Foundry.Hosting.IntegrationTests.TestContainer csproj and Program.cs implementing the multi scenario container (one image, IT_SCENARIO env var dispatches between happy-path, tool-calling, tool-calling-approval, toolbox, mcp-toolbox, and custom-storage). The toolbox, mcp-toolbox, and custom-storage branches are placeholders pending API surface stabilization.
* Dockerfile and dockerignore in the test container project, using the contributor pattern matching the investigation work (host side dotnet publish, container only does COPY out/).
* scripts/it-build-image.ps1 with mandatory Registry parameter (no hardcoded ACR), content hashed tags so unchanged source results in a no op push, and emits IT_HOSTED_AGENT_IMAGE for shells and CI to consume.
* slnx entry for both new projects.
* README in the IT project covering env vars, image build, scenario table, and current placeholder status.
Steps still pending: end to end smoke (step 5) and CI workflow integration (step 6) require a live Foundry deployment and ACR push, so they land in follow up commits.
* Foundry.Hosting.IntegrationTests: address PR 5598 review feedback
Fix issues raised by Copilot review:
* it-build-image.ps1: hash file contents, not the path list, so any source edit produces a fresh tag. Normalize Registry input by stripping scheme and trailing slash before deriving the ACR short name. Validate the short name is non empty.
* HostedAgentFixture: route GetAgentAsync through _adminClient (which has the FoundryFeaturesPolicy attached) instead of through _projectClient.AgentAdministrationClient (which does not).
* HostedAgentFixture FoundryFeaturesPolicy: replace Headers.Add with Remove plus Add so retries cannot accumulate duplicate headers.
* HappyPath, ToolCalling, ToolCallingApproval, CustomStorage tests: create the AgentSession before turn 1 and reuse it for both turns. The previous pattern created the session after turn 1 so turn 2 had no link to turn 1, defeating the multi turn assertion.
* .NET: Foundry.Hosting.IntegrationTests: constrain to net10.0 + dotnet format autofix
- Set <TargetFrameworks>net10.0</TargetFrameworks>: the project references both
Microsoft.Agents.AI.Foundry.Hosting (net8/9/10 only) and AgentConformance.IntegrationTests
(net10.0;net472 — inherits the tests-default TFM list). The intersection is net10.0;
the previous $(TargetFrameworksCore) triple caused NU1702 + System.Text.Json version
conflicts on the net8.0/net9.0 builds because AgentConformance had no matching asset.
- Apply `dotnet format` autofix on the test files (IDE0005, IDE0009, IDE0032, IMPORTS).
* .NET: Foundry.Hosting.IntegrationTests.TestContainer/Program.cs: add UTF-8 BOM
CI's check-format requires charset=utf-8-bom per .editorconfig.
* Foundry.Hosting IntegrationTests: wire end-to-end CI flow against hosted agents
Make the integration tests usable end-to-end against a live Foundry deployment, including
a per-run rebuild of the test container so framework code changes are exercised.
Fixture (HostedAgentFixture.cs)
* Switch from per-run unique agent names to stable scenario-keyed names (it-happy-path,
it-tool-calling, ...). The agent's managed identity carries the Azure AI User role on
the project scope, which is required for inbound inference; deleting the agent recycles
the MI and breaks that role assignment, so we keep the agent across runs and only churn
versions.
* Add IT_RUN_ID env var to defeat Foundry's content-addressed version dedup; otherwise a
rerun just receives the existing version and Dispose deletes it.
* PATCH the per-agent endpoint with AgentEndpointConfig (Responses protocol, version
selector at 100% to the new version). Without this, /agents/{name}/endpoint/protocols/
openai/responses returns HTTP 400.
* Build a per-agent ProjectOpenAIClient (not the cached projectClient.ProjectOpenAIClient,
which is bound to the project-level URL); set AgentName in options so the URL routes
through the agent endpoint, and add the Foundry-Features header to the inference
pipeline.
* Use Versions (which serializes to container_protocol_versions) instead of the
deprecated ProtocolVersions; the server now rejects the legacy field.
* On Dispose, delete only the version this fixture created. Never delete the agent.
Tests
* Tag every HostedAgentTests class with [Trait("Category", "FoundryHostedAgents")] so the
CI workflow can route them to a separate Foundry project than the rest of the
integration suite.
CI workflow (.github/workflows/dotnet-build-and-test.yml)
* Add a foundryHosting paths-filter covering Microsoft.Agents.AI.Foundry.Hosting and its
in-repo dependency chain (Foundry, Agents.AI, Agents.AI.Abstractions), the test
container, the test fixture, Directory.Packages.props, the build script, and this
workflow file. Skip the costly hosted-agent steps when none of those changed.
* Add "Build and push Foundry Hosted Agents test container" step that invokes
scripts/it-build-image.ps1 against vars.IT_HOSTED_AGENT_REGISTRY and pipes the resulting
IT_HOSTED_AGENT_IMAGE=<tag> into GITHUB_ENV.
* Add "Run Foundry Hosted Agents Integration Tests" step that filters in only the new
trait, with AZURE_AI_PROJECT_ENDPOINT/AZURE_AI_MODEL_DEPLOYMENT_NAME pointed at
IT_HOSTED_AGENT_PROJECT_ENDPOINT/IT_HOSTED_AGENT_MODEL_DEPLOYMENT_NAME (Tao project,
East US 2; the SK IT project's region does not yet support hosted agents preview).
* Exclude the new trait from the existing "Run Integration Tests" step.
* TEMP: drop the != 'pull_request' guard on the new steps and on Azure CLI Login when the
paths-filter triggers, so PR #5598 can validate the wiring before promoting to merge
queue only. Restore the original guard after one green PR run.
Build script (scripts/it-build-image.ps1)
* Hash now spans TestContainer source AND its referenced framework projects so any
framework code change forces a fresh tag and a real docker push; the previous
TestContainer-only hash silently reused stale images on framework edits.
Bootstrap script (dotnet/tests/Foundry.Hosting.IntegrationTests/scripts/it-bootstrap-agents.ps1)
* New idempotent script that creates the six stable scenario agents and grants Azure AI
User on the project scope to each agent's MI. Run once per Foundry project. Includes
AAD-graph propagation retries because newly created MIs take time to appear there.
README (dotnet/tests/Foundry.Hosting.IntegrationTests/README.md)
* Document the bootstrap prerequisite, the regional caveat (East US 2 is the only region
we have validated; East US returned "Unsupported region" at the time of writing), the
per-run image rebuild, and the CI wiring including the SP RBAC requirements.
SDK pin (TEMP)
* Bump Microsoft.Agents.AI.Foundry.Hosting's Azure.AI.Projects VersionOverride to
2.1.0-alpha.20260505.1 from the azure-sdk public daily feed (added to nuget.config).
This release is the first that builds the per-agent inference URL as
/agents/{name}/endpoint/protocols/openai (the 2.1.0-beta.1 release builds
.../openai/openai/v1, which the server rejects). Revert both the feed and the override
once the URL fix lands in a stable Azure.AI.Projects release.
* Foundry.Hosting IntegrationTests: revert alpha SDK pin; move endpoint PATCH to bootstrap
The alpha SDK pin (Azure.AI.Projects 2.1.0-alpha.20260505.1 from the azure-sdk public
daily feed) was needed only for the URL routing fix and the strongly-typed
AgentEndpointConfig/PatchAgentOptions wrapper. We do not need either right now: the
fixture stays compatible with the public 2.1.0-beta.1 by moving the one-time endpoint
PATCH to the bootstrap script (it sets version_selector to FixedRatio @latest, so each
new fixture run becomes the served version automatically without a per-run PATCH from
the test code). The hosted-agent invocation path will start working end-to-end once the
URL routing fix lands in a stable Azure.AI.Projects release; until then the tests stay
[Fact(Skip = ...)] as documented.
* Revert dotnet/nuget.config: drop the azure-sdk-for-net public feed.
* Revert Microsoft.Agents.AI.Foundry.Hosting.csproj VersionOverride to 2.1.0-beta.1.
* Revert Microsoft.Agents.AI.Foundry.UnitTests and Microsoft.Agents.AI.Foundry.Hosting.UnitTests
Azure.AI.Projects pin (they had been bumped to align Azure.Core 1.54 transitive).
* Drop the AgentEndpointConfig PATCH block from HostedAgentFixture.cs (the type is
alpha-only). Replace with a comment pointing at the bootstrap script.
* Bootstrap script (it-bootstrap-agents.ps1) now also PATCHes each agent's endpoint
with version_selector=@latest if not already set. Idempotent.
* Foundry.Hosting IntegrationTests: drop accidentally committed filtered.slnx
* Foundry.Hosting IntegrationTests: revert TEMP PR override on Azure CLI Login + IT steps
The previous attempt to validate the new hosted-agent IT wiring on PR #5598 failed
because the PR is from a fork (rogerbarreto/agent-framework-public). GitHub never passes
environment secrets to fork PRs regardless of event-name guards on individual steps,
so 'azure/login@v2' fails with 'client-id and tenant-id are not supplied'. Restore the
original github.event_name != 'pull_request' guard. The new steps will execute on
push to main and on merge_group runs.
* Foundry.Hosting IntegrationTests: invoke build-and-push script with absolute path
The pwsh shell on the GitHub Actions runner couldn't resolve ./scripts/it-build-image.ps1
when the step had no working-directory set; the step inherits the runner's PWD which is
not always the repo root after preceding steps. Use github.workspace explicitly to remove
the ambiguity.
* Foundry.Hosting IntegrationTests: move it-build-image.ps1 inside the IT project tree
The previous location at scripts/it-build-image.ps1 lived outside the sparse-checkout
paths the workflow uses (.github, dotnet, python, declarative-agents), so the runner
never had the file when the new step tried to invoke it. Move the script next to its
sibling it-bootstrap-agents.ps1 inside the IT project tree, and anchor its relative
paths to the repo root via so callers can invoke it from any PWD.
* Move scripts/it-build-image.ps1 -> dotnet/tests/Foundry.Hosting.IntegrationTests/scripts/it-build-image.ps1
* Add Push-Location to the resolved repo root inside the script (Pop-Location in finally)
so the existing relative paths (TestContainerProject, hashed src dirs) keep working
no matter where the script is invoked from.
* Update the workflow path filter and the step's invocation path to the new location.
* Foundry.Hosting IntegrationTests: enable 5 HappyPath tests on the live Foundry endpoint
The fixture already constructs ProjectOpenAIClient via the per-agent path that beta.1
supports (new ProjectOpenAIClient(uri, cred, opts { AgentName })), so no SDK pin bump
is required to run the smoke tests end-to-end. Un-skip the 5 tests that pass against
the live test container.
Tests un-skipped (verified passing locally against tao-foundry-prj):
* RunAsync_ReturnsNonEmptyTextAsync
* RunStreamingAsync_YieldsAtLeastOneUpdateAsync
* MultiTurn_WithPreviousResponseId_PreservesContextAsync
* StoredFalse_Baseline_DoesNotPersistResponseAsync
* Instructions_FromContainerDefinition_AreObeyedAsync
Tests still skipped with a more specific reason (4 of 9 in HappyPath plus all
ToolCalling*, McpToolbox, Toolbox, CustomStorage) because the test container does not
yet emit usable response_id / conversation_id chains, and the placeholder scenarios are
not implemented in the test container's Program.cs. These are test container limitations,
not infra bugs, and can be un-skipped as the container surfaces stabilize.
* Foundry.Hosting IntegrationTests: extract hosted IT into parallel job, add Workflows dep
Address Wesley's review feedback on PR #5598:
1. Pull Foundry hosted-agent IT into its own dotnet-foundry-hosted-it job that runs in parallel to dotnet-build and dotnet-test. Same path-filter gate keeps it skipped on unrelated edits. Builds only the filtered solution containing Foundry.Hosting.IntegrationTests and src deps. dotnet-build-and-test-check now waits on it too.
2. Add Microsoft.Agents.AI.Workflows to the foundryHosting paths-filter and to hashedDirs in it-build-image.ps1 since Foundry.Hosting transitively depends on it.
TFM constraint on the IT csproj stays at net10.0 because AgentConformance.IntegrationTests targets net10/net472 and is consumed by ~12 other IT projects on net472.

* Bump MEAI to 10.5.1 and add per-call x-client header support
Replaces the brittle UserAgentResponsesClient subclass with a clean
per-call x-client-* header pipeline built on the new Microsoft.Extensions.AI
10.5.1 OpenAIRequestPolicies hook.
Public surface (Microsoft.Agents.AI.Foundry, [Experimental(MAAI001)]):
* chatOptions.WithClientHeader(name, value) and .WithClientHeaders(IEnumerable)
validate the x-client- prefix (case-insensitive), apply all-or-nothing on
bulk, and throw InvalidOperationException on foreign-typed slot collision
* myAgent.AsBuilder().UseClientHeaders().Build() opts a customer-built agent
into the pipeline; idempotent via agent.GetService<ClientHeadersAgent>()
* Foundry-built agents (FoundryAgent.Create*) pre-wire automatically
Internals:
* ClientHeadersAgent decorator snapshots the dict at scope-push time so
concurrent runs sharing a ChatOptions reference do not leak headers
* ClientHeadersScope is an AsyncLocal<IReadOnlyDictionary<string,string>?>
with LIFO push/dispose semantics
* ClientHeadersPolicy singleton stamps headers via Headers.Set so per-call
values overwrite any same-name header from earlier policies and so
duplicate registration is value-stable
* OpenAIRequestPoliciesReflection dedups against MEAI's private _entries
field and falls back to AddPolicy on any reflection failure; a CI test
asserts the field shape on every MEAI bump
Hosting cleanup:
* Deleted UserAgentResponsesClient and its dummy throwing pipeline
* HostedAgentUserAgentPolicy is now registered via OpenAIRequestPolicies
in FoundryHostingExtensions.TryApplyUserAgent
Tests:
* 19 new unit tests in ClientHeadersExtensionsTests.cs covering validation,
AsyncLocal isolation, snapshot semantics, end-to-end wire stamping, and
shared-chat-client dedup
* Updated OpenTelemetryAgentTests for MEAI 10.5.1 changes to web_search
serialization and the reduced tool definition payload when sensitive
data capture is disabled
Microsoft.Extensions.Compliance.Abstractions stays at 10.5.0 because no
10.5.1 release exists on nuget.org.
* Address PR review: pre-wire AsAIAgent path and dedup TryApplyUserAgent
* FoundryAgent: extract WireClientHeaders helper and call it from the
internal (AIProjectClient, ChatClientAgent) constructor used by
AzureAIProjectChatClientExtensions.AsAIAgent so those Foundry-built
agents also pre-wire the x-client header pipeline.
* Foundry.Hosting TryApplyUserAgent: dedup HostedAgentUserAgentPolicy
registration per OpenAIRequestPolicies instance via
ConditionalWeakTable so per-request resolution does not grow the
policy list unboundedly on singleton agents.
* Add tests covering AsAIAgent pre-wire and TryApplyUserAgent dedup
Backs the PR review fixes from a4c8f91 with regression tests:
* ClientHeadersExtensionsTests: AsAIAgent_FoundryAgent_HasPreWiredClientHeadersAgent
asserts the FoundryAgent built via AzureAIProjectChatClientExtensions.AsAIAgent
contains a ClientHeadersAgent in its delegating chain (catches future
regressions of the bypass).
* ClientHeadersExtensionsTests: FoundryAgent_PublicConstructor_HasPreWiredClientHeadersAgent
covers the public constructor path the same way.
* ClientHeadersExtensionsTests: UseClientHeaders_RepeatedRegistrations_OnSameChatClient_OnlyRegistersOnce
invokes UseClientHeaders 25 times on a shared chat client and asserts via
reflection that OpenAIRequestPolicies._entries length is exactly 1.
* HostedTryApplyUserAgentDedupTests: two tests asserting
FoundryHostingExtensions.TryApplyUserAgent stays at one entry per
OpenAIRequestPolicies instance after 50 calls on the same agent and across
distinct agents on different chat clients.
* Move tests next to their SUT
Removes the dedicated HostedTryApplyUserAgentDedupTests.cs test class.
Tests are co-located with the SUT they exercise:
* FoundryAgentTests.cs gains the Constructor_PreWiresClientHeadersAgent
and Constructor_FromAsAIAgentExtension_PreWiresClientHeadersAgent
cases, since FoundryAgent is the SUT for the pre-wire behavior.
* HostedOutboundUserAgentTests.cs gains the two TryApplyUserAgent dedup
cases, since FoundryHostingExtensions.TryApplyUserAgent is the SUT
it already covers.
* ClientHeadersExtensionsTests.cs keeps only the
UseClientHeaders_RepeatedRegistrations_OnSameChatClient_OnlyRegistersOnce
case, which exercises the public ClientHeadersExtensions surface.
* Remove redundant WithCancellation on inner streaming call
ct is already passed to InnerAgent.RunStreamingAsync, so
.WithCancellation(ct) on the resulting IAsyncEnumerable is a no-op.
Caught by Sergey on PR review.
* Address PR review: surface downstream MEAI experimental ID
* Add AIOpenAIRequestPolicies = MEAIExperiments alias to
DiagnosticIds.Experiments (matches the existing AIResponseContinuations,
AIMcpServers, AIFunctionApprovals pattern).
* Mark public ClientHeadersExtensions with [Experimental(AIOpenAIRequestPolicies)]
instead of AgentsAIExperiments. Consumers now see the MEAI001 warning,
surfacing the dependency on MEAI's experimental OpenAIRequestPolicies hook.
* Mark internal OpenAIRequestPoliciesReflection with the same alias to
suppress warnings at the source rather than via project-wide NoWarn.
* Remove MEAI001 from Foundry csproj NoWarn (kept on Foundry.Hosting where
pre-PR usages remain).
* Clarify ClientHeadersScope XML doc: AsyncLocal flows values forward but
does NOT auto-restore on method return; explicit using/Dispose is what
gives stack-style LIFO semantics.
* migrate skills to multi source architecture
* Fix ruff lint errors in skills module (ASYNC240, SIM108, E501)
- Use anyio.Path for async file I/O in _FileSkillResource.read()
- Use noqa: ASYNC240 for pure string os.path calls in async context
- Restore pre-commit if/else pattern in InlineSkillScript.run()
- Break long lines to fit 120-char limit in _skills.py and test_skills.py

* fix: collapse multi-line lambdas to single lines to fix pyright errors
The pyright ignore comments only suppress errors on the same line, so
multi-line lambdas left arguments on continuation lines uncovered.
Collapse both lambdas to single lines matching the existing load_skill
lambda pattern.
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* fix: replace untyped lambdas with typed inner functions to fix pyright errors
Python lambdas cannot have type annotations, so pyright reports
reportUnknownLambdaType and reportUnknownArgumentType errors that
cannot be suppressed with inline ignore comments. Replace the
lambdas for read_skill_resource and run_skill_script with typed
inner async functions.

Also fix pyright errors in tests by adding isinstance assertions
before accessing .function on SkillResource/SkillScript base types.

* refactor: add read-time resource path validation in _FileSkillsSource
Move security validation (path-traversal and symlink guards) for
file-based skill resources into _FileSkillsSource, restoring the
read-time checks that existed in main via _read_file_skill_resource.
- Add _get_validated_resource_path static method on _FileSkillsSource
that validates containment, existence, and symlink safety
- _FileSkillsSource.get_skills() validates resource paths at discovery
time via _get_validated_resource_path before passing to _FileSkillResource
- Move _normalize_resource_path, _is_path_within_directory, and
_has_symlink_in_path from module-level into _FileSkillsSource as
static methods (only used there)
- _FileSkillResource remains a simple path-to-content reader
- Add tests for _get_validated_resource_path security checks

* refactor: move name/description from abstract properties to Skill.__init__
Replace abstract properties for name and description on the Skill ABC
with a base __init__ that validates and stores them as regular
attributes. This simplifies custom Skill subclasses (only content
remains abstract) and centralizes validation in the base class,
consistent with SkillResource and SkillScript base classes.

* .Net: Add hosted agent observability sample
Mirrors the Python sample added in #5608 for Foundry hosted agents. The
.NET hosting library already wires OpenTelemetry automatically via
Microsoft.Agents.AI.Foundry.Hosting (ApplyOpenTelemetry) plus
Azure.AI.AgentServer.Core's AddAgentHostTelemetry, so no framework
changes are needed. The sample is documentation plus a runnable artifact
that produces an interesting span tree (invoke_agent / agent_invoke /
chat / execute_tool).
Adds Hosted-Observability under FoundryHostedAgents/responses with two
small tools (GetCurrentLocation, GetWeather), agent.yaml /
agent.manifest.yaml declaring OTEL_INSTRUMENTATION_GENAI_CAPTURE_MESSAGE_CONTENT
(the .NET equivalent of Python's ENABLE_SENSITIVE_DATA), Dockerfile +
Dockerfile.contributor, .env.example and README explaining the .NET vs
Python defaults. Project added to agent-framework-dotnet.slnx.

* fix(bedrock): don't send toolChoice when no tools are configured
BedrockChatClient was sending toolConfig.toolChoice even when no tools
were configured (tools=None). AWS Bedrock requires toolConfig.tools to
be present whenever toolChoice is specified, causing a 400 validation
error.
Only set toolChoice when tool_config has a 'tools' key present.
Fixes#5165

* test: add tests for toolChoice without tools
- test_prepare_options_tool_choice_auto_without_tools_omits_tool_config
- test_prepare_options_tool_choice_required_without_tools_omits_tool_config
Verifies that toolConfig is omitted when tool_choice is set but no
tools are provided, preventing ParamValidationError from Bedrock.
* fix: address maintainer feedback — remove stray test file, raise ValueError for required without tools
1. Remove test_addition.py — stray duplicate of tests already in
python/packages/bedrock/tests/test_bedrock_client.py, missing all
necessary imports and would fail with NameError.
2. Change tool_choice='required' handling to raise ValueError when no
tools are configured instead of silently falling through. Using
'required' without tools is a logical contradiction — the model
must invoke a tool but none exist — so surfacing this as a
ValueError helps callers catch the misconfiguration early.
3. Update the corresponding test to expect ValueError instead of
silently omitted toolConfig.

When MultiPartyConversation gets saved during checkpointing, the data for the chat history is not persisted, resulting in failures to deserialize after. The fix is to make the history visible to the source generated serialization code.
* Add Microsoft.Agents.AI.Hyperlight package for CodeAct integration
Introduces a new Microsoft.Agents.AI.Hyperlight package that enables CodeAct-style sandboxed code execution via Hyperlight (hyperlight-sandbox .NET SDK, PR #46) for .NET agents, following the docs/features/code_act/dotnet-implementation.md design and the Python agent_framework_hyperlight reference.
Highlights:
- HyperlightCodeActProvider (AIContextProvider): injects an execute_code tool and CodeAct guidance per invocation; single-instance-per-agent via a fixed StateKeys value; supports multiple provider-owned tools (exposed inside the sandbox via call_tool), file mounts, and an outbound domain allow-list; snapshot/restore per run.
- HyperlightExecuteCodeFunction: standalone AIFunction for manual/static wiring when the sandbox configuration is fixed.
- Approval model via CodeActApprovalMode (AlwaysRequire / NeverRequire) with propagation from ApprovalRequiredAIFunction-wrapped tools.
- Unit tests (instruction builder, tool bridge, approval computation, provider CRUD, ProvideAIContextAsync snapshot isolation and approval wrapping).
- Env-gated integration test (HYPERLIGHT_PYTHON_GUEST_PATH).
- Three samples under samples/02-agents/AgentWithCodeAct (interpreter, tool-enabled, manual wiring).
Build is not yet runnable: requires .NET SDK 10.0.200 and the not-yet-published HyperlightSandbox.Api 0.1.0-preview NuGet package. Package is marked IsPackable=false until the dependency is available.

* Address PR #5329 review feedback for Hyperlight CodeAct provider
- A. Build-breakers: drop unused usings, override test TargetFrameworks
off net472, drop redundant Microsoft.Extensions.AI.Abstractions PackageRef.
- B. API: keep CRUD but rebuild sandbox when config fingerprint changes;
add HyperlightCodeActProviderOptions.CreateForWasm/CreateForJavaScript
factory methods (Backend/ModulePath now read-only); rename WorkspaceRoot
to HostInputDirectory; convert AllowedDomain & FileMount from record to
sealed class; drop ToolBridge.Unwrap (ApprovalRequiredAIFunction is
invocable as-is).
- C. ToolBridge: collapse SerializeResult switch; add comment explaining
AOT-driven choice to keep JsonNode.Parse over typed Deserialize.
- D. InstructionBuilder: drop language-specific 'Python code' phrasing;
strip host filesystem paths from execute_code description.
- E. Style polish: ternary expression-body for ComputeApprovalRequired,
.Where(x is not null), .ToList() over .ToArray() in IReadOnlyList
returns.
- F. Samples: add guest-module / KVM-WHP build instructions to Step01;
note future Excel-upload sample in Step02.
Also adds SandboxExecutorTests covering the new RunSnapshot.ComputeFingerprint
used for sandbox-rebuild detection.

* Align Hyperlight package id and JS warm-up with merged upstream SDK
The .NET SDK in hyperlight-dev/hyperlight-sandbox PR #46 has merged. The
published package id is Hyperlight.HyperlightSandbox.Api (the bare
HyperlightSandbox.Api remains the assembly/namespace) and the reference
CodeExecutionTool uses 'void 0;' as the JavaScript warm-up no-op. Update
the package reference, project comment, README, and SandboxExecutor warm-up
accordingly.
No functional change beyond that — all other public APIs we depend on
(SandboxBuilder.With*, Sandbox.Run/RegisterToolAsync/AllowDomain/Snapshot/
Restore, ExecutionResult, SandboxBackend) match the merged shape.

* Bump Hyperlight package to 0.4.0 and fix build/test issues
Hyperlight.HyperlightSandbox.Api 0.4.0 is now published on nuget.org. Bump
the version reference and address the analyzer/runtime issues that surfaced
once restore could complete:
- Add HyperlightJsonContext source-generated JsonSerializerContext for the
execute_code result + tool error envelopes; route arbitrary AIFunction
results through AIJsonUtilities.DefaultOptions to keep IsAotCompatible=true.
- Replace explicit ObjectDisposedException throws with
ObjectDisposedException.ThrowIf (CA1513).
- Use HyperlightSandbox.Api.SandboxBackend in cref docs to disambiguate.
- Update tests to match AIContext.Tools being IEnumerable<AITool>, drop
ConfigureAwait(false) in xUnit test methods (xUnit1030), use collection
expressions for AllowedDomain methods.
- Add 'using OpenAI.Chat;' to all three samples so AsAIAgent resolves.
- Verified: dotnet build of all four hyperlight projects + samples succeeds
on net8/9/10; dotnet test for the unit tests passes 32/32 on net10.0.

* Fix CI check failures: file encoding (UTF-8 BOM + LF) and broken markdown link
- Convert all new .cs/.csproj files to UTF-8 with BOM and LF line endings
to satisfy the dotnet/.editorconfig charset/end_of_line settings
enforced by check-format.
- Drop unused System.Collections.Generic using in HyperlightCodeActProviderTests.
- Add missing using Microsoft.Extensions.AI in CodeActApprovalMode.cs and
shorten ApprovalRequiredAIFunction cref (IDE0001).
- Fix broken README link to docs/decisions/0024-codeact-integration.md.
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* Address PR review: AIFunction inheritance, packaging, GetService approval check
- HyperlightExecuteCodeFunction now inherits AIFunction directly. The
AsAIFunction() indirection is gone; instances are accepted anywhere an
AIFunction is. Approval requirement is surfaced via GetService<ApprovalRequiredAIFunction>()
which lazily exposes a wrapping ApprovalRequiredAIFunction proxy when the
effective ApprovalMode/tool stack requires it.
- ComputeApprovalRequired now uses GetService<ApprovalRequiredAIFunction>() so
approval-required tools nested anywhere in the AITool decorator stack are
detected (not just the top-most class).
- csproj: drop IsPackable=false (ready to release with the published
Hyperlight.HyperlightSandbox.Api 0.4.0 dependency); add PackageReadmeFile
and pack README.md at the package root, matching the pattern used by
Aspire.Hosting.AgentFramework.DevUI / Microsoft.Agents.AI.DurableTask.
- Update Step03 sample and README wording to reflect direct AIFunction usage.

* Python: Core: rename SessionModeContextProvider to AgentModeProvider
Match the .NET AgentModeProvider class name for cross-language

* Python: Core: address AgentModeProvider review feedback
- default_mode now defaults to None and falls back to the first configured

- get_agent_mode catches ValueError when a previously persisted mode is no
longer in available_modes and resets to the default mode (matching the
non-string recovery branch). Added regression coverage for both behaviors.

* update hyperlight to beta and move samples, add hosted agent sample
* Python: Fix hyperlight WasmSandbox cross-thread Drop and harden sample
Root cause: when a worker-side closure raised, the exception's __traceback__
retained frame locals that included the partially constructed PyO3 sandbox.
Future.result() re-raised that exception on the caller thread, and when the
caller's exception was eventually GC'd the frame locals were released
off-thread, dec_ref'ing the unsendable sandbox from the wrong thread and
tripping the PyO3 panic
'_native_wasm::WasmSandbox is unsendable, but is being dropped on another thread'.
Fix:
* Add _SandboxWorker._run_on_worker which catches every exception on the
worker, drops __traceback__ there, deletes the original exception, and
re-raises a fresh instance on the caller thread. initialize and execute
route through it; dispose keeps its bare-submit semantics.
* Add an opt-in diagnostic module _drop_diagnostic (no-op unless
HYPERLIGHT_TRACE_DROPS=1) that installs a sys.unraisablehook and dumps
owner-thread + per-thread stacks on any future cross-thread unsendable
Drop. Useful for triaging similar PyO3 regressions.
* Tests: cross-thread invocation, traceback-leak isolation, _SandboxEntry
attribute-shape check, and a stale-reference stress test driven through
asyncio.to_thread.
Sample (samples/04-hosting/foundry-hosted-agents/responses/06_hyperlight_codeact):
* Dockerfile installs agent-framework-* from in-tree source with python/ as
build context so unreleased fixes can be validated end-to-end.
* call_server.py pins the Responses API version.
* main.py enables include_detailed_errors=True so future tool failures
surface the actual exception text instead of a bare 'Error: Function
failed.' string.
* README.md documents the in-tree-package build and the Hyperlight
hypervisor requirement (/dev/kvm on Linux, MSHV on Windows). Hosted
environments without hypervisor passthrough surface 'No Hypervisor was
found for Sandbox'; this is a hosting constraint, not a hyperlight bug.

* Python: remove _drop_diagnostic from hyperlight package
The diagnostic module was useful while bisecting the cross-thread Drop bug,

- Preserve exception args when sanitizing tracebacks in _run_on_worker.
- Add public _SandboxWorker.is_alive(); update test to avoid private attr.
- Add namespace coverage tests for agent_framework.hyperlight lazy loader.

Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* Python: Core: address TodoProvider review feedback
- TodoStore.load_state/save_state are now async; TodoFileStore performs
disk I/O via asyncio.to_thread so the event loop is no longer blocked
while the per-session mutation lock is held.
- TodoSessionStore now raises ValueError for malformed top-level state
(non-dict / non-list 'items' / non-int 'next_id') to match the
TodoFileStore contract instead of silently re-defaulting.
- Both stores now clamp next_id to max(item.id) + 1 after load to make
ID collisions impossible after recovery or reconfiguration.
- TodoFileStore writes atomically by writing a sibling temp file and
os.replace-ing it so a crash mid-write cannot truncate the state file.
- TodoFileStore.load_state no longer creates parent directories for
sessions that never write; mkdir is deferred to save_state.
- TodoProvider mutation locks now live in a weakref.WeakKeyDictionary
keyed by AgentSession, so locks for GC'd sessions are evicted instead
of leaking in long-running services.
Tests cover each change including a TodoFileStore-backed end-to-end
provider flow, atomic-write recovery, and lock GC eviction.

* fix(devui): add created_at to custom output item events for correct workflow timings (#5545)
CustomResponseOutputItemAddedEvent and CustomResponseOutputItemDoneEvent lacked a
created_at field, causing the frontend to synthesize timestamps using integer-second
precision with a forced +1s minimum gap between events. This made instant workflows
appear to take 3+ seconds in the DevUI timeline.
Fix:
- Add optional created_at: float | None field to both custom event models
- Populate created_at=float(time.time()) in the mapper for executor_invoked,
executor_completed, and executor_failed events
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* fix(devui): use event created_at for accurate workflow timeline timings
workflow-view.tsx synthesized _uiTimestamp using Math.max(baseTimestamp,
lastTimestamp + 1) with integer-second precision, forcing a minimum 1-second
gap between every sequential event. This made instant workflows appear to take
several seconds in the DevUI timeline.
The fix prefers event.created_at (a float Unix timestamp populated by the
backend mapper for all executor events) and only falls back to the synthetic
timestamp when created_at is absent. This matches the pattern already used in
devuiStore.ts:addDebugEvent.
Added a regression test in test_mapper.py verifying that the mapper attaches
created_at to all executor lifecycle events (invoked, completed, failed).
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* fix(devui): address review feedback for issue #5545
- Read data.timestamp (ISO string) and response.created_at in addition
to top-level created_at when deriving _uiTimestamp, so
response.workflow_event.completed events get a real server timestamp
instead of a synthesized one
- Change uniqueTimestamp tiebreaker: when a real server timestamp is
available use Math.max(eventTimestamp, lastTimestamp) rather than
lastTimestamp + 1, eliminating artificial 1-second gaps while still
preserving monotonic ordering
- Apply the same fix in the HIL streaming path (second setOpenAIEvents
call in workflow-view.tsx)
- Add assert event.created_at > 0 to regression test to guard against
zero or negative timestamps
- Add test_custom_output_item_event_models_have_created_at_field model-
level test so removing the field produces a clear named failure rather
than a downstream ValidationError

* fix(#5545): guard NaN timestamps, fix fallback ID uniqueness, add regression tests
- workflow-view.tsx (×2): Wrap data.timestamp ISO→number conversion in a
Number.isFinite() guard. Python's datetime.now().isoformat() emits
microseconds without a trailing 'Z' (e.g. '2024-01-15T12:34:56.123456'),
which some JS engines cannot parse, returning NaN. NaN !== undefined is
true so the eventTimestamp !== undefined guard did not catch it, poisoning
_uiTimestamp and resetting the monotonic ordering seed (NaN || 0 → 0).
- execution-timeline.tsx: Replace uiTimestamp in the fallback syntheticItemId
with the per-executor runNumber counter. Two runs of the same executor
within the same second previously received identical _uiTimestamp values
and therefore identical syntheticItemIds, causing their output buckets,
state, and run entries to collide (execution-timeline.tsx:360–408).
- Add missing test_workflow_timings_bug.py source file (only a stale .pyc
existed). Three regression tests:
· test_custom_event_models_lack_created_at_field – model field guard
· test_workflow_executor_events_lack_created_at – mapper populates created_at
· test_rapid_workflow_events_have_no_top_level_timestamps – confirms
data.timestamp format that requires the frontend NaN guard

* Make DeclarativeWorkflowExecutor ChatProtocol-compatible for AsAIAgent hosting
Extends the existing DeclarativeWorkflowExecutor<TInput> root executor with
additional ChatProtocol-compatible input routes (string, ChatMessage,
IEnumerable<ChatMessage>, ChatMessage[], TurnToken) so that workflows built
via DeclarativeWorkflowBuilder.Build<TInput>(...) work both for direct
invocation and when hosted via Workflow.AsAIAgent(...).
- Each input message advances the declarative graph immediately; the
TurnToken that the host sends after the message batch is treated as a
no-op since the message has already been processed.
- Conversation id resolution now prefers persisted workflow system state,
then DeclarativeWorkflowOptions.ConversationId, then a newly created
conversation. This makes multi-turn invocations reuse the prior
conversation rather than creating a fresh one each turn.
- The separate DeclarativeChatProtocolStartExecutor and
DeclarativeWorkflowBuilder.BuildChatProtocol overloads introduced
earlier are removed; callers continue to use Build<TInput>(...).
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* fix: use DeclarativeWorkflowContext when reading workflow conversation id
GetWorkflowConversation() requires a DeclarativeWorkflowContext (it calls ReadState which dynamic-casts via the DeclarativeContext helper). The chat-protocol auxiliary handlers receive a BoundWorkflowContext, so calling the extension on the raw IWorkflowContext throws `Invalid workflow context: BoundWorkflowContext`. Use the wrapped declarativeContext that we already constructed.
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* fix: surface ExecutorFailedEvent as ErrorContent in AsAIAgent response
WorkflowSession.InvokeStageAsync only converted WorkflowErrorEvent into an ErrorContent payload. ExecutorFailedEvent fell through to the default branch which emits an empty AgentResponseUpdate carrying the event in RawRepresentation. OutputConverter then mapped that to a workflow_action item with status=failed and dropped the exception entirely, so callers got status=completed and error=null even when an executor threw.
- WorkflowSession.cs: add ExecutorFailedEvent case mirroring WorkflowErrorEvent. Honors _includeExceptionDetails.
- OutputConverter.cs: when an update carries both a WorkflowEvent in RawRepresentation and non-empty Contents, fall through to content processing so the unwrapped error (or any future content payload from a workflow event) is actually emitted.
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* improve: walk inner exceptions when surfacing ExecutorFailedEvent
DeclarativeActionExecutor wraps inner exceptions in DeclarativeActionException with a generic `Unhandled workflow failure` message, hiding the real cause. Walk InnerException so the response shows the full chain (e.g. the underlying HTTP 400 / auth error).
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* Surface declarative SendActivity output as chat content
SendActivityExecutor now emits AgentResponseEvent in addition to
MessageActivityEvent so chat protocols (e.g. AsAIAgent) receive the
formatted activity text. The existing MessageActivityEvent is preserved
for DevUI/observability.
Also extend WorkflowSession.WorkflowOutputEvent handling to accept
AgentResponse payloads, mapping them to their constituent ChatMessages.

* Persist hosted-agent sessions to disk; fix System.LastMessageText
Adds FileSystemAgentSessionStore that writes the serialized AgentSession JSON
(which already embeds the workflow's in-memory checkpoint manager) to a per-
conversation file under /.checkpoints when running in a Foundry hosted env
or {cwd}/.checkpoints locally. Mirrors the python foundry_hosting._responses
FileCheckpointStorage pattern so multi-turn workflow state survives process
restarts without requiring callers to wire up storage themselves.
AddFoundryResponses now defaults to FileSystemAgentSessionStore.CreateDefault()
instead of InMemoryAgentSessionStore; callers can still override via DI.
Also fixes {System.LastMessageText} resolving empty: DeclarativeWorkflowExecutor
.AdvanceAsync was passing the message rehydrated from CreateMessageAsync to
SetLastMessageAsync, but ResponseItem -> ChatMessage round-trip drops the .Text
extension content. Use the original input ChatMessage (which still has the
user-supplied text) and copy the server-assigned MessageId across when present.

* Close multi-modal input parity gaps with python foundry_hosting
InputConverter now mirrors the python _responses.py content handling:
- ComputerScreenshotContent maps to UriContent/HostedFileContent (was dropped).
- Plain TextContent and SummaryTextContent map to MEAI TextContent.
- MessageContentReasoningTextContent maps to MEAI TextReasoningContent.
- input_file with text/* file_data data URIs is decoded inline into
TextContent with a [File: name] prefix, matching python _convert_file_data
so {System.LastMessageText} surfaces the file body. Non-text data URIs and
hosted/url file references preserve filename as AdditionalProperties.
Image/file extraction logic is extracted into shared AppendImageContent and
AppendFileContent helpers used by both the fresh-input and history-replay
switches. Existing 37 InputConverter tests still pass.

* Foundry hosting: round-trip tool-approval (HITL) content as mcp_approval_request/response
Closes the gap where Microsoft.Agents.AI.Foundry.Hosting silently dropped
MEAI ToolApprovalRequestContent/ToolApprovalResponseContent in both
directions. We now serialize them onto the wire as the standard Responses
API mcp_approval_request/mcp_approval_response items with
server_label='agent_framework', and parse the symmetric inbound shapes
back into MEAI content.
Wire format:
- The Responses API only standardizes mcp_approval_* as the approval
primitive. We declare AF as a virtual MCP server via the server_label
field, which is honest for AF's server-side tool-call holding pattern.
- The SDK enforces a strict {prefix}_{50hex} wire-id format, so we hash
the AF RequestId and persist a wireId<->afRequestId mapping in
AgentSession.StateBag so a later mcp_approval_response can be matched
back to the originating workflow request.
Coexists with the existing ConsentAwareMcpClientAIFunction flow
(AgentFrameworkResponseHandler.cs) which emits mcp_approval_request from
a side-channel, not via OutputConverter's content switch.
Known follow-up: python (foundry_hosting/_responses.py) has the same
output-side gap (ToolApprovalRequestContent emission). Out of scope here.
Tests: +9 unit tests covering both fresh-input and history-replay shapes,
StateBag mapping resolution, and the non-FunctionCallContent skip path.
Existing 108 converter tests still pass; full suite 370/370.

* Address PR review feedback for hosted-declarative-dotnet
FileSystemAgentSessionStore reliability/scoping:
- Bound Sanitize() stackalloc at 256 chars, fall back to ArrayPool for longer ids so a long conversationId can no longer crash the hosting process with StackOverflowException.
- Use a Guid-suffixed temp file (\{path}.{guid}.tmp\) so concurrent SaveSessionAsync calls on the same conversation can no longer race on the same temp file. Best-effort temp cleanup on failure.
- Bucket session files by agent.Name when set so two keyed agents that happen to share a conversationId no longer overwrite each other's persisted state. Single-agent / unnamed-agent cases keep the original flat layout (Python parity).
DeclarativeWorkflowExecutor chat-protocol routing:
- ConfigureChatProtocolRoutes uses IsAssignableFrom rather than exact type equality so a broader TInput (object, base interfaces) does not have its inherited inputTransform shadowed by handlers we register here.
- HandleChatMessagesAsync / HandleChatMessageArrayAsync now advance through every message in the batch instead of keeping only the trailing one, so multi-message turns and replayed history are no longer silently truncated. AdvanceAsync gains a finalizeTurn flag so only the last message in the batch sends the result.
Tests:
- New FileSystemAgentSessionStoreTests covering constructor, fresh-session fallback for missing/empty files, root-directory creation, save/get round-trip, agent-Name scoping isolation, long conversationId, invalid-character sanitization, and concurrent-save behavior.
- New InputConverterTests covering AppendFileContent: text/* data URI decode (with and without filename prefix), non-text data URI passthrough, malformed data URI fallback, and filename propagation onto UriContent / HostedFileContent.

* Add tests for remaining PR review feedback (C2, D1, E1)
C2: InputConverter — add 9 tests covering SDK content types that previously
had no coverage:
- SdkTextContent → TextContent (input + output paths)
- SummaryTextContent → TextContent (input + output paths)
- MessageContentReasoningTextContent → TextReasoningContent (input + output)
- ComputerScreenshotContent (HTTP URL → UriContent, data: URI → DataContent,
output path → UriContent)
D1: OutputConverter — add 2 tests for the WorkflowEvent + Contents fall-through:
- WorkflowEvent in RawRepresentation with text Contents must flow through
the content-processing path (text-delta event emitted).
- WorkflowEvent + ErrorContent must produce a failed event rather than be
swallowed by the workflow branch.
E1: SendActivityExecutor — extend CaptureActivityAsync to assert that the
executor emits an AgentResponseEvent carrying the activity text with the
correct ExecutorId and ChatRole.Assistant role.

* Defense-in-depth: neutralize dot-segments in Sanitize and cap TryDecodeTextDataUri input size
Addresses claude-opus-4.6 security review on PR #5589:
- FileSystemAgentSessionStore.Sanitize now replaces all-dot segments
(., .., ...) with underscores so a developer-controlled agent.Name
cannot escape the root directory on Linux (where Path.GetInvalidFileNameChars
only contains NUL and '/').
- InputConverter.TryDecodeTextDataUri rejects encoded payloads larger than
16 MiB before calling Convert.FromBase64String, preventing a single
oversized data URI from triggering a multi-megabyte allocation.
- Adds unit tests covering both fixes.

* Fix Linux-only failure in SaveSessionAsync_SanitizesInvalidPathCharactersAsync
'?' is in Path.GetInvalidFileNameChars only on Windows, not on Linux/macOS,
so the test failed on Ubuntu in CI. Use Path.GetInvalidFileNameChars()[0]

and assert the result no longer contains it.

* Address claude-opus-4.6 security/reliability review feedback
WorkflowSession.cs:
- ExecutorFailedEvent handler no longer leaks the internal executor ID
in error messages. Mirror the WorkflowErrorEvent pattern: surface the
exception's Message when _includeExceptionDetails is true, fall back
to the generic 'An error occurred while executing the workflow.' otherwise.
This also resolves the failing WorkflowHostSmokeTests assertions.
FileSystemAgentSessionStore.cs:
- GetSessionPath no longer has a write side effect. Directory.CreateDirectory
for the per-agent bucket is now performed only on the SaveSessionAsync
path, so a read miss on GetSessionAsync no longer leaves an empty
directory on disk.
- Adds GetSessionAsync_NoExistingFile_DoesNotCreateAgentDirectoryAsync
to lock in the no-side-effect-on-read contract.
OutputConverterTests.cs:
- Strengthen ConvertUpdatesToEventsAsync_ToolApprovalRequest_NonFunctionToolCall_SkippedAsync
to assert exactly one event (the terminal ResponseCompletedEvent) so a
spurious output-item-added/-done leak would now fail the test.

- Drop `previously we kept only the trailing message` comment in
DeclarativeWorkflowExecutor; just describe current loop behavior.

to make the intent obvious at the call site.
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* Address PR review: collision-free Sanitize, MAF-style refactors
- FileSystemAgentSessionStore.Sanitize now percent-encodes invalid chars
(and `%` itself) instead of replacing them with `_`, eliminating
collisions like `foo/bar` vs `foo_bar` mapping to the same bucket.
All-dot segments encode every dot so Windows trailing-dot trimming
cannot reintroduce a navigable name.
- AddFoundryResponses XML doc updated to accurately describe the default
store root (/.checkpoints when hosted, {cwd}/.checkpoints locally).
- DeclarativeWorkflowExecutor.ConfigureChatProtocolRoutes now uses exact
type equality instead of IsAssignableFrom so a broad TInput (e.g.
object) does not skip registering IEnumerable<ChatMessage>, which
ChatProtocolExtensions.IsChatProtocol requires verbatim.
- SendActivityExecutor uses context.YieldOutputAsync(response) instead
of manually constructing AgentResponseEvent, so the activity will
participate in any future OutputFilter coverage.
- WorkflowSession handles AgentResponseEvent in its own switch case,
avoiding the second typecheck against output.Data.

* fix(workflows): bridge declarative HITL through Foundry hosting via IExternalRequestEnvelope
Introduce a new public interface IExternalRequestEnvelope in
Microsoft.Agents.AI.Workflows that lets the runtime peek through a
declarative-layer envelope without taking a circular reference back into
the declarative package. ExternalInputRequest (declarative) implements
it; ExternalInputResponse is constructed via the request's CreateResponse
factory. WorkflowSession unwraps inner AIContent on the request side and
rewraps the client's ChatMessage reply into an ExternalInputResponse on
the response side. PortableValue cannot deserialize directly into an
interface, so TryGetRequestEnvelope resolves the concrete type via
RequestPortInfo.RequestType (TypeId -> Type.GetType) before casting.
Public WorkflowHarness contract preserved: InvokeFunctionToolExecutor
and WorkflowActionVisitor are unchanged from upstream, so public
InvokeToolWorkflowTest scenarios continue to drive
ExternalInputRequest / ExternalInputResponse directly through the
harness.
AgentFrameworkResponseHandler: skip prior conversation history replay
when an existing session is being resumed (workflow checkpoint already
holds the prior messages).
WorkflowSession: when includeExceptionDetails is opted in, also unwrap
DeclarativeActionException so HITL failures are debuggable.

Fixes#5394.
When `background=True` is combined with local function tools,
`FunctionInvocationLayer` calls `_inner_get_response(options=mutable_options)`
repeatedly with the same dict reference across loop iterations. Once the
first poll retrieves a completed background response, `continuation_token`
stays in `mutable_options`, so every subsequent iteration takes the
`continuation_token is not None` branch and `GET`s the same completed
response instead of `POST`ing the tool results. The loop exits after
`max_iterations` with empty text and the model never sees any tool output.
After the retrieve, if the returned `ChatResponse.continuation_token` is
`None` (the background response is no longer in progress), pop
`continuation_token` and `background` from the shared options dict in
place. The next loop iteration then falls through to the normal
`responses.create`/`parse` path and posts tool results.
The diagnosis and a verified runtime monkeypatch are in the issue; this
is the same fix moved in-tree.

* Python: Support GPT-5 verbosity option and restore Foundry agent_reference
Adds verbosity as a typed Literal["low","medium","high"] field on
OpenAIChatOptions (Responses API) and OpenAIChatCompletionOptions (Chat
Completions API), set in the same way as the existing reasoning options.
For the Responses API, top-level verbosity is translated to the nested
text.verbosity shape the OpenAI service expects. The same field flows
through to FoundryChatClient via the existing FoundryChatOptions alias.
Also fixes#5582: PR #5447 removed the agent_reference injection from
RawFoundryAgentChatClient._prepare_options, so first-turn calls against
a Foundry Prompt Agent went out without model and without agent_reference
and were rejected by the Responses API with "Missing required parameter:
'model'". Restores the injection on the non-preview path
(allow_preview=False) and adds a guard test that asserts the preview
path does not inject agent_reference, since the preview SDK injects it
via project_client.get_openai_client(agent_name=...).
Closes#5516Closes#5582
* Python: Address Copilot review on PR #5619
- Foundry verbosity sample docstring: replace the misleading "set deployment
name on model=" instruction with the actual env-var pattern the sample relies
on (FOUNDRY_PROJECT_ENDPOINT and FOUNDRY_MODEL).
- _build_agent_reference docstring: clarify the helper is used for both
Prompt Agents and HostedAgents on the non-preview path.
- Add a Responses API test that locks in the documented precedence rule:
when both top-level verbosity and text["verbosity"] are supplied, the
top-level value wins.
* Python: Drop redundant Foundry verbosity sample and list OpenAI sample in README
- Remove samples/02-agents/providers/foundry/foundry_chat_client_verbosity.py
per review feedback. The verbosity functionality is identical across the
OpenAI and Foundry clients (FoundryChatOptions is an alias of
OpenAIChatOptions), so a single sample on the OpenAI side is sufficient.
- Add the new client_verbosity.py entry to the OpenAI samples README.
* Python: Core: add experimental memory harness context provider

* Address PR feedback: harden memory store IO + consolidation behavior
- Atomic writes via os.replace + temp sibling for topic, state, and index files so
crashes/disk-full failures cannot leave a truncated half-written file.
- Stop creating directories on read paths: list_topics/read_state/search_transcripts
and get_messages return empty when nothing has been written. mkdir is deferred to
the actual save path (write_topic/write_state/save_messages).
- Escape lines that look like markdown headings on render and unescape them on parse,
so a memory or summary containing '## Summary'/'## Memories' cannot tamper with the
topic file structure.
- Narrow extraction/consolidation chat-client failure handling to ChatClientException,
asyncio.TimeoutError, and OSError. Programmer errors (AttributeError, TypeError, ...)
now propagate so misconfigured clients fail loudly.
- Log a payload-prefix preview for every silent shape branch in _extract_memories and
_consolidate_topic so unparsable extractor output is debuggable instead of invisible.
- Restructure _run_consolidation: read maintenance state and topic snapshot under the
state lock, run the LLM consolidation loop without holding the state lock, and only
advance last_consolidated_at/sessions_since_consolidation if at least one topic
succeeded. Transient consolidation failures now leave the maintenance window in
place so the next after_run retries instead of silently sliding forward.
- Add regression tests for: markdown-marker round-trip, atomic-write recovery on
os.replace failure, no-mkdir on pure read paths, transient consolidation failure
preserves state, and propagation of programmer errors.

* docs: clarify MCP trace-context propagation scope for hosted/toolbox tools (#5547)
Automatic W3C trace-context injection via params._meta applies only to
MCP sessions opened by the agent process (MCPStreamableHTTPTool,
MCPStdioTool, MCPWebsocketTool). Hosted MCP tools
(FoundryChatClient.get_mcp_tool) and toolbox-fetched tools
(FoundryChatClient.get_toolbox) execute inside the Foundry agent service
runtime; the framework never issues the tools/call for those and
therefore cannot inject traceparent/tracestate. The previous wording
("for all transports") implied coverage that does not exist.
The updated section:
- removes the inaccurate "for all transports" claim
- adds a Scope paragraph naming the three client-opened transports that
are covered
- explicitly states that propagation across the agent-to-toolbox-to-MCP
boundary is the responsibility of the Foundry service runtime
- documents the workaround (use MCPStreamableHTTPTool directly) for
users who need end-to-end distributed tracing today

exceptions; restricting the carve-out to Foundry was misleading for
readers using other providers
- Fix get_toolbox() wording: use 'await client.get_toolbox(...)' and note
that toolbox.tools is passed into Agent(tools=...) so it reads as an
async instance method call, not a static/class method call
- Add parenthetical '(or any other client-opened MCPTool subclass)' to
future-proof the list of covered transports

returns a types.Tool with an McpServer entry executed by the Gemini
service runtime, so it belongs alongside FoundryChatClient,
OpenAIChatClient, and AnthropicClient in that list.
- Create docs/features/observability/README.md as the learn-site
documentation surface for observability, covering telemetry setup and
MCP trace propagation with the same scope note (including

* Add Python parity for HttpRequestAction in declarative workflow
* Ran pyupgrade and pright to fix CI issues
* Fix conversation ID dot parsing for http executor
* Removed unnecessary export command
* Python: Enforce approval_mode in Claude and GitHub Copilot agents
Tools declared with approval_mode="always_require" were bypassed by the
ClaudeAgent and GitHubCopilotAgent because their SDK-managed tool-calling
loops invoke FunctionTool.invoke() directly via package-supplied handlers,
skipping the standard _try_execute_function_calls approval gate.
Per discussion on #5494, the fix lives in the agents (not in FunctionTool):
any flag added to the tool itself can be spoofed by code with the same
level of access, so the security boundary is the agent that owns the
tool-calling loop.
- Add on_function_approval option to ClaudeAgentOptions and
GitHubCopilotOptions. Callback receives a FunctionCallContent describing
the pending call and returns bool (sync or async).
- Gate FunctionTool.invoke() inside each agent's existing tool-handler
closure when approval_mode == "always_require". Default policy is deny;
callbacks that raise also deny safely.
- Deny path returns a tool-error to the model (Claude: text content;
Copilot: ToolResult(result_type="failure", error="approval_denied"))
so the LLM can react gracefully instead of silently failing.
- Tests for both agents covering: deny by default, sync False, sync True,
async True, callback-raises -> deny, no-op for never_require tools.
- Samples demonstrating sync, async, and deny-by-default flows for both
agents.

raise ValueError if on_function_approval is supplied via per-run options,
instead of silently ignoring it. Approval policy must be set at agent
construction time.

* Increase reliable streaming test timeouts from 30s to 60s
The LLM call through Azure OpenAI + Redis streaming pipeline can exceed
30s in CI due to cold starts or throttling. Raise to 60s to reduce
flaky timeouts while still bounded by pytest's 120s per-test limit.

* Re-enable workflow parallel tests with xdist_group marker
The tests were skipped because xdist distributes module tests across
workers, each spawning their own func process (port conflicts). Adding
xdist_group forces all tests in this module onto a single worker so
the module-scoped function_app_for_test fixture works correctly.

* Foundry.Hosting.UnitTests: extract project from Foundry.UnitTests
Move all Hosting/* tests, three toolbox TestData JSONs, and the FakeAuthenticationTokenProvider/HttpHandlerAssert/TestDataUtil helpers (trimmed to toolbox getters) into a new Microsoft.Agents.AI.Foundry.Hosting.UnitTests project. Add it to the slnx and grant the new assembly InternalsVisibleTo from Microsoft.Agents.AI.Foundry and Microsoft.Agents.AI.Foundry.Hosting.
* Foundry.Hosting.UnitTests: align namespaces to assembly name
Rename namespaces from Microsoft.Agents.AI.Foundry.UnitTests(.Hosting) to Microsoft.Agents.AI.Foundry.Hosting.UnitTests across all moved tests, the duplicated helpers, and the trimmed TestDataUtil. Also fixes the prior namespace inconsistency in FoundryToolboxTests.
* Foundry.Hosting.UnitTests: split WorkflowIntegrationTests by SUT
Replace the WorkflowIntegrationTests file (an IT-named file inside a UT project) with two SUT-focused files plus a shared test-doubles file:
- AgentFrameworkResponseHandlerWorkflowTests.cs - the 5 handler-driven tests that exercise AgentFrameworkResponseHandler with a real workflow agent.
- OutputConverterWorkflowTests.cs - the 5 OutputConverter tests driven by hand-crafted update sequences mirroring real workflow patterns.
- WorkflowTestAgents.cs - StreamingTextAgent and ThrowingStreamingAgent extracted as internal types used by both files.
* Foundry.UnitTests: trim Hosting-related conditionals and dead testdata
Now that Hosting tests live in their own project:
- drop the Compile Remove guard for the Hosting subfolder,
- drop the .NETCoreApp-only PackageReferences (Azure.AI.AgentServer.Responses, Microsoft.AspNetCore.TestHost, OpenTelemetry, OpenTelemetry.Exporter.InMemory),
- drop the conditional ProjectReference to Microsoft.Agents.AI.Foundry.Hosting,
- delete the three Toolbox JSON files and the matching Toolbox getters in TestDataUtil.
* Foundry.Hosting.UnitTests: drop redundant 'using Microsoft.Agents.AI.Foundry.Hosting'
The new project namespace is Microsoft.Agents.AI.Foundry.Hosting.UnitTests, which already brings the parent Microsoft.Agents.AI.Foundry.Hosting namespace into scope. The explicit using statement is therefore redundant (IDE0005). Caught by 'dotnet format --verify-no-changes' running on Linux against the .NET 10 SDK.
* Foundry.Hosting: drop InternalsVisibleTo to Foundry.UnitTests
The non-hosting Foundry.UnitTests project no longer holds any Hosting tests after the split, so it doesn't need access to internal types in Microsoft.Agents.AI.Foundry.Hosting. Only Microsoft.Agents.AI.Foundry.Hosting.UnitTests needs it.
* Foundry.Hosting: rename DelegatingResponsesClient to UserAgentResponsesClient
Address westey-m's review feedback on PR #5453: `Delegating*` is conventionally reserved for inheritable base classes (mirroring `DelegatingHandler`) where consumers override one or two members. This polyfill is sealed and only injects the User-Agent supplement, so the new name reflects its actual purpose.
Renamed via `git mv` to preserve history:
* `src/Microsoft.Agents.AI.Foundry.Hosting/DelegatingResponsesClient.cs` to `UserAgentResponsesClient.cs`
* `tests/Microsoft.Agents.AI.Foundry.Hosting.UnitTests/DelegatingResponsesClientTests.cs` to `UserAgentResponsesClientTests.cs`
Class, constructor, and all references updated across:
* `src/.../UserAgentResponsesClient.cs` (class + constructor + internal log message)
* `src/.../ServiceCollectionExtensions.cs` (cref + type check + instantiation)
* `src/.../HostedAgentUserAgentPolicy.cs` (cref)
* `tests/Foundry.UnitTests/RequestOptionsExtensionsTests.cs` (comment)
* `tests/Foundry.Hosting.UnitTests/UserAgentResponsesClientTests.cs` (class + cref + instantiations)
* Python: Fix hosted MCP replay producing orphan function_call_output
Resolves part of #5546. After a turn ran a hosted MCP / Foundry-toolbox-MCP
tool, the next turn's replayed input array carried a function_call_output
with an mcp_* call_id and no matching function_call, and the Responses API
returned a 400.
Two layers covered here:
* Chat-client serialize layer (packages/openai): adds mcp_server_tool_call
and mcp_server_tool_result cases to _prepare_message_for_openai and
_prepare_content_for_openai. Pairs are coalesced via a post-pass into a
single mcp_call input item carrying both arguments and output. Orphan
results are dropped (debug-logged) rather than serialized as orphan
function_call_output, which is what the Responses API rejected.
* Host read layer (packages/foundry_hosting): _item_to_message and
_output_item_to_message now route custom_tool_call_output whose
call_id.startswith("mcp_") to Content.from_mcp_server_tool_result.
Non-mcp_ call_ids continue to produce Content.from_function_result.
Symmetric with the host write-side choice for hosted-MCP results.
Two further fixes (agentserver SDK additions, host write-side single-item
emission) remain tracked on the issue and depend on an SDK release.
* Python: Fix pyright unknown-type in _stringify_mcp_output
cast(Sequence[Any], output) after the isinstance check so pyright stops
flagging the loop variable as unknown. Also normalizes a couple of
em-dashes in docstrings I introduced in the prior commit.
* Python: Harden _stringify_mcp_output for dict-shaped MCP outputs
Address Copilot review on PR #5581. Today the helper falls back to
str() for any non-string, non-text-attribute entry, which produces
Python repr (single-quoted dicts) for the canonical MCP raw-JSON
text-content shape `{"type": "text", "text": "..."}` and any other
dict-shaped output.
Three small changes:
* List-entry path: prefer plain string entries, then `.text` attribute
(Content objects), then `entry["text"]` for Mapping entries in the
canonical MCP shape, then JSON-encode anything else.
* Final fallback: `json.dumps(output, default=str)` so Mappings and
scalars produce valid JSON rather than Python repr.
* Two new unit tests covering the dict-with-text shape and the
non-text-dict JSON fallback.
* Python: Suppress mypy redundant-cast on _stringify_mcp_output narrowing
The cast is needed by pyright (reportUnknownVariableType) but mypy
considers it redundant after the preceding isinstance narrowing.
Pyright's behavior is correct for the strict-mode reporting we run,
so keep the cast and silence mypy on the line.
* dotnet: Add hosted-agent User-Agent supplement to outgoing requests
When an agent runs inside a Foundry Hosted Agent, the outgoing
User-Agent header now includes 'agent-framework-hosted/{version}'
alongside the existing 'MEAI/{version}' segment.
- Add HostedAgentContext with AsyncLocal<string?> property
- MeaiUserAgentPolicy reads the supplement per-call
- AgentFrameworkResponseHandler sets/restores the context

* Trying to get UA flowing, no luck yet.
* .NET: Polyfill MEAI OpenAIResponsesChatClient to add hosted-agent User-Agent supplement
When AgentFrameworkResponseHandler resolves an agent (i.e. we are running in a
hosted context), TryApplyUserAgent walks the agent's IChatClient decorator chain
to find MEAI's internal OpenAIResponsesChatClient and reflectively swaps its
inner _responseClient field with a DelegatingResponsesClient wrapper. The
wrapper overrides the public-virtual protocol methods to add a per-call
HostedAgentUserAgentPolicy to the RequestOptions and delegate to the inner
ResponsesClient. The OpenAI SDK's internal streaming overloads bottom out in
calls to the public-virtual non-streaming overloads via virtual dispatch on
this, so streaming is covered without overriding any non-virtual member.
The wrapper accepts any ResponsesClient-derived inner — both the Foundry
ProjectResponsesClient and the native OpenAI ResponsesClient — and preserves
the inner client's full pipeline (Transport, RetryPolicy, NetworkTimeout,
OrganizationId / ProjectId / UserAgentApplicationId, custom policies).
- Add DelegatingResponsesClient + HostedAgentUserAgentPolicy in Microsoft.Agents.AI.Foundry.Hosting.
- Add TryApplyUserAgent next to ApplyOpenTelemetry in FoundryHostingExtensions; wire it into AgentFrameworkResponseHandler.GetAgent for both keyed and default-agent paths.
- Drop earlier-iteration dead code: AddHostedAgentTelemetry extension, HostedUserAgentPolicy class, HostedAgentContext.cs, and the never-called ToRequestOptions helper.
- Revert RequestOptionsExtensions.MeaiUserAgentPolicy to MEAI-only (the supplement is now injected by the polyfill).
- Revert unrelated whitespace change in Agent_Step25_ToolboxServerSideTools sample.
- Tests cover streaming AND non-streaming, retry policy preservation, OrganizationId/ProjectId/UserAgentApplicationId pass-through, idempotency, native OpenAI ResponsesClient, and reflection guards for MEAI/OpenAI shape drift.
* .NET: Address review feedback on hosted-agent User-Agent polyfill
- TryApplyUserAgent: replace silent null-return with ArgumentNullException to match the codebase's convention.
- Add idempotency test (TryApplyUserAgent_CalledTwiceOnSameAgent_DoesNotDoubleWrap) — runs the polyfill twice on the same agent and asserts the wire UA contains exactly one foundry-hosting segment, proving the 'current is DelegatingResponsesClient' guard prevents nested wrapping.
- Add retry-double-append test (Polyfill_RetryWithinCall_DoesNotDuplicateSupplementInUserAgent) — exercises the HostedAgentUserAgentPolicy Contains-guard via a custom retry policy that re-runs the inner pipeline on the same message.
- Replace TryApplyUserAgent_NullAgent_ReturnsNullWithoutThrowing with TryApplyUserAgent_NullAgent_ThrowsArgumentNullException to match the new contract.
* .NET: Drop null check from TryApplyUserAgent and its now-redundant test
The two call sites in AgentFrameworkResponseHandler.GetAgent already null-check the agent before invoking TryApplyUserAgent, so the defensive ArgumentNullException is unreachable. Remove it and the corresponding test.
* .NET: Remove unused Microsoft.Shared.Diagnostics import in ServiceCollectionExtensions
The Throw.IfNull helper from this namespace was used by the now-removed null check in TryApplyUserAgent. Drop the unused import to satisfy IDE0005 in CI's full-project dotnet format run.

