Bumps the released 1.6.0 packages agent-framework, agent-framework-core, agent-framework-foundry, and agent-framework-openai to 1.7.0, with root continuing to exactly pin agent-framework-core[all]. Bumps the changed prerelease packages agent-framework-a2a, agent-framework-chatkit, agent-framework-declarative, agent-framework-devui, and agent-framework-foundry-hosting to the 260528 date stamp, raises core floors on the packages included in this release, raises Foundry's OpenAI floor alongside OpenAI, and raises ChatKit's openai-chatkit floor to the minimum version required by the current typed API usage. No beta cohort bump was applied; the absent mistal/mistral package was intentionally not bumped because no such package exists in this branch.
* Python: Allow hosted checkpoints to restore MessageRole
Allow Responses hosting checkpoint storage to deserialize the Azure Responses MessageRole enum that hosted workflows can persist inside Agent Framework Message objects.
Add regression coverage for both direct load() and the hosted get_latest() restore path, including the plain-storage failure mode where list_checkpoints logs the blocked type and get_latest() returns None.
Ruff also normalizes a duplicate contextlib import in the touched hosting module.

`OpenAIChatClient._inner_get_response()` reads `.headers` on the raw streaming
response returned by `client.responses.with_raw_response.create(stream=True)`
(and its three sibling call sites - retrieve-streaming, non-streaming create
and background retrieve) to surface the `x-ms-served-model` Azure header,
introduced in #5910.
When `azure-ai-projects>=2.1.0` experimental GenAI tracing is enabled
(`AZURE_EXPERIMENTAL_ENABLE_GENAI_TRACING=true`), the instrumentor wraps the
raw streaming response in an inline `AsyncStreamWrapper` that exposes
`.response` but not `.headers`. Reading `raw_create_response.headers` then
raises `AttributeError: 'AsyncStreamWrapper' object has no attribute 'headers'`,
which `FoundryChatClient` rethrows as a `ChatClientException` and breaks every
streaming call (workflows and free chat).
Fix: read the header dict via `getattr(raw_response, "headers", None)` at all
four call sites. `_extract_served_model()` already short-circuits on `None`,
so the served-model surfacing degrades gracefully (model stays the deployment
alias) instead of crashing when the response is wrapped by an instrumentor
that does not proxy `.headers`.
Regression test added:
`test_streaming_response_without_headers_attribute_does_not_crash`
simulates a stream wrapper that raises `AttributeError` on `.headers` and
asserts the stream still completes with the deployment alias as `update.model`.

* feat(a2a): link follow-up messages via reference_task_ids
Track the task_id from A2A responses (task, status_update, artifact_update,
and message payloads) on session.state and include it as reference_task_ids
on subsequent outgoing messages. This enables remote agents to correlate
follow-up messages as task refinements per the A2A spec.

* feat(a2a): add A2AAgentSession for typed protocol state tracking
Introduce A2AAgentSession (subclass of AgentSession) with context_id,
task_id, and task_state properties. This follows the DurableAgentSession
pattern and mirrors the .NET A2AAgentSession design.
- Track task_id, context_id, and task_state from all response payload types
- Validate context_id consistency (raise on mismatch)
- Auto-assign server-generated context_id when not set
- Only A2AAgentSession gets reference tracking (no state dict fallback)
- Plain AgentSession continues to work without reference tracking
- Add serialization support (to_dict/from_dict)
- Export via agent_framework.a2a and agent_framework_a2a

* fix: track context_id from message payloads in A2AAgentSession
Previously, context_id was only captured from task, status_update, and
artifact_update payloads. Message-only responses (which carry context_id
but may lack task_id) were silently lost. This fix:
- Captures msg.context_id in the message handler
- Persists session state when either last_task_id or last_context_id is
present (not only when task_id is truthy)
- Only updates task_id/task_state when a task_id was actually returned
- Adds a test for message-only context_id tracking

* Gate status content to INPUT_REQUIRED/terminal states (match .NET)
Match .NET's GetUserInputRequests pattern: only emit TaskStatusUpdateEvent
message content when state is INPUT_REQUIRED or terminal. Intermediate
status text (WORKING, SUBMITTED) is no longer surfaced to callers.
When state is INPUT_REQUIRED, set additional_properties['input_required']
= True so callers can distinguish input requests from final responses.

without task tracking)
- Remove 'or last_task_id' fallback from status_update and
artifact_update handlers (spec guarantees task_id is always set)
- Remove additional_properties['input_required'] flag (content gating
to INPUT_REQUIRED/terminal states is the signal itself)

Fixes#4522
Replace deprecated `asyncio.iscoroutinefunction()` with `inspect.iscoroutinefunction()`
to resolve Python 3.13+ deprecation warning.
Changes:
- Added `import inspect` to imports
- Replaced `asyncio.iscoroutinefunction(hook)` with `inspect.iscoroutinefunction(hook)` on line 126
- This makes the code consistent with other test methods in the same file (lines 201, 236)
The rest of the file already uses `inspect.iscoroutinefunction()` correctly, making
this change consistent with the existing codebase pattern.

* feat(foundry): add experimental to_prompt_agent converter
Adds `to_prompt_agent(agent)`, an experimental converter
(`ExperimentalFeature.TO_PROMPT_AGENT`) that turns an Agent Framework
`Agent` into a Foundry `PromptAgentDefinition` ready to publish via
`AIProjectClient.agents.create_version(...)`.
Behaviour:
* `agent.client` must be a `FoundryChatClient` (or subclass); otherwise
`TypeError` is raised. The model deployment name is lifted from the
bound client so the same Agent definition used for local runs can be
published as a hosted prompt agent without restating the model.
* Foundry SDK tool instances (from `FoundryChatClient.get_*_tool()`) are
passed through unchanged. AF `FunctionTool`s (and `@tool`-decorated
callables) are emitted as Foundry `FunctionTool` declarations.
* Local AF MCP tools cannot be expressed in a `PromptAgentDefinition`;
the converter raises `ValueError` and points at
`FoundryChatClient.get_mcp_tool()` for hosted MCP servers.
* The converter walks both `agent.default_options["tools"]` and
`agent.mcp_tools` because `normalize_tools()` splits local MCP off
into its own list.
Re-exported through the `agent_framework.foundry` lazy-loading namespace
(updates both `__init__.py` and the `__init__.pyi` type stub).
Adds a portable-agent sample showing the same `Agent` driven through
both `agent.run(...)` and `to_prompt_agent(agent)`, and a README section
covering the new converter.

* Construct `PromptAgentDefinition` `Tool` from a dict via `**tool_item`
unpacking rather than the positional Mapping constructor \u2014 cleaner and
matches the typical Pydantic / Azure SDK pattern.
* Drop the redundant `isinstance(mcp_tool, MCPTool)` guard in
`_convert_tools`; the parameter is already typed `Iterable[MCPTool]` so
the second `raise` was unreachable. The remaining single `raise`
fires for every entry as intended.

* fix(foundry): match Agent.__init__ model resolution in to_prompt_agent
* Read the model from `agent.default_options.get("model")` first,
falling back to `agent.client.model`. This mirrors the order
`Agent.__init__` uses (`_agents.py:740`) when assembling
default_options, so the model the agent runs with is the same model
the converter publishes \u2014 e.g. when the caller passes
`default_options={"model": "..."}` to override the bound client.
* Updated the missing-model error message to point at both the client
and the default_options paths.
* Added tests:
* tool-only agent with no `instructions` produces a definition
where `instructions` is `None` and is omitted from the dict
payload (`Agent.__init__` strips None values from default_options
before storing them).
* `default_options['model']` wins over the bound client's model.
* Fallback to client.model when default_options has no model.

* feat(foundry): add deploy_as_prompt_agent helper + samples
Adds `deploy_as_prompt_agent(agent)`, a convenience wrapper around
`to_prompt_agent` that reuses the bound FoundryChatClient's project
client to call `project_client.agents.create_version(...)`. Defaults
`agent_name` / `description` from `agent.name` / `agent.description`
so the Agent stays the single source of truth.
* Exposed from `agent_framework_foundry` and the lazy-loading
`agent_framework.foundry` namespace (including the .pyi stub).
* Marked experimental with the existing
`ExperimentalFeature.TO_PROMPT_AGENT` tag.
* Tests cover the happy path, name/description defaulting, explicit
override, no-name error, metadata + description forwarding, extra
kwargs passthrough, and the experimental metadata.
Samples:
* Renamed the existing sample to `creating_prompt_agents.py`, drops
'portable' wording, presents `deploy_as_prompt_agent` first as the
recommended path and `to_prompt_agent` + `AIProjectClient` as the
two-step alternative, and adds a cleanup step that deletes the
published agent so re-runs stay idempotent.
* New `using_prompt_agents.py` shows the end-to-end loop: deploy the
agent, connect to it with `FoundryAgent` passing the same local
`@tool` callable, run a query against the deployed prompt agent,
then clean up.
README updated to introduce `deploy_as_prompt_agent` as the
recommended path and link to both runnable samples.

(accepted as a keyword argument).
* default_options-sourced (with kwarg overrides):
temperature, top_p, string tool_choice
* kwarg-only Foundry knobs:
reasoning, text, structured_inputs, rai_config, ToolChoiceParam tool_choice
Precedence is always: explicit keyword > default_options entry > unset.
Tests cover every path (defaults, default_options, kwargs, kwarg override).
Samples and README rewritten around the enriched to_prompt_agent.

* refactor(foundry): single source of truth for prompt-agent options
Stop duplicating the generation-parameter surface between FoundryChatOptions
and to_prompt_agent. Translate every field with an Agent Framework equivalent
(temperature, top_p, tool_choice, reasoning, response_format/text/verbosity)
from agent.default_options via a new RawFoundryChatClient helper
_prepare_prompt_agent_options. Only Foundry-specific fields with no AF
equivalent — structured_inputs and rai_config — remain as keyword arguments
on to_prompt_agent.
- tool_choice is dropped when there are no tools (mirrors _prepare_options
semantics and avoids polluting tool-less prompt agents with Agent.__init__'s
'auto' default).
- response_format Pydantic models route through
openai.lib._parsing._responses.type_to_text_format_param; dict shapes go
through the existing _prepare_response_and_text_format helper.
- default_options is not mutated; text dict is defensively copied.

new single-source model.

* refactor(foundry): move _prepare_prompt_agent_options into _to_prompt_agent
Lift the translation helper off RawFoundryChatClient and into the
_to_prompt_agent module as a module-private function that takes the client
as its first argument. The chat client no longer needs to carry a method
whose only consumer is the prompt-agent converter, while still serving as
the source of the request-path helper (_prepare_response_and_text_format)
that the converter reuses for dict-shaped response_format values.

* docs(python): codify GA terminology + post-run docs review
Add two pieces of guidance to python/AGENTS.md:
* Terminology - reserve 'GA' for hosted services; use 'released' or 'stable'
for Agent Framework code/features to match the feature-lifecycle stages.
* Maintaining Documentation - review AGENTS.md and skills at the end of every
run and update any guidance the conversation made stale; before adding a
new principle, ask the user to confirm it should be captured.
Also pulls in a docstring fix in foundry_prompt_agents.py that swaps the
stray 'GA' for 'released', applying the new terminology rule.
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* address PR review: strict=True default, Tool._deserialize dispatch, sample cleanup safety
- FunctionTool published as strict=True so the server-side schema validation
matches what the local FoundryAgent(tools=[same_callable]) dispatcher
enforces. AF FunctionTool has no 'strict' attribute, so the safer default
is used uniformly instead of silently downgrading to a permissive contract.
- _validate_mapping_tool now dispatches through ProjectsTool._deserialize so
dict-shaped tools rehydrate to the concrete subclass (FunctionTool,
WebSearchTool, ...) via the 'type' discriminator instead of returning a
generic Tool. Added a test that asserts isinstance(WebSearchTool) and a
new test for the function-typed dict path.
- foundry_prompt_agents.py sample now wraps credential + project client in
async with and the create_version / run flow in try/finally so a failure
on connect or run still deletes the published prompt agent rather than
leaving an orphaned, billable resource in the user's Foundry project.

GitHub PR URLs use the singular segment /pull/N (compare to /issues/N

* Add Python parity sample for invoking Foundry Toolbox tools from declarative workflows
* Python: address PR review on declarative toolbox sample
Two security fixes for PR #5933:
1. Add safe_mode flag to WorkflowFactory (default True) mirroring
AgentFactory. Gates =Env.* exposure inside DeclarativeWorkflowState
PowerFx symbols via _safe_mode_context, so workflow YAML loaded from
untrusted sources no longer leaks the host's full os.environ snapshot
into PowerFx evaluation. The flag is also forwarded to the
internally-constructed AgentFactory so inline agent definitions
follow the same policy.
2. Pin the invoke_foundry_toolbox_mcp sample's _client_provider to the
resolved toolbox endpoint. The bearer-authenticated httpx client is
now only returned when MCPToolInvocation.server_url matches the
toolbox URL case-insensitively; any other URL gets None (the default
unauthenticated path), preventing the Foundry AAD bearer token from
being attached to a mis-configured or injected server URL. Mirrors
the .NET sample's httpClientProvider guard.
The sample is updated to opt in to safe_mode=False because its YAML
intentionally uses =Env.FOUNDRY_TOOLBOX_* to keep configuration in env
vars under the developer's control.

* .NET: Refactor AgentSkill API to async resource and script lookup
Replace property-based AgentSkill.Content, Resources, and Scripts with
async-by-name lookup methods plus boolean availability flags:
- Content (string getter) -> GetContentAsync(CancellationToken)
- Resources (full list) -> HasResources + GetResourceAsync(name, ct)
- Scripts (full list) -> HasScripts + GetScriptAsync(name, ct)
This makes the API friendlier for sources like MCP where enumerating all
resources up front is expensive or impossible, and allows skill implementations
to fetch content lazily.
Subclass changes:
- AgentFileSkill and AgentInlineSkill implement the new async API while
preserving content caching.
- AgentClassSkill<TSelf> keeps virtual Resources/Scripts properties for
reflection-based discovery and seals the new HasResources/HasScripts/
GetResourceAsync/GetScriptAsync overrides. Its previously non-thread-safe
lazy initialization is replaced with Lazy<T> (default thread-safety) wired
up in a new protected constructor, so concurrent first-access from multiple
threads is safe.
- AgentSkillsProvider calls the new async API and exposes
ead_skill_resource
/ load_skill /
un_skill_script tools that await the per-name lookups.
Includes baseline CompatibilitySuppressions.xml entries for the removed
property getters.
Tests:
- Direct coverage for HasResources, HasScripts, GetResourceAsync, and
GetScriptAsync on all three skill implementations (positive, missing-name,
and no-resources/no-scripts cases).
- Thread-safety regression test for AgentClassSkill<TSelf> that exercises
concurrent first-access to Resources, Scripts, and GetContentAsync from
many tasks and asserts all observers see the same cached instance.
- Provider-level coverage for the
ead_skill_resource tool (invocation +
error paths) and for the previously untested error paths of load_skill
and
un_skill_script (empty names, skill/resource/script not found).

Fix three interlocked bugs that prevent parallel tool calls from rendering
correctly in AG-UI protocol clients:
Bug #1: Scope synthetic MessageId fallback to text events only. The shared
streamingMessageId was leaking into ToolCallStartEvent.ParentMessageId,
causing all parallel tool calls to collapse into one FE card.
Bug #2: Make ToolCallResultEvent.MessageId deterministically unique using
result-{CallId} format. MEAI's FunctionInvokingChatClient batches all
results with a shared MessageId, collapsing them in FE reconciliation.
Bug #3: Coalesce consecutive assistant-tool-call messages in AsChatMessages.
Once Bug #1 is fixed, the FE produces separate AGUIAssistantMessage per
tool call. On multi-turn replay these become consecutive assistant messages
without intervening tool results, triggering HTTP 400 from Azure OpenAI.
Remove the now-dead ContainsToolResult helper introduced by PR #5800.

When A2AAgent receives a TaskStatusUpdateEvent during streaming,
ConvertToAgentResponseUpdate now sets AgentResponseUpdate.MessageId
from Status.Message.MessageId when the message is present.
This fixes the missing message correlation metadata reported in
microsoft/agent-framework#4987.

* fix(core): point @experimental warnings at user code, not stdlib internals
Previously the wrappers installed by @experimental called warnings.warn
with a fixed stacklevel=3. ABCMeta inserts an extra abc.__new__ frame
when an experimental ABC is subclassed, so the warning landed inside
abc.py (or <frozen abc>:106 on modern CPython) instead of the user's
class Sub(...) line.
Resolve the user frame by walking inspect.currentframe(), skipping
frames whose module name is abc/functools/typing/contextlib (or
submodules), then emit via warnings.warn_explicit so the recorded
filename/lineno point at user code. Falls back to warnings.warn with
stacklevel=2 if no user frame is found. Module-name matching is used
because frozen stdlib modules report '<frozen abc>' as their filename.
Also install a one-line warnings.formatwarning specifically for
FeatureStageWarning so 'file:line: ExperimentalWarning: [ID] Name ...'
prints without the secondary source-snippet line. Other categories
delegate to the stdlib default formatter unchanged.
Added a regression test that subclasses an @experimental ABC inside
warnings.catch_warnings and asserts the recorded filename equals the
test file.

* fix(core): address review feedback on @experimental warning fix
- Make _install_feature_stage_formatter idempotent: tag the installed
formatter with a marker attribute and short-circuit re-installation,
so re-imports/reloads don't wrap the formatter on top of itself.
Also expose the previous formatter via __wrapped__ for restoration.
- Avoid leaking frame references in _resolve_user_frame: capture data
into plain locals inside try and del frame/candidate in finally,
per CPython's guidance on inspect.currentframe usage.
- Drop redundant _WARNED_FEATURES.clear() in the new ABC subclass test
(the autouse fixture already handles it).

* Fix declarative workflow regressions for hosted agents
Three regressions surfaced when running a declarative workflow as a
Foundry hosted agent. Together they caused every condition group to fall
through to elseActions and the raw agent JSON to leak to the caller.
1. AgentProviderExtensions.InvokeAgentAsync forced autoSend to true
whenever the agent ran on the workflow conversation, which overrode
the explicit autoSend: false declared in workflow.yaml and streamed
the raw structured-output JSON straight to the user. Honor the
caller-supplied autoSend instead.
2. IWorkflowContextExtensions.ReadState / QueueStateUpdateAsync /
QueueStateResetAsync took the variable name and namespace alias
directly from PropertyPath.VariableName / NamespaceAlias. Against
Microsoft.Agents.ObjectModel 2026.2.4.1 those properties return null
for a dotted reference such as `Local.Triage` even when
SegmentCount == 2 and IsValid == true, so every assignment threw
ArgumentNullException via Throw.IfNull. Fall back to Segments() to
reconstruct the name and alias when the parser returns null.
3. The same ObjectModel version no longer recognizes the user-facing
`Local` scope alias: VariableScopeNames.IsValidName(`Local`)
returns false and GetNamespaceFromName(`Local`) returns Unknown, so
the declarative interpreter's IsManagedScope check fails and the
State.Set call is silently skipped. Translate the `Local` alias to
its canonical `Topic` form before forwarding to
QueueStateUpdateAsync; WorkflowFormulaState.Bind continues to expose
it as `Local` to PowerFx.
Verified end-to-end against a deployed Foundry hosted agent: the
declarative triage workflow now routes Technical / Billing / General
inputs correctly and only the autoSend-eligible messages reach the
caller.

* Hosted-agent HITL: persist session across previous_response_id chains; run approved local AIFunctions
Two regressions hit declarative workflows that use require_approval=true when
the client chains turns via previous_response_id (no conversation_id):
1. AgentFrameworkResponseHandler keyed the AgentSession store solely on
conversation_id, so when only previous_response_id was present the
StateBag (which holds ToolApprovalIdMap) was discarded after each turn.
The next turn then threw 'No approval mapping recorded for wire id ...'
in InputConverter.ConvertMcpApprovalResponse.
Fix: fall back to previous_response_id on load and to context.ResponseId
on save so the response-id chain becomes a valid session key. Conversation
id remains preferred when present.
2. InvokeFunctionToolExecutor.CaptureResponseAsync only acted on
FunctionResultContent. In the hosted Foundry path the approval response
arrives as a ToolApprovalResponseContent with no FunctionResultContent,
so the local AIFunction never ran and downstream PropertyPath/SendActivity
consumers (e.g. {Local.RefundResult}) saw empty values.
Fix: when no FunctionResultContent matches but an approved
ToolApprovalResponseContent does, look up the registered AIFunction by
name on agentProvider.Functions and invoke it with the evaluated
arguments, surfacing the result through the existing assignment path.

* Apply PropertyPath workaround to initialization path; share + tidy helpers
Address PR #5905 review feedback:
* Move the PropertyPath VariableName/NamespaceAlias fallback and 'Local'
-> 'Topic' scope remap into a shared internal PropertyPathExtensions
helper. Materializes Segments() once, names the magic 'Local' alias
as a const, and carries a TODO referencing the tracking issue.
* Apply the same helper in WorkflowDiagnostics.InitializeDefaults so a
declared default for a dotted variable like 'Local.Triage' is no
longer silently skipped at workflow startup (closes the gap flagged
by the reviewer: runtime ReadState/QueueStateUpdateAsync worked but
state.Initialize did not).
* Restore the previous strict failure mode on namespace alias by
wrapping GetNamespaceAlias() in Throw.IfNull at call sites so a
malformed single-segment path keeps failing fast rather than
silently passing null to State.Get/Set.
All 821 unit tests pass.

* Add tests for AgentProviderExtensions.InvokeAgentAsync autoSend behavior
Covers the autoSend regression fix: when the agent runs on the workflow conversation with autoSend=false, no AgentResponseUpdateEvent or AgentResponseEvent is added to the context. Also covers autoSend=true (events emitted) and autoSend=false on a non-workflow conversation.

* Surface SendActivity output via AgentResponseUpdateEvent
SendActivityExecutor previously only emitted the activity text via YieldOutputAsync, which the runtime converts to an AgentResponseEvent. WorkflowSession gates AgentResponseEvent behind includeWorkflowOutputsInResponse, so when a host opts out of summary outputs (the default for AsAIAgent) the SendActivity reply is silently dropped.
Mirror the pattern used by AgentProviderExtensions for autoSend agent invocations: also emit an AgentResponseUpdateEvent, which WorkflowSession yields unconditionally. This makes SendActivity reliably reach chat-protocol clients without requiring includeWorkflowOutputsInResponse = true (which would also duplicate autoSend agent output).

* Revert previous_response_id session-key fallback
The fallback let a session be keyed by an unbroken previous_response_id chain,
but conversation_id is the right way to thread state across turns: it survives
shared/branched chains (e.g. when another agent generates a response in between)
and is the documented model for stateful clients. Restore conversation_id as the
sole session key and rely on the client to thread it. The InvokeFunctionTool
approval/local-function half of 1baf4af4d remains.

* Set Foundry ProductContext per-executor instead of via PropertyPath workaround
ObjectModel 2026.2.4.1 resolves PropertyPath.VariableName / NamespaceAlias and VariableScopeNames.IsValidName against AsyncLocal<ProductContext> at access time. In hosted-agent scenarios each HTTP request runs on a fresh async context where that AsyncLocal is default, so dotted refs like Local.Triage returned null and the Local scope alias was rejected.
Replace the PropertyPathExtensions helper (which papered over both symptoms) with a single WorkflowDiagnostics.SetFoundryProduct() call at the entry of DeclarativeActionExecutor.HandleAsync. The set writes to the request's logical async context before any code reads PropertyPath, letting the existing parser and scope resolver work as designed.
Validated: 824/824 declarative unit tests pass; technical/billing/general routes all dispatch correctly against a deployed Foundry hosted agent.

* Address review feedback on InvokeFunctionToolExecutor
- Surface registered-function lookup failures and invocation exceptions via FunctionResultContent.Exception instead of returning the error text as a successful Result, so downstream {Local.X} assignments can distinguish failures from successes.
- Use AIJsonUtilities.DefaultOptions to JSON-serialize non-string function results (matching FunctionInvokingChatClient / ToolBridge), so complex types stay consumable by PropertyPath consumers instead of degrading to Object.ToString().
- Drop the explicit System. prefix on StringComparison / Exception now that the file imports System.
- Add AutoSendTrueOnExternalConversationEmitsResponseEventsAndCopiesMessagesAsync to cover the (autoSend: true, external conversation) quadrant, asserting that response events are emitted and that messages are mirrored to the workflow conversation.

* Honor AutoSendIsDefaultValue when computing autoSend
AzureAgentOutput.AutoSend and InvokeToolOutput.AutoSend in
Microsoft.Agents.ObjectModel 2026.2.4.1 are never null — they
return a literal-false default when the YAML omits the field.
The previous null check in Get/AutoSendValue therefore always
fell through to evaluating the literal false, so every action
whose YAML had any output block but no explicit autoSend was
treated as autoSend = false. This was previously masked by
`autoSend |= isWorkflowConversation` in AgentProviderExtensions
(removed earlier in this PR to honor explicit autoSend: false),
which silently re-enabled autoSend on the workflow conversation.
Use AutoSendIsDefaultValue to distinguish an explicit autoSend
value from the implicit default and treat the implicit default
as true, restoring the historical behavior for ValidateCaseAsync
InvokeAgent.yaml (3 InvokeAzureAgent actions, last one captures
to Local.RatingResponse via output.messages with no autoSend
specified) while keeping the hosted-agent fix that honors an
explicit autoSend: false.

* feat(tools): add cross-OS LocalShellTool in new agent-framework-tools package
Introduces a safe, cross-OS local shell tool as the first citizen of a new
agent-framework-tools workspace package. Supports persistent (default) and
stateless modes across pwsh/powershell.exe/bash/sh, with policy denylist,
allowlist, approval gating, process-tree kill on timeout, output truncation,
and audit hooks. Integrates with existing provider get_shell_tool(func=...)
factories via FunctionTool kind='shell'.

* feat(tools): security hardening for LocalShellTool
Codifies what LocalShellTool does and does not defend against, and
delegates the security-relevant lifecycle primitive to a battle-tested
library instead of hand-rolled per-OS code.
Changes:
- Adopt psutil for cross-OS process-tree termination (executor + session).
Replaces hand-rolled taskkill/killpg with one canonical implementation.
- Resolve taskkill.exe to absolute %SystemRoot%\System32 path so PATH
poisoning cannot redirect us to an attacker-supplied binary.
- Reframe ShellPolicy docstring + ADR + README: denylist is a guardrail,
not a security boundary.
- Require acknowledge_unsafe=True to set approval_mode='never_require',
making the unsafe path explicitly opt-in with a self-documenting name.
- Add tests/test_security.py codifying named CVE-style cases. Defenses
we DO claim are asserted; non-defenses (denylist bypasses via
backslash insertion, variable expansion, interpreter escape, base64,
alternative tools, PowerShell-native verbs) are documented as
expected-to-pass tests so residual risk stays visible.
- Add Threat Model + Confidence Strategy sections to ADR 0026.

* feat(tools): add DockerShellTool sandboxed shell tier
Adds a container-backed shell executor as the recommended pattern for untrusted-input shell workflows. The container provides the security boundary (--network none, non-root user, --read-only, --cap-drop ALL, no-new-privileges, memory/pids limits, tmpfs /tmp), so approval gating is optional unlike LocalShellTool.
Also introduces a ShellExecutor Protocol so callers can plug in custom backends (Firecracker, SSH, WASI) without forking the framework.
Removes the planned HyperlightShellExecutor follow-up from ADR 0026: Hyperlight is a WASM code sandbox with no kernel/userland/shell binary, so a Hyperlight-backed shell is not viable. Docker is the realistic sandbox tier for shell.
Tests: 11 unit tests for argv builders + lifecycle (no Docker daemon required); 3 integration tests gated on is_docker_available().

* fix(tools): backport shell-tool fixes from .NET parity review
Applies the applicable subset of bug fixes accumulated during the
.NET shell-tool PR review (microsoft/agent-framework#5604) to the
Python shell tool.
A1 - Quote workdir safely in _maybe_reanchor
Previously _tool.py used double-quote interpolation when emitting
the cd/Set-Location prefix, which expanded $VAR, $(), and backticks
in the workdir path. A workdir containing shell metacharacters could
trigger arbitrary command execution before the user command ran.
Replaced with single-quote escaping helpers _quote_posix and
_quote_powershell that emit literal-string forms safe for both
hosts.
A5/A6 - Consolidate truncation to a single byte-aware helper
Extracted a shared truncate_head_tail / truncate_text_head_tail
helper in _truncate.py. The new implementation distributes odd
caps so head receives floor(cap/2) and tail receives ceil(cap/2)
bytes, matching the .NET round-9 fix and ensuring no input bytes
are silently dropped on the boundary.
_session.py previously truncated by Python str length while the
caller passed _max_output_bytes - the unit mismatch is now gone:
raw byte buffers go through truncate_head_tail and decoded text
goes through truncate_text_head_tail.
Unit tests added for the truncate and quote helpers.

* docs(tools): tone down narrative and overconfident comments in shell tool
The shell tool's docstrings and comments contained two patterns that
the .NET review pushed back on:
- Narrative framing about implementation history ("hard-won",
"we sidestep", "design inspiration: ...", competitor framework
name-drops in module docstrings).
- Overstated security guarantees ("battle-tested",
"reasonable for untrusted input", "recommended executor for any
agent that runs commands from untrusted input",
"destructive commands are blocked", "safe local shell tool",
"blocks shell injection").
Rewrites the affected docstrings and comments to describe what the
code does in neutral terms. Behaviour is unchanged.

* feat(tools): add ShellEnvironmentProvider for the Python shell tool
Ports the .NET ShellEnvironmentProvider as a Python ContextProvider
so agents using LocalShellTool or DockerShellTool can be primed with
an accurate description of the shell they're talking to (family,
version, OS, working directory, and which CLIs are available).
The provider runs probes through any ShellExecutor, caches the
resulting snapshot, and on every before_run extends the session
instructions with a markdown block describing the shell idiom to
use. A failed first probe leaves the cache empty so the next call
retries (no permanent poisoning).
Probe failures from a narrow set of expected error types
(ShellCommandError, ShellExecutionError, ShellTimeoutError, and
asyncio.TimeoutError from the per-probe timeout) are recorded as
None fields in the snapshot. Other exceptions propagate. Tool
names are validated against ^[A-Za-z0-9._-]+$ before being
interpolated into a probe command.
Includes 12 unit tests covering happy path, stderr fallback,
timeout handling, expected/unexpected exception paths, malicious
tool name rejection, case-insensitive deduplication, retry after
failure, concurrent first-callers sharing one probe, and the
default and custom formatter paths.

* docs(tools): document ShellEnvironmentProvider and finish comment cleanup

* refactor(tools): move shell samples to python/samples/02-agents/tools
The repository convention is to host samples under python/samples/ rather than inside the package directory. Move the two net-new shell samples (allow-list and environment-provider) to python/samples/02-agents/tools/ and drop the in-package samples/ directory; the existing top-level providers/openai/client_with_local_shell.py already covers the basic LocalShellTool walkthrough.

* test(tools): cover confine_workdir default and ShellResult.format_for_model
Two new tests in test_local_shell_tool.py exercise the default confine_workdir=True behaviour on POSIX and PowerShell, asserting that 'cd' inside one persistent-mode call does not leak into the next. A new test_shell_result.py module provides direct unit coverage for every conditional branch of ShellResult.format_for_model (stdout, truncated, stderr, timed_out, exit_code) so regressions in the LLM-facing format are caught immediately.