* Python: bump package versions for 1.2.2 release
PATCH bump (1.2.1 -> 1.2.2) for the released cohort. Five PRs land in this
window:
- agent-framework-openai: fix file_search citations breaking the assistant-
message history roundtrip (#5557) — drives the released-tier PATCH
- agent-framework-orchestrations: [BREAKING] standardize orchestration
terminal outputs as AgentResponse (#5301)
- agent-framework-core, agent-framework-declarative: preserve Workflow.run()
shared state across calls, accept list[Message] in declarative start
executor, and coerce Enum values when serializing PowerFx symbols (#5531)
- agent-framework-foundry-hosting: add hosted Durable Workflow support
(#5531)
- agent-framework-azure-contentunderstanding: new alpha package — Azure AI
Content Understanding context provider (#4829)
- dependencies: workspace package dependency refresh (#5555)
Per lockstep convention, all 21 beta packages stamp 1.0.0b260429 and all 4
alpha packages (now including the new contentunderstanding) stamp
1.0.0a260429. Date stamp reflects 2026-04-29 Pacific. Every non-core package
floor on agent-framework-core is raised to >=1.2.2; the new
contentunderstanding package's stale >=1.0.0 floor is brought into line.
Two follow-on fixes bundled to keep validate-dependency-bounds-test green
at lowest-direct resolution:
- Bump agent-framework-azure-contentunderstanding's azure-ai-content
understanding lower bound from >=1.0.0 to >=1.0.1 (1.0.0 ships without
proper typing — pyright reports 65 unknown-type errors)
- Add pyright ignore comments to core/foundry/__init__.pyi for the new
alpha package's type-stub imports, since alpha packages are not in
core's [all] extra and therefore aren't installed at lowest-direct
* Python: add #5552 to 1.2.2 CHANGELOG
Add the streaming-span observability fix to the Fixed section. PR is on
upstream/main but not yet pulled into origin/main; the code itself will
land via the PR merge.
* Python: address PR #5561 review feedback on dependency bounds
Two packaging fixes flagged in review:
1. agent-framework-azure-contentunderstanding: add agent-framework-foundry
as a runtime dependency. The package's README directs users to
`pip install agent-framework-azure-contentunderstanding --pre` and the
basic example imports `FoundryChatClient` from `agent_framework.foundry`,
so the documented install path was failing with ImportError. Pulling
agent-framework-foundry into deps makes the advertised entry path
self-contained.
2. agent-framework-foundry: bump agent-framework-openai lower bound from
>=1.1.0 to >=1.2.2,<2. Foundry imports private modules from
agent_framework_openai (`_chat_client.py:22`, `_agent.py:34`), so
resolvers were free to pair foundry==1.2.2 with older OpenAI versions
that lack this release's coordinated Responses/history fix. Lockstep the
floor with the released cohort to prevent mismatched installs.
Both changes pass `validate-dependency-bounds-test` lower + upper at
their respective packages.
* Python: Fix file_search citations breaking assistant history roundtrip
The Responses API rejects 'input_file' inside an assistant message, but the
SDK was emitting it whenever an assistant Message contained a hosted_file
content (which is what file_search citations become). Three coordinated fixes:
1. _prepare_content_for_openai now skips hosted_file for the assistant role
instead of mapping to input_file (which the API rejects there).
2. The streaming response.output_text.annotation.added handler attaches
file_citation, container_file_citation, and file_path as annotations on
text content, matching the non-streaming path. Previously streaming
produced standalone HostedFileContent items that always tripped (1).
3. output_text serialization preserves Annotation objects on roundtrip via a
new _annotations_to_output_text helper instead of hardcoding 'annotations'
to []. file_search citations now survive multi-agent forwarding.
Closes#5556.
* Address PR review
- _annotations_to_output_text: fan out one entry per annotated_region for
url_citation/container_file_citation (Annotation.annotated_regions is a
Sequence; the API form carries one start/end per entry).
- Validate region span bounds are ints before emitting; skip otherwise.
- Add test for the file_path branch (annotation with file_id only).
- Add test verifying streamed citation events coalesce onto surrounding
text via _finalize_response so span indices reference the merged text,
not the empty-text streaming carrier.
* Update dependencies
* Preserve mcp[ws] and uvicorn[standard] extras in override-dependencies
Bare-package overrides on mcp and uvicorn dropped the [ws] and [standard]
extras (and their transitive deps like httptools, watchfiles) from the
generated lock. Re-add the extras to the overrides so the lock matches
what workspace packages actually request.
* Fix declarative Workflow.as_agent() by accepting list[Message] in start executor
The declarative start executor (JoinExecutor) only advertised dict and str
in its input_types, so WorkflowAgent.__init__ rejected it with
'Workflow's start executor cannot handle list[Message]'.
Add list[Message] to the JoinExecutor handler annotation and add a
matching branch in DeclarativeActionExecutor._ensure_state_initialized
that extracts the last user-message text and falls through to the
string-input initialization path, so =System.LastMessageText works
end-to-end via as_agent().
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* Populate Conversation.messages from list[Message] trigger
When Workflow.as_agent() is invoked with a list[Message], the start executor now populates Conversation.messages / Conversation.history / System.conversations.{id}.messages with prior turns only (excluding the latest user message), and surfaces the latest user message via Inputs.input and System.LastMessage*. This matches InvokeAzureAgent's contract that the messages binding holds prior turns and the executor itself appends the new user input before invoking, avoiding double-append of the trailing user turn while preserving full history (incl. assistant/system/tool roles and multi-modal content) for downstream actions.
* Coerce Enum values when serializing PowerFx symbols
MessageRole and other str-subclass Enums passed isinstance(v, str) and were forwarded to pythonnet unchanged. pythonnet then raised 'MessageRole value cannot be converted to System.String' for every PowerFx primitive when ConditionGroup/Expr eval walked the symbol table containing Conversation.messages. Reduce Enum members to their underlying value before the primitive check so eval sees plain strings/ints.
* Foundry hosting: pass full conversation history to workflow agents
_handle_inner_workflow only forwarded the latest user turn to WorkflowAgent.run, even though _handle_inner_agent already prepends history fetched from Foundry storage to the messages it sends a regular agent. Declarative workflows reset Conversation.messages on every run (state.initialize), so checkpoint replay alone does not give them prior turns - the host has to pass them in, the same way it does for non-workflow agents. Mirror that contract: fetch context.get_history() and pass [*history, *input_messages] to the workflow agent.
* feat(workflows): support combined message + checkpoint_id for multi-turn continuation
Allow Workflow.run(message=..., checkpoint_id=...) so callers can restore
prior workflow state from a checkpoint AND deliver a new message to the
start executor in a single call. The existing reset_context logic
already preserves shared state when checkpoint_id is set, so this gives
us 'fresh start executor invocation with prior state intact' - exactly
what hosted multi-turn declarative workflows need.
- _workflow.py: drop the message+checkpoint_id mutual exclusion and
update _execute_with_message_or_checkpoint to do both (restore then
execute) when both are provided.
- _agent.py: in _run_core's checkpoint branch, also forward
input_messages so WorkflowAgent.run(messages, checkpoint_id=...) works
end-to-end. Falls back to the legacy 'restore only' behavior when
messages are absent.
- _declarative_base.py: detect continuation in _ensure_state_initialized
by checking whether DECLARATIVE_STATE_KEY already exists in shared
state; if so, refresh inputs/LastMessage* and append non-user trigger
messages instead of calling state.initialize() (which would wipe
Conversation/Local/System).
- foundry_hosting/_responses.py: collapse the host's two-call pattern
(restore-only, then fresh run) into a single combined call now that
the underlying APIs support it.
- tests: drop the assertion that combined message+checkpoint_id raises.

* Pivot: preserve workflow state across run() calls
Replace the prior 'combined message + checkpoint_id in one run()' approach
with a cleaner default: Workflow.run no longer wipes shared state or runner-
context messages between calls. Iteration counting and per-run kwargs still
reset on a fresh-message run; checkpoint and responses runs are continuations
that preserve everything.
This lets a WorkflowAgent be invoked repeatedly on the same instance and
maintain multi-turn context (e.g. accumulated Conversation.messages) without
asking developers to opt in. Hosted-agent multi-turn pattern becomes two
explicit calls: restore-from-checkpoint (drive to idle), then run-with-message.
Key changes:
- _workflow.py: drop _state.clear() and reset_for_new_run() from run().
Reset iteration count and run kwargs on fresh-message runs only.
Restore 'Cannot provide both message and checkpoint_id' validation.
Add async guard: fresh-message run with un-drained pending executor
messages from a prior run is invalid.
- _runner.py: clear _state before import_state in restore_from_checkpoint
so restore is authoritative (import_state merges, not replaces).
- _agent.py: revert checkpoint branch to restore-only (no message forward).
- _responses.py (foundry_hosting): two-call host pattern - restore checkpoint
silently, then run with new user input.
- tests: state-preservation is the new default; rebuild Workflow for clean slate.

* Address PR review: fix Inputs.input update and checkpoint storage path
- _declarative_base.py: continuation branch was writing 'Inputs.input' via
state.set, which routes to the Custom namespace and never updates the
PowerFx-visible Workflow.Inputs.input. Update state_data['Inputs'] in
place via get_state_data / set_state_data so =Workflow.Inputs.input and
=inputs.input see the new turn's user text on continuation.
- _declarative_base.py: refresh docstring to clarify that on a list[Message]
trigger, Conversation.messages excludes the current user message at the
start of the turn (agent executors append it before invoking the inner
agent).
- _responses.py: when previous_response_id is supplied (no conversation_id),
the prior checkpoint lives under <storage>/<previous_response_id> but new
checkpoints must land under <storage>/<current_response_id> for the next
turn to find them. Hold onto restore_storage from the get_latest lookup
and pass it to the restore-only run; pass write_storage (current id) to
the message-delivery run and to checkpoint cleanup.

* Fix pyright errors in _declarative_base.py for CI
- Replace state._state.get(...) protected access with new public
is_initialized() method on DeclarativeWorkflowState (also clearer intent
for the continuation detection use case).
- Add narrow pyright ignores for the Any-typed trigger paths that pyright
cannot fully narrow (the list[Message] isinstance loop and the
fallback-DefaultTransform branch).

* Address Copilot review batch: tests + Workflow.reset escape hatch
* Add Workflow.reset() public method as recovery escape hatch when an

workflow is not checkpointed. Update the in-flight messages guard's
error message to point callers at it.
* Add test_workflow_run_inflight_messages_guard exercising both the

* Add test_workflow_reset_rejects_concurrent_runs to lock down the
in-progress guard on reset.
* Add test_as_agent_continuation_preserves_prior_state covering the
is_continuation branch in _ensure_state_initialized: stamps a marker
between calls and asserts it survives, while Inputs.input and
System.LastMessageText refresh to the new turn.
* Add test_powerfx_safe.py regression tests for the Enum branch in
_make_powerfx_safe (str-subclass, int-subclass, plain Enum, and

* Skip restore-only pre-pass when checkpoint has pending request_info
Address Copilot review on _responses.py: the restore-only checkpoint
replay populates self._agent.pending_requests for any request_info
events captured in the checkpoint. The follow-up run(input_messages)
call would then route through WorkflowAgent._process_pending_requests,
which expects function-response content and rejects plain text input
as 'unexpected content while awaiting request info responses'.
Workflows resumed from a checkpoint that was idle-with-pending-requests
would therefore fail every subsequent plain-text user turn. Inspect the
loaded checkpoint and skip the pre-pass when its
pending_request_info_events dict is non-empty. Workflows that don't use
request_info (the current sample set) are unaffected; workflows that do
will fall through to a fresh-message run rather than silently corrupting
the routing state.

* Loosen azure-ai-agentserver-* pins to major version
The exact-version pins on azure-ai-agentserver-{core,responses,invocations}
forced foundry-hosting consumers to upgrade in lockstep with every beta
bump from upstream. Switch to '>=current,<next-major' so we pick up patch

* Drop Workflow.reset(); checkpointing is the recovery path
The in-flight-messages guard prevented silent misbehavior, but the
companion Workflow.reset() escape hatch only cleared _messages while
leaving iteration count, executor-local state, and shared State
mutations in an indeterminate condition after a mid-run failure. That
gave a false sense of recovery.
Recovery from a mid-run failure is supported only via checkpoint
restoration. Keep the guard and reframe its error message accordingly;
remove reset() and its tests.

* Address Tao's review on PR 5531
- Rename Workflow._run_workflow_with_tracing parameter
is_fresh_message_run -> is_continuation (default False, inverted).
Fresh-message turns reset per-run accounting; continuations
(checkpoint restores, responses replays) preserve it.
- Simplify the in-flight-messages guard: _validate_run_params already
enforces that 'message' is mutually exclusive with 'checkpoint_id'
and 'responses', so the additional checks were dead code.
- foundry_hosting _responses: move the restore-only pre-pass above
emit_created/emit_in_progress; restore is preparation, not run
progress. Drop the skip-restore gate (state preservation requires
unconditional restore) and instead clear agent.pending_requests
after the restore-only call. Collapse over-conditioned check.

* Don't clear pending_requests after restore-only pre-pass
Pending requests in the restored checkpoint represent genuinely
outstanding HITL requests. The next user input may carry function
responses (Responses API `function_call_output` items become
FunctionResultContent / FunctionApprovalResponseContent), which
`WorkflowAgent._process_pending_requests` correctly extracts and
matches against the populated `pending_requests`. Clearing them
after restore would silently drop that state and force the next turn
to be treated as a fresh input even when the caller is responding to
the outstanding requests.

* Fix orchestration outputs so as_agent() returns the final answer only. Align other orchestration outputs
* Fix orchestration output issues from review comments
1. Sample cleanup: Remove commented-out FoundryChatClient block and update
prerequisites to reference OPENAI_CHAT_MODEL_ID instead of FOUNDRY_* vars.
2. Sequential approval output: Change _EndWithConversation.end_with_agent_executor_response
from a no-op sink to yield response.agent_response. When the last participant is
AgentApprovalExecutor (via with_request_info), _EndWithConversation is the output
executor so the yield produces the terminal answer. When the last participant is a
regular AgentExecutor, _EndWithConversation is not in output_executors so the yield
is silently filtered out.
3. Forward data events through WorkflowExecutor: _process_workflow_result now also
forwards 'data' events from sub-workflows so that emit_intermediate_data=True on
AgentExecutor works correctly when wrapped in AgentApprovalExecutor.
4. Concurrent docstring: Update _AggregateAgentConversations docstring to say
'deterministic participant order' instead of 'completion order'.
5. Add test_concurrent_intermediate_outputs_emits_data_events verifying that
ConcurrentBuilder(intermediate_outputs=True) emits per-participant data events
alongside the single aggregated output event.

* Add tests for sequential workflow with_request_info and intermediate_outputs (#5301)
Address PR review comments 2, 3, and 5:
- Add test_sequential_request_info_last_participant_emits_output:
Verifies that when the last participant is wrapped via with_request_info()
(AgentApprovalExecutor), the workflow still emits a terminal output after
approval, exercising the _EndWithConversation.end_with_agent_executor_response
fallback path.
- Add test_sequential_request_info_with_intermediate_outputs_emits_data_events:
Verifies that emit_intermediate_data=True works correctly through
AgentApprovalExecutor wrapping—WorkflowExecutor._process_result already
forwards data events from sub-workflows, so intermediate agent responses
surface as data events in the parent workflow.

* Fix pyright type errors from AgentResponse output refactor (#5301)
Update cast() calls in _group_chat.py and _magentic.py to use
WorkflowContext[Never, AgentResponse] instead of the old
WorkflowContext[Never, list[Message]], matching the updated method
signatures in _base_group_chat_orchestrator.py.
Fix _sequential.py _EndWithConversation.end_with_agent_executor_response
to declare WorkflowContext[Any, AgentResponse] so yield_output accepts
AgentResponse[None].
Fix _workflow_executor.py data event forwarding to handle nullable
executor_id.
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* Fix pyright reportUnknownVariableType in _agent.py (#5301)
Extract event.data into a typed local variable before the isinstance
check to avoid pyright narrowing it to AgentResponse[Unknown].
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* Fix pyright reportMissingImports for orjson in file history samples (#5301)
Add pyright: ignore[reportMissingImports] to orjson imports that are
already guarded by try/except ImportError, matching the existing pattern
used elsewhere in the samples.

* Address ultrareview feedback: emit_data_events rename + WorkflowAgent reasoning conversion
Layered on top of the prior review-feedback work in this branch.
Renames:
- AgentExecutor.emit_intermediate_data -> emit_data_events (mechanical
rename; orchestration semantics live at the orchestration layer, not
the general-purpose executor). Forwarded through MagenticAgentExecutor,
AgentApprovalExecutor, and all orchestration call sites.
- HandoffAgentExecutor._check_terminate_and_yield -> _should_terminate
(pure predicate; no longer yields anything). HandoffBuilder docstring
rewritten to describe the new per-agent AgentResponse output contract.
WorkflowAgent reasoning-content conversion:
- Add _rewrite_text_to_reasoning(contents) and _msg_as_reasoning(msg)
helpers; the as_agent() path now reframes text content from data events
as text_reasoning Content blocks before merging into the AgentResponse.
- Consumers iterate msg.contents and branch on content.type — same path
they already use for Claude thinking and OpenAI reasoning. No new
field on Message/AgentResponse/WorkflowEvent.
- Streaming branch constructs fresh AgentResponseUpdate instances instead
of mutating shared payloads (regression test added).
- Helper _msg_maybe_reasoning consolidates the conditional rewrite at
three call sites in the non-streaming conversion.
Tests:
- TestWorkflowAgentReasoningHelpers + TestWorkflowAgentDataEventReasoningConversion
add 9 new tests covering helpers, non-streaming, streaming, mixed content,
already-reasoning passthrough, and mutation-safety regression.
- Updated test_sequential_as_agent_with_intermediate_outputs_includes_chain
to assert text_reasoning content for intermediate agents.
* Fix pyright: widen event.data to Any to avoid partial-unknown narrowing
The streaming conversion path narrowed event.data via isinstance against
generic AgentResponse, producing AgentResponse[Unknown] and tripping
reportUnknownVariableType/reportUnknownMemberType. Binding data: Any
before the check keeps runtime behavior identical while restoring a fully
known type for downstream access.
* Clean up design
* Scope to agent output semantics only
* yield AgentResponseUpdate streaming, AgentResponse non-streaming
* Fix mypy/pyright: widen cast types at GroupChat callsites
Eight callsites in _group_chat.py still cast to WorkflowContext[Never,
AgentResponse] but the base orchestrator methods now accept the wider
WorkflowContext[Never, AgentResponse | AgentResponseUpdate] (mode-aware
yields). W_OutT is invariant, so the narrower cast is not assignable.
Magentic was widened in the same commit; this catches the GroupChat
callsites that were missed.
* Python: skip flaky Foundry / Foundry Hosting integration tests (#5553)
These two integration tests have been failing in the merge queue across
multiple unrelated PRs (5301, 5531). Both are marked `@pytest.mark.flaky`
with 3 retries, but all attempts fail back-to-back. Skipping both with a
reason pointing to #5553 so they can be fixed properly without continuing
to block unrelated merges.

* Add declarative HttpRequestAction support to workflows
* Clean up response body for diagnostics and fix tests.
* Fix merge with main.
* Remove redundant fallback for request content headers.
* feat: add agent-framework-azure-contentunderstanding package
Add Azure Content Understanding integration as a context provider for the
Agent Framework. The package automatically analyzes file attachments
(documents, images, audio, video) using Azure CU and injects structured
results (markdown, fields) into the LLM context.
Key features:
- Multi-document session state with status tracking (pending/ready/failed)
- Configurable timeout with async background fallback for large files
- Output filtering via AnalysisSection enum
- Auto-registered list_documents() and get_analyzed_document() tools
- Supports all CU modalities: documents, images, audio, video
- Content limits enforcement (pages, file size, duration)
- Binary stripping of supported files from input messages
Public API:
- ContentUnderstandingContextProvider (main class)
- AnalysisSection (output section selector enum)
- ContentLimits (configurable limits dataclass)
Tests: 46 unit tests, 91% coverage, all linting and type checks pass.
* fix: update CU fixtures with real API data, fix test assertions
- Replace synthetic fixtures with real CU API responses (sanitized)
- Update test assertions to match real data (Contoso vs CONTOSO,
TotalAmount vs InvoiceTotal, field values from real analysis)
- Add --pre install note in README (preview package)
- Document unenforced ContentLimits fields (max_pages, duration)
* chore: add connector .gitignore, update uv.lock
* refactor: rename to azure-ai-contentunderstanding, fix CI issues
Align naming with Azure SDK convention and AF pattern:
- Directory: azure-contentunderstanding -> azure-ai-contentunderstanding
- PyPI: agent-framework-azure-contentunderstanding -> agent-framework-azure-ai-contentunderstanding
- Module: agent_framework_azure_contentunderstanding -> agent_framework_azure_ai_contentunderstanding
CI fixes:
- Inline conftest helpers to avoid cross-package import collision in xdist
- Remove PyPI badge and dead API reference link from README (package not published yet)
* feat: add samples (document_qa, invoice_processing, multimodal_chat)
- document_qa.py: Single PDF upload, CU context provider, follow-up Q&A
- invoice_processing.py: Structured field extraction with prebuilt-invoice
- multimodal_chat.py: Multi-file session with status tracking
- Add ruff per-file-ignores for samples/ directory
- Update README with samples section, env vars, and run instructions
* feat: add remaining samples (devui_multimodal_agent, large_doc_file_search)
- S3: devui_multimodal_agent/ — DevUI web UI with CU-powered file analysis
- S4: large_doc_file_search.py — CU extraction + OpenAI vector store RAG
- Update README and samples/README.md with all 5 samples
* feat: add file_search integration for large document RAG
Add FileSearchConfig — when provided, CU-extracted markdown is automatically
uploaded to an OpenAI vector store and a file_search tool is registered on
the context. This enables token-efficient RAG retrieval for large documents
without users needing to manage vector stores manually.
- FileSearchConfig dataclass (openai_client, vector_store_name)
- Auto-create vector store, upload markdown, register file_search tool
- Auto-cleanup on close()
- When file_search is enabled, skip full content injection (use RAG instead)
- Update large_doc_file_search sample to use the integration
- 4 new tests (50 total, 90% coverage)
* fix: add key-based auth support to all samples
Follow established AF pattern: check for API key env var first,
fall back to AzureCliCredential. Supports AZURE_OPENAI_API_KEY and
AZURE_CONTENTUNDERSTANDING_API_KEY environment variables.
* FEATURE(python): add analyzer auto-detection, file_search RAG, and lazy init
_context_provider.py:
- Make analyzer_id optional (default None) with auto-detection by media
type prefix: audio->audioSearch, video->videoSearch, else documentSearch
- Add _ensure_initialized() for lazy client creation in before_run()
- Add FileSearchConfig-based vector store upload
- Fix: background-completed docs in file_search mode now upload to vector
store instead of injecting full markdown into context messages
- Add _pending_uploads queue for deferred vector store uploads
devui_file_search_agent/ (new sample):
- DevUI agent combining CU extraction + OpenAI file_search RAG
azure_responses_agent (existing sample fix):
- Add AzureCliCredential support and AZURE_AI_PROJECT_ENDPOINT fallback
Tests (19 new), Docs updated (AGENTS.md, README.md)
* feat(cu): MIME sniffing, media-aware formatting, unified timeout, vector store expiration
- Add three-layer MIME detection (fast path → filetype binary sniff → filename
fallback) to handle unreliable upstream MIME types (e.g. mp4 sent as
application/octet-stream). Adds filetype>=1.2,<2 dependency.
- Media-aware output formatting: video shows duration/resolution + all fields
as JSON; audio promotes Summary as prose; document unchanged.
- Unified timeout for all media types (removed file_search special-case that
waited indefinitely for video/audio). All files use max_wait with background
polling fallback.
- Vector store created with expires_after=1 day as crash safety net.
- Add 8 MIME sniffing tests (TestMimeSniffing class).
* fix: merge all CU content segments for video/audio analysis
CU's prebuilt-videoSearch and prebuilt-audioSearch analyzers split long
media files into multiple `contents[]` segments. Previously,
`_extract_sections()` only read `contents[0]`, causing truncated
duration, missing transcript, and incomplete fields for any video/audio
longer than a single scene.
Now iterates all segments and merges:
- duration: global min(startTimeMs) → max(endTimeMs)
- markdown: concatenated with `---` separators
- fields: same-named fields collected into per-segment list
- metadata (kind, resolution): taken from first segment
Single-segment results (documents, short audio) are unaffected.
Update test fixture to realistic 3-segment video structure and expand
assertions to verify multi-segment merging. Add documentation for
multi-segment processing and speaker diarization limitation.
* refactor: improve CU context provider docs and remove ContentLimits
- Improve class docstring: clarify endpoint (Azure AI Foundry URL with
example), credential (AzureKeyCredential vs Entra ID), and analyzer_id
(prebuilt/custom with auto-selection behavior and reference links)
- Add SUPPORTED_MEDIA_TYPES comments explaining MIME-based matching
behavior and add missing file types per CU service docs
- Use namespaced logger to align with other packages
- Remove ContentLimits and related code/tests
- Rename DEFAULT_MAX_WAIT to DEFAULT_MAX_WAIT_SECONDS for clarity
* feat: support user-provided vector store in FileSearchConfig
- Add vector_store_id field to FileSearchConfig (None = auto-create)
- Track _owns_vector_store to only delete auto-created stores on close()
- Remove vector_store_name; use internal _DEFAULT_VECTOR_STORE_NAME
- Add inline comments for private state fields
- Document output_sections default in docstring
- Update AGENTS.md, samples, and tests
* fix: remove ContentLimits from README code block
* refactor: create CU client in __init__ instead of __aenter__
Follow Azure AI Search provider pattern: create the client eagerly in
__init__, make __aenter__ a no-op. This ensures __aexit__/close() is
always safe to call and eliminates the _ensure_initialized() workaround.
* docs: add file_search param to class docstring
* feat: introduce FileSearchBackend abstraction for cross-client support
Replace direct OpenAI client usage with FileSearchBackend ABC:
- OpenAIFileSearchBackend: for OpenAIChatClient (Responses API)
- FoundryFileSearchBackend: for FoundryChatClient (Azure Foundry)
- Shared base _OpenAICompatBackend for common vector store CRUD
FileSearchConfig now takes a backend instead of openai_client.
Factory methods from_openai() and from_foundry() for convenience.
BREAKING: FileSearchConfig(openai_client=...) -> FileSearchConfig.from_openai(...)
* refactor: FileSearchBackend abstraction + caller-owned vector store
* fix: file_search reliability and sample improvements
- Poll vector store indexing (create_and_poll) to ensure file_search
returns results immediately after upload
- Set status to failed when vector store upload fails
- Skip get_analyzed_document tool in file_search mode to prevent
LLM from bypassing RAG
- Simplify sample auth: single credential, direct parameters
- Use from_foundry backend for Foundry project endpoints
* perf: set max_num_results=10 for file_search to reduce token usage
* fix: move import to top of file (E402 lint)
* chore: remove unused imports
* fix: align azure-ai-contentunderstanding with MAF coding conventions
- Add module-level docstrings to __init__.py and _context_provider.py
- Use Self return type for __aenter__ (with typing_extensions fallback)
- Use explicit typed params for __aexit__ signature
- Add sync TokenCredential to AzureCredentialTypes union
- Pass AGENT_FRAMEWORK_USER_AGENT to ContentUnderstandingClient
- Remove unused ContentLimits from public API and tests
- Fix FileSearchConfig tests to match refactored backend API
- Fix lifecycle tests to match eager client initialization
* refactor: improve CU context provider API surface and fix CI
- Refactor _analyze_file to return DocumentEntry instead of mutating dict
- Remove TokenCredential from AzureCredentialTypes (fixes mypy/pyright CI)
- Remove OpenAIFileSearchBackend/FoundryFileSearchBackend from public API
(internal to FileSearchConfig factory methods)
- Remove DocumentStatus from public exports (implementation detail)
- Update file_search comments to reflect backend-agnostic design
- Add DocumentStatus enum, analysis/upload duration tracking
- Add combined timeout for CU analysis + vector store upload
* fix: improve file_search samples and move tool guidelines to context provider
- Delete redundant devui_file_search_agent sample (duplicate of azure_openai variant)
- Move tool usage guidelines from sample agent instructions into context provider
(extend_instructions in step 6, applied automatically for all file_search users)
- Fix file_search purpose: use from_foundry() for Azure OpenAI (purpose="assistants")
- Add filename hint in upload instructions for targeted file_search queries
- Reduce max_num_results from 10 to 3 in both devui samples
- Simplify agent instructions in both samples (remove tool-specific guidance)
* feat: improve source_id, integration tests, and content assertions
- Rename DEFAULT_SOURCE_ID to "azure_ai_contentunderstanding" (matches
azure_ai_search convention)
- Improve source_id docstring to describe default value
- Clarify _detect_and_strip_files docstring (CU-supported files)
- Add invoice.pdf test fixture from Azure CU samples repo
- Refactor integration tests to use invoice.pdf directly (assert instead
of skip when fixture missing)
- Add URI content test (Content.from_uri with external URL)
- Add "CONTOSO LTD." content assertion to all integration tests
- Use max_wait=None in integration tests (wait until complete)
* feat: reject duplicate filenames, add integration tests and sample comments
- Reject duplicate document keys in before_run (skip + warn LLM to rename)
- Update _derive_doc_key docstring to document uniqueness constraint
- Add unit tests for duplicate filename rejection (cross-turn and same-turn)
- Add integration test for data URI content (from_uri with base64)
- Add integration test for background analysis (max_wait timeout + resolve)
- Add filename recommendation comments to all samples' Content.from_data()
* chore: improve doc key derivation, comments, and README
- Replace hash-based doc key with uuid4 for anonymous uploads (O(1), no payload traversal)
- Remove hashlib import (no longer needed)
- Add File Naming section to README (filename importance, duplicate rejection)
- Improve inline comments (_derive_doc_key, _extract_binary, URL parsing)
* test: strengthen _format_result assertions with exact expected strings
- Replace loose 'in' checks with exact 'assert formatted == expected'
for both multi-segment and single-segment format tests
- Add object-type fields (ShippingAddress, Speakers) to test data
to cover nested dict/list serialization
- Add position-based ordering assertions to verify structural
correctness (header -> markdown -> fields across segments)
* refactor: move invoice.pdf to shared sample_assets directory
- Move invoice.pdf from tests/cu/test_data/ to
python/samples/shared/sample_assets/ as single source of truth
- Add INVOICE_PDF_PATH constant in test_integration.py pointing
to the shared location
- Update document_qa.py, invoice_processing.py, large_doc_file_search.py
to use invoice.pdf instead of sample.pdf
* refactor: reorganize samples into numbered dirs and simplify auth
- Move script samples into 01-get-started/ with numbered prefixes
(01_document_qa, 02_multimodal_chat, 03_invoice_processing,
04_large_doc_file_search)
- Move devui samples into 02-devui/ with 01-multimodal_agent and
02-file_search_agent/{azure_openai_backend,foundry_backend}
- Move invoice.pdf to CU package-local samples/shared/sample_assets/
- Replace kwargs dicts with direct constructor calls; support both
API key (AZURE_OPENAI_API_KEY) and AzureCliCredential
- Update README sample table with new paths
* fix: resolve CI lint errors (D205, RUF001, E501)
- Fix D205: single-line docstring summary for _detect_and_strip_files
- Fix RUF001: replace EN DASH with HYPHEN-MINUS in segment headers
- Fix E501: wrap long assertion lines in tests
- Also includes samples reorg and auth simplification
* refactor: overhaul samples — FoundryChatClient, sessions, remove get_analyzed_document
Samples:
- Switch all samples from deprecated AzureOpenAIResponsesClient to FoundryChatClient
- Add 02_multi_turn_session.py showing AgentSession persistence across turns
- Rewrite 03_multimodal_chat.py with real PDF + audio + video (parallel
analysis), per-modality follow-ups, cross-document question, elapsed
time, user prompts, and input token counts
- Renumber: 02->03 multimodal, 03->04 invoice, 04->05 file_search
Context provider:
- Remove get_analyzed_document tool -- full content is in conversation
history via InMemoryHistoryProvider, no retrieval tool needed
- Remove follow-up turn instructions about tools
- Only list_documents tool remains (for status queries)
- Update README to reflect tool removal
* feat: add 05_background_analysis sample and fix 04 session/max_wait

* docs: rewrite README — concise format, prerequisites, CU link
* fix: resolve pyright errors in _format_result segment cast
* docs: add numbered section comments and fresh sample output to all samples
- Add numbered section comments (# 1. ..., # 2. ...) per SAMPLE_GUIDELINES
- Re-run all 6 samples and update expected output with real results
- Fix duplicate sample output blocks in 04 and 05
- Update README code example to use public invoice URL
* feat: add load_settings support for env var configuration
- Make endpoint optional in constructor — auto-loads from
AZURE_CONTENTUNDERSTANDING_ENDPOINT env var via load_settings()

pages, words, lines, paragraphs, sections, spans, and source
fields that are not used by any unit test.
- Add docstring note that filename must be unique within a session;
duplicate filenames are rejected and the file will not be analyzed.

* Fix AGENTS.md to match implementation; remove unused variable in test helper
AGENTS.md:
- Remove _ensure_initialized() reference (client is created in __init__)
- Fix multi-segment docs: segments kept as list, not merged into fields
- Remove get_analyzed_document() reference (only list_documents registered)
- Update sample names to match current directory structure
test_context_provider.py:
- Simplify _make_data_uri() — remove unused 'encoded' variable
* Fix premature file_search instruction for background-completed docs
- Change _resolve_pending_tasks() instruction from 'Use file_search'
to 'being indexed' since the upload hasn't completed yet at that point.
- Add LLM instruction on upload failure in step 1b so the agent can
inform the user the document isn't searchable.
* fix: wrap long line in devui agent instructions (E501)
* Fix Copilot review: unused logger, stray code in README, await cancelled tasks
- _file_search.py: Remove unused logger and logging import
- 01-multimodal_agent/README.md: Remove accidentally pasted Python script
- _context_provider.py close(): Await cancelled tasks before closing
client to prevent 'Task destroyed but pending' warnings
* Sanitize doc keys and fix duplicate filename re-injection
- Add _sanitize_doc_key() to strip control characters, collapse
whitespace, and cap length at 255 chars — prevents prompt injection
via crafted filenames in extend_instructions() calls.
- Track accepted doc_keys in step 3 so step 5 only injects content
for files actually analyzed this turn, not pre-existing duplicates.
- Soften duplicate upload instruction wording (remove IMPORTANT/caps).
* fix: add type annotation to tasks_to_cancel for pyright
* Move per-session mutable state to state dict for session isolation
Previously _pending_tasks, _pending_uploads, and _uploaded_file_ids
were stored on self, shared across all sessions. This caused
cross-session leakage: Session A's background task results could be
injected into Session B's context.
Now these are stored in the per-session state dict. Global copies
(_all_pending_tasks, _all_uploaded_file_ids) are kept on self only
for best-effort cleanup in close().
Add 2 new TestSessionIsolation tests verifying that background tasks
and resolved content stay within their originating session.
* Remove unused AnalysisSection enum values
Only MARKDOWN and FIELDS are handled by _extract_sections().
Remove FIELD_GROUNDING, TABLES, PARAGRAPHS, SECTIONS to avoid
exposing dead options to users.
* Recursively flatten object/array field values for cleaner LLM output
- Use SDK .value property with recursive extraction for object/array fields
- Object: AmountDue -> {Amount: 610, CurrencyCode: USD} (was raw SDK dict)
- Array: LineItems -> list of flattened items (was raw SDK list)
- Update invoice fixture with object/array fields from prebuilt-invoice
- Add 3 unit tests for object, array, and nested object field extraction
* Preserve sub-field confidence; compare full expected JSON in tests
* Remove incorrect MIME aliases (audio/mp4, video/x-matroska)
* feat: add AnalysisInput, content_range, warnings, and category support
- Use SDK AnalysisInput model instead of raw body dict for begin_analyze
- Forward content_range from additional_properties to CU (page/time ranges)
- Extract CU warnings with code/message/target (ODataV4Format) into output
- Include content-level category from classifier analyzers
- Add 5 new tests: warnings, category, content_range forwarding
- Fix pyright with explicit casts; fix en-dash lint (RUF002)
* fix: falsy-0 bug in duration calc; improve test coverage
- Fix start_time_ms=0 treated as falsy by 'or' short-circuit, use
'is None' checks instead for duration and segment time extraction
- Update warnings test to use RAI ContentFiltered codes
- Enrich warnings extraction to include code/message/target (ODataV4Format)
- Add multi-segment video category test with per-segment assertions
* refactor: split _context_provider.py into focused modules
- Extract _constants.py: SUPPORTED_MEDIA_TYPES, MIME_ALIASES, analyzer maps
- Extract _detection.py: file detection, MIME sniffing, doc key derivation
- Extract _extraction.py: result extraction, field flattening, LLM formatting
- _context_provider.py delegates via thin wrappers (793 lines, was 1255)
- Update test imports to use _constants.py for SUPPORTED_MEDIA_TYPES
* docs: update AGENTS.md with DocumentStatus, FileSearchBackend, and _file_search.py
* refactor: replace AnalysisSection enum with Literal type for simpler DX
- Remove AnalysisSection(str, Enum) class, replace with Literal["markdown", "fields"] type alias
- Users can now pass plain strings: output_sections=["markdown"] — no extra import needed
- AnalysisSection type alias still exported for type annotation use
- Update all samples, tests, and internal code to use string literals
- Address PR review feedback (eavanvalkenburg)
* refactor: replace asyncio.Task with continuation tokens for serializable state
- Replace state["_pending_tasks"] (asyncio.Task — not serializable) with
state["_pending_tokens"] (dict of continuation token strings) so the
framework can persist session state to disk/storage
- Resume pending analyses via Azure SDK continuation_token mechanism
- Fix: resumed pollers have stale cached status (done() always False),
use asyncio.wait_for(poller.result()) with 10s min timeout instead
- Remove _background_poll(), _all_pending_tasks, and task cancellation
- Address PR review feedback (eavanvalkenburg): state must be serializable
* fix: resolve CI lint (RUF052) and mypy (call-overload) errors
* feat: add structured output (Pydantic model) to invoice processing sample
- Use response_format=InvoiceResult for schema-constrained LLM output
- Use output_sections=["fields"] only (no markdown needed for structured output)
- Add LowConfidenceField model with confidence values
- Add comments about prebuilt-invoice extensive schema vs simplified model
- Address PR review feedback (eavanvalkenburg): use structured response
* fix: use FOUNDRY_PROJECT_ENDPOINT and FOUNDRY_MODEL env vars in all samples
Replace AZURE_AI_PROJECT_ENDPOINT → FOUNDRY_PROJECT_ENDPOINT and
AZURE_OPENAI_DEPLOYMENT_NAME → FOUNDRY_MODEL across all sample .py and
README.md files. Address PR review feedback (eavanvalkenburg).
* refactor: remove background_analysis sample, use FoundryChatClient in DevUI
- Remove 05_background_analysis.py (per reviewer feedback — discuss max_wait
design separately from samples)
- Renumber 06_large_doc_file_search.py → 05_large_doc_file_search.py
- Replace AzureOpenAIResponsesClient with FoundryChatClient in all DevUI samples
- Replace client.as_agent() with Agent(client=client, ...) everywhere
- Add max_wait comments explaining interactive vs batch usage
- Update README.md and AGENTS.md
- Address PR review feedback (eavanvalkenburg)
* fix: vector_stores API moved from beta namespace in OpenAI SDK
* docs: add comments about multi-file support and CU service limits in file_search sample
* fix: broken markdown links after sample removal and renumbering
* fix: migrate BaseContextProvider to ContextProvider (non-deprecated)
* fix: Message(text=) -> Message(contents=[]) for API compatibility
* Inline _constants.py into consuming modules
Remove _constants.py and move constants to where they are used:
- SUPPORTED_MEDIA_TYPES, MIME_ALIASES → _detection.py
- MEDIA_TYPE_ANALYZER_MAP, DEFAULT_ANALYZER → _context_provider.py
Addresses review feedback to reduce file count.
* Mark package as alpha per package management skill
- Version: 1.0.0b260401 → 1.0.0a260401
- Classifier: Development Status 4 - Beta → 3 - Alpha
- Add to PACKAGE_STATUS.md as alpha
Follows the alpha package checklist from python-package-management skill.
* Replace extend_instructions with extend_messages for status notifications
Status/error/result notifications now use extend_messages (conversation
context) instead of extend_instructions (system prompt). This avoids
system prompt bloat and keeps behavioral directives separate from
event notifications.
- 11 extend_instructions calls → extend_messages (role='user')
- 1 extend_instructions retained: tool usage guidelines (behavioral)
- 6 test assertions updated to check context_messages
All 84 unit tests + 5 live integration tests pass.
* Fix lint: E402 import order, ISC004 implicit string concatenation
- Move constants after all imports to fix E402
- Wrap multi-line strings in parentheses inside contents=[] to fix ISC004
* Fix lint: remove unused json import in invoice sample
* Fix CI: apply ruff format + fix E501 line length after reformatting
ruff format expands Message() calls to multi-line, pushing string
indentation deeper. Break long strings to fit within 120 char limit
after formatting. Also removes unused json import in sample.
* Address review feedback: keyword-only args, accept pre-built client, remove wrappers
- All __init__ args now keyword-only (matches FoundryChatClient pattern)
- New 'client' param accepts pre-built ContentUnderstandingClient
- core dep bound: >=1.0.0rc5 → >=1.0.0,<2
- Self import moved after local imports
- Removed 9 static method wrappers; callsites use module functions directly
- Tests updated to import derive_doc_key and format_result directly
* fix: remove duplicate ContentUnderstandingClient instantiation
The client was being created twice — once inside the if/else block and
again unconditionally after it. The second instantiation overwrote the
pre-built client path and failed type checking when credential was None.
* rename: azure-ai-contentunderstanding → azure-contentunderstanding
Package: agent-framework-azure-ai-contentunderstanding → agent-framework-azure-contentunderstanding
Module: agent_framework_azure_ai_contentunderstanding → agent_framework_azure_contentunderstanding
Directory: packages/azure-ai-contentunderstanding → packages/azure-contentunderstanding
Per agreement with PM and MAF team to drop 'AI' from the package name.
* feat: add ContentUnderstanding re-export to agent_framework.foundry namespace
Enables: from agent_framework.foundry import ContentUnderstandingContextProvider
Exports: ContentUnderstandingContextProvider, FileSearchConfig,
FileSearchBackend, AnalysisSection, DocumentStatus
Updates all samples and README to use the foundry namespace import.
* fix: add missing copyright headers to standalone sample scripts
* chore: remove .vscode/settings.json and add to .gitignore
* refactor: reuse FoundryChatClient.client for vector store ops in file_search sample
Address review feedback from TaoChenOSU:
- 05_large_doc_file_search.py: use client.client instead of manually
constructing AsyncAzureOpenAI; remove openai dependency
- azure_openai_backend/agent.py: import reorder only (AIProjectClient
kept — required for sync vector store creation in DevUI)
* fix: skip closing client when caller passes pre-built client
When a ContentUnderstandingClient is passed via client=, the caller
owns its lifecycle. Added _owns_client flag so close() only closes
the client when we created it internally.

* Python: bump package versions for 1.2.1 release
PATCH bump (1.2.0 -> 1.2.1) for the released cohort. The release window
covers two PRs, no new public APIs:
- agent-framework-core: prevent inner_exception from being lost in
AgentFrameworkException (#5167)
- samples: add requirements.txt and .env.example to the a2a/ hosting
sample for pip-based setup (#5510)
Per lockstep convention, all 21 beta packages stamp 1.0.0b260428 and all
3 alpha packages stamp 1.0.0a260428, regardless of per-package code
churn. Every non-core package floor on agent-framework-core is raised to
>=1.2.1 to keep cohort signaling consistent. Date stamp reflects the
local (Asia) cut date 2026-04-28.
* Python: silence pyright unknown-type warnings in hosted-env detection
`azure.ai.agentserver.core` is probed at runtime via `importlib.util.find_spec`
and is not a declared dependency. The existing `# pyright: ignore[reportMissingImports]`
suppresses the missing-import warning, but at `lowest-direct` resolution pyright
still reports the imported symbol (`AgentConfig`) and its members (`from_env`,
`is_hosted`) as unknown, breaking `validate-dependency-bounds-test` for
`packages/core`.
Extend the existing ignore to cover `reportUnknownVariableType` on the import
and `reportUnknownMemberType` on the call site so the bounds check returns to
green. Behavior is unchanged.
Latent since #5455 (shipped in 1.2.0).
* Python: raise agent-framework-gemini lower bound to google-genai>=1.65.0
The Gemini chat client references several `google.genai.types` symbols
(`FileSearch`, `ThinkingLevel`, `SearchTypes`, `McpServer`,
`StreamableHttpTransport`, plus call-site keyword args `mcp_servers` and
`search_types`) that are not present at the lower bound of `google-genai>=1.0.0`.
At `lowest-direct` resolution this caused `validate-dependency-bounds-test` to
fail for `packages/gemini` with eleven `reportAttributeAccessIssue` /
`reportUnknownVariableType` errors.
Walking the upstream `google.genai.types` API:
- `GoogleMaps`, `AuthConfig`: present from 1.40.0
- `FileSearch`: introduced in 1.49.0
- `ThinkingLevel`: introduced in 1.55.0
- `SearchTypes`, `McpServer`, `StreamableHttpTransport`: introduced in 1.65.0
Bump the lower bound to 1.65.0 — the minimum version that exposes every symbol
the package actually uses. Keep the `<2.0.0` upper cap unchanged. With this
bump `validate-dependency-bounds-test` passes for both lower and upper
resolution scenarios across all 27 workspace packages.
Latent since #4847 (Gemini package introduction in 1.1.0); aggravated by
subsequent feature additions that pulled in newer `types.*` symbols.
* Python: add dependabot bumps to 1.2.1 CHANGELOG
Catalog the 15 dependabot dependency updates that merged on `upstream/main`
between python-1.2.0 and the 1.2.1 cut window under a new Changed section:
- Workspace dev/runtime deps: `rich`, `prek`, `python-multipart`, `pyasn1`,
`pytest` (ag-ui, devui, lab), `uv` (lab)
- Frontend deps: `vite` (devui, chatkit), `postcss` (devui, chatkit, handoff),
`picomatch` (devui, handoff)
CHANGELOG-only — no source or pyproject.toml changes. PRs themselves merged
upstream independently of this release branch and will be brought in via the
PR merge.
* Add requirements.txt and .env.example to a2a sample
Beginners following the a2a/ sample had no pip-based install path:
the directory lacked requirements.txt and .env.example, unlike every
other 04-hosting/ sample.
- Add requirements.txt with editable local package paths matching the
pattern used in azure_functions/ and similar hosting samples
- Add .env.example documenting FOUNDRY_PROJECT_ENDPOINT, FOUNDRY_MODEL,
and A2A_AGENT_HOST
- Update README Quick Start to cover both pip (.venv) and uv workflows

to avoid contradicting the 'run from this directory' instruction
- Fix A2A_AGENT_HOST default in .env.example from 5001 to 5000 to match
function-tools flow; add clarifying comments about port usage

* fix: prevent inner_exception from being lost in AgentFrameworkException
The __init__ method unconditionally called super().__init__() after
the conditional call with inner_exception, effectively overwriting the
exception args and losing the inner_exception reference.
Add else branch so super().__init__() is only called once with the
correct arguments.
Fixes#5155

- test_exception_with_inner_exception: verifies args include inner exception
- test_exception_without_inner_exception: verifies args only contain message
- test_exception_inner_exception_none_explicit: verifies explicit None
Covers both branches of the if/else in __init__.

* Address PR review feedback.
- Return 404 Not Found when no orchestration with the given ID exists
- Return 200 OK for failed workflows (the HTTP operation succeeded;
the workflow outcome is conveyed via the response body)
- Rename 'status' to 'workflowStatus' in WorkflowRunResponse to avoid
inconsistency with AgentRunSuccessResponse which uses integer status
- Add optional 'error' field (omitted from JSON when null) to

* Bump Python package versions for 1.2.0 release
Released tier bumps 1.1.1 -> 1.2.0 (core, openai, foundry, root) to
reflect additive public APIs landed since 1.1.0: functional workflow API
(#4238) and FunctionTool SKIP_PARSING sentinel (#5424). All beta packages
stamped 1.0.0b260424, alpha packages 1.0.0a260424. All 26 non-core
agent-framework-core floors raised to >=1.2.0,<2. CHANGELOG consolidates
the never-tagged 1.1.1 entries with the post-merge additions into [1.2.0].
* Update CHANGELOG footer links for 1.2.0
Advance [Unreleased] comparison base from python-1.1.0 to python-1.2.0
and add a [1.2.0] reference link comparing python-1.1.0...python-1.2.0
so the heading links resolve correctly.
* Fix CHANGELOG: restore [1.1.1] section and add proper [1.2.0]
Previous commit incorrectly renamed the [1.1.1] header to [1.2.0], which
wiped the historical 1.1.1 entries and wrongly attributed them to 1.2.0.
This restores [1.1.1] to its origin/main content and adds a new [1.2.0]
section above containing only the commits in python-1.1.1..HEAD:
- #4238 functional workflow API
- #5142 GitHub Copilot OpenTelemetry
- #2403 A2A bridge support
- #5070 oauth_consent_request events in Foundry clients
- #5447 FoundryAgent hosted agent sessions
- #5459 hosting server dependency upgrade + types
- #5389 AG-UI reasoning/multimodal parsing fix
- #5440 stop [TOOLBOXES] warning spam
- #5455 user agent prefix fix
Also corrects the [1.2.0] compare base to python-1.1.1 (not 1.1.0) and
adds the missing [1.1.1] reference link.
* Fix Foundry clients not surfacing oauth_consent_request events (#5054)
Override _parse_chunk_from_openai in both RawFoundryChatClient and
RawFoundryAgentChatClient to intercept response.output_item.added
events with item.type == 'oauth_consent_request'. The consent link
is validated (HTTPS required) and converted to
Content.from_oauth_consent_request, which the AG-UI layer already
knows how to emit as a CUSTOM event.

* Address PR review feedback for #5054 OAuth consent parsing
- Extract shared helper (try_parse_oauth_consent_event) to avoid
duplicated logic between RawFoundryChatClient and
RawFoundryAgentChatClient
- Use urllib.parse.urlparse() for HTTPS validation instead of
case-sensitive startswith check
- Sanitize log messages to avoid leaking consent_link tokens;
log only item id
- Add model=self.model to ChatResponseUpdate to match parent behavior
- Add assertions on role, raw_representation, and model in happy-path
tests
- Add test for empty-string consent_link
- Add test verifying non-oauth events delegate to super()

* Handle response.oauth_consent_requested top-level event (#5054)
Add support for the top-level response.oauth_consent_requested stream
event in addition to the response.output_item.added variant. The

reliably surfaced.
Extract _validate_consent_link helper within _oauth_helpers.py to
reduce nesting.

* Fix pyright type errors
* Address PR review comments on functional workflow API
1. Allow request_info inside @step: Auto-inject RunContext into step
functions that declare a RunContext parameter (by type or name 'ctx'),
and expose get_run_context() for programmatic access.
2. Handle None responses: Log a warning when a response value is None,
and document the behavior in request_info docstring.
3. Add executor_bypassed event type: Replace executor_invoked +
executor_completed with a single executor_bypassed event when a step
replays from cache, making cached vs live execution explicit.

* Add regression tests for PR review comments on functional workflow API
The three review comments (request_info in @step, None response handling,
executor_bypassed event type) were already addressed in 7da7db4e. This
commit adds cross-cutting regression tests that exercise the interactions
between these features:
- HITL in step with caching: preceding step bypassed on resume
- Full checkpoint lifecycle with HITL step (interrupt -> resume -> restore)
- None response inside step-level request_info logs warning
- WorkflowInterrupted from step does not emit executor_failed

* Address PR #4238 review comments on functional workflow API
Comment 1 (request_info in @step): Already supported. Added comment in
StepWrapper.__call__ explaining why WorkflowInterrupted (BaseException)
safely bypasses the except Exception handler.
Comment 2 (None response): Added docstring to _get_response clarifying
the (found, value) return tuple semantics and None handling.
Comment 3 (bypass event type): executor_bypassed is already a dedicated
event type in WorkflowEventType. Updated comment at the bypass site to
make the deliberate event type choice explicit.

* Add experimental API warnings to functional workflow module
Mark all public classes and decorators (workflow, step, RunContext,
FunctionalWorkflow, StepWrapper, FunctionalWorkflowAgent) as
experimental and subject to change or removal.
* Address PR #4238 review comments from @eavanvalkenburg
- RunContext docstring leads with purpose (opt-in handle for HITL,
custom events, state) so readers importing it from the public surface
understand its role before the mechanics (#2993513452).
- Rename `06_first_functional_workflow.py` to
`06_functional_workflow_basics.py`; the previous filename was
confusing since it followed `05_functional_workflow_with_agents.py`
(#2993531979).
- Simplify `05_functional_workflow_with_agents.py` to call agents
directly without a @step wrapper; the step-vs-no-step contrast lives
in `03-workflows/functional/agent_integration.py`, keeping the
get-started sample minimal (#2993525532).
- Switch functional samples to `FoundryChatClient` for consistency with
the rest of 01-get-started and 03-workflows (follow-up on #2876988570).
- Use walrus in `hitl_review.py` final-state assertion (#2993572182).
- Add expected-output block to `basic_streaming_pipeline.py` (#2993557609).
- Clarify in `parallel_pipeline.py` that `@step` composes with
`asyncio.gather` (#2993597282).
- `naive_group_chat.py` threads `list[Message]` between turns instead
of stringifying the transcript, preserving role/authorship (#2993583231).
Drive-by: pre-commit hook sorts an unrelated import block in
`samples/04-hosting/foundry-hosted-agents/responses/02_local_tools/main.py`.
* Fix 10 functional-workflow API bugs from /ultrareview pass
- bug_001: `ctx.request_info()` without an explicit `request_id` now derives
a deterministic `auto::<index>` id from the call-counter, so HITL resume
works correctly on the documented default path. A uuid was regenerated on
every replay, making resume impossible.
- bug_002: `StepWrapper.__call__` no longer deepcopies arguments on the
cache-hit replay branch. The copy is only performed on the live-execution
path (for the event log) and falls back to the original mapping if deepcopy
fails, so steps whose args aren't deepcopyable (locks, sockets, sessions)
can still resume from checkpoint.
- bug_007: `_set_responses` now prunes each resolved `request_id` from
`_pending_requests`, and the cache-hit branch in `request_info` does the
same. Previously, answered requests were re-serialized into every
subsequent checkpoint and the final checkpoint falsely claimed pending
requests even after the workflow completed.
- bug_008: `_compute_signature_hash` now mixes the function's `co_code` and
`co_names` into the checkpoint signature, so changes to the workflow body
invalidate older checkpoints even when steps are accessed via module /
class attributes (which `_discover_step_names` can't see statically).
`RunContext._record_observed_step` records observed step names for
diagnostics.
- bug_010: `FunctionalWorkflow.run()` docstring corrected — says "at least
one of message/responses/checkpoint_id" and explicitly notes `responses`
may be combined with `checkpoint_id` (the validator already allowed this).
- bug_013: `FunctionalWorkflowAgent` now surfaces `request_info` events as
`FunctionApprovalRequestContent` items (mirroring graph `WorkflowAgent`),
threads `responses=` and `checkpoint_id=` through to the underlying
workflow, and exposes `pending_requests`. Previously `.as_agent()`
returned empty `AgentResponse` for HITL workflows — effectively unusable.
- bug_014: `FunctionalWorkflow` now clears `_last_message`,
`_last_step_cache`, and `_last_pending_request_ids` on clean completion.
`run()` validates that `responses=` keys intersect the currently-pending
request set (or raises with a clear error) instead of silently replaying
against stale singleton state from a prior run.
- bug_015: `FunctionalWorkflow.as_agent` signature now matches graph
`Workflow.as_agent`: accepts `name`, `description`, `context_providers`,
and `**kwargs`. `FunctionalWorkflowAgent` stores the overrides.
- bug_017: `RunContext.set_state` raises `ValueError` for underscore-
prefixed keys (the framework's `_step_cache` / `_original_message` keys
would silently clobber user state on checkpoint save and user
underscore-prefixed state was dropped on restore). Docstring documents
the reserved prefix.
- merged_bug_003: Workflow function arity is validated at decoration time.
Multiple non-ctx parameters raise `ValueError` immediately (previously
every arg past the first was silently dropped at call time). Passing a
non-None `message` to a ctx-only workflow raises `ValueError` instead of
silently discarding the message.
Test coverage: +18 regression tests covering every fix. Full workflow
suite now 766 passed, 1 skipped, 2 xfailed; full core suite 2338 passed.
* Deslop functional.py fix commit
- Remove dead instrumentation added in the prior commit that was never
consumed: `RunContext._observed_step_names`,
`RunContext._record_observed_step`, `FunctionalWorkflow._runtime_step_names`,
and `FunctionalWorkflowAgent._extra_kwargs`. The signature hash relies on
`co_code` alone, which covers the attribute-access case without the
collection-scaffolding.
- Trim over-explanatory comments that restated what the code does or what
it no longer does. Keep only the comments that answer "why" for the
non-obvious bits (deterministic id contract, defensive deepcopy, stale
replay guard).
- Compress the `_compute_signature_hash` and FunctionalWorkflow `__init__`
block docstrings without losing the user-facing reasoning.
Net -49 lines. Regression lock preserved (766 passed, 1 skipped, 2 xfailed).

* Python: Add OpenTelemetry integration for GitHubCopilotAgent
- Split GitHubCopilotAgent into RawGitHubCopilotAgent (core, no OTel) and
GitHubCopilotAgent(AgentTelemetryLayer, RawGitHubCopilotAgent) with tracing
- Add default_options property to expose model for span attributes
- Export RawGitHubCopilotAgent from all public namespaces
- Add github_copilot_with_observability.py sample and update README
* Python: Fix OTEL_SERVICE_NAME default in GitHub Copilot README
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* Python: Add unit tests for RawGitHubCopilotAgent.default_options property
* Python: Address review feedback on GitHubCopilotAgent OTel integration
- Add middleware param to GitHubCopilotAgent.run() overloads so per-call
middleware is explicitly forwarded through AgentTelemetryLayer
- Remove github_copilot_with_observability.py sample per feedback; replace
with inline snippet + link to observability samples in README
* Python: Address review feedback on log_level and session kwargs typing
- Add middleware param to RawGitHubCopilotAgent.run() overloads for interface
compatibility with AgentTelemetryLayer
- Fix import in README observability snippet to use agent_framework.github
* Python: Add AgentMiddlewareLayer to GitHubCopilotAgent MRO
Follow FoundryAgent pattern: AgentMiddlewareLayer runs outside the telemetry
span so middleware execution time is not captured in traces. Overloads removed
as AgentMiddlewareLayer.run() handles dispatch via MRO.
* Python: Add explicit __init__ to GitHubCopilotAgent for auto-complete and docstrings
* Python: Address review feedback on middleware warning and test assertions
- Add assert "timeout" not in opts to test_default_options_includes_model_for_telemetry
to document the intentional asymmetry where timeout is extracted into _settings
and not returned in default_options.
- Replace silent del middleware with a logged warning when per-run middleware is
passed to RawGitHubCopilotAgent, making it clear that the GitHub Copilot SDK
handles tool execution internally and chat/function middleware cannot be injected.
* Python: Use Self for __aenter__ return type in RawGitHubCopilotAgent
Address review feedback: use typing.Self (3.11+) / typing_extensions.Self
(3.10) for __aenter__ so subclasses like GitHubCopilotAgent get the correct
return type from async context manager usage.

* Fix AG-UI reasoning role and multimodal media value field parsing
Fix two spec compliance issues in the AG-UI integration:
1. ReasoningMessageStartEvent now uses role='reasoning' instead of
role='assistant', matching the AG-UI specification for reasoning
messages.
2. _parse_multimodal_media_part now reads the 'value' field from source
dicts (with fallback to 'data' for backward compatibility), matching
the current AG-UI InputContentSource specification.
Bump ag-ui-protocol dependency from ==0.1.13 to >=0.1.16,<0.2 to pick
up the SDK fix that accepts role='reasoning' in ReasoningMessageStartEvent.
Fix pre-existing pyright reportMissingImports errors for orjson in sample
files, and fix import ordering in foundry-hosted-agents sample.

Address PR review feedback: the .maf-runtime-ready file is not referenced anywhere in the repo and was left over from automation.
Fixes#5340
* Python: Fix duplicate AG-UI multimodal 'value' parsing in snapshot path
The snapshot normalization path used a second copy of the multimodal source
parsing logic that still read the deprecated 'data' field. When clients sent
base64 media with source={"type": "base64", "value": ...}, the snapshot event
emitted by the server dropped the payload, causing AG-UI-compatible clients
to crash on ingest.
Extract the shared source-field extraction into _extract_multimodal_source_fields
so both _parse_multimodal_media_part and the snapshot _legacy_binary_part stay
in sync with the AG-UI spec. Add snapshot-path regression tests covering
value-only, value-preferred-over-data, and the legacy data-field fallback.
Addresses review feedback on #5389 from @Rickyneer.

* Python: Foundry: make response tool sanitizer internal, drop TOOLBOXES warning
sanitize_foundry_response_tool runs on every tool passed to the Foundry
Responses API, so its @experimental(TOOLBOXES) decorator was emitting a
[TOOLBOXES] ExperimentalWarning for any FoundryChatClient call, even when
no toolbox was involved. The function isn't in __all__ and has no external
callers. Rename to _sanitize_foundry_response_tool and drop the decorator;
the actual toolbox-facing public helpers remain gated.

Scopes the triage job to the integration GitHub Environment, adds
the azure/login OIDC step, and exposes the same OpenAI / Azure
OpenAI / Foundry / Anthropic env vars the integration test
workflow uses. This lets the triage agent write repro code that
constructs model clients from the environment without any secrets
entering the agent prompt or generated-code literals.
Azure OpenAI and Foundry continue to authenticate via AAD
(DefaultAzureCredential), so there is no API key to leak for
those providers.
* Automated issue triage workflow
* Bump dependencies
* Fix issue-triage workflow: security, reliability, and testability
Address six review comments on the issue-triage workflow:
1. Change trigger from issues:opened to issues:labeled so the
secret-backed triage flow is only triggered by a maintainer-
controlled signal.
2. Include inputs.issue_number in the concurrency group so
workflow_dispatch runs for the same issue are properly
de-duplicated.
3. Improve team membership error handling to fail closed: verify
the team exists before checking membership, and only treat a
404 as 'not a member' (all other errors fail the job).
4. Use optional chaining (issue.user?.login) for the API-fetched
issue to handle deleted GitHub accounts without crashing.
5. Extract the inline github-script into a testable module at
.github/scripts/check_team_membership.js with 10 tests in
.github/tests/test_check_team_membership.js covering all
code paths (payload/API author resolution, deleted accounts,
team lookup failure, 404 vs non-404 membership errors).
6. Make the spam gate actually stop the job by exiting non-zero
instead of just logging, so future steps cannot accidentally
run for spam issues.

* improved parsing of tool call results and tweaks
* Address PR review: skip_parsing flag, broader registry close, comment fix
- FunctionTool.invoke now takes a boolean skip_parsing flag instead of the
SKIP_PARSING sentinel; the sentinel is still accepted as result_parser at
construction time to opt out of parsing for every call. The two paths are
equivalent.
- _SandboxRegistry.close now invokes any sandbox close/shutdown hook on the
entry's own worker thread (PyO3 unsendable), then shuts the worker down,
then cleans up the per-entry temporary directories.
- Clarified the _SandboxWorker.shutdown comment to describe the actual
ThreadPoolExecutor.shutdown(wait=False, cancel_futures=False) semantics.
- Hyperlight host callback uses skip_parsing=True (the new flag).

Add three tests to A2AServerServiceCollectionExtensionsTests that verify
custom keyed services are actually wired through to the A2AServer, not
just that the server resolves non-null:
- Custom IAgentHandler: verifies the keyed handler is invoked when
processing a SendMessageRequest instead of the default A2AAgentHandler.
- Custom AgentSessionStore (no handler): verifies the keyed session
store's GetSessionAsync is called during request processing when no
custom handler is registered.
- Default stores end-to-end: verifies the InMemoryAgentSessionStore and
InMemoryTaskStore defaults successfully process a request. Uses a new
CreateAgentMockForRequests helper that includes SerializeSessionCoreAsync
setup needed by InMemoryAgentSessionStore.
All tests call A2AServer.SendMessageAsync directly (no HTTP layer needed)
and use CancellationToken timeouts to guard against hangs.

* Bump Python version for a release.
* Revert lockstep bumps on unchanged connectors
Per PR review: only connectors that changed (or whose published metadata
changed) should get new versions. Keeps released tier at 1.1.1, a2a/ag-ui
at 1.0.0b260422, foundry-hosting at 1.0.0a260422; reverts the 19 unchanged
betas and 2 unchanged alphas to 1.0.0b260421/1.0.0a260421. Reverts all 26
non-core agent-framework-core floors to >=1.1.0,<2 since no connector
actually depends on a 1.1.1 API or bug fix.
* Restore lockstep prerelease bumps and raise core floors to >=1.1.1
Reverses the lean-revert: all beta packages stamped 1.0.0b260423 and alpha
packages stamped 1.0.0a260423 (Asia date, matching release cut time). All
26 non-core packages raise agent-framework-core lower bound from >=1.1.0,<2
to >=1.1.1,<2 to signal the validated cohort for this release. CHANGELOG
date updated to 2026-04-23.
* Add flaky test trend reporting to CI workflows
Parse JUnit XML (pytest.xml) from each integration test job and
aggregate results into a markdown trend report showing per-test
pass/fail/skip status across the last 5 runs.
Changes:
- Add python/scripts/flaky_report/ package (JUnit XML parser + trend
report generator following the sample_validation pattern)
- Add upload-artifact steps to all 6 integration test jobs in both
python-merge-tests.yml and python-integration-tests.yml
- Add python-flaky-test-report aggregation job with history caching
- Add --junitxml=pytest.xml to integration-tests.yml jobs (already
present in merge-tests.yml)

- Use datetime.now(timezone.utc) for accurate UTC timestamps
- Catch ET.ParseError per-file so corrupt XML doesn't crash the report
- Remove separate 'error' key from summary (errors folded into 'failed')
- Fix _short_name docstring to show actual dotted classname::name format

* Pass thread_id as session_id when constructing AgentSession in AG-UI
run_agent_stream() was constructing AgentSession without passing the
client's thread_id as session_id, causing every request to receive a
random UUID. This broke session continuity for HistoryProvider
implementations that rely on session_id matching the client's thread_id.
Pass session_id=thread_id in both the service-session and non-service
code paths so the session identity is consistent with the AG-UI client.

* Add test for service_session with no thread_id edge case (#5357)
When use_service_session=True but no thread_id/threadId is in the payload,
verify session_id is a generated UUID and service_session_id is None.

* Propagate session.service_session_id as A2A context_id
When A2AAgent is used behind the AG-UI protocol, the client thread_id is
stored in session.service_session_id but was never forwarded as the A2A
context_id. This broke session continuity across the AG-UI → A2A boundary.
Add an optional context_id keyword argument to _prepare_message_for_a2a()
and pass session.service_session_id from run(). The explicit
message.additional_properties["context_id"] still takes precedence.
Fixes#5345

run() passes session.service_session_id through to A2A message context_id
- Add test_run_message_context_id_takes_precedence_over_session: verifies
explicit message context_id wins over session fallback
- Update _prepare_message_for_a2a docstring to document context_id param
and its precedence rules

* Fix streaming response losing created_at from response.completed event (#5347)
The streaming path in _parse_chunk_from_openai did not extract created_at
from the response.completed event, unlike the non-streaming path in

* Catch agent errors and emit response.failed with real error message
Previously, unhandled exceptions from agent execution would bubble up
to the SDK orchestrator, which emits a generic 'An internal server

failures, model not found, etc.).
Now AgentFrameworkResponseHandler catches non-cancellation exceptions
and emits a proper response.failed event containing the real error
message, making it visible to clients and in logs.
OperationCanceledException still propagates for proper cancellation
handling by the SDK.

* Add Invocations protocol samples (hosted echo agent + client) (#5278)
Add Hosted-Invocations-EchoAgent: a minimal echo agent hosted via the
Invocations protocol (POST /invocations) using AddInvocationsServer and
MapInvocationsServer, bridged to an Agent Framework AIAgent through a
custom InvocationHandler.
Add SimpleInvocationsAgent: a console REPL client that wraps HttpClient
calls to the /invocations endpoint in a custom InvocationsAIAgent,
demonstrating programmatic consumption of the Invocations protocol.
Both samples default to port 8088 for consistency with other hosted
agent samples.
* Restructure FoundryHostedAgents samples into invocations/ and responses/
Align dotnet hosted agent samples with the Python side (PR #5281) by
reorganizing the directory structure:
- Remove HostedAgentsV1 entirely (old API pattern)
- Split HostedAgentsV2 into invocations/ and responses/ based on protocol
- Move Using-Samples accordingly (SimpleAgent to responses, SimpleInvocationsAgent to invocations)
- Update slnx with new project paths and add previously missing invocations projects
- Update README cd paths from HostedAgentsV2 to invocations or responses
- Rename .env.local to .env.example to match Python naming convention
- Fix format violations in newly included invocations projects
* Remove launchSettings, use .env for port configuration
- Delete all launchSettings.json files (port 8088 now comes from ASPNETCORE_URLS in .env)
- Add DotNetEnv to Hosted-Invocations-EchoAgent so it loads .env like the responses samples
- Create .env.example for EchoAgent with ASPNETCORE_URLS and ASPNETCORE_ENVIRONMENT
- Add AGENT_NAME to ChatClientAgent and FoundryAgent .env.example (required by those samples)
- Add AZURE_BEARER_TOKEN=DefaultAzureCredential to all .env.example files
- Update DevTemporaryTokenCredential in all 6 samples to treat the sentinel value
as unavailable, allowing ChainedTokenCredential to fall through to DefaultAzureCredential
- Update EchoAgent README with Configuration section
* Use placeholder for AGENT_NAME in Hosted-FoundryAgent .env.example
* Move FoundryResponsesHosting to responses/Hosted-WorkflowHandoff, use GetResponsesClient
* Rename Hosted-Workflows to Hosted-Workflow-Simple, Hosted-WorkflowHandoff to Hosted-Workflow-Handoff
* Remove FoundryResponsesRepl and empty FoundryResponsesHosting directory
* Add Dockerfiles, README, agent yamls and bearer token support to Hosted-Workflow-Handoff
- Add Dockerfile and Dockerfile.contributor for Docker-based testing
- Add agent.yaml and agent.manifest.yaml with triage-workflow as primary agent
- Add README.md following sibling pattern, noting Azure OpenAI vs Foundry endpoint
- Add DevTemporaryTokenCredential and ChainedTokenCredential for Docker auth
- Register triage-workflow as non-keyed default so azd invoke works without model
- Update .env.example with AZURE_BEARER_TOKEN sentinel

* Net: Prepare Foundry Preview Release (#5336)
* Prepare Foundry preview release 1.2.0-preview.*
Bump VersionPrefix to 1.2.0 and update the preview stamp date. Invert packaging opt-in so only the Foundry preview set produces NuGet packages:
- Microsoft.Agents.AI.Abstractions
- Microsoft.Agents.AI
- Microsoft.Agents.AI.Workflows
- Microsoft.Agents.AI.Workflows.Generators
- Microsoft.Agents.AI.Foundry
Flip IsReleased=false on the preview set so they pick up the -preview.YYMMDD.N suffix. Gate GeneratePackageOnBuild on IsPackable=true. Remove the global IsPackable=true from nuget-package.props so the repo-level default (false) applies to everything else.
* Lower preview VersionPrefix to 0.0.1
Retroactive preview publish: bump VersionPrefix and GitTag from 1.2.0 to 0.0.1 so the 5 Foundry preview packages emit as 0.0.1-preview.260417.1.
* Net: Publish all packages as 0.0.1-preview.260417.2 (#5341)
Revises the Foundry pre-release approach to publish ALL normally packable src projects as preview packages stamped 0.0.1-preview.260417.2, including projects previously flagged IsReleased=true or with a non-default VersionSuffix (rc/alpha).
nuget-package.props:
- Collapse the four conditional PackageVersion expressions (IsReleaseCandidate, VersionSuffix, default preview, IsReleased stable) into a single unconditional 0.0.1-preview.260417.2. On this preview-only branch every package ships with the same pre-release stamp regardless of per-project flags.
- Restore the global IsPackable=true default (offsetting the repo-wide IsPackable=false in Directory.Build.props). Projects that opt out (Mem0, Declarative) already set IsPackable=false AFTER importing this file so they remain non-packable.
- Remove the IsReleased-gated EnablePackageValidation line. Package validation does not apply to a 0.0.1 preview.
csproj reverts (Abstractions, Agents.AI, Workflows, Workflows.Generators, Foundry):
- Revert the IsPackable=true opt-in block introduced in #5336 (now redundant since the props default is true again).
- Restore IsReleased=true to its pre-PR value. The setting is now a no-op because the props no longer branches on it.
* Bump preview version to 260420.1 and fix AgentServer package deps (#5367)
- Bump PackageVersion to 0.0.1-preview.260420.1
- Bump Azure.AI.AgentServer.Core beta.21 -> beta.22 (required by
Azure.AI.AgentServer.Responses beta.3)
- Replace AgentHostTelemetry.ResponsesSourceName with local constant
(type made internal in AgentServer.Core beta.22)

* .NET: Hosted agents toolbox support (#5368)
* feat: Add Foundry Toolbox (MCP) support to AgentFrameworkResponseHandler
Adds support for Foundry Toolsets MCP proxy integration in the hosted agent
response handler. Toolsets connect at startup via IHostedService, gating the
readiness probe per spec §3.1. MCP tools are injected into every request's
ChatOptions and OAuth consent errors (-32006) are intercepted and surfaced as
mcp_approval_request + incomplete SSE events.
New files:
- FoundryToolboxOptions.cs: configuration POCO for toolset names and API version
- FoundryToolboxBearerTokenHandler.cs: DelegatingHandler with Azure Bearer token
auth, Foundry-Features header injection, and 3x exponential backoff on 429/5xx
- McpConsentContext.cs: AsyncLocal-based per-request consent state shared between
the tool wrapper and the response handler
- ConsentAwareMcpClientTool.cs: AIFunction wrapper that catches -32006 errors and
signals consent via shared state and linked CancellationTokenSource
- FoundryToolboxService.cs: IHostedService that creates McpClient per toolset at
startup and exposes cached tools
Modified files:
- AgentFrameworkResponseHandler.cs: injects toolbox tools into ChatOptions, sets
up linked CTS consent interception, emits mcp_approval_request on -32006
- ServiceCollectionExtensions.cs: adds AddFoundryToolboxes(params string[]) extension
- Microsoft.Agents.AI.Foundry.csproj: adds ModelContextProtocol and Azure.Identity
dependencies under NETCoreApp condition
Sample:
- Hosted-Toolbox: minimal hosted agent sample using AddFoundryToolboxes
* Rename toolset to toolbox in user-facing API; rename ConsentAwareMcpClientTool to ConsentAwareMcpClientAIFunction
* Add HostedMcpToolboxAITool for client-selectable Foundry toolboxes
Introduces HostedMcpToolboxAITool, a marker tool subclassing HostedMcpServerTool that rides the OpenAI Responses 'mcp' wire format to let clients request a specific Foundry toolbox per request.
- New FoundryAITool.CreateHostedMcpToolbox(name, version?) factory.
- FoundryToolboxOptions.StrictMode (default true) rejects unregistered toolboxes; set to false to allow lazy-open on first use.
- FoundryToolboxService.GetToolboxToolsAsync(name, version?) resolves cached or lazy-opened MCP tools.
- AgentFrameworkResponseHandler parses request.Tools for foundry-toolbox://name[?version=v] markers and injects resolved tools per request, merging with pre-registered ones.
- Unit tests for marker parsing and strict-mode resolution.
* Bump Azure.AI.Projects to 2.1.0-alpha; add ToolboxRecord/ToolboxVersion factory overloads + tests
* Fix PR review issues: retry off-by-one, URI encoding, docs, tests, build
- Fix off-by-one in FoundryToolboxBearerTokenHandler retry loop (4 attempts → 3)
- URI-encode version parameter in HostedMcpToolboxAITool.BuildAddress
- Add XML doc clarifying version pinning is reserved for future use
- Add comment clarifying AddHostedService deduplication safety
- Fix DevTemporaryTokenCredential expiry to use DateTimeOffset.MaxValue
- Fix AgentCard ambiguity in A2AServer sample with using alias
- Add 18 new unit tests for retry handler and ReadMcpToolboxMarkers

* Split Foundry into stable V1 and preview Hosting package
Extract hosted agent functionality from Microsoft.Agents.AI.Foundry into a
new Microsoft.Agents.AI.Foundry.Hosting preview package. This resolves NU5104
build errors caused by the stable Foundry package depending on prerelease
Azure SDK packages (Azure.AI.AgentServer.Responses, Azure.AI.Projects beta).
Changes:
- Create Microsoft.Agents.AI.Foundry.Hosting with VersionSuffix=preview,
targeting .NET Core only (net8.0/9.0/10.0)
- Move all Hosting/ source files to the new project
- Move ToolboxRecord/ToolboxVersion overloads to FoundryAIToolExtensions
- Revert Azure.AI.Projects to 2.0.0 in Directory.Packages.props;
Hosting uses VersionOverride for 2.1.0-beta.1
- Clean V1 Foundry csproj: remove beta deps, ASP.NET Core ref, hosting conditionals
- Update 8 hosted agent sample projects to reference Foundry.Hosting
- Split unit tests: ToolboxRecord/ToolboxVersion tests moved to Hosting/
- Add Foundry.Hosting to solution file

* Address PR review comments: experimental attrs, doc fixes, token propagation
- Add [Experimental(OPENAI001)] to all 7 public Hosting types per reviewer request
- Fix McpConsentContext XML doc: 'Thread-static' -> 'Async-local' (AsyncLocal
flows with ExecutionContext, not thread-static)
- Expand UserAgentMiddleware test regex to match prerelease versions (e.g. 1.0.0-rc.4)
- Propagate CancellationToken in AgentFrameworkResponseHandler session save

* Remove unnecessary MEAI001 suppression from stable Foundry package
MEAI001 was a leftover from when Hosting code lived in the same project.
The stable V1 Foundry package builds clean without it, and suppressing
experimental diagnostics in a released package can hide unintentional
exposure of experimental APIs to consumers.

* Fix OpenAIEmbeddingClient with /openai/v1 endpoint (#5068)
When base_url ends with /openai/v1/ and a credential is provided,
load_openai_service_settings was creating an AsyncAzureOpenAI client.
The Azure SDK rewrites deployment-based endpoints (including /embeddings)
by inserting /deployments/{model}/ into the URL, producing 404s on the
OpenAI-compatible /openai/v1 endpoint.
Use AsyncOpenAI instead of AsyncAzureOpenAI when the resolved base_url
targets /openai/v1, converting the Azure token provider to an async
api_key callable. The responses_mode path is unaffected because the
Responses API (/responses) is not in the SDK's rewrite list.

- Add _ensure_async_token_provider unit tests for both sync and async
token providers

* refactor: remove dead code
* refactor: remove ignore YieldsMessageAttribute
- the correct one to use is YieldsOutputAttribute
- fixes a comment that mistakenly refers to `.YieldsMessage()` which does not exist.
* fix: ChatForwardingExecutor does not use correct role for string messages
- make ChatForwardingExecutor use its configured role for string messages rather than always use ChatRole.User
- add ChatForwardingExecutor tests
* fixup: remove unused attribute
* test: Add tests for failure when .AsAgent used on a non-ChatProtocol workflow
* test: Add FunctionExecutor tests
- also fixes Send and YieldOutput type registration for synchronous output-returning delegates
* test: Suppress CodeCoverage for obsolete names
* fix: Re-add Obsolete attributes
- avoid hard-breaking change
- properly notify users that these attributes get ignored
Some providers, e.g. Gemini, do not use the CallId mechanism to disambiguate simultaneous function calls. This can result in message lists containing multiple turn to fail to filter properly.
The fix is to take advantage of the expectation that Handoff Orchestration is a "single-speaker" flow, which only has a single active AIAgent per "turn" and an agent's turn is not finished until all outstanding function calls are finished.
This allows us to expect that any ambiguous-CallId FunctionCallContent are either in separate turns or will have had a response before the next issued call with the same Id.
* Add set_stop_loss tool to concurrent_builder_tool_approval sample
Add a second approval-gated tool (set_stop_loss) to the concurrent workflow
tool approval sample to demonstrate handling approval requests for different
tools in the same concurrent workflow.
Changes:
- Add set_stop_loss(symbol, stop_price) with approval_mode='always_require'
- Include new tool in both agents' tool lists
- Update agent instructions and prompt to encourage stop-loss usage
- Update docstring to reflect two approval-gated tools
- Update sample output to show mixed approval requests
Fixes#4874

* Print tool name and arguments in concurrent sample's process_event_stream (#4874)

the tool name and arguments when collecting approval requests, matching the
sample output comment and the sequential_builder_tool_approval.py pattern.

* Add None-guard for function_call access in tool approval sample (#4874)
Add explicit None-checks before accessing function_call.name and
function_call.arguments in concurrent_builder_tool_approval.py. The
function_call field is typed Content | None, so direct attribute access
without a guard could raise AttributeError and required type: ignore
comments. The None-guard is consistent with the pattern used in
_agent_run.py and removes the suppression comments.
Also add a regression test verifying that function_call defaults to None
and that the None-guard pattern is safe.

* Apply same function_call None-guard to sibling tool-approval samples (#4874)
Apply the same fix to sequential_builder_tool_approval.py and
group_chat_builder_tool_approval.py, which had the identical pattern
of accessing function_call.name/arguments without a None-guard.

* Add azure-monitor-opentelemetry to dev deps
Fixes Samples & Markdown CI failure. The PR's new transitive dep on
azure-monitor-opentelemetry-exporter (via azure-ai-agentserver-core) makes
pyright resolve the azure.monitor.opentelemetry namespace, flipping the
check_md_code_blocks diagnostic for `configure_azure_monitor` from
reportMissingImports (filtered) to reportAttributeAccessIssue (not filtered).
Installing the umbrella azure-monitor-opentelemetry package in dev makes
pyright resolve the symbol correctly, matching the install guidance the
observability README already gives users.

* Expose forwarded_props to agents and tools via session metadata (#5239)
Include forwarded_props from AG-UI request input_data in session.metadata
(agent runner) and function_invocation_kwargs (workflow runner) so that
agents, tools, and workflow executors can access request-level metadata
such as invocation source flags from CopilotKit.
- Add forwarded_props to base_metadata in _agent_run.py when present
- Add 'forwarded_props' to AG_UI_INTERNAL_METADATA_KEYS to filter it
from LLM-bound client metadata
- Extract forwarded_props in _workflow_run.py and pass via
function_invocation_kwargs to workflow.run()
- Accept both snake_case and camelCase keys (forwarded_props/forwardedProps)

can correctly infer the ResponseStream return type.
Also remove unused pytest import in test file.

- Change _build_safe_metadata to drop (with warning) keys whose
serialized values exceed 512 chars instead of truncating into invalid
JSON
- Rewrite metadata tests to exercise _build_safe_metadata directly with
JSON-decodability and truncation assertions
- Add workflow tests for empty dict forwarded_props, stream=True
assertion, and signature-gated kwarg dropping

* Add support for the Foundry Toolbox in MAF
Introduces a Foundry Toolbox integration: FoundryChatClient gains a
get_toolbox() helper plus select_toolbox_tools(), normalize_tools in
the core package flattens tool-collection wrappers (ToolboxVersionObject
and generic iterables, while leaving Pydantic BaseModel instances
alone), and the new agent_framework.foundry namespace re-exports the
toolbox helpers. Ships with unit tests, a sample, and a design doc.
azure-ai-projects is pinned to the public >=2.0.0,<3.0 range and the
lockfile resolves from public PyPI. The toolbox test module skips when
Toolbox* types are unavailable so CI stays green until the public 2.1.0
SDK lands. OMC tooling directories (.omc/, .omx/) are gitignored.

* fix: Add session support for Handoff-hosted Agents
In order to better support using `Workflows` hosted as `AIAgents` inside of Handoff workflows, we need to make proper use of AgentSession. This causes potential issues around checkpointing and making sure that we properly compute only the new incoming messages for each agent invocation.
* fix: AgentSession checkpointing using AIAgent's Serialize/Deserialize methods
We cannot rely on implicit serialization through `HandoffHostState` because we are missing type information.
* fix: Thread safety issue in `MultiPartyConversation.AllMessages`
* fix: Enable unwrapping of FunctionResultContent when ExternalRequest was wrapped into FunctionCallContent
* fix: Foundry Agents without description in Handoff
Foundry Agents without a description set will return an empty string (rather than null) for the description. This was breaking the fallback logic for `handoffReason`.
* test: Add unit tests
* Foundry Evals integration for .NET
- Core evaluation framework: EvalItem, LocalEvaluator, FunctionEvaluator, EvalChecks
- IAgentEvaluator interface with MeaiEvaluatorAdapter bridge
- AgentEvaluationExtensions for agent.EvaluateAsync() overloads
- FoundryEvals wrapping MEAI quality/safety evaluators
- ConversationSplitters (LastTurn, Full) and IConversationSplitter
- EvalItem.PerTurnItems() for multi-turn decomposition
- HasImageContent for multimodal content detection
- WorkflowEvaluationExtensions for per-agent workflow evaluation
- 7 eval samples mirroring Python parity:
02-agents/Evaluation: SimpleEval, ExpectedOutputs, Multimodal
03-workflows/Evaluation: WorkflowEval
05-end-to-end/Evaluation: FoundryQuality, MixedProviders, ConversationSplits
- Comprehensive unit tests (1958 passing)

* Rewrite FoundryEvals to use real Foundry Evals API
Replace MEAI evaluator shim with actual OpenAI EvaluationClient protocol
methods. FoundryEvals now creates eval definitions, submits runs, polls
for completion, and fetches per-item results server-side.
- New constructor: FoundryEvals(AIProjectClient, model, evaluators)
- Add FoundryEvalConverter for MEAI ChatMessage -> Foundry JSON format
- Add EvalId, RunId, ReportUrl to AgentEvaluationResults
- All 20 built-in evaluator constants now work (agent, tool, quality, safety)
- Remove Microsoft.Extensions.AI.Evaluation.Quality/Safety dependencies
- Update all samples for new constructor (no more ChatConfiguration)

* Fix review: conversation fidelity, eval caching, fallback tests
- WorkflowEvaluationExtensions: preserve full response messages (tool calls,
intermediate) instead of synthetic 2-message conversation. Cast completed
Data to AgentResponse and use Messages when available, fallback to text.
- FoundryEvals: cache evalId per schema shape (hasContext, hasTools) so
subsequent EvaluateAsync calls create runs under the same eval definition.
- MeaiEvaluatorAdapter: code already correctly passes queryMessages (not full
conversation) to IEvaluator — no change needed, verified by inspection.
- Add tests: AgentResponse full messages preservation, unknown object
ToString() fallback for ExtractAgentData.

* PR review round 4: wire up tool extraction, remove eval cache, fix null safety
- BuildEvalItem: extract tools from agent via GetService<ChatOptions>() into EvalItem.Tools (Python parity)
- FoundryEvals: remove eval ID cache - each call creates fresh definition (matches Python behavior)
- FoundryEvals: replace null-forgiving operators with descriptive InvalidOperationException
- MixedProviders sample: remove unnecessary explicit PackageReferences (transitively provided)
- FoundryEvalConverter: document that tool results take precedence over text content
- Add LocalEvaluator zero-checks test documenting 0 metrics = failed behavior

* Python-dotnet parity: 9 feature gaps filled
New checks:
- ToolCallArgsMatch() — verify tool call names + argument subset match
- ToolCalledCheck(ToolCalledMode.Any, ...) — match any of the specified tools
- ToolCalledMode enum (All/Any)
FoundryEvals enhancements:
- Default evaluators now [Relevance, Coherence, TaskAdherence] (was Relevance, Coherence)
- Auto-add ToolCallAccuracy when items have tool definitions
- EvaluateTracesAsync — evaluate by response_ids, trace_ids, or agent_id
- EvaluateFoundryTargetAsync — evaluate deployed Foundry targets
Result type enrichment:
- AgentEvaluationResults: added Status, Error, PerEvaluator, DetailedItems
- New EvalItemResult/EvalScoreResult/PerEvaluatorResult types
- FoundryEvals populates all new fields from API responses
Workflow fix:
- Skip internal executors (_*, input-conversation, end-conversation, end)
Tests: 8 new tests covering ToolCallArgsMatch, ToolCalledMode.Any, internal executor filtering

* Blocking link check for outdated package in DevUI.
* Replace Dictionary<string, object> payloads with typed wire models
Introduce internal FoundryEvalWireModels.cs with compile-time-safe types
for the OpenAI Evals API wire format. The OpenAI .NET SDK (2.9.1) only
provides protocol-level methods with BinaryContent/ClientResult — no
typed request models. These internal models replace scattered dictionary
literals with [JsonPropertyName]-annotated classes, giving:
- Compile-time safety (typos become build errors)
- Single point of change when the API evolves
- IntelliSense discoverability
- Cleaner serialization via JsonPolymorphic for content items
Models: WireContentItem hierarchy (text, image, tool_call, tool_result),
WireMessage, WireEvalItemPayload, WireTestingCriterion, WireItemSchema,
WireCreateEvalRequest, WireCreateRunRequest, and data source variants.

* Skip metric when Foundry returns neither score nor passed
When an evaluator returns no score and no passed value, the previous
code created BooleanMetric(name, false), which falsely failed items
via ItemPassed. Now we skip the MEAI metric entirely for indeterminate
results — the raw data remains available in DetailedItems for diagnostics.

* refactor: move finish_reason tests into test_types.py per review feedback
Move all finish_reason test cases from the separate test_finish_reason.py
file into test_types.py as requested by eavanvalkenburg. Tests are placed
in a new '# region finish_reason' section at the end of the file.
* fix: use model instead of model_id in _process_update
Address PR review feedback from @eavanvalkenburg — ChatResponse and
ChatResponseUpdate both use 'model', not 'model_id'.
* fix: resolve SIM102 lint error in _process_update
Combine nested if statements for AgentResponse finish_reason check
to satisfy ruff SIM102 rule, with line wrapping to stay under 120 chars.
* fix: resolve pyright reportArgumentType in map_chat_to_agent_update
Add type: ignore[arg-type] for FinishReason NewType widening when
passing ChatResponseUpdate.finish_reason to AgentResponseUpdate.
Matches existing patterns in the codebase (40+ similar ignores).
* Fix url_citation annotations dropped in streaming (#5029)
Add url_citation branch to the streaming annotation handler in
_parse_chunk_from_openai, mirroring the existing non-streaming path.
The handler creates an Annotation with type='citation', title, url,
and annotated_regions (TextSpanRegion), wrapped in Content.from_text.

- Update Anthropic from 12.11.0 to 12.13.0
- Update Anthropic.Foundry from 0.4.2 to 0.5.0
- Change Anthropic project from release candidate to preview
- Add new IBetaService members (Agents, Environments, Sessions, Vaults) to test mock
Fixes#5246
When a custom @executor transforms agent output and sends a plain str,
the downstream AgentExecutor.from_str handler loses the full conversation
context. This adds a with_text() helper that creates a new
AgentExecutorResponse with replaced text while preserving the prior
conversation chain, so AgentExecutor.from_response is invoked instead.
- Add with_text(text) method to AgentExecutorResponse dataclass
- Add 3 regression tests in test_full_conversation.py

* Improve workflow unit tests
* Update test name prefix for clarity.
* Update tests to surface any errors.
* fix check-point restore-time race in off-thread workflow event stream
* Fixes an intermittent checkpoint-restore race in in-process workflow runs.
The local MCP server can't be used for hosted tools tests because
Anthropic's backend needs to reach the MCP URL from their infrastructure
(not localhost on the CI runner). Revert to learn.microsoft.com/api/mcp
but catch BadRequestError, InternalServerError, APIConnectionError, and
APITimeoutError and pytest.skip so upstream outages don't block the
merge queue.
* Python: use local MCP server for hosted tools test and broaden image assertion
The hosted tools integration test was hitting rate limits on the external
learn.microsoft.com MCP server, causing persistent failures that retries
couldn't recover from. Switch to the local MCP server already spun up in
CI via LOCAL_MCP_URL, skipping when the env var isn't set.
Also broaden the image description assertion to accept common synonyms
(cottage, mansion, villa, etc.) instead of just "house", since the model
legitimately uses varied vocabulary for the same image.
* Address review feedback: validate LOCAL_MCP_URL scheme and use word boundaries
- Skip hosted tools test when LOCAL_MCP_URL lacks http/https scheme,
matching the pattern used in test_mcp.py.
- Use regex word boundaries for image assertion to avoid false matches
like "villain" matching "villa".
The misc-integration job (Anthropic, Ollama, MCP) frequently fails on merge to main when the upstream MCP server (e.g. learn.microsoft.com/api/mcp) returns a transient rate-limit error. The previous 5s retry delay is too short to ride out the upstream backoff window, so all retries fail and the merge queue is blocked. Bumping to 30s gives the upstream a chance to recover before pytest-retry re-runs the test.

* Python: Skip get_final_response in OTel _finalize_stream when stream errored
When a streaming error occurs, _finalize_stream (a cleanup hook registered by
AgentTelemetryLayer) was unconditionally calling get_final_response(), which
triggers all registered result hooks including after_run context providers.
This caused providers to fire incorrectly on error paths.
Guard against this by checking result_stream._consumed: True only after
StopAsyncIteration (normal completion), False when an exception was raised.
The fix applies to both the chat client and agent telemetry layers.
Closes#5231
* Python: Expose consumed/stream_error on ResponseStream and capture error in OTel span
Address Copilot review feedback on #5232:
- Add `_stream_error: Exception | None` to ResponseStream, set in __anext__'s
except branch so cleanup hooks can inspect the failure.
- Expose public `consumed` and `stream_error` properties to avoid coupling
observability.py to private stream internals.
- Update both _finalize_stream closures (chat and agent layers) to use the
public properties and call capture_exception() with the stream error before
returning early, ensuring the OTel span records the failure rather than
closing silently.
* Python: Address Copilot review feedback on stream error handling
- Use stream_error is not None as the guard in _finalize_stream instead of
not consumed, so the early-return path is keyed precisely to actual errors
rather than any non-normal completion state.
- Clear _stream_error after _run_cleanup_hooks() completes to avoid retaining
the exception traceback (and any large object graphs it references) on the
stream instance beyond the cleanup phase.
* Python: Remove consumed/stream_error properties, use private attrs directly
Per review feedback: since observability.py and _types.py are in the same
package, accessing _stream_error directly is fine and the public properties
are unnecessary.
* Python: Fix Pyright reportPrivateUsage via inline ignore comments
Keep _stream_error private (consistent with rest of ResponseStream), and
suppress reportPrivateUsage at the call sites in observability.py with
inline pyright: ignore comments — access is intentional within the package.
* AG-UI deterministic state updates from tool results
* fix(ag-ui): address PR #5201 review comments
1. Add missing AGUIEventConverter, AGUIHttpService, __version__ to
_IMPORTS in core ag_ui lazy-export list to match the .pyi stub.
2. Coalesce predictive and deterministic state snapshots into a single
StateSnapshotEvent when both mechanisms are active on the same tool
result, reducing redundant snapshot traffic.
3. Update state_update() docstring to clarify that a predictive snapshot
may be emitted before the deterministic one when predict_state_config
is active.

_clone_chat_agent() was using agent.agent_middleware (agent-level only)

* Python: Add allowed_checkpoint_types support to CosmosCheckpointStorage (#5200)
Add allowed_checkpoint_types parameter to CosmosCheckpointStorage for
parity with FileCheckpointStorage. This ensures both providers use the
same restricted pickle deserialization by default.
Changes:
- Accept allowed_checkpoint_types kwarg in __init__, stored as frozenset
- Convert _document_to_checkpoint from @staticmethod to instance method
- Forward allowed_types to decode_checkpoint_value on all load paths
- Update class docstring to describe the new parameter
- Add tests covering built-in safe types, app type opt-in/blocking,
and all load paths (load, list_checkpoints, get_latest)
- Add changelog entry noting the breaking behavior change
BREAKING CHANGE: CosmosCheckpointStorage now uses restricted pickle
deserialization by default. Checkpoints containing application-defined
types will require passing those types via allowed_checkpoint_types.

* Harden Python checkpoint persistence defaults
Add RestrictedUnpickler to _checkpoint_encoding.py that limits which
types may be instantiated during pickle deserialization. By default
FileCheckpointStorage now uses the restricted unpickler, allowing only:
- Built-in Python value types (primitives, datetime, uuid, decimal,
collections, etc.)
- All agent_framework.* internal types
- Additional types specified via the new allowed_checkpoint_types
parameter on FileCheckpointStorage
This narrows the default type surface area for persisted checkpoints
while keeping framework-owned scenarios working without extra
configuration. Developers can extend the allowed set by passing
"module:qualname" strings to allowed_checkpoint_types.
The decode_checkpoint_value function retains backward-compatible
unrestricted behavior when called without the new allowed_types kwarg.

* Fix reasoning text done events duplicating streamed delta content (#5157)
The OpenAI Responses API sends both reasoning_text.delta (incremental
chunks) and reasoning_text.done (full accumulated text) events. The
chat client was emitting Content for both, causing ag-ui to append the
full done text onto already-accumulated delta text, producing
duplicated reasoning output.
Stop emitting Content for reasoning_text.done and
reasoning_summary_text.done events, matching how output_text.done is
already handled (not emitted). The deltas contain all the content;
the done event is redundant.

* Address review feedback for #5157: Python: [Bug]: "type": "response.reasoning_text.delta" and "response.reasoning_text.done" both get exposed as "text_reasoning"
* Fix AG-UI reasoning streaming to use proper Start/End pattern (#5157)
_emit_text_reasoning now follows the same streaming pattern as _emit_text:
- Emits ReasoningStartEvent/ReasoningMessageStartEvent only on the first
delta for a given message_id
- Emits only ReasoningMessageContentEvent for subsequent deltas
- Defers ReasoningMessageEndEvent/ReasoningEndEvent until
_close_reasoning_block is called (on content type switch or end-of-run)
This produces the correct protocol pattern:
ReasoningStartEvent
ReasoningMessageStartEvent
ReasoningMessageContentEvent(delta1)
ReasoningMessageContentEvent(delta2)
ReasoningMessageEndEvent
ReasoningEndEvent
Instead of wrapping every delta in a full Start→End sequence.
Backward compatibility is preserved: calling _emit_text_reasoning without
a flow argument still produces the full sequence per call.

* Guard against empty text in _parse_structured_response_value (#5145)
When using response_format with background=True (Responses API), polling
an in-progress response produces empty text. _parse_structured_response_value
unconditionally passed this to model_validate_json/json.loads, causing
ValidationError or JSONDecodeError.
Add an early return of None when text is empty, matching the existing
guard for response_format=None. This allows .value to safely return None
for in-progress background responses.

* Python: Fix image content serialization sending null file_id to Foundry API
Omit file_id from input_image dict when not present instead of including
it as null, which Azure AI Foundry's stricter schema validation rejects.
* Python: Fix Foundry API rejecting rich content in function_call_output
Azure AI Foundry does not support list-format output in function_call_output
items. Add SUPPORTS_RICH_FUNCTION_OUTPUT flag (default True) to
RawOpenAIChatClient, set to False in RawFoundryChatClient so Foundry
falls back to string output for tool results with images/files.
Also omit file_id from input_image dicts when not set, since Foundry
rejects explicit nulls.
* Python: Surface rich tool content as user message when Foundry lacks support
When SUPPORTS_RICH_FUNCTION_OUTPUT is False, image/file items from tool
results are injected as a follow-up user message so the model can still
process the visual content via Foundry's supported user message format.

* Fix GitHubCopilotAgent not calling context provider hooks (#3984)
GitHubCopilotAgent accepted context_providers in its constructor but
never called before_run()/after_run() on them in _run_impl() or
_stream_updates(), silently ignoring all context providers.
Add _run_before_providers() helper to create SessionContext and invoke
before_run on each provider. Both _run_impl() and _stream_updates() now
run the full provider lifecycle: before_run before sending the prompt
(with provider instructions prepended) and after_run after receiving the
response. This follows the same pattern used by A2AAgent.

Fixes#3984
* fix(#3984): address review feedback for context provider integration
- Build prompt from session_context.get_messages(include_input=True) so
provider-injected context_messages are included in both non-streaming
and streaming paths (review comments #1, #2)
- Preserve timeout in opts (use get instead of pop) so providers can
observe it via context.options (review comment #3)
- Eliminate streaming double-buffer: move after_run invocation to a
ResponseStream result_hook (matching Agent class pattern) instead of
maintaining a separate updates list in the generator (review comment #4)
- Improve _run_before_providers docstring
Add tests for:
- Context messages included in prompt (non-streaming + streaming)
- Error path: after_run NOT called when send_and_wait/streaming raises
- Multiple providers: forward before_run, reverse after_run ordering
- BaseHistoryProvider with load_messages=False is skipped
- Streaming after_run response contains aggregated updates
- Streaming with no updates still sets empty response
- Timeout preserved in session context options for providers
Note: _run_before_providers remains on GitHubCopilotAgent for now. A
follow-up PR should extract it to BaseAgent so subclasses can reuse it
without duplicating the provider iteration logic.

Fixes#4353
The `Mem0ContextProvider` and `RedisContextProvider` no longer support
`thread_id` or `scope_to_per_operation_thread_id` parameters. This commit
updates the affected samples and READMEs to use only the currently
supported API (`user_id`, `agent_id`, `application_id`).
Changes:
- mem0_sessions.py: Remove `thread_id` and
`scope_to_per_operation_thread_id` from examples 1 and 2, rewrite to
demonstrate user-scoped and agent-scoped memory patterns
- redis_sessions.py: Update module docstring to remove references to
removed thread scoping params
- mem0/README.md: Update Memory Scoping docs to reflect current API
- redis/README.md: Remove `thread_id` and
`scope_to_per_operation_thread_id` references from docs
* Address Copilot review: rename thread_scope functions, fix docstring
- Rename `example_global_thread_scope` -> `example_global_memory_scope`
- Rename `example_per_operation_thread_scope` -> `example_agent_scoped_memory`
- Update example 2 docstring to mention `application_id` alongside
`user_id` and `agent_id` since it's set in the provider config
- Update module docstring scenario 2 to include `application_id`
* fix: rebase onto main, address giles17 review feedback
- Resolve merge conflicts by rebasing all 4 original files onto current main
- Address giles17's agent review suggestions:
- mem0_basic.py: update comment to remove thread_id from scoping list
- mem0_oss.py: update comment to remove thread_id from scoping list
- redis_sessions.py: rename Example 2 from "Agent-Scoped Memory" to
"Hybrid Vector Search" to accurately describe what it demonstrates
- redis/README.md: update Example 2 description to match renamed example

* Add Python A2A agent-as-function-tools sample
Port of the .NET A2AAgent_AsFunctionTools sample to Python.
Resolves a remote A2A agent card, converts each skill to a
FunctionTool via as_tool(), and registers them with a host agent
using AzureOpenAIResponsesClient.
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* Sanitize A2A skill names before passing to as_tool()
as_tool() only auto-sanitizes when name is omitted. Since we pass
skill.name explicitly, we need to strip special characters ourselves.

* Python: Add header_provider to MCPStreamableHTTPTool (#4808)
Add a header_provider callback parameter to MCPStreamableHTTPTool that
enables injecting dynamic per-request HTTP headers from runtime kwargs
(originating from FunctionInvocationContext.kwargs set in agent middleware).
The implementation uses contextvars and httpx event hooks to ensure headers
are task-local and safe for concurrent tool calls:
- header_provider receives the runtime kwargs dict and returns headers
- call_tool sets a ContextVar before delegating to MCPTool.call_tool
- An httpx request event hook reads from the ContextVar and injects headers
Example usage:
mcp_tool = MCPStreamableHTTPTool(
name="web-api",
url="https://api.example.com/mcp",
header_provider=lambda kwargs: {
"X-Auth-Token": kwargs.get("auth_token", ""),
},
)

* Address review feedback for #4808: Python: [Bug]: Unable to pass AgentContext to MCPStreamableHTTPTool
* Add test for header_provider via FunctionTool.invoke with FunctionInvocationContext
Addresses PR review comment: exercises the full pipeline from
FunctionInvocationContext.kwargs through FunctionTool.invoke to
MCPStreamableHTTPTool.call_tool and header_provider, rather than
testing call_tool in isolation.

* fix: resolve mypy redundant-cast errors while keeping pyright happy
Use cast(list[Any], x) with type: ignore[redundant-cast] comments to
satisfy both mypy (which considers casting Any redundant) and pyright
strict mode (which needs explicit casts to narrow Unknown types).
Also fix evaluator decorator check_name type annotation to be
explicitly str, resolving mypy str|Any|None mismatch.

* Address PR review round 2: bugs, tests, and architecture
Code fixes:
- Fix _normalize_queries inverted condition (single query now replicates
to match expected_count)
- Fix substring match bug: 'end' in 'backend' matched; use exact set
lookup for executor ID filtering
- Fix used_available_tools sample: tool_definitions→tools param, use
FunctionTool attribute access instead of dict .get()
- Add None-check in _resolve_openai_client for misconfigured project
- Add Returns section to evaluate_workflow docstring
- Cache inspect.signature in @evaluator wrapper (avoid per-item reflection)
Architecture:
- Extract _evaluate_via_responses as module-level helper; evaluate_traces
now calls it directly instead of creating a FoundryEvals instance
- Move Foundry-specific typed-content conversion out of core to_eval_data;
core now returns plain role/content dicts, FoundryEvals applies
AgentEvalConverter in _evaluate_via_dataset
Tests:
- evaluate_response() deprecation warning emission and delegation
- num_repetitions > 1 with expected_output and expected_tool_calls
- Mock output_items.list in test_evaluate_calls_evals_api
- Update to_eval_data assertions for plain-dict format
- Unknown param error now raised at @evaluator decoration time

- Better error message when queries provided without agent
- Import-time asserts for evaluator set consistency
- Remove 28 redundant @pytest.mark.asyncio decorators
- Add doc note about _raw_arguments sensitive data
- Tests: tool_called_check mode=any, _normalize_queries branches,

tool-call data to external evaluation services
- Add NOTE comment on to_eval_data message serialization dropping
non-text content (tool calls, results)
- Eliminate double conversation split in _evaluate_via_dataset: build
JSONL dicts directly from split_messages + AgentEvalConverter
- Raise poll_interval floor from 0.1s to 1.0s to prevent rate-limit
exhaustion
- Fix MagicMock(name=...) bug in test: sets display name not .name attr

* Address PR review round 5: reliability, docs, test coverage
Code fixes:
- Move import-time RuntimeError checks to unit tests (avoids breaking
imports for all users on developer set-drift mistake)
- _filter_tool_evaluators now raises ValueError when all evaluators
require tools but no items have tools (was silently substituting)
- Add poll_interval upper bound (60s) to prevent single-iteration sleep
- Log exc_info=True in _fetch_output_items for debugging API changes
- Fix evaluate() docstring: remove claim about Responses API optimization
- Validate target dict has 'type' key in evaluate_foundry_target
- Document to_eval_data() limitation: non-text content is omitted
Tests:
- TestEvaluatorSetConsistency: verify _AGENT/_TOOL subsets of _BUILTIN
- TestEvaluateTracesAgentId: agent_id-only path with lookback_hours
- TestFilterToolEvaluatorsRaises: ValueError on all-tool no-items
- TestEvaluateFoundryTargetValidation: target without 'type' key
- Assert items==[] on failed/canceled poll results
- Mock output_items.list in response_ids test for full flow
- TestAllPassedSubResults: result_counts=None + sub_results delegation
and parent failures override sub_results
- TestBuildOverallItemEmpty: empty workflow outputs returns None
Skipped r5-07 (_raw_arguments length hint): marginal debugging value,
could leak content size information.

* Simplify self-reflection sample using FoundryEvals
Replace ~80 lines of manual OpenAI evals API code (create_eval,

- Remove create_openai_client(), create_eval(), run_eval() functions
- Remove openai SDK type imports (DataSourceConfigCustom, etc.)

* Replace ConversationSplitter type alias with Protocol
ConversationSplitter is now a runtime-checkable Protocol with a named
'conversation' parameter, making the expected signature self-documenting.
ConversationSplit enum members gain a __call__ method so they satisfy
the protocol directly -- ConversationSplit.LAST_TURN(conversation) works.
This simplifies _split_conversation from an isinstance dispatch to a
single split(conversation) call.

* Add API breaking change validation for RC packages
Enable .NET Package Validation for release candidate packages to detect
API breaking changes in CI. This follows the same pattern used by
Semantic Kernel, centralized through nuget-package.props.
Changes:
- Enable EnablePackageValidation for IsReleaseCandidate packages
- Update PackageValidationBaselineVersion to 1.0.0-rc4 (latest published)
- Generate CompatibilitySuppressions.xml for existing known API changes
in 5 packages (AI, AzureAI, OpenAI, Workflows, Workflows.Declarative.AzureAI)
- Opt out Workflows.Declarative.Mcp (not yet published to NuGet)
- Add breaking changes guidance to CONTRIBUTING.md
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* Address PR review feedback
- Remove unnecessary empty PackageValidationBaselineVersion override
in Workflows.Declarative.Mcp.csproj (EnablePackageValidation=false
is sufficient)
- Tighten CONTRIBUTING.md wording to clarify opt-out possibility

* Enable package validation for GA packages (no VersionSuffix)
Expand the EnablePackageValidation condition to also cover future GA
packages that have no VersionSuffix, not just RC packages.
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* Fix EnablePackageValidation GA condition to check PackageVersion
The previous condition VersionSuffix=='' matched all packages (preview
included) since VersionSuffix defaults to empty. Now uses two separate
conditions: one for RC, one for true GA (PackageVersion == VersionPrefix).

* Add IsGeneralAvailable flag for package validation
Replace fragile PackageVersion condition with explicit IsGeneralAvailable
property, following the same per-project self-declaration pattern as
IsReleaseCandidate.
- Directory.Build.props: Add IsGeneralAvailable=false default
- nuget-package.props: EnablePackageValidation on RC OR GA
- CONTRIBUTING.md: Update docs to mention both flags
When packages go GA, they set IsGeneralAvailable=true in their .csproj.

* Changes
* Fix ChatClientAgent streaming responses missing MessageId
Generate fallback MessageId in ChatClientAgent.RunCoreStreamingAsync when
the underlying LLM provider does not set ChatResponseUpdate.MessageId.
Without a MessageId the AGUI converter's null==null check silently drops
all text content, causing CopilotKit Zod validation errors.
Changes:
- ChatClientAgent: generate msg_{Guid} fallback via ??= in streaming loop
- AgentResponseExtensions: sync wrapper MessageId back to RawRepresentation
in AsChatResponseUpdate() so downstream consumers see the value
- Add unit tests for both fixes and AGUI streaming MessageId scenarios
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* Address PR #4615 review comments
- Fix MessageId seeding: use first-seen provider MessageId (or generate
fallback) and apply consistently to all chunks in the stream, preventing
message splitting when providers set MessageId only on the first chunk
- Add test for mixed MessageId scenario (first chunk only)
- Fix skipped TextStreaming test: assert Empty (not NotEmpty) to match
actual null==null behavior
- Fix skipped ToolCalls test: assert empty ParentMessageId to match
actual empty-string passthrough behavior
* Handle empty MessageId in AsChatResponseUpdate sync
Treat empty/whitespace MessageId the same as null when syncing from
the AgentResponseUpdate wrapper back to RawRepresentation. Providers
that return empty string MessageId (e.g. tool call responses) now get
the wrapper value recovered correctly.
Add test for empty string MessageId recovery scenario.
* Move MessageId fallback generation to AGUI layer
Move fallback MessageId generation from ChatClientAgent to
AsAGUIEventStreamAsync, addressing the architectural concern that
MessageId is nullable in the AIAgent abstraction and the requirement
for non-null values is specific to the AGUI protocol.
The AGUI layer now generates a fallback MessageId for null or
empty/whitespace values, covering all agent types (not just
ChatClientAgent) including external implementations.
Changes:
- Revert MessageId generation from ChatClientAgent.RunCoreStreamingAsync
- Add fallback MessageId generation in AsAGUIEventStreamAsync for
null/empty MessageId values (handles both null and whitespace)
- Unskip and update AGUI tests to verify fallback generation
- Update ChatClientAgent tests to reflect passthrough behavior
* Revert AsChatResponseUpdate MessageId sync-back
Remove the MessageId sync-back logic from AsChatResponseUpdate() as it
is no longer needed. With fallback generation moved to the AGUI layer,
the abstraction layer should not mutate the RawRepresentation object.
Revert to the original passthrough behavior for AsChatResponseUpdate()
and update tests accordingly.

* Include reasoning messages in MESSAGES_SNAPSHOT (#4843)
FlowState now tracks reasoning messages emitted during a run.
_emit_text_reasoning() persists reasoning (including encrypted_value)
into flow.reasoning_messages, and _build_messages_snapshot() appends
them to the final MESSAGES_SNAPSHOT event.
Changes:
- Add reasoning_messages field to FlowState
- Update _emit_text_reasoning() to accept optional flow parameter
- Include reasoning_messages in _build_messages_snapshot()
- Add 'reasoning' to ALLOWED_AGUI_ROLES so normalize_agui_role()
preserves the role through snapshot round-trips
- Skip reasoning messages in agui_messages_to_agent_framework() since
they are UI-only state and should not be forwarded to LLM providers
- Add regression tests for snapshot emission, encrypted value
preservation, and multi-turn round-trip with reasoning

* Fix streaming path to deliver mcp_server_tool_result content (#4814)
Remove premature mcp_server_tool_result emission from the
response.output_item.added/mcp_call handler — at that point the MCP
server has not yet responded and output is always None.
Add a handler for response.mcp_call.completed that emits
mcp_server_tool_result with the actual tool output, matching the
non-streaming path behavior.

* Fix streaming path to deliver mcp_server_tool_result content (#4814)
Stop eagerly emitting mcp_server_tool_result on response.output_item.added
(when output is always None). Instead, handle response.output_item.done for
mcp_call items, which carries the full McpCall with populated output.
This matches the non-streaming path which guards with 'if item.output is not
None' before emitting the result.

The `sessionId`, an optional parameter when starting a new session when

* Fix PydanticSchemaGenerationError with PEP 563 annotations in @tool
_resolve_input_model used raw param.annotation from inspect.signature(),

* [BREAKING] Refactor middleware layering and raw clients
Reorder chat client layers so function invocation wraps chat middleware, and chat middleware stays outside telemetry while still running for each inner model call. Add middleware pipeline caching, refresh docs and samples, and split Anthropic into raw and public clients to match the standard layering model.

* Tighten typing ignores in ancillary modules
Add targeted typing ignores in workflow visualization and lab modules so pyright stays clean alongside the middleware refactor work.

* Fix categorize_middleware to unpack tuple/Sequence and use relative MRO assertions
- Broaden isinstance check in categorize_middleware from list to Sequence
so tuples and other Sequence types are properly unpacked instead of
being appended as a single item.
- Replace fragile hardcoded MRO index assertions in anthropic test with
relative ordering via mro.index().
- Add regression tests for categorize_middleware with tuple, list, and
None inputs.

* Fix middleware string decomposition, add middleware param to FunctionInvocationLayer, and add tests (#4710)
- Guard categorize_middleware Sequence check against str/bytes to prevent
character-by-character decomposition of accidentally passed strings
- Add explicit middleware parameter to FunctionInvocationLayer.get_response
and merge it into client_kwargs before categorization, fixing the
inconsistency where only OpenAIChatClient supported this parameter
- Add assertions that RawAnthropicClient does not inherit convenience layers
- Add chat middleware cache test with non-empty base middleware
- Add tests for single unwrapped middleware item and string input

* Emit TOOL_CALL_RESULT events on approval resume (#4589)
When a tool call is approved via the interrupt/resume flow,
_resolve_approval_responses executes the tool and injects the result
into the messages array, but no TOOL_CALL_RESULT SSE event was yielded
to the client.
Changes:
- _resolve_approval_responses now returns the list of resolved
function_result Content objects instead of None
- run_agent_stream yields ToolCallResultEvent for each resolved
approval result after RunStartedEvent is emitted
- Add ToolCallResultEvent to ag_ui.core imports in _agent_run.py

* Apply pre-commit auto-fixes
* fix(ag-ui): address PR review feedback for #4589
1. _resolve_approval_responses now returns only approved results (not
rejections) so TOOL_CALL_RESULT events are emitted only for executed
tools. Rejection results are still written into message history.
2. Emit resolved TOOL_CALL_RESULT events in the no-updates fallback
RUN_STARTED path so approval results are never lost.
3. Rewrite tests to use real FunctionTool with func and
approval_mode='always_require' via StubAgent default_options,
verifying actual tool execution output in TOOL_CALL_RESULT content.
Added test for rejection not emitting TOOL_CALL_RESULT.

* Fix#4589: clean up approval resolution and add missing tests
- Extract duplicated TOOL_CALL_RESULT emission block into
_make_approval_tool_result_events helper to prevent drift
- Remove dead rejection_results construction in _resolve_approval_responses;
_replace_approval_contents_with_results already handles rejections inline
- Pass only approved_results (not all_results) to clarify the contract
- Add mixed approve/reject test validating the core splitting logic
- Add zero-updates test covering the no-updates fallback emission path
- Add direct unit test for _resolve_approval_responses return value

* Python: Emit AG-UI events for MCP tool calls, results, and text reasoning
Fixes#4213 — `_emit_content()` in the AG-UI layer only handled `text`,
`function_call`, `function_result`, `function_approval_request`, `usage`,
and `oauth_consent_request` content types. Foundry MCP content types
(`mcp_server_tool_call`, `mcp_server_tool_result`) and `text_reasoning`
fell through unhandled, producing no SSE events for AG-UI consumers.
Added three new handler functions wired into `_emit_content()`:
- `_emit_mcp_tool_call`: emits TOOL_CALL_START + TOOL_CALL_ARGS and
tracks in FlowState for MESSAGES_SNAPSHOT inclusion
- `_emit_mcp_tool_result`: emits TOOL_CALL_END + TOOL_CALL_RESULT with
full FlowState cleanup mirroring `_emit_tool_result`
- `_emit_text_reasoning`: emits the protocol-defined reasoning event
sequence (ReasoningStart → MessageStart → MessageContent → MessageEnd
→ ReasoningEnd) with ReasoningEncryptedValueEvent for protected_data
* Add HTTP round-trip tests for MCP tool and reasoning SSE events
Exercises the full POST → SSE bytes → parse → validate pipeline for
mcp_server_tool_call, mcp_server_tool_result, text_reasoning, and
ReasoningEncryptedValueEvent content through FastAPI TestClient.
* Fix _emit_mcp_tool_result missing predictive_handler support (#4213)
- Add predictive_handler parameter to _emit_mcp_tool_result and mirror
the apply_pending_updates + StateSnapshotEvent block from _emit_tool_result
- Forward predictive_handler from _emit_content to _emit_mcp_tool_result
- Add assertion for stored arguments in MCP tool call test
- Add test for predictive handler state snapshot after MCP tool result

responses client, which passes detail through unconditionally.
Also add test coverage for:
- Future/unknown string detail values being passed through
- Data URI images (covering the 'data' branch of the match)

* Fix zero-argument MCP tool schema missing 'properties' key (#4540)
MCP servers for zero-argument tools (e.g. matlab-mcp-core-server's
detect_matlab_toolboxes) declare inputSchema as {"type": "object"}
without a "properties" key. OpenAI's API requires "properties" to
be present on object schemas, causing a 400 invalid_request_error.
Normalize inputSchema at MCP ingestion in load_tools() to inject an
empty "properties": {} when it is missing from object-type schemas.

* Fix A2AAgent to invoke context providers before and after run
A2AAgent.run() bypassed the context provider lifecycle (before_run/after_run)
that BaseAgent defines as a contract for all agents. This caused A2AAgent to
violate the semantic definition of BaseAgent, resulting in inconsistency with
other agent implementations.
The fix follows the same pattern used by WorkflowAgent:
- Create SessionContext and run before_run on all context providers before
processing the A2A stream
- Collect response updates and run after_run on all context providers after
the stream is fully consumed
- Auto-create a session when context providers are configured but no session
is explicitly passed

* Python: Re-read env vars in configure_otel_providers and enable_instrumentation (#4119)
Fix ENABLE_SENSITIVE_DATA and VS_CODE_EXTENSION_PORT env vars being ignored
when load_dotenv() runs after module import. The module-level
OBSERVABILITY_SETTINGS singleton cached env state at import time, and
configure_otel_providers() / enable_instrumentation() never re-read from
os.environ when parameters were None.
Both functions now construct a fresh ObservabilitySettings() to pick up
current env vars when explicit parameters are not provided, matching the
existing behavior of the env_file_path branch.
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* Address PR review feedback for #4119: avoid throwaway ObservabilitySettings
- Add _read_bool_env/_read_int_env helpers to read env vars without
constructing a full ObservabilitySettings (which calls create_resource())
- Replace ObservabilitySettings() in enable_instrumentation() and
configure_otel_providers() else-branch with direct env reads
- Add enable_console_exporters parameter to configure_otel_providers()
for override parity with enable_sensitive_data and vs_code_extension_port
- Propagate _resource and _executed_setup in the non-env_file_path branch
- Make existing tests hermetic (clear VS_CODE_EXTENSION_PORT and
ENABLE_CONSOLE_EXPORTERS env vars)
- Add tests: enable_console_exporters env refresh, explicit param overrides
for both enable_instrumentation() and configure_otel_providers()

* Address remaining review feedback for #4119

by clearing ENABLE_CONSOLE_EXPORTERS from the environment

cover the new refresh behavior

* Remove unconditional enable_console_exporters overwrite from enable_instrumentation() (#4119)
enable_instrumentation() is documented as not configuring exporters, so
managing enable_console_exporters there was a leaky abstraction. The
unconditional _read_bool_env call silently reset the value to False when
ENABLE_CONSOLE_EXPORTERS was absent from env, clobbering any value
previously set by configure_otel_providers(enable_console_exporters=True).
- Remove the unconditional overwrite line from enable_instrumentation()
- Replace test_enable_instrumentation_reads_env_console_exporters with
test_enable_instrumentation_does_not_touch_console_exporters
- Add regression test: enable_instrumentation() does not clobber a
previously configured enable_console_exporters value
- Add test: explicit enable_sensitive_data param still leaves
enable_console_exporters untouched

* Fix GetExecutorName to handle agent names with underscores
Split on last underscore instead of first, and validate that the
suffix is a 32-char hex string (sanitized GUID) before stripping it.
This prevents truncation of agent names like 'my_agent' when the
executor ID is 'my_agent_<guid>'.

* Fix _deduplicate_messages catch-all branch dropping valid repeated messages (#4682)
Remove the catch-all dedup branch that used (role, hash(content_str)) as a
dedup key. This incorrectly treated any two messages with the same role and
identical content as duplicates, dropping valid repeated messages (e.g., a
user saying 'yes' to confirm two separate things).
The tool-specific dedup branches (tool results by call_id, assistant tool
calls by call_id tuple) remain unchanged as they correctly identify true
protocol-level duplicates.

* Address review: consecutive-duplicate detection for non-tool messages (#4682)
- Replace blanket dedup removal with consecutive-duplicate detection:
only skip a message if the immediately preceding message has the same
role and content, preserving protection against upstream replays while
allowing identical messages at different conversation points.
- Strengthen test assertions to verify message identity and order, not
just list length.
- Add tests for consecutive duplicate skipping, non-consecutive
preservation, and messages with contents=None.