* Remove DEFAULT_DENYLIST; document single-session ownership; fix bandit findings
Mirrors the .NET PR #5604 cleanup:
- Remove DEFAULT_DENYLIST from ShellPolicy. ShellPolicy() now ships with an empty deny-list; operators opt into site-specific patterns explicitly. No major agent framework uses regex matching as a primary security control; AutoGen v2 removed theirs. Approval gating + sandbox tier remain the real boundaries.
- Rewrite module / class docstrings to frame ShellPolicy as a UX pre-filter, not a security control.
- Add Single-session ownership paragraphs to ShellExecutor, ShellSession, LocalShellTool, and DockerShellTool: a persistent-mode tool is owned by exactly one conversation / agent session; do not share across users or concurrent conversations.
- Tests now supply explicit deny patterns instead of relying on a default.
- Address Pre-commit Hooks (bandit) CI failures: convert internal-invariant asserts to explicit RuntimeError, annotate intentional subprocess/shell usage with # nosec, document container-internal /tmp paths.

* Address PR #5664 round-2 review feedback
Deny-list documentation drift:
- README and the OpenAI/local-shell sample no longer claim a built-in deny-list of destructive commands. ShellPolicy is described as an optional, operator-supplied UX pre-filter; the real boundaries remain approval gating and the sandbox tier.
Behavioural fixes called out in review:
- ShellPolicy.evaluate() now denies empty / whitespace-only commands explicitly instead of returning allow with no rationale.
- truncate_head_tail() raises ValueError for cap <= 0 instead of silently returning the full input with truncated=False, which previously could defeat output-capping in callers that mis-configured the budget.
- LocalShellTool.as_function() / DockerShellTool.as_function() return the ShellCommandError text directly so the model sees a single, non-redundant 'Command rejected by policy: …' message instead of the prior duplicated 'Command blocked by policy: Command rejected …' wrapping.
- ShellSession POSIX sentinel trailer now snapshots and restores the prior errexit (set -e) state around the trailer, so a user 'set -e' in the persistent shell is no longer permanently disabled by the next run().
Tests:
- New test_shell_parse_rc.py covers the full _parse_rc() edge-case surface (zero, positive, negative, CRLF, no newline, missing prefix, empty input, non-digits, trailing garbage, partial digits).
- test_policy.py asserts the new empty-command deny.
- test_shell_truncate_and_quote.py asserts ValueError for cap=0 and cap<0.

- _resolve.py: in stateless mode, ensure shell overrides end with -c/-Command so commands aren't misinterpreted as script-file paths.
- ShellExecutor.run / LocalShellTool.run / DockerShellTool.run now accept an optional imeout kwarg; ShellEnvironmentProvider drops the outer asyncio.wait_for and lets the executor enforce the probe timeout internally, so cancellation no longer risks leaving a hung subprocess or corrupted session.

- pyproject.toml: bump agent-framework-core minimum from 1.2.0 to 1.2.2 to align with the rest of the workspace.

- _docker._stop_container: retry docker rm -f once and log a warning/error when it does not succeed, so operators can audit leaked containers instead of getting a silent success.
- _docker._run_stateless timeout path: fall back to docker rm -f when docker kill fails or times out (--rm only reaps on clean exit), and log instead of silently swallowing communicate() errors.

* .NET: Surface x-ms-served-model header as ChatResponse.ModelId for Foundry agents
Mirrors Python PR #5910. Adds an internal SCM PipelinePolicy that reads the x-ms-served-model HTTP response header on Azure OpenAI Responses calls and writes it into an AsyncLocal box. A DelegatingChatClient sits between OpenTelemetry and the MEAI OpenAIResponsesChatClient and overwrites ChatResponse.ModelId with the served snapshot so OTel spans report the actual model rather than the deployment alias. Wired through all AsAIAgent paths in Microsoft.Agents.AI.Foundry.
* .NET: Fix line endings and BOM on ResponsesAgentServedModelTests
* .NET: Address Copilot review on Foundry served-model PR
- Restore previous ServedModelScope in finally to avoid AsyncLocal leak into caller execution context.
- Make served-model integration test assertion robust to deployment names that already match the snapshot pattern.
- Broaden UnitTests csproj comment to cover all conditional removals (net8.0+ requirement).
* .NET: Split ServedModelTests into per-SUT files with regions
Split the combined ServedModelTests.cs into one test class per SUT:
- ServedModelScopeTests.cs (AsyncLocal carrier)
- ServedModelPolicyTests.cs (SCM pipeline policy)
- ServedModelChatClientTests.cs (delegating client, with regions for Non-streaming / Streaming / End-to-end)
Shared helpers and fake clients moved into ServedModelTestHelpers.cs.
Csproj net8.0+ exclusion list updated accordingly.
* .NET: Consolidate served-model logic into FoundryChatClient
Move x-ms-served-model header capture from the standalone ServedModelChatClient
decorator directly into FoundryChatClient, eliminating a separate wrapper that
had to be applied at every Foundry entry point via WireServedModel().
- Register ServedModelPolicy in FoundryChatClient constructors (alongside the
existing AgentFrameworkUserAgentPolicy registration)
- Add StrongBox push/read logic to FoundryChatClient.GetResponseAsync and
GetStreamingResponseAsync
- Delete ServedModelChatClient.cs and its unit tests
- Remove WireServedModel() from FoundryAgent and AIProjectClientExtensions
- Update ServedModelPolicy/Scope XML docs to reference FoundryChatClient
- Simplify ServedModelTestHelpers to use FoundryChatClient directly

* feat(a2a): use non-streaming transport and return_immediately for background ops
When stream=False, use a client configured with streaming=False so the
SDK sends a single HTTP POST to message/send instead of opening an SSE
connection via message/stream. This matches the A2A protocol's design:
non-streaming calls use direct request/response, streaming calls use
Server-Sent Events.
Also sets return_immediately=background on SendMessageConfiguration so
the server respects the caller's intent for background operations.
Changes:
- Create separate streaming and non-streaming internal clients (sharing
the same httpx connection pool) to match protocol transport semantics
- Select non-streaming client for run(stream=False) calls
- Add SendMessageConfiguration with return_immediately=background
- Fallback to streaming client when non-streaming unavailable (e.g. user
provides their own client via constructor)
- Add tests for client selection and return_immediately behavior

* fix: address PR review feedback
- Initialize last_request in MockA2AClient.__init__ for explicit state
- Use 'is not None' instead of truthiness for _non_streaming_client check
- Assert return_immediately propagates through non-streaming client path

* fix: only set configuration when background=True
Only attach SendMessageConfiguration to the request when background=True,
keeping requests minimal and preserving server-side defaults for normal
(foreground) operations. This follows the framework pattern of only
setting optional fields when they have meaningful values.

* fix: only set return_immediately for non-streaming background ops
Per the A2A spec, return_immediately only applies to message/send
(non-streaming). It has no effect on streaming operations. Only set
the configuration field when both background=True and stream=False.
Adds test verifying streaming+background does not set return_immediately.

* Consolidate Foundry chat client decorators into FoundryChatClient
- Replace AzureAIProjectChatClient and AzureAIProjectResponsesChatClient with a single internal sealed FoundryChatClient that covers three modes (pure responses, server-side agent reference, hosted agent endpoint).
- Rename AzureAIProjectChatClientExtensions to AIProjectClientExtensions to reflect that it extends AIProjectClient.
- All four AsAIAgent extension overloads and both FoundryAgent constructors now construct FoundryChatClient internally so the microsoft.foundry telemetry tag is uniform across paths.
- Introduce AgentFrameworkUserAgentPolicy that stamps agent-framework-dotnet/{version} on outbound requests, mirroring the Python agent-framework-python/{version} contract.
- Delete the Foundry-local MeaiUserAgentPolicy duplicate; rely on MEAI 10.5.1 to stamp MEAI/{version} automatically.
- HostedAgentUserAgentPolicy keeps the combined foundry-hosting/agent-framework-dotnet/{version} segment (Python parity) and upgrades the bare segment in place to avoid duplication.
- Tests reorganized: FoundryChatClientTests, AIProjectClientExtensionsTests, AgentFrameworkUserAgentPolicyTests, MeaiAutoUserAgentVerificationTests, plus in-place upgrade unit tests in HostedOutboundUserAgentTests.
* Promote FoundryChatClient to public; add file/vector-store helpers and ToPromptAgentAsync converter
- Promote FoundryChatClient from internal sealed to public sealed for Python parity, so .NET developers can hold and pass a FoundryChatClient directly the way Python developers do.
- Mode 3 (hosted agent endpoint) now materializes an AIProjectClient from the parsed project root, making GetService<AIProjectClient>() non-null across all three construction modes. This eliminates the per-mode asymmetry that previously hid project-level helpers from agents constructed via an agent endpoint URL.
- Add four new instance methods on FoundryChatClient mirroring Python's spec: UploadFileAsync, DeleteFileAsync, CreateVectorStoreAsync (bundles upload + create + wait), DeleteVectorStoreAsync. Single overload each, path-only inputs to start; additional overloads can be added later without breaking callers. All are Experimental, consistent with the rest of the Foundry package.
- Add ToPromptAgentAsync extension methods on ChatClientAgent and FoundryAgent for the agent-to-prompt-agent converter described in the Foundry spec. Mode 1 (responses API) synthesizes a DeclarativeAgentDefinition from the agent's ChatOptions; mode 2 (server-side agent reference, version, or record) returns the cached or freshly fetched Definition; mode 3 throws InvalidOperationException because no local definition exists to convert.
- Strict AITool to ResponseTool mapping for mode 1: AIFunction becomes CreateFunctionTool with the function's JSON schema; AITool instances that wrap a ResponseTool unwrap via GetService(typeof(ResponseTool)); anything else throws InvalidOperationException naming the offending tool type. Matches the Python spec's unsupported-tools-raise-ValueError contract.
- New unit tests: FoundryChatClientVectorStoreTests (22 tests covering all four helpers across the three FoundryChatClient construction modes plus validation and cancellation), FoundryPromptAgentConverterTests (16 tests covering both extension entry points across mode 1 synthesis, mode 2 cached and fetched paths, all failure modes, and a Python-parity guard asserting both extensions produce equivalent definitions for equivalent inputs), plus four new tests in FoundryChatClientTests for the mode 3 AIProjectClient materialization.
* Stop building duplicate ProjectOpenAIClient in FoundryAgent agent-endpoint ctor
After Plan #2's mode-3 AIProjectClient materialization, the inner FoundryChatClient already exposes a project-level AIProjectClient (via GetService) that internally provides the project-level ProjectOpenAIClient via GetProjectOpenAIClient(). FoundryAgent's agent-endpoint constructor was still independently constructing a second project-level ProjectOpenAIClient via the now-redundant CreateProjectLevelOpenAIClientFromAgentEndpoint helper — two handles to the same logical resource.
Refactor: the agent-endpoint constructor now reads the inner FoundryChatClient's materialized AIProjectClient via base.GetService(typeof(AIProjectClient)) and derives the project-level ProjectOpenAIClient from it. The dead helper on both FoundryAgent (private static wrapper) and FoundryChatClient (the actual implementation) is removed. The user-supplied per-agent ClientPipelineOptions primitives (Transport, RetryPolicy, NetworkTimeout, UserAgentApplicationId) are propagated into the materialized AIProjectClientOptions so test-injected transports and explicit retry / timeout / user-agent settings reach the project-level pipeline — preserving the behavior the dead helper used to provide.
Updated AgentEndpointConstructor_GetServiceAIProjectClient_ReturnsNull to its now-correct counterpart AgentEndpointConstructor_GetServiceAIProjectClient_ReturnsNonNull, since after Plan #2 the agent-endpoint ctor surfaces a non-null AIProjectClient (per user direction in Plan #2 Q2).
* Strip duplicated AIProjectClient/ProjectOpenAIClient state from FoundryAgent
Both _aiProjectClient and _projectOpenAIClient fields on FoundryAgent were redundant:
- _aiProjectClient: FoundryAgent's GetService<AIProjectClient> override returned this field, but DelegatingAIAgent.GetService → ChatClientAgent.GetService → FoundryChatClient.GetService<AIProjectClient> already returns the same instance through the delegating chain. Field + override are pure duplication.
- _projectOpenAIClient: only used by FoundryAgent's own GetService<ProjectOpenAIClient> override and by CreateConversationSessionAsync. Per user direction, ProjectOpenAIClient is no longer exposed via GetService on either FoundryChatClient or FoundryAgent — callers retrieve it from the AIProjectClient themselves (aiProjectClient.GetProjectOpenAIClient()) the same way the framework does internally. This eliminates the mode-3 asymmetry where the chat client's stored ProjectOpenAIClient was per-agent (URL /agents/{name}/endpoint/protocols/openai) while the agent's was project-level.
Refactor:
- Delete both fields on FoundryAgent and the GetService override.
- Delete the ProjectOpenAIClient branch from FoundryChatClient.GetService.
- CreateConversationSessionAsync now resolves AIProjectClient at call time via this.GetService<AIProjectClient>() and derives the conversations client from it.
- Update FoundryChatClient tests that asserted on GetService<ProjectOpenAIClient> to assert Null (deliberate removal).
- Update FoundryAgent tests AgentEndpointConstructor_GetServiceProjectOpenAIClient_ReturnsNonNull and ProjectEndpointConstructor_GetServiceProjectOpenAIClient_ReturnsNonNull to ...ReturnsNull, and rewrite AgentEndpointConstructor_PropagatesUserAgentApplicationId_ToProjectLevelClient to look up AIProjectClient instead.
No production code (only tests) referenced GetService<ProjectOpenAIClient>, so this is a safe surface reduction. Net: 30 insertions, 61 deletions; FoundryAgent shrinks to a pure delegator with only the two convenience methods (CreateSessionAsync, CreateConversationSessionAsync) on top of the delegating chain.
* Rename FoundryChatClient.HostedAgentName to AgentName and populate it for mode 2
The previous name implied a mode 3 only property tied to the hosted-agent endpoint URL. Today only hosted endpoints surface this name, but conceptually an agent name exists for every server-side agent the client talks to. Renaming to AgentName makes the property general-purpose and ready for future modes where the same chat client may target other server-side agent shapes that are not necessarily 'hosted'.
Mode 2 (server-side agent reference) now mirrors AgentReference.Name into AgentName so callers have a uniform handle regardless of construction mode:
* Mode 1 (pure responses): AgentName is null. There is no agent.
* Mode 2 (AgentReference): AgentName == AgentReference.Name.
* Mode 3 (agent endpoint URL): AgentName is parsed from the URL segment as before.
Converter discriminator update: FoundryPromptAgentConverter previously used 'HostedAgentName is not null' to detect mode 3 and reject it. Now that mode 2 also populates AgentName, the mode 3 guard moves to the end of the resolution chain and uses the unambiguous 'AgentName is set AND no AgentReference exists' test. The user-visible error message and behavior are preserved.
Dead-state cleanup spotted during format verify:
* IDE0052 surfaced that FoundryChatClient._projectOpenAIClient is never read since the prior refactor stopped exposing ProjectOpenAIClient via GetService and rewired CreateConversationSessionAsync to resolve the AIProjectClient through the delegating chain. The field is deleted and its three ctor assignments removed.
* HostedAgentEndpointInner.PerAgentClient only existed to plumb the per-agent ProjectOpenAIClient into that now-deleted field, so the property and its ctor parameter are removed. The local 'perAgentClient' variable inside BuildHostedAgentEndpointInner is still needed to derive the inner IChatClient, but no longer escapes the helper.
Tests:
* Mode1_PureResponses_ReturnsNullForAgentSpecificServices now also asserts AgentName is null.
* New Mode2_AgentReference_PopulatesAgentNameFromAgentReference asserts the mode 2 mirror.
* Mode3_HostedAgentEndpoint_ParsesAgentNameFromUrl renamed assertion target HostedAgentName to AgentName.
Verification: 335/335 net10.0, 273/273 net472 Foundry unit; 229/229 Foundry.Hosting unit; format-verify (WSL2 + Docker mcr.microsoft.com/dotnet/sdk:10.0) clean on Microsoft.Agents.AI.Foundry.
* Adopt canonical mode names: Responses Agent, Prompt Agent, Agent Endpoint
Three FoundryChatClient construction modes now have one canonical noun used everywhere.
* Responses Agent (Mode 1): inline ChatClientAgent, project-level Responses API, no server-side def.
* Prompt Agent (Mode 2): server-side ProjectsAgentDefinition invoked by AgentReference.
* Agent Endpoint (Mode 3): per-agent URL /agents/{name}/endpoint/protocols/openai. Hosted-or-not.
'Hosted' stays the kind of agent (Microsoft.Agents.AI.Foundry.Hosting). Not synonym of Mode 3.
Rings:
1. XML docs + error messages use canonical names. en-GB to en-US: centralises, synthesise.
2. HostedAgentEndpointInner -> AgentEndpointInner, BuildHostedAgentEndpointInner -> BuildAgentEndpointInner.
3. Tests: Mode1_PureResponses_* -> Mode1_ResponsesAgent_*, Mode2_AgentReference_* -> Mode2_PromptAgent_*, Mode3_HostedAgentEndpoint_* -> Mode3_AgentEndpoint_*.
Pure rename. No behavior change. 335/335 net10 + 273/273 net472 unit, format clean.

Rebase onto origin/main reconciliation: aad20c2b3 added public AsAIAgent(this AIProjectClient, Uri agentEndpoint, ...) extension that calls an internal FoundryAgent(AIProjectClient, Uri, ...) ctor. Reintroduced that ctor + a new FoundryChatClient(AIProjectClient, Uri, ProjectOpenAIClientOptions?) overload that reuses the supplied AIProjectClient's pipeline (via GetProjectResponsesClientForAgentEndpoint) instead of stamping a fresh credential.

* Add FoundryAgent helper extensions: UploadFile/DeleteFile/CreateVectorStore/DeleteVectorStore
4 thin forwarders on FoundryAgent that route to the inner FoundryChatClient's helpers via agent.GetService<FoundryChatClient>().X(). Live in existing FoundryAgentExtensions.cs alongside ToPromptAgentAsync.
Throws InvalidOperationException when agent does not expose a FoundryChatClient via GetService (same pattern as ToPromptAgentAsync).
Unit tests: FoundryAgentExtensionsTests covers all 4 forwarders + null-agent ArgumentNullException for each. 8 new tests, 354/354 net10 + 292/292 net472.
Integration tests: parallel FoundryAgentExtensionsTests under Foundry.IntegrationTests mirrors the existing CreateAgent_CreatesAgentWithVectorStoresAsync shape (upload -> create vector store -> FileSearch tool answers question -> cleanup), but routes every helper call through the new FoundryAgent extensions. 4 new IT tests, all verified pass live against the real Foundry project (12-30s each). Skipped by default like the existing vector-store IT.
* Address Sergey's PR review comments
#1 (FoundryAgent.cs:139): drop unused aiProjectClient param from internal FoundryAgent(AIProjectClient, ChatClientAgent) ctor. Was discarded after null-check. Inner FoundryChatClient already surfaces AIProjectClient via GetService. 3 call sites in AIProjectClientExtensions updated.
#2 (FoundryChatClient.cs:376): add pollingTimeout param to CreateVectorStoreAsync. Defaults to 5 min, configurable, Timeout.InfiniteTimeSpan disables. Throws TimeoutException with vector store id and elapsed seconds when bound exceeded. CancellationToken still wins. New unit test PollingTimeout_ThrowsTimeoutExceptionAsync. FoundryAgentExtensions forwarder updated to plumb the new param.

* feat(foundry): add experimental hosted tool factories on FoundryChatClient
Adds eight new `@experimental` static factory methods on `FoundryChatClient`
covering Foundry-hosted tools that previously had no helper:
- get_azure_ai_search_tool
- get_sharepoint_tool
- get_fabric_tool
- get_memory_search_tool
- get_computer_use_tool
- get_browser_automation_tool
- get_bing_custom_search_tool
- get_a2a_tool
All factories are marked with the new `ExperimentalFeature.FOUNDRY_TOOLS` tag
and resolve the underlying `azure-ai-projects` preview classes lazily through
a `_require_sdk_class` helper so older SDK versions still import cleanly and
fail with a clear `ImportError` only on use.
Tests cover each factory's return type and field wiring, the experimental
metadata, and the missing-SDK-class fallback.

* test(foundry): address review comments on tool-factory tests
* Skip preview-tool tests gracefully (`_skip_if_sdk_class_missing`) when
the installed `azure-ai-projects` does not expose the required preview
class, matching the lazy-import guard in production code so the test
suite stays green on older SDK installs.
* Add `filterwarnings("ignore::FutureWarning")` to each new tool-factory
test (and the parametrized metadata test) so they remain stable under
strict warning configurations \u2014 the global dedup in
`_feature_stage._WARNED_FEATURES` makes `pytest.warns` brittle across
ordered runs.
* Use `monkeypatch.setattr(..., None, raising=False)` instead of
`delattr` in the missing-SDK-class test so it works for modules that
implement PEP 562 `__getattr__`.
* Split the long `get_bing_custom_search_tool` return into two lines for
readability.

* fix(foundry): harden tool-factory kwargs against silent override
* Reorder the dict-literal kwargs assembly in get_azure_ai_search_tool,
get_memory_search_tool, and get_bing_custom_search_tool so explicit
parameters always take precedence over **kwargs (matching the safe
pattern already used in get_a2a_tool). This prevents a caller
passing `project_connection_id`, `index_name`, `memory_store_name`,
`scope`, or `instance_name` through `**kwargs` from silently
overriding the explicit security-sensitive arguments.
* Update the README experimental note to reflect once-per-feature-id
dedup semantics of `_feature_stage._WARNED_FEATURES` rather than
claiming a per-factory "first use" warning.

* feat(foundry): split FOUNDRY_TOOLS / FOUNDRY_PREVIEW_TOOLS, add bing-grounding
- Add ExperimentalFeature.FOUNDRY_PREVIEW_TOOLS to distinguish wrappers around
preview Foundry SDK tool classes (Sharepoint/Fabric/Memory/ComputerUse/
BrowserAutomation/BingCustomSearch/A2A) from FOUNDRY_TOOLS, which is for
GA-SDK wrappers that are simply new in agent-framework-foundry
(AzureAISearch, BingGrounding).
- Add get_bing_grounding_tool factory and a 'Choosing a web grounding tool'
comparison block on get_web_search_tool / get_bing_grounding_tool /
get_bing_custom_search_tool docstrings.
- Drop the _require_sdk_class lazy resolver: every guarded class is available
at azure-ai-projects>=2.1.0 (the package floor), so import them eagerly.
Concrete return types replace 'Any'.
- README: split the experimental factories into two tables, one per feature
flag, with a note explaining the distinction.
- Tests: split into FOUNDRY_TOOLS / FOUNDRY_PREVIEW_TOOLS factory cases;
drop the obsolete missing-SDK-class ImportError test.

* Show more authentication methods in Foundry Toolbox MCP
* Remove hardcoded toolbox version num
* Add Foundry MCP OAuth consent handling
* Use message instead of the dedicated item type
* Go back to using OAuthConsentRequestOutputItem
* WIP: sample testing
* Update error code
* Address review on Foundry Toolbox MCP samples
Reviewed feedback addressed:
- Drop the branch-pinned `git+https://...@feature/...` entries from
`04_foundry_toolbox/requirements.txt`; restore the simple comment + `mcp`
runtime dep. The git pins were only useful while iterating on the PR and
shouldn't ship. (eavanvalkenburg)
- Fix the `/toolsets/` typo in both `04_foundry_toolbox/README.md` and
`06_files/README.md`. Verified empirically against the
research_toolbox in the test workspace: the toolbox MCP gateway lives at
`/toolboxes/{name}/mcp?api-version=v1` and requires the
`Foundry-Features: Toolboxes=V1Preview` header. `/toolsets/{name}/mcp`
returns 403 with `preview_feature_required: Toolsets=V1Preview` (a
different opt-in feature).
- Wrap `httpx.AsyncClient(...)` in `async with ... as http_client:` in both
samples so the connection pool is cleaned up. (Copilot reviewer)
- Make the `TOOLBOX_NAME` env var consistent in both samples. Previously the
tool name silently fell back to `"toolbox"` when `TOOLBOX_NAME` was unset,
but `resolve_toolbox_endpoint()` still required `TOOLBOX_NAME` and would
raise `KeyError`. The samples now resolve the endpoint once and derive the
tool name from the resolved URL when `TOOLBOX_NAME` isn't set, so the
local tool name always matches the upstream toolbox identity regardless
of which env var the user set. (Copilot reviewer)
- Rename `_responses.is_consent_error` to `consent_url_from_error`: the
helper returns `str | None` (the consent URL), not a bool, so the new
name matches behavior. Update the test class accordingly. (eavanvalkenburg)
- Tighten `_handle_inner_agent`'s lazy-entry catch from `Exception` to
`AgentFrameworkException`, the type the MCP layer actually wraps consent
errors in via `MCPStreamableHTTPTool.__aenter__` →
`ToolExecutionException(inner_exception=mcp_error)`. Network failures,
cancellations, and other non-framework exceptions now propagate normally
instead of being briefly caught and re-raised. The test helper
`_make_consent_error` is updated to use `ToolExecutionException` so it
matches the real-world wrapping. (eavanvalkenburg)
- Clarify the `github_pat` description in `agent.manifest.yaml` to note
it's only needed when the PAT-based connection (`github-mcp-pat-conn`)
is chosen; users selecting the OAuth2 connection (`github-mcp-oauth-conn`)
can leave it empty. (Copilot reviewer)
Validation: ran both samples end-to-end against a real Foundry toolbox
(`research_toolbox`) -- the samples connect successfully and the agent
lists the toolbox's MCP tools (`api_specs___fetch_azure_rest_api_docs`,
etc.). `uv run poe test -P foundry_hosting` passes (119 tests), pyright +
mypy clean.

* Enable instrumentation by default
* Update samples
* Optimization when span is not recording
* Address Copilot comments
* Revert uv.lock
* Add warning
* Formatting
* Fix mypy
* Add disable_instrumentation() with sticky user-intent semantics
Add a public disable_instrumentation() entry point so users can explicitly opt
out of Agent Framework telemetry, with a sticky-disable flag that makes the
user's intent "leading" — no framework code path (foundry's
configure_azure_monitor, configure_otel_providers, enable_instrumentation,
enable_sensitive_telemetry, or direct OBSERVABILITY_SETTINGS.enable_*
writes) can re-enable instrumentation until the user explicitly clears the
disable with enable_instrumentation(force=True) /
enable_sensitive_telemetry(force=True).
Also addresses the two remaining unresolved review threads on the PR:
1. test_observability_settings_defaults_instrumentation_true pins the new
"ENABLE_INSTRUMENTATION defaults to True when env unset" behavior.
2. test_enable_instrumentation_reads_env_sensitive_data restores coverage
for the post-import load_dotenv() fallback path.
Implementation:
- ObservabilitySettings.enable_instrumentation / enable_sensitive_data become
properties backed by _enable_*. While _user_disabled is True, the getters
return False and the setters drop True writes (defense in depth so third-
party writes can't subvert the disable).
- Public is_user_disabled read-only property lets integrations (e.g. foundry's
configure_azure_monitor) cheaply check the disable state without poking at
privates.
- enable_instrumentation() and enable_sensitive_telemetry() short-circuit with
an info log when disabled; gain a force=True kwarg that clears the disable.
- configure_otel_providers() still creates providers / exporters / views so a
later force-enable can use them, but logs an info message when called while
disabled.
- Foundry's FoundryChatClient.configure_azure_monitor and
FoundryAgent.configure_azure_monitor early-return when the user has
disabled, so Azure Monitor's global providers aren't installed unnecessarily.
Tests: 11 new tests covering default-on, env re-read at call time, sticky
behavior against each re-enable surface (enable_instrumentation,
enable_sensitive_telemetry, configure_otel_providers, direct attribute
writes), force=True override, re-arming the disable, and the __all__ export.

* docs: document disable_instrumentation() and force=True paths
Add a "Disabling instrumentation" section to the observability sample README
that walks through:
- The distinction between the ENABLE_INSTRUMENTATION env var (initial,
non-sticky) and disable_instrumentation() (process-wide, sticky).
- Why the sticky semantics matter: framework integrations like
FoundryChatClient.configure_azure_monitor() can call
enable_instrumentation() as part of their setup, and the user's opt-out
needs to win.
- All five surfaces guarded by the sticky disable (property reads, public
enable functions, configure_otel_providers, direct attribute writes,
is_user_disabled-aware integrations).
- The force=True escape hatch on both enable_instrumentation() and
enable_sensitive_telemetry().
- How third-party integrations should consult OBSERVABILITY_SETTINGS.is_user_disabled.
- The limits of the disable (does not tear down existing providers /
in-flight spans / third-party instrumentation, does not persist across
processes).
Cross-links the new section from the ENABLE_INSTRUMENTATION row in the env
vars table.

* docs: soften disable_instrumentation() overclaim about telemetry guarantees
Replace 'no telemetry will be emitted no matter what' (which is too strong,
since callers can still pass force=True or mutate private attributes) with
language framing the disable as a user-intent contract that library and
framework code is expected to honor: the framework actively short-circuits
the public enable paths, force=True and private-attribute writes are
acknowledged as out-of-contract escape hatches that integrations should
not use on the user's behalf.

* docs: correct observability Dependencies section
- opentelemetry-sdk is no longer a hard dependency; it is lazily imported by
create_resource(), create_metric_views(), and configure_otel_providers()
with a clear ImportError when missing. Day-to-day instrumentation works
with opentelemetry-api alone provided some other component configures the
global OpenTelemetry providers (Azure Monitor, an APM agent, application
bootstrap, etc.).
- opentelemetry-semantic-conventions-ai is no longer used anywhere in the
source; remove it from the listed dependencies.

* docs: replace stale observability migration guide with current PR's only relevant migration
The old guide documented the move away from setup_observability(otlp_endpoint=...)
which was an earlier-release API change unrelated to this PR and stale enough that
it's more confusing than helpful at this point. Replace it with a short note on the
single migration this PR introduces: callers of
enable_instrumentation(enable_sensitive_data=True) should switch to
enable_sensitive_telemetry(). Cross-link to the Disabling instrumentation section
for the rare 'force on without enabling sensitive data' use case where
enable_instrumentation() still applies.