* Apply pre-commit auto-fixes
* Use message_id for deduplication instead of content hashing
Deduplicate general messages by message_id when available, replacing
the consecutive-duplicate content check. Two messages with the same id
are definitively the same message (upstream replay), while identical
content with distinct ids (e.g. repeated "yes" confirmations) is
preserved. Messages without a message_id are always kept.
* Fix message_id dedup: truthy check, content-hash fallback, log safety
- Use truthy check (`if msg.message_id`) instead of `is not None` so
empty-string IDs fall through to content-hash dedup rather than
collapsing unrelated messages.
- Add content-hash fallback for messages without message_id, preventing
false negatives from integrations that don't set IDs.
- Remove raw message_id from log format string (addresses log-injection
surface with control characters).
- Add tests for empty-string message_id edge cases.
- Update existing tests to reflect content-hash dedup behavior.

* Python: clean up kwargs across agents, chat clients, tools, and sessions (#3642)
Audit and refactor public **kwargs usage across core agents, chat clients,
tools, sessions, and provider packages per the migration strategy codified
in CODING_STANDARD.md.
Key changes:
- Add explicit runtime buckets: function_invocation_kwargs and client_kwargs
on RawAgent.run() and chat client get_response() layers.
- Refactor FunctionTool to prefer explicit ctx: FunctionInvocationContext
injection; legacy **kwargs tools still work via _forward_runtime_kwargs.
- Refactor Agent.as_tool() to use direct JSON schema, always-streaming
wrapper, approval_mode parameter, and UserInputRequiredException
propagation (integrates PR #4568 behavior).
- Remove implicit session bleeding into FunctionInvocationContext; tools
that need a session must receive it via function_invocation_kwargs.
- Lower chat-client layers after FunctionInvocationLayer accept only
compatibility **kwargs (client_kwargs flattened, function_invocation_kwargs
ignored).
- Add layered docstring composition from Raw... implementations via
_docstrings.py helper.
- Clean up provider constructors to use explicit additional_properties.
- Deprecation warnings on legacy direct kwargs paths.
- Update samples, tests, and typing across all 23 packages.

* Python: A2AAgent defaults name/description from AgentCard
When an AgentCard is provided but name/description are not explicitly
set, A2AAgent now falls back to agent_card.name and agent_card.description.

especially in GroupChat orchestrations where name and description are
essential for routing decisions.
Explicit values still take precedence over card values.

Bedrock's Converse API only accepts "auto", "any", or "tool" as valid
toolChoice keys. The previous code mapped tool_choice="none" to
{"none": {}}, which causes a botocore.exceptions.ParamValidationError.
When tool_choice="none" (set by FunctionInvocationLayer after exhausting
max iterations), the fix now omits toolConfig entirely so the model
won't attempt tool calls.
Added tests for tool_choice="none", "auto", and "required" modes.

* Use deepcopy for state snapshot to detect nested mutations (#4500)
Replace dict() shallow copy with copy.deepcopy() when snapshotting
workflow state before activity execution. The shallow copy shared
references to nested objects (dicts, lists), so in-place mutations by

an empty diff and preventing state updates from propagating to
downstream activities.

The DevUI /v1/responses endpoint accepts function_approval_response content
without verifying that the request_id corresponds to a real pending approval
request issued by the server. This allows forged approval responses to
execute arbitrary tools with attacker-controlled arguments, bypassing
approval_mode='always_require'.
Changes:
- Track outgoing approval requests in a server-side registry
(_pending_approvals) keyed by request_id
- Validate incoming approval responses against this registry; reject
any response whose request_id was not issued by the server
- Use server-stored function_call data (tool name, arguments, call_id)
instead of client-supplied data when constructing the approval response
- Consume request_ids on use (pop from registry) to prevent replay attacks
Tests:
- 8 new tests covering forged rejection, server-data enforcement,
anti-replay, multiple independent approvals, and edge cases

- Validate rejected approval responses against pending_approvals registry,
not just approved ones. Fabricated rejections without a prior request are
now stripped from messages before reaching the LLM.
- Bound _pending_approvals with OrderedDict + LRU eviction (max 10k) to
prevent unbounded memory growth from abandoned approval requests.
- Skip registration when function_call.name is None/empty; log warning
when content.id or function_call is missing at registration time.
- Document pending_approvals parameter in run_agent_stream docstring.
- Add test for fabricated rejection attack scenario.
- Assert pending approval entry is preserved after function name mismatch.
- Pre-populate pending_approvals in rejection test for correct validation.

* Extract function_approval_response from workflow messages (#4546)
_extract_responses_from_messages now handles function_approval_response

* Decouple __deepcopy__ from DEFAULT_EXCLUDE in SerializationMixin (#4455)
Introduce _SHALLOW_COPY_FIELDS class variable in SerializationMixin to
separate deep-copy semantics from serialization semantics. Previously,
__deepcopy__ used DEFAULT_EXCLUDE to decide which fields to shallow-copy,
conflating 'not serialized' with 'not safe to deep-copy'. A field added
to DEFAULT_EXCLUDE purely for serialization (e.g. additional_properties)
would be silently shared between original and copy.

* fix: prevent pickle deserialization of untrusted HITL input
Add strip_pickle_markers() to sanitize HTTP input before it reaches
pickle.loads() via the checkpoint decoding path. Applied as a 3-layer
defence-in-depth:
1. _app.py: sanitize req.get_json() at the HTTP boundary
2. _workflow.py: sanitize in _deserialize_hitl_response() before decode
3. _serialization.py: sanitize in reconstruct_to_type() as final guard
Any dict containing __pickled__ or __type__ markers from untrusted
sources is replaced with None, blocking arbitrary code execution via
crafted payloads to POST /workflow/respond/{instanceId}/{requestId}.

untrusted HITL data now returns as-is when no type hint is available,
never flowing into pickle.loads().
2. Move strip_pickle_markers() out of reconstruct_to_type() the function
is general-purpose again; untrusted-data callers are responsible for
sanitizing first (documented with NOTE comment).
3. Define _PICKLE_MARKER/_TYPE_MARKER as local constants with import-time
assertions against core's values decouples from private names while
failing loudly if core ever changes them.
4. Update tests to reflect new responsibility boundaries.
* fix: simplify warning message and fix ruff RUF001 lint
* fix: suppress pyright reportPrivateUsage on core marker imports
* Lower marker-strip log from warning to debug to avoid log flooding
* Replace assert with RuntimeError for marker sync checks (ruff S101)
* Fix pyright and ruff CI errors in security fix
- Use cast() for dict/list comprehensions in strip_pickle_markers (pyright)
- type: ignore for narrowed dict return in _workflow.py (pyright)
- Simplify marker imports: use core constants directly, remove local copies
- Remove duplicate pyright ignore comment
* Remove duplicate end-to-end test in TestStripPickleMarkers
* Suppress mypy redundant-cast on list cast needed by pyright
* Initial plan
* Fix broken Strands Agents documentation links in ADR 0001
Replace 5 broken strandsagents.com URLs (returning 404) with stable
GitHub source code links in docs/decisions/0001-agent-run-response.md.
The Strands Agents docs site restructured from /api-reference/python/
to /api/python/, breaking the old links.

* Skip flaky CodeInterpreter integration tests in CI
The CreateAgent_CreatesAgentWithCodeInterpreter tests fail intermittently
because the Azure AI Code Interpreter service sometimes fails to read/execute
uploaded Python files. This causes all 4 integration test jobs to fail
consistently across both platforms (ubuntu/windows) and TFMs (net10.0/net472).
Mark both test variants with Skip to match the convention used by other
flaky tests in the suite (e.g., AzureAIAgentsPersistentStructuredOutputRunTests).

* Python: Add A2A server sample and fix client streaming bug
Add a pure Python A2A server sample so testing the A2A client no longer
requires running the .NET server. The server uses the a2a-sdk's
A2AStarletteApplication with uvicorn and supports three agent types
(invoice, policy, logistics) backed by AzureOpenAIResponsesClient.
New files:
- a2a_server.py: Main server entry point with CLI args
- agent_executor.py: Bridges a2a-sdk AgentExecutor to Agent Framework
- agent_definitions.py: Agent and AgentCard factory definitions
- invoice_data.py: Mock invoice data and query tool functions
- a2a_server.http: REST Client requests for testing
Also fixes a streaming bug in agent_with_a2a.py where async with was
used on ResponseStream which does not support the async context manager
protocol. Changed to async for to match all other samples.

* Auto-finalize ResponseStream on iteration completion
When a ResponseStream is fully consumed via async iteration,
automatically trigger finalization (finalizer + result hooks).
This ensures session history is persisted in streaming multi-turn
conversations without requiring an explicit get_final_response() call.
- Add auto-finalize call in __anext__ on StopAsyncIteration
- Guard inner stream finalization to prevent double-execution
- Re-check _finalized after iteration in get_final_response()
- Add tests for auto-finalization and streaming session history
- Revert sample file renames from previous commit

* Python: Exclude conversation_id from chat completions options (#4315)
When a session with service_session_id is passed to an agent using the
Chat Completions client, conversation_id leaked through _prepare_options()
into AsyncCompletions.create(), causing an 'unexpected keyword argument'
error. The Responses client already excluded conversation_id but the Chat
Completions client did not.
Added conversation_id to the exclusion set in _prepare_options().

* Fix#4305: Handle dict chat_options in _update_conversation_id
_update_conversation_id assumed chat_options had attribute access, but
ChatOptions is a TypedDict (dict). When a dict was passed, setting
.conversation_id raised AttributeError. Now checks isinstance(dict) and
uses key access for dicts, falling back to attribute access for objects.

* Address PR feedback: use Mapping ABC and add missing tests (#4305)
- Use collections.abc.Mapping instead of dict for isinstance check in
_update_conversation_id, making it more robust for non-dict mapping types.
- Add test for object-style chat_options with optional options dict parameter.
- Add test verifying existing conversation_id gets overwritten (idempotent).

* Remove unnecessary Mapping check in _update_conversation_id (#4305)
chat_options is always a dict, so the isinstance(chat_opts, Mapping)

* .NET: Fixing issue where OpenTelemetry span is never exported in .NET in-process workflow execution (#4196)
* 1. Add reproduction test for issue #4155: workflow.run Activity never stopped in streaming OffThread path
The WorkflowRunActivity_IsStopped_Streaming_OffThread test demonstrates that
the workflow.run OpenTelemetry Activity created in StreamingRunEventStream.RunLoopAsync
is started but never stopped when using the OffThread/Default streaming execution.
The background run loop keeps running after event consumption completes, so the
using Activity? declaration never disposes until explicit StopAsync() is called.

2. Fix workflow.run Activity never stopped in streaming OffThread execution (#4155)
The workflow.run OpenTelemetry Activity in StreamingRunEventStream.RunLoopAsync
was scoped to the method lifetime via 'using'. Since the run loop only exits on
cancellation, the Activity was never stopped/exported until explicit disposal.
Fix: Remove 'using' and explicitly dispose the Activity when the workflow reaches
Idle status (all supersteps complete). A safety-net disposal in the finally block
handles cancellation and error paths.

* Add root-level workflow.session activity spanning run loop lifetime\n\nImplements two-level telemetry hierarchy per PR feedback from lokitoth:\n- workflow.session: spans the entire run loop / stream lifetime\n- workflow_invoke: per input-to-halt cycle, nested within the session\n\nThis ensures the session activity stays open across multiple turns,\nwhile individual run activities are created and disposed per cycle.\n\nAlso fixes linkedSource CancellationTokenSource disposal leak in\nStreamingRunEventStream (added using declaration)."
* Address Copilot review: fix Activity/CTS disposal, rename activity, add error tag\n\n1. LockstepRunEventStream: Remove 'using' from Activity in async iterator\n and manually dispose in finally block (fixes#4155 pattern). Also dispose\n linkedSource CTS in finally to prevent leak.\n2. Tags.cs: Add ErrorMessage (\"error.message\") tag for runtime errors,\n distinct from BuildErrorMessage (\"build.error.message\").\n3. ActivityNames: Rename WorkflowRun from \"workflow_invoke\" to \"workflow.run\"\n for cross-language consistency.\n4. WorkflowTelemetryContext: Fix XML doc to say \"outer/parent span\" instead\n of \"root-level span\".\n5. ObservabilityTests: Assert WorkflowSession absence when DisableWorkflowRun\n is true.\n6. WorkflowRunActivityStopTests: Fix streaming test race by disposing\n StreamingRun before asserting activities are stopped.\n7. StreamingRunEventStream/LockstepRunEventStream: Use Tags.ErrorMessage\n instead of Tags.BuildErrorMessage for runtime error events."
* Review fixes: revert workflow_invoke rename, use 'using' for linkedSource, move SessionStarted earlier\n\n- Revert ActivityNames.WorkflowRun back to \"workflow_invoke\" (OTEL semantic convention contract)\n- Use 'using' declaration for linkedSource CTS in LockstepRunEventStream (no timing sensitivity)\n- Move SessionStarted event before WaitForInputAsync in StreamingRunEventStream to match Lockstep behavior"
* Improve naming and comments in WorkflowRunActivityStopTests"
* Prevent session Activity.Current leak in lockstep mode, add nesting test
Save and restore Activity.Current in LockstepRunEventStream.Start() so the
session activity doesn't leak into caller code via AsyncLocal. Re-establish
Activity.Current = sessionActivity before creating the run activity in
TakeEventStreamAsync to preserve parent-child nesting.
Add test verifying app activities after RunAsync are not parented under the
session, and that the workflow_invoke activity nests under the session."

* Python: Add propagate_session parameter to as_tool() for session sharing
Add opt-in session propagation in agent-as-tool scenarios. When
propagate_session=True, the parent agent's AgentSession is forwarded
to the sub-agent's run() call, allowing both agents to share session
state (history, metadata, session_id).
- Add propagate_session parameter to BaseAgent.as_tool() (default False)
- Include session in additional_function_arguments so it flows to tools
- Add 3 tests for propagation on/off and shared state verification

* Fix flaky test: prevent spurious workflow_invoke Activity on timeout wake-up
The StreamingRunEventStream run loop uses a 1-second timeout on
WaitForInputAsync. When the timeout fires before the consumer calls
StopAsync, the loop would create a spurious workflow_invoke Activity
even though no actual input was provided. This caused the
WorkflowRunActivity_IsStopped_Streaming_OffThread_MultiTurnAsync test
to intermittently fail (expecting 2 activities but finding 3).
Fix: guard the loop body with a HasUnprocessedMessages check. On
timeout wake-ups with no work, the loop waits again without creating
an activity or changing the run status.

* Fix epoch race condition causing unit tests to hang on net10.0 and net472
The HasUnprocessedMessages guard (previous commit) correctly prevents
spurious workflow_invoke Activity creation on timeout wake-ups, but
exposed a latent race in the epoch-based signal filtering.
The race: when the run loop processes messages quickly and calls
Interlocked.Increment(ref _completionEpoch) before the consumer calls
TakeEventStreamAsync, the consumer reads the already-incremented epoch
and sets myEpoch = epoch + 1. This causes the consumer to skip the
valid InternalHaltSignal (its epoch < myEpoch) and block forever
waiting for a signal that will never arrive (since the guard prevents
spurious signal generation).
Fix: read _completionEpoch without +1. The +1 was originally needed to
filter stale signals from timeout-driven spurious loop iterations, but
those no longer exist thanks to the HasUnprocessedMessages guard.

is a pre-existing issue in the declarative workflow multi-turn test logic.

* Fix#4321: Set CurrentUICulture to en-US in PowerFx eval()
On non-English systems, CultureInfo.CurrentUICulture causes PowerFx to
emit localized error messages. The existing ValueError guard only matches
English strings ("isn't recognized", "Name isn't valid"), so undefined
variable errors crash instead of returning None gracefully.
Fix: save and restore CurrentUICulture alongside CurrentCulture before
calling engine.eval(), ensuring error messages are always in English.

* Fix: Parse oauth_consent_request events in Azure AI client (#3950)
When Azure AI Agent Service returns an oauth_consent_request output item
for OAuth-protected MCP tools, the base OpenAI responses parser drops it
(hits case _ default branch). This causes agent runs to complete silently
with zero content.
Changes:
- Add oauth_consent_request ContentType and Content.from_oauth_consent_request()
factory with consent_link field and user_input_request=True
- Override _parse_response_from_openai and _parse_chunk_from_openai in
RawAzureAIClient to intercept Azure-specific oauth_consent_request items
- Add _emit_oauth_consent helper in AG-UI to emit CustomEvent for frontends
- Add tests proving base parser drops the event and Azure AI override catches it

* Fix#4371: Propagate session to manager agent in StandardMagenticManager
StandardMagenticManager._complete() was calling self._agent.run(messages)
without passing a session. This caused context providers (e.g.
RedisHistoryProvider) configured on the manager agent to silently fail,
as each call created a new ephemeral session with a different session_id.
Changes:
- Create an AgentSession in StandardMagenticManager.__init__()
- Pass session=self._session in _complete() calls to agent.run()
- Persist/restore the session in checkpoint save/restore methods
- Add regression tests for session propagation and checkpoint round-trip

* Fix IndexError when reasoning models return no text content (#4384)
In _prepare_message_for_openai(), the text_reasoning case unconditionally
accessed all_messages[-1] to attach reasoning_details. When a reasoning
model (e.g. gpt-5-mini) returns reasoning_details without text content,
all_messages is empty, causing an IndexError.
Guard the access by initializing all_messages with the current args dict
when it is empty, so reasoning_details can be safely attached.

* Address review: buffer reasoning details for valid message payloads (#4384)
- Buffer pending reasoning details and attach to the next message with
content/tool_calls, avoiding standalone reasoning-only messages.
- When reasoning is the only content, emit a message with empty content
to satisfy Chat Completions schema requirements.
- Strengthen test assertions to verify text+reasoning co-location and
that all messages with reasoning_details also have content or tool_calls.

content consumed it

Add tests verifying that when workflow.run() is called with a dict or string
input, the Entry node (JoinExecutor with kind: 'Entry') correctly initializes
Workflow.Inputs via _ensure_state_initialized so that:
- Expressions like =inputs.age resolve to the correct value
- Conditions like =Local.age < 13 evaluate based on actual input (not blank/0)

* Revert _workflow.py yield-inside-context-manager changes
Moving yield inside `with _framework_event_origin()` blocks in the
async generator causes ContextVar token reset failures on Python 3.12
Windows. The token stays un-reset while the generator is suspended,
and async generator finalization in a different contextvars.Context
triggers ValueError, corrupting OpenTelemetry span state and causing
test_span_creation_and_attributes to see leaked spans.
Keep yields outside the context manager blocks to ensure tokens are
reset immediately before the generator suspends.

* fix: handle thread.message.completed event in Assistants API streaming
Previously, `thread.message.completed` events fell through to the
catch-all `else` branch and yielded empty `ChatResponseUpdate` objects,
silently discarding fully-resolved annotation data (file citations,
file paths, and their character-offset regions).
This commit adds a dedicated handler for `thread.message.completed`
that:
- Walks the completed ThreadMessage.content array
- Extracts text blocks with their fully-resolved annotations
- Maps FileCitationAnnotation and FilePathAnnotation to the
framework's Annotation type with proper TextSpanRegion data
- Yields a ChatResponseUpdate containing the complete text and
annotations
Fixes#4322
* test: add tests for thread.message.completed annotation handling
Tests cover:
- File citation annotation extraction
- File path annotation extraction
- Multiple annotations on a single text block
- Text-only messages (no annotations)
- Non-text blocks are skipped
- Mixed content blocks (text + image)
- Conversation ID propagation
* fix: address Copilot review - add quote field and log unrecognized annotations
- Include `quote` from `annotation.file_citation.quote` in
`additional_properties` for FileCitationAnnotation, preserving the
exact cited text snippet from the source file
- Add `else` clause to log unrecognized annotation types at debug level,
consistent with the pattern in `_responses_client.py`
- Add `import logging` and module-level logger
* test: add coverage for quote field and unrecognized annotation logging
- test_message_completed_with_file_citation_quote: verifies quote is
included in additional_properties
- test_message_completed_with_file_citation_no_quote: verifies quote
is omitted when None
- test_message_completed_unrecognized_annotation_logged: verifies
unknown annotation types are logged at debug level and skipped
* fix: address reviewer nits — logger name convention + annotation type string
Per @giles17's review:
- Use logging.getLogger('agent_framework.openai') to match module convention
- Simplify debug message to use annotation.type instead of type().__name__
* refactor: move message.completed tests into consolidated test file
Per @giles17's review: moved all tests from test_assistants_message_completed.py
into test_openai_assistants_client.py and deleted the standalone file.
* fix: resolve mypy no-redef and ruff RET504 lint errors
- Remove duplicate type annotation for 'ann' variable (no-redef)
- Return directly from fixture instead of unnecessary assignment (RET504)
* fix: rename annotation variable in completed block to fix mypy type conflict
The 'annotation' loop variable in thread.message.completed has type
FileCitationAnnotation | FilePathAnnotation, which conflicts with the
delta block's 'annotation' of type FileCitationDeltaAnnotation |
FilePathDeltaAnnotation. Renamed to 'completed_annotation' to avoid
mypy 'Incompatible types in assignment' error.
* fix: remove quote field from FileCitationAnnotation handling

* fix(python): use AgentResponse.value instead of model_validate_json in HITL sample
Since the agent is configured with response_format=GuessOutput, the
AgentResponse already provides .value with the parsed Pydantic model.
Using .value is more idiomatic and avoids redundant JSON parsing.
Fixes#4396
* fix: add safety guard for AgentResponse.value being None
Address Copilot review feedback: .value is optional and may be None
if response_format isn't propagated through the streaming path.
Add an explicit None check with a clear error message.
* Skip tool validation when UseProvidedChatClientAsIs is true (#3855)
When GetAIAgentAsync is called with ChatClientAgentOptions.UseProvidedChatClientAsIs = true,

* Decouple tool matching from validation and add tool preservation test (#3855)
Always match provided AIFunctions to server-side function definitions
regardless of requireInvocableTools flag. Only throw when validation
is required and no match is found. This ensures UseProvidedChatClientAsIs
still preserves user-provided AIFunction tools instead of falling back
to the broken ResponseToolAITool wrapper.

When __future__ annotations are enabled, type annotations are stored as
strings. The handler decorator was passing these strings directly to
validate_workflow_context_annotation, which uses typing.get_origin and
returns None for strings, causing a ValueError.

WorkflowAgent._run_impl() and _run_stream_impl() did not set
session_context._response before calling _run_after_providers().
This caused InMemoryHistoryProvider.after_run() to see context.response
as None, so response messages were never stored in the session.
On subsequent runs, the workflow only received prior user inputs without
assistant responses, breaking multi-turn conversations.
Fix: Set session_context._response to the workflow result before running
after_run providers, matching the behavior of the regular Agent class.

* fix(python): preserve workflow run kwargs on response continuation (#4293)
When continuing a paused workflow with run(responses=...), the existing
run kwargs stored in state were unconditionally overwritten with an empty
dict. This caused subsequent agent invocations to lose the original run
context (e.g., custom_data, user tokens).
Now kwargs are only overwritten when:
- New kwargs are explicitly provided (override), or
- State was just cleared for a fresh run (initialize to {})
On continuation without new kwargs, existing kwargs are preserved.

The WorkflowRunActivity_IsStopped_Streaming_OffThread test demonstrates that
the workflow.run OpenTelemetry Activity created in StreamingRunEventStream.RunLoopAsync

The workflow.run OpenTelemetry Activity in StreamingRunEventStream.RunLoopAsync
was scoped to the method lifetime via 'using'. Since the run loop only exits on

Fix: Remove 'using' and explicitly dispose the Activity when the workflow reaches
Idle status (all supersteps complete). A safety-net disposal in the finally block
handles cancellation and error paths.

* fix: use HasSchema check in DetermineElementType to prevent empty records
When parsing JSON arrays containing objects without a predefined schema,
`DetermineElementType()` was creating a `VariableType` with an empty
(non-null) schema via `targetType.Schema?.Select(...) ?? []`. This caused
`ParseRecord` to take the schema-based parsing path, iterating over zero
schema fields and silently discarding all JSON properties.
The fix checks `targetType.HasSchema` and falls back to
`VariableType.RecordType` (which has `Schema = null`) when no schema is
defined, ensuring `ParseRecord` takes the dynamic `ParseValues()` path
that preserves all JSON properties.
Closes#4195
* test: add regression tests for schema-less JSON array-of-objects parsing (#4195)
Add two regression tests to JsonDocumentExtensionsTests:
1. ParseRecord_ObjectWithArrayOfObjects_NoSchema_PreservesNestedProperties
- Parses a JSON object containing an array of objects using
VariableType.RecordType (no schema) and verifies that nested
object properties (name, role) are preserved in each element.
- This is the exact scenario from issue #4195 where objects in
arrays were being returned as empty dictionaries.
2. ParseList_ArrayOfObjects_NoSchema_PreservesProperties
- Parses a JSON array of objects directly via ParseList with
VariableType.ListType (no schema) and verifies all properties
are preserved.
Both tests follow the existing Arrange/Act/Assert pattern and would
have failed before the DetermineElementType() fix (empty dictionaries
instead of populated ones).
* Fix thread corruption when max_iterations exhausted (#1366)
When the function invocation loop exhausts max_iterations while the model
keeps requesting tools, the failsafe code path (calling the model with
tool_choice='none' and prepending fcc_messages) was unreachable because
'if response is not None: return response' short-circuited before it.
The fix removes the premature return so the failsafe always runs after
loop exhaustion, making a final model call with tool_choice='none' to
produce a clean text answer and prepending accumulated fcc_messages from
prior iterations. This matches the existing pattern used by the error
threshold and max_function_calls paths.
Also unskips test_max_iterations_limit and test_streaming_max_iterations_limit
which were previously skipped with 'needs investigation in unified API'.

* fix: prevent doubled tool_call arguments in MESSAGES_SNAPSHOT
When streaming with client-side tools, some providers send a full-
arguments replay after the streaming deltas complete. The `_emit_tool_call`
function unconditionally appends every arguments delta to the internal
`flow.tool_calls_by_id` tracking dictionary via `+=`. When the replay
contains the exact same complete arguments string that was already
accumulated from prior deltas, the arguments get doubled (e.g.,
`{"todoText":"buy groceries"}{"todoText":"buy groceries"}`).
This causes `MESSAGES_SNAPSHOT` events to contain invalid doubled JSON in
`tool_calls[].function.arguments`, breaking any client or middleware that
relies on snapshots for state reconstruction.
The fix adds a guard (mirroring the existing duplicate guard in
`_emit_text`) that detects when the incoming delta exactly equals the
already-accumulated arguments string, indicating a full-arguments replay
rather than an incremental delta. In this case the append is skipped,
preventing the doubling.
The `ToolCallArgsEvent` deltas are still emitted correctly for real-time
streaming — only the internal snapshot accumulator is guarded.
Fixes#4194
* fix: move duplicate check before event emission + add test
Address Copilot review feedback:
1. Move duplicate full-arguments replay detection BEFORE emitting
ToolCallArgsEvent, for consistency with _emit_text() which returns
early without emitting any events on replay detection.
2. Add test_emit_tool_call_skips_duplicate_full_arguments_replay() to
verify the duplicate detection behavior for tool call arguments,
matching the existing test pattern for text content.

* feat(python): Add embedding abstractions and OpenAI implementation (Phase 1)
This PR contains two parts:
1. **Overall migration plan** for porting vector stores and embeddings from
Semantic Kernel to Agent Framework (docs/features/vector-stores-and-embeddings/README.md)
covering all 10 phases from core abstractions through connectors and TextSearch.
2. **Phase 1 implementation** — core embedding abstractions and OpenAI/Azure OpenAI
embedding clients:
Core types (_types.py):
- EmbeddingGenerationOptions TypedDict (total=False)
- Embedding[EmbeddingT] generic class with model_id, dimensions, created_at
- GeneratedEmbeddings[EmbeddingT, EmbeddingOptionsT] list container with options, usage
- EmbeddingInputT (default str) and EmbeddingT (default list[float]) TypeVars
Protocol + base class (_clients.py):
- SupportsGetEmbeddings protocol — Generic[EmbeddingInputT, EmbeddingT, OptionsContraT]
- BaseEmbeddingClient ABC — Generic[EmbeddingInputT, EmbeddingT, OptionsCoT]
Telemetry (observability.py):
- EmbeddingTelemetryLayer with gen_ai.operation.name = "embeddings"
OpenAI implementation (openai/_embedding_client.py):
- RawOpenAIEmbeddingClient, OpenAIEmbeddingClient, OpenAIEmbeddingOptions
- Uses _ensure_client() factory pattern
Azure OpenAI implementation (azure/_embedding_client.py):
- AzureOpenAIEmbeddingClient following AzureOpenAIChatClient pattern
- Supports API key, Entra ID credentials, env var configuration
Tests:
- 47 unit tests for types, protocol, base class, OpenAI, and Azure clients
- 6 integration tests (gated behind RUN_INTEGRATION_TESTS + credentials)
Samples:
- samples/02-agents/embeddings/openai_embeddings.py

Add a new per-request max_function_calls setting to FunctionInvocationConfiguration
that limits the total number of individual function invocations across all iterations

* Fix system message content sent as list instead of string
Some OpenAI-compatible endpoints (e.g. NVIDIA NIM) reject system messages
when content is a list of content parts. This change flattens system and
developer message content to a plain string in the Chat Completions client.

* Fix compatibility with opentelemetry-semantic-conventions-ai 0.4.14
Version 0.4.14 removed several LLM_* attributes from SpanAttributes
(LLM_SYSTEM, LLM_REQUEST_MODEL, LLM_RESPONSE_MODEL, LLM_REQUEST_MAX_TOKENS,
LLM_REQUEST_TEMPERATURE, LLM_REQUEST_TOP_P, LLM_TOKEN_TYPE).
Move these to the OtelAttr enum with their well-known gen_ai.* string values
and update all references in observability.py and tests.

* Flatten text-only message content to string for all roles
Extend the system/developer fix to all message roles. Text-only content
lists are now post-processed into plain strings, while multimodal content
(text + images/audio) remains as a list. This fixes compatibility with
OpenAI-like endpoints that cannot deserialize list content (e.g. Foundry
Local's Neutron backend).

* fix: strip function_call and text_reasoning from cross-agent workflow handoff
When a reasoning model (e.g. gpt-5-mini) runs as Agent 1 in a workflow, its
response includes text_reasoning items (with server-scoped IDs like rs_XXXX)
and function_call items. Forwarding these to Agent 2 in a fresh conversation
caused API errors because the reasoning/call IDs are scoped to the original
stored response context.
Changes:
- Strip 'function_call', 'text_reasoning', 'function_approval_request', and
'function_approval_response' from handoff messages in _agent_executor.py
- Keep 'function_result' so the actual tool output content is preserved for
the next agent's context
- Update unit tests to reflect that function_result messages survive handoff
(messages grow from 2→3: user, tool(result), assistant(summary))
- Fix incorrect test assertions in test_function_invocation_stop_clears_*
that assumed the client layer updates session.service_session_id
- Also fixed _extract_function_calls to search all messages with call_id
deduplication, and the error-limit stop path to submit function_call_output
items before halting (via tool_choice=none cleanup call)

* fix: reasoning model workflow handoff and history serialization
Fixes multiple related issues when using reasoning models (gpt-5-mini,
gpt-5.2) in multi-agent workflows that chain agents via from_response
or replay full conversation history via AgentExecutorRequest.
## Reasoning items always emitted on output_item.added
When a reasoning model produces encrypted or hidden reasoning (no
visible text), the Responses API still fires a reasoning output item
without any reasoning_text.delta events. Previously no text_reasoning
Content was emitted in that case, making it invisible to downstream
logic. Both the non-streaming (_parse_response_from_openai) and
streaming (output_item.added) paths now always emit at least one
text_reasoning Content — with empty text if no content is available —
so co-occurrence detection and serialization guards work reliably.
## Reasoning items only serialized when paired with a function_call
The Responses API only accepts reasoning items in input when they
directly preceded a function_call in the original response. Sending a
reasoning item that preceded a text response (no tool call) causes:
"reasoning was provided without its required following item"
_prepare_message_for_openai now checks has_function_call per message
and skips text_reasoning serialization when there is no accompanying
function_call.
## summary field is an array, not an object
The reasoning item summary field sent to the Responses API must be an
array of objects ([{"type": "summary_text", "text": ...}]), not a
single object. Fixed _prepare_content_for_openai accordingly.
## service_session_id cleared when explicit history is provided
When a workflow coordinator replays a full conversation (including
function calls from a previous agent run) back to an executor via
AgentExecutorRequest or from_response, the executor's session still
held a service_session_id (previous_response_id) from the prior run.
The API then received the same function-call items twice — once from
previous_response_id (server-stored) and once from the explicit input —
causing: "Duplicate item found with id fc_...".
AgentExecutor.run (when should_respond=True) and from_response now
reset self._session.service_session_id = None before running so that
explicit input is the sole source of conversation context.

* small improvements in text reasoning
* refactor: add reset_service_session to AgentExecutorRequest for explicit history replay
Replace the implicit 'always clear service_session_id when should_respond=True'
with an explicit opt-in field on AgentExecutorRequest.
The old approach used should_respond=True as a proxy for 'full history replay',
but that conflates two distinct intents:
- Orchestrations group chat sends should_respond=True with an empty/single-message
list (not a full replay) — unnecessarily clearing service_session_id.
- HITL / feedback coordinators send the full prior conversation and truly need
a fresh service session ID to avoid duplicate-item API errors.
Changes:
- Add AgentExecutorRequest.reset_service_session: bool = False
- AgentExecutor.run only clears service_session_id when this flag is True
- AgentExecutor.from_response unchanged (always clears; always full conversation)
- Set reset_service_session=True in all full-history-replay call sites:
agents_with_HITL.py, azure_chat_agents_tool_calls_with_feedback.py,
autogen-migration round-robin coordinator, tau2 runner
- Update _FullHistoryReplayCoordinator test helper to pass the flag

* Fix handoff orchestration not passing user message to handoff target agent (#3161)
Filter out internal handoff function call and tool result messages before
passing conversation history to the target agent's LLM. These messages
confused the model into ignoring the original user question.
* Add handoff tool call filtering behavior and enhance workflow builder
- Introduced HandoffToolCallFilteringBehavior enum to specify filtering behavior for tool call contents in handoff workflows.
- Updated HandoffsWorkflowBuilder to support customizable handoff instructions and tool call filtering behavior.
- Enhanced HandoffAgentExecutor to utilize new filtering options for improved message handling during agent handoffs.
* Enhance handoff message filtering logic and add unit tests for filtering behaviors
* Refactor HandoffMessagesFilter to remove unused handoff function names and enhance filtering logic for non-handoff function calls
* Refactor HandoffMessagesFilter to streamline FilterCandidateState initialization and improve clarity
* Refactor HandoffMessagesFilter to improve filtering logic and add integration tests for handoff workflows
* fix: HandoffAgentExecutor tests
* [BREAKING] refactor: Decouple Checkpointing and Execution APIs
With this change, Checkpointing becomes an property of an IWorkflowExecutionEnvironment. This lets environments that are tightly-coupled to their CheckpointManager avoid needing to present APIs that would not work (e.g. taking in an InMemory CheckpointManager for Durable Tasks, for example)
* refactor: Normalize IsCheckpointingEnabled naming
- Rename UserNameProvider → UserMemoryProvider
- Use session state (state dict) instead of instance variables
- Use context.extend_instructions() instead of context.instructions.append()
- Use DEFAULT_SOURCE_ID class attribute

items in follow-up calls so the API has full conversation context
- Create a fresh session per call to avoid ConversationId/previous_response_id
- Use currentCallId instead of initialCallId for computer_call_output
- Clear ContinuationToken after polling to prevent stale tokens
- Remove unused initialCallId tracking variable

* Fix#3600: Pass JSON schemas through without Pydantic conversion
This change optimizes FunctionTool and MCP flows by passing JSON schemas
directly to providers without converting them to Pydantic models first.
Key changes:
- Store JSON schema as-is when supplied to FunctionTool
- Skip Pydantic model_validate for schema-supplied tools in invoke()
- Return MCP tool schemas directly without conversion
- Add comprehensive tests for schema passthrough behavior
Performance benefits:
- Eliminates expensive Pydantic model creation for supplied schemas
- Preserves exact schema structure (additionalProperties, custom fields, etc.)
- Reduces memory overhead and initialization time
Maintains backward compatibility:
- Function signature inference still uses Pydantic models
- Explicit Pydantic models passed as input_model work as before
- All existing tests pass

* Python: Replace wildcard imports with explicit imports
- Replace all 'from ... import *' with explicit symbol imports
- Add __all__ declarations to namespace packages for re-exports
- Update CODING_STANDARD.md to prohibit wildcard imports
- Maintain exported API and preserve all functionality
fixes#3605
* Refine wildcard guidance example text
* Simplify explicit exports without self-aliases
* fix: prevent repeating instructions in continued Responses API conversations
- Instructions are now only prepended to messages on the first turn
- When conversation_id/response_id exists (continuation), instructions are skipped
- Covers OpenAI and Azure Responses API paths
- Adds regression tests for all continuation scenarios
Fixes#3498
* Apply lint fixes to continuation tests
* Consolidate responses continuation tests
* PR2: Wire context provider pipeline and update all internal consumers
- Replace AgentThread with AgentSession across all packages
- Replace ContextProvider with BaseContextProvider across all packages
- Replace context_provider param with context_providers (Sequence)
- Replace thread= with session= in run() signatures
- Replace get_new_thread() with create_session()
- Add get_session(service_session_id) to agent interface
- DurableAgentThread -> DurableAgentSession
- Remove _notify_thread_of_new_messages from WorkflowAgent
- Wire before_run/after_run context provider pipeline in RawAgent
- Auto-inject InMemoryHistoryProvider when no providers configured
* fix: update all tests for context provider pipeline, fix lazy-loaders, remove old test files
* refactor: update all sample files for context provider pipeline (AgentThread→AgentSession, ContextProvider→BaseContextProvider)
* fix: update remaining ag-ui references (client docstring, getting_started sample)
* fix: make get_session service_session_id keyword-only to avoid confusion with session_id
* refactor: rename _RunContext.thread_messages to session_messages
* refactor: remove _threads.py, _memory.py, and old provider files; migrate devui to use plain message lists
* rename: remove _new_ prefix from test files
* refactor: rewrite SlidingWindowChatMessageStore as SlidingWindowHistoryProvider(InMemoryHistoryProvider)
* fix: read full history from session state directly instead of reaching into provider internals
* fix: update stale .pyi stubs, sample imports, and README references for new provider types
* fix: remove stale message_store, _notify_thread_of_new_messages, and session_id.key references in samples
* refactor: merge context_providers and sessions sample folders into sessions, remove aggregate_context_provider
* refactor: UserInfoMemory stores state in session.state instead of instance attributes
* feat: add Pydantic BaseModel support to session state serialization
Pydantic models stored in session.state are now automatically serialized
via model_dump() and restored via model_validate() during to_dict()/from_dict()
round-trips. Models are auto-registered on first serialization; use
register_state_type() for cold-start deserialization.
Also export register_state_type as a public API.
* fix mem0
* Update sample README links and descriptions for session terminology
- Replace 'thread' with 'session' in sample descriptions across all READMEs
- Update file links for renamed samples (mem0_sessions, redis_sessions, etc.)
- Fix Threads section → Sessions section in main samples/README.md
- Update tools, middleware, workflows, durabletask, azure_functions READMEs
- Update architecture diagrams in concepts/tools/README.md
- Update migration guides (autogen, semantic-kernel)
* Fix broken Redis README link to renamed sample
* Fix Mem0 OSS client search: pass scoping params as direct kwargs
AsyncMemory (OSS) expects user_id/agent_id/run_id as direct kwargs,
while AsyncMemoryClient (Platform) expects them in a filters dict.
Adds tests for both client types.
Port of fix from #3844 to new Mem0ContextProvider.
* Fix rebase issues: restore missing _conversation_state.py and checkpoint decode logic
- Add back _conversation_state.py (encode/decode_chat_messages) lost in rebase
- Fix on_checkpoint_restore to decode cache/conversation with decode_chat_messages
- Fix on_checkpoint_restore to use decode_checkpoint_value for pending requests
- Add tests/workflow/__init__.py for relative import support
- Fix test_agent_executor checkpoint selection (checkpoints[1] not superstep)
* Add STORES_BY_DEFAULT ClassVar to skip redundant InMemoryHistoryProvider injection
Chat clients that store history server-side by default (OpenAI Responses API,
Azure AI Agent) now declare STORES_BY_DEFAULT = True. The agent checks this
during auto-injection and skips InMemoryHistoryProvider unless the user
explicitly sets store=False.
* Fix broken markdown links in azure_ai and redis READMEs
* Fix getting-started samples to use session API instead of removed thread/ContextProvider API
* updates to workflow as agent
* fix group chat import

- Bump GitHub.Copilot.SDK from 0.1.18 to 0.1.23
- Add new SessionConfig properties: ReasoningEffort, Hooks, OnUserInputRequest,
WorkingDirectory, ConfigDir, InfiniteSessions
- Add missing ResumeSessionConfig properties: Model, SystemMessage,
AvailableTools, ExcludedTools, ReasoningEffort, Hooks, OnUserInputRequest,
WorkingDirectory, ConfigDir, InfiniteSessions
- Fix UserMessageDataAttachmentsItem -> UserMessageDataAttachmentsItemFile
for new polymorphic attachment API
- Add unit tests for new session config properties
* Address PR review: centralize config mapping and improve test coverage
- Extract CopySessionConfig/CopyResumeSessionConfig as internal static helpers
to eliminate duplicated mapping logic between RunCoreStreamingAsync and
CreateResumeConfig (addresses reviewer comment on drift risk)
- Add InternalsVisibleTo for unit test project
- Replace shallow constructor tests with comprehensive property-verification
tests that validate every config property is correctly copied, including
OnUserInputRequest (addresses reviewer comments on test coverage)
* Remove accidentally committed git-lfs hooks
* restructure: Python samples into progressive 01-05 layout
- 01-get-started/: 6 numbered steps (hello agent → hosting)
- 02-agents/: all agent concept samples (tools, middleware, providers, etc.)
- 03-workflows/: ALL existing workflow samples preserved as-is
- 04-hosting/: azure-functions, durabletask, a2a
- 05-end-to-end/: demos, evaluation, hosted agents
- Old files moved to _to_delete/ for review
- Added AGENTS.md with structure documentation
- autogen-migration/ and semantic-kernel-migration/ preserved at root
* fix: switch to AzureOpenAI Foundry, fix CI failures
- Switch all 01-get-started samples to AzureOpenAIResponsesClient with
Azure AI Foundry project endpoint (AZURE_AI_PROJECT_ENDPOINT +
AZURE_OPENAI_RESPONSES_DEPLOYMENT_NAME + AzureCliCredential)
- Add _to_delete/ and 05-end-to-end/ to pyrightconfig.samples.json excludes
- Fix test paths in packages/ that referenced old getting_started/ dirs:
durabletask conftest + streaming test, azurefunctions conftest,
devui conftest + capture_messages + openai_sdk_integration
- Fix workflow_as_agent_human_in_the_loop.py import (sibling import)
- Update hosting READMEs and tool comment paths
- Replace root README.md with new structure overview
- Update AGENTS.md to document Azure OpenAI Foundry as default provider
* cleanup: remove _to_delete folder, copy resource files to active dirs
All files in _to_delete/ were either:
- Exact duplicates of files in the new structure (240 files)
- Same file with only comment path updates (100 files)
- One import-fix diff (workflow_as_agent_human_in_the_loop.py)
- One superseded minimal_sample.py
Resource files (sample.pdf, countries.json, employees.pdf, weather.json)
copied to 02-agents/sample_assets/ and 02-agents/resources/ since active
samples reference them.
* fix: address PR review comments, centralize resources, remove root duplicates
- Fix type annotation in 04_memory.py (string union -> proper types)
- Fix old sample paths in observability files
- Fix grammar/spelling in observability samples
- Move sample_assets/ and resources/ to shared/ folder
- Remove 8 duplicate observability files from 02-agents root
- Update resource path references in multimodal_input and provider samples
* fix: update broken links from old getting_started paths to new structure

02-agents/, 03-workflows/, 04-hosting/, 05-end-to-end/
- Fix absolute GitHub URLs in package READMEs
- Fix broken link in ollama package README
* fix: convert absolute GitHub URLs to relative paths for link checker
Absolute URLs to python/samples/ on main branch 404 until PR merges.
Converted to relative paths that linkspector can verify locally.
* fix: update link for handoff sample moved to orchestrations/
* fix: update chatkit-integration README path from demos/ to 05-end-to-end/
* fix: update broken links in orchestrations README to match flat directory structure
* Centralize tool result parsing in FunctionTool.invoke()
- Add parse_result static method to FunctionTool that converts raw
function return values to strings at invocation time
- Add result_parser parameter to FunctionTool and @tool decorator
for custom parsing
- Remove prepare_function_call_results from all 9 consumer files
and from the public API
- Update MCPTool to parse MCP types directly to strings via
_parse_tool_result_from_mcp and _parse_prompt_result_from_mcp
- Change MCPTool parse_tool_results/parse_prompt_results type from
Literal[True] | Callable | None to Callable | None
- Remove ReturnT type parameter from FunctionTool (now single
generic ArgsT since invoke() always returns str)
- Update all subclass signatures and docstrings
Fixes#1147
* Fix test_mcp_tool_call_tool_with_meta_integration for string results
The test was still accessing result[0].additional_properties but
invoke() now returns a string, not a list of Content objects.
* Fix SIM108 lint: use binary operator for output assignment
* Fix bedrock: use FunctionTool.parse_result instead of str() fallback
str(result) turns None into literal 'None' and dicts into Python reprs
with single quotes, breaking JSON parsing. Use the shared parse_result
which handles None as '' and serializes via json.dumps.
* updated lock
* updates from feedback
* Replace Pydantic Settings with TypedDict + load_settings()
- Remove pydantic-settings dependency, add python-dotenv
- Delete _pydantic.py (AFBaseSettings, HTTPsUrl)
- Add _settings.py with generic load_settings() function, SecretString,
type coercion, and Required field validation (SettingNotFoundError)
- Convert all 13 settings classes from AFBaseSettings subclasses to
TypedDict definitions with load_settings() calls
- Update all consumers from attribute access to dict access
- Add 20 unit tests for load_settings() covering basic loading, dotenv,
SecretString, type coercion, and required field validation
- Update all existing tests for new settings patterns
* Fix mypy type errors from settings conversion
- Fix str | None attribute access in responses_client (walrus operator)
- Fix SecretString | None narrowing in bedrock (type: ignore after guard)
- Convert _context_provider.py attribute access to dict access (missed file)
- Fix endpoint type narrowing in search_provider and context_provider
- Fix purview: str | None .rstrip(), int | None defaults, urlparse bytes
* Address PR review: required_fields param, type validation, fixes
- Move required field validation from TypedDict annotations (Required)
to a required_fields parameter on load_settings(), enabling runtime
decisions about which fields are required
- Remove Required imports and restore from __future__ import annotations
in ollama and foundry_local
- Add _check_override_type() for deterministic ServiceInitializationError
on invalid override types (e.g. dict passed for str field)
- Fix all multi-exception test catches back to single exception type
- Fix Ollama host=None: use .get() so None is passed through to SDK default
- Fix Purview processor: use explicit is-None checks instead of or operator
- Remove unused BaseModel import from openai/_shared.py
- Add 4 new tests (24 total): required_fields param, type validation
* Fix type validation: allow int for float fields
_check_override_type now permits int values for float-typed fields,
matching Python's standard numeric promotion behavior.
* fix: wrap urlparse arg with str() to fix mypy bytes endswith error
* Initial plan
* feat: extend AzureOpenAIResponsesClient to support Foundry project endpoints
Add project_client and project_endpoint parameters to allow creating
the client via an Azure AI Foundry project. When provided, the client
uses AIProjectClient.get_openai_client() to obtain the OpenAI client.
The azure-ai-projects package is imported lazily and only required
when using the project endpoint path.

* PR1: Add core context provider types and tests
New types in _sessions.py (no changes to existing code):
- SessionContext: per-invocation state with extend_messages/get_messages/
extend_instructions/extend_tools and read-only response property
- _ContextProviderBase: base class with before_run/after_run hooks
- _HistoryProviderBase: storage base with load/store flags, abstract
get_messages/save_messages, default before_run/after_run
- AgentSession: lightweight session with state dict, to_dict/from_dict
- InMemoryHistoryProvider: built-in provider storing in session.state
35 unit tests covering all classes and configuration flags.
* feat: keyword-only params, stateless InMemoryHistoryProvider, deep serialization
- Make before_run/after_run parameters keyword-only
- InMemoryHistoryProvider stores ChatMessage objects directly (no per-cycle serialization)
- Deep serialization via to_dict/from_dict only at session boundary
- State type registry for automatic deserialization of registered types
- Updated tests for new serialization approach
* feat: add new-pattern provider implementations for external packages
- _RedisContextProvider(BaseContextProvider) - Redis search/vector context
- _RedisHistoryProvider(BaseHistoryProvider) - Redis-backed message storage
- _Mem0ContextProvider(BaseContextProvider) - Mem0 semantic memory
- _AzureAISearchContextProvider(BaseContextProvider) - Azure AI Search (semantic + agentic)
All use temporary _ prefix names for side-by-side coexistence with existing providers.
Will be renamed in PR2 when old ContextProvider/ChatMessageStore are removed.
* test: add tests for new-pattern provider implementations
- 32 tests for _RedisContextProvider and _RedisHistoryProvider
- 29 tests for _Mem0ContextProvider
- 17 tests for _AzureAISearchContextProvider
* fix: address PR review comments and CI failures
- Move module docstring before imports in _sessions.py (review comment)
- Import TYPE_CHECKING unconditionally in Redis _context_provider.py (NameError on Python <3.12)
- Fix Mem0 test_init_auto_creates_client_when_none to patch at class level
* feat: add source attribution to extend_messages
Set attribution marker in additional_properties for each message
added via extend_messages(), matching the tool attribution pattern.
Uses setdefault to preserve any existing attribution.
* refactor: make attribution value a dict with source_id key
* add attribution and use sets for filters
* Add source_type to message attribution and copy messages in extend_messages
- SessionContext.extend_messages now accepts source as str or object with
source_id attribute; when an object is passed, its class name is recorded
as source_type in the attribution dict
- Messages are shallow-copied before attribution is added so callers'
original objects are never mutated
- Filter framework-internal keys (attribution) from A2A wire metadata
to prevent leaking internal state over the wire
* fix: correct mypy type: ignore comment from union-attr to attr-defined
* set attribution to _attribution
* adjusted naming of bools
* Python: Add long-running agents and background responses support
- Add ContinuationToken TypedDict to core types
- Add continuation_token field to ChatResponse, ChatResponseUpdate,
AgentResponse, and AgentResponseUpdate
- Add background and continuation_token options to OpenAIResponsesOptions
- Implement polling via responses.retrieve() and streaming resumption
in RawOpenAIResponsesClient
- Propagate continuation tokens through agent run() and
map_chat_to_agent_update
- Fix streaming telemetry 'Failed to detach context' error in both
ChatTelemetryLayer and AgentTelemetryLayer by avoiding
trace.use_span() context attachment for async-managed spans
- Add 14 unit tests for continuation token types and background flows
- Add background_responses sample showing polling and stream resumption
Fixes#2478
* Python: Add A2A long-running task support via ContinuationToken
- Make ContinuationToken provider-agnostic (total=False, optional task_id/context_id fields)
- Add background param to A2AAgent.run() controlling token emission
- Add poll_task() for single-request task state retrieval
- Add resubscribe support via continuation_token param on run()
- Extract _updates_from_task() and _map_a2a_stream() for cleaner code
- Streamline run()/streaming by removing intermediate _stream_updates wrapper
- Update A2A sample to show background=False (default) with link to background_responses sample
- Remove stale BareAgent from __all__
- Add 12 new A2A continuation token tests
* fix logic for overriding continuation token when done
* refactored ContinuationToken setup
* Update message source code to match python.
* Apply suggestion from @Copilot

RunCoreStreamingAsync was passing inputMessagesForProviders (which lacks
chat history) to GetStreamingResponseAsync instead of
inputMessagesForChatClient (which includes chat history). This caused
streaming runs to lose conversation context on subsequent calls.
The non-streaming path (RunCoreAsync) already correctly used
inputMessagesForChatClient. This aligns the streaming path to match.
Also adds a unit test that validates chat history is included in
messages sent to the chat client during streaming on subsequent calls.

* Python: fix prek runner running fmt/lint in all packages on core change
When a core package file changed, run_tasks_in_changed_packages.py ran
fmt, lint, and pyright in ALL 22 packages (66 tasks). Only type-checking
tasks (pyright, mypy) need to propagate to all packages since type
changes in core affect downstream packages. File-local tasks (fmt, lint)
only need to run in packages with actual file changes.
This reduces a core-only change from 66 tasks to 24 tasks (2 local +
22 pyright).
Also adds no-commit-to-branch builtin hook to protect the main branch
from direct commits.
* Python: add agent skills extracted from AGENTS.md and coding standards
Add 5 skills to python/.github/skills/ following the Agent Skills format:
- python-development: coding standards, type annotations, docstrings, logging
- python-testing: test structure, fixtures, running tests, async mode
- python-code-quality: linting, formatting, type checking, prek hooks, CI
- python-package-management: monorepo structure, lazy loading, versioning
- python-samples: sample structure, PEP 723, documentation guidelines
* Python: deduplicate AGENTS.md and instructions with agent skills
* updated skills
* fixes from review
* Python: increase timeout for web search integration test
* Add ADR for Python ContextMiddleware unification
* Add session serialization/deserialization design to ADR
* Add Related Issues section mapping to ADR
* Update session management: create_session, get_session_by_id, agent.serialize_session
* ADR: Add hooks alternative, context compaction discussion, and PR feedback
- Add Option 3: ContextHooks with before_run/after_run pattern
- Add detailed pros/cons for both wrapper and hooks approaches
- Add Open Discussion section on context compaction strategies
- Clarify response_messages is read-only (use AgentMiddleware for modifications)
- Add SimpleRAG examples showing input-only filtering
- Clarify default storage only added when NO middleware configured
- Add RAGWithBuffer examples for self-managed history
- Rename hook methods to before_run/after_run
* ADR: Restructure and add .NET comparison
- Add class hierarchy clarification for both options
- Merge detailed design sections (side-by-side comparison)
- Move detailed design before decision outcome
- Move compaction discussion after decision
- Add .NET implementation comparison (feature equivalence)
- Update .NET method names to match actual implementation
- Rename hook methods to before_run/after_run
- Fix storage context table for injected context
* tweaks
* fix smart load
* ADR: Add naming discussion note for ContextHooks
- Note that class and method names are open for discussion
- Add alternative method naming options table
- Include invoking/invoked as option matching current Python and .NET
* Update context middleware design: remove smart mode, add attribution filtering
- Remove smart mode for load_messages (now explicit bool, default True)
- Add attribution marker in additional_properties for message filtering
- Update validation to warn on multiple or zero storage loaders
- Add note about ChatReducer naming from .NET
- Note that attribution should not be propagated to storage
* Add Decision 2: Instance Ownership (instances in session vs agent)
- Option A: Instances in Session (current proposal)
- Option B: Instances in Agent, State in Session
- B1: Simple dict state with optional return
- B2: SessionState object with mutable wrapper
- Updated examples to use Hooks pattern (before_run/after_run)
- Added open discussion on hook factories in Option B model
* Update ADR: Choose ContextPlugin with before_run/after_run and Option B1
Decision outcomes:
- Option 3 (Hooks pattern) with ContextPlugin class name
- Methods: before_run/after_run
- Option B1: Instances in Agent, State in Session (simple dict)
- Whole state dict passed to plugins (mutable, no return needed)
- Added trust note: plugins reason over messages, so they're trusted by default
Status changed from proposed to accepted.
* Add agent and session params to before_run/after_run methods
Signature now: before_run(agent, session, context, state)
* Remove ContextPluginRunner, store plugins directly on agent
Simpler design: agent stores Sequence[ContextPlugin] and calls
before_run/after_run directly in the run method.
* Update workplan to 2 PRs for simpler review
* updated doc
* Refine ADR: serialization, ownership, decorators, session methods, exports
- Add to_dict()/from_dict() on AgentSession with 'type' discriminator
- Present serialization as Option A (direct) vs Option B (through agent)
- Rewrite ownership section as 2x2 matrix (orthogonal decision)
- Move Instance Ownership Options before Decision Outcome
- Fix get_session to use service_session_id, split from create_session
- Add decorator-based provider convenience API (@before_run/@after_run)
- Add _ prefix naming strategy for all PR1 types (core + external)
- Constructor compatibility table for existing providers
- Add load_messages=False skip logic to all agent run loops
- Clarify abstract vs non-abstract in execution pattern samples
- Update auto-provision: trigger on conversation_id or store=True
- Document root package exports (ContextProvider, HistoryProvider, etc.)
- Rename section heading to 'Key Design Considerations'
* Rename ADR to 0016-python-context-middleware.md
* Fix broken link: #3-unified-storage-middleware → #3-unified-storage
* feat(workflows): Make telemetry opt-in via WithOpenTelemetry()
- Add WorkflowTelemetryOptions class with EnableSensitiveData property
- Add WorkflowTelemetryContext to manage ActivitySource lifecycle
- Add WithOpenTelemetry() extension method on WorkflowBuilder
- Update all workflow components to use telemetry context:
- WorkflowBuilder, Workflow, Executor
- InProcessRunnerContext, InProcessRunner
- LockstepRunEventStream, StreamingRunEventStream
- All edge runners (Direct, FanIn, FanOut, Response)
- Telemetry is now disabled by default
- Users must call WithOpenTelemetry() to enable spans/activities
BREAKING CHANGE: Workflow telemetry is now opt-in. Users who relied on
automatic telemetry must add .WithOpenTelemetry() to their workflow builder.
* refactor: Pass telemetry context as parameter instead of via interface
- Remove IWorkflowContextWithTelemetry interface
- Add internal ExecuteAsync overload that accepts WorkflowTelemetryContext
- Public ExecuteAsync delegates with WorkflowTelemetryContext.Disabled
- InProcessRunner passes TelemetryContext when calling ExecuteAsync
- BoundContext now implements IWorkflowContext (not the removed interface)
* Add optional ActivitySource parameter to WithOpenTelemetry
Allow users to provide their own ActivitySource when enabling telemetry,
giving them better control over the ActivitySource lifecycle. When not
provided, the framework creates one internally (existing behavior).
Changes:
- Add optional activitySource parameter to WithOpenTelemetry() extension
- Update WorkflowTelemetryContext to accept external ActivitySource
- Add unit test for user-provided ActivitySource scenario
* Add component-level telemetry control with disable flags
Allow users to selectively disable specific activity types via
WorkflowTelemetryOptions. All activities are enabled by default.
New disable flags:
- DisableWorkflowBuild: Disables workflow.build activities
- DisableWorkflowRun: Disables workflow_invoke activities
- DisableExecutorProcess: Disables executor.process activities
- DisableEdgeGroupProcess: Disables edge_group.process activities
- DisableMessageSend: Disables message.send activities
Added helper methods to WorkflowTelemetryContext for each activity type
and updated all activity creation sites to use them.
* Implement EnableSensitiveData to log executor input/output
When EnableSensitiveData is true in WorkflowTelemetryOptions, executor
input and output are logged as JSON-serialized attributes in the
executor.process activity.
New activity tags:
- executor.input: JSON serialized input message
- executor.output: JSON serialized output result (non-void only)
Added suppression attributes for AOT/trimming warnings since this is
an opt-in feature for debugging/diagnostics.
* Refactor activity start methods to centralize tagging logic
Move tagging logic into WorkflowTelemetryContext methods:
- StartExecutorProcessActivity now accepts executorId, executorType,
messageType, and message; sets all tags including executor.input
when EnableSensitiveData is true
- Added SetExecutorOutput method to set executor.output after execution
- StartMessageSendActivity now accepts sourceId, targetId, and message;
sets all tags including message.content when EnableSensitiveData is true
Simplified Executor.cs and InProcessRunnerContext.cs by removing
inline tagging code. Added message.content tag constant.

* python: replace pre-commit with prek, add PEP 723 script deps, clean up dev dependencies
- Replace pre-commit with prek (Rust-native, faster pre-commit alternative)
- Move supported hooks to repo: builtin for zero-clone speed
- Add new builtin hooks: trailing-whitespace, check-merge-conflict, detect-private-key, check-added-large-files
- Update all hook versions to latest (pre-commit-hooks v6, pyupgrade v3.21.2, bandit 1.9.3, uv-pre-commit 0.10.0)
- Add PEP 723 inline script metadata to 34 samples with external deps
- Remove autogen-agentchat/autogen-ext from dev deps (now declared per-sample)
- Remove unused dev deps: pytest-env, tomli-w
- Add agent-framework-core>=1.0.0b260130 lower bound to all 21 packages
- Update CI workflow to use j178/prek-action
- Update docs: DEV_SETUP.md, AGENTS.md, CODING_STANDARD.md, SAMPLE_GUIDELINES.md
* updated lock
* python: fix prek config paths for local execution and CI workflow
Remove global 'files: ^python/' filter and strip python/ prefix from all path patterns in .pre-commit-config.yaml so prek finds files when run from the python/ directory. Update CI workflow to use --cd python instead of --config path. Include trailing whitespace fixes and dev dependency cleanup.
* python: move helper scripts to scripts/ folder and exclude from checks
* python: exclude AGENTS.md from prek markdown code lint
* python: exclude AGENTS.md and azure_ai_search sample from markdown lint
* fix m365 sample
* python: ignore CPY rule for samples with PEP 723 headers
* fix in dev_setup
* python: replace aiofiles with regular open in samples
* python: suppress reportUnusedImport in markdown code block checker
* python: use samples pyright config for markdown code block checker
Write a temp pyrightconfig.json matching pyrightconfig.samples.json rules (typeCheckingMode=off, only reportMissingImports and reportAttributeAccessIssue). Filter output to only fail on these rules since syntax-level errors (top-level await, undefined vars) are expected in README documentation snippets.
* python: use markdown-code-lint with fixed globs instead of prek file list
The prek-markdown-code-lint task received all changed files including non-README markdown and files with pre-existing broken imports. Replace with the standard markdown-code-lint task which uses the correct glob patterns (README.md, packages/**/README.md, samples/**/*.md).
* python: exclude READMEs with pre-existing broken imports from markdown lint
* python: fix broken README code snippets instead of excluding them
- ag-ui: replace TextContent (removed) with content.type == 'text'
- durabletask: fix import path to durabletask.worker.TaskHubGrpcWorker
- orchestrations: use constructor params instead of .participants() method
- observability: mark deprecated code blocks as plain text, filter
reportMissingImports to agent_framework modules only
- remove README excludes from markdown-code-lint task
* add revision to gaia download
* feat(python): parallelize checks across packages
Run (package × task) cross-product in parallel using ThreadPoolExecutor
and subprocesses. Key changes:
- Add scripts/task_runner.py with shared parallel execution engine
- Update run_tasks_in_packages_if_exists.py to accept multiple tasks
- Update run_tasks_in_changed_packages.py with --files flag and parallel support
- Add check-packages poe task (fmt+lint+pyright+mypy in parallel)
- Add prek-markdown-code-lint and prek-samples-check with change detection
- Split CI code quality workflow into parallel prek and mypy jobs
- Update DEV_SETUP.md to document new parallel behavior
Core package changes still trigger checks on all packages.
* feat(ci): split code quality into 4 parallel jobs
Split the single prek job into parallel jobs:
- pre-commit-hooks: lightweight hooks (SKIP=poe-check)
- package-checks: fmt/lint/pyright/mypy via check-packages
- samples-markdown: samples-lint, samples-syntax, markdown-code-lint
- mypy: change-detected mypy checks
All 4 jobs run concurrently (×2 Python versions = 8 runners).
* feat(ci): use only Python 3.10 for code quality checks
* refactor(python): add future annotations and remove quoted types
Add `from __future__ import annotations` to 93 package files that
used quoted string annotations, then run pyupgrade --py310-plus to
remove the now-unnecessary quotes.