* .NET: Add A2AAgentOptions and align A2AAgent constructors with ChatClientAgent pattern
Adds a new A2AAgentOptions class (Id, Name, Description, Clone) and an options-based constructor on A2AAgent, mirroring ChatClientAgent/ChatClientAgentOptions. The existing parameter-based constructor is preserved for backward compatibility and now delegates to the options-based one.
Extension methods are extended with options-based overloads:
- A2AClientExtensions.AsAIAgent(IA2AClient, A2AAgentOptions, ...)
- A2AAgentCardExtensions.AsAIAgent(AgentCard, A2AAgentOptions, ...)
- A2ACardResolverExtensions.GetAIAgentAsync(A2ACardResolver, A2AAgentOptions, ...)
For card-based creation, user-supplied options override values from the agent card; Name and Description fall back to card values when not set.
Options are cloned when stored on the agent to prevent post-construction mutation, matching the ChatClientAgent pattern.
Resolves#5870.

code change.
Public API (agent_framework_monty):
- MontyCodeActProvider — ContextProvider that injects a run-scoped
execute_code tool plus dynamic CodeAct instructions.
- MontyExecuteCodeTool — standalone FunctionTool for mixed-tool agents
or manual static wiring.
- FileMount / FileMountInput / MountMode — public types mirroring the
Hyperlight names, with Monty's mode (read-only/read-write/overlay)
and write_bytes_limit on FileMount.
Constructor kwargs (both classes) mirror Hyperlight where possible:
tools, approval_mode, workspace_root, file_mounts; plus a Monty-only
resource_limits forwarding ResourceLimits to Monty.start().
Filesystem flow:
- workspace_root auto-mounts at /input (read-write), matching Hyperlight.
- file_mounts accepts string shorthand, (host, mount) tuple, or
FileMount with mode + write cap.
- Files written under read-write mounts are scanned post-execution and
returned as Content.from_data items (mirrors Hyperlight /output).
- overlay mounts buffer writes in-memory; read-only mounts reject writes.
Internals:
- _monty_bridge.InlineCodeBridge ports the inline (non-durable) bridge
from anthonychu/maf-codeact-monty-python; handles FunctionSnapshot /
FutureSnapshot pause/resume, dispatches direct typed calls + the
call_tool fallback, forwards mount/limits to Monty.start(...).
- generate_type_stubs emits per-tool stubs so Monty's `ty` type-checker
rejects bad calls before any host tool runs.
Alpha-policy compliance (per python-package-management skill):
- Added agent-framework-monty = { workspace = true } to root
pyproject.toml.
- Added row to python/PACKAGE_STATUS.md.
- Added monty entry under Experimental in python/AGENTS.md.
- NOT added to core[all]; NO agent_framework.monty lazy shim (deferred
to beta promotion).
Samples (three sets, import from agent_framework_monty directly):
- samples/02-agents/context_providers/code_act/monty_code_act.py
(provider pattern) + updated local README.
- samples/02-agents/tools/monty_code_interpreter/ (standalone +
manual-wiring + README).
- samples/04-hosting/foundry-hosted-agents/responses/11_monty_codeact/
(full hosted-agent layout with uv-based pyproject.toml + Dockerfile,
Azure Monitor wiring via APPLICATIONINSIGHTS_CONNECTION_STRING +
enable_instrumentation, ENABLE_INSTRUMENTATION and
ENABLE_SENSITIVE_DATA env vars). The alpha wheel is vendored into
./wheels/ (gitignored) via vendor-wheel.sh; new row added to the
parent Responses-API README.
Tests:
- 28 hermetic unit tests (stubbed pydantic_monty).
- 18 integration tests marked @pytest.mark.integration, auto-skipped
when pydantic_monty is unimportable; exercise the real Monty
runtime: print round-trip, last-expression value, direct typed
tool dispatch, call_tool fallback, async tool, asyncio.gather
parallelism, ty type-check rejection, OS blocked by default,
workspace_root read+write capture, read-only / overlay mount
semantics, resource_limits.max_duration_secs abort, approval
gating end-to-end, full Agent run with a scripted chat client.

* Python: fix: monty FileMount test compares against the normalized POSIX path
The shorthand string mount goes through _normalize_mount_path, which
rewrites Windows drive letters like 'C:\\Users\\...' into
'/C:/Users/...' (POSIX-style). The Windows CI runners surfaced this
because tmp_path resolves to a backslashed Windows path; the test was
comparing against the raw str(host_a) instead of the normalized form.
Compare against _normalize_mount_path(str(host_a)) so the assertion is
platform-independent.

* Python: fix: address PR #5915 review feedback
- _execute_code_tool docstring: clarify that the Monty backend supports
scoped filesystem access via workspace_root / file_mounts (blocked by
default).
- _to_monty_mount: import pydantic_monty lazily through load_monty so
missing-dependency errors surface as the same actionable RuntimeError
the rest of the package raises (not a bare ImportError at module load).
Renamed _load_monty -> load_monty for the same reason.
- _python_type_repr: emit None for type(None) instead of Any, and
normalize both typing.Union[...] and PEP-604 X | Y to PEP-604 syntax
so Optional[X] / Union[..., None] / -> None signatures round-trip
correctly through ty validation. Added a regression test.
- _PrintCollector: track a running character count instead of
recomputing sum(len(c) for c in self.chunks) per callback. Eliminates
the O(n^2) cost on print-heavy code.
- Instructions: mention that the value of the final expression is also
returned alongside captured stdout (matches actual behavior).
- 11_monty_codeact Dockerfile: pin ghcr.io/astral-sh/uv to 0.11.6
instead of :latest for reproducible builds.
- 11_monty_codeact README: replace the bare "see parent README" pointer
with sample-specific steps (./vendor-wheel.sh + uv sync + uv run),
since the sample uses pyproject.toml + a vendored wheel rather than
requirements.txt.

* Python: sample: 11_monty_codeact installs agent-framework-monty from PyPI
Drop the vendored-wheel scaffolding now that agent-framework-monty is on
PyPI as an alpha (1.0.0a*) release:
- pyproject.toml: remove [tool.uv.sources] override; keep [tool.uv]
prerelease = "allow" so uv pulls the alpha automatically.
- Dockerfile: drop the COPY wheels/ step.
- README: drop the ./vendor-wheel.sh setup step and the
not-yet-on-PyPI warning.
- Delete vendor-wheel.sh and the gitignored wheels/ directory.

* Python: fix(monty): harden post-execution file capture against symlink escape
Same class of issue as the MSRC-reported Hyperlight finding: the
post-execution capture walked workspace_root with Path.rglob() +
is_file() + read_bytes() - all of which follow symlinks. An attacker
who controls the workspace (cloned repo, extracted archive, shared
workspace) could pre-place `workspace/leak.txt -> /etc/passwd` or
`workspace/outside_dir -> /etc/` and have host files surface as
captured Content items.
Monty's mount layer already rejects symlink reads from inside the
sandbox across all three modes (verified empirically), so the runtime
path was safe. This commit closes the post-execution scan path.
Changes:
- New `_iter_real_files(root)` walker that uses iterdir() +
is_symlink() to skip symlinks at every directory level and yields
only real files. Replaces the previous `host_root.rglob("*")` calls
in both `_snapshot_writable_mounts` and `_capture_written_files`.
- Use `Path.lstat()` instead of `Path.stat()` so size/mtime can never
be taken from a symlink target.
- Three new integration tests reproducing the MSRC attack shape
against the workspace_root flow: symlink-to-file outside workspace,
symlink-to-directory outside workspace, and a guard ensuring
legitimate sandbox writes are still captured when symlinks are
present.
Per user request, hyperlight is untouched in this commit (separate fix).

* Python: fix(monty): skip symlink regression tests when unsupported
Apply the same Windows-CI safety guard as the hyperlight fix in PR #5919:
the three symlink integration tests create symlinks via Path.symlink_to(),
which fails with OSError / NotImplementedError on unprivileged Windows
runners. Add a local _symlinks_supported helper (mirroring the one in
packages/core/tests/core/test_skills.py) and pytest.skip when symlinks
aren't available, so the tests no longer fail for environment reasons.

* Python: fix(monty): address PR #5915 follow-up review feedback
- _invoke_tool: drop the inspect.iscoroutinefunction(...) branch and
always `await self.tool_map[name](**kwargs)`. Every entry in
tool_map is `partial(FunctionTool.invoke, skip_parsing=True)` and
FunctionTool.invoke is `async def`, so the branching was dead code -
and on Python versions affected by cpython#98590,
iscoroutinefunction(partial(bound_async_method, ...)) returns False,
causing the bridge to take the asyncio.to_thread path, return an
unawaited coroutine, and surface it as a JSON-serialization failure
for every tool call. Added a regression test
test_invoke_tool_awaits_partial_wrapped_async_method.
- generate_type_stubs: skip tools whose name is not a valid Python
identifier or is a Python keyword. FunctionTool.name has no upstream
validation, so a name like "weird-name" produced a syntax error in
the stubs and a name like "broken\n pass\nasync def injected"
would inject arbitrary stub source. Non-identifier names stay
reachable via `call_tool("weird-name", ...)` at runtime; they just
don't get type-checked stubs. Added regression test
test_generate_type_stubs_skips_non_identifier_tool_names.

* Bump Python package versions to 1.5.0 for a release
* Promote orchestrations to 1.0.0rc1
* ci(python-setup): merge dynamic exclude into existing workspace exclude
The python-setup action injected exclude = [...] verbatim into
[tool.uv.workspace], producing a duplicate 'exclude' key when the
section already had a static exclude. Scope the rewrite to the
[tool.uv.workspace] section and append the package to the existing
array when present; idempotent if the package is already excluded.
* Address Copilot review feedback: raise inter-package floors to 1.5.0
- foundry, foundry-local: agent-framework-openai >=1.4.0 -> >=1.5.0
- azure-contentunderstanding: agent-framework-foundry >=1.4.0 -> >=1.5.0
- azurefunctions: pin agent-framework-durabletask to >=1.0.0b260519,<2
Keeps lockstep cohort consistent and avoids mixed 1.4.x / 1.5.0 installs.
* Re-include azurefunctions and durabletask in the uv workspace
The pinned durabletask>=1.4.0 floor is enough to make resolution succeed;
the workspace exclude was over-correction and broke CI samples and pyright
type-checking (re-exports in agent_framework/azure/__init__.pyi plus
samples/04-hosting/{azure_functions,durabletask}/ could not resolve their
imports). Dropping them from agent-framework-core[all] still stands so the
metapackage does not pull them.
* Restore azurefunctions and durabletask in agent-framework-core[all]
The durabletask floor pin keeps users on the safe 1.4.0, so they are once
again included in the metapackage. Update CHANGELOG to reflect the pin
rather than an [all] removal.
* Raise uvicorn ceiling in ag-ui and devui to allow 0.42+
The root override-dependencies pins uvicorn[standard]>=0.34.0 (no upper)
and the workspace lock resolves to 0.47.0. The package ceiling <0.42.0
meant the workspace was no longer testing the declared supported range.
Bump to <1 so the lock fits within the declared bounds.
Also picked up by validate-dependency-bounds: refresh stale orchestrations
RC pin in devui dev deps.
The shared composite action ran `uv sync --all-packages --all-extras
--dev -U` on every job, which upgrades every dependency to the latest
compatible version instead of using the pinned versions in `uv.lock`.
That is currently producing a hard resolver failure on every CI job:
No solution found when resolving dependencies for split
(markers: python_full_version >= '3.11' and sys_platform == 'darwin')
Because there are no versions of durabletask and
agent-framework-durabletask depends on durabletask>=1.3.0,<2,
we can conclude that agent-framework-durabletask's requirements
are unsatisfiable.
Dropping `-U` makes the install use the workspace lockfile, which is
what is reproducible locally and what we publish releases against.
Upgrades should be opt-in (via a scheduled job or a separate workflow)
rather than implicit on every CI run.

* Add sample that shows code execution and skills together
* Use nuget for python module path
* Update readme.
* Fix formatting.
* Reduce flashing in rendering.
* Improve screen clearing for Powershell
* Add a couple of small UX fixes
The second self._cache.pop(key, None) call is a guaranteed no-op: the first pop has already removed the key (or returned None), and there is no await between the two statements that could allow another coroutine to re-add it. Removing the dead line clarifies intent without changing behavior.
* Python: fix(hyperlight): skip symlinks when staging files into the sandbox
The helpers that populate the sandbox input tree (``_copy_path`` and the
``_path_tree_signature`` walker used for cache invalidation) relied on
``Path.is_file()``, ``Path.is_dir()`` and ``shutil.copy2`` - all of which
follow symlinks by default. When the source tree contains symlinks, that
let entries from outside the configured input source surface inside the
sandbox.
Harden both code paths to never follow symlinks:
- ``_copy_path`` now bails out via ``Path.is_symlink()`` before any
``is_dir()`` / ``is_file()`` check, skips non-regular files, and uses
``shutil.copy2(..., follow_symlinks=False)`` as defense in depth.
- New ``_iter_real_entries`` walker replaces the previous ``Path.rglob``
call inside ``_path_tree_signature`` (rglob follows directory symlinks).
- ``_path_tree_signature`` switches to ``Path.lstat()`` so size/mtime are
never read through a symlink target.
Added regression tests covering:
- A pre-placed file symlink in ``workspace_root`` (top level).
- A pre-placed directory symlink in ``workspace_root``.
- A nested file symlink inside a real subdirectory.
- ``_path_tree_signature`` ignoring symlinks so the cache key reflects only
what is actually staged.

* Python: fix(hyperlight): address PR #5919 review feedback
- _iter_real_entries now yields directories and regular files only,
skipping non-regular entries (sockets/FIFOs/devices). Keeps the
cache-key signature consistent with what _copy_path actually stages.
- The four new symlink regression tests skip when the platform does not
support symlink creation (e.g. unprivileged Windows runners), via a
local _symlinks_supported helper modelled on the one in
packages/core/tests/core/test_skills.py. Prevents OSError /
NotImplementedError from failing CI jobs that have nothing to do with
the change under test.

* Python: fix(hyperlight): address PR #5919 follow-up review feedback
- _copy_path docstring: narrow the scope to "symlink entries present in
the source tree at rest" and explicitly call out that the copy is NOT
atomic with respect to concurrent mutation of the source tree.
Callers who need that stronger guarantee should snapshot their
workspace before passing it in. Avoids overpromising on a TOCTOU
window that pathlib cannot express; closing it properly would need
fd-based traversal (O_NOFOLLOW | O_DIRECTORY + os.scandir(fd)) with
a separate Windows story, which is out of scope for this targeted
fix.
- _path_tree_signature: drop the `if path.is_symlink(): return ()`
short-circuit. Resolve a symlink root to its real target before
walking instead. The public construction flow already resolves
workspace_root / file_mounts[].host_path up front so this never
affected user-facing code, but the short-circuit was misleading and
would have produced an empty, stable signature for any direct
caller that builds a _RunConfig without going through the public
constructor. Defense in depth: even if a future call site forgets
to resolve the root, the cache key still reflects real contents.
- Added regression test
test_path_tree_signature_walks_through_symlinked_root: a symlinked
workspace root must produce a non-empty signature, AND the signature
must change when the real target's contents change so the cache key
actually invalidates.

* Record actual served model as response model for Azure OpenAI
* Formatting
* Fix tests
* Fix pipeline error
* Comments
* Address review: surface served model via ChatResponse.model
Apply blocking review feedback from PR #5910:
- Use ChatResponse.model / ChatResponseUpdate.model as the source of truth
for the Azure x-ms-served-model header value, instead of stashing it in
additional_properties and overriding it again in observability.
Observability already reads response.model; the chat client now overwrites
it post-parse when the served-model header is present. Empirically the
Azure Responses API returns the deployment alias in body.model and the
actual snapshot (e.g. gpt-5-nano-2025-08-07) in this header.
- Move the AZURE_OPENAI_SERVED_MODEL_HEADER constant out of observability.py
and into RawOpenAIChatClient (as the SERVED_MODEL_HEADER ClassVar). The
header is Azure-OpenAI-Responses-API-specific so observability does not
need to know about it.
- Revert the streaming text_format path to client.responses.stream(...) and
drop the _pydantic_model_to_text_format_param helper. That helper imported
from openai.lib._parsing._responses (a private SDK path) and the swap to
responses.create(stream=True) dropped client-side output_parsed for
structured-output streaming. The streaming-with-text_format path is the
only one that does not surface the served-model header - documented inline.
- Wrap the raw streaming responses in async with so the underlying socket
closes deterministically (continuation_token retrieve + create paths).
- Fix the empty-string / whitespace-only header at the source by stripping
in _extract_served_model and returning None when nothing remains.
- Revert unrelated formatting-only churn in _skills.py and test_mcp.py.
- Update unit tests to assert against chat_response.model / update.model
and add an aggregated streaming assertion plus a pin that the
streaming-with-text_format path does not get the header.
Verified end-to-end against Azure OpenAI Responses API: deployment alias
gpt-5-nano now reports gpt-5-nano-2025-08-07 as ChatResponse.model in both
the non-streaming and streaming paths.

* Inline the served-model header override at its two call sites
The `_apply_served_model_header` helper was a 1-line wrapper around
`_extract_served_model`. Inlining the `if served_model is not None: ...`
matches the pattern already used in the streaming paths and folds the
explanatory docstring onto `_extract_served_model` (which is now the
single place that knows about the header).

* Improve the handling of intermediate outputs for workflows and orchestrations
* Address PR review feedback on intermediate output forwarding
- Switch workflow.as_agent() forwarding to an explicit allowlist of {output,
intermediate, data, request_info} so orchestration-internal events
(group_chat, handoff_sent, magentic_orchestrator) stay inside the workflow
instead of leaking into agent responses via str(data) coercion.
- Stop raising on intermediate AgentResponseUpdate in non-streaming run();
surface the partial as a Message with text_reasoning content. The defensive
raise still applies to terminal output events, where Update payloads would
corrupt message ordering.
- Extend the DevUI workflow-event mapper so intermediate yields wrapping
plain strings, Messages, and list[Message] render as visible output items
instead of generic completed-trace events.
- Add orchestration coverage for GroupChat, Handoff, and Magentic builders
(default vs intermediate_outputs=True; structural where end-to-end is heavy).
* Lift output-designation policy into a value type
Replace the ``Workflow._output_executors`` list and the
``RunnerContext.should_label_as_intermediate`` Protocol method with a single
immutable ``OutputDesignation`` value type owned by ``Workflow``. Thread the
designation as a parameter through the existing call chain (Runner ->
EdgeRunner -> Executor -> WorkflowContext) so ``yield_output`` consults the
threaded snapshot directly rather than calling back into the runner context.
Removes the ``InProcRunnerContext._workflow`` back-reference and the
``WorkflowBuilder.build()`` assignment that wired it up. Adds the public
predicate ``Workflow.is_terminal_executor(executor_id)`` for external
observers; ``OutputDesignation`` itself stays package-internal.
Key decisions
- ``OutputDesignation.designated`` is ``frozenset[str] | None`` -- ``None``
preserves legacy "every yield is type='output'" behavior, any frozenset
(including empty) opts into strict mode. The ``DeprecationWarning`` for
legacy mode at build time is unchanged.
- ``output_designation`` is an optional parameter on ``Runner``,
``EdgeRunner.send_message``, ``EdgeRunner._execute_on_target``,
``Executor.execute``, ``Executor._create_context_for_handler``, and
``WorkflowContext.__init__``. Each defaults to legacy ``OutputDesignation()``
so direct callers (Azure Functions ``CapturingRunnerContext``,
``test_runner`` recording fixtures) keep working without ceremony.
- The workflow-level filter in ``_run_core`` reads ``self._output_designation``
live, preserving today's semantics where mutating the designation after
build still affects subsequent runs (used by two existing tests).
- ``Workflow.to_dict()`` continues to emit ``"output_executors":
list[str] | None`` (sorted from the frozenset). Checkpoint format unchanged.
Files changed
- _workflow.py: add ``OutputDesignation`` dataclass; replace
``_output_executors`` with ``_output_designation``; add
``is_terminal_executor``; delete ``_should_yield_output_event``.
- _runner_context.py: drop ``should_label_as_intermediate`` Protocol method
and ``InProcRunnerContext`` impl; drop ``_workflow`` back-reference.
- _workflow_builder.py: remove ``context._workflow = workflow`` assignment.
- _runner.py, _edge_runner.py, _executor.py, _workflow_context.py: thread
``output_designation`` parameter through the call chain.
- tests/workflow/test_output_designation.py (new): three-state coverage of
the value type plus the public predicate delegation.
- tests/workflow/test_workflow_builder.py, test_validation.py,
test_workflow.py, test_runner.py and
orchestrations/tests/test_orchestration_intermediate_vs_terminal.py:
switch probes from ``_output_executors`` set checks to
``get_output_executors`` / ``is_terminal_executor``; update two
post-build mutation tests to set ``_output_designation`` instead.
Verification
- core/tests/workflow/, orchestrations/tests/, azurefunctions/tests/:
1119 passed, 42 skipped, 2 xfailed.
- ``uv run poe lint``: clean.
- ``uv run poe typing``: only the pre-existing
``_AGENT_FORWARDED_EVENT_TYPES`` pyright warning from 394bcd607 remains.
Notes for next iteration
- The builder's own ``_output_executors`` attribute (``list[Executor |
SupportsAgentRun]``) is intentionally untouched; the issue scoped the
rename to the workflow attribute.
- Adjacent review candidates (twin ``WorkflowAgent`` translators,
``_AGENT_FORWARDED_EVENT_TYPES`` kind classifier,
``_event_origin_context`` ContextVar removal, ``WorkflowEvent`` ADT
split, legacy-mode removal) remain out of scope.
* Add explicit workflow output designation
Key decisions
- Extend the internal OutputDesignation value type from terminal-only membership to output/intermediate/hidden classification. Legacy mode remains outputs=None, so workflows built without output_executors or intermediate_executors still label every yield_output as type='output'.
- WorkflowBuilder now accepts intermediate_executors. Providing either designation enters explicit mode; output executors emit output, intermediate executors emit intermediate, and unlisted yield_output payloads are hidden from caller-facing events while remaining in executor_completed data.
- Empty explicit designation, duplicate entries, overlaps, unknown executors, and designated executors without workflow output annotations fail build validation. Existing orchestration builders pass intermediate-capable participants through intermediate_executors to preserve current intermediate_outputs behavior until participant-oriented designation lands.

* Tighten workflow-as-agent output mapping
Key decisions
- Treat AgentResponseUpdate as a streaming-only payload across the workflow.as_agent() adapter, so non-streaming agent runs now reject both terminal output and intermediate workflow events carrying updates.
- Keep streaming classification behavior explicit: terminal update payloads remain normal text content, while intermediate update payloads are rewritten to text_reasoning content.
- Add explicit-mode coverage proving hidden yield_output emissions do not appear in non-streaming AgentResponse messages or streaming AgentResponseUpdate chunks.

- Replace orchestration intermediate_outputs with participant-oriented output_participants and intermediate_participants across Sequential, Concurrent, GroupChat, Magentic, and Handoff builders.
- Keep synthetic final executors terminal by default for Concurrent, GroupChat, and Magentic; keep Sequential's final participant terminal by default; keep Handoff participants terminal by default.
- Centralize participant designation validation for empty explicit designation, duplicates, overlaps, and unknown participants, then map validated participants to workflow output/intermediate executors.

* Migrate samples to explicit output designation
Key decisions
- Replace sample usage of the removed orchestration intermediate_outputs boolean with participant-oriented intermediate_participants designation.
- Update raw workflow guidance to show output_executors together with intermediate_executors, and document that unlisted yields are hidden in explicit designation mode.
- Keep orchestration final outputs terminal while streaming designated participant responses as intermediate progress, including workflow.as_agent() samples where intermediates map to text_reasoning content.
- Refresh workflow and orchestration README guidance plus the changelog reference so public docs no longer point users at intermediate_outputs.

* Fix mypy
* Clarify orchestration participant output config
* Rename participant output kwargs for clarity
output_participants -> final_output_from, intermediate_participants ->
intermediate_output_from. The old names read like categories of
participant; the new names make it clear the kwarg designates which
participants' outputs surface as final vs. intermediate events.
* Rename core workflow output kwargs with deprecation shim
Adds final_output_from / intermediate_output_from as canonical kwargs on
Workflow and WorkflowBuilder. Old output_executors / intermediate_executors
kwargs continue to work but emit DeprecationWarning via a shared coalesce
helper that also rejects supplying both. Wire-format keys in to_dict()
stay as output_executors / intermediate_executors so checkpoint
compatibility is preserved.
Internal call sites in orchestrations and samples updated to the new
names so users following sample code learn the canonical vocabulary;
legacy callers still work with a one-shot warning.
* Suppress pyright reportPrivateUsage on cross-module sentinel import
* Update docstrings
* Propagate sub-workflow intermediate outputs, fix handoff/sequential intermediate-only designation, and shore up tests, sample, and docstrings around the intermediate output contract.
* Add canonical workflow output_from selection
Key decisions:\n- Make output_from the canonical workflow-output allow-list and keep output_executors/final_output_from as deprecated compatibility aliases.\n- Treat empty output_from/intermediate_output_from lists as explicit selections and keep validation responsible for empty, duplicate, overlap, and unknown selections.\n- Remove the branch-only public intermediate_executors WorkflowBuilder kwarg while preserving legacy wire keys in to_dict().\n\nFiles changed:\n- packages/core/agent_framework/_workflows/_workflow.py\n- packages/core/agent_framework/_workflows/_workflow_builder.py\n- packages/core/agent_framework/_workflows/_workflow_context.py\n- packages/core/agent_framework/_workflows/_agent.py\n- packages/core/agent_framework/_workflows/_agent_executor.py\n- packages/core/tests/workflow/* output-selection coverage updates\n- packages/core/AGENTS.md\n- issues/done/001-canonical-list-based-output-selection.md\n\nBlockers/notes:\n- Orchestration builders still pass final_output_from internally; follow-up issue 004 should migrate them to output_from.\n- Legacy omitted-selection behavior and explicit all/all_other literals are left for issues 002 and 003.
* Add explicit all workflow output selection
Key decisions:
- Treat output_from='all' as an explicit workflow-output selection sentinel and expand it at build time to executors with declared workflow output types.
- Keep omitted output selections in legacy all-output mode with a deprecation warning that names output_from and intermediate_output_from and points to output_from='all'.
- Reject intermediate_output_from='all' at construction because the all-output literal is output-only for this issue.

Blockers/notes:
- all_other intermediate-output selection remains for issue 003.
- Workflow-as-agent/orchestration parity remains for issue 004.
* Add all-other intermediate output selection
Key decisions:
- Treat intermediate_output_from='all_other' as an explicit intermediate-output selection sentinel and expand it at build time after the workflow graph is complete.
- Expand all_other to output-capable executors not selected by output_from; omitted or empty output_from selects no workflow outputs, while output_from='all' leaves an empty intermediate selection.
- Keep output_from='all_other' invalid so all_other remains intermediate-output-only and runtime classification still receives concrete executor-id sets.

Blockers/notes:

- Full documentation updates remain for issue 005.
* Add orchestration output selection parity
Key decisions:
- Expose output_from on sequential, concurrent, group chat, handoff, and magentic builders while keeping final_output_from as a deprecated compatibility alias.
- Resolve orchestration participant selections through the same explicit rules as workflows: output_from='all', intermediate_output_from='all_other', hidden unselected participant payloads, and overlap/duplicate/unknown/invalid-literal validation.
- Continue preserving documented orchestration defaults by always designating each pattern's terminal internal executor where applicable.

- Existing tests that intentionally use final_output_from now emit the new deprecation warning.
* Document workflow output selection contract
Key decisions:
- Use Workflow Output and Intermediate Output as the developer-facing terms for selected caller-facing emissions.
- Document output_from and intermediate_output_from as the canonical API, with output_from as an allow-list and unselected payloads hidden unless explicitly selected as intermediate.
- Add scenario and invalid-selection tables for workflow and orchestration docs, including legacy omission warnings, output_from='all', intermediate_output_from='all_other', list selections, invalid literals, overlap, duplicates, unknown selections, and empty explicit selections.
- Migrate samples away from final_output_from and output_executors except where compatibility aliases are explicitly documented.

* Latest updates
* Typing fixes
* Cleanup
* .NET: Bump Azure.AI.Projects to 2.1.0-beta.2 and add agent-endpoint AsAIAgent path
Bumps Azure.AI.Projects to 2.1.0-beta.2 with the matching transitive pins (Azure.Core 1.55.0, System.ClientModel 1.11.0).
Foundry agent endpoint plumbing:
* FoundryAgent now routes the agent-endpoint constructor through the new GetProjectResponsesClientForAgentEndpoint helper.
* Adds an internal FoundryAgent ctor that takes an existing AIProjectClient plus a parsed agent endpoint so the public extension does not need to construct a second project client.
* Adds public AIProjectClient.AsAIAgent(Uri agentEndpoint, ...) extension. This is the path consumer samples are expected to use for hosted agents because version selection happens server-side.
* Trims the dangling "If you want to construct a FoundryAgent against a project endpoint..." sentence from ParseAgentEndpoint.
Unit tests:
* Four new tests in AzureAIProjectChatClientExtensionsTests cover the AIProjectClient.AsAIAgent(Uri agentEndpoint, ...) overload. 263/263 pass.
Consumer samples (Using-Samples):
* SimpleAgent and SessionFilesClient now read AZURE_AI_PROJECT_ENDPOINT and AZURE_AI_AGENT_NAME (both required, throw on missing), derive the agent endpoint with new Uri($"{projectEndpoint}/agents/{agentName}/endpoint/protocols/openai"), then call aiProjectClient.AsAIAgent(agentEndpoint, ...).
* SessionFilesClient README updated.
Contributor samples (responses/*):
* New HostedContributorRouteExtensions.MapDevTemporaryLocalAgentEndpoint() wildcard route extension so localhost contributor servers accept the per-agent OpenAI endpoint shape the production Hosted runtime exposes.
* All 11 contributor Program.cs files call MapDevTemporaryLocalAgentEndpoint() with a contributor-only warning comment.
* Hosted-Files and Hosted-AzureSearchRag were importing Hosted_Shared_Contributor_Setup but never calling AddDevTemporaryLocalContributorSetup(). Both now call it so HostedSessionIsolationKeyProvider resolves correctly in dev.
* Hosted-AzureSearchRag, Hosted-Files, Hosted-MemoryAgent csprojs drop stale VersionOverride="2.1.0-beta.1" pins.
* Hosted-AzureSearchRag and Hosted-Files csprojs add ProjectReference to Hosted_Shared_Contributor_Setup.
* Hosted-Observability/.dockerignore removed the out/ exclusion that was blocking COPY out/ . in Dockerfile.contributor.
Verified:
* Full solution-scoped build of changed projects: green.
* Scoped CI-parity dotnet format via WSL2 + Docker (mcr.microsoft.com/dotnet/sdk:10.0) over every changed csproj: clean.
* Foundry unit tests: 263/263.
* Contributor docker smoke for 8 hosted samples (publish + docker build + docker run + curl POST to the wildcard route): HTTP 200 / 500 with route matched.
* End-to-end smoke against the real Azure Foundry project with a fresh bearer token: Hosted-Files contributor container served HTTP 200, the agent invoked ListBundledFiles, and returned the expected file name.
* Address PR review: forward pipeline settings; add UTs
- CreateProjectClientOptions also carries RetryPolicy, NetworkTimeout, ClientLoggingOptions, MessageLoggingPolicy (was Transport+UserAgentApplicationId only).
- Make CreateProjectClientOptions internal so tests can verify the copy directly.
- Add AsAIAgent(Uri) UTs covering tools forwarding to inner ChatOptions and null tools handling.
- Add CreateProjectClientOptions UTs covering null caller and full pipeline-settings copy.
* Fix GitHubCopilotAgent ignoring tools from context providers (#5736)
_create_session and _resume_session only forwarded self._tools (constructor
tools) to CopilotClient.create_session, dropping any tools contributed by
context providers via session_context.extend_tools() during before_run.
Merge provider-contributed tools into runtime_options in both _run_impl and
_stream_updates before session creation, mirroring how RawAgent handles the
merge at lines 1435-1440 in _agents.py. Update _create_session and
_resume_session to combine self._tools with the merged runtime tools.

* Python: Fix GitHubCopilotAgent to include tools added by ContextProvider.before_run in session creation
Fixes#5736
* Fix provider tool merge to avoid mutating caller's list
- Replace in-place .extend() with fresh list creation in both
_run_impl and _stream_updates paths to prevent mutating the
caller-provided options['tools'] list (shallow copy issue)
- Also handles immutable Sequence types (e.g. tuple) correctly
- Add test for provider tools forwarded via _resume_session path

The frontmatter parser previously matched only single-line `key: value` pairs, so block scalar indicators (`|` literal, `>` folded, with chomping `-`/`+`) were silently truncated to the indicator character. Multi-line descriptions like `description: >\n ...` lost their content.
Add `_parse_yaml_scalar_value()` which detects block scalar indicators, collects indented continuation lines, strips the common leading indentation, joins per scalar style (newlines for `|`, spaces for `>`), and applies chomping per the YAML 1.2 spec. Update `_extract_frontmatter()` to use the helper for unquoted values.
Adds 15 unit tests covering literal/folded styles, all chomping variants, indentation handling, content containing colons, non-description fields, tab indentation, blank-line preservation, and a regression test for plain values.
Fixes#5713.