- FunctionInvocationLayer (second)
- ChatTelemetryLayer (third)

* fix: call get_final_response() to trigger context provider notification in streaming test
* fix: correct broken links in tools README
* docs: clarify default middleware behavior in summary table
* fix: ensure inner stream result hooks are called when using map()/from_awaitable()
* Fix mypy type errors
* Address PR review comments on observability.py
- Remove TODO comment about unconsumed streams, add explanatory note instead
- Remove redundant _close_span cleanup hook (already called in _finalize_stream)
- Clarify behavior: cleanup hooks run after stream iteration, if stream is not
consumed the span remains open until garbage collected
* Remove gen_ai.client.operation.duration from span attributes
Duration is a metrics-only attribute per OpenTelemetry semantic conventions.
It should be recorded to the histogram but not set as a span attribute.
* Remove duration from _get_response_attributes, pass directly to _capture_response
Duration is a metrics-only attribute. It's now passed directly to _capture_response
instead of being included in the attributes dict that gets set on the span.
* Remove redundant _close_span cleanup hook in AgentTelemetryLayer
_finalize_stream already calls _close_span() in its finally block,
so adding it as a separate cleanup hook is redundant.
* Use weakref.finalize to close span when stream is garbage collected
If a user creates a streaming response but never consumes it, the cleanup
hooks won't run. Now we register a weak reference finalizer that will close
the span when the stream object is garbage collected, ensuring spans don't
leak in this scenario.
* Fix _get_finalizers_from_stream to use _result_hooks attribute
Renamed function to _get_result_hooks_from_stream and fixed it to
look for the _result_hooks attribute which is the correct name in
ResponseStream class.
* Add missing asyncio import in test_request_info_mixin.py
* Fix leftover merge conflict marker in image_generation sample
* Update integration tests
* Fix integration tests: increase max_iterations from 1 to 2
Tests with tool_choice options require at least 2 iterations:
1. First iteration to get function call and execute the tool
2. Second iteration to get the final text response
With max_iterations=1, streaming tests would return early with only
the function call/result but no final text content.
* Fix duplicate function call error in conversation-based APIs
When using conversation_id (for Responses/Assistants APIs), the server
already has the function call message from the previous response. We
should only send the new function result message, not all messages
including the function call which would cause a duplicate ID error.
Fix: When conversation_id is set, only send the last message (the tool
result) instead of all response.messages.
* Add regression test for conversation_id propagation between tool iterations
Port test from PR #3664 with updates for new streaming API pattern.
Tests that conversation_id is properly updated in options dict during
function invocation loop iterations.
* Fix tool_choice=required to return after tool execution
When tool_choice is 'required', the user's intent is to force exactly one
tool call. After the tool executes, return immediately with the function
call and result - don't continue to call the model again.
This fixes integration tests that were failing with empty text responses
because with tool_choice=required, the model would keep returning function
calls instead of text.
Also adds regression tests for:
- conversation_id propagation between tool iterations (from PR #3664)
- tool_choice=required returns after tool execution
* Document tool_choice behavior in tools README
- Add table explaining tool_choice values (auto, none, required)
- Explain why tool_choice=required returns immediately after tool execution
- Add code example showing the difference between required and auto
- Update flow diagram to show the early return path for tool_choice=required
* Fix tool_choice=None behavior - don't default to 'auto'
Remove the hardcoded default of 'auto' for tool_choice in ChatAgent init.
When tool_choice is not specified (None), it will now not be sent to the
API, allowing the API's default behavior to be used.
Users who want tool_choice='auto' can still explicitly set it either in
default_options or at runtime.
Fixes#3585
* Fix tool_choice=none should not remove tools
In OpenAI Assistants client, tools were not being sent when
tool_choice='none'. This was incorrect - tool_choice='none' means
the model won't call tools, but tools should still be available
in the request (they may be used later in the conversation).
Fixes#3585
* Add test for tool_choice=none preserving tools
Adds a regression test to ensure that when tool_choice='none' is set but
tools are provided, the tools are still sent to the API. This verifies
the fix for #3585.
* Fix tool_choice=none should not remove tools in all clients
Apply the same fix to OpenAI Responses client and Azure AI client:
- OpenAI Responses: Remove else block that popped tool_choice/parallel_tool_calls
- Azure AI: Remove tool_choice != 'none' check when adding tools
When tool_choice='none', the model won't call tools, but tools should
still be sent to the API so they're available for future turns.
Also update README to clarify tool_choice=required supports multiple tools.
Fixes#3585
* Keep tool_choice even when tools is None
Move tool_choice processing outside of the 'if tools' block in OpenAI
Responses client so tool_choice is sent to the API even when no tools
are provided.
* Update test to match new parallel_tool_calls behavior
Changed test_prepare_options_removes_parallel_tool_calls_when_no_tools to
test_prepare_options_preserves_parallel_tool_calls_when_no_tools to reflect
that parallel_tool_calls is now preserved even when no tools are present,
consistent with the tool_choice behavior.

- Update ChatMessage instantiation to use keyword args (role=, text=, contents=)
- Fix Role enum comparisons to use .value for string comparison
- Add created_at to AgentResponse in error handling
- Fix AgentResponse.from_updates -> from_agent_run_response_updates
- Fix DurableAgentStateMessage.from_chat_message to convert Role enum to string

* Remove duplicate test files from ag-ui/tests (tests are in ag_ui_tests)
* Fix ChatMessage and Role API changes across packages
After rebasing on upstream/main which merged PR #3647 (Types API Review
improvements), fix all packages to use the new API:
- ChatMessage: Use keyword args (role=, text=, contents=) instead of
positional args
- Role: Compare using .value attribute since it's now an enum
Packages fixed:
- ag-ui: Fixed Role value extraction bugs in _message_adapters.py
- anthropic: Fixed ChatMessage and Role comparisons in tests

- core: Fix ChatMessage in _orchestrator_helpers.py to use keyword args
- core: Add type ignore for _conversation_state.py contents deserialization
- ag-ui: Fix type ignore comments (call-overload instead of arg-type)
- azure-ai-search: Fix get_role_value type hint to accept Any
- lab: Move get_role_value to module level with Any type hint
* Improve CI test timeout configuration
- Increase job timeout from 10 to 15 minutes
- Reduce per-test timeout to 60s (was 900s/300s)
- Add --timeout_method thread for better timeout handling
- Add --timeout-verbose to see which tests are slow
- Reduce retries from 3 to 2 and delay from 10s to 5s
This ensures individual test timeouts are shorter than the job
timeout, providing better visibility when tests hang.
With 60s timeout and 2 retries, worst case per test is ~180s.
* Fix ChatMessage API usage in docstrings and source
- Fix ChatMessage positional args in docstrings: _serialization.py, _threads.py, _middleware.py
- Fix ChatMessage in tau2 runner.py
- Fix role comparison in _orchestrator_helpers.py to use .value
- Fix role comparison in _group_chat.py docstring example
- Fix role assertions in test_durable_entities.py to use .value
* Revert tool_choice/parallel_tool_calls changes - must be removed when no tools
OpenAI API requires tool_choice and parallel_tool_calls to only be
present when tools are specified. Restored the logic that removes
these options when there are no tools.
- Restored check in _chat_client.py to remove tool_choice and
parallel_tool_calls when no tools present
- Restored same logic in _responses_client.py
- Reverted test to expect the correct behavior
* fixed issue in tests
* fix: resolve merge conflict markers in ag-ui tests
* fix: restructure ag-ui tests and fix Role/FinishReason to use string types
* fix: streaming function invocation and middleware termination
- Refactor streaming function invocation to use get_final_response() on inner streams

- Merge dt_testutils.py into conftest.py for durabletask integration tests
- Convert all integration tests to use fixtures instead of direct imports
(fixes ModuleNotFoundError with --import-mode=importlib)
- Add sample_helper fixture for azurefunctions tests
- Add agent_client_factory and orchestration_helper fixtures for durabletask
- Integration tests now skip with descriptive messages when services unavailable
- Restructure devui tests into tests/devui/ with proper conftest.py
- Add test organization guidelines to CODING_STANDARD.md
- Remove __init__.py from test directories per pytest best practices
* Fix pytest_collection_modifyitems to only skip integration tests
The hook was skipping all tests in the test session, not just
integration tests. Now it only skips items in the integration_tests
directory.
* Fix mem0 tests failing on Python 3.13
Use patch.object on the imported module instead of @patch with string
path to ensure the mock takes effect regardless of import timing.
* fix mem0
* another attempt for mem0
* fix for mem0
* fix mem0
* Increase worker initialization wait time in durabletask tests
Increase from 2 to 8 seconds to allow time for:
- Python startup and module imports
- Azure OpenAI client creation
- Agent registration with DTS worker
- Worker connection to DTS
This helps prevent test failures in CI where the first tests may run
before the worker is fully ready to process requests.
* Fix streaming test to use ResponseStream with finalizer
The _consume_stream method now expects a ResponseStream that can provide
a final AgentResponse via get_final_response(). Update the test to use
ResponseStream with AgentResponse.from_updates as the finalizer.
* Fix MockToolCallingAgent to use new ResponseStream API and update samples
* small updates to run_stream to run
* fix sub workflow
* temp fix for az func test

* Python: Use agent description in HandoffBuilder auto-generated tools (#2713) (#2714)
## Summary
Enhanced `HandoffBuilder._apply_auto_tools` to use the target agent's
description when creating handoff tools, providing more informative tool
descriptions for LLMs.
## Changes
- Modified `_apply_auto_tools` to extract `description` from
`AgentExecutor._agent` when available
- Updated iteration to use `.items()` for more efficient dict traversal
- Handoff tools now use agent descriptions instead of generic placeholders
## Example
Before: "Handoff to the refund_agent agent."
After: "You handle refund requests. Ask for order details and process refunds."
## Testing
- All handoff tests pass (20/20)
- No breaking changes to existing API

* Python: Use agent description in HandoffBuilder auto-generated tools (#2713) (#2714)
## Summary
Enhanced `HandoffBuilder._apply_auto_tools` to use the target agent's
description when creating handoff tools, providing more informative tool
descriptions for LLMs.
## Changes
- Modified `_apply_auto_tools` to extract `description` from
`AgentExecutor._agent` when available
- Updated iteration to use `.items()` for more efficient dict traversal
- Handoff tools now use agent descriptions instead of generic placeholders
## Example
Before: "Handoff to the refund_agent agent."
After: "You handle refund requests. Ask for order details and process refunds."
## Testing
- All handoff tests pass (20/20)
- No breaking changes to existing API
Fixes#2713

* fix: tool_choice parameter not being honored when passed to agent.run() (#3095)

* Python: Fix MCP tool result serialization for list[TextContent] (#2523)
* Fix MCP tool result serialization for list[TextContent]
When MCP tools return results containing list[TextContent], they were
incorrectly serialized to object repr strings like:
'[<agent_framework._types.TextContent object at 0x...>]'
This fix properly extracts text content from list items by:
1. Checking if items have a 'text' attribute (TextContent)
2. Using model_dump() for items that support it
3. Falling back to str() for other types
4. Joining single items as plain text, multiple items as JSON array
Fixes#2509
* Address PR review feedback for MCP tool result serialization
- Extract serialize_content_result() to shared _utils.py
- Fix logic: use texts[0] instead of join for single item
- Add type annotation: texts: list[str] = []
- Return empty string for empty list instead of '[]'
- Move import json to file top level
- Add comprehensive unit tests for serialization
* Address PR review feedback: fix type checking and double serialization
- Add isinstance(item.text, str) check to ensure text attribute is a string
- Fix double-serialization issue by keeping model_dump results as dicts
until final json.dumps (removes escaped JSON strings in arrays)
- Improve docstring with detailed return value documentation
- Add test for non-string text attribute handling
- Add tests for list type tool results in _events.py path
* Simplify PR: minimal changes to fix MCP tool result serialization
Addresses reviewer feedback about excessive refactoring:
- Reset _events.py to original structure
- Only add import and use serialize_content_result in one location
- All review comments addressed in serialize_content_result():
- Added isinstance(item.text, str) check
- Use model_dump(mode="json") to avoid double-serialization
- Improved docstring with explicit return value documentation
- Empty list returns "" instead of "[]"
* Refactor: Move MCP TextContent serialization to core prepare_function_call_results
Per reviewer feedback, moved the TextContent serialization logic from
ag-ui's serialize_content_result to the core package's
prepare_function_call_results function.
Changes:
- Added handling for objects with 'text' attribute (like MCP TextContent)
in _prepare_function_call_results_as_dumpable
- Removed serialize_content_result from ag-ui/_utils.py
- Updated _events.py and _message_adapters.py to use
prepare_function_call_results from core package
- Updated tests to match the core function's behavior
* Fix failing tests for prepare_function_call_results behavior
- test_tool_result_with_none: Update expected value to 'null' (JSON serialization of None)
- test_tool_result_with_model_dump_objects: Use Pydantic BaseModel instead of plain class
* Fix B903 linter error: Convert MockTextContent to dataclass
The ruff linter was reporting B903 (class could be dataclass or namedtuple)
for the MockTextContent test helper classes. This commit converts them to
dataclasses to satisfy the linter check.

* Improve DevUI, add Context Inspector view as new tab under traces
* fix mypy errors
* fix: Handle stale MCP connections in DevUI executor
MCP tools can become stale when HTTP streaming responses end - the underlying
stdio streams close but `is_connected` remains True. This causes subsequent
requests to fail with `ClosedResourceError`.
Add `_ensure_mcp_connections()` to detect and reconnect stale MCP tools before
agent execution. This is a workaround for an upstream Agent Framework issue
where connection state isn't properly tracked.
Fixes MCP tools failing on second HTTP request in DevUI.

* Python: Use agent description in HandoffBuilder auto-generated tools (#2713) (#2714)
## Summary
Enhanced `HandoffBuilder._apply_auto_tools` to use the target agent's
description when creating handoff tools, providing more informative tool
descriptions for LLMs.
## Changes
- Modified `_apply_auto_tools` to extract `description` from
`AgentExecutor._agent` when available
- Updated iteration to use `.items()` for more efficient dict traversal
- Handoff tools now use agent descriptions instead of generic placeholders
## Example
Before: "Handoff to the refund_agent agent."
After: "You handle refund requests. Ask for order details and process refunds."
## Testing
- All handoff tests pass (20/20)
- No breaking changes to existing API
Fixes#2713

* fix: tool_choice parameter not being honored when passed to agent.run() (#3095)

* Bump Bedrock version to latest (#3110)
* Python: Fix MCP tool result serialization for list[TextContent] (#2523)
* Fix MCP tool result serialization for list[TextContent]
When MCP tools return results containing list[TextContent], they were
incorrectly serialized to object repr strings like:
'[<agent_framework._types.TextContent object at 0x...>]'
This fix properly extracts text content from list items by:
1. Checking if items have a 'text' attribute (TextContent)
2. Using model_dump() for items that support it
3. Falling back to str() for other types
4. Joining single items as plain text, multiple items as JSON array
Fixes#2509
* Address PR review feedback for MCP tool result serialization
- Extract serialize_content_result() to shared _utils.py
- Fix logic: use texts[0] instead of join for single item
- Add type annotation: texts: list[str] = []
- Return empty string for empty list instead of '[]'
- Move import json to file top level
- Add comprehensive unit tests for serialization
* Address PR review feedback: fix type checking and double serialization
- Add isinstance(item.text, str) check to ensure text attribute is a string
- Fix double-serialization issue by keeping model_dump results as dicts
until final json.dumps (removes escaped JSON strings in arrays)
- Improve docstring with detailed return value documentation
- Add test for non-string text attribute handling
- Add tests for list type tool results in _events.py path
* Simplify PR: minimal changes to fix MCP tool result serialization
Addresses reviewer feedback about excessive refactoring:
- Reset _events.py to original structure
- Only add import and use serialize_content_result in one location
- All review comments addressed in serialize_content_result():
- Added isinstance(item.text, str) check
- Use model_dump(mode="json") to avoid double-serialization
- Improved docstring with explicit return value documentation
- Empty list returns "" instead of "[]"
* Refactor: Move MCP TextContent serialization to core prepare_function_call_results
Per reviewer feedback, moved the TextContent serialization logic from
ag-ui's serialize_content_result to the core package's
prepare_function_call_results function.
Changes:
- Added handling for objects with 'text' attribute (like MCP TextContent)
in _prepare_function_call_results_as_dumpable
- Removed serialize_content_result from ag-ui/_utils.py
- Updated _events.py and _message_adapters.py to use
prepare_function_call_results from core package
- Updated tests to match the core function's behavior
* Fix failing tests for prepare_function_call_results behavior
- test_tool_result_with_none: Update expected value to 'null' (JSON serialization of None)
- test_tool_result_with_model_dump_objects: Use Pydantic BaseModel instead of plain class
* Fix B903 linter error: Convert MockTextContent to dataclass
The ruff linter was reporting B903 (class could be dataclass or namedtuple)
for the MockTextContent test helper classes. This commit converts them to
dataclasses to satisfy the linter check.
* Python: Improve DevUI, add Context Inspector view as new tab under traces (#2742)
* Improve DevUI, add Context Inspector view as new tab under traces
* fix mypy errors
* fix: Handle stale MCP connections in DevUI executor
MCP tools can become stale when HTTP streaming responses end - the underlying
stdio streams close but `is_connected` remains True. This causes subsequent
requests to fail with `ClosedResourceError`.
Add `_ensure_mcp_connections()` to detect and reconnect stale MCP tools before
agent execution. This is a workaround for an upstream Agent Framework issue
where connection state isn't properly tracked.
Fixes MCP tools failing on second HTTP request in DevUI.

* fix(anthropic): fix duplicate ToolCallStartEvent in streaming tool calls (#3051)
When processing `input_json_delta` events, the Anthropic client was
passing the tool name from the previous `tool_use` event. This caused
ag-ui's `_handle_function_call_content` to emit a `ToolCallStartEvent`
for every streaming chunk (since it triggers on `if content.name:`).
This fix changes the behavior to pass an empty string for `name` in
`input_json_delta` events, matching OpenAI's behavior where streaming
argument chunks have `name=""`. The initial `tool_use` event still
provides the tool name, so only one `ToolCallStartEvent` is emitted.

* Python: Add Pydantic request model and OpenAPI tags support to AG-UI FastAPI endpoint (#2522)
* feat(ag-ui): Add Pydantic request model and OpenAPI tags support
- Add AGUIRequest Pydantic model in _types.py with field descriptions
- Update add_agent_framework_fastapi_endpoint() to accept tags parameter
- Use AGUIRequest model for automatic validation and OpenAPI schema generation
- Export AGUIRequest and DEFAULT_TAGS in __init__.py

- Add tests for OpenAPI schema, default tags, custom tags, and validation
Benefits:
- Better API documentation with complete request schema in Swagger UI
- Automatic request validation with Pydantic
- Organized endpoints under 'AG-UI' tag instead of 'default'
- Improved developer experience and type safety
Fixes #<issue-number>

* Python: Use agent description in HandoffBuilder auto-generated tools (#2713) (#2714)
## Summary
Enhanced `HandoffBuilder._apply_auto_tools` to use the target agent's
description when creating handoff tools, providing more informative tool
descriptions for LLMs.
## Changes
- Modified `_apply_auto_tools` to extract `description` from
`AgentExecutor._agent` when available
- Updated iteration to use `.items()` for more efficient dict traversal
- Handoff tools now use agent descriptions instead of generic placeholders
## Example
Before: "Handoff to the refund_agent agent."
After: "You handle refund requests. Ask for order details and process refunds."
## Testing
- All handoff tests pass (20/20)
- No breaking changes to existing API
Fixes#2713

'[<agent_framework._types.TextContent object at 0x...>]'
This fix properly extracts text content from list items by:
1. Checking if items have a 'text' attribute (TextContent)
2. Using model_dump() for items that support it
3. Falling back to str() for other types
4. Joining single items as plain text, multiple items as JSON array
Fixes#2509
* Address PR review feedback for MCP tool result serialization
- Extract serialize_content_result() to shared _utils.py
- Fix logic: use texts[0] instead of join for single item
- Add type annotation: texts: list[str] = []
- Return empty string for empty list instead of '[]'
- Move import json to file top level
- Add comprehensive unit tests for serialization
* Address PR review feedback: fix type checking and double serialization
- Add isinstance(item.text, str) check to ensure text attribute is a string
- Fix double-serialization issue by keeping model_dump results as dicts
until final json.dumps (removes escaped JSON strings in arrays)
- Improve docstring with detailed return value documentation
- Add test for non-string text attribute handling
- Add tests for list type tool results in _events.py path
* Simplify PR: minimal changes to fix MCP tool result serialization
Addresses reviewer feedback about excessive refactoring:
- Reset _events.py to original structure
- Only add import and use serialize_content_result in one location
- All review comments addressed in serialize_content_result():
- Added isinstance(item.text, str) check
- Use model_dump(mode="json") to avoid double-serialization
- Improved docstring with explicit return value documentation
- Empty list returns "" instead of "[]"
* Refactor: Move MCP TextContent serialization to core prepare_function_call_results
Per reviewer feedback, moved the TextContent serialization logic from
ag-ui's serialize_content_result to the core package's
prepare_function_call_results function.
Changes:
- Added handling for objects with 'text' attribute (like MCP TextContent)
in _prepare_function_call_results_as_dumpable
- Removed serialize_content_result from ag-ui/_utils.py
- Updated _events.py and _message_adapters.py to use
prepare_function_call_results from core package
- Updated tests to match the core function's behavior
* Fix failing tests for prepare_function_call_results behavior
- test_tool_result_with_none: Update expected value to 'null' (JSON serialization of None)
- test_tool_result_with_model_dump_objects: Use Pydantic BaseModel instead of plain class
* Fix B903 linter error: Convert MockTextContent to dataclass
The ruff linter was reporting B903 (class could be dataclass or namedtuple)
for the MockTextContent test helper classes. This commit converts them to
dataclasses to satisfy the linter check.

* Improve DevUI, add Context Inspector view as new tab under traces
* fix mypy errors
* fix: Handle stale MCP connections in DevUI executor
MCP tools can become stale when HTTP streaming responses end - the underlying
stdio streams close but `is_connected` remains True. This causes subsequent
requests to fail with `ClosedResourceError`.
Add `_ensure_mcp_connections()` to detect and reconnect stale MCP tools before
agent execution. This is a workaround for an upstream Agent Framework issue
where connection state isn't properly tracked.
Fixes MCP tools failing on second HTTP request in DevUI.

* fix(anthropic): fix duplicate ToolCallStartEvent in streaming tool calls (#3051)
When processing `input_json_delta` events, the Anthropic client was
passing the tool name from the previous `tool_use` event. This caused
ag-ui's `_handle_function_call_content` to emit a `ToolCallStartEvent`
for every streaming chunk (since it triggers on `if content.name:`).
This fix changes the behavior to pass an empty string for `name` in
`input_json_delta` events, matching OpenAI's behavior where streaming
argument chunks have `name=""`. The initial `tool_use` event still
provides the tool name, so only one `ToolCallStartEvent` is emitted.

* Python: Fix: Add system_instructions to ChatClient LLM span tracing (#3164)
* Fix: Add system_instructions to ChatClient LLM span tracing
- Add system_instructions parameter to _capture_messages() calls in
_trace_get_response() and _trace_get_streaming_response()
- Extract instructions from chat_options in kwargs
- Add unit tests to verify system_instructions are captured correctly
When using ChatClient with ChatOptions.instructions, the OpenTelemetry
LLM span was missing system messages in gen_ai.input.messages and the
gen_ai.system_instructions attribute was not being set.
This fix aligns the ChatClient-level tracing with the Agent-level
tracing which already correctly passes system_instructions.

Subworkflows run into issues with Checkpointing and the Chat Protocol:
* The concurrency rework made subtle changes in behaviour that introduced a hang when using subworkflows with ChatProtocol and streaming execution.
* The ResetAsync() implementation in WorkflowHostExecutor was improperly resetting the joinContext - this was happening on restore checkpoint _after_ the join context was attached when
* Subworkflows cannot be used as the start node when hosted AsAgent due to inability to treat Catch-All as a Chat Protocol
* Subworkflow ownership issue when used in non-concurrent mode after finishing a run
Also fixes:
* When ChatMessages are output by executors that are not agents, there is no corresponding AgentResponseUpdate/AgentResponse event

* feat(ag-ui): Add Pydantic request model and OpenAPI tags support

- Export AGUIRequest and DEFAULT_TAGS in __init__.py
- Update test_endpoint.py to expect 422 for invalid requests
- Add tests for OpenAPI schema, default tags, custom tags, and validation
Benefits:
- Better API documentation with complete request schema in Swagger UI
- Automatic request validation with Pydantic
- Organized endpoints under 'AG-UI' tag instead of 'default'
- Improved developer experience and type safety
Fixes #<issue-number>
* test(ag-ui): Add test for internal error handling to achieve 100% coverage
- Add test_endpoint_internal_error_handling() to cover exception handling code
- Mock copy.deepcopy to simulate internal error during default_state processing
- Add type: ignore for FastAPI tags parameter (known pyright compatibility issue)
- Achieves 100% test coverage for _endpoint.py (previously missing lines 103-105)
When processing `input_json_delta` events, the Anthropic client was
passing the tool name from the previous `tool_use` event. This caused
ag-ui's `_handle_function_call_content` to emit a `ToolCallStartEvent`
for every streaming chunk (since it triggers on `if content.name:`).
This fix changes the behavior to pass an empty string for `name` in
`input_json_delta` events, matching OpenAI's behavior where streaming
argument chunks have `name=""`. The initial `tool_use` event still
provides the tool name, so only one `ToolCallStartEvent` is emitted.

* Improve DevUI, add Context Inspector view as new tab under traces
* fix mypy errors
* fix: Handle stale MCP connections in DevUI executor
MCP tools can become stale when HTTP streaming responses end - the underlying
stdio streams close but `is_connected` remains True. This causes subsequent
requests to fail with `ClosedResourceError`.
Add `_ensure_mcp_connections()` to detect and reconnect stale MCP tools before
agent execution. This is a workaround for an upstream Agent Framework issue
where connection state isn't properly tracked.
Fixes MCP tools failing on second HTTP request in DevUI.
fixes #1476#1515#2865
* fix#1572 report import dependency errors more clearly
* Ensure there is streaming toggle where users can select streaming vs non streaming mode in devui . Fixes .NET: [Python] DevUI tool call rendering in non-streaming mode?
* remove unused dead code

* update ui build

* Fix MCP tool result serialization for list[TextContent]
When MCP tools return results containing list[TextContent], they were
incorrectly serialized to object repr strings like:
'[<agent_framework._types.TextContent object at 0x...>]'
This fix properly extracts text content from list items by:
1. Checking if items have a 'text' attribute (TextContent)
2. Using model_dump() for items that support it
3. Falling back to str() for other types
4. Joining single items as plain text, multiple items as JSON array
Fixes#2509
* Address PR review feedback for MCP tool result serialization
- Extract serialize_content_result() to shared _utils.py
- Fix logic: use texts[0] instead of join for single item
- Add type annotation: texts: list[str] = []
- Return empty string for empty list instead of '[]'
- Move import json to file top level
- Add comprehensive unit tests for serialization
* Address PR review feedback: fix type checking and double serialization
- Add isinstance(item.text, str) check to ensure text attribute is a string
- Fix double-serialization issue by keeping model_dump results as dicts
until final json.dumps (removes escaped JSON strings in arrays)
- Improve docstring with detailed return value documentation
- Add test for non-string text attribute handling
- Add tests for list type tool results in _events.py path
* Simplify PR: minimal changes to fix MCP tool result serialization
Addresses reviewer feedback about excessive refactoring:
- Reset _events.py to original structure
- Only add import and use serialize_content_result in one location
- All review comments addressed in serialize_content_result():
- Added isinstance(item.text, str) check
- Use model_dump(mode="json") to avoid double-serialization
- Improved docstring with explicit return value documentation
- Empty list returns "" instead of "[]"
* Refactor: Move MCP TextContent serialization to core prepare_function_call_results
Per reviewer feedback, moved the TextContent serialization logic from
ag-ui's serialize_content_result to the core package's
prepare_function_call_results function.
Changes:
- Added handling for objects with 'text' attribute (like MCP TextContent)
in _prepare_function_call_results_as_dumpable
- Removed serialize_content_result from ag-ui/_utils.py
- Updated _events.py and _message_adapters.py to use
prepare_function_call_results from core package
- Updated tests to match the core function's behavior
* Fix failing tests for prepare_function_call_results behavior
- test_tool_result_with_none: Update expected value to 'null' (JSON serialization of None)
- test_tool_result_with_model_dump_objects: Use Pydantic BaseModel instead of plain class
* Fix B903 linter error: Convert MockTextContent to dataclass
The ruff linter was reporting B903 (class could be dataclass or namedtuple)
for the MockTextContent test helper classes. This commit converts them to
dataclasses to satisfy the linter check.

## Summary
Enhanced `HandoffBuilder._apply_auto_tools` to use the target agent's
description when creating handoff tools, providing more informative tool
descriptions for LLMs.
## Changes
- Modified `_apply_auto_tools` to extract `description` from
`AgentExecutor._agent` when available
- Updated iteration to use `.items()` for more efficient dict traversal
- Handoff tools now use agent descriptions instead of generic placeholders
## Example
Before: "Handoff to the refund_agent agent."
After: "You handle refund requests. Ask for order details and process refunds."
## Testing
- All handoff tests pass (20/20)
- No breaking changes to existing API

All python code resides under the `python/` directory.
All C# code resides under the `dotnet/` directory.
Microsoft Agent Framework - a multi-language framework for building, orchestrating, and deploying AI agents.
The purpose of the code is to provide a framework for building AI agents.
## Repository Structure
When contributing to this repository, please follow these guidelines:
-`python/` - Python implementation → see [python/AGENTS.md](../python/AGENTS.md)
-`dotnet/` - C#/.NET implementation → see [dotnet/AGENTS.md](../dotnet/AGENTS.md)
-`docs/` - Design documents and architectural decision records
## C# Code Guidelines
## Architectural Decision Records (ADRs)
Here are some general guidelines that apply to all code.
ADRs in `docs/decisions/` capture significant design decisions and their rationale. They document considered alternatives, trade-offs, and the reasoning behind choices.
- The top of all *.cs files should have a copyright notice: `// Copyright (c) Microsoft. All rights reserved.`
-All public methods and classes should have XML documentation comments.
**Templates:**
-`adr-template.md` - Full template with detailed sections
-`adr-short-template.md` - Abbreviated template for simpler decisions
### C# Sample Code Guidelines
Sample code is located in the `dotnet/samples` directory.
When adding a new sample, follow these steps:
- The sample should be a standalone .net project in one of the subdirectories of the samples directory.
- The directory name should be the same as the project name.
- The directory should contain a README.md file that explains what the sample does and how to run it.
- The README.md file should follow the same format as other samples.
- The csproj file should match the directory name.
- The csproj file should be configured in the same way as other samples.
- The project should preferably contain a single Program.cs file that contains all the sample code.
- The sample should be added to the solution file in the samples directory.
- The sample should be tested to ensure it works as expected.
- A reference to the new samples should be added to the README.md file in the parent directory of the new sample.
The sample code should follow these guidelines:
- Configuration settings should be read from environment variables, e.g. `var endpoint = Environment.GetEnvironmentVariable("AZURE_OPENAI_ENDPOINT") ?? throw new InvalidOperationException("AZURE_OPENAI_ENDPOINT is not set.");`.
- Environment variables should use upper snake_case naming convention.
- Secrets should not be hardcoded in the code or committed to the repository.
- The code should be well-documented with comments explaining the purpose of each step.
- The code should be simple and to the point, avoiding unnecessary complexity.
- Prefer inline literals over constants for values that are not reused. For example, use `new ChatClientAgent(chatClient, instructions: "You are a helpful assistant.")` instead of defining a constant for "instructions".
- Ensure that all private classes are sealed
- Use the Async suffix on the name of all async methods that return a Task or ValueTask.
- Prefer defining variables using types rather than var, to help users understand the types involved.
- Follow the patterns in the samples in the same directories where new samples are being added.
- The structure of the sample should be as follows:
- The top of the Program.cs should have a copyright notice: `// Copyright (c) Microsoft. All rights reserved.`
- Then add a comment describing what the sample is demonstrating.
- Then add the necessary using statements.
- Then add the main code logic.
- Finally, add any helper methods or classes at the bottom of the file.
### C# Unit Test Guidelines
Unit tests are located in the `dotnet/tests` directory in projects with a `.UnitTests.csproj` suffix.
Unit tests should follow these guidelines:
- Use `this.` for accessing class members
- Add Arrange, Act and Assert comments for each test
- Ensure that all private classes, that are not subclassed, are sealed
- Use the Async suffix on the name of all async methods
- Use the Moq library for mocking objects where possible
- Validate that each test actually tests the target behavior, e.g. we should not have tests that creates a mock, calls the mock and then verifies that the mock was called, without the target code being involved. We also shouldn't have tests that test language features, e.g. something that the compiler would catch anyway.
- Avoid adding excessive comments to tests. Instead favour clear easy to understand code.
- Follow the patterns in the unit tests in the same project or classes to which new tests are being added
When proposing architectural changes, create an ADR to capture options considered and the decision rationale. See [docs/decisions/README.md](../docs/decisions/README.md) for the full process.

Welcome to Microsoft's comprehensive multi-language framework for building, orchestrating, and deploying AI agents with support for both .NET and Python implementations. This framework provides everything from simple chat agents to complex multi-agent workflows with graph-based orchestration.
Microsoft Agent Framework (MAF) is an open, multi-language framework for building **production-grade AI agents and multi-agent workflows** in **.NET and Python**.
Microsoft Agent Framework is built for teams taking agents from prototype to production. It provides a consistent foundation for building, orchestrating, and operating agent systems across Python and .NET, while keeping architecture choices open as requirements evolve, and supports a broad ecosystem including Microsoft Foundry, Azure OpenAI, OpenAI, and the GitHub Copilot SDK, with samples and hosting patterns for both local development and cloud deployment.