* .NET: Add Hosted-MemoryAgent sample with isolation key plumbing (#5692)
Adds HostedSessionContext + HostedSessionIsolationKeyProvider in Microsoft.Agents.AI.Foundry.Hosting so AIContextProviders (notably FoundryMemoryProvider) can scope per user via the platform's x-agent-user-isolation-key / x-agent-chat-isolation-key headers.
- New types: HostedSessionContext (sealed), HostedSessionContextExtensions (public Get, internal Set), abstract HostedSessionIsolationKeyProvider (async), internal PlatformHostedSessionIsolationKeyProvider mapping ResponseContext.Isolation.
- AgentFrameworkResponseHandler now resolves the provider, tags fresh sessions, and validates resumed sessions against the live request (strict 403 'Hosted session identity context mismatch' on any mismatch; 500 on null keys).
- New shared sample project Hosted_Shared_Contributor_Setup hosts DevTemporaryTokenCredential and DevTemporaryLocalSessionIsolationKeyProvider plus AddDevTemporaryLocalContributorSetup. All 9 existing responses samples migrated to consume it so local runs keep working under the strict isolation contract.
- New Hosted-MemoryAgent sample: travel assistant wired through FoundryMemoryProvider with stateInitializer reading session.GetHostedContext().UserId. Includes Dockerfile, smoke.ps1, agent.yaml/manifest.
- New IT scenario 'memory' in Foundry.Hosting.IntegrationTests + MemoryHostedAgentFixture + MemoryHostedAgentTests. Verified end to end against the tao Foundry project.
- ADR 0026 captures the design tree.
* Address PR review feedback
- Dockerfile: add header noting it targets NuGet builds; contributors must use Dockerfile.contributor for ProjectReference source builds.
- PlatformHostedSessionIsolationKeyProvider: doc said 'returns context with empty values'; corrected to 'returns null' which the handler treats as 500.
- FakeHostedSessionIsolationKeyProvider: doc clarifies that null configurations are allowed for testing the handler error path.
- HostedSessionContextExtensions.SetHostedContext: enforce write-once with InvalidOperationException; doc + xml exception updated.
- AgentFrameworkResponseHandler: cache PlatformHostedSessionIsolationKeyProvider as static readonly to avoid per-request allocation.
- MemoryHostedAgentTests: tighten waits from 20s to 5s (FoundryMemoryProvider defaults UpdateDelay=0; ingestion ~3s).
- Sample Program.cs imports reordered to satisfy IDE0005.
* Add HostedFoundryMemoryProviderScopes built-in helpers (#5692)
Addresses review feedback from @lokitoth on Hosted-MemoryAgent/Program.cs:54.
- New HostedFoundryMemoryProviderScopes static class with PerUser, PerChat, PerUserAndChat factories returning Func<AgentSession?, FoundryMemoryProvider.State>.
- All helpers throw InvalidOperationException when GetHostedContext() is null, with a message pointing at writing a custom stateInitializer for non-hosted scenarios.
- New HostedFoundryMemoryScope enum and AddHostedFoundryMemoryProvider DI extension (two overloads: explicit AIProjectClient and DI-resolved). Singleton lifetime. Default scope = PerUser.
- Hosted-MemoryAgent sample and the memory IT scenario container both swap their inline lambdas for HostedFoundryMemoryProviderScopes.PerUser().
- 14 new unit tests (241/241 hosting unit tests pass).
* Replace HostedFoundryMemoryScope enum with Func<...> parameter (#5692)
Address PR review feedback from @westey-m: enums are a breaking-change hazard when extended, and the enum was redundant with the existing HostedFoundryMemoryProviderScopes static class.
- Delete HostedFoundryMemoryScope.cs.
- AddHostedFoundryMemoryProvider DI extensions now take Func<AgentSession?, FoundryMemoryProvider.State>? stateInitializer = null. When null, default to HostedFoundryMemoryProviderScopes.PerUser().
- Callers pick a built-in helper (PerUser/PerChat/PerUserAndChat) or pass a custom delegate. New built-ins are a single static method addition with zero impact on existing callers.
- Tests updated; 244/244 hosting unit tests pass.
* Fix isolation context resume for externally-created conversations (#5692)
Branch on the session's existing hosted-context (not on conversation_id presence) so a conversation provisioned externally (e.g. via conversations.CreateProjectConversationAsync) is treated as fresh on first hosted-agent request and stamped, rather than rejected with 403 hosted_session_identity_mismatch. Strict equality is preserved on real resume of an already-stamped session.
Also tighten dotnet/global.json to version 10.0.204 + rollForward latestPatch so local builds match the CI Docker image SDK and avoid 10.0.300 dotnet format stripping required usings.
* Revert global.json SDK pin to upstream (#5692)
The 10.0.204 + latestPatch pin from the previous commit broke the dotnet-format CI job (hostfxr_resolve_sdk2 could not find a compatible SDK in the mcr.microsoft.com/dotnet/sdk:10.0 image). Restore upstream 10.0.200 + minor; local Release builds with SDK 10.0.300 should set GITHUB_ACTIONS=true to bypass the auto-format-on-build target.

TestServerWithDevUI_ResolvesMixedAgentsAndWorkflows_AllRegistrationsAsync fails intermittently in the merge_group with NRE on the discovery response, blocking PRs unrelated to DevUI from merging. Skip via Fact(Skip=...) referencing #5845 while the underlying race is investigated.
* Python: DevUI: tighten default access controls and CORS posture
Adjusts the default configuration of the DevUI server so the out-of-the-box
posture matches what most callers expect when running locally. Adds explicit
opt-outs for callers who need the previous behavior.
- DevServer gains auth_enabled and auth_token constructor params; auth is on by
default. Auto-generates and logs a token when none provided.
- CORS default is an empty allowlist on every host. Callers wanting cross-origin
pass cors_origins explicitly.
- Streaming /v1/responses no longer sets Access-Control-Allow-Origin directly;
CORSMiddleware owns all CORS decisions.
- Loopback binds enforce a Host-header allowlist.
- /meta moved out of the auth bypass list (was alongside /health and /).
- serve() default flipped to auth_enabled=True; passes auth args through to
DevServer instead of using env-var indirection.
- CLI: --auth opt-in replaced with --no-auth opt-out; --auth-token preserved.
- Tests cover the eight behaviors above in test_server.py.
* Python: DevUI: address PR review comments
- /meta now derives auth_required from self.auth_enabled instead of
reading DEVUI_AUTH_TOKEN, so the auto-generated and explicit
auth_token paths report correctly.
- Reorder middleware so the loopback Host-header allowlist is registered
last; Starlette wraps later-added middleware around earlier-added ones,
so the host check now runs outermost (before CORS/auth) as intended.
- Rework comments to describe the behavior rather than threat scenarios.
- Streaming-headers and CORS tests now construct the server with an
explicit auth_token and send a Bearer header, so the assertions
actually exercise the streaming/CORS path instead of short-circuiting
in the auth middleware.
Replaces two ILogger.LogWarning(string, params object?[]) calls in DevUIAuthFilter and DevUIExtensions with allocation-free [LoggerMessage] partial methods on a new internal DevUILog class. Preserves original message templates and structured property names ({RemoteIp}, {EnvVar}).

Fixes microsoft/agent-framework#3295. When the OpenAI Responses chat
client sends a request that carries previous_response_id / conversation_id
/ conversation, the server already has the prior turn's response items
and rejects duplicates with "Duplicate item found with id fc_xxx". The
chat client was re-sending them inline whenever the input messages still
carried the items in additional_properties (workflow replay, history
providers, etc.), which broke any tool-using agent with persistent
history.
Decisions:
- Single chokepoint: _prepare_message_for_openai. When the resulting
request uses service-side storage, drop function_call, reasoning,
approval-request/response, and local-shell-call items from the wire
input. Keep function_result with its call_id; the server pairs it to
the prior function_call via that key.
- function_result is preserved unconditionally except for the local-shell
variant, which carries its own server-issued item id.
- No public API change. Wire format change is subtractive and only on
requests that would otherwise 400.
- Re-pointed the strict-xfail in test_full_conversation.py from #4047 to
#3295. Kept xfail because the test asserts executor-level session-id
clearing, which is the defense-in-depth half tracked by 3295-03; this
slice closes the wire-level half.
Files:
- python/packages/openai/agent_framework_openai/_chat_client.py: strip
rule applied alongside the existing reasoning-item branch.
- python/packages/openai/tests/openai/test_openai_chat_client.py: four
new tests pin the contract (function_call, approval, local-shell-call
stripped under storage; everything kept without storage). Updated
pre-existing tests that exercised the storage-on path to either pass
request_uses_service_side_storage=False explicitly or assert the new
strip behavior.
- python/packages/foundry/tests/foundry/test_foundry_chat_client.py:
same explicit storage-off opt-in for the inherited test.
- python/packages/core/tests/workflow/test_full_conversation.py:
re-pointed xfail reason to #3295 and the executor-level follow-up.
Notes for next iteration:
- 3295-01 (HITL wire-format validation against live OpenAI/Foundry) was
not run; it requires the user's API credentials. The PRD design is
locked but the empirical confirmation is still pending. If script 3
fails on either provider, this slice may need to be revisited.
- 3295-03 (clear service_session_id in AgentExecutor on full-history
replay) remains open. After it lands the xfail in
test_full_conversation.py can be removed.
- pytest was not run in this iteration because uv-based pytest commands
required interactive approval. Validation rests on careful reading;
next iteration should run the openai + core test suites.

* fix(python): prevent MCP message_handler deadlock on notification reload
When an MCP server sends a notifications/tools/list_changed or
notifications/prompts/list_changed notification, the message_handler
previously awaited load_tools()/load_prompts() directly. Since the
handler runs on the MCP SDK's single-threaded receive loop, this
caused a deadlock: load_tools() sends a list_tools request and waits
for its response, but the receive loop cannot deliver that response
while blocked in the handler.
This manifested as a timeout in call_tool(), which then surfaced as
"Error: Function failed." to the model instead of the real tool
output. The MATLAB MCP server reliably triggers this because it sends
a tools/list_changed notification during tool execution.
Fix: schedule reloads as background asyncio.Tasks via a new
_schedule_reload() helper, freeing the receive loop immediately.

* fix: address review comments on MCP reload handling
- Fix exc_info=True -> exc_info=message in message_handler error logging,
since the handler is not called from an except block
- Await cancelled reload tasks in _close_on_owner before tearing down
the session to avoid 'Task was destroyed but pending' warnings

* .NET: feat(evals): add ground_truth/expected_output support for workflow eval
Brings .NET to parity with Python PR #5234 for issue #5135:
- Add expectedOutput parameter to Run.EvaluateAsync (workflow) and stamp on the overall EvalItem.ExpectedOutput.
- Map EvalItem.ExpectedOutput -> ground_truth in the Foundry JSONL payload, item_schema, and data_mapping for similarity.
- Add GroundTruthEvaluators set (currently builtin.similarity) and a FindMissingGroundTruthEvaluators helper.
- Fail fast with InvalidOperationException when a ground-truth evaluator is selected but no item provides an ExpectedOutput, instead of surfacing a remote provider error.
- Add tests in FoundryEvalConverterTests and WorkflowEvaluationTests.
- Add Evaluation_WorkflowExpectedOutputs sample (workflow + Foundry similarity).
Fixesmicrosoft/agent-framework#5135 (.NET side).

* Address review: relax BuildOverallItem events to IReadOnlyList<WorkflowEvent>
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* Sample: disable per-agent breakdown when using reference-based evaluator
Per-agent EvalItems are intentionally left without ExpectedOutput, so the new fail-fast validation in FoundryEvals would throw when Similarity is invoked for per-agent items. Pass includePerAgent: false in the workflow + similarity sample, and document this gotcha in the EvaluateAsync XML doc.

* Fix BuildOverallItem: fall back to last ExecutorCompletedEvent
AgentResponseEvent is only emitted when AIAgentHostOptions.EmitAgentResponseEvents is enabled, which is not the default for WorkflowBuilder(agent).AddEdge(...). When it is absent, fall back to the last non-internal ExecutorCompletedEvent whose Data is an AgentResponse / ChatMessage / string so the overall EvalItem (and any expectedOutput) is produced. Without this, samples wired up the standard way returned 0 evaluation items.
Update test to cover the fallback path.
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* Sample: enable EmitAgentResponseEvents; eval throws clear error when no overall response found
Root cause of '0 results': AIAgentHostExecutor only emits AgentResponseEvent when AIAgentHostOptions.EmitAgentResponseEvents is true (default false). For ordinary AIAgent executors the runtime's ExecutorCompletedEvent.Data is null, so the prior fallback couldn't find a final response either.
Sample now builds executors with EmitAgentResponseEvents=true via BindAsExecutor(hostOptions). EvaluateAsync now throws InvalidOperationException with a remediation hint when the user supplies expectedOutput but no overall final response can be located, instead of silently returning 0/0.
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* Guard against null sample/error/usage/datasource_item in ParseDetailedItem
Foundry eval responses can have these properties present with JSON null
or non-object values, which caused JsonElement.TryGetProperty to throw
'requires Object, has Null'. Check ValueKind == Object before drilling in.
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* Address PR review: reorder expectedOutput, tighten ground-truth check, add fail-fast test
* WorkflowEvaluationExtensions.EvaluateAsync: move 'expectedOutput' to
after 'splitter' so the original positional contract of (splitter,
cancellationToken) is preserved for existing callers.
* FoundryEvals: require ALL items to carry ExpectedOutput when a
ground-truth evaluator is selected (e.g. similarity), not just any.
Reference-based evaluators score per-item, so a single missing GT
would still surface as a provider-side validation error. Updated
fail-fast message accordingly.
* WorkflowEvaluationTests: add EvaluateAsync_WithExpectedOutputButNoFinalResponse_ThrowsAsync
to verify the InvalidOperationException is thrown (and that the
message mentions EmitAgentResponseEvents).
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* Fail-fast on missing overall item regardless of expectedOutput; harden BuildOverallItem default
* EvaluateAsync now throws InvalidOperationException whenever 'includeOverall'
is requested but BuildOverallItem cannot produce an item, instead of only
when 'expectedOutput' is supplied. Same misconfiguration (agents not bound
with EmitAgentResponseEvents) used to silently return empty results — now
it surfaces a clear, actionable error in both cases.
* BuildOverallItem switch default now throws instead of returning null. The
preceding for-loop already constrains Data to AgentResponse/ChatMessage/
string, so reaching default would indicate a contract drift; throw to make
the bug visible.
* Test renamed and broadened to verify the throw fires without expectedOutput.

* .NET: OpenTelemetryAgent normalize sourceName once and add OTEL wiring path coverage
Normalize the configured source name once in the constructor so the outer OpenTelemetryChatClient and the auto-wired inner OpenTelemetryChatClient always emit spans on the same ActivitySource. A caller passing an empty string previously produced agent-level spans on DefaultSourceName but auto-wired chat spans on the empty source, causing the chat spans to be silently dropped by exporters subscribed to the default source.
Tests added to cover the previously unexercised OTEL wiring branches:
- Ctor_NullOrEmptySourceName_AutoWiredChatClientUsesDefaultSource_Async (Theory: null and empty)
- AutoWireChatClient_PlainAgentRunOptions_PreservesContinuationToken_Async
- AutoWireChatClient_ChatClientAgentRunOptions_NoUserFactory_PreservesChatOptions_Async
- AutoWireChatClient_StreamingDisabled_DoesNotEmitChatSpan_Async
* .NET: Mark OpenTelemetryAgent autoWireChatClient ctor as [Experimental]
Annotate the new 3-arg OpenTelemetryAgent(AIAgent, string?, bool) constructor with [Experimental(DiagnosticIds.Experiments.AgentsAIExperiments)] (MAAI001) so callers must explicitly opt in to the auto-wire toggle. The original 2-arg constructor stays non-experimental and delegates with autoWireChatClient: true; the delegating call is locally suppressed so the existing source compatibility surface is preserved.
* .NET: OpenTelemetryAgent address westey-m PR review
- Use string.IsNullOrWhiteSpace (not IsNullOrEmpty) when normalizing the constructor sourceName, so callers passing whitespace-only strings still land on OpenTelemetryConsts.DefaultSourceName instead of an unsubscribed ActivitySource.
- Fix the misleading pragma comment on the 2-arg ctor delegating call: auto-wiring is the new default, it does not preserve the original (pre-PR) behavior.
- Expand the GetRunOptionsWithChatClientWiring XML doc to spell out that a base AgentRunOptions (not ChatClientAgentRunOptions) is also accepted: it is converted to ChatClientAgentRunOptions with the auto-wire factory installed and base properties copied.
- Tests: extend the source-name normalization Theory with whitespace cases (' ' and '\t'); add end-to-end coverage for plain AgentRunOptions over a real ChatClientAgent (sync + streaming) asserting the inner chat client is invoked and both invoke_agent + chat spans are emitted.