There is a misalignment between the create/get agent API in the .NET and Python implementations.
In .NET, the `CreateAIAgent` method can create either a local instance of an agent or a remote instance if the backend provider supports it. For remote agents, once the agent is created, you can retrieve an existing remote agent by using the `GetAIAgent` method. If a backend provider doesn't support remote agents, `CreateAIAgent` just initializes a new local agent instance and `GetAIAgent` is not available. There is also a `BuildAIAgent` method, which is an extension for the `ChatClientBuilder` class from `Microsoft.Extensions.AI`. It builds pipelines of `IChatClient` instances with an `IServiceProvider`. This functionality does not exist in Python, so `BuildAIAgent` is out of scope.
In Python, there is only one `create_agent` method, which always creates a local instance of the agent. If the backend provider supports remote agents, the remote agent is created only on the first `agent.run()` invocation.
Below is a short summary of different providers and their APIs in .NET:
| Package | Method | Behavior | Python support |
|---|---|---|---|
| Microsoft.Agents.AI | `CreateAIAgent` (based on `IChatClient`) | Creates a local instance of `ChatClientAgent`. | Yes (`create_agent` in `BaseChatClient`). |
| Microsoft.Agents.AI.Anthropic | `CreateAIAgent` (based on `IBetaService` and `IAnthropicClient`) | Creates a local instance of `ChatClientAgent`. | Yes (`AnthropicClient` inherits `BaseChatClient`, which exposes `create_agent`). |
| Microsoft.Agents.AI.AzureAI (V2) | `GetAIAgent` (based on `AIProjectClient` with `AgentReference`) | Creates a local instance of `ChatClientAgent`. | Partial (Python uses `create_agent` from `BaseChatClient`). |
| Microsoft.Agents.AI.AzureAI (V2) | `GetAIAgent`/`GetAIAgentAsync` (with `Name`/`ChatClientAgentOptions`) | Fetches `AgentRecord` via HTTP, then creates a local `ChatClientAgent` instance. | No |
| Microsoft.Agents.AI.AzureAI (V2) | `CreateAIAgent`/`CreateAIAgentAsync` (based on `AIProjectClient`) | Creates a remote agent first, then wraps it into a local `ChatClientAgent` instance. | No |
| Microsoft.Agents.AI.AzureAI.Persistent (V1) | `GetAIAgent` (based on `PersistentAgentsClient` with `PersistentAgent`) | Creates a local instance of `ChatClientAgent`. | Partial (Python uses `create_agent` from `BaseChatClient`). |
| Microsoft.Agents.AI.AzureAI.Persistent (V1) | `GetAIAgent`/`GetAIAgentAsync` (with `AgentId`) | Fetches `PersistentAgent` via HTTP, then creates a local `ChatClientAgent` instance. | No |
| Microsoft.Agents.AI.AzureAI.Persistent (V1) | `CreateAIAgent`/`CreateAIAgentAsync` | Creates a remote agent first, then wraps it into a local `ChatClientAgent` instance. | No |
| Microsoft.Agents.AI.OpenAI | `GetAIAgent` (based on `AssistantClient` with `Assistant`) | Creates a local instance of `ChatClientAgent`. | Partial (Python uses `create_agent` from `BaseChatClient`). |
| Microsoft.Agents.AI.OpenAI | `GetAIAgent`/`GetAIAgentAsync` (with `AgentId`) | Fetches `Assistant` via HTTP, then creates a local `ChatClientAgent` instance. | No |
| Microsoft.Agents.AI.OpenAI | `CreateAIAgent`/`CreateAIAgentAsync` (based on `AssistantClient`) | Creates a remote agent first, then wraps it into a local `ChatClientAgent` instance. | No |
| Microsoft.Agents.AI.OpenAI | `CreateAIAgent` (based on `ChatClient`) | Creates a local instance of `ChatClientAgent`. | Yes (`create_agent` in `BaseChatClient`). |
| Microsoft.Agents.AI.OpenAI | `CreateAIAgent` (based on `OpenAIResponseClient`) | Creates a local instance of `ChatClientAgent`. | Yes (`create_agent` in `BaseChatClient`). |
Another difference between Python and .NET implementation is that in .NET `CreateAIAgent`/`GetAIAgent` methods are implemented as extension methods based on underlying SDK client, like `AIProjectClient` from Azure AI or `AssistantClient` from OpenAI:
```csharp
// Definition
publicstaticChatClientAgentCreateAIAgent(
thisAIProjectClientaiProjectClient,
stringname,
stringmodel,
stringinstructions,
string?description=null,
IList<AITool>?tools=null,
Func<IChatClient,IChatClient>?clientFactory=null,
IServiceProvider?services=null,
CancellationTokencancellationToken=default)
{}
// Usage
AIProjectClientaiProjectClient=new(newUri(endpoint),newAzureCliCredential());// Initialization of underlying SDK client
varnewAgent=awaitaiProjectClient.CreateAIAgentAsync(name:AgentName,model:deploymentName,instructions:AgentInstructions,tools:[tool]);// ChatClientAgent creation from underlying SDK client
// Alternative usage (same as extension method, just explicit syntax)
Python doesn't support extension methods. Currently `create_agent` method is defined on `BaseChatClient`, but this method only creates a local instance of `ChatAgent` and it can't create remote agents for providers that support it for a couple of reasons:
- It's defined as non-async.
-`BaseChatClient` implementation is stateful for providers like Azure AI or OpenAI Assistants. The implementation stores agent/assistant metadata like `AgentId` and `AgentName`, so currently it's not possible to create different instances of `ChatAgent` from a single `BaseChatClient` in case if the implementation is stateful.
## Decision Drivers
- API should be aligned between .NET and Python.
- API should be intuitive and consistent between backend providers in .NET and Python.
## Considered Options
Add missing implementations on the Python side. This should include the following:
### agent-framework-azure-ai (both V1 and V2)
- Add a `get_agent` method that accepts an underlying SDK agent instance and creates a local instance of `ChatAgent`.
- Add a `get_agent` method that accepts an agent identifier, performs an additional HTTP request to fetch agent data, and then creates a local instance of `ChatAgent`.
- Override the `create_agent` method from `BaseChatClient` to create a remote agent instance and wrap it into a local `ChatAgent`.
.NET:
```csharp
varagent1=newAIProjectClient(...).GetAIAgent(agentInstanceFromSdkType);// Creates a local ChatClientAgent instance from Azure.AI.Projects.OpenAI.AgentReference
varagent2=newAIProjectClient(...).GetAIAgent(agentName);// Fetches agent data, creates a local ChatClientAgent instance
varagent3=newAIProjectClient(...).CreateAIAgent(...);// Creates a remote agent, returns a local ChatClientAgent instance
```
### agent-framework-core (OpenAI Assistants)
- Add a `get_agent` method that accepts an underlying SDK agent instance and creates a local instance of `ChatAgent`.
- Add a `get_agent` method that accepts an agent name, performs an additional HTTP request to fetch agent data, and then creates a local instance of `ChatAgent`.
- Override the `create_agent` method from `BaseChatClient` to create a remote agent instance and wrap it into a local `ChatAgent`.
.NET:
```csharp
varagent1=newAssistantClient(...).GetAIAgent(agentInstanceFromSdkType);// Creates a local ChatClientAgent instance from OpenAI.Assistants.Assistant
varagent2=newAssistantClient(...).GetAIAgent(agentId);// Fetches agent data, creates a local ChatClientAgent instance
varagent3=newAssistantClient(...).CreateAIAgent(...);// Creates a remote agent, returns a local ChatClientAgent instance
```
### Possible Python implementations
Methods like `create_agent` and `get_agent` should be implemented separately or defined on some stateless component that will allow to create multiple agents from the same instance/place.
Possible options:
#### Option 1: Module-level functions
Implement free functions in the provider package that accept the underlying SDK client as the first argument (similar to .NET extension methods, but expressed in Python).
| Multiple implementations | One package may contain V1, V2, and other agent types. Function names like `create_agent` become ambiguous - which agent type does it create? | Each provider class is explicit: `AzureAIAgentsProvider` vs `AzureAIProjectAgentProvider` |
| Discoverability | Users must know to import specific functions from the package | IDE autocomplete on provider instance shows all available methods |
| Client reuse | SDK client must be passed to every function call: `create_agent(client, ...)`, `get_agent(client, ...)` | SDK client passed once at construction: `provider = Provider(client)` |
**Option 1 example:**
```python
from agent_framework.azure import create_agent, get_agent
agent1 = await create_agent(client, name="Agent1", ...) # Which agent type, V1 or V2?
The method names (`create_agent`, `get_agent`) do not explicitly mention "service" or "remote" because:
- In Python, the provider class name explicitly identifies the service (`AzureAIAgentsProvider`, `OpenAIAssistantProvider`), making additional qualifiers in method names redundant.
- In .NET, these are extension methods on `AIProjectClient` or `AssistantClient`, which already imply service operations.
### Provider Class Naming
| Package | Provider Class | SDK Client | Service |
Current method `create_agent` (python) / `CreateAIAgent` (.NET) can be renamed to `as_agent` (python) / `AsAIAgent` (.NET) to emphasize the conversion logic rather than creation/initialization logic and to avoid collision with `create_agent` method for remote calls.
```python
from agent_framework import ChatAgent
from agent_framework.openai import OpenAIChatClient
# Convert chat client to ChatAgent (no remote service involved)
client = OpenAIChatClient(model="gpt-4")
agent = client.as_agent(name="LocalAgent", instructions="...") # instead of create_agent
```
### Adding New Agent Types
Python:
1. Create provider class in appropriate package.
2. Implement `create_agent`, `get_agent`, `as_agent` as applicable.
.NET:
1. Create static class for extension methods.
2. Implement `CreateAIAgentAsync`, `GetAIAgentAsync`, `AsAIAgent` as applicable.
# Leveraging TypedDict and Generic Options in Python Chat Clients
## Context and Problem Statement
The Agent Framework Python SDK provides multiple chat client implementations for different providers (OpenAI, Anthropic, Azure AI, Bedrock, Ollama, etc.). Each provider has unique configuration options beyond the common parameters defined in `ChatOptions`. Currently, developers using these clients lack type safety and IDE autocompletion for provider-specific options, leading to runtime errors and a poor developer experience.
How can we provide type-safe, discoverable options for each chat client while maintaining a consistent API across all implementations?
## Decision Drivers
- **Type Safety**: Developers should get compile-time/static analysis errors when using invalid options
- **IDE Support**: Full autocompletion and inline documentation for all available options
- **Extensibility**: Users should be able to define custom options that extend provider-specific options
- **Consistency**: All chat clients should follow the same pattern for options handling
- **Provider Flexibility**: Each provider can expose its unique options without affecting the common interface
## Considered Options
- **Option 1: Status Quo - Class `ChatOptions` with `**kwargs`**
- **Option 2: TypedDict with Generic Type Parameters**
### Option 1: Status Quo - Class `ChatOptions` with `**kwargs`
The current approach uses a base `ChatOptions` Class with common parameters, and provider-specific options are passed via `**kwargs` or loosely typed dictionaries.
```python
# Current usage - no type safety for provider-specific options
response=awaitclient.get_response(
messages=messages,
temperature=0.7,
top_k=40,
random=42,# No validation
)
```
**Pros:**
- Simple implementation
- Maximum flexibility
**Cons:**
- No type checking for provider-specific options
- No IDE autocompletion for available options
- Runtime errors for typos or invalid options
- Documentation must be consulted for each provider
### Option 2: TypedDict with Generic Type Parameters (Chosen)
Each chat client is parameterized with a TypeVar bound to a provider-specific `TypedDict` that extends `ChatOptions`. This enables full type safety and IDE support.
- Users can extend options for their specific needs or advances in models
**Cons:**
- More complex implementation
- Some type: ignore comments needed for TypedDict field overrides
- Minor: Requires TypeVar with default (Python 3.13+ or typing_extensions)
> [NOTE!]
> In .NET this is already achieved through overloads on the `GetResponseAsync` method for each provider-specific options class, e.g., `AnthropicChatOptions`, `OpenAIChatOptions`, etc. So this does not apply to .NET.
### Implementation Details
1.**Base Protocol**: `ChatClientProtocol[TOptions]` is generic over options type, with default set to `ChatOptions` (the new TypedDict)
2.**Provider TypedDicts**: Each provider defines its options extending `ChatOptions`
They can even override fields with type=None to indicate they are not supported.
4.**Option Translation**: Common options are kept in place,and explicitly documented in the Options class how they are used. (e.g., `user` → `metadata.user_id`) in `_prepare_options` (for Anthropic) to preserve easy use of common options.
## Decision Outcome
Chosen option: **"Option 2: TypedDict with Generic Type Parameters"**, because it provides full type safety, excellent IDE support with autocompletion, and allows users to extend provider-specific options for their use cases. Extended this Generic to ChatAgents in order to also properly type the options used in agent construction and run methods.
See [typed_options.py](../../python/samples/02-agents/typed_options.py) for a complete example demonstrating the usage of typed options with custom extensions.
# Simplify Python Get Response API into a single method
## Context and Problem Statement
Currently chat clients must implement two separate methods to get responses, one for streaming and one for non-streaming. This adds complexity to the client implementations and increases the maintenance burden. This was likely done because the .NET version cannot do proper typing with a single method, in Python this is possible and this for instance is also how the OpenAI python client works, this would then also make it simpler to work with the Python version because there is only one method to learn about instead of two.
## Implications of this change
### Current Architecture Overview
The current design has **two separate methods** at each layer:
These are parallel methods on the agent, so consolidating the client methods would **not break** the agent API. You could keep `agent.run()` and `agent.run_stream()` unchanged while internally calling `get_response(stream=True/False)`.
All subclasses implement both `_inner_*` methods, except:
- OpenAI Assistants Client (and similar clients, such as Foundry Agents V1) - it implements `_inner_get_response` by calling `_inner_get_streaming_response`
### Implications of Consolidation
| Aspect | Impact |
|--------|--------|
| **Type Safety** | Overloads work well: `@overload` with `Literal[True]` → `AsyncIterable`, `Literal[False]` → `ChatResponse`. Runtime return type based on `stream` param. |
| **Breaking Change** | **Major breaking change** for anyone implementing custom chat clients. They'd need to update from 2 methods to 1 (or 2 inner methods to 1). |
| **Decorator Complexity** | All 3 decorator systems (function invocation, middleware, observability) would need refactoring to handle both paths in one wrapper. |
| **Code Reduction** | Significant reduction in _tools.py (~200 lines of near-duplicate code) and other decorators. |
| **Samples/Tests** | Many samples call `get_streaming_response()` directly - would need updates. |
| **Protocol Simplification** | `ChatClientProtocol` goes from 2 methods + 1 property to 1 method + 1 property. |
### Recommendation
The consolidation makes sense architecturally, but consider:
1.**The overload pattern with `stream: bool`** works well in Python typing:
2. **The decorator complexity** is the biggest concern. The current approach of separate decorators for separate methods is cleaner than conditional logic inside one wrapper.
## Decision Drivers
- Reduce code needed to implement a Chat Client, simplify the public API for chat clients
- Reduce code duplication in decorators and middleware
- Maintain type safety and clarity in method signatures
## Considered Options
1. Status quo: Keep separate methods for streaming and non-streaming
2. Consolidate into a single `get_response` method with a `stream` parameter
3. Option 2 plus merging `agent.run` and `agent.run_stream` into a single method with a `stream` parameter as well
## Option 1: Status Quo
- Good: Clear separation of streaming vs non-streaming logic
- Good: Aligned with .NET design, although it is already `run` for Python and `RunAsync` for .NET
- Bad: Code duplication in decorators and middleware
- Bad: More complex client implementations
## Option 2: Consolidate into Single Method
- Good: Simplified public API for chat clients
- Good: Reduced code duplication in decorators
- Good: Smaller API footprint for users to get familiar with
- Good: People using OpenAI directly already expect this pattern
- Bad: Increased complexity in decorators and middleware
- Bad: Less alignment with .NET design (`get_response(stream=True)` vs `GetStreamingResponseAsync`)
## Option 3: Consolidate + Merge Agent and Workflow Methods
- Good: Further simplifies agent and workflow implementation
- Good: Single method for all chat interactions
- Good: Smaller API footprint for users to get familiar with
- Good: People using OpenAI directly already expect this pattern
- Good: Workflows internally already use a single method (_run_workflow_with_tracing), so would eliminate public API duplication as well, with hardly any code changes
- Bad: More breaking changes for agent users
- Bad: Increased complexity in agent implementation
- Bad: More extensive misalignment with .NET design (`run(stream=True)` vs `RunStreamingAsync` in addition to `get_response` change)
## Misc
Smaller questions to consider:
- Should default be `stream=False` or `stream=True`? (Current is False)
- Default to `False` makes it simpler for new users, as non-streaming is easier to handle.
- Default to `False` aligns with existing behavior.
- Streaming tends to be faster, so defaulting to `True` could improve performance for common use cases.
- Should this differ between ChatClient, Agent and Workflows? (e.g., Agent and Workflow defaults to streaming, ChatClient to non-streaming)
When using agents, we often have cases where we want to pass some arbitrary services or data to an agent or some component in the agent execution stack.
These services or data are not necessarily known at compile time and can vary by the agent stack that the user has built.
E.g., there may be an agent decorator or chat client decorator that was added to the stack by the user, and an arbitrary payload needs to be passed to that decorator.
Since these payloads are related to components that are not integral parts of the agent framework, they cannot be added as strongly typed settings to the agent run options.
However, the payloads could be added to the agent run options as loosely typed 'features', that can be retrieved as needed.
In some cases certain classes of agents may support the same capability, but not all agents do.
Having the configuration for such a capability on the main abstraction would advertise the functionality to all users, even if their chosen agent does not support it.
The user may type test for certain agent types, and call overloads on the appropriate agent types, with the strongly typed configuration.
Having a feature collection though, would be an alternative way of passing such configuration, without needing to type check the agent type.
All agents that support the functionality would be able to check for the configuration and use it, simplifying the user code.
If the agent does not support the capability, that configuration would be ignored.
### Sample Scenario 1 - Per Run ChatMessageStore Override for hosting Libraries
We are building an agent hosting library, that can host any agent built using the agent framework.
Where an agent is not built on a service that uses in-service chat history storage, the hosting library wants to force the agent to use
the hosting library's chat history storage implementation.
This chat history storage implementation may be specifically tailored to the type of protocol that the hosting library uses, e.g. conversation id based storage or response id based storage.
The hosting library does not know what type of agent it is hosting, so it cannot provide a strongly typed parameter on the agent.
Instead, it adds the chat history storage implementation to a feature collection, and if the agent supports custom chat history storage, it retrieves the implementation from the feature collection and uses it.
```csharp
// Pseudo-code for an agent hosting library that supports conversation id based hosting.
Currently our base abstraction does not support structured output, since the capability is not supported by all agents.
For those agents that don't support structured output, we could add an agent decorator that takes the response from the underlying agent, and applies structured output parsing on top of it via an additional LLM call.
If we add structured output configuration as a feature, then any agent that supports structured output could retrieve the configuration from the feature collection and apply it, and where it is not supported, the configuration would simply be ignored.
We could add a simple StructuredOutputAgentFeature that can be added to the list of features and also be used to return the generated structured output.
Finally, we can add an extension method on `AIAgent` that can add the feature to the run options and check the feature for the structured output result and add the deserialized result to the response.
|Ability to modify registered options when progressing down the stack|✅ Supported|✅ Supported|❌ Not-Supported (IServiceProvider is read-only)|
|Already available in MEAI stack|❌ No|✅ Yes|❌ No|
|Ambiguity with existing AdditionalProperties|❌ Yes|✅ No|❌ Yes|
## IServiceProvider
Service Collections and Service Providers provide a very popular way to register and retrieve services by type and could be used as a way to pass features to agents and chat clients.
However, since IServiceProvider is read-only, it is not possible to modify the registered services when progressing down the execution stack.
E.g. an agent decorator cannot add additional services to the IServiceProvider passed to it when calling into the inner agent.
IServiceProvider also does not expose a way to list all services contained in it, making it difficult to copy services from one provider to another.
This lack of mutability makes IServiceProvider unsuitable for our use case, since we will not be able to use it to build sample scenario 2.
## AdditionalProperties dictionary
The AdditionalProperties dictionary is already available on various options classes in the agent framework as well as in the MEAI stack and
allows storing arbitrary key/value pairs, where the key is a string and the value is an object.
While FeatureCollection uses Type as a key, AdditionalProperties uses string keys.
This means that users need to agree on string keys to use for specific features, however it is also possible to use Type.FullName as a key by convention
to avoid key collisions, which is an easy convention to follow.
Since the value of AdditionalProperties is of type object, users need to cast the value to the expected type when retrieving it, which is also
a drawback, but when using the convention of using Type.FullName as a key, there is at least a clear expectation of what type to cast to.
If we choose the feature collection option, we need to decide on the design of the feature collection itself.
### Feature Collections extension points
We need to decide the set of actions that feature collections would be supported for. Here is the suggested list of actions:
**MAAI.AIAgent:**
1. GetNewThread
1. E.g. this would allow passing an already existing storage id for the thread to use, or an initialized custom chat message store to use.
1. DeserializeThread
1. E.g. this would allow passing an already existing storage id for the thread to use, or an initialized custom chat message store to use.
1. Run / RunStreaming
1. E.g. this would allow passing an override chat message store just for that run, or a desired schema for a structured output middleware component.
**MEAI.ChatClient:**
1. GetResponse / GetStreamingResponse
### Reconciling with existing AdditionalProperties
If we decide to add feature collections, separately from the existing AdditionalProperties dictionaries, we need to consider how to explain to users when to use each one.
One possible approach though is to have the one use the other under the hood.
AdditionalProperties could be stored as a feature in the feature collection.
Users would be able to retrieve additional properties from the feature collection, in addition to retrieving it via a dedicated AdditionalProperties property.
E.g. `features.Get<AdditionalPropertiesDictionary>()`
One challenge with this approach is that when setting a value in the AdditionalProperties dictionary, the feature collection would need to be created first if it does not already exist.
Since IAgentFeatureCollection is an interface, AgentRunOptions would need to have a concrete implementation of the interface to create, meaning that the user cannot decide.
It also means that if the user doesn't realise that AdditionalProperties is implemented using feature collections, they may set a value on AdditionalProperties, and then later overwrite the entire feature collection, losing the AdditionalProperties feature.
Options to avoid these issues:
1. Make `Features` readonly.
1. This would prevent the user from overwriting the feature collection after setting AdditionalProperties.
1. Since the user cannot set their own implementation of IAgentFeatureCollection, having an interface for it may not be necessary.
### Feature Collection Implementation
We have two options for implementing feature collections:
1. Create our own [IAgentFeatureCollection interface](https://github.com/microsoft/agent-framework/pull/2354/files#diff-9c42f3e60d70a791af9841d9214e038c6de3eebfc10e3997cb4cdffeb2f1246d) and [implementation](https://github.com/microsoft/agent-framework/pull/2354/files#diff-a435cc738baec500b8799f7f58c1538e3bb06c772a208afc2615ff90ada3f4ca).
2. Reuse the asp.net [IFeatureCollection interface](https://github.com/dotnet/aspnetcore/blob/main/src/Extensions/Features/src/IFeatureCollection.cs) and [implementation](https://github.com/dotnet/aspnetcore/blob/main/src/Extensions/Features/src/FeatureCollection.cs).
#### Roll our own
Advantages:
Creating our own IAgentFeatureCollection interface and implementation has the advantage of being more clearly associated with the agent framework and allows us to
improve on some of the design decisions made in asp.net core's IFeatureCollection.
Drawbacks:
It would mean a different implementation to maintain and test.
#### Reuse asp.net IFeatureCollection
Advantages:
Reusing the asp.net IFeatureCollection has the advantage of being able to reuse the well-established and tested implementation from asp.net
core. Users who are using agents in an asp.net core application may be able to pass feature collections from asp.net core to the agent framework directly.
Drawbacks:
While the package name is `Microsoft.Extensions.Features`, the namespaces of the types are `Microsoft.AspNetCore.Http.Features`, which may create confusion for users of agent framework who are not building web applications or services.
Users may rightly ask: Why do I need to use a class from asp.net core when I'm not building a web application / service?
The current design has some design issues that would be good to avoid. E.g. it does not distinguish between a feature being "not set" and "null". Get returns both as null and there is no tryget method.
Since the [default implementation](https://github.com/dotnet/aspnetcore/blob/main/src/Extensions/Features/src/FeatureCollection.cs) also supports value types, it throws for null values of value types.
A TryGet method would be more appropriate.
## Feature Layering
One possible scenario when adding support for feature collections is to allow layering of features by scope.
The following levels of scope could be supported:
1. Application - Application wide features that apply to all agents / chat clients
2. Artifact (Agent / ChatClient) - Features that apply to all runs of a specific agent or chat client instance
3. Action (GetNewThread / Run / GetResponse) - Feature that apply to a single action only
When retrieving a feature from the collection, the search would start from the most specific scope (Action) and progress to the least specific scope (Application), returning the first matching feature found.
Introducing layering adds some challenges:
- There may be multiple feature collections at the same scope level, e.g. an Agent that uses a ChatClient where both have their own feature collections.
- Do we layer the agent feature collection over the chat client feature collection (Application -> ChatClient -> Agent -> Run), or only use the agent feature collection in the agent (Application -> Agent -> Run), and the chat client feature collection in the chat client (Application -> ChatClient -> Run)?
- The appropriate base feature collection may change when progressing down the stack, e.g. when an Agent calls a ChatClient, the action feature collection stays the same, but the artifact feature collection changes.
- Who creates the feature collection hierarchy?
- Since the hierarchy changes as it progresses down the execution stack, and the caller can only pass in the action level feature collection, the callee needs to combine it with its own artifact level feature collection and the application level feature collection. Each action will need to build the appropriate feature collection hierarchy, at the start of its execution.
- For Artifact level features, it seems odd to pass them in as a bag of untyped features, when we are constructing a known artifact type and therefore can have typed settings.
- E.g. today we have a strongly typed setting on ChatClientAgentOptions to configure a ChatMessageStore for the agent.
- To avoid global statics for application level features, the user would need to pass in the application level feature collection to each artifact that they create.
- This would be very odd if the user also already has to strongly typed settings for each feature that they want to set at the artifact level.
### Layering Options
1. No layering - only a single feature collection is supported per action (the caller can still create a layered collection if desired, but the callee does not do any layering automatically).
1. Fallback is to any features configured on the artifact via strongly typed settings.
1. Full layering - support layering at all levels (Application -> Artifact -> Action).
1. Only apply applicable artifact level features when calling into that artifact.
1. Apply upstream artifact features when calling into downstream artifacts, e.g. Feature hierarchy in ChatClientAgent would be `Application -> Agent -> Run` and in ChatClient would be `Application -> ChatClient -> Agent -> Run` or `Application -> Agent -> ChatClient -> Run`
1. The user needs to provide the application level feature collection to each artifact that they create and artifact features are passed via strongly typed settings.
### Accessing application level features Options
We need to consider how application level features would be accessed if supported.
1. The user provides the application level feature collection to each artifact that the user constructs
1. Passing the application level feature collection to each artifact is tedious for the user.
1. There is a static application level feature collection that can be accessed globally.
1. Statics create issues with testing and isolation.
## Decisions
- Feature Collections Container: Use AdditionalProperties
- Feature Layering: No layering - only a single collection/dictionary is supported per action. Application layers can be added later if needed.
During an agent run, various components involved in the execution (middleware, filters, tools, nested agents, etc.) may need access to contextual information about the current run, such as:
1. The agent that is executing the run
2. The session associated with the run
3. The request messages passed to the agent
4. The run options controlling the agent's behavior
Additionally, some components may need to modify this context during execution, for example:
- Replacing the session with a different one
- Modifying the request messages before they reach the agent core
- Updating or replacing the run options entirely
Currently, there is no standardized way to access or modify this context from arbitrary code that executes during an agent run, especially from deeply nested call stacks where the context is not explicitly passed.
## Sample Scenario
When using an Agent as an AIFunction developers may want to pass context from the parent agent run to the child agent run. For example, the developer may want to copy chat history to the child agent, or share the same session across both agents.
To enable these scenarios, we need a way to access the parent agent run context, including e.g. the parent agent itself, the parent agent session, and the parent run options from function tool calls.
```csharp
public static AIFunction AsAIFunctionWithSessionPropagation(this ChatClientAgent agent, AIFunctionFactoryOptions? options = null)
{
Throw.IfNull(agent);
[Description("Invoke an agent to retrieve some information.")]
async Task<string> InvokeAgentAsync(
[Description("Input query to invoke the agent.")] string query,
CancellationToken cancellationToken)
{
// Get the session from the parent agent and pass it to the child agent.
var session = AIAgent.CurrentRunContext?.Session;
// Alternatively, the developer may want to create a new session but copy over the chat history from the parent agent.
// var parentChatHistory = AIAgent.CurrentRunContext?.Session?.GetService<IList<ChatMessage>>();
// if (parentChatHistory != null)
// {
// var chp = new InMemoryChatHistoryProvider();
// foreach (var message in parentChatHistory)
// {
// chp.Add(message);
// }
// session = agent.GetNewSession(chp);
// }
var response = await agent.RunAsync(query, session: session, cancellationToken: cancellationToken).ConfigureAwait(false);
- Components executing during an agent run need access to run context without explicit parameter passing through every layer
- Context should flow naturally across async calls without manual propagation
- The design should allow modification of context properties by agent decorators (e.g., replacing options or session)
- Solution should be consistent with patterns used in similar frameworks (e.g., `FunctionInvokingChatClient.CurrentContext``HttpContext.Current`, `Activity.Current`)
## Considered Options
- **Option 1**: Pass context explicitly through all method signatures
- **Option 2**: Use `AsyncLocal<T>` to provide ambient context accessible anywhere during the run
- **Option 3**: Use a combination of explicit parameters for `RunCoreAsync` and `AsyncLocal<T>` for ambient access
## Decision Outcome
Chosen option: **Option 3** - Combination of explicit parameters and AsyncLocal ambient access.
This approach provides the best of both worlds:
1. **Explicit parameters are passed to `RunCoreAsync`**: The core agent implementation receives the parameters explicitly, making it clear what data is available and enabling easy unit testing. Any modification of these in a decorator will require calling `RunAsync` on the inner agent with the updated parameters, which would result in the inner agent creating a new `AgentRunContext` instance.
```csharp
public async Task<AgentResponse> RunAsync(
IEnumerable<ChatMessage> messages,
AgentSession? session = null,
AgentRunOptions? options = null,
CancellationToken cancellationToken = default)
{
CurrentRunContext = new(this, session, messages as IReadOnlyCollection<ChatMessage> ?? messages.ToList(), options);
2. **`AsyncLocal<AgentRunContext?>` for ambient access**: The context is stored in an `AsyncLocal<T>` field, making it accessible from any code executing during the agent run via a static property.
The main scenario for this is to allow deeply nested components (e.g., tools, chat client middleware) to access the context without needing to pass it through every method signature. These are external components that cannot easily be modified to accept additional parameters. For internal components, we prefer passing any parameters explicitly.
```csharp
public static AgentRunContext? CurrentRunContext
{
get => s_currentContext.Value;
protected set => s_currentContext.Value = value;
}
```
### AgentRunContext Design
The `AgentRunContext` class encapsulates all run-related state:
```csharp
public class AgentRunContext
{
public AgentRunContext(
AIAgent agent,
AgentSession? session,
IReadOnlyCollection<ChatMessage> requestMessages,
AgentRunOptions? agentRunOptions)
public AIAgent Agent { get; }
public AgentSession? Session { get; }
public IReadOnlyCollection<ChatMessage> RequestMessages { get; }
public AgentRunOptions? RunOptions { get; }
}
```
Key design decisions:
- **All properties are read-only**: While some of the sub-properties on the provided properties (like `AgentRunOptions.AllowBackgroundResponses`) may be mutable, the `AgentRunContext` itself is immutable and we want to discourage anyone modifying the values in the context. Modifying the context is unlikely to result in the desired behavior, as the values will typically already have been used by the time any custom code accesses them.
### Benefits
1. **Ambient Access**: Any code executing during the run can access context via `AIAgent.CurrentRunContext` without needing explicit parameters
2. **Async Flow**: `AsyncLocal<T>` automatically flows across async/await boundaries
3. **Modifiability**: Components can modify or replace session, messages, or options as needed
4. **Testability**: The explicit parameter to `RunCoreAsync` makes unit testing straightforward
Structured output is a valuable aspect of any agent system, since it forces an agent to produce output in a required format that may include required fields.
This allows easily turning unstructured data into structured data using a general-purpose language model.
## Context and Problem Statement
Structured output is currently supported only by `ChatClientAgent` and can be configured in two ways:
**Approach 1: ResponseFormat + Deserialize**
Specify the SO type schema via the `ChatClientAgent{Run}Options.ChatOptions.ResponseFormat` property at agent creation or invocation time, then use `JsonSerializer.Deserialize<T>` to extract the structured data from the response text.
Note: `RunAsync<T>` is an instance method of `ChatClientAgent` and not part of the `AIAgent` base class since not all agents support structured output.
Approach 1 is perceived as cumbersome by the community, as it requires additional effort when using primitive or collection types - the SO schema may need to be wrapped in an artificial JSON object. Otherwise, the caller will encounter an error like _Invalid schema for response_format 'Movie': schema must be a JSON Schema of 'type: "object"', got 'type: "array"'_.
This occurs because OpenAI and compatible APIs require a JSON object as the root schema.
Approach 1 is also necessary in scenarios where (a) agents can only be configured with SO at creation time (such as with `AIProjectClient`), (b) the SO type is not known at compile time, or (c) the JSON schema is represented as text (for declarative agents) or as a `JsonElement`.
Approach 2 is more convenient and works seamlessly with primitives and collections. However, it requires the SO type to be known at compile time, making it less flexible.
Additionally, since the `RunAsync<T>` methods are instance methods of `ChatClientAgent` and are not part of the `AIAgent` base class, applying decorators like `OpenTelemetryAgent` on top of `ChatClientAgent` prevents users from accessing `RunAsync<T>`, meaning structured output is not available with decorated agents.
Given the different scenarios above in which structured output can be used, there is no one-size-fits-all solution. Each approach has its own advantages and limitations,
and the two can complement each other to provide a comprehensive structured output experience across various use cases.
## Approaches Overview
1. SO usage via `ResponseFormat` property
2. SO usage via `RunAsync<T>` generic method
## 1. SO usage via `ResponseFormat` property
This approach should be used in the following scenarios:
- 1.1 SO result as text is sufficient as is, and deserialization is not required
- 1.2 SO for inter-agent collaboration
- 1.3 SO can only be configured at agent creation time (such as with `AIProjectClient`)
- 1.4 SO type is not known at compile time and represented by System.Type
- 1.5 SO is represented by JSON schema and there's no corresponding .NET type either at compile time or at runtime
- 1.6 SO in streaming scenarios, where the SO response is produced in parts
**Note: Primitives and arrays are not supported by this approach.**
When a caller provides a schema via `ResponseFormat`, they are explicitly telling the framework what schema to use. The framework passes that schema through as-is and
is not responsible for transforming it. Because the framework does not own the schema, it cannot wrap primitives or arrays into a JSON object to satisfy API requirements,
nor can it unwrap the response afterward - the caller controls the schema and is responsible for ensuring it is compatible with the underlying API.
This is in contrast to the `RunAsync<T>` approach (section 2), where the caller provides a type `T` and says "make it work." In that case, the caller does not
dictate the schema - the framework infers the schema from `T`, owns the end-to-end pipeline (schema generation, API invocation, and deserialization), and can
therefore wrap and unwrap primitives and arrays transparently.
Additionally, in streaming scenarios (1.6), the framework cannot reliably unwrap a response it did not wrap, since it has no way of knowing whether the caller wrapped the schema.Wrapping and unwrapping can only be done safely when the framework owns the entire lifecycle - from schema creation through deserialization — which is only the case with `RunAsync<T>`.
If a caller needs to work with primitives or arrays via the `ResponseFormat` approach, they can easily create a wrapper type around them:
```csharp
public class MovieListWrapper
{
public List<string> Movies { get; set; }
}
```
### 1.1 SO result as text is sufficient as is, and deserialization is not required
In this scenario, the caller only needs the raw JSON text returned by the model and does not need to deserialize it into a .NET type.
The SO schema is specified via `ResponseFormat` at agent creation or invocation time, and the response text is consumed directly from the `AgentResponse`.
In this scenario, the SO schema can only be configured at agent creation time (such as with `AIProjectClient`) and cannot be changed on a per-run basis.
The caller specifies the `ResponseFormat` when creating the agent, and all subsequent invocations use the same schema.
```csharp
AIProjectClient client = ...;
AIAgent agent = await client.CreateAIAgentAsync(model: "<model>", new ChatClientAgentOptions()
### 1.4 SO type not known at compile time and represented by System.Type
In this scenario, the SO type is not known at compile time and is provided as a `System.Type` at runtime. This is useful for dynamic scenarios where the schema is determined programmatically,
such as when building tooling or frameworks that work with user-defined types.
```csharp
Type soType = GetStructuredOutputTypeFromConfiguration(); // e.g., typeof(PersonInfo)
### 1.5 SO represented by JSON schema with no corresponding .NET type
In this scenario, the SO schema is represented as raw JSON schema text or a `JsonElement`, and there is no corresponding .NET type available at compile time or runtime.
This is typical for declarative agents or scenarios where schemas are loaded from external configuration.
```csharp
// JSON schema provided as a string, e.g., loaded from a configuration file
// Consume the SO result as text since there's no .NET type to deserialize into
Console.WriteLine(response.Text);
```
### 1.6 SO in streaming scenarios
In this scenario, the SO response is produced incrementally in parts via streaming. The caller specifies the `ResponseFormat` and consumes the response chunks as they arrive.
Deserialization is performed after all chunks have been received.
IAsyncEnumerable<AgentResponseUpdate> updates = agent.RunStreamingAsync("Please provide information about John Smith, who is a 35-year-old software engineer.");
This approach provides a convenient way to work with structured output on a per-run basis when the target type is known at compile time and a typed instance of the result
is required.
### Decision Drivers
1. Support arrays and primitives as SO types
2. Support complex types as SO types
3. Work with `AIAgent` decorators (e.g., `OpenTelemetryAgent`)
4. Enable SO for all AI agents, regardless of whether they natively support it
### Considered Options
1. `RunAsync<T>` as an instance method of `AIAgent` class delegating to virtual `RunCoreAsync<T>`
2. `RunAsync<T>` as an extension method using feature collection
3. `RunAsync<T>` as a method of the new `ITypedAIAgent` interface
4. `RunAsync<T>` as an instance method of `AIAgent` class working via the new `AgentRunOptions.ResponseFormat` property
### 1. `RunAsync<T>` as an instance method of `AIAgent` class delegating to virtual `RunCoreAsync<T>`
This option adds the `RunAsync<T>` method directly to the `AIAgent` base class.
throw new NotSupportedException($"The agent of type '{this.GetType().FullName}' does not support typed responses.");
}
}
```
Agents with native SO support override the `RunCoreAsync<T>` method to provide their implementation. If not overridden, the method throws a `NotSupportedException`.
Users will call the generic `RunAsync<T>` method directly on the agent:
```csharp
AIAgent agent = chatClient.AsAIAgent(name: "HelpfulAssistant", instructions: "You are a helpful assistant.");
AgentResponse<PersonInfo> response = await agent.RunAsync<PersonInfo>("Please provide information about John Smith, who is a 35-year-old software engineer.");
```
Decision drivers satisfied:
1. Support arrays and primitives as SO types
2. Support complex types as SO types
3. Work with `AIAgent` decorators (e.g., `OpenTelemetryAgent`)
4. Enable SO for all AI agents, regardless of whether they natively support it
Pros:
- The `AIAgent.RunAsync<T>` method is easily discoverable.
- Both the SO decorator and `ChatClientAgent` have compile-time access to the type `T`, allowing them to use the native `IChatClient.GetResponseAsync<T>` API, which handles primitives and collections seamlessly.
Cons:
- Agents without native SO support will still expose `RunAsync<T>`, which may be misleading.
- `ChatClientAgent` exposing `RunAsync<T>` may be misleading when the underlying chat client does not support SO.
- All `AIAgent` decorators must override `RunCoreAsync<T>` to properly handle `RunAsync<T>` calls.
### 2. `RunAsync<T>` as an extension method using feature collection
This option uses the Agent Framework feature collection (implemented via `AgentRunOptions.AdditionalProperties`) to pass a `StructuredOutputFeature` to agents, signaling that SO is requested.
Agents with native SO support check for this feature. If present, they read the target type, build the schema, invoke the underlying API, and store the response back in the feature.
```csharp
public class StructuredOutputFeature
{
public StructuredOutputFeature(Type outputType)
{
this.OutputType = outputType;
}
[JsonIgnore]
public Type OutputType { get; set; }
public JsonSerializerOptions? SerializerOptions { get; set; }
public AgentResponse? Response { get; set; }
}
```
The `RunAsync<T>` extension method for `AIAgent` adds this feature to the collection.
```csharp
public static async Task<AgentResponse<T>> RunAsync<T>(
((options ??= new AgentRunOptions()).AdditionalProperties ??= []).Add(typeof(StructuredOutputFeature).FullName!, structuredOutputFeature);
var response = await agent.RunAsync(messages, session, options, cancellationToken).ConfigureAwait(false);
if (structuredOutputFeature.Response is not null)
{
return new StructuredOutputResponse<T>(structuredOutputFeature.Response, response, serializerOptions);
}
throw new InvalidOperationException("No structured output response was generated by the agent.");
}
```
Users will call the `RunAsync<T>` extension method directly on the agent:
```csharp
AIAgent agent = chatClient.AsAIAgent(name: "HelpfulAssistant", instructions: "You are a helpful assistant.");
AgentResponse<PersonInfo> response = await agent.RunAsync<PersonInfo>("Please provide information about John Smith, who is a 35-year-old software engineer.");
```
Decision drivers satisfied:
1. Support arrays and primitives as SO types
2. Support complex types as SO types
3. Work with `AIAgent` decorators (e.g., `OpenTelemetryAgent`)
4. Enable SO for all AI agents, regardless of whether they natively support it
Pros:
- The `RunAsync<T>` extension method is easily discoverable.
- The `AIAgent` public API surface remains unchanged.
- No changes required to `AIAgent` decorators.
Cons:
- Agents without native SO support will still expose `RunAsync<T>`, which may be misleading.
- `ChatClientAgent` exposing `RunAsync<T>` may be misleading when the underlying chat client does not support SO.
### 3. `RunAsync<T>` as a method of the new `ITypedAIAgent` interface
This option defines a new `ITypedAIAgent` interface that agents with SO support implement. Agents without SO support do not implement it, allowing users to check for SO capability via interface detection.
The interface:
```csharp
public interface ITypedAIAgent
{
Task<AgentResponse<T>> RunAsync<T>(
IEnumerable<ChatMessage> messages,
AgentSession? session = null,
JsonSerializerOptions? serializerOptions = null,
AgentRunOptions? options = null,
CancellationToken cancellationToken = default);
...
}
```
Agents with SO support implement this interface:
```csharp
public sealed partial class ChatClientAgent : AIAgent, ITypedAIAgent
{
public async Task<AgentResponse<T>> RunAsync<T>(
IEnumerable<ChatMessage> messages,
AgentSession? session = null,
JsonSerializerOptions? serializerOptions = null,
AgentRunOptions? options = null,
CancellationToken cancellationToken = default)
{
...
}
}
```
However, `ChatClientAgent` presents a challenge: it can work with chat clients that either support or do not support SO. Implementing the interface does not guarantee
the underlying chat client supports SO, which undermines the core idea of using interface detection to determine SO capability.
Additionally, to allow users to access interface methods on decorated agents, all decorators must implement `ITypedAIAgent`. This makes it difficult for users to
determine whether the underlying agent actually supports SO, further weakening the purpose of this approach.
Furthermore, users would have to probe the agent type to check if it implements the `ITypedAIAgent` interface and cast it accordingly to access the `RunAsync<T>` methods.
This adds friction to the user experience. A `RunAsync<T>` extension method for `AIAgent` could be provided to alleviate that.
Given these drawbacks, this option is more complex to implement than the others without providing clear benefits.
Decision drivers satisfied:
1. Support arrays and primitives as SO types
2. Support complex types as SO types
3. Work with `AIAgent` decorators (e.g., `OpenTelemetryAgent`)
4. Enable SO for all AI agents, regardless of whether they natively support it
Pros:
- Both the SO decorator and `ChatClientAgent` have compile-time access to the type `T`, allowing them to use the native `IChatClient.GetResponseAsync<T>` API, which handles primitives and collections seamlessly.
Cons:
- `ChatClientAgent` implementing `ITypedAIAgent` may be misleading when the underlying chat client does not support SO.
- All `AIAgent` decorators must implement `ITypedAIAgent` to handle `RunAsync<T>` calls.
- Decorators implementing the interface may mislead users into thinking the underlying agent natively supports SO.
- Agents must implement all members of `ITypedAIAgent`, not just a core method.
- Users must check the agent type and cast to `ITypedAIAgent` to access `RunAsync<T>`.
### 4. `RunAsync<T>` as an instance method of `AIAgent` class working via the new `AgentRunOptions.ResponseFormat` property
This option adds a `ResponseFormat` property of type `ChatResponseFormat` to `AgentRunOptions`. Agents that support SO check for the presence of
this property in the options passed to `RunAsync` to determine whether structured output is requested. If present, they use the schema from `ResponseFormat`
to invoke the underlying API and obtain the SO response.
```csharp
public class AgentRunOptions
{
public ChatResponseFormat? ResponseFormat { get; set; }
}
```
Additionally, a generic `RunAsync<T>` method is added to `AIAgent` that initializes the `ResponseFormat` based on the type `T` and delegates to the non-generic `RunAsync`.
return new AgentResponse<T>(response, serializerOptions);
}
}
```
Users call the generic `RunAsync<T>` method directly on the agent:
```csharp
AIAgent agent = chatClient.AsAIAgent(name: "HelpfulAssistant", instructions: "You are a helpful assistant.");
AgentResponse<PersonInfo> response = await agent.RunAsync<PersonInfo>("Please provide information about John Smith, who is a 35-year-old software engineer.");
```
Decision drivers satisfied:
1. Support arrays and primitives as SO types
2. Support complex types as SO types
3. Work with `AIAgent` decorators (e.g., `OpenTelemetryAgent`)
4. Enable SO for all AI agents, regardless of whether they natively support it
Pros:
- The `AIAgent.RunAsync<T>` method is easily discoverable.
- No changes required to `AIAgent` decorators
Cons:
- Agents without native SO support will still expose `RunAsync<T>`, which may be misleading.
- `ChatClientAgent` exposing `RunAsync<T>` may be misleading when the underlying chat client does not support SO.
| Decorator changes | ❌ All decorators must override `RunCoreAsync<T>` | ✅ No changes required | ❌ All decorators must implement `ITypedAIAgent` | ✅ No changes required to decorators |
| Primitives/collections handling | ✅ Native support via `IChatClient.GetResponseAsync<T>` | ❌ Must wrap/unwrap internally | ✅ Native support via `IChatClient.GetResponseAsync<T>` | ❌ Must wrap/unwrap internally |
| Misleading API exposure | ❌ Agents without SO still expose `RunAsync<T>` | ❌ Agents without SO still expose `RunAsync<T>` | ❌ Interface on `ChatClientAgent` may be misleading | ❌ Agents without SO still expose `RunAsync<T>` |
| Implementation burden | ❌ Decorators must override method | ❌ Must handle schema wrapping | ❌ Agents must implement all interface members | ✅ Delegates to existing `RunAsync` via `ResponseFormat` |
## Cross-Cutting Aspects
1. **The `useJsonSchemaResponseFormat` parameter**: The `ChatClientAgent.RunAsync<T>` method has this parameter to enable structured output on LLMs that do not natively support it.
It works by adding a user message like "Respond with a JSON value conforming to the following schema:" along with the JSON schema. However, this approach has not been reliable historically. The recommendation is not to carry this parameter forward, regardless of which option is chosen.
2. **Primitives and array types handling**: There are a few options for how primitive and array types can be handled in the Agent Framework:
1. **Never wrap**, regardless of whether the schema is provided via `ResponseFormat` or `RunAsync<T>`.
- Pro: No changes needed; user has full control.
- Pro: No issues with unwrapping in streaming scenarios.
- Con: User must wrap manually.
2. **Always wrap**, regardless of whether the schema is provided via `ResponseFormat` or `RunAsync<T>`.
- Pro: Consistent wrapping behavior; no manual wrapping needed.
- Con: Inconsistent unwrapping behavior; it may be unexpected to have SO result wrapped when schema is provided via `ResponseFormat`.
- Con: Impossible to know if SO result is wrapped to unwrap it in streaming scenarios.
3. **Wrap only for `RunAsync<T>`** and do not wrap the schema provided via `ResponseFormat`.
- Pro: No unexpectedly wrapped result when schema is provided via `ResponseFormat`.
- Pro: Solves the problem with unwrapping in streaming scenarios.
4. **User decides** whether to wrap schema provided via `ResponseFormat` using a new `wrapPrimitivesAndArrays` property of `ChatResponseFormatJson`. For SO provided via `RunAsync<T>`, AF always wraps.
- Pro: No manual wrapping needed; just flip a switch.
- Pro: Solves the problem with unwrapping in streaming scenarios.
- Con: Extends the public API surface.
3. **Structured output for agents without native SO support**: Some AI agents in AF do not support structured output natively. This is either because it is not part of the protocol (e.g., A2A agent) or because the agents use LLMs without structured output capabilities.
To address this gap, AF can provide the `StructuredOutputAgent` decorator. This decorator wraps any `AIAgent` and adds structured output support by obtaining the text response from the decorated agent and delegating it to a configured chat client for JSON transformation.
```csharp
public class StructuredOutputAgent : DelegatingAIAgent
{
private readonly IChatClient _chatClient;
public StructuredOutputAgent(AIAgent innerAgent, IChatClient chatClient)
return new StructuredOutputAgentResponse(soResponse, textResponse);
}
}
```
The decorator preserves the original response from the decorated agent and surfaces it via the `OriginalResponse` property on the returned `StructuredOutputAgentResponse`.
This allows users to access both the original unstructured response and the new structured response when using this decorator.
```csharp
public class StructuredOutputAgentResponse : AgentResponse
AIAgent baseAgent = meaiChatClient.AsAIAgent(name: "HelpfulAssistant", instructions: "You are a helpful assistant.");
// Register the StructuredOutputAgent decorator during agent building
AIAgent agent = baseAgent
.AsBuilder()
.UseStructuredOutput(meaiChatClient)
.Build();
AgentResponse<PersonInfo> response = await agent.RunAsync<PersonInfo>("Please provide information about John Smith, who is a 35-year-old software engineer.");
It was decided to keep both approaches for structured output - via `ResponseFormat` and via `RunAsync<T>` since they serve different scenarios and use cases.
For the `RunAsync<T>` approach, option 4 was selected, which adds a generic `RunAsync<T>` method to `AIAgent` that works via the new `AgentRunOptions.ResponseFormat` property.
This was chosen for its simplicity and because no changes are required to existing `AIAgent` decorators.
For cross-cutting aspects, the `useJsonSchemaResponseFormat` parameter will not be carried forward due to reliability issues.
For handling primitives and array types, option 3 was selected: wrap only for `RunAsync<T>` and do not wrap the schema provided via `ResponseFormat`.
This avoids the issues described in the Approach 1 section note.
Finally, it was decided not to include the `StructuredOutputAgent` decorator in the framework, since the reliability of producing structured output via an additional
LLM call may not be sufficient for all scenarios. Instead, this pattern is provided as a sample to demonstrate how structured output can be achieved for agents without native support,
giving users a reference implementation they can adapt to their own requirements.
# AdditionalProperties for AIAgent and AgentSession
## Context and Problem Statement
The `AIAgent` base class currently exposes `Id`, `Name`, and `Description` as its core metadata properties, and `AgentSession` exposes only a `StateBag` property.
Neither type has a mechanism for attaching arbitrary metadata, such as protocol-specific descriptors (e.g., A2A agent cards), hosting attributes, session-level tags, or custom user-defined metadata for discovery and routing.
Other types in the framework already carry `AdditionalProperties` — notably `AgentRunOptions`, `AgentResponse`, and `AgentResponseUpdate` — all using `AdditionalPropertiesDictionary` from `Microsoft.Extensions.AI`.
Adding a similar property to `AIAgent` and `AgentSession` would give both types a consistent, extensible metadata surface.
- **Consistency**: Other core types (`AgentRunOptions`, `AgentResponse`, `AgentResponseUpdate`) already expose `AdditionalProperties`. `AIAgent` and `AgentSession` are the major abstractions that lack this.
- **Extensibility**: Hosting libraries, protocol adapters (A2A, AG-UI), and discovery mechanisms need a place to attach agent-level and session-level metadata without subclassing.
- **Simplicity**: The solution should be easy to understand and use; avoid over-engineering.
- **Minimal breaking change**: The addition should not require changes to existing agent implementations.
- **Clear semantics**: Users should understand what `AdditionalProperties` on an agent or session means and how it differs from `AdditionalProperties` on `AgentRunOptions`.
## Considered Options
### Surface Area
- **Option A**: Public get-only property, auto-initialized (`AdditionalPropertiesDictionary AdditionalProperties { get; } = new()`) on both `AIAgent` and `AgentSession`
- **Option B**: Public get/set nullable property (`AdditionalPropertiesDictionary? AdditionalProperties { get; set; }`) on both `AIAgent` and `AgentSession`
- **Option C**: Constructor-injected dictionary with public get-only accessor on both `AIAgent` and `AgentSession`
- **Option D**: External container/wrapper object — metadata lives outside `AIAgent` and `AgentSession`; no changes to the base classes
### Semantics
- **Option 1**: Metadata only — describes the agent or session; not propagated when calling `IChatClient`
- **Option 2**: Passed down the stack — merged into `ChatOptions.AdditionalProperties` during `ChatClientAgent` runs
## Decision Outcome
The chosen option is **Option D + Option 1**: an external container/wrapper object, used purely as metadata.
### Consequences
- Good, because `AIAgent` and `AgentSession` remain unchanged, avoiding any increase to the core framework surface area while still enabling extensible metadata.
- Good, because an external wrapper (owned by hosting/protocol libraries or user code, not the `AIAgent` / `AgentSession` base classes) can internally use `AdditionalPropertiesDictionary` to stay consistent with existing patterns on `AgentRunOptions`, `AgentResponse`, and `AgentResponseUpdate`.
- Good, because metadata-only semantics keep a clean separation from per-run extensibility (`AgentRunOptions.AdditionalProperties`) and avoid unexpected side effects during agent execution.
- Good, because no additional allocation occurs on `AIAgent` or `AgentSession` when no metadata is needed; external wrappers can be created only when metadata is required.
- Bad, because callers and libraries must manage and pass around both the agent/session instance and its associated metadata wrapper, keeping them correctly associated.
- Bad, because different hosting or protocol layers may define their own wrapper types, which can fragment the ecosystem unless conventions are agreed upon.
## Pros and Cons of the Options
### Option A — Public get-only property, auto-initialized
The property is always non-null and ready to use. Users add metadata after construction.
```csharp
public abstract partial class AIAgent
{
public AdditionalPropertiesDictionary AdditionalProperties { get; } = new();
}
public abstract partial class AgentSession
{
public AdditionalPropertiesDictionary AdditionalProperties { get; } = new();
- Good, because it is consistent with the existing `AdditionalProperties` pattern on `AgentRunOptions` and `AgentResponse`.
- Good, because it avoids allocation when no metadata is needed.
- Bad, because every consumer must null-check before reading or writing.
- Bad, because the entire dictionary can be replaced, risking accidental loss of metadata set by other components (e.g., a hosting library sets metadata, then user code replaces the dictionary).
### Option C — Constructor-injected with public get
The dictionary is provided at construction time and exposed as get-only.
```csharp
public abstract partial class AIAgent
{
public AdditionalPropertiesDictionary AdditionalProperties { get; }
- Good, because an agent's metadata can be established before any code runs against it.
- Bad, because `AdditionalPropertiesDictionary` has no read-only variant, so the constructor-injection pattern gives a false sense of immutability — callers can still mutate the dictionary contents after construction.
- Bad, because it requires adding a constructor parameter to the abstract base classes, which is a source-breaking change for all existing `AIAgent` and `AgentSession` subclasses (even with a default value, it changes the constructor signature that derived classes chain to).
- Bad, because it is more complex with little practical benefit over Option A, since post-construction mutation is equally possible.
### Option D — External container/wrapper object
Rather than adding `AdditionalProperties` to `AIAgent` or `AgentSession`, users wrap the agent or session in a container object that carries both the instance and any associated metadata. No changes to the base classes are required.
```csharp
public class AgentWithMetadata
{
public required AIAgent Agent { get; init; }
public AdditionalPropertiesDictionary? AdditionalProperties { get; set; }
}
public class SessionWithMetadata
{
public required AgentSession Session { get; init; }
public AdditionalPropertiesDictionary? AdditionalProperties { get; set; }
- Good, because it requires no changes to `AIAgent` or `AgentSession`, avoiding any risk of breaking existing implementations.
- Good, because metadata is clearly external to the agent and session, eliminating any ambiguity about whether it might be passed down the execution stack.
- Good, because the container pattern gives the user full control over the metadata lifecycle and serialization.
- Bad, because it is not discoverable — users must know about the container convention; there is no built-in API surface guiding them.
### Option 1 — Metadata only
`AdditionalProperties` on `AIAgent` and `AgentSession` is descriptive metadata. It is **not** automatically propagated when the agent calls downstream services such as `IChatClient`.
- Good, because it keeps a clean separation of concerns: agent/session-level metadata vs. per-run options.
- Good, because it avoids unintended side effects — metadata added for discovery or hosting won't leak into LLM requests.
- Good, because per-run extensibility is already served by `AgentRunOptions.AdditionalProperties` (see [ADR 0014](0014-feature-collections.md)), so there is no gap.
- Neutral, because users who want to pass agent metadata to the chat client can still do so manually via `AgentRunOptions`.
### Option 2 — Passed down the stack
`AdditionalProperties` on `AIAgent` and `AgentSession` are automatically merged into `ChatOptions.AdditionalProperties` (or similar) when `ChatClientAgent` invokes the underlying `IChatClient`.
- Good, because it provides an automatic way to send agent-level configuration to the LLM provider.
- Bad, because it conflates metadata (describing the agent) with operational parameters (controlling LLM behavior), leading to potential confusion.
- Bad, because it risks leaking unrelated metadata into LLM calls (e.g., hosting tags, discovery URLs).
- Bad, because it would be `ChatClientAgent`-specific behavior on a base-class property, creating inconsistency for non-`ChatClientAgent` implementations.
- Bad, because it duplicates the purpose of `AgentRunOptions.AdditionalProperties`, which already serves as the per-run extensibility point for passing data down the stack.
## Serialization Considerations
`AIAgent` instances are not typically serialized, so `AdditionalProperties` on `AIAgent` does not raise serialization concerns.
`AgentSession` instances, however, are routinely serialized and deserialized — for example, to persist conversation state across application restarts. Adding `AdditionalProperties` to `AgentSession` introduces a serialization challenge: `AdditionalPropertiesDictionary` is a `Dictionary<string, object?>`, and `object?` values do not carry enough type information for the JSON deserializer to reconstruct the original CLR types.
### Default behavior — JsonElement round-tripping
By default, when an `AgentSession` with `AdditionalProperties` is serialized and later deserialized, any complex objects stored as values in the dictionary will be deserialized as `JsonElement` rather than their original types. This is the same behavior exhibited by `ChatMessage.AdditionalProperties` and other `AdditionalPropertiesDictionary` usages in `Microsoft.Extensions.AI`, and is the approach we will follow.
### Custom serialization via JsonSerializerOptions
`AIAgent.SerializeSessionAsync` and `AIAgent.DeserializeSessionAsync` already accept an optional `JsonSerializerOptions` parameter. Users who need strongly-typed round-tripping of `AdditionalProperties` values can supply custom options with appropriate converters or type info resolvers. This is non-trivial to implement but provides full control over deserialization behavior when needed.
## More Information
- [ADR 0014 — Feature Collections](0014-feature-collections.md) established that `AdditionalProperties` on `AgentRunOptions` serves as the per-run extensibility mechanism. The proposed agent-level and session-level properties serve a complementary, distinct purpose: static metadata describing the agent or session itself.
- `AdditionalPropertiesDictionary` is defined in `Microsoft.Extensions.AI` and is already a dependency of `Microsoft.Agents.AI.Abstractions`. No new package references are needed.
- Type-safe access is available via the existing `AdditionalPropertiesExtensions` helper methods (`Add<T>`, `TryGetValue<T>`, `Contains<T>`, `Remove<T>`), which use `typeof(T).FullName` as the dictionary key.
Serializing AgentSessions is done today by calling SerializeSession on the AIAgent instance and deserialization
is done via the DeserializeSession method on the AIAgent instance.
This approach has some drawbacks:
1. It requires each AgentSession implementation to implement its own serialization logic. This can lead to inconsistencies and errors if not done correctly.
1. It means that only one serialization format can be supported at a time. If we want to support multiple formats (e.g., JSON, XML, binary), we would need to implement separate serialization logic for each format.
1. It is not possible to serialize and deserialize lists of AgentSessions, since each need to be handled individually.
1. Users may not realise that they need to call these specific methods to serialize/deserialize AgentSessions.
The reason why this approach was chosen initially is that AgentSessions may have behaviors that are attached to them and only the agent knows what behaviors to attach.
These behaviors also have their own state that are attached to the AgentSession.
The behaviors may have references to SDKs or other resources that cannot be created via standard deserialization mechanisms.
E.g. an AgentSession may have a custom ChatMessageStore that knows how to store chat history in a specific storage backend and has a reference to the SDK client for that backend.
When deserializing the AgentSession, we need to make sure that the ChatMessageStore is created with the correct SDK client.
## Decision Drivers
- A. Ability to continue to support custom behaviors (AIContextProviders / ChatHistoryProviders).
- B. Ability to serialize and deserialize AgentSessions via standard serialization mechanisms, e.g. JsonSerializer.Serialize and JsonSerializer.Deserialize.
- C. Ability for the caller to access custom providers.
## Considered Options
- Option 1: Separate state from behavior, serialize state only and re-attach behavior on first usage
- Option 2: Separate state from behavior, and only have state on AgentSession
- Option 3: Keep the current approach of custom Serialize/Deserialize methods
### Option 1: Separate state from behavior, serialize state only and re-attach behavior on first usage
Decision Drivers satisfied: A, B and C (C only partially)
Have separate properties on the AgentSession for state and behavior and mark the behavior property with [JsonIgnore].
After deserializing the AgentSession, the behavior is null and when the AgentSession is first used by the Agent, the behavior is created and attached to the AgentSession.
This requires polymorphic deserialization to be supported, so that the correct AgentSession subclass and the correct behavior state is created during deserialization.
Since the implementations for AgentSessions and their behaviors are not all known at compile time, we need a way to register custom AgentSession types and their corresponding behavior types for serialization with System.Text.Json on our JsonUtilities helpers.
A drawback of this approach is that the AgentSession is in an incomplete state after deserialization until it is first used,
so if a user was to call `GetService<MyBehavior>()` on the AgentSession before it is used by the Agent, it would return null.
Behaviors like ChatMessageStore and AIContextProviders would need to change to support taking state as input and exposing state publicly.
```csharp
public class ChatClientAgentSession
{
...
public ChatMessageStoreState ChatMessageStoreState { get; }
public ChatMessageStore? ChatMessageStore { get; }
public InMemoryChatMessageStore(InMemoryChatMessageStoreState? state)
{
this._state = state ?? new InMemoryChatMessageStoreState();
}
public override InMemoryChatMessageStoreState State => this._state;
...
}
```
ChatClientAgent factories would need to change to support creating behaviors based on state:
```csharp
public Func<ChatMessageStoreFactoryContext, ChatMessageStore>? ChatMessageStoreFactory { get; set; }
public class ChatMessageStoreFactoryContext
{
public ChatMessageStoreState? State { get; set; }
}
```
The run behavior of the ChatClientAgent would be as follows:
1. If an AgentSession is provided, check if the ChatMessageStore property is null.
1. If it is, check if the ChatMessageStoreState property is null.
1. If ChatMessageStoreState is null, check if there is a provided ChatMessageStoreFactory.
1. If there is, call it with a ChatMessageStoreFactoryContext containing null State to create a default ChatMessageStore behavior, and update the AgentSession with the created behavior and its state.
2. If there is not, create a default InMemoryChatMessageStore behavior, and update the AgentSession with the created behavior and its state.
1. If ChatMessageStoreState is not null, check if there is a provided ChatMessageStoreFactory.
1. If there is, call it with a ChatMessageStoreFactoryContext containing the State to create a ChatMessageStore behavior based on the state.
2. If there is not, create an InMemoryChatMessageStore behavior based on the State.
### Option 2: Separate state from behavior, and only have state on AgentSession
Decision Drivers satisfied: A, B and C.
This is similar to Option 1 but instead of having a behavior property on the AgentSession, we only have a StateBag property on the AgentSession.
Behaviors really make more sense to live with the agent rather than the Session, but state should live on the session.
When the AgentSession is used by the Agent, the Agent runs the behaviors against the Session, and the behavior stores it's state on the Session StateBag.
This means that users are unable to access the behavior from the AgentSession, e.g. via `AgentSession.GetService<TBehavior>()`.
However, the behaviors can be public properties on the Agent or can be retrieved from the agent via `AIAgent.GetService<MyAIContextProvider>()`.
```csharp
public class AgentSession
{
...
public AgentSessionStateBag StateBag { get; protected set; } = new();
...
}
```
### Option 3: Keep the current approach of custom Serialize/Deserialize methods
Decision Drivers satisfied: A and C
This option keeps the current approach of having custom Serialize/Deserialize methods on the AgentSession and AIAgent.
## Decision Outcome
Chosen option:
**Option 2** — separate state from behavior, with only state on the AgentSession — because it satisfies all decision drivers and provides the cleanest separation of concerns. Since not all AgentSession implementations have yet been cleanly separated from their behaviors, AIAgent.SerializeSession and AIAgent.DeserializeSession is kept for the time being, but most session types can be serialized and deserialized directly using JsonSerializer.
### Consequences
- Good, because providers are fully stateless — the same provider instance works correctly across any number of concurrent sessions without risk of state leakage.
- Good, because `AgentSession` can be serialized and deserialized with standard `System.Text.Json` mechanisms, satisfying decision driver B.
- Good, because the generic `StateBag` is extensible — new providers can store arbitrary state without requiring changes to the session class.
- Good, because users can access providers via the agent (e.g. `agent.GetService<InMemoryChatHistoryProvider>()`) satisfying decision driver C.
- Good, because sessions are always in a complete and valid state after deserialization — there is no "incomplete until first use" problem as in Option 1.
- Neutral, because providers cannot be accessed directly from the session; callers must go through the agent. This is a minor usability trade-off but keeps the session focused on state only.
- Bad, because each provider must be disciplined about using `ProviderSessionState<T>` and not storing session-specific data in instance fields. This is a correctness concern for custom provider implementers.
# Foundry agent surface stays centered on `ChatClientAgent`
## Context
The Microsoft Foundry integration exposes two distinct usage patterns:
1. Direct Responses usage, where callers provide model, instructions, and tools at runtime.
2. Server-side versioned agents, where callers create and manage `AgentVersion` resources through `AIProjectClient.Agents`.
We briefly explored adding public wrapper types such as `FoundryAgent`, `FoundryVersionedAgent`, and `FoundryResponsesChatClient` to make those paths feel more specialized. That direction created extra public types, duplicated existing `ChatClientAgent` behavior, and pushed samples toward compatibility helpers instead of the native Azure SDK flow.
## Decision
Keep the public surface centered on `ChatClientAgent`.
- Direct Responses scenarios use `AIProjectClient.AsAIAgent(...)`.
- Server-side versioned scenarios use native `AIProjectClient.Agents` APIs to create or retrieve agent resources, then wrap `AgentRecord` or `AgentVersion` with `AIProjectClient.AsAIAgent(...)`.
- Compatibility helpers such as `AIProjectClient.CreateAIAgentAsync(...)` and `AIProjectClient.GetAIAgentAsync(...)` remain only as obsolete migration shims.
- Public wrapper types `FoundryAgent`, `FoundryVersionedAgent`, `FoundryResponsesChatClient`, and `FoundryResponsesChatClientAgent` are not part of the chosen direction.
## Why
- `ChatClientAgent` is already the framework abstraction used everywhere else.
- `AIProjectClient` is the native Azure SDK entry point for versioned agent lifecycle operations.
- A single agent abstraction avoids parallel type hierarchies for the same backend.
- Samples become clearer when they show either:
- direct Responses construction via `AIProjectClient.AsAIAgent(...)`, or
- native Foundry resource management via `AIProjectClient.Agents`.
## Consequences
### Direct Responses path
Use the convenience overloads on `AIProjectClient`:
- `FoundryAgents/` samples show the direct Responses path with `AIProjectClient.AsAIAgent(...)`.
- `FoundryVersionedAgents/` samples should show native `AIProjectClient.Agents` create/get/delete flows plus `AsAIAgent(...)`.
### Compatibility APIs
Obsolete helper extensions remain only to ease migration of existing code. New samples and new guidance should not be written against them.
## Rejected direction
Do not introduce or preserve separate public wrapper types whose main purpose is to forward to `ChatClientAgent` while carrying Foundry-specific naming.
That approach:
- duplicates lifecycle concepts already present on `AIProjectClient`,
- fragments the public API,
- complicates samples and docs,
- and makes migration harder by encouraging wrapper-specific affordances.
The Agent Framework needs a skills system that lets agents discover and use domain-specific knowledge, reference documents, and executable scripts. Skills can originate from different sources — filesystem directories (SKILL.md files), inline C# code, or reusable class libraries — and the framework must support all three uniformly while allowing extensibility, composition, and filtering.
## Decision Drivers
- Skills must be definable from multiple sources: filesystem, inline code, reusable classes, etc
- Common abstractions are needed so the provider and builder work uniformly regardless of skill origin
- File-based scripts must support user-defined executors, enabling custom runtimes and languages; code/class-based scripts execute in-process as C# delegates
- Skills must be filterable so consumers can include or exclude specific skills based on defined criteria
- Multiple skill sources must be composable into a single provider
- It must be possible to add custom skill sources (e.g., databases, REST APIs, package registries) by implementing a common abstraction
## Architecture
### Model-Facing Tools
Skills are presented to the model as up to three tools that progressively disclose skill content. The system prompt lists available skill names and descriptions; the model then calls these tools on demand:
- **`load_skill(skillName)`** — returns the full skill body (instructions, listed resources, listed scripts)
- **`read_skill_resource(skillName, resourceName)`** — reads a supplementary resource (file-based or code-defined) associated with a skill
- **`run_skill_script(skillName, scriptName, arguments?)`** — executes a script associated with a skill; only registered when at least one skill contains scripts
Each tool delegates to the corresponding method on the resolved `AgentSkill` — calling `Resource.ReadAsync()` or `Script.RunAsync()` respectively.
If skills have no scripts defined, the `run_skill_script` tool is **not advertised** to the model and instructions related to script execution are **not included** in the default skills instructions.
### Abstract Base Types
The architecture defines four abstract base types that all skill variants implement:
```csharp
public abstract class AgentSkill
{
public abstract AgentSkillFrontmatter Frontmatter { get; }
public abstract string Content { get; }
public abstract IReadOnlyList<AgentSkillResource>? Resources { get; }
public abstract IReadOnlyList<AgentSkillScript>? Scripts { get; }
1. **File-Based Skills** — discovered from `SKILL.md` files on the filesystem. Resources and scripts are files in subdirectories.
2. **Programmatic Skills** — defined in C# code. These are further divided into:
- **Inline Skills** — built at runtime via the `AgentInlineSkill` class and its fluent API. Ideal for quick, agent-specific skill definitions.
- **Class-Based Skills** — defined as reusable C# classes that subclass `AgentClassSkill`. Ideal for packaging skills as shared libraries or NuGet packages.
Both programmatic skill types use `AgentInlineSkillResource` and `AgentInlineSkillScript` for their resources and scripts. They are typically served by `AgentInMemorySkillsSource`, which accepts any `AgentSkill` and is not limited to programmatic skills.
### File-Based Skills
File-based skills are authored as `SKILL.md` files on disk. Resources and scripts are discovered from corresponding subfolders within the skill directory.
**`AgentFileSkill`** — A filesystem-based skill discovered from a directory containing a `SKILL.md` file. Parsed from YAML frontmatter; content is the raw markdown body. Resources and scripts are discovered from files in corresponding subfolders:
**`AgentFileSkillScript`** — A file-based skill script that represents a script file on disk. Delegates execution to an external `AgentFileSkillScriptRunner` callback (e.g., runs Python/shell via `Process.Start`). Throws `NotSupportedException` if no executor is configured:
```csharp
public delegate Task<object?> AgentFileSkillScriptRunner(
The executor can be provided at the **provider level** via `AgentSkillsProviderBuilder.UseFileScriptRunner(executor)` and optionally overridden for a **particular file skill** or for a **set of skills** at the file skill source level, giving fine-grained control over how different scripts are executed.
**`AgentFileSkillsSource`** — A skill source that discovers skills from filesystem directories containing `SKILL.md` files. Recursively scans directories (max 2 levels), validates frontmatter, and enforces path traversal and symlink security checks:
```csharp
public sealed partial class AgentFileSkillsSource : AgentSkillsSource
{
public AgentFileSkillsSource(
IEnumerable<string> skillPaths,
AgentFileSkillScriptRunner scriptRunner,
AgentFileSkillsSourceOptions? options = null,
ILoggerFactory? loggerFactory = null) { ... }
}
```
**`AgentFileSkillsSourceOptions`** — Configuration options for `AgentFileSkillsSource`. Allows customizing the allowed file extensions for resources and scripts without adding constructor parameters:
```csharp
public sealed class AgentFileSkillsSourceOptions
{
public IEnumerable<string>? AllowedResourceExtensions { get; set; }
public IEnumerable<string>? AllowedScriptExtensions { get; set; }
}
```
**Example** — A file-based skill on disk and how it is added to a source:
```
skills/
└── unit-converter/
├── SKILL.md # frontmatter + instructions
├── resources/
│ └── conversion-table.csv # discovered as a resource
└── scripts/
└── convert.py # discovered as a script
```
```csharp
var source = new AgentFileSkillsSource(skillPaths: ["./skills"], scriptRunner: SubprocessScriptRunner.RunAsync);
Programmatic skills are defined in C# code rather than discovered from the filesystem. There are two kinds: **inline** and **class-based**. Both use `AgentInlineSkillResource` and `AgentInlineSkillScript` for resources and scripts, and are held by a single `AgentInMemorySkillsSource`.
**`AgentInMemorySkillsSource`** — A general-purpose skill source that holds any `AgentSkill` instances in memory. Although commonly used for programmatic skills (`AgentInlineSkill` and `AgentClassSkill`), it accepts any `AgentSkill` subclass and is not restricted to code-defined skills:
```csharp
public sealed class AgentInMemorySkillsSource : AgentSkillsSource
{
public AgentInMemorySkillsSource(
IEnumerable<AgentSkill> skills,
ILoggerFactory? loggerFactory = null) { ... }
}
```
#### Inline Skills
Inline skills are built at runtime via the `AgentInlineSkill` class and its fluent API. They are ideal for quick, agent-specific skill definitions where a full class hierarchy would be overkill.
**`AgentInlineSkill`** — A skill defined entirely in code. Resources can be static values or functions; scripts are always functions. Constructed with name, description, and instructions, then extended with resources and scripts:
**`AgentInlineSkillResource`** — A skill resource backed by a delegate. The delegate is invoked via an `AIFunction` each time `ReadAsync` is called, producing a dynamic (computed) value:
```csharp
public sealed class AgentInlineSkillResource : AgentSkillResource
{
public AgentInlineSkillResource(Delegate handler, string name, string? description = null)
=> JsonSerializer.Serialize(new { result = Math.Round(value * factor, 4) });
```
#### Class-Based Skills
Class-based skills are designed for packaging skills as reusable libraries. Users subclass `AgentClassSkill` and override properties. Unlike inline skills, class-based skills are self-contained, can live in shared libraries or NuGet packages, and are well-suited for dependency injection.
**`AgentClassSkill`** — An abstract base class for defining skills as reusable C# classes that bundle all skill components (frontmatter, instructions, resources, scripts) together. Designed for packaging skills as distributable libraries:
```csharp
public abstract class AgentClassSkill : AgentSkill
{
public abstract string Instructions { get; }
// Content is auto-synthesized from Frontmatter + Instructions + Resources + Scripts
The following subsections present alternative approaches for handling filtering, caching, and deduplication of skills across multiple sources.
### Via Composition
In this approach, the `AgentSkillsProvider` accepts a **single**`AgentSkillsSource`. Multiple sources are composed externally via an aggregate source, and cross-cutting concerns like filtering, caching, and deduplication are implemented as **source decorators** — subclasses of `DelegatingAgentSkillsSource` that intercept `GetSkillsAsync()`.
**`FilteringAgentSkillsSource`** — A decorator that applies filter logic before returning results. The decorator pattern keeps filtering orthogonal to source implementations and allows composing multiple filters:
```csharp
public sealed class FilteringAgentSkillsSource : DelegatingAgentSkillsSource
public FilteringAgentSkillsSource(AgentSkillsSource innerSource, Func<AgentSkill, bool> predicate)
: base(innerSource)
{
_predicate = predicate;
}
public override async Task<IList<AgentSkill>> GetSkillsAsync(CancellationToken cancellationToken = default)
{
var skills = await this.InnerSource.GetSkillsAsync(cancellationToken);
return skills.Where(_predicate).ToList();
}
}
```
**`CachingAgentSkillsSource`** — A decorator that caches skills after the first load, keeping the provider stateless and giving consumers control over caching granularity per source. For example, file-based skills (expensive to discover) can be cached while code-defined skills remain uncached:
```csharp
public sealed class CachingAgentSkillsSource : DelegatingAgentSkillsSource
{
private IList<AgentSkill>? _cached;
public CachingAgentSkillsSource(AgentSkillsSource innerSource)
: base(innerSource)
{
}
public override async Task<IList<AgentSkill>> GetSkillsAsync(CancellationToken cancellationToken = default)
**Deduplication** is similarly implemented as a decorator (`DeduplicatingAgentSkillsSource`) that deduplicates by name (case-insensitive, first-one-wins) and logs a warning for skipped duplicates.
**Example** — Combining file-based and code-defined sources with filtering and caching:
```csharp
var fileSource = new CachingAgentSkillsSource(new AgentFileSkillsSource(["./skills"]));
var codeSource = new AgentInMemorySkillsSource([myCodeSkill]);
var compositeSource = new FilteringAgentSkillsSource(
new AggregatingAgentSkillsSource([fileSource, codeSource]),
filter: s => s.Frontmatter.Name != "internal");
var provider = new AgentSkillsProvider(compositeSource);
- Clean single-responsibility: the provider serves skills, sources provide them.
- Caching, filtering, and deduplication are composable as source decorators — each concern is a separate, testable wrapper.
**Cons:**
- DI is less flexible: multiple `AgentSkillsSource` implementations registered in the container cannot be auto-injected into the provider. The consumer must manually compose them via an aggregate source.
- Increased public API surface: requires additional public classes (aggregate source, caching decorators, filtering decorators) that consumers need to learn and use.
### Via AgentSkillsProvider
In this approach, the `AgentSkillsProvider` accepts **`IEnumerable<AgentSkillsSource>`** and handles aggregation, filtering, caching, and deduplication internally.
The provider aggregates skills from all registered sources, deduplicates by name (case-insensitive, first-one-wins), caches the result after the first load, and optionally applies filtering via a predicate on `AgentSkillsProviderOptions`. Duplicate skill names are logged as warnings.
**Example** — Registering multiple sources directly with the provider:
```csharp
// Conceptual example — in practice, use AgentSkillsProviderBuilder
var fileSource = new AgentFileSkillsSource(["./skills"]);
var codeSource = new AgentInMemorySkillsSource([myCodeSkill]);
- DI-friendly: register multiple `AgentSkillsSource` implementations in the container, and they are all auto-injected into `AgentSkillsProvider` via `IEnumerable<AgentSkillsSource>`.
- Smaller public API surface: no need for aggregate source, caching decorators, or filtering decorator classes — these concerns are handled internally by the provider.
**Cons:**
- The provider takes on multiple responsibilities — aggregation, caching, deduplication, and filtering.
- Less granular caching control: caching is all-or-nothing across sources rather than per-source as with decorators.
- Less extensible: new behaviors (e.g., ordering, TTL expiration) require modifying the provider rather than adding a decorator.
### Builder Pattern
**`AgentSkillsProviderBuilder`** provides a fluent API for composing skills from multiple sources. The builder centralizes configuration — script executors, approval callbacks, prompt templates, and filtering — so consumers don't need to know the underlying source types.
The builder internally decides how to wire up the object graph: it creates the appropriate source instances, applies caching and filtering, and returns a fully configured `AgentSkillsProvider`. This keeps the setup code concise while still allowing fine-grained control when needed.
**Example** — Using the builder to combine multiple source types with configuration:
- **Explicit skill context at execution time.**`RunAsync` receives the owning `AgentSkill`, so any script can access skill metadata or resources during execution without requiring construction-time wiring.
- **Self-contained abstraction.** A dedicated type communicates clearly that scripts are a skills-framework concept, separate from general-purpose AI functions.
- **Easier extensibility for custom script types.** Third-party implementations can subclass `AgentSkillScript` and access the owning skill in `RunAsync` without special setup.
**Cons:**
- **Wrapper overhead.**`AgentInlineSkillScript` is a thin pass-through around `AIFunction` — it adds a class, a constructor, and an indirection layer for no behavioral difference.
- **Parallel abstraction.**`AgentSkillScript` and `AIFunction` serve overlapping purposes (named callable with arguments), creating two parallel hierarchies for the same concept.
- **Friction for consumers.** Users who already have `AIFunction` instances must wrap them in `AgentInlineSkillScript` to use them as scripts, adding ceremony.
### Option B — Reuse `AIFunction` directly
Scripts are represented as `AIFunction` (from `Microsoft.Extensions.AI`). `AgentSkill.Scripts` returns
`IReadOnlyList<AIFunction>?`. `AgentInlineSkillScript` is eliminated entirely — callers use
`AIFunctionFactory.Create(delegate, name: ...)` or pass `AIFunction` instances directly.
`AgentFileSkillScript` becomes an `AIFunction` subclass that captures its owning `AgentFileSkill` via
an internal back-reference set during construction.
```csharp
// AgentSkill exposes scripts as AIFunction directly:
public abstract IReadOnlyList<AIFunction>? Scripts { get; }
// Inline scripts use AIFunctionFactory — no wrapper class needed
var skill = new AgentInlineSkill("my-skill", "desc", "instructions");
- **Fewer types.** Eliminates `AgentSkillScript` and `AgentInlineSkillScript`, reducing the public API surface by two classes.
- **Seamless interop.** Any `AIFunction` — whether from `AIFunctionFactory`, a custom subclass, or an external library — can be used as a skill script with zero wrapping.
- **Consistent with `Microsoft.Extensions.AI` ecosystem.** Scripts share the same type as tool functions used by `IChatClient` and `FunctionInvokingChatClient`, reducing conceptual overhead for developers already familiar with the ecosystem.
**Cons:**
- **No owning-skill context in invocation signature.**`AIFunction.InvokeAsync` does not accept an `AgentSkill` parameter, so `AgentFileSkillScript` must capture its owning skill via an internal setter during construction. This adds a construction-order dependency: the skill must set the back-reference on its scripts.
- **Custom script types lose automatic skill access.** Third-party `AIFunction` subclasses that need the owning skill must implement their own mechanism (e.g., constructor injection, closure capture) instead of receiving it as a method parameter.
- **Semantic overloading.**`AIFunction` now means both "a tool the model can call" and "a script within a skill", which could blur the distinction for framework users.
## Resource Representation: `AgentSkillResource` vs `AIFunction`
Two approaches were considered for representing skill resources (supplementary content such as references, assets, or dynamic data):
### Option A — Custom `AgentSkillResource` abstract base class (original design)
Resources are modeled as a custom `AgentSkillResource` abstract class with `Name`, `Description`, and
- **Clear semantic distinction.** A dedicated `AgentSkillResource` type distinguishes resources (data providers) from scripts (executable actions), making the API self-documenting.
- **Purpose-built API.**`ReadAsync` communicates intent better than `InvokeAsync` for a data-access operation.
**Cons:**
- **Wrapper overhead.**`AgentInlineSkillResource` wraps `AIFunction` internally for delegate/function cases — adding a class and indirection for no behavioral difference.
- **Parallel abstraction.**`AgentSkillResource` and `AIFunction` serve overlapping purposes (named callable that returns data), creating two parallel hierarchies.
- **Friction for consumers.** Users who already have `AIFunction` instances must wrap them in `AgentInlineSkillResource`, adding ceremony.
### Option B — Reuse `AIFunction` directly
Resources are represented as `AIFunction`. `AgentSkill.Resources` returns `IReadOnlyList<AIFunction>?`.
`AgentInlineSkillResource` becomes an `AIFunction` subclass (retained as a convenience for the static-value
pattern: `new AgentInlineSkillResource("data", "name")`). `AgentFileSkillResource` becomes an `AIFunction`
subclass that reads file content.
```csharp
// AgentSkill exposes resources as AIFunction directly:
public abstract IReadOnlyList<AIFunction>? Resources { get; }
// Static resource — AgentInlineSkillResource is retained as a convenience AIFunction subclass
var resource = new AgentInlineSkillResource("static content", "my-resource");
// Dynamic resource — AgentInlineSkillResource wraps delegate as AIFunction
var resource = new AgentInlineSkillResource((IServiceProvider sp) => GetData(sp), "my-resource");
// Pre-built AIFunction can be used directly — no wrapping needed
skill.AddResource(myAIFunction);
// Class-based skill declares resources as:
public override IReadOnlyList<AIFunction>? Resources { get; } =
[
new AgentInlineSkillResource("# Conversion Tables\n...", "conversion-table"),
];
// Provider reads resources via standard AIFunction invocation:
- **Fewer base types.** Eliminates the `AgentSkillResource` abstract class, reducing the public API surface.
- **Seamless interop.** Any `AIFunction` can be used as a skill resource with zero wrapping.
**Cons:**
- **Loss of semantic distinction.** Resources and scripts are now both `AIFunction`, which could make it less obvious which list a function belongs to when reading code.
- **Static values require a wrapper.** Unlike the original `ReadAsync` which could return a stored value directly, `AIFunction.InvokeAsync` implies invocation. `AgentInlineSkillResource` is retained as a convenience subclass to handle the static-value case, so this is not eliminated — just moved to a different class.
## Decision Outcome
### 1. Keep `AgentSkillResource` and `AgentSkillScript` (Option A for both sections)
We are staying with the custom `AgentSkillResource` and `AgentSkillScript` model classes instead of reusing `AIFunction`:
- **Resources have no parameters.** If a consumer provides an `AIFunction` with parameters, those parameters will never be advertised to the LLM, and the resulting call will fail.
- **Approval breaks for `AIFunction`-based representations.** When a resource or script represented by an `AIFunction` is configured with approval, the second approval invocation will not work correctly.
- **Injecting the owning skill into an `AIFunction`-based script is problematic.** Constructor injection would introduce a circular reference between the skill and the script. An internal property setter is possible but adds coupling.
### 2. Make all agent skill classes internal
All agent-skill-related classes are made `internal` to minimize the public API surface while the feature matures. We can reconsider and promote types to `public` later based on community signal.
This leaves two public entry points:
- **`AgentSkillsProvider`** — use directly when all skills come from a single source and filtering is not needed.
- **`AgentSkillsProviderBuilder`** — use when mixing skill types or when filtering support is required.
### 3. Caching at provider level
Caching of tools and instructions is implemented inside `AgentSkillsProvider` rather than as an external decorator. Recreating tools and instructions on every provider call is wasteful, and a caching decorator sitting outside the provider would not have the information needed to cache them effectively.
The `agent-framework-core` package currently bundles OpenAI and Azure OpenAI client implementations along with their dependencies (`openai`, `azure-identity`, `azure-ai-projects`, `packaging`). This makes core heavier than necessary for users who don't use OpenAI, and it conflates the core abstractions with a specific provider implementation. Additionally, the current class naming (`OpenAIResponsesClient`, `OpenAIChatClient`) is based on the underlying OpenAI API names rather than what users actually want to do, making discoverability harder for newcomers.
## Decision Drivers
- **Lightweight core**: Core should only contain abstractions, middleware infrastructure, and telemetry — no provider-specific code or dependencies.
- **Discoverability-first**: Import namespaces should guide users to the right client. `from agent_framework.openai import ...` should surface all OpenAI-related clients; `from agent_framework.azure import ...` should surface Foundry, Azure AI, and other Azure-specific classes.
- **Provider-leading naming**: The primary client name should reflect the provider, not the underlying API. The Responses API is now the recommended default for OpenAI, so its client should be called `OpenAIChatClient` (not `OpenAIResponsesClient`).
- **Clean separation of concerns**: Azure-specific deprecated wrappers belong in the azure-ai package, not in the OpenAI package.
## Considered Options
- **Keep OpenAI in core**: Simpler but keeps core heavy; doesn't help discoverability.
- **Extract OpenAI with Azure wrappers in the OpenAI package**: Keeps Azure OpenAI wrappers alongside OpenAI code, but pollutes the OpenAI package with Azure concerns.
- **Extract OpenAI, place Azure wrappers in azure-ai**: Clean separation; the OpenAI package has zero Azure dependencies; deprecated Azure wrappers live in a single file in azure-ai for easy future deletion.
## Decision Outcome
Chosen option: "Extract OpenAI, place Azure wrappers in azure-ai", because it achieves the lightest core, cleanest OpenAI package, and the most maintainable deprecation path.
Key changes:
1. **New `agent-framework-openai` package** with dependencies on `agent-framework-core`, `openai`, and `packaging` only.
2. **Class renames**: `OpenAIResponsesClient` → `OpenAIChatClient` (Responses API), `OpenAIChatClient` → `OpenAIChatCompletionClient` (Chat Completions API). Old names remain as deprecated aliases.
3. **Deprecated classes**: `OpenAIAssistantsClient`, all `AzureOpenAI*Client` classes, `AzureAIClient`, `AzureAIAgentClient`, and `AzureAIProjectAgentProvider` are marked deprecated.
4. **New `FoundryChatClient`** in azure-ai for Azure AI Foundry Responses API access, built on `RawFoundryChatClient(RawOpenAIChatClient)`.
5. **All deprecated `AzureOpenAI*` classes** consolidated into a single file (`_deprecated_azure_openai.py`) in the azure-ai package for clean future deletion.
6. **Core's `agent_framework.openai` and `agent_framework.azure` namespaces** become lazy-loading gateways, preserving backward-compatible import paths while removing hard dependencies.
7. **Unified `model` parameter** replaces `model_id` (OpenAI), `deployment_name` (Azure OpenAI), and `model_deployment_name` (Azure AI) across all client constructors. The term `model` is intentionally generic: it naturally maps to an OpenAI model name *and* to an Azure OpenAI deployment name, making it straightforward to use `OpenAIChatClient` with either OpenAI or Azure OpenAI backends (via `AsyncAzureOpenAI`). Environment variables are similarly unified (e.g., `OPENAI_MODEL` instead of separate `OPENAI_CHAT_MODEL_ID` / `OPENAI_CHAT_COMPLETION_MODEL_ID`).
8. **`FoundryAgent`** replaces the pattern of `Agent(client=AzureAIClient(...))` for connecting to pre-configured agents in Azure AI Foundry (PromptAgents and HostedAgents). The underlying `RawFoundryAgentChatClient` is an implementation detail — most users interact only with `FoundryAgent`. `AzureAIAgentClient` is separately deprecated as it refers to the V1 Agents Service API. See below for design rationale.
### Foundry Agent Design: `FoundryAgentClient` vs `FoundryAgent`
The existing `AzureAIClient` combines two concerns: CRUD lifecycle management (creating/deleting agents on the service) and runtime communication (sending messages via the Responses API). The new design removes CRUD entirely — users connect to agents that already exist in Foundry.
**Two approaches were considered:**
**Option A — `FoundryAgentClient` only (public ChatClient):**
Users compose `Agent(client=FoundryAgentClient(...), tools=[...])`. This follows the universal `Agent(client=X)` pattern used by every other provider. However, a "client" that wraps a named remote agent (with `agent_name` as a constructor param) is semantically odd — clients typically wrap a model endpoint, not a specific agent.
**Option B — `FoundryAgent` (Agent subclass) + private `_FoundryAgentChatClient` and public `RawFoundryAgentChatClient`:**
Users write `FoundryAgent(agent_name="my-agent", ...)` for the common case. Internally, `FoundryAgent` creates a `_FoundryAgentChatClient` and passes it to the standard `Agent` base class. For advanced customization, users pass `client_type=RawFoundryAgentChatClient` (or a custom subclass) to control the client middleware layers. The `Agent(client=RawFoundryAgentChatClient(...))` composition pattern still works for users who prefer it.
**Chosen option: Option B**, because:
- The common case (`FoundryAgent(...)`) is a single object with no boilerplate.
- `client_type=` gives full control over client middleware without parameter duplication — the agent forwards connection params to the client internally.
- `RawFoundryAgent(RawAgent)` and `FoundryAgent(Agent)` mirror the established `RawAgent`/`Agent` pattern.
- Runtime validation (only `FunctionTool` allowed) lives in `RawFoundryAgentChatClient._prepare_options`, ensuring it applies regardless of how the client is used — through `FoundryAgent`, `Agent(client=...)`, or any custom composition.
**Public classes:**
- `RawFoundryAgentChatClient(RawOpenAIChatClient)` — Responses API client that injects agent reference and validates tools. Extension point for custom client middleware.
- `RawFoundryAgent(RawAgent)` — Agent without agent-level middleware/telemetry.
- `FoundryAgent(AgentTelemetryLayer, AgentMiddlewareLayer, RawFoundryAgent)` — Recommended production agent.
**Internal (private):**
- `_FoundryAgentChatClient` — Full client with function invocation, chat middleware, and telemetry layers. Created automatically by `FoundryAgent`; users customize via `client_type=RawFoundryAgentChatClient` or a custom subclass.
**Deprecated:**
- `AzureAIClient` — replaced by `FoundryAgent` (which uses `FoundryAgentClient` internally).
- `AzureAIAgentClient` — refers to V1 Agents Service API, no direct replacement.
- `AzureAIProjectAgentProvider` — replaced by `FoundryAgent`.
When using `ChatClientAgent` with tools, the `FunctionInvokingChatClient` (FIC) loops multiple times — service call → tool execution → service call → … — before producing a final response. There are two points of discrepancy between how chat history is stored by the framework's `ChatHistoryProvider` and how the underlying AI service stores chat history (e.g., OpenAI Responses with `store=true`):
1. **Persistence timing**: The AI service persists messages after *each* service call within the FIC loop. The `ChatHistoryProvider` currently persists messages only once, at the *end* of the full agent run (after all FIC loop iterations complete).
2. **Trailing `FunctionResultContent` storage**: When tool calling is terminated mid-loop (e.g., via `FunctionInvokingChatClient` termination filters), the final response from the agent may contain `FunctionResultContent` that was never sent to a subsequent service call. The AI service never stores this trailing `FunctionResultContent`, but the `ChatHistoryProvider` currently stores all response content, including the trailing `FunctionResultContent`.
These discrepancies mean that a `ChatHistoryProvider`-managed conversation and a service-managed conversation can diverge in content and structure, even when processing the same interactions.
### Practical Impact: Resuming After Tool-Call Termination
Today, users of `AIAgent` get different behaviors depending on whether chat history is stored service-side or in a `ChatHistoryProvider`. This creates concrete challenges — for example, when the function call loop is terminated and the user wants to resume the conversation in a subsequent run. With service-stored history, the trailing `FunctionResultContent` is never persisted, so the last stored message is the `FunctionCallContent` from the service. With `ChatHistoryProvider`-stored history, the trailing `FunctionResultContent`*is* persisted. The user cannot know whether the last `FunctionResultContent` is in the chat history or not without inspecting the storage mechanism, making it difficult to write resumption logic that works correctly regardless of the storage backend.
### Relationship Between the Two Discrepancies
The persistence timing and `FunctionResultContent` trimming behaviors are interrelated:
- **Per-service-call persistence**: When messages are persisted after each individual service call, trailing `FunctionResultContent` trimming is unnecessary. If tool calling is terminated, the `FunctionResultContent` from the terminated call was never sent to a subsequent service call, so it is never persisted. The per-service-call approach naturally matches the service's behavior.
- **Per-run persistence**: When messages are batched and persisted at the end of the full run, trailing `FunctionResultContent` trimming becomes necessary to match the service's behavior. Without trimming, the stored history contains `FunctionResultContent` that the service would never have stored.
## Decision Drivers
- **A. Consistency**: The default behavior of `ChatHistoryProvider` should produce stored history that closely matches what the underlying AI service would store, minimizing surprise when switching between framework-managed and service-managed chat history.
- **B. Atomicity**: A run that fails mid-way through a multi-step tool-calling loop should not leave chat history in a partially-updated state, unless the user explicitly opts into that behavior.
- **C. Recoverability**: For long-running tool-calling loops, it should be possible to recover intermediate progress if the process is interrupted, rather than losing all work from the current run.
- **D. Simplicity**: The default behavior should be easy to understand and predict for most users, without requiring knowledge of the FIC loop internals.
- **E. Flexibility**: Regardless of the chosen default, users should be able to opt into the alternative behavior.
## Considered Options
- Option 1: Per-run persistence with opt-in FRC (FunctionResultContent) trimming
### Option 1: Per-run persistence with opt-in FRC trimming
Keep the current default behavior of persisting chat history only at the end of the full agent run. Add `FunctionResultContent` trimming as an opt-in behavior to improve consistency with service storage.
- Good, because runs are atomic — chat history is only updated when the full run succeeds, satisfying driver B.
- Good, because the mental model is simple: one run = one history update, satisfying driver D.
- Good, because trimming trailing `FunctionResultContent` improves consistency with service storage, partially satisfying driver A.
- Bad, because the default persistence timing still differs from the service's behavior (per-run vs. per-service-call), only partially satisfying driver A.
- Bad, because if the process crashes mid-loop, all intermediate progress from the current run is lost, not satisfying driver C.
- Bad, because this option alone does not provide a way for users to opt into per-service-call persistence, not satisfying driver E.
Introduce an optional RequirePerServiceCallChatHistoryPersistence setting to persist chat history after each individual service call within the FIC loop, matching the AI service's behavior. Trailing `FunctionResultContent` trimming is unnecessary with this approach (it is naturally handled).
- Good, because the stored history matches the service's behavior when opting in for both timing and content, fully satisfying driver A.
- Good, because intermediate progress is preserved if the process is interrupted, satisfying driver C.
- Good, because no separate `FunctionResultContent` trimming logic is needed, reducing complexity.
- Bad, because chat history may be left in an incomplete state if the run fails mid-loop (e.g., `FunctionCallContent` stored without corresponding `FunctionResultContent`), not satisfying driver B. A subsequent run cannot proceed without manually providing the missing `FunctionResultContent`.
- Bad, because the mental model is more complex: a single run may produce multiple history updates, partially failing driver D.
- Neutral, because users can opt out to per-run persistence if they prefer atomicity, satisfying driver E.
## Decision Outcome
Chosen option: **Option 2: Opt-in per-service-call persistence (via `RequirePerServiceCallChatHistoryPersistence`)**. The existing per-run persistence behavior is retained as-is, requiring no changes from users. Per-service-call persistence is available as an opt-in feature via the `RequirePerServiceCallChatHistoryPersistence` setting. This satisfies drivers B (atomicity) and D (simplicity) for the common case, while fully satisfying driver A (consistency) for users who opt into simulated service-stored behavior. Users who need per-service-call persistence for recoverability (driver C) can enable it explicitly.
### Configuration Matrix
The behavior depends on the combination of `UseProvidedChatClientAsIs` and `RequirePerServiceCallChatHistoryPersistence`:
| `false` (default) | `false` (default) | **Per-run persistence.** Messages are persisted at the end of the full agent run via the `ChatHistoryProvider`. |
| `false` | `true` | **Per-service-call persistence (simulated).** A `PerServiceCallChatHistoryPersistingChatClient` middleware is automatically injected into the chat client pipeline between `FunctionInvokingChatClient` and the leaf `IChatClient`. Messages are persisted after each service call. A sentinel `ConversationId` causes FIC to treat the conversation as service-managed. |
| `true` | `false` | **Per-run persistence.** No middleware is injected because the user has provided a custom chat client stack. Messages are persisted at the end of the run. |
| `true` | `true` | **User responsibility.** The system checks whether the custom chat client stack includes a `PerServiceCallChatHistoryPersistingChatClient`. If not, a warning is emitted — the user is expected to have added their own per-service-call persistence mechanism. End-of-run persistence is skipped. |
### Consequences
- Good, because per-run persistence is atomic by default — chat history is only updated when the full run succeeds, satisfying driver B.
- Good, because the default mental model is simple: one run = one history update, satisfying driver D.
- Good, because users who opt into `RequirePerServiceCallChatHistoryPersistence` get stored history that matches the service's behavior for both timing and content, fully satisfying driver A.
- Good, because per-service-call persistence preserves intermediate progress if the process is interrupted, satisfying driver C when opted in.
- Good, because no separate `FunctionResultContent` trimming logic is needed when per-service-call persistence is active — it is naturally handled.
- Good, because conflict detection (configurable via `ThrowOnChatHistoryProviderConflict`, `WarnOnChatHistoryProviderConflict`, `ClearOnChatHistoryProviderConflict`) prevents misconfiguration when a service returns a `ConversationId` alongside a configured `ChatHistoryProvider`.
- Bad, because per-service-call persistence (when opted in) may leave chat history in an incomplete state if the run fails mid-loop (e.g., `FunctionCallContent` stored without corresponding `FunctionResultContent`), requiring manual recovery in rare cases.
- Neutral, because users who want per-service-call consistency can opt in via `RequirePerServiceCallChatHistoryPersistence = true`, satisfying driver E.
- Neutral, because increased write frequency from per-service-call persistence may impact performance for some storage backends; this can be mitigated with a caching decorator.
### Implementation Notes
#### Conversation ID Consistency
When `RequirePerServiceCallChatHistoryPersistence` is enabled, the `PerServiceCallChatHistoryPersistingChatClient`
decorator also updates `session.ConversationId` after each service call. This handles two scenarios:
1. **Framework-managed chat history** — the decorator sets a sentinel `ConversationId` on the response
so that `FunctionInvokingChatClient` treats the conversation as service-managed (clearing accumulated
history between iterations and not injecting duplicate `FunctionCallContent` during approval processing).
2. **Service-stored chat history** — when the service returns a real `ConversationId`, the decorator
updates `session.ConversationId` immediately after each service call, rather than deferring the update
to the end of the run. This ensures intermediate ConversationId changes are captured even if the
process is interrupted mid-loop.
For some service-stored scenarios (e.g., the Conversations API with the Responses API), there is only
one thread with one ID, so every service call returns the same ConversationId and this per-call update
makes no practical difference. Enabling `RequirePerServiceCallChatHistoryPersistence` ensures consistent
per-service-call behavior across all service types regardless of how they manage ConversationIds.

# Agent Evaluation Architecture with Azure AI Foundry Integration
## Context and Problem Statement
Azure AI Foundry provides a rich evaluation service for AI agents — built-in evaluators for agent behavior (task adherence, intent resolution), tool usage (tool call accuracy, tool selection), quality (coherence, fluency, relevance), and safety (violence, self-harm, prohibited actions). Results are viewable in the Foundry portal with dashboards and comparison views.
However, using Foundry Evals with an agent-framework agent today requires significant manual effort. Developers must:
1. Transform agent-framework's `Message`/`Content` types into the OpenAI-style agent message schema that Foundry evaluators expect
2. Map tool definitions from agent-framework's `FunctionTool` format to evaluator-compatible schemas
3. Manually wire up the correct Foundry data source type (`azure_ai_traces`, `jsonl`, `azure_ai_target_completions`, etc.) depending on their scenario
4. Handle App Insights trace ID queries, response ID collection, and eval polling
Additionally, evaluation is a concern that extends beyond any single provider. Developers may want to use local evaluators (LLM-as-judge, regex, keyword matching), third-party evaluation libraries, or multiple providers in combination. The architecture must support this without creating a Foundry-specific lock-in at the API level.
### Functional Requirements for Agent Evaluation
- **Single agents and workflows.** Evaluate both individual agent responses and multi-agent workflow results, with per-agent breakdown to pinpoint underperformance.
- **One-shot and multi-turn conversations.** Capture full conversation trajectories — including tool calls and results — not just final query/response pairs.
- **Conversation factoring.** Support splitting conversations into query/response in multiple ways (last turn, full trajectory, per-turn) because different factorings measure different things.
- **Multiple providers, mix and match.** Run Foundry LLM-as-judge evaluators alongside fast local checks and custom evaluators on the same data, without restructuring code.
- **Third-party extensibility.** Any evaluation library can participate by implementing the `Evaluator` protocol (Python) or `IAgentEvaluator` interface (.NET). No predetermined list of supported libraries — the protocol is intentionally simple (`evaluate(items) → results`) so that wrappers for libraries like DeepEval, RAGAS, or Promptfoo are straightforward to write.
- **Bring your own evaluator.** Creating a custom evaluator should be as simple as writing a function.
- **Evaluate without re-running.** Evaluate existing responses from logs or previous runs without invoking the agent again.
## Decision Drivers
- **Zero-friction evaluation**: Developers should go from "I have an agent" to "I have eval results" with minimal code.
- **Provider-agnostic API**: Core evaluation capabilities must not be tied to any specific provider. Provider configuration should be separate from the evaluation call.
- **Lowest concept count**: Introduce the fewest possible new types, abstractions, and APIs for developers to learn.
- **Leverage existing knowledge**: The framework already knows which agents exist, what tools they have, and what conversations occurred. Evals should use this automatically rather than requiring the developer to re-specify it.
- **Foundry-native results**: When using Foundry, results should be viewable in the Foundry portal with dashboards and comparison views.
- **Progressive disclosure**: Simple scenarios should be near-zero code. Advanced scenarios should build on the same primitives.
- **Cross-language parity**: Design must be implementable in both Python and .NET.
## Considered Options
1. **Provider-specific functions** — Build Foundry-specific helper functions (`evaluate_agent()`, etc.) directly in the Azure package. All eval functions take Foundry connection parameters.
2. **Evaluator protocol with shared orchestration** — Define a provider-agnostic `Evaluator` protocol in the base agent library (`agent_framework` in Python, `Microsoft.Agents.AI` in .NET). Orchestration functions live alongside it. Providers implement the protocol.
3. **Full eval framework** — Build comprehensive eval infrastructure including custom evaluator definitions, scoring profiles, and reporting inside agent-framework.
## Decision Outcome
Proposed option: "Evaluator protocol with shared orchestration", because it delivers the low-friction developer experience, supports multiple providers without API changes, and keeps the concept count low.
### Usage Examples
#### Evaluate an agent
The agent is invoked once per query by default. For statistically meaningful evaluation, provide multiple diverse queries. For measuring **consistency** (does the same query produce reliable results?), use `num_repetitions` to run each query N times independently:
Each `AgentResponse` already contains the conversation (query + response), so the evaluator extracts query/response from the conversation. When you pass `responses` without `queries`, the conversation is the source of truth.
#### Evaluate with conversation split strategies
By default, evaluators see only the last turn (final user message → final assistant response). For multi-turn conversations, you can control how the conversation is factored for evaluation:
`@evaluator` uses **parameter name injection** — the function's parameter names determine what data it receives from the `EvalItem`. Supported names: `query`, `response`, `expected`, `expected_tool_calls`, `conversation`, `tools`, `context`. Any combination is valid.
query: str # property — derived from conversation split
response: str # property — derived from conversation split
```
`conversation` is the single source of truth. `query` and `response` are derived properties — splitting the conversation at the last user message (default) and extracting text from each side. Changing the `split_strategy` consistently changes all derived values.
`tools` provides typed `FunctionTool` objects — including MCP tools, which are automatically extracted after agent runs.
### Internal: AgentEvalConverter
Internal class that converts agent-framework types to `EvalItem`. Used by `evaluate_agent()` and `evaluate_workflow()` — not part of the public API:
| Agent Framework | Eval Format |
|---|---|
| `Content.function_call` | `tool_call` in OpenAI chat format |
| `Content.function_result` | `tool_result` in OpenAI chat format |
results.report_url # str | None: portal link (Foundry)
results.assert_passed() # raises AssertionError with details
```
### Core: Orchestration Functions
Provider-agnostic functions that extract data and delegate to evaluators:
| Function | What it does |
|---|---|
| `evaluate_agent()` | Runs agent against test queries (or evaluates pre-existing `responses=`), converts to `EvalItem`s, passes to evaluator. Accepts optional `expected_output=` for ground-truth comparison, `expected_tool_calls=` for tool-correctness evaluation, and `num_repetitions=` for consistency measurement |
| `evaluate_workflow()` | Extracts per-agent data from `WorkflowRunResult`, evaluates each agent and overall output. Per-agent breakdown in `sub_results`. Also accepts `num_repetitions=` |
### Core: Conversation Split Strategies
Multi-turn conversations must be split into query (input) and response (output) halves for evaluation. How you split determines *what you're evaluating*:
**Last-turn split** — split at the last user message. Everything up to and including it is the query context; the agent's subsequent actions are the response:
This evaluates: "Given all the context so far, did the agent answer the latest question well?" Best for response quality at a specific point in the conversation.
**Full-conversation split** — the first user message is the query; everything after is the response:
This evaluates: "Given the original request, did the entire conversation trajectory serve the user?" Best for task completion and overall conversation quality.
**Per-turn split** — produces N eval items from an N-turn conversation. Each turn is evaluated with its cumulative context:
This evaluates each response independently. Best for fine-grained analysis and pinpointing where a conversation goes wrong.
These factorings produce different scores for the same conversation. The framework ships all three as built-in strategies, defaulting to last-turn. Developers can also provide a custom splitter — a function (Python) or `IConversationSplitter` implementation (.NET) — and override the strategy at the call site or per evaluator.
### Azure AI: FoundryEvals
`Evaluator` implementation backed by Azure AI Foundry:
| `evaluate_traces()` | Evaluate from stored response IDs or OTel traces |
| `evaluate_foundry_target()` | Evaluate a Foundry-registered agent or deployment |
### Core: LocalEvaluator and Function Evaluators
`LocalEvaluator` implements the `Evaluator` protocol for fast, API-free evaluation. It runs check functions locally — useful for inner-loop development, CI smoke tests, and combining with cloud-based evaluators.
Built-in checks:
- `keyword_check(*keywords)` — response must contain specified keywords
- `tool_called_check(*tool_names)` — agent must have called specified tools
- `tool_calls_present` — all `expected_tool_calls` names appear in conversation (unordered, extras OK)
- `tool_call_args_match` — expected tool calls match on name + arguments (subset match on args)
Custom function evaluators use `@evaluator` to wrap plain Python functions. The function's **parameter names** determine what data it receives from the `EvalItem`:
```python
from agent_framework import evaluator, LocalEvaluator
# Tier 1: Simple check — just query + response
@evaluator
def is_concise(response: str) -> bool:
return len(response.split()) < 500
# Tier 2: Ground truth — compare against expected output
Return types: `bool`, `float` (≥0.5 = pass), `dict` with `score` or `passed` key, or `CheckResult`.
Async functions are handled automatically — `@evaluator` detects `async def` and produces the right wrapper.
### Example: GAIA Benchmark
[GAIA](https://huggingface.co/gaia-benchmark) tests real-world multi-step tasks with known expected answers. Each task has a question and a ground-truth answer, with optional file attachments. The framework accommodates GAIA's knobs (difficulty levels, file inputs, multi-step tool use) through the existing `EvalItem` fields:
```python
from datasets import load_dataset
from agent_framework import evaluate_agent, evaluator, LocalEvaluator
- Azure-AI re-exports core types for convenience (Python)
## Known Limitations
1. **Tool evaluators require query + agent**: Tool evaluators need tool definition schemas. When using these evaluators with `evaluate_agent(responses=...)`, provide `queries=` and pass an agent with tool definitions.
2. **`model_deployment` always required**: Could potentially be inferred from the Foundry project configuration.
## Open Questions
1. **Red teaming non-registered agents**: Requires Foundry API support for callback-based flows.
2. **Datasets with expected outputs**: A dataset abstraction for pre-populating `expected_output` values across eval runs is a natural next step but not yet designed.
3. **Multi-modal evaluation**: The `conversation` field on `EvalItem` already stores full `Message`/`Content` (Python) and `ChatMessage` (.NET) objects, which can represent multi-modal content (images, audio, structured data). Evaluators that accept the full `EvalItem` or `conversation` parameter can access this content today. However, the convenience shortcuts — `query`/`response` string projections and the `FunctionEvaluator` string overloads — are text-only. Multi-modal-aware evaluators should use the full-item path (`Func<EvalItem, CheckResult>` in .NET, `conversation: list` parameter in Python).
## .NET Implementation Design
### Key Difference: MEAI Ecosystem
Unlike Python, the .NET ecosystem already has `Microsoft.Extensions.AI.Evaluation` (v10.3.0) providing:
- `IEvaluator` — per-item evaluation of `(messages, chatResponse) → EvaluationResult`
The .NET integration uses MEAI's `IEvaluator` directly — no new evaluator interface. Our contribution is the **orchestration layer**: extension methods that run agents, extract data, call `IEvaluator` per item, and aggregate results.
All evaluators implement MEAI's `IEvaluator`. The orchestration layer doesn't need to know which kind — it calls `EvaluateAsync(messages, chatResponse)` per item on all of them. `FoundryEvals` handles batching internally (buffers items, submits once, returns per-item results).
### .NET Core Types
**No new evaluator interface.** Use MEAI's `IEvaluator` directly.
**`AgentEvaluationResults`** — The only new type. Aggregates per-item MEAI `EvaluationResult`s across a batch of queries:
```csharp
public class AgentEvaluationResults
{
public string Provider { get; init; }
public string? ReportUrl { get; init; }
// Per-item — standard MEAI EvaluationResult, unchanged
public IReadOnlyList<EvaluationResult> Items { get; init; }
// Aggregate pass/fail derived from metric interpretations
public int Passed { get; }
public int Failed { get; }
public int Total { get; }
public bool AllPassed { get; }
// Workflow: per-agent breakdown
public IReadOnlyDictionary<string, AgentEvaluationResults>? SubResults { get; init; }
public void AssertAllPassed(string? message = null);
}
```
### .NET Evaluator Implementations
All implement MEAI's `IEvaluator`:
**`LocalEvaluator`** — Runs lambda checks locally, returns `BooleanMetric` per check:
**MEAI evaluators** — Used directly, no adapter needed:
```csharp
var quality = new CompositeEvaluator(
new RelevanceEvaluator(),
new CoherenceEvaluator());
```
**`FoundryEvals`** — Implements `IEvaluator` but batches internally. On first call, buffers the item. On the last item (or when explicitly flushed), submits the batch to Foundry and distributes per-item results:
```csharp
var foundry = new FoundryEvals(projectClient, "gpt-4o");
```
### .NET Orchestration: Extension Methods
```csharp
public static class AgentEvaluationExtensions
{

**Usage:**
```csharp
// MEAI evaluators — just works
var results = await agent.EvaluateAsync(
queries: ["What's the weather?"],
evaluator: new RelevanceEvaluator(),
chatConfiguration: new ChatConfiguration(evalClient));
// Local checks
var results = await agent.EvaluateAsync(
queries: ["What's the weather?"],
evaluator: new LocalEvaluator(
EvalChecks.KeywordCheck("weather")));
// Foundry cloud
var results = await agent.EvaluateAsync(
queries: ["What's the weather?"],
evaluator: new FoundryEvals(projectClient, "gpt-4o"));
// Evaluate existing response (without re-running the agent)
var response = await agent.RunAsync("What's the weather?");
var results = await agent.EvaluateAsync(
responses: response,
queries: ["What's the weather?"],
evaluator: new FoundryEvals(projectClient, "gpt-4o"));
// Mixed — one result per evaluator
var results = await agent.EvaluateAsync(
queries: ["What's the weather?"],
evaluators: [
new LocalEvaluator(EvalChecks.KeywordCheck("weather")),
new RelevanceEvaluator(),
new FoundryEvals(projectClient, "gpt-4o")
],
chatConfiguration: new ChatConfiguration(evalClient));
// Workflow with per-agent breakdown
Run run = await workflowRunner.RunAsync(workflow, "Plan a trip");
var results = await run.EvaluateAsync(
evaluator: new FoundryEvals(projectClient, "gpt-4o"));
```
### .NET Function Evaluators
Typed factory overloads (C# equivalent of Python's `@evaluator`):
```csharp
public static class FunctionEvaluator
{
public static EvalCheck Create(string name, Func<string, bool> check); // response only
public static EvalCheck Create(string name, Func<EvalItem, bool> check); // full item
public static EvalCheck Create(string name, Func<EvalItem, CheckResult> check); // full control
public static EvalCheck Create(string name, Func<string, Task<bool>> check); // async
}
```
`EvalItem` is a lightweight record used only by `FunctionEvaluator` and `LocalEvaluator` to pass context to check functions. It is not part of the `IEvaluator` interface:
```csharp
public record ExpectedToolCall(string Name, IReadOnlyDictionary<string, object>? Arguments = null);
public sealed class EvalItem
{
public EvalItem(string query, string response, IReadOnlyList<ChatMessage> conversation);
public string Query { get; }
public string Response { get; }
public IReadOnlyList<ChatMessage> Conversation { get; }
public IReadOnlyList<AITool>? Tools { get; set; }
public string? ExpectedOutput { get; set; }
public IReadOnlyList<ExpectedToolCall>? ExpectedToolCalls { get; set; }
public string? Context { get; set; }
public IConversationSplitter? Splitter { get; set; }
}
```
### Workflow Data Extraction (.NET)
`run.EvaluateAsync()` walks `Run.OutgoingEvents` via LINQ:
1. Pair `ExecutorInvokedEvent` / `ExecutorCompletedEvent` by `ExecutorId`
2. Extract `AgentResponseEvent` for per-agent `ChatResponse`
3. Call `evaluator.EvaluateAsync()` per invocation
4. Group by `ExecutorId` for per-agent `SubResults`
# CodeAct integration through backend-specific context providers and an `execute_code` tool
## Introduction
**CodeAct** is a pattern in which the model writes executable code — rather than emitting a fixed function-call JSON schema — to plan, transform data, and orchestrate tool calls inside a single sandbox invocation. Instead of requiring a separate model round-trip for every tool call, conditional branch, or data transformation, the model produces a short program that runs in a controlled runtime, calls host-provided tools through a `call_tool(...)` bridge, and returns structured results. This reduces latency, lowers token cost, and lets the model express richer multi-step logic that is difficult to capture in a flat tool-call sequence.
Throughout this ADR, **CodeAct** is the primary term. **Code mode** and **programmatic tool calling** refer to the same capability.
## Context and Problem Statement
We need an architecture design that supports CodeAct in both Python and .NET. This is a necessary capability for the current generation of long-running agents, which need to plan, iterate, transform tool outputs, and execute bounded code inside a controlled runtime — for example, filtering a large result set, computing derived values, or chaining several tool calls with conditional logic — instead of requiring a separate model round-trip for each of those steps. The design should preserve the same behavioral contract across SDKs, but it does not need to use the same internal extension point in each runtime. We also want to standardize on Hyperlight as the initial backend, using the existing Python package and an anticipated .NET binding package once it is available.
Throughout this ADR, **CodeAct** is the primary term. **Code mode** and **programmatic tool calling** refer to the same capability. This ADR uses **CodeAct** consistently.
Model-generated code is treated as untrusted relative to the host process. This ADR assumes the selected backend provides the primary isolation boundary, while the framework is responsible for configuring approvals and capabilities, integrating telemetry, and translating outputs and failures into framework-native shapes. If a backend cannot provide isolation appropriate for its trust model, it is not a suitable CodeAct backend.
The core design question is: **where should CodeAct integrate into the agent pipeline so that both SDKs can offer the same functionality without invasive changes to their core function-calling loops?**
## Decision Drivers
- CodeAct must shape the model-facing surface before model invocation, not only after the model has already chosen tools.
- The design should let users control which tools are available through CodeAct and which remain regular tools only.
- The design must preserve existing session, approval, telemetry, and tool invocation behavior as much as possible.
- The design should define the minimum cross-SDK telemetry and failure semantics for `execute_code`, so Python and .NET do not diverge on basic observability or error handling.
- The design must fit naturally into the extension points that already exist in each SDK.
- The design must be safe for concurrent runs and must not rely on mutating shared agent configuration during invocation.
- The chosen structure should allow multiple backend-specific providers to fit under the same conceptual design over time, even though Hyperlight is the initial target.
- The abstraction should not assume that every backend is a VM-style sandbox; alternative execution models such as Pydantic's Monty should also fit.
- The design should allow `execute_code` to be reused both as a tool-enabled CodeAct runtime and as a standard code interpreter tool implementation.
- The design should remain open to alternative language/runtime modes, such as JavaScript on Hyperlight, rather than baking the abstraction to Python only.
- The design should provide a portable way to configure sandbox capabilities such as file access and network access, including allow-listed outbound domains.
- Using CodeAct should be optional, and installing its runtime or backend dependencies should also be optional.
- Backend-specific dependencies should be isolated behind a small adapter so SDK code is not tightly coupled to an unstable package surface.
## Considered Options
- **Option 1**: Standardize on context provider-based CodeAct with a shared cross-SDK contract and backend-specific public types
- **Option 2**: Implement CodeAct as a dedicated chat-client decorator/wrapper
- **Option 3**: Integrate CodeAct directly into the function invocation layer/FunctionInvokingChatClient
## Pros and Cons of the Options
### Option 1: Standardize on context provider-based CodeAct with a shared cross-SDK contract and backend-specific public types
This option uses `ContextProvider` in Python and `AIContextProvider` in .NET, but standardizes the public concept and behavior.
In this option, the CodeAct tool set is provider-owned: only tools explicitly configured on the concrete CodeAct provider instance are available inside CodeAct, and the provider exposes direct CRUD-style management for tools, file mounts, and outbound network allow-list configuration rather than requiring a separate runtime setup object.
The agent's direct tool surface remains separate. If a tool should be available both through CodeAct and as a normal direct tool, it is configured in both places.
- Good, because both SDKs already have first-class provider concepts intended for per-invocation context shaping.
- Good, because providers operate before model invocation, which is where CodeAct must add instructions and reshape tools.
- Good, because this lets us preserve existing function invocation behavior rather than rewriting it.
- Good, because slightly different internals are acceptable while the public behavior remains aligned.
- Good, because convenience builder/decorator helpers can still be added later on top of the provider model without changing the core design.
- Good, because backend-specific runtime logic can stay inside concrete provider implementations or internal helpers instead of being forced into a lowest-common-denominator public abstraction.
- Good, because the same provider structure can support either an all-or-nothing tool surface or a mixed side-by-side tool surface.
- Good, because users can keep some tools direct-only while allowing other tools to be used from inside CodeAct.
- Good, because a provider-owned CodeAct tool registry avoids mutating or inferring the agent's direct tool surface and can work consistently in both SDKs.
- Good, because the same conceptual design can remain open to `HyperlightCodeActProvider`, a future `MontyCodeActProvider`, and other backend-specific providers over time.
- Good, because `execute_code` can evolve into multiple backend-specific runtime modes rather than being hard-wired to one Python-plus-tools mode.
- Bad, because the provider indirection adds per-run overhead — snapshotting the tool registry, dispatching lifecycle hooks, and building instructions — that a deeper integration point could skip. In practice this overhead is negligible relative to model inference latency and sandbox startup cost.
### Option 2: Implement CodeAct as a dedicated chat-client decorator/wrapper
This option would introduce a CodeAct-specific chat-client decorator that injects instructions and tools directly into the chat request pipeline.
- Good, because this is a natural fit for .NET's `DelegatingChatClient` pipeline.
- Good, because it can also support advanced custom chat-client stacks.
- Good, because backend-specific runtime selection could be hidden inside the decorator implementation.
- Good, because the decorator could also encapsulate mode-specific instruction shaping for tool-enabled versus standalone interpreter behavior.
- Good, because the decorator can decide per request whether the tool surface is exclusive or mixed.
- Bad, because Python can support this by building a custom layering stack on top of a `Raw...Client` and swapping in a different `FunctionInvocationLayer`, but that composition path is more manual than the .NET `DelegatingChatClient` pipeline.
- Bad, because it duplicates responsibilities already handled by provider abstractions.
- Bad, because it makes CodeAct look more transport-specific than it really is.
- Bad, because swappable backends and reusable interpreter or language modes become coupled to chat-client composition rather than modeled as first-class CodeAct concepts.
### Option 3: Integrate CodeAct directly into the function invocation layer/FunctionInvokingChatClient
This option would push CodeAct into Python's `FunctionInvocationLayer` and .NET's `FunctionInvokingChatClient` or related middleware.
- Good, because it is close to tool execution and can observe concrete tool invocation behavior.
- Good, because function middleware may still be useful later for auxiliary auditing or policy around sandbox-originated tool calls.
- Bad, because this is the wrong layer for constructing the model-facing tool surface and prompt instructions.
- Bad, because it does not naturally control whether the model sees an exclusive CodeAct tool surface or a mixed side-by-side tool surface.
- Bad, because it would still require a second mechanism for hiding normal tools and advertising `execute_code`.
- Bad, because it is a weak fit for standalone interpreter modes where no tool-calling loop is needed.
- Bad, because backend selection and CodeAct mode behavior are orthogonal concerns that do not belong in the function invocation layer.
- Bad, because `.NET` would become more tightly coupled to `FunctionInvokingChatClient`, which sits below the agent framework abstraction and is not the natural cross-SDK design seam.
## Approval Model Options
- **Option A**: Bundled approval for the `execute_code` invocation
- **Option B**: Pre-execution inspection of `call_tool(...)` references before approving `execute_code`
- **Option C**: Nested per-tool approvals during `execute_code`
## Pros and Cons of the Approval Options
### Option A: Bundled approval for the `execute_code` invocation
This option grants approval once, before `execute_code` starts. Provider-owned tool calls made from inside that execution run under the same approval. The effective approval of `execute_code` is determined up front from the provider configuration rather than from inspecting which tools are actually called during execution.
- Good, because it is the simplest model to explain and implement consistently in both SDKs.
- Good, because it fits naturally with long-running CodeAct loops where repeated approval interruptions would be disruptive.
- Good, because it does not require static code analysis before execution begins.
- Good, because it keeps the first release focused on the provider integration rather than a more complex approval engine.
- Bad, because approval is coarse-grained and may cover more activity than the user expected.
- Bad, because it provides less visibility into which provider-owned tools or capabilities will be exercised during the run.
### Option B: Pre-execution inspection of `call_tool(...)` references before approving `execute_code`
This option inspects submitted code for statically discoverable `call_tool("tool_name", ...)` references before execution starts and uses that information to shape the approval request.
- Good, because it can show users more detail up front while still keeping approval at a single pre-execution moment.
- Good, because it matches the common case where tool names are spelled out directly in the generated code.
- Good, because it can coexist with bundled approval as a more informative variant of the same UX.
- Bad, because the analysis is inherently best-effort and cannot reliably predict dynamic behavior.
- Bad, because it requires duplicated parsing or inspection logic that does not replace runtime enforcement.
### Option C: Nested per-tool approvals during `execute_code`
This option requests approval when sandboxed code actually attempts to invoke a provider-owned tool that requires approval.
- Good, because it aligns approval with real behavior rather than predicted behavior.
- Good, because it gives precise visibility into which provider-owned tools are being used.
- Good, because it can allow some tool calls while rejecting others within the same execution.
- Bad, because it interrupts long-running CodeAct flows and can degrade the user experience significantly.
- Bad, because it requires more complex runtime plumbing and approval UX in both SDKs.
- Bad, because repeated approval pauses may make CodeAct less useful for the exact long-running scenarios that motivate this feature.
## Decision Outcomes
### Decision 1: Integration seam and public structure
Chosen option: **Option 1: Standardize on provider-based CodeAct with a shared cross-SDK contract and backend-specific public types**, because it is the only option that maps cleanly to both SDKs, lets us reshape instructions and tools before model invocation, and avoids invasive changes to the existing function invocation loops while still allowing multiple backend-specific providers and multiple runtime modes to fit under the same structure later.
### Decision 2: Initial approval model
Chosen option: **Option A: Bundled approval for the `execute_code` invocation**, because it is the smallest approval model that fits both SDKs, works well for long-running CodeAct flows, and does not force us to standardize a more complex inspection or policy engine in the first release.
This follows the spirit of the current Python tool approval flow, where `FunctionTool` uses `approval_mode="always_require" | "never_require"` and the auto-invocation loop escalates the whole batch when any called tool requires approval.
### Design summary
We standardize the **public concept** of CodeAct across SDKs while allowing each SDK to use the extension point that fits it best.
- Python uses a `ContextProvider`.
- .NET uses an `AIContextProvider`.
- The term **CodeAct context provider** is used throughout this ADR as a design concept, not as a required public base type. Public SDK APIs should prefer concrete backend-specific types such as `HyperlightCodeActProvider` rather than a public abstract `CodeActContextProvider` or a public `CodeActExecutor` parameter.
- CodeAct support should ship as an optional package in each SDK rather than as part of the core package, so users who do not need CodeAct do not take on its installation and dependency footprint. That optional package may still depend on a few small, backward-compatible hooks in the host SDK's core agent pipeline.
- There is no separate runtime setup object in the chosen design. Concrete providers manage their provider-owned CodeAct tool registry, file mounts, and outbound network allow-list configuration directly through CRUD-style methods on the provider itself.
- At a high level, CodeAct is exposed through backend-specific context providers that contribute an `execute_code` tool, own the CodeAct-specific tool registry, and carry backend capability configuration such as filesystem and network access.
- The initial approval model is bundled approval for `execute_code`, using the same `approval_mode="always_require" | "never_require"` vocabulary as regular tools.
- The CodeAct provider exposes a default `approval_mode` for `execute_code`. If the provider default is `always_require`, `execute_code` is always treated as `always_require` regardless of the provider-owned tool registry. If the provider default is `never_require`, the effective approval for `execute_code` is derived from the provider-owned CodeAct tool registry captured for the run.
- If every provider-owned CodeAct tool in that registry has `approval_mode="never_require"`, `execute_code` is treated as `never_require`. If any provider-owned CodeAct tool in that registry has `approval_mode="always_require"`, `execute_code` is treated as `always_require`, even if the generated code may not end up calling that tool.
- Approval is granted before `execute_code` starts, and provider-owned tool calls made from inside that execution run under the same approval.
- Direct-only agent tools do not affect the approval of `execute_code`; only the provider-owned CodeAct tool registry participates in that calculation.
- This approval model is intentionally conservative. If one sensitive provider-owned tool forces `execute_code` to require approval more often than desired, the mitigation is to keep that tool direct-only or split it into a different provider/tool surface rather than trying to infer per-run tool usage up front.
- Configuring filesystem and network capability state on the provider, including adding file mounts or outbound network allow-list entries, is itself the approval for those capabilities in the initial model.
- Each `execute_code` invocation must start from a clean execution state; in-memory variables and other ephemeral interpreter/runtime state must not persist across separate calls. When a provider exposes a workspace, mounted files, or a writable artifact/output area, those files are the supported persistence mechanism across calls and are treated as external state rather than interpreter state.
- Mutating the provider's tool registry or capability configuration while a run is in flight is allowed, but it only affects subsequent runs. Provider implementations must snapshot the effective state for each run and synchronize concurrent access so shared provider instances remain safe across concurrent runs.
- The minimum cross-SDK telemetry contract is that `execute_code` is traced as a normal tool invocation nested inside the surrounding agent run, and provider-owned tool calls made from inside CodeAct continue to emit ordinary tool-invocation telemetry. Backend-specific resource metrics are optional extensions, not a required new top-level cross-SDK event model.
- Timeout, out-of-memory, backend crash, and similar sandbox failures are all execution failures of `execute_code` and should surface as structured error results rather than backend-specific public DTOs. Partial textual or file outputs may be returned only when the backend can report them unambiguously; callers must not rely on partial-output recovery as a portable guarantee.
- The provider-based structure preserves room for future pre-execution inspection and nested per-tool approvals if later experience shows they are needed.
- Concrete backend-specific providers may still use small SDK-local helpers or adapters internally, but that split is an implementation detail rather than a public API requirement.
Detailed language-specific implementation notes are specified in:
### Minimal core hooks required by the optional package
CodeAct remains optional at the package level, but the optional package depends on a small number of hooks that must live in the host SDK because the agent pipeline owns model invocation and per-run tool resolution.
- Python depends on the existing `ContextProvider` lifecycle, `SessionContext.extend_instructions(...)`, `SessionContext.extend_tools(...)`, per-run runtime tool access via `SessionContext.options["tools"]`, and the shared `ApprovalMode` vocabulary used by `FunctionTool`.
- .NET depends on the existing `AIContextProvider` seam, agent/runtime support for applying providers before model invocation, and the existing chat-client or function-invocation seams that concrete implementations use to contribute `execute_code`.
These hooks are backward-compatible because they only expose or forward per-run state that core already owns. Behavior changes only when a concrete CodeAct provider opts in and uses them.
### Concrete provider implementation contract
The design does not require a public abstract `CodeActContextProvider` base class, but it does require a stable implementation contract for concrete providers.
- Concrete providers should expose a standard capability surface at construction time, with SDK-appropriate naming for:
- approval mode
- workspace root
- file mounts
- allowed outbound targets plus any per-target method or policy restrictions needed by the backend
- Separate public `filesystem_mode` / `network_mode` flags are not required by the cross-SDK contract. Filesystem access may be disabled implicitly until a workspace or file mounts are configured, and outbound network may be disabled implicitly until an allow-list or equivalent outbound policy entry is configured.
- Concrete providers should expose direct CRUD-style methods for managing the provider-owned CodeAct tool registry, file mounts, and outbound network allow-list configuration, rather than requiring callers to construct a separate runtime setup object.
- Concrete providers should implement their host SDK's provider lifecycle hooks to:
- build CodeAct instructions,
- add `execute_code`,
- snapshot the effective CodeAct tool registry and capability settings for the run,
- compute the effective approval requirement for `execute_code`,
- configure file access and network access for the backend,
- prepare or restore execution state,
- execute code,
- and translate backend output into framework-native content.
- Any internal abstract/helper surface shared by multiple concrete providers should standardize responsibilities for:
- instruction construction,
- file-access configuration,
- network-access configuration,
- environment preparation/restoration,
- code execution,
- and output-to-content conversion.
- Backend execution output should reuse existing framework-native content/message primitives rather than introducing backend-specific public result DTOs.
AI agents are vulnerable to prompt injection attacks where malicious instructions embedded in external content (e.g., API responses, user input) can manipulate agent behavior. Traditional defenses rely on heuristics and prompt engineering, which are not deterministic and can be bypassed.
We need a systematic, deterministic defense mechanism that prevents untrusted content from influencing agent behavior, provides verifiable security guarantees, maintains audit trails for compliance, and integrates seamlessly with the existing agent framework.
## Decision Drivers
- Agents must not execute actions influenced by untrusted external content (prompt injection defense).
- The solution must provide deterministic, verifiable security guarantees — not heuristic-based.
- The solution must maintain audit trails for compliance and security reviews.
- The solution must integrate non-invasively with the existing middleware pipeline.
- The solution must be opt-in and backwards compatible with existing agents.
- Developer experience must remain simple with a clear security model.
## Considered Options
- Information-flow control with label-based middleware (FIDES)
- Prompt engineering defense
- Content sanitization
- Separate agent instances
- Runtime monitoring only
## Decision Outcome
Chosen option: "Information-flow control with label-based middleware (FIDES)", because it is the only option that provides deterministic, formally verifiable security guarantees while integrating non-invasively with the existing middleware pipeline and remaining fully backwards compatible.
FIDES (Flow Integrity Deterministic Enforcement System) is a label-based security system with four core components:
1. **Content Labeling System** — `IntegrityLabel` (TRUSTED/UNTRUSTED) and `ConfidentialityLabel` (PUBLIC/PRIVATE/USER_IDENTITY) with most-restrictive-wins combination policy.
2. **Middleware-Based Enforcement** — `LabelTrackingFunctionMiddleware` for automatic label propagation and `PolicyEnforcementFunctionMiddleware` for pre-execution policy checks.
3. **Variable Indirection** — `ContentVariableStore` and `VariableReferenceContent` for physical isolation of untrusted content from the LLM context.
4. **Quarantined Execution** — `quarantined_llm` and `inspect_variable` tools for isolated processing of untrusted data with audit logging.
### Consequences
- Good, because it provides deterministic security guarantees about what untrusted content can influence.
- Good, because labels provide a clear audit trail of trust propagation.
- Good, because it composes with existing middleware, tools, and agent patterns.
- Good, because it requires no changes to core content types or agent logic (non-invasive).
- Good, because policies are configurable per agent or tool.
- Good, because audit logs support compliance and security reviews.
- Bad, because middleware adds latency to every tool call.
- Bad, because the variable store consumes memory for untrusted content.
- Bad, because developers must understand the label system.
- Bad, because it does not defend against all attack vectors (e.g., training data poisoning).
- Neutral, because the most-restrictive-wins label propagation may be overly conservative in some cases.
- Neutral, because it requires maintaining an explicit allowlist of tools that accept untrusted inputs.
## Pros and Cons of the Options
### Information-flow control with label-based middleware (FIDES)
Enable Agent Framework users to consume Foundry **toolboxes** — named, versioned bundles of tool definitions stored server-side in an Azure AI Foundry project — directly from `FoundryChatClient`, without dropping to the raw `azure-ai-projects` SDK.
A user who has configured a toolbox in the Foundry portal (or via the raw SDK) should be able to load it into an agent with a single call:
**Success metric:** an agent can consume a toolbox with no manual handling of version-resolution logic on the user's side.
## What is the problem being solved?
`azure-ai-projects==2.1.0a20260409002` ships a new `BetaToolboxesOperations` surface, reachable as `AIProjectClient.beta.toolboxes` on the raw SDK client (and therefore as `FoundryChatClient.project_client.beta.toolboxes` through our wrapper), that lets teams:
- Group related hosted tools (code interpreter, file search, MCP, web search, etc.) under a named toolbox
- Version toolboxes immutably, so agents can pin to a specific configuration for production stability
- Share toolboxes across multiple agents in a project
However, consuming a toolbox from the framework today requires:
1. Knowing the raw SDK accessor path (`client.project_client.beta.toolboxes`)
2. Making two calls for the common case — `.get(name)` to find the default version, then `.get_version(name, version)` to actually retrieve tools
3. Manually unpacking `toolbox.tools` before passing them to `Agent(tools=...)`
None of this is hard, but it's the kind of boilerplate that should live in the client. Every other hosted tool in `FoundryChatClient` (code interpreter, file search, web search, image generation, MCP) already has a factory method (`get_code_interpreter_tool()`, etc.). Toolbox support should fit the same shape on the chat-client composition surface.
## API Changes
### One new method on the FoundryChatClient surface
The public toolbox-consumption surface lands on:
- `RawFoundryChatClient` (inherited by `FoundryChatClient`) in `_chat_client.py`
The implementation delegates to shared helper functions in `_tools.py` so there is a single source of truth for the SDK calls.
**Scope note:** `FoundryAgent` is intentionally not part of this design. `FoundryAgent` is the runtime surface for invoking an already-configured server-side Foundry agent; if that agent should use a toolbox, the toolbox/tools should already be configured on the Foundry side (UI or `azure-ai-projects` authoring flow) before MAF connects to it.
**Scope note:** Authoring a server-side agent whose definition references a toolbox (via `PromptAgentDefinition(tools=toolbox.tools, ...)` + `client.agents.create_version(...)`) is deliberately outside MAF scope. That is an `azure-ai-projects` / service-resource authoring concern, not a future MAF feature. Users who need it should use the raw Azure SDK directly.
```python
async def get_toolbox(
self,
name: str,
*,
version: str | None = None,
) -> ToolboxVersionObject:
"""Fetch a Foundry toolbox by name.
If ``version`` is ``None``, resolves the toolbox's current default version
(two requests). If ``version`` is specified, fetches that version directly
(single request).
:param name: The name of the toolbox.
:param version: Optional immutable version identifier to pin to.
:return: A ``ToolboxVersionObject``. Pass its ``tools`` attribute to
``Agent(tools=toolbox.tools)``.
:raises azure.core.exceptions.ResourceNotFoundError: If the toolbox or
version does not exist.
"""
```
### Return types: raw SDK models, no custom wrappers
Methods return the `azure.ai.projects.models` types directly:
No custom wrapper classes are defined. Returning the SDK types directly:
- Eliminates maintenance overhead of keeping a custom wrapper aligned with SDK changes
- Matches the existing convention — `get_code_interpreter_tool()` returns the raw `CodeInterpreterTool` SDK type
- Means any new fields the SDK adds to these types flow through automatically
`Agent(..., tools=...)` will accept the fetched toolbox object directly by flattening to `toolbox.tools` internally.
### Design decisions
**Instance methods, not `@staticmethod` factories.** Existing `get_code_interpreter_tool()` / `get_mcp_tool()` / etc. are `@staticmethod` because they're pure factories with no network I/O. Toolbox fetching requires the project client, so these new methods must be instance methods. This is a deliberate departure from the existing-factory pattern, justified by the async-with-I/O nature of the operation.
**Raw SDK type passthrough (no custom wrappers).** There is only one toolbox type in the Foundry SDK and maintaining a shadow wrapper would create alignment risk as the SDK evolves. The raw `ToolboxVersionObject` and `ToolboxObject` carry all the fields users need. Individual tools inside `toolbox.tools` are the same `azure.ai.projects.models.Tool` subclasses returned by other factory methods.
**Two-request default-version path.** When `version=None`, implementation calls `.get(name)` to find `default_version`, then `.get_version(name, default_version)` for the tools. Caching the default-version mapping was considered and rejected — default versions can change server-side via `update(default_version=...)`, and a stale cache would silently give callers the wrong tools. Two requests at agent setup is acceptable.
**No discovery/listing surface in MAF.** Discovery is intentionally left to the raw `azure-ai-projects` client. MAF does not currently expose project-resource listing surfaces for many other Foundry resources (deployments, vector stores, agents, etc.), so the toolbox design stays narrowly focused on explicit retrieval by name/version.
**Shared helpers in `_tools.py`.** The SDK-call helper function (`fetch_toolbox`) lives in a shared module so the chat-client surface stays thin and the request logic remains centralized.
**`tools=toolbox` convenience, not a new wrapper type.** Although `get_toolbox()` returns the raw `ToolboxVersionObject`, Agent Framework can still support `tools=toolbox` / `tools=[toolbox]` by flattening the toolbox's `.tools` internally. That matches existing SDK ergonomics where some higher-level objects can be placed directly in `tools=` and unpacked underneath, without introducing a public `FoundryToolbox` wrapper.
**Errors pass through unchanged.** `ResourceNotFoundError`, `HttpResponseError`, etc. from the SDK propagate as-is. No framework-specific exception hierarchy.
## E2E Code Samples
### Primary sample
New file: `samples/02-agents/providers/foundry/foundry_chat_client_with_toolbox.py`
```python
import asyncio
from agent_framework import Agent
from agent_framework.foundry import FoundryChatClient
Normalized name precedence for `include_names` / `exclude_names`:
1. MCP `server_label`
2. generic tool `name`
3. fallback tool `type`
This keeps `get_toolbox()` as a thin fetch API and makes selection an explicit,
local post-processing step, while still allowing the ergonomic
`select_toolbox_tools(toolbox, ...)` call shape.
## Native vs MCP consumption of a Foundry toolbox
A Foundry toolbox can be consumed two ways. This design adds new implementation work only for the first:
1. **Native consumption (in scope).** Tools execute inside Foundry's agent runtime. `get_toolbox()` returns the `ToolboxVersionObject` whose `.tools` attribute carries typed tool configs that the runtime interprets server-side. This design is specifically for `FoundryChatClient`-backed local agent composition.
2. **MCP consumption (already supported through existing MCP abstractions).** A Foundry toolbox can also be exposed as an MCP server. In that case, use the existing `MCPStreamableHTTPTool(name=..., url=...)` — it already handles this path with any chat client (Foundry, OpenAI, Anthropic, etc.). No new Foundry-specific API is needed for MCP-exposed toolboxes in this design.
### MCPStreamableHTTPTool example for a Foundry toolbox endpoint
If Foundry gives you an MCP endpoint for the toolbox (for example from the
toolbox details UI / endpoint surface), the existing MCP client path is:
```python
from agent_framework import Agent, MCPStreamableHTTPTool
from agent_framework.openai import OpenAIChatClient
toolbox_mcp = MCPStreamableHTTPTool(
name="research_tools",
url="https://<foundry-toolbox-mcp-endpoint>",
)
agent = Agent(
client=OpenAIChatClient(),
instructions="You are a research assistant.",
tools=[toolbox_mcp],
)
```
This is a different integration shape than `get_toolbox(...).tools`:
- `get_toolbox(...).tools` = **native Foundry hosted-tool configs** interpreted by the
Foundry runtime
- `MCPStreamableHTTPTool(name=..., url=...)` = **live MCP server connection** to a
toolbox endpoint
The design in this spec adds first-class support only for the native hosted-tool
path. The MCP path is already served by the framework's existing MCP abstractions.
These paths are not unified because they have fundamentally different execution models. Native toolbox tools are declarative configs the Foundry runtime executes; MCP consumption is a live wire protocol to a running server.
**MCP authentication inside a toolbox** is handled server-side via `project_connection_id` on individual `MCPTool` entries (OAuth connection objects configured in the Foundry project). The client never holds bearer tokens. Consent flow handling (`CONSENT_REQUIRED` → user-visible consent URL) happens during `agent.run()`, not during toolbox fetching — see Non-goals.
## Testing Strategy
Unit tests in `packages/foundry/tests/test_toolbox.py` with mocked `project_client.beta.toolboxes`. A single opt-in live round-trip, `test_integration_get_toolbox_round_trip_against_real_project`, is marked `@pytest.mark.integration`; it is skipped by default and only runs when the required Foundry credentials are available.
Coverage:
- `get_toolbox(name, version="v3")` — explicit version, single request. Assert `.get` not called, `.get_version` awaited once, returns `ToolboxVersionObject`.
- `get_toolbox(name)` — default-version resolution. Assert `.get` then `.get_version` called in order with correct args.
- Error propagation — `ResourceNotFoundError` from `.get` propagates unchanged.
- Tool passthrough — heterogeneous tool list (`CodeInterpreterTool`, `MCPTool(project_connection_id=...)`) passes through unchanged. Asserts `project_connection_id` survives.
- Agent integration smoke — `tools=toolbox` / `tools=[toolbox]` flatten to the underlying toolbox tools.
- Multiple toolbox composition smoke — `tools=[toolbox_a, toolbox_b]` flattens into a single agent tool list.
- `get_toolbox_tool_name()` — selection-name precedence is MCP `server_label`, then `name`, then `type`.
- `select_toolbox_tools(toolbox, include_names=...)` — selects by normalized tool names directly from a fetched toolbox object.
- `select_toolbox_tools(toolbox, include_types=...)` — selects by tool types with `Literal`-guided IDE completion.
- Runtime consent-flow handling for OAuth MCP tools (see Non-goals).
- Toolbox discovery/listing (`list_toolboxes`, `list_toolbox_versions`) — deliberately left to the raw Azure SDK.
- Full CRUD (`create_version`, `update`, `delete`) and server-side agent authoring — see Non-goals.
Live Foundry API integration is exercised only through the opt-in `@pytest.mark.integration` round-trip noted above; it is not part of the default test run.
The core `normalize_tools` function in `packages/core/agent_framework/_tools.py` already supports flattening composite tool inputs. Toolbox support extends that behavior so a fetched `ToolboxVersionObject` is treated as a composite tool source and flattened to its `.tools`.
That enables:
- `tools=toolbox`
- `tools=[toolbox]`
- `tools=[local_tool, toolbox]`
- `tools=[toolbox_a, toolbox_b]`
while still keeping `select_toolbox_tools(toolbox.tools, ...)` available for partial selection before the final agent construction step.
## Telemetry
Telemetry for toolbox support has two separate goals:
1. **Observe toolbox API access** — `get_toolbox()`
2. **Observe toolbox usage during agent runs** — when users pass toolbox-derived tools into `Agent(..., tools=...)`
### Request telemetry for toolbox API access
When Agent Framework constructs the `AIProjectClient` internally for `FoundryChatClient`, it already sets:
carry the standard MAF user-agent marker and can be queried in backend request logs the same way as other Foundry SDK calls made through framework-owned clients.
Important constraint: if the caller passes an already-constructed `project_client`, Agent Framework does **not** mutate it to inject the MAF user-agent. In that case, toolbox API request telemetry reflects whatever user-agent behavior that external client was configured with.
### Runtime telemetry for toolbox usage on agent runs
Tool-level telemetry already captures which hosted Foundry tools are available / invoked during agent execution. The remaining gap is **toolbox provenance**: once the user writes `tools=toolbox` (or otherwise flattens the toolbox into tool configs), the framework sees only raw tool configs and no longer knows which toolbox name/version supplied them.
The design for closing the **client-side** observability gap is **internal provenance tracking**, not user-supplied metadata and not a new public wrapper type.
#### Provenance model
Note: this section is still under investigation.
When `get_toolbox()` or `list_toolbox_versions()` returns a `ToolboxVersionObject`, Agent Framework will attach private provenance metadata to:
- the returned toolbox object
- each tool inside `toolbox.tools`
Recommended shape (private, internal-only):
```python
tool._maf_toolbox_sources = [
{
"id": toolbox.id,
"name": toolbox.name,
"version": toolbox.version,
}
]
```
Key properties of this approach:
- **No new public API surface** — users still work with raw `ToolboxVersionObject` / `ToolboxObject`
- **No user burden** — callers do not need to stamp metadata manually
- **Provenance follows the tool objects** — works with:
- `tools=toolbox.tools`
- `tools=[toolbox_a.tools, toolbox_b.tools]`
- `tools=[*toolbox_a.tools, *toolbox_b.tools]`
- **Private attributes are not serialized** into the actual request payload sent to the model/service, so this metadata does not leak into the tool definition body
This is intentionally preferred over introducing a new public `FoundryToolbox` wrapper purely for telemetry, and preferred over a separate global provenance registry. The provenance lives on the existing tool objects so list-copying and chat-option merging naturally preserve it.
#### Span enrichment
When Agent / chat telemetry computes span attributes for a run, it should inspect the final tool list and aggregate the private toolbox provenance from any tool objects that carry it. The aggregated values are then emitted as attributes on the existing run/chat spans.
Suggested custom attributes:
- `agent_framework.foundry.toolbox.ids`
- `agent_framework.foundry.toolbox.names`
- `agent_framework.foundry.toolbox.versions`
- or a single compact attribute such as `agent_framework.foundry.toolbox.sources=["research_tools@1","some_other_tools@3"]`
The single compact `toolbox.sources` form is preferred for initial implementation because it is easy to query and easy to render from combined tool lists.
#### Scope of telemetry changes
This design does **not** require new spans. It enriches existing telemetry:
- toolbox API access continues to rely on request logs + Azure SDK distributed tracing + MAF user-agent
- agent/chat execution spans gain toolbox provenance attributes when toolbox-derived tools are present
Implementation-wise, this design most likely touches:
- `packages/foundry/agent_framework_foundry/_tools.py` — to stamp provenance on fetched toolbox objects / tools
- `packages/core/agent_framework/observability.py` — to aggregate provenance into span attributes
#### Important limitation: no server-side toolbox telemetry solution yet
Private provenance attached to tool objects is only useful on the client side. It
does **not** go over the wire to the Foundry service because those private fields
are intentionally not serialized into the request payload.
That means this design can support:
- local OpenTelemetry / exporter spans emitted by Agent Framework
- local attribution of a run to one or more fetched toolboxes
but it does **not** solve:
- server-side request-log attribution of a model/tool run back to a toolbox
- backend/database queries that need the service itself to know "this tool came from toolbox X"
At the moment, we do not have a satisfactory design for server-side toolbox
telemetry. The service would require additional structured information on the
request, and there is no accepted mechanism in this design yet for projecting
toolbox provenance into a server-visible field/header/metadata shape.
So the telemetry story in this spec is explicitly limited to **client-side
toolbox telemetry**. Server-side toolbox attribution remains an open question and
requires either:
- new service/API support, or
- a later framework design for emitting additional server-visible request metadata.
#### Deliberate non-goals for telemetry
- No requirement for users to pass explicit toolbox metadata in `default_options["metadata"]` or `run(..., options=...)`
- No new public `FoundryToolbox` wrapper type just to preserve attribution
- No attempted server-side attribution mechanism in this design (for example a custom request header or request metadata field) until there is a validated end-to-end contract for it
## Non-goals / Future Work
Explicitly out of scope for this design. Each is a separate design and PR when needed.
1. **Create/update/delete toolboxes from code.** CRUD is rare in agent consumption flows. Users who need it drop to `client.project_client.beta.toolboxes.create_version(...)`, `.update(...)`, `.delete(...)` directly.
2. **Server-side agent authoring from toolbox.** Creating a `PromptAgentDefinition(tools=toolbox.tools)` + `client.agents.create_version(...)` is a future feature covering agent authoring from code. The toolbox read API provides the building blocks; the authoring helpers are a separate design.
3. **OAuth consent-flow runtime handling.** When a toolbox contains MCP tools with `project_connection_id` pointing to an OAuth connection, the runtime may return `CONSENT_REQUIRED` mid-run. This is a runtime concern separate from toolbox fetching.
4. **Live integration tests.** This PR ships unit tests only.
5. **Toolbox caching or refresh APIs.** Each `get_toolbox()` call hits the network. Users who want caching wrap the call themselves.
**FIDES** is a comprehensive deterministic prompt injection defense system for the agent framework. The implementation provides label-based security mechanisms to defend against prompt injection attacks by tracking integrity and confidentiality of content throughout agent execution.
5. **Security Tools** - Specialized tools for safe handling of untrusted content (`quarantined_llm`, `inspect_variable`)
6. **SecureAgentConfig** - Context provider for easy secure agent configuration
7. **Message-Level Label Tracking** - Track labels on every message in the conversation (Phase 1)
## Implementation Details
### Files Created
1. **`python/packages/core/agent_framework/security.py`** (~2950 lines — all security primitives, middleware, tools, and configuration in a single public module)
- **Label Combination**: Most restrictive policy (UNTRUSTED + metadata merging)
- **Serialization**: Full support for `to_dict()` and `from_dict()`
### 2. Per-Item Embedded Labels
Tools returning mixed-trust data embed labels on individual items using `Content.from_text()`:
```python
import json
from agent_framework import Content, tool
@tool(description="Fetch emails from inbox")
async def fetch_emails(count: int = 5) -> list[Content]:
return [
Content.from_text(
json.dumps({
"id": email["id"],
"body": email["body"],
}),
additional_properties={
"security_label": {
"integrity": "trusted" if email["internal"] else "untrusted",
"confidentiality": "private",
}
),
)
for email in emails
]
```
These embedded labels are automatically consumed by `LabelTrackingFunctionMiddleware`, which:
- Extracts the `security_label` from `additional_properties`
- Uses the embedded label as the highest-priority source for that item
- Automatically hides UNTRUSTED items in the variable store
- Replaces hidden items with `VariableReferenceContent` in the LLM context
- Preserves TRUSTED items visible to the LLM without tainting the context label
This enables tools to return mixed-trust data where some items (internal emails) remain visible while untrusted items (external emails) are automatically hidden without manual intervention.
},
)
for email in emails
]
```
### 3. Automatic Variable Hiding
This feature automatically hides any UNTRUSTED content returned by tools while keeping the hiding logic transparent to the developer. Developers do not need to manually call `store_untrusted_content()`. This allows the LLM /agent's context to remain clean and secure. Key aspects include:
- **Automatic Detection**: Middleware checks integrity label after each tool call
- **Automatic Storage**: UNTRUSTED results/items stored in variable store
- **Complete auditability**: All security events logged
The system ensures that untrusted content never directly reaches the LLM context and that all tool calls are policy-checked based on the cumulative security state before execution.
This document is intentionally focused on the .NET design and public API surface.
The initial public .NET type described here is `HyperlightCodeActProvider`. Future .NET backends, such as Monty, should follow the same conceptual model with their own concrete provider types rather than through a public abstract base class or a public executor parameter.
## What is the goal of this feature?
Goals:
- .NET developers can enable CodeAct through an `AIContextProvider`-based integration.
- Developers can configure a provider-owned CodeAct tool set that is separate from the agent's direct tool surface.
- Developers can use the same `execute_code` concept for both tool-enabled CodeAct and a standard code interpreter tool implementation.
- Developers can swap execution backends over time, starting with Hyperlight while keeping room for alternatives.
- Developers can configure execution capabilities such as workspace mounts and outbound network allow lists in a portable way.
Success Metric:
- .NET samples exist for both a tool-enabled CodeAct mode and a standard interpreter mode.
Implementation-free outcome:
- A .NET developer can attach a backend-specific CodeAct provider, choose which tools are available inside CodeAct, and configure execution capabilities without rewriting the function invocation loop or ChatClient pipeline.
## What is the problem being solved?
The cross-SDK problem statement and decision rationale live in the [ADR](../../decisions/0024-codeact-integration.md). The items below narrow that statement to .NET-specific design concerns:
- Today, the easiest way to prototype CodeAct in .NET is to manually configure an `AIFunction` and wire instructions — this is fragile and requires understanding internal sandbox lifecycle details.
- There is no first-class .NET design that simultaneously covers Hyperlight-backed CodeAct now, future backend-specific providers, and both tool-enabled and interpreter modes.
- Sandbox capabilities such as mounted file access and outbound network access need a portable configuration model instead of ad hoc backend-specific wiring.
- Approval behavior needs to be explicit and configurable, mapping to .NET's existing `ApprovalRequiredAIFunction` wrapper mechanism.
## API Changes
### CodeAct contract
#### Terminology
- **CodeAct** is the primary term.
- `execute_code` is the model-facing tool name used by the initial .NET provider in this spec.
- Tool-enabled versus interpreter behavior is derived from the presence of CodeAct-managed tools, not from a separate public profile object.
#### Provider-owned CodeAct tool registry
A concrete .NET CodeAct provider owns the set of tools available through `call_tool(...)` inside CodeAct.
Rules:
- Only tools explicitly configured on the concrete provider instance are available inside CodeAct.
- The provider must not infer its CodeAct-managed tool set from the agent's direct tool configuration (`ChatClientAgentOptions.Tools` or `AIContext.Tools`).
- Exclusive versus mixed behavior is achieved by where tools are configured, not by rewriting the agent's direct tool list.
Implications:
- **CodeAct-only tool**: configured on the concrete CodeAct provider only.
- **Direct-only tool**: configured on the agent only.
- **Tool available both ways**: configured on both the agent and the concrete CodeAct provider.
#### Managing tools and capabilities after provider construction
There is no separate runtime setup object in the .NET design. CodeAct tools, file mounts, and outbound network allow-list state are managed directly on the provider through CRUD-style registry methods.
- The provider-owned CodeAct tool registry is keyed by tool name (from `AIFunction.Name`).
- `AddTools(...)` adds new tools and replaces an existing provider-owned registration when the same tool name is added again.
- `GetTools()` returns the provider's current configured CodeAct tool registry.
- `RemoveTools(...)` removes provider-owned CodeAct tools by name.
- `ClearTools()` removes all provider-owned CodeAct tools.
- File mounts are keyed by sandbox mount path.
- `AddFileMounts(...)` adds new file mounts and replaces an existing mount when the same mount path is added again.
- `GetFileMounts()` returns the provider's current configured file mounts.
- `RemoveFileMounts(...)` removes file mounts by mount path.
- `ClearFileMounts()` removes all configured file mounts.
- Allowed domains are keyed by normalized target string.
- `AddAllowedDomains(...)` adds allow-list entries and replaces an existing entry when the same target is added again.
- `GetAllowedDomains()` returns the current outbound allow-list entries.
- `RemoveAllowedDomains(...)` removes allow-list entries by target.
- `ClearAllowedDomains()` removes all configured allow-list entries.
- Tool, file-mount, and network-allow-list mutations affect subsequent runs only; runs already in progress keep the snapshot captured at run start.
- The provider must snapshot its effective tool registry and capability state at the start of each run so concurrent execution remains deterministic.
#### Approval model
The initial .NET design follows the ADR's bundled approval decision and maps to the existing `ApprovalRequiredAIFunction` wrapper from `Microsoft.Extensions.AI.Abstractions`:
- The provider exposes a default `ApprovalMode` for `execute_code` (enum: `CodeActApprovalMode.AlwaysRequire` / `CodeActApprovalMode.NeverRequire`).
Effective `execute_code` approval is computed as follows:
- If the provider default is `AlwaysRequire`, `execute_code` requires approval.
- If the provider default is `NeverRequire`, the provider evaluates the provider-owned CodeAct tool registry snapshot for that run.
- If every provider-owned CodeAct tool in that snapshot is not an `ApprovalRequiredAIFunction`, `execute_code` does not require approval.
- If any provider-owned CodeAct tool in that snapshot is an `ApprovalRequiredAIFunction`, `execute_code` requires approval, even if the generated code may not call that tool.
- When the effective approval resolves to `AlwaysRequire`, the generated `execute_code` function is wrapped in `ApprovalRequiredAIFunction` before being added to the `AIContext.Tools`.
- Provider-owned tool calls made through `call_tool(...)` during that execution run use the approval already determined for `execute_code`.
- Direct-only agent tools are excluded from this calculation.
- File and network capabilities do not create a separate runtime approval check in the initial model; configuring them on the provider is itself the approval for those capabilities.
This is intentionally conservative and matches the shape of the existing .NET function-tool approval flow, where `ApprovalRequiredAIFunction` signals to the `ChatClientAgent` that user approval is needed before invocation.
#### Shared execution flow
On each run:
1. `ProvideAIContextAsync(...)` snapshots the current CodeAct-managed tool registry and capability settings.
2. Computes the effective approval requirement for `execute_code` from the provider default plus the snapshotted tool registry.
3. Builds provider-defined instructions.
4. Builds a run-scoped `execute_code``AIFunction` from the snapshot (optionally wrapped in `ApprovalRequiredAIFunction`).
5. Returns an `AIContext` containing the instructions and `execute_code` tool.
6. When `execute_code` is invoked by the model, the run-scoped function creates or reuses an execution environment.
7. If the current provider mode exposes host tools, `call_tool(...)` is bound only to the provider-owned tool registry snapshot.
8. Code is executed and results converted to a JSON result string.
Caching rules:
- The Hyperlight backend supports snapshots: the provider caches a reusable clean snapshot after the first sandbox initialization.
- No mutable per-run execution state may be shared across concurrent runs.
- In-memory interpreter state does not persist across separate `execute_code` calls.
- Configured workspace files, mounted files, and any writable artifact/output area are the supported persistence mechanism across calls when the backend exposes them.
### .NET public API
#### Core types
```csharp
/// <summary>
/// Represents a host-to-sandbox file mount configuration.
/// </summary>
/// <param name="HostPath">Absolute or relative path on the host filesystem.</param>
/// <param name="MountPath">Path inside the sandbox (e.g. "/input/data.csv").</param>

/// </param>
public sealed record AllowedDomain(string Target, IReadOnlyList<string>? Methods = null);
/// <summary>
/// Controls the approval behavior for execute_code invocations.
/// </summary>
public enum CodeActApprovalMode
{
/// <summary>execute_code always requires user approval.</summary>
AlwaysRequire,
/// <summary>
/// Approval is derived from the provider-owned tool registry:
/// if any tool is an ApprovalRequiredAIFunction, execute_code requires approval.
/// </summary>
NeverRequire,
}
```
#### HyperlightCodeActProvider
```csharp
/// <summary>
/// An AIContextProvider that enables CodeAct execution through the
/// Hyperlight sandbox backend.
/// </summary>
/// <remarks>
/// <para>
/// This provider injects an <c>execute_code</c> tool into the model-facing
- snapshotting the current CodeAct-managed tool registry and capability settings for the run,
- computing the effective approval requirement for `execute_code` from the provider default and the snapshotted tool registry,
- building a short CodeAct guidance instruction string,
- building a run-scoped `execute_code``AIFunction` from the snapshot,
- optionally wrapping it in `ApprovalRequiredAIFunction` when approval is required,
- and returning an `AIContext` with `Instructions` and `Tools` set.
These steps run on every invocation rather than once at construction time because the provider supports CRUD mutations between runs, concurrent runs need independent snapshots, and the effective approval and instructions depend on the tool registry state captured at run start.
The provider overrides `StateKeys` to return the configured `StateKey` from options, enabling multiple provider instances on the same agent without key collisions.
Mutating the provider after `ProvideAIContextAsync(...)` has captured a run-scoped snapshot is allowed, but it affects subsequent runs only. Provider implementations synchronize state capture and CRUD operations so shared provider instances remain safe across concurrent runs.
#### AIFunction-to-sandbox tool bridging
The Hyperlight sandbox's `RegisterTool(name, Func<string, string>)` accepts a synchronous JSON-in / JSON-out delegate. Provider-owned CodeAct tools are `AIFunction` instances that are async and cancellation-aware.
Bridging strategy:
- At sandbox initialization time, the provider registers each CodeAct-managed tool with the sandbox using the raw JSON overload: `RegisterTool(name, Func<string, string>)`.
- When the sandbox guest calls `call_tool("name", ...)`, the bridge delegate:
1. Deserializes the JSON arguments.
2. Invokes `AIFunction.InvokeAsync(...)` synchronously (via `GetAwaiter().GetResult()`) since the sandbox FFI callback is inherently synchronous.
3. Serializes the result back to JSON.
- This sync-over-async bridge is a known pragmatic trade-off constrained by the Hyperlight FFI boundary. It is safe because:
- Sandbox execution already runs on the thread pool (via `Task.Run`).
- The FFI callback runs on a worker thread with no synchronization context.
- If the Hyperlight .NET SDK later adds async tool registration, the bridge should migrate to that.
#### Runtime behavior
- `ProvideAIContextAsync(...)` adds a short CodeAct guidance block through `AIContext.Instructions`.
- `ProvideAIContextAsync(...)` adds `execute_code` through `AIContext.Tools`.
- The detailed `call_tool(...)`, sandbox-tool, and capability guidance is carried by the `execute_code` function's `Description`.
- `execute_code` invokes the configured Hyperlight sandbox guest.
- If the current CodeAct tool registry snapshot is non-empty, the runtime injects `call_tool(...)` bound to the provider-owned tool registry.
- The provider does not inspect or mutate the agent's `ChatClientAgentOptions.Tools` or the incoming `AIContext.Tools` to determine its CodeAct tool set.
- The provider snapshots the current CodeAct tool registry and capability state at run start, so later registry and allow-list mutations only affect future runs.
- Interpreter versus tool-enabled behavior is derived from the presence of CodeAct-managed tools.
- `execute_code` is traced like a normal tool invocation within the surrounding agent run.
#### Backend integration
Initial public provider:
- `HyperlightCodeActProvider`
Backend-specific notes:
- **Hyperlight**
- The provider internally creates a `SandboxBuilder` from the options and uses the `Sandbox` API from `HyperlightSandbox.Api`.
- The provider uses snapshot/restore to ensure clean execution state per `execute_code` invocation: a "warm" snapshot is taken after the first no-op initialization run, and restored before each subsequent execution.
- Network access is denied by default and is enabled through `Sandbox.AllowDomain(...)` per-target allow-list entries.
- Guest module resolution: if `ModulePath` is null for the Wasm backend, the provider attempts to locate a packaged Python guest module (equivalent to the Python SDK's `python_guest.path` resolution).
#### Capability handling
Capabilities are first-class `HyperlightCodeActProviderOptions` properties and provider-managed CRUD surfaces:
- `WorkspaceRoot`
- `FileMounts`
- `AllowedDomains`
Enabling access means:
- Configuring `WorkspaceRoot` or any `FileMounts` enables the sandbox filesystem surface exposed through `/input` and `/output`.
- Leaving both `WorkspaceRoot` and `FileMounts` unset means no filesystem surface is configured.
- Adding any `AllowedDomains` entry enables outbound access only for the configured targets; leaving it empty means network access is disabled without a separate network mode flag.
Backends may implement stricter semantics than these top-level settings.
#### Execution output representation
Backend execution output maps to a JSON result string returned from the `execute_code``AIFunction`:
```json
{
"stdout": "Hello world\n",
"stderr": "",
"exit_code": 0,
"success": true
}
```
Execution failures should surface readable error text in the `stderr` field and a non-zero `exit_code`. Timeouts, out-of-memory conditions, backend crashes, and similar sandbox failures are all `execute_code` failures and should surface as structured error results. Partial textual or file outputs may be returned only when the backend can report them unambiguously.
#### `execute_code` input contract
```json
{
"type": "object",
"properties": {
"code": {
"type": "string",
"description": "Code to execute using the provider's configured backend/runtime behavior."
}
},
"required": ["code"]
}
```
#### Thread safety and concurrency
- All CRUD methods (`AddTools`, `RemoveTools`, `AddFileMounts`, etc.) are synchronized via an internal lock.
- `ProvideAIContextAsync(...)` acquires the lock to snapshot current state, then releases it before building the run-scoped function. The run-scoped function closes over the immutable snapshot, not mutable provider state.
- Concurrent `execute_code` invocations from different runs use independent sandbox instances or synchronized access to a shared sandbox with snapshot/restore.
- Workspace directories (`WorkspaceRoot`, `FileMounts`) are external shared state: concurrent runs against the same workspace can race on files. This is the user's responsibility to manage (e.g., by using per-run output directories or separate provider instances).
### HyperlightExecuteCodeFunction
The provider package also exports a standalone `HyperlightExecuteCodeFunction` for direct-tool scenarios where a provider lifecycle is not needed. This is the .NET equivalent of the Python `HyperlightExecuteCodeTool`.
```csharp
/// <summary>
/// A standalone execute_code AIFunction backed by a Hyperlight sandbox.
/// Use this for manual/static wiring when the AIContextProvider lifecycle
/// is not needed.
/// </summary>
public sealed class HyperlightExecuteCodeFunction : IDisposable
{
/// <summary>
/// Creates a new standalone code execution function.
var sendEmail = AIFunctionFactory.Create(SendEmail, name: "send_email");
var agent = chatClient.AsAIAgent(
instructions: "You are a helpful assistant.",
options: new ChatClientAgentOptions
{
Tools = [sendEmail], // direct-only tool
AIContextProviders = [codeact],
});
await using var session = await agent.CreateSessionAsync();
var response = await agent.InvokeAsync("Analyze the latest docs", session);
```
### Standard code interpreter mode
```csharp
var codeact = new HyperlightCodeActProvider(new HyperlightCodeActProviderOptions
{
WorkspaceRoot = "./data",
});
var agent = chatClient.AsAIAgent(
instructions: "You are a code interpreter.",
options: new ChatClientAgentOptions
{
AIContextProviders = [codeact],
});
```
### Manual static wiring (no provider lifecycle)
When the tool registry and capability configuration are fixed, the provider lifecycle can be skipped entirely. Build the `execute_code` function and instructions once and pass them directly to the agent:
```csharp
using var executeCode = new HyperlightExecuteCodeFunction(
// execute_code will be wrapped in ApprovalRequiredAIFunction because
// at least one managed tool (delete_records) requires approval.
var agent = chatClient.AsAIAgent(
instructions: "You are a helpful assistant.",
options: new ChatClientAgentOptions
{
AIContextProviders = [codeact],
});
```
## Relationship to hyperlight-sandbox .NET SDK
This design depends on the .NET SDK being added in [hyperlight-dev/hyperlight-sandbox#46](https://github.com/hyperlight-dev/hyperlight-sandbox/pull/46). Key types consumed from that SDK:
| `SandboxSnapshot` | Checkpoint/restore for clean state per execution |
The provider package (`Microsoft.Agents.AI.Hyperlight`) takes a NuGet dependency on `Hyperlight.HyperlightSandbox.Api` and `Microsoft.Extensions.AI.Abstractions`. It does **not** depend on `HyperlightSandbox.Extensions.AI` (`CodeExecutionTool`) — the provider implements its own sandbox lifecycle management with run-scoped snapshots to support concurrent invocations safely.
## Package structure
The CodeAct Hyperlight provider ships as an optional NuGet package:
This keeps CodeAct and its native sandbox dependencies optional — users who do not need CodeAct do not take on the Hyperlight installation and dependency footprint.
## Open questions
1. **Guest module distribution**: How should the default Python guest module (`.aot` file) be distributed for .NET consumers? Options include a separate NuGet package with native assets, a runtime download, or requiring users to build/provide their own.
2. **Async tool registration**: If the Hyperlight .NET SDK adds async tool callback support in a future release, the sync-over-async bridge should be replaced. This is tracked as a known technical debt item.
3. **Output file access**: The Hyperlight sandbox exposes `GetOutputFiles()` and `OutputPath` for retrieving files written by guest code. The initial design returns these as part of the JSON result. A future iteration could surface output files as framework-native content (e.g., `DataContent` or URI references).
4. **Multiple sandbox instances for concurrency**: The current design uses synchronized access to a single sandbox with snapshot/restore. An alternative pooling strategy (one sandbox per concurrent run) could improve throughput at the cost of memory. This is deferred to implementation time.
This document is intentionally focused on the Python design and public API surface.
The initial public Python type described here is `HyperlightCodeActProvider`. Future Python backends, such as Monty, should follow the same conceptual model with their own concrete provider types rather than through a public abstract base class or a public executor parameter.
## What is the goal of this feature?
Goals:
- Python developers can enable CodeAct through a `ContextProvider`-based integration.
- Developers can configure a provider-owned CodeAct tool set that is separate from the agent's direct `tools=` surface.
- Developers can use the same `execute_code` concept for both tool-enabled CodeAct and a standard code interpreter tool implementation.
- Developers can swap execution backends over time, starting with Hyperlight while keeping room for alternatives such as Pydantic's Monty.
- Developers can configure execution capabilities such as workspace mounts and outbound network allow lists in a portable way.
Success Metric:
- Python samples exist for both a tool-enabled CodeAct mode and a standard interpreter mode.
Implementation-free outcome:
- A Python developer can attach a backend-specific CodeAct provider, choose which tools are available inside CodeAct, and configure execution capabilities without rewriting the function invocation loop.
## What is the problem being solved?
The cross-SDK problem statement and decision rationale live in the [ADR](../../decisions/0024-codeact-integration.md). The items below narrow that statement to Python-specific design concerns:
- Today, the easiest way to prototype CodeAct is to infer or reshape the agent's direct tool surface, which is fragile and hard to reason about.
- In Python, inferring a CodeAct tool surface from generic agent tool configuration is fragile and hard to reason about.
- There is no first-class Python design that simultaneously covers Hyperlight-backed CodeAct now, future backend-specific providers such as Monty, and both tool-enabled and interpreter modes.
- Sandbox capabilities such as mounted file access and outbound network access need a portable configuration model instead of ad hoc backend-specific wiring.
- Approval behavior needs to be explicit and configurable, especially when CodeAct and direct tool calling may both be available.
## API Changes
### CodeAct contract
#### Terminology
- **CodeAct** is the primary term.
- **Code mode**, **codemode**, and **programmatic tool calling** refer to the same concept in this document.
- `execute_code` is the model-facing tool name used by the initial Python providers in this spec.
#### Provider-owned CodeAct tool registry
A concrete Python CodeAct provider owns the set of tools available through `call_tool(...)` inside CodeAct.
Rules:
- Only tools explicitly configured on the concrete provider instance are available inside CodeAct.
- The provider must not infer its CodeAct-managed tool set from the agent's direct `tools=` configuration.
- Exclusive versus mixed behavior is achieved by where tools are configured, not by rewriting the agent's direct tool list.
Implications:
- **CodeAct-only tool**: configured on the concrete CodeAct provider only.
- **Direct-only tool**: configured on the agent only.
- **Tool available both ways**: configured on both the agent and the concrete CodeAct provider.
#### Managing tools and capabilities after provider construction
There is no separate runtime setup object in the Python design. CodeAct tools, file mounts, and outbound network allow-list state are managed directly on the provider through CRUD-style registry methods.
- The provider-owned CodeAct tool registry is keyed by tool name.
- `add_tools(...)` adds new tools and replaces an existing provider-owned registration when the same tool name is added again.
- `get_tools()` returns the provider's current configured CodeAct tool registry.
- `remove_tool(...)` removes provider-owned CodeAct tools by name.
- `clear_tools()` removes all provider-owned CodeAct tools.
- File mounts are keyed by sandbox mount path.
- `add_file_mounts(...)` adds new file mounts and replaces an existing mount when the same mount path is added again.
- `get_file_mounts()` returns the provider's current configured file mounts.
- `remove_file_mount(...)` removes file mounts by mount path.
- `clear_file_mounts()` removes all configured file mounts.
- Allowed domains are keyed by normalized target string.
- `add_allowed_domains(...)` adds allow-list entries and replaces an existing entry when the same target is added again.
- `get_allowed_domains()` returns the current outbound allow-list entries.
- `remove_allowed_domain(...)` removes allow-list entries by target.
- `clear_allowed_domains()` removes all configured allow-list entries.
- Tool, file-mount, and network-allow-list mutations affect subsequent runs only; runs already in progress keep the snapshot captured at run start.
- The provider must snapshot its effective tool registry and capability state at the start of each run so concurrent execution remains deterministic.
#### Approval model
The initial Python design follows the ADR's initial approval decision and reuses the existing tool approval vocabulary from `agent_framework._tools`:
- `approval_mode="always_require"`
- `approval_mode="never_require"`
The provider exposes a default `approval_mode` for `execute_code`.
Effective `execute_code` approval is computed as follows:
- If the provider default is `always_require`, `execute_code` requires approval.
- If the provider default is `never_require`, the provider evaluates the provider-owned CodeAct tool registry snapshot for that run.
- If every provider-owned CodeAct tool in that snapshot is `never_require`, `execute_code` is `never_require`.
- If any provider-owned CodeAct tool in that snapshot is `always_require`, `execute_code` is `always_require`, even if the generated code may not call that tool.
- Provider-owned tool calls made through `call_tool(...)` during that execution run use the approval already determined for `execute_code`.
- Direct-only agent tools are excluded from this calculation.
- File and network capabilities do not create a separate runtime approval check in the initial model; configuring them on the provider, including adding file mounts or outbound network allow-list entries, is itself the approval for those capabilities.
This is intentionally conservative and matches the shape of the current function-tool approval flow, where `FunctionTool` uses `always_require` / `never_require` and the auto-invocation loop escalates the whole batch if any called tool requires approval.
If one sensitive provider-owned tool causes `execute_code` to require approval more often than desired, the mitigation is to keep that tool direct-only or expose it through a different CodeAct provider/tool surface. The initial model does not try to infer whether generated code will actually call that tool before approval.
If the framework later standardizes pre-execution inspection or nested per-tool approvals, the Python provider surface can grow to expose that explicitly. The initial design does not assume that those extra modes are required.
#### Shared execution flow
On each run:
1. Resolve the provider's backend/runtime behavior, capabilities, provider default `approval_mode`, and provider-owned tool registry.
2. Compute the effective approval requirement for `execute_code` from the provider default plus the provider-owned tool registry snapshot.
3. Build provider-defined instructions.
4. Add `execute_code` to the model-facing tool surface.
5. Invoke the underlying model.
6. When `execute_code` is called, create or reuse an execution environment keyed by provider type, backend setup identity, capability configuration, and provider-owned tool signature.
7. If the current provider mode exposes host tools, expose `call_tool(...)` bound only to the provider-owned tool registry.
8. Execute code and convert results to framework-native content objects.
Caching rules:
- Backends that support snapshots may cache a reusable clean snapshot.
- Backends that do not support snapshots may still cache warm initialization artifacts.
- No mutable per-run execution state may be shared across concurrent runs.
- In-memory interpreter state does not persist across separate `execute_code` calls.
- Configured workspace files, mounted files, and any writable artifact/output area are the supported persistence mechanism across calls when the backend exposes them.
- snapshotting the current CodeAct-managed tool registry and capability settings for the run,
- computing the effective approval requirement for `execute_code` from the provider default and the snapshotted tool registry,
- adding a short CodeAct guidance block,
- adding `execute_code` to the run through `SessionContext.extend_tools(...)`,
- and wiring any backend-specific execution state needed for the run.
These steps run on every invocation rather than once at construction time because the provider supports CRUD mutations between runs, concurrent runs need independent snapshots, and the effective approval and instructions depend on the tool registry state captured at run start. When the tool registry and capability configuration are fixed for the lifetime of the agent, the manual wiring pattern (see `codeact_manual_wiring.py`) can be used instead, which passes the tool and instructions directly to the `Agent` constructor and avoids the per-run provider lifecycle entirely.
If the provider stores anything in `state`, that value must stay JSON-serializable.
Mutating the provider after `before_run(...)` has captured a run-scoped snapshot is allowed, but it affects subsequent runs only. Provider implementations should synchronize state capture and CRUD operations so shared provider instances remain safe across concurrent runs.
`after_run(...)` is responsible for any backend-specific cleanup or post-processing that must happen after the model invocation completes.
If shared internal helpers are introduced later for multiple concrete providers, they should standardize responsibilities for:
- building instructions,
- computing effective approval,
- configuring file access,
- configuring network access,
- preparing or restoring execution state,
- executing code,
- and converting backend output into framework-native `Content`.
#### Runtime behavior
- `before_run(...)` adds a short CodeAct guidance block through `SessionContext.extend_instructions(...)`.
- `before_run(...)` adds `execute_code` through `SessionContext.extend_tools(...)`.
- The detailed `call_tool(...)`, sandbox-tool, and capability guidance is carried by `execute_code.description`.
- `execute_code` invokes the configured Hyperlight sandbox guest.
- If the current CodeAct tool registry is non-empty, the runtime injects `call_tool(...)` bound to the provider-owned tool registry.
- The provider does not inspect or mutate `Agent.default_options["tools"]` or `context.options["tools"]` to determine its CodeAct tool set.
- The provider snapshots the current CodeAct tool registry and capability state at run start, so later registry and allow-list mutations only affect future runs.
- Interpreter versus tool-enabled behavior is derived from the concrete provider and the presence of CodeAct-managed tools, not from a separate public profile object.
- `execute_code` should be traced like a normal tool invocation within the surrounding agent run, and provider-owned tool calls executed through `call_tool(...)` should continue to emit ordinary tool invocation telemetry.
#### Backend integration
Initial public provider:
- `HyperlightCodeActProvider`
Backend-specific notes:
- **Hyperlight**
- Provider construction needs a guest artifact via `module`, which may be a packaged guest module name or a path to a compiled guest artifact.
- File access maps naturally to Hyperlight Sandbox's read-only `/input` and writable `/output` capability model.
- Network access is denied by default and is enabled through per-target allow-list entries.
- **Monty**
- A future `MontyCodeActProvider` should be a separate public type rather than a `HyperlightCodeActProvider` mode.
- Monty does not expose built-in filesystem or network access directly inside the interpreter.
- File and URL access are mediated through host-provided external functions, so a Monty provider would need to translate provider settings into virtual files and allow-checked callbacks.
- Monty setup may also include backend-specific inputs such as `script_name`, optional type-check stubs, or restored snapshots.
#### Capability handling
Capabilities are first-class `HyperlightCodeActProvider` init parameters and provider-managed CRUD surfaces:
- `workspace_root`
- `file_mounts`
- `allowed_domains`
Concrete providers should normalize these settings internally. Hyperlight can map them directly to sandbox capabilities, while Monty must enforce them through host-mediated file and network functions and may apply stricter URL-level checks than the public provider surface expresses.
Expected management split:
- `workspace_root` remains a direct configuration value on the provider,
- file mounts are managed through provider CRUD methods,
- outbound allow-list entries are managed through provider CRUD methods.
Enabling access means:
- Configuring `workspace_root` or any `file_mounts` enables the sandbox filesystem surface exposed through `/input` and `/output`.
- Leaving both `workspace_root` and `file_mounts` unset means no filesystem surface is configured.
- Adding any `allowed_domains` entry enables outbound access only for the configured targets; leaving it empty means network access is disabled without a separate `network_mode` flag.
- A string target allows all backend-supported methods for that target; an explicit tuple or `AllowedDomain` entry narrows the methods for that target.
Backends may implement stricter semantics than these top-level settings. For example, Hyperlight naturally maps file access to `/input` and `/output`, while Monty would enforce equivalent policy through host-provided callbacks rather than direct interpreter I/O.
#### Execution output representation
Backend execution output should be translated into existing AF `Content` values rather than a custom `CodeActExecutionResult` type.
Use the existing content model from `agent_framework._types`, for example:
- `Content.from_code_interpreter_tool_result(outputs=[...])` to surface the overall result of sandboxed code execution,
- `Content.from_text(...)` for plain textual output,
- `Content.from_data(...)` or `Content.from_uri(...)` for generated files or binary artifacts,
- `Content.from_error(...)` for execution failures,
- and `Content.from_function_result(..., result=list[Content])` when surfacing the final result of `execute_code` through the normal tool result path.
#### `execute_code` input contract
```json
{
"type": "object",
"properties": {
"code": {
"type": "string",
"description": "Code to execute using the provider's configured backend/runtime behavior."
}
},
"required": ["code"]
}
```
Execution failures should surface readable error text and structured error `Content`, not a custom backend result object.
Timeouts, out-of-memory conditions, backend crashes, and similar sandbox failures are all `execute_code` failures and should surface as structured error content. Partial textual or file outputs may be returned only when the backend can report them unambiguously; callers should not rely on partial-output recovery as a portable contract.
## E2E Code Samples
### Tool-enabled CodeAct mode
```python
codeact = HyperlightCodeActProvider(
tools=[fetch_docs, query_data],
workspace_root="./workdir",
allowed_domains=[("api.github.com", "GET")],
)
codeact.add_tools([lookup_user])
agent = Agent(
client=client,
name="assistant",
tools=[send_email], # direct-only tool
context_providers=[codeact],
)
```
### Standard code interpreter mode
```python
codeact = HyperlightCodeActProvider(
workspace_root="./data",
)
agent = Agent(
client=client,
name="interpreter",
context_providers=[codeact],
)
```
### Manual static wiring (no per-run provider lifecycle)
When the tool registry and capability configuration are fixed, the provider lifecycle can be skipped entirely. Build the `execute_code` tool and instructions once and pass them directly to the agent:
- Official docs (Microsoft Learn): <https://learn.microsoft.com/agent-framework/integrations/azure-functions>
## Document structure
| File | Purpose |
| --- | --- |
| `README.md` | Main technical overview: architecture, hosting models, orchestration patterns, and links to samples. |
| `durable-agents-ttl.md` | Deep-dive on session Time-To-Live (TTL) configuration and behavior. |
Add new sibling documents when a topic is too detailed for the README (e.g., a new feature like reliable streaming or MCP tool exposure). Keep the README focused on orientation and link out to siblings for depth.
## Writing guidelines
- **Audience**: Developers already familiar with the Microsoft Agent Framework who want to understand what durability adds and how to use it.
- **Host-agnostic first**: Durable agents work in console apps, Azure Functions, and any Durable Task–compatible host. Show host-agnostic patterns (plain orchestration functions, `IServiceCollection` registration) before Azure Functions–specific patterns. Avoid giving the impression that Azure Functions is the only hosting option.
- **Both languages**: Always include C# and Python examples side by side. Keep them equivalent in functionality.
- **Callout syntax**: Use GitHub-flavored callouts (`> [!NOTE]`, `> [!IMPORTANT]`, `> [!WARNING]`) rather than bold-text callouts (`> **Note:** ...`).
- **Line length**: Do not wrap long lines. Rely on text viewers / renderers for line wrapping.
- **Tables**: Use spaces around pipes in separator rows (`| --- |` not `|---|`).
- **Code snippets**: Keep them minimal and self-contained. Omit boilerplate (using statements, environment variable reads) unless the snippet is specifically about setup.
- **Cross-references**: Link to Microsoft Learn for conceptual background (Durable Entities, Durable Task Scheduler, Azure Functions). Link to sibling docs within this directory for feature deep-dives.
## Linting
Run markdownlint on all documents before committing, with line-length checks disabled:
Durable agents extend the standard Microsoft Agent Framework with **durable state management** powered by the Durable Task framework. An ordinary Agent Framework agent runs in-process: its conversation history lives in memory and is lost when the process ends. A durable agent persists conversation history and execution state in external storage so that sessions survive process restarts, failures, and scale-out events.
| Capability | Ordinary agent | Durable agent |
| --- | --- | --- |
| Conversation history | In-memory only | Durably persisted |
| Failure recovery | State lost on crash | Automatically resumed |
| Multi-instance scale-out | Not supported | Any worker can resume a session |
| Human-in-the-loop | Must keep process alive | Can wait days/weeks with zero compute |
| Hosting | Any process | Console app, Azure Functions, or any Durable Task–compatible host |

## How durable agents work
Durable agents are implemented on top of [Durable Entities](https://learn.microsoft.com/azure/azure-functions/durable/durable-functions-entities) (also called "virtual actors"). Each **agent session** maps to one entity instance whose state contains the full conversation history. When you send a message to a durable agent, the following happens:
1. The message is dispatched to the entity identified by an `AgentSessionId` (a composite of the agent name and a unique session key).
2. The entity loads its persisted `DurableAgentState`, which includes the complete conversation history.
3. The entity invokes the underlying `AIAgent` with the full conversation history, collects the response, and appends both the request and the response to the state.
4. The updated state is persisted back to durable storage automatically.
Because the entity framework serializes access to each entity instance, concurrent messages to the same session are processed one at a time, eliminating race conditions.
### Agent session identity
Every durable agent session is identified by an `AgentSessionId`, which has two components:
- **Name**– the registered name of the agent (case-insensitive).
- **Key**– a unique session key (case-sensitive), typically a GUID.
The session ID is mapped to an underlying Durable Task entity ID with a `dafx-` prefix (e.g., `dafx-joker`). This naming convention is consistent across both .NET and Python implementations.
## Architecture
### .NET
The .NET implementation consists of two NuGet packages:
| Package | Purpose |
| --- | --- |
| `Microsoft.Agents.AI.DurableTask` | Core durable agent types: `DurableAIAgent`, `AgentEntity`, `DurableAgentSession`, `AgentSessionId`, `DurableAgentsOptions`, and the state model. |
| `Microsoft.Agents.AI.Hosting.AzureFunctions` | Azure Functions hosting integration: auto-generated HTTP endpoints, MCP tool triggers, entity function triggers, and the `ConfigureDurableAgents` extension method on `FunctionsApplicationBuilder`. |
Key types:
- **`DurableAIAgent`** – A subclass of `AIAgent` used *inside orchestrations*. Obtained via `context.GetAgent("agentName")`, it routes `RunAsync` calls through the orchestration's entity APIs so that each call is checkpointed.
- **`DurableAIAgentProxy`** – A subclass of `AIAgent` used *outside orchestrations* (e.g., from HTTP triggers or console apps). It signals the entity via `DurableTaskClient` and polls for the response.
- **`AgentEntity`** – The `TaskEntity<DurableAgentState>` that hosts the real agent. It loads the registered `AIAgent` by name, wraps it in an `EntityAgentWrapper`, feeds it the full conversation history, and persists the result.
- **`DurableAgentSession`** – An `AgentSession` subclass that carries the `AgentSessionId`.
- **`DurableAgentsOptions`** – Builder for registering agents and configuring TTL.
### Python
The core Python implementation is in the `agent-framework-durabletask` package (`python/packages/durabletask`). Azure Functions hosting (including `AgentFunctionApp`) is in the separate `agent-framework-azurefunctions` package (`python/packages/azurefunctions`).
Key types:
- **`DurableAIAgent`** – A generic proxy (`DurableAIAgent[TaskT]`) implementing `SupportsAgentRun`. Returns a `TaskT` from `run()` — either an `AgentResponse` (client context) or a `DurableAgentTask` (orchestration context, must be `yield`ed).
- **`DurableAIAgentWorker`** – Wraps a `TaskHubGrpcWorker` and registers agents as durable entities via `add_agent()`.
- **`DurableAIAgentClient`** – Wraps a `TaskHubGrpcClient` for external callers. `get_agent()` returns a `DurableAIAgent[AgentResponse]`.
- **`DurableAIAgentOrchestrationContext`** – Wraps an `OrchestrationContext` for use inside orchestrations. `get_agent()` returns a `DurableAIAgent[DurableAgentTask]`.
- **`AgentEntity`** – Platform-agnostic agent execution logic that manages state, invokes the agent, handles streaming, and calls response callbacks.
## Hosting models
### Azure Functions
The recommended production hosting model. A single call to `ConfigureDurableAgents` (C#) or `AgentFunctionApp` (Python) automatically:
- Registers agent entities with the Durable Task worker.
- Generates HTTP endpoints at `/api/agents/{agentName}/run` for each registered agent.
- Supports `thread_id` query parameter / JSON field and the `x-ms-thread-id` response header for session continuity.
- Supports fire-and-forget via the `x-ms-wait-for-response: false` header (returns HTTP 202).
For self-hosted or non-serverless scenarios, register durable agents via `IServiceCollection.ConfigureDurableAgents` (.NET) or `DurableAIAgentWorker` (Python) with explicit Durable Task worker and client configuration.
**C# example:**
```csharp
IHost host = Host.CreateDefaultBuilder(args)
.ConfigureServices(services =>
{
services.ConfigureDurableAgents(
options => options.AddAIAgent(agent),
workerBuilder: b => b.UseDurableTaskScheduler(connectionString),
clientBuilder: b => b.UseDurableTaskScheduler(connectionString));
Durable agents can be composed into deterministic, checkpointed workflows using Durable Task orchestrations. The orchestration framework replays orchestrator code on failure, so completed agent calls are not re-executed.
### Patterns
| Pattern | Description |
| --- | --- |
| **Sequential (chaining)** | Call agents one after another, passing outputs forward. |
| **Parallel (fan-out/fan-in)** | Run multiple agents concurrently and aggregate results. |
| **Conditional** | Branch orchestration logic based on structured agent output. |
| **Human-in-the-loop** | Pause for external events (approvals, feedback) with optional timeouts. |
### Using agents in orchestrations
Inside an orchestration function, obtain a `DurableAIAgent` via the orchestration context. Each agent gets its own session (created with `CreateSessionAsync` / `create_session`), and you can call the same agent multiple times on the same session to maintain conversation context across sequential invocations.
# Get a durable agent reference — works in any host (standalone worker, Azure Functions, etc.)
writer = agent_ctx.get_agent("WriterAgent")
# Create a session to maintain conversation context across multiple calls
session = writer.create_session()
# First call: generate an initial draft
draft = yield writer.run(
messages="Write a concise inspirational sentence about learning.",
session=session,
)
# Second call: refine the draft — the agent sees the full conversation history
refined = yield writer.run(
messages=f"Improve this further while keeping it under 25 words: {draft.text}",
session=session,
)
return refined.text
```
> [!IMPORTANT]
> In .NET, `DurableAIAgent.RunAsync<T>` deliberately avoids `ConfigureAwait(false)` because the Durable Task Framework uses a custom synchronization context — all continuations must run on the orchestration thread.
## Streaming and response callbacks
Durable agents do not support true end-to-end streaming because entity operations are request/response. However, **reliable streaming** is supported via response callbacks:
- **`IAgentResponseHandler`** (.NET) or **`AgentResponseCallbackProtocol`** (Python) – Implement this interface to receive streaming updates as the underlying agent generates them (e.g., push tokens to a Redis Stream for client consumption).
- The entity still returns the complete `AgentResponse` after the stream is fully consumed.
- Clients can reconnect and resume reading from a cursor-based stream (e.g., Redis Streams) without losing messages.
See the **Reliable Streaming** samples for a complete implementation using Redis Streams.
## Session TTL (Time-To-Live)
Durable agent sessions support automatic cleanup via configurable TTL. See [Session TTL](durable-agents-ttl.md) for details on configuration, behavior, and best practices.
## Observability
When using the [Durable Task Scheduler](https://learn.microsoft.com/azure/azure-functions/durable/durable-task-scheduler/durable-task-scheduler) as the durable backend, you get built-in observability through its dashboard:
- **Conversation history**– View complete chat history for each agent session.
- **Orchestration visualization**– See multi-agent execution flows, including parallel branches and conditional logic.
The durable agents automatically maintain conversation history and state for each session. Without automatic cleanup, this state can accumulate indefinitely, consuming storage resources and increasing costs. The Time-To-Live (TTL) feature provides automatic cleanup of idle agent sessions, ensuring that sessions are automatically deleted after a period of inactivity.
## What is TTL?
Time-To-Live (TTL) is a configurable duration that determines how long an agent session state will be retained after its last interaction. When an agent session is idle (no messages sent to it) for longer than the TTL period, the session state is automatically deleted. Each new interaction with an agent resets the TTL timer, extending the session's lifetime.
## Benefits
- **Automatic cleanup**: No manual intervention required to clean up idle agent sessions
- **Cost optimization**: Reduces storage costs by automatically removing unused session state
- **Resource management**: Prevents unbounded growth of agent session state in storage
- **Configurable**: Set TTL globally or per-agent type to match your application's needs
## Configuration
TTL can be configured at two levels:
1. **Global default TTL**: Applies to all agent sessions unless overridden
2. **Per-agent type TTL**: Overrides the global default for specific agent types
Additionally, you can configure a **minimum deletion delay** that controls how frequently deletion operations are scheduled. The default value is 5 minutes, and the maximum allowed value is also 5 minutes.
> [!NOTE]
> Reducing the minimum deletion delay below 5 minutes can be useful for testing or for ensuring rapid cleanup of short-lived agent sessions. However, this can also increase the load on the system and should be used with caution.
### Default values
- **Default TTL**: 14 days
- **Minimum TTL deletion delay**: 5 minutes (maximum allowed value, subject to change in future releases)
### Configuration examples
#### .NET
```csharp
// Configure global default TTL and minimum signal delay
services.ConfigureDurableAgents(
options =>
{
// Set global default TTL to 7 days
options.DefaultTimeToLive = TimeSpan.FromDays(7);
// Add agents (will use global default TTL)
options.AddAIAgent(myAgent);
});
// Configure per-agent TTL
services.ConfigureDurableAgents(
options =>
{
options.DefaultTimeToLive = TimeSpan.FromDays(14); // Global default
The following sections describe how TTL works in detail.
### Expiration tracking
Each agent session maintains an expiration timestamp in its internally managed state that is updated whenever the session processes a message:
1. When a message is sent to an agent session, the expiration time is set to `current time + TTL`
2. The runtime schedules a delete operation for the expiration time (subject to minimum delay constraints)
3. When the delete operation runs, if the current time is past the expiration time, the session state is deleted. Otherwise, the delete operation is rescheduled for the next expiration time.
### State deletion
When an agent session expires, its entire state is deleted, including:
- Conversation history
- Any custom state data
- Expiration timestamps
After deletion, if a message is sent to the same agent session, a new session is created with a fresh conversation history.
## Behavior examples
The following examples illustrate how TTL works in different scenarios.
### Example 1: Agent session expires after TTL
1. Agent configured with 30-day TTL
2. User sends message at Day 0 → agent session created, expiration set to Day 30
3. No further messages sent
4. At Day 30 → Agent session is deleted
5. User sends message at Day 31 → New agent session created with fresh conversation history
### Example 2: TTL reset on interaction
1. Agent configured with 30-day TTL
2. User sends message at Day 0 → agent session created, expiration set to Day 30
3. User sends message at Day 15 → Expiration reset to Day 45
4. User sends message at Day 40 → Expiration reset to Day 70
5. Agent session remains active as long as there are regular interactions
## Logging
The TTL feature includes comprehensive logging to track state changes:
- **Expiration time updated**: Logged when TTL expiration time is set or updated
- **Deletion scheduled**: Logged when a deletion check signal is scheduled
- **Deletion check**: Logged when a deletion check operation runs
- **Session expired**: Logged when an agent session is deleted due to expiration
- **TTL rescheduled**: Logged when a deletion signal is rescheduled
These logs help monitor TTL behavior and troubleshoot any issues.
## Best practices
1. **Choose appropriate TTL values**: Balance between storage costs and user experience. Too short TTLs may delete active sessions, while too long TTLs may accumulate unnecessary state.
2. **Use per-agent TTLs**: Different agents may have different usage patterns. Configure TTLs per-agent based on expected session lifetimes.
3. **Monitor expiration logs**: Review logs to understand TTL behavior and adjust configuration as needed.
4. **Test with short TTLs**: During development, use short TTLs (e.g., minutes) to verify TTL behavior without waiting for long periods.
## Limitations
- TTL is based on wall-clock time, not activity time. The expiration timer starts from the last message timestamp.
- Deletion checks are durably scheduled operations and may have slight delays depending on system load.
- Once an agent session is deleted, its conversation history cannot be recovered.
- TTL deletion requires at least one worker to be available to process the deletion operation message.
This feature ports the vector store abstractions, embedding generator abstractions, and their implementations from Semantic Kernel into Agent Framework. The ported code follows AF's coding standards, feels native to AF, and is structured to allow data models/schemas to be reusable across both frameworks. The embedding abstraction combines the best of SK's `EmbeddingGeneratorBase` and MEAI's `IEmbeddingGenerator<TInput, TEmbedding>`.
- **Both Protocol and Base class** (matching AF's `SupportsChatGetResponse` + `BaseChatClient` pattern):
- `SupportsGetEmbeddings` — Protocol for duck-typing
- `BaseEmbeddingClient` — ABC base class for implementations (similar to `BaseChatClient`)
- **Generic input type** (`EmbeddingInputT`, default `str`) from MEAI — allows image/audio embeddings in the future
- **Generic output type** (`EmbeddingT`, default `list[float]`) from MEAI — supports `list[float]`, `list[int]`, `bytes`, etc.
- **Generic order**: `[EmbeddingInputT, EmbeddingT, EmbeddingOptionsT]` — options last, matching MEAI's `IEmbeddingGenerator<TInput, TEmbedding>` with options appended
- **TypeVar naming convention**: Use `SuffixT` per AF standard (e.g., `EmbeddingInputT`, `EmbeddingT`, `ModelT`, `KeyT`)
- `EmbeddingGenerationOptions` TypedDict (inspired by MEAI, matching AF's `ChatOptions` pattern) — `total=False`, includes `dimensions`, `model_id`. No `additional_properties` since each implementation extends with its own fields.
- Protocol and base class are generic over input, output, and options: `SupportsGetEmbeddings[EmbeddingInputT, EmbeddingT, OptionsContraT]`, `BaseEmbeddingClient[EmbeddingInputT, EmbeddingT, OptionsCoT]`
- **`Embedding[EmbeddingT]` type** in `_types.py` — a lightweight generic class (not Pydantic) with `vector: EmbeddingT`, `model_id: str | None`, `dimensions: int | None` (explicit or computed from vector), `created_at: datetime | None`, `additional_properties: dict[str, Any]`
- **`GeneratedEmbeddings[EmbeddingT, EmbeddingOptionsT]` type** — a list-like container of `Embedding[EmbeddingT]` objects with `options: EmbeddingOptionsT | None` (stores the options used to generate), `usage: dict[str, Any] | None`, `additional_properties: dict[str, Any]`
- **No numpy dependency** — return `list[float]` by default; users cast as needed
### Vector Store Abstractions
- **Port core abstractions without Pydantic for internal classes** — use plain classes
- **Both Protocol and Base class** for vector store operations (matching AF pattern):
- `BaseVectorCollection` / `BaseVectorSearch` — ABC base classes for implementations
- `BaseVectorStore` — ABC base class for store operations (factory for collections, no protocol needed)
- **TypeVar naming convention**: `ModelT`, `KeyT`, `FilterT` (suffix T, per AF standard)
- **Support Pydantic for user-facing data models** — the `@vectorstoremodel` decorator and `VectorStoreCollectionDefinition` should work with Pydantic models, dataclasses, plain classes, and dicts
- `Embedding[EmbeddingT]` generic class: `vector: EmbeddingT`, `model_id: str | None`, `dimensions: int | None` (explicit param or computed from vector length), `created_at: datetime | None`, `additional_properties: dict[str, Any]`
- `GeneratedEmbeddings[EmbeddingT, EmbeddingOptionsT]` generic class: list-like container of `Embedding[EmbeddingT]` objects with `options: EmbeddingOptionsT | None` (the options used to generate), `usage: dict[str, Any] | None`, `additional_properties: dict[str, Any]`
- `EmbeddingGenerationOptions` TypedDict (`total=False`): `dimensions: int`, `model_id: str` — follows the same pattern as `ChatOptions`. No `additional_properties` needed since it's a TypedDict and each implementation can extend with its own fields.
#### 1.2 — Embedding generator protocol + base class in `_clients.py`
- `SupportsGetEmbeddings(Protocol[EmbeddingInputT, EmbeddingT, OptionsContraT])`: generic over input, output, and options (all with defaults), `get_embeddings(values: Sequence[EmbeddingInputT], *, options: OptionsContraT | None = None) -> Awaitable[GeneratedEmbeddings[EmbeddingT]]`
- `BaseEmbeddingClient(ABC, Generic[EmbeddingInputT, EmbeddingT, OptionsCoT])`: ABC base class mirroring `BaseChatClient` pattern
- `__init__` with `additional_properties`, etc.
- Abstract `get_embeddings(...)` for subclasses to implement directly (no `_inner_*` indirection — simpler than chat, no middleware needed)
- `EmbeddingTelemetryLayer` in `observability.py` — MRO-based telemetry (no closure), `gen_ai.operation.name = "embeddings"`
#### 1.3 — OpenAI embedding generator in `agent_framework/openai/` and `agent_framework/azure/`
- `RawOpenAIEmbeddingClient` — implements `get_embeddings` via `_ensure_client()` factory
- `OpenAIEmbeddingClient(OpenAIConfigMixin, EmbeddingTelemetryLayer[str, list[float], OptionsT], RawOpenAIEmbeddingClient[OptionsT])` — full client with config + telemetry layers
- `OpenAIEmbeddingOptions(EmbeddingGenerationOptions)` — extends with `encoding_format`, `user`
- `AzureOpenAIEmbeddingClient` in `agent_framework/azure/` — follows `AzureOpenAIChatClient` pattern with `AzureOpenAIConfigMixin`, `load_settings`, Entra ID credential support
- `AzureOpenAISettings` extended with `embedding_deployment_name` (env var: `AZURE_OPENAI_EMBEDDING_DEPLOYMENT_NAME`)
#### 1.4 — Tests and samples
- Unit tests for types, protocol, base class, OpenAI client, Azure OpenAI client
- Integration tests for OpenAI and Azure OpenAI (gated behind credentials check, `@pytest.mark.flaky`)
- Samples in `samples/02-agents/embeddings/` — `openai_embeddings.py`, `azure_openai_embeddings.py`

### Phase 2: Embedding Generators for Existing Providers
**Goal:** Add embedding generators to all existing AF provider packages that have chat clients.
**Mergeable:** Yes — each is independent, added to existing provider packages.
#### 2.1 — Foundry inference embedding (in `packages/foundry/`)
#### 2.2 — Ollama embedding (in `packages/ollama/`)
#### 2.3 — Anthropic embedding (in `packages/anthropic/`)
#### 2.4 — Bedrock embedding (in `packages/bedrock/`)
---
### Phase 3: Core Vector Store Abstractions
**Goal:** Establish all vector store types, enums, the decorator, collection definition, and base classes.
**Mergeable:** Yes — adds new abstractions, no breaking changes.
#### 3.1 — Vector store enums and field types in `_vectors.py`
- `SerializeMethodProtocol`, `ToDictFunctionProtocol`, `FromDictFunctionProtocol`, etc.
- Port the record handler logic but without Pydantic base class — use plain class or ABC
#### 3.4 — Vector store base classes in `_vectors.py`
- `VectorStoreRecordHandler` — internal base class that handles serialization/deserialization between user data models and store-specific formats, plus embedding generation for vector fields. Both `BaseVectorCollection` and `BaseVectorSearch` extend this.
- `BaseVectorCollection(VectorStoreRecordHandler)` — base for collections
- Uses `SupportsGetEmbeddings` instead of `EmbeddingGeneratorBase`
- Not a Pydantic model — use `__init__` with explicit params
**Mergeable:** Yes — each connector is independent.
#### 6.1 — MongoDB Atlas (`packages/mongodb/`)
#### 6.2 — Azure Cosmos DB (`packages/azure-cosmos-db/`)
- Cosmos Mongo + Cosmos NoSQL
#### 6.3 — Pinecone (`packages/pinecone/`)
#### 6.4 — Chroma (`packages/chroma/`)
#### 6.5 — Weaviate (`packages/weaviate/`)
---
### Phase 7: Vector Store Connectors — Tier 3
**Goal:** Ship niche or less common connectors.
**Mergeable:** Yes — each connector is independent.
#### 7.1 — Oracle (`packages/oracle/`)
#### 7.2 — SQL Server (`packages/sql-server/`)
#### 7.3 — FAISS (`packages/faiss/` or in core extending InMemory)
> **Note:** When implementing any SQL-based connector (PostgreSQL, SQL Server, SQLite, Cosmos DB), review the .NET MEVD changes made by @roji (Shay Rojansky) in SK for design patterns, query building, filter translation, and feature parity: https://github.com/microsoft/semantic-kernel/pulls?q=is%3Apr+author%3Aroji+is%3Aclosed
---
### Phase 8: Vector Store CRUD Tools
**Goal:** Provide a full set of agent-usable tools for CRUD operations on vector store collections.
**Mergeable:** Yes — adds tools without changing existing APIs.
#### 8.1 — `create_upsert_tool` — tool for upserting records into a collection
#### 8.2 — `create_get_tool` — tool for retrieving records by key
- Key-based lookup only (by primary key), not a search tool
- Documentation must clearly distinguish this from `create_search_tool`: get_tool retrieves specific records by their known key, while search_tool performs similarity/filtered search across the collection
- Consider if this overlaps with filtered search and document when to use which
#### 8.3 — `create_delete_tool` — tool for deleting records by key
#### 8.4 — Tests and samples for CRUD tools
---
### Phase 9: Additional Embedding Implementations (New Providers)
**Goal:** Provide embedding generators for providers that don't yet have AF packages.
**Mergeable:** Yes — each is independent, new packages.
#### 9.1 — HuggingFace/ONNX embedding (new package or lab)
#### 9.2 — Mistral AI embedding (new package)
#### 9.3 — Google AI / Vertex AI embedding (new package)
- `create_search_function()` for kernel integration (may need AF equivalent)
#### 10.2 — Brave Search implementation
#### 10.3 — Google Search implementation
#### 10.4 — Vector store text search bridge (connecting VectorSearch to TextSearch interface)

## Key Considerations
1. **No Pydantic for internal classes**: All AF internal classes should use plain classes. Pydantic is only used for user-facing input validation (e.g., vector store data models).
2. **Protocol + Base class**: Follow AF's pattern of both a `Protocol` for duck-typing and a `Base` ABC for implementation, matching how `SupportsChatGetResponse` + `BaseChatClient` works.
3. **Exception hierarchy**: Use AF's `IntegrationException` branch for vector store operations, since vector stores are external dependencies.
4. **`from __future__ import annotations`**: Required in all files per AF coding standard.
5. **No `**kwargs` escape hatches in public APIs**: For user-facing interfaces, use explicit named parameters per AF coding standard. Internal implementation details (e.g., cooperative multiple inheritance / MRO patterns) may use `**kwargs` where necessary, as long as they are not exposed in public signatures.
6. **Lazy loading**: Connector packages use `__getattr__` lazy loading in core provider folders.
7. **Reusable data models**: The `@vectorstoremodel` decorator and `VectorStoreCollectionDefinition` should be agnostic enough to work with both SK and AF. The core types (`FieldTypes`, `IndexKind`, `DistanceFunction`, `VectorStoreField`) should be identical or easily mapped.
8. **`create_search_tool`**: The AF-native equivalent of SK's `create_search_function`. Instead of creating a `KernelFunction`, this creates an AF `FunctionTool` (via the `@tool` decorator pattern) from a vector search. This allows agents to use vector search as a tool during conversations. Design:
- `create_search_tool(name, description, search_type, ...)` → returns a `FunctionTool` that wraps `VectorSearch.search(search_type=...)`
- The tool accepts a query string, performs embedding + vector search, and returns results as strings
- Lives in `_vectors.py` as a method on `BaseVectorSearch` and/or as a standalone factory function
9. **CRUD tools**: A full set of create/read/update/delete tools for vector store collections, allowing agents to manage data in vector stores. Design:
- `create_upsert_tool(...)` → tool for upserting records
- `create_get_tool(...)` → tool for retrieving records by key
- `create_delete_tool(...)` → tool for deleting records
- These are separate from search and are placed in a later phase
10. **Score threshold filtering**: `SearchOptions` includes `score_threshold: float | None` to filter search results by relevance score (ref: [SK .NET PR #13501](https://github.com/microsoft/semantic-kernel/pull/13501)). The semantics depend on the distance function: for similarity functions (cosine similarity, dot product), results *below* the threshold are filtered out; for distance functions (cosine distance, euclidean), results *above* the threshold are filtered out. Use `DISTANCE_FUNCTION_DIRECTION_HELPER` to determine direction. Connectors should implement this natively where the database supports it, falling back to client-side post-filtering otherwise.
dotnet test --project tests/Microsoft.Agents.AI.<Package>.UnitTests
dotnet format src/Microsoft.Agents.AI.<Package>
# Run a single test
# Replace the filter values with the appropriate assembly, namespace, class, and method names for the test you want to run and use * as a wildcard elsewhere, e.g. "/*/*/HttpClientTests/GetAsync_ReturnsSuccessStatusCode"
# Use `--ignore-exit-code 8` to avoid failing the build when no tests are found for some projects
dotnet test --filter-query "/<assemblyFilter>/<namespaceFilter>/<classFilter>/<methodFilter>" --ignore-exit-code 8
# Run unit tests only
# Use `--ignore-exit-code 8` to avoid failing the build when no tests are found for integration test projects
dotnet test --filter-query "/*UnitTests*/*/*/*" --ignore-exit-code 8
```
Use `--tl:off` when building to avoid flickering when running commands in the agent.
## Speeding Up Builds and Testing
The full solution is large. Use these shortcuts:
| Change type | What to do |
|-------------|------------|
| Isolated/Internal logic | Build only the affected project and its `*.UnitTests` project. Fix issues, then build the full solution and run all unit tests. |
| Public API surface | Build the full solution and run all unit tests immediately. |
Example: Building a single code project for all target frameworks
Example: Running tests for a single project using .NET 10.
```bash
# From dotnet/ directory
dotnet test --project ./tests/Microsoft.Agents.AI.Abstractions.UnitTests -f net10.0
```
Example: Running a single test in a specific project using .NET 10.
Provide the full namespace, class name, and method name for the test you want to run:
```bash
# From dotnet/ directory
dotnet test --project ./tests/Microsoft.Agents.AI.Abstractions.UnitTests -f net10.0 --filter-query "/*/Microsoft.Agents.AI.Abstractions.UnitTests/AgentRunOptionsTests/CloningConstructorCopiesProperties"
```
### Multi-target framework tip
Most projects target multiple .NET frameworks. If the affected code does **not** use `#if` directives for framework-specific logic, pass `-f net10.0` to speed up building and testing.
### Package Restore tip
`dotnet build` will try and restore packages for all projects on each build, which can be slow.
Unless packages have been changed, or it's the first time building the solution, add `--no-restore` to the build command to skip this step and speed up builds.
Just remember to run `dotnet restore` after pulling changes, making changes to project references, or when building for the first time.
### Testing on Linux tip
Unit tests target both .NET Framework as well as .NET Core. When running on Linux, only the .NET Core tests can be run, as .NET Framework is not supported on Linux.
To run only the .NET Core tests, use the `-f net10.0` option with `dotnet test`.
### Microsoft Testing Platform (MTP)
Tests use the [Microsoft Testing Platform](https://learn.microsoft.com/dotnet/core/testing/unit-testing-platform-intro) via xUnit v3. Key differences from the legacy VSTest runner:
- **`dotnet test` requires `--project`** to specify a test project directly (positional arguments are no longer supported).
- **Test output** uses the MTP format (e.g., `[✓112/x0/↓0]` progress and `Test run summary: Passed!`).
- **TRX reports** use `--report-xunit-trx` instead of `--logger trx`.
- **Code coverage** uses `Microsoft.Testing.Extensions.CodeCoverage` with `--coverage --coverage-output-format cobertura`.
- **Running a test project directly** is supported via `dotnet run --project <test-project>`. This bypasses the `dotnet test` infrastructure and runs the test executable directly with the MTP command line.
- **Running tests across the solution** with a filter may cause some projects to match zero tests, which MTP treats as a failure (exit code 8). Use `--ignore-exit-code 8` to suppress this:
```bash
# Run all unit tests across the solution, ignoring projects with no matching tests
dotnet test --solution ./agent-framework-dotnet.slnx --no-build -f net10.0 --ignore-exit-code 8
```
- **Running tests with `--solution` for a specific TFM** requires all projects in the solution to support that TFM. Not all projects target every framework (e.g., some are `net10.0`-only). Use `./dotnet/eng/scripts/New-FilteredSolution.ps1` to generate a filtered solution:
```powershell
# Generate a filtered solution for net472 and run tests
# Run tests directly via dotnet run (MTP native command line)
dotnet run --project ./tests/Microsoft.Agents.AI.UnitTests -f net10.0
# Show MTP command line help
dotnet run --project ./tests/Microsoft.Agents.AI.UnitTests -f net10.0 -- -?
```