The upsidr/merge-gatekeeper@v1 action is a Dockerfile-based action that
builds a golang image on every run. On merge_group events the run step
is conditioned out via `if: github.event_name == 'pull_request'`, so the
build happens but produces nothing.
Replace with an actions/github-script@v8 polling loop that mirrors the
action's behavior exactly: merges combined-statuses and check-runs for
the PR head SHA, with combined-status winning on name collisions, and
the same conclusion mapping (skipped → dropped, success/neutral →
success, anything else terminal → error). Same job name, triggers,
permissions, timeout (3600s), interval (30s), and ignored list, so
existing required-check rules stay valid.
PR runs now poll the API in seconds instead of waiting on a per-run
docker image build, and merge_group runs become near-instant no-ops.
* Python: add ag-ui tool result display channel
Key decisions:
- Add TOOL_RESULT_DISPLAY_KEY and make state_update accept optional state plus a tool_result display payload.

to 0 and failed with 'Response count greater than expected: 0 (Actual: 1)'.
Updated to expect exactly 1 response, matching the SendActivity pattern.

* Fix OpenAIResponsesAgentClient endpoint to include agentName in path (#5324)
The sample OpenAIResponsesAgentClient used '/v1/' as the endpoint, which
routes to the multi-agent endpoint requiring agent.name in the request body.
However, AsIChatClient(agentName) maps agentName to the model field, not
agent.name, causing HTTP 400 errors on OpenAI-compatible endpoints.
Changed the endpoint to '/{agentName}/v1/' to match the pattern used by
OpenAIChatCompletionsAgentClient, routing to the single-agent endpoint
where no agent.name body field is needed.
Added regression test verifying that the model field alone is insufficient
for agent resolution on the multi-agent endpoint.

* Address review feedback for #5324
- URL-escape agentName in OpenAIResponsesAgentClient endpoint path to

* feat(dotnet): add Microsoft.Agents.AI.Tools.Shell with LocalShellTool
Ports Python LocalShellTool to .NET as a new package (net8/9/10).
- Microsoft.Agents.AI.Tools.Shell: LocalShellTool, ShellPolicy (deny-list
guardrail), ShellResolver (cross-OS pwsh/powershell/cmd vs bash/sh),
ShellResult with head+tail truncation, timeout + process-tree kill,
AsAIFunction with required-by-default human approval gate.
- Persistent mode via ShellSession (sentinel protocol over pwsh/bash).
- acknowledgeUnsafe parity gate matches the Python implementation.
- Auto-injected platform context in the AIFunction description so the
LLM sees the active OS and shell at tool-discovery time.
- 17 xunit.v3 tests cover policy allow/deny, echo roundtrip, exit
codes, timeout/kill, AsAIFunction shape + approval wrapping,
persistent cwd/env carry-over, head+tail truncation, sentinel race.

* feat(shell): close Python parity gaps for LocalShellTool
Closes the .NET vs Python parity gaps identified in the competitive eval:
- Default mode flipped to ShellMode.Persistent (matches Python). Every
call now reuses a long-lived shell so cd/exports/functions persist;
pass mode: ShellMode.Stateless to opt out.
- New IShellExecutor interface — pluggable backend so future
DockerShellTool / Hyperlight / SSH executors don't fork the framework.
LocalShellTool implements it.
- Workdir confinement: confineWorkingDirectory (default true) re-anchors
every persistent-mode command back to workingDirectory so a wandering
cd in one call doesn't leak to the next. Mirrors Python _maybe_reanchor.
- Graceful interrupt on timeout: ShellSession sends SIGINT (POSIX) or
Ctrl+C-on-stdin (Windows) before falling back to a hard close+respawn.
Successfully-interrupted commands return exit 124 + TimedOut=true while
preserving session state for the next call.
- cleanEnvironment opt-in: when true, only PATH/HOME/USER/USERNAME/
USERPROFILE/SystemRoot/TEMP/TMP plus user-supplied vars are visible.
- shellArgv: IReadOnlyList<string> override accepted alongside the
string shell binary param (mutually exclusive). Lets advanced callers
inject flags like --rcfile or --login.
- Typed exceptions ShellTimeoutException and ShellExecutionException
replace InvalidOperationException for launch / liveness failures.
Tests: 17 -> 23. New cases cover persistent-default ctor, mutually-
exclusive shell/shellArgv, confined re-anchor, confine-disabled leak,
clean-env strip, and IShellExecutor implementation. All green on net10.0.

* feat(shell): add DockerShellTool sandboxed shell tier
Ports the Python DockerShellTool to .NET. Mirrors the public surface of
LocalShellTool but executes commands inside an isolated container, where
the container is the security boundary. Stateless and persistent modes
both supported; persistent mode reuses ShellSession by launching
'docker exec -i <ctr> bash --noprofile --norc' as the long-lived REPL,
so the sentinel protocol works unchanged.
Defaults chosen for safety:
- --network none, --user 65534:65534 (nobody), --read-only root
- --cap-drop=ALL, --security-opt=no-new-privileges
- 512m memory cap, pids-limit 256, --tmpfs /tmp
- Optional host workdir mount, ro by default
Public surface:
- DockerShellTool ctor with image/container_name/mode/host_workdir/
workdir/network/memory/pids_limit/user/read_only_root/extra_run_args/
environment/policy/timeout/max_output_bytes/on_command/docker_binary
- StartAsync, CloseAsync, RunAsync, AsAIFunction, IShellExecutor impl
- IsAvailableAsync(binary) probe
- Static argv builders (BuildRunArgv, BuildExecArgv) — pure, side-
effect free, so unit tests don't need a Docker daemon
AsAIFunction defaults to requireApproval: false (the container IS the
boundary). LocalShellTool keeps the opposite default.
Tests: 23 -> 35. 12 new tests cover argv builders, env/extra-args/host-
workdir flags, exec interactive vs stateless, container name uniqueness,
IShellExecutor implementation, AsAIFunction approval defaults, and
IsAvailableAsync false-path. None require Docker. Multi-TFM build
(net8/9/10) green.

* test(shell): add DockerShellTool integration tests
Adds 9 end-to-end tests that exercise DockerShellTool against a live
Docker (or Podman) daemon. Tests are tagged [Trait("Category",
"Integration")] and auto-skip via Assert.Skip when no daemon is
available, so they are CI-safe.
Coverage:
- IsAvailableAsync probe
- Persistent mode basic command + state preservation across calls
- --network none blocks outbound DNS
- --read-only root prevents writes outside /tmp; /tmp tmpfs is writable
- --user 65534:65534 (nobody) is in effect
- Stateless mode: env vars do not leak across calls
- HostWorkdir bind-mount + read-only enforcement
- Environment variables passed via -e
Tests use debian:stable-slim (alpine ships only busybox sh, which
ShellSession persistent bash REPL cannot drive).
Run locally:
dotnet test --filter "Category=Integration"
or filter by class on the test exe directly.

* PR 5604 review fixes (group a): libc DllImport, namespace cleanup, policy-msg dedup
Three quick-win review comments on PR #5604:
1. ShellSession: the libc `killpg` P/Invoke was annotated with
`DllImportSearchPath.System32`, a Windows-only loader hint that does
nothing for libc.so on POSIX. Switched to `SafeDirectories` (CA5392
/CA5393 clean) and added a comment noting the call site is gated to
non-Windows.
2. DockerShellToolTests: replaced the fully-qualified
`Extensions.AI.ApprovalRequiredAIFunction` with a `using
Microsoft.Extensions.AI;` import and the bare type name, matching
`LocalShellToolTests`.
3. LocalShellTool / DockerShellTool: `AsAIFunction`'s catch block was
producing a doubled "Command blocked by policy: Command rejected by
policy: ..." prefix because the `ShellPolicyException` message
already starts with "Command rejected by policy". Now we return
`ex.Message` directly.

* PR 5604 review fix (group b): add ShellKind.Sh for /bin/sh fallback
Review comment (#3): when /bin/bash is missing the resolver fell back to
/bin/sh but tagged it as ShellKind.Bash, so the launcher passed bash-only
flags --noprofile --norc to dash/ash/busybox, which interpret them as
positional script names.
Fix:
* Added ShellKind.Sh for minimal POSIX shells (sh, dash, ash, busybox).
* /bin/sh fallback is now tagged Sh.
* ClassifyKind maps "SH" / "DASH" / "ASH" / "BUSYBOX" binary names to Sh.
* StatelessArgvForCommand emits just `-c <command>` for Sh (no
bash-only flags); PersistentArgv emits no flags at all.
* LocalShellTool's system-prompt builder describes Sh distinctly and
warns the model away from bash-only constructs.
Tests: ShellResolverTests covers Sh/Bash classification through the
observable argv output (14 new theory cases). Total: 58/58.

* PR 5604 review fix (group d): honor timeout=null, add DefaultTimeout
Review comment (#5): both LocalShellTool and DockerShellTool documented
`timeout: null` as "disables timeouts" but the constructor coerced null
to 30 seconds, making the documented disable mechanism unreachable
through the public API.
Fix:
* Drop the `?? TimeSpan.FromSeconds(30)` coercion in both ctors.
`_timeout` now faithfully reflects what the caller passed (null =
disabled). The downstream CTS-construction sites already short-circuit
on null, so no other code changes are required.
* Add `public static readonly TimeSpan DefaultTimeout` (30 s) on both
tools so callers who want a bounded timeout can opt in explicitly.
Tests:
* New `RunAsync_NullTimeout_DoesNotTimeOutAsync` confirms a quick
command runs to completion when the caller passes `timeout: null`.
* New `DefaultTimeout_IsThirtySeconds` documents the constant.
Behavioral note: this is a deliberate change-of-default. Callers that
previously omitted `timeout` and relied on the implicit 30 s now get
"no timeout". They should pass `LocalShellTool.DefaultTimeout` or
`DockerShellTool.DefaultTimeout` explicitly to preserve the prior
behavior.

* PR 5604 review fix (group e): smart requireApproval default for DockerShellTool
Review comment (#6, design): requireApproval: false baked in a
safety decision the type cannot prove on its own. Callers can
weaken any isolation knob (network, user, readOnlyRoot, mount,
extraRunArgs) and still get an unapproved tool by default.
Fix:
* New public IsHardenedConfiguration property returns true iff the
effective config matches the safe defaults: network=="none",
non-root user, read-only root, host mount (if any) read-only,
no extra run args.
* AsAIFunction's requireApproval parameter is now bool? defaulting
to null. When null, approval is enabled iff
IsHardenedConfiguration is false. Pass false explicitly to opt
out, or true to force.
* docker-shell-tool.md updated with the new approval matrix.
Tests: 4 new theory cases + 2 facts cover hardened-default,
relaxed-network, root-user, writable-root, extraRunArgs, and
explicit-opt-out branches. Total: 66/66.

* PR 5604 review fix (group c): wrap POSIX shell in setsid for correct killpg
Review comment (#1): killpg(proc.Id, SIGINT) only behaves like a
process-group signal when proc.Id IS a process group id. Since the
.NET launcher does not call setsid() / setpgid() itself, the spawned
shell inherits the agent host's process group — so killpg targeted
the wrong group and the cancel signal could leak to the agent.
Fix:
* On non-Windows, EnsureStartedAsync probes for setsid (well-known
paths first, then PATH). When found it wraps the shell launch as
`setsid <shell> <args...>` so the spawned shell becomes a session
leader (PID == PGID).
* A new _isSessionLeader flag tracks whether the wrap succeeded.
* InterruptCurrentCommandAsync only calls killpg when
_isSessionLeader is true. Without setsid, killpg on an unsuited
PID could signal the agent itself, so we skip the fast path and
let the caller's hard close-and-respawn handle the timeout.
* Windows behaviour is unchanged (Ctrl+C-via-stdin to pwsh).
No public-API changes; existing tests cover the interrupt path and
all 66/66 still pass.

* .Net: DockerShellTool design + caller-cancel container leak fixes (PR #5604)
Addresses three Copilot review findings on PR #5604.
Design (group f):
* StartAsync: change inner ResolvedShell from ShellKind.Bash to ShellKind.Sh.
BuildExecArgv() already includes `--noprofile --norc` in ExtraArgv;
Bash's PersistentArgv() was appending those flags a second time,
yielding `bash --noprofile --norc --noprofile --norc`. Sh's
PersistentArgv() returns Array.Empty so ExtraArgv is forwarded
unchanged.
* BuildExecArgv: remove the dead `interactive: false` branch and the
`interactive` parameter. The `false` path produced an unusable argv
ending in `-c` with no command and was never invoked internally
(stateless mode uses BuildRunArgvStateless). Updated tests and
docs/docker-shell-tool.md sequence diagram.
Reliability (group g):
* RunStatelessAsync: add a second `catch (OperationCanceledException)`
guarded on `cancellationToken.IsCancellationRequested` that issues
`docker kill --signal KILL <perCallName>` before rethrowing.
Previously, caller-driven cancellation bypassed the timeout-only
catch and propagated without killing the container; because `--rm`
only fires when PID 1 exits, the container ran indefinitely.
Extracted the kill-by-name logic into a `BestEffortKillContainerAsync`
helper shared by both the timeout and caller-cancel paths.

* .Net: Fill PR #5604 test coverage gaps for Shell tools
Addresses the test-coverage findings in the latest Copilot review.
* ShellResultTests (new): direct branch coverage for
ShellResult.FormatForModel() — empty stdout, non-empty stderr,
truncated, timed-out, success, and the truncated-with-empty-stdout
edge where the marker is intentionally suppressed. This method's
string is what the language model sees, so it benefits from
explicit unit-level coverage independent of integration tests.
* ShellSessionTests (new): direct unit tests for the internal
TruncateHeadTail head-tail truncation utility — under-cap (no
truncation), exactly at cap (no truncation), over-cap (truncated
with marker, both head and tail preserved), and empty-string.
Reachable via InternalsVisibleTo.
* LocalShellToolTests: Theory test exercising 8 representative
patterns from ShellPolicy.DefaultDenyList (rm -rf /, mkfs.ext4,
curl|sh, wget|sh, Remove-Item /, shutdown, reboot, Format-Volume)
to catch deny-list regex regressions; previously only 1/16 was
tested.
* LocalShellToolTests: explicit stderr-capture assertion (echo to
stderr → result.Stderr contains the message). Stderr capture was
not directly asserted anywhere in the suite.
* DockerShellToolTests: RunAsync_RejectedCommand throws
ShellCommandRejectedException. The Docker-side policy check is a
pure-logic path that runs before any docker invocation, so this
test covers the rejection branch without needing a Docker daemon.
Total: 66 -> 85 tests, all passing on net10.0.

* feat(dotnet/shell): add ShellEnvironmentProvider for OS-aware shell instructions
Pairs LocalShellTool/DockerShellTool with an AIContextProvider that
probes the live shell once per session (OS, family, version, CWD,
configurable CLI versions) and injects authoritative instructions so
the agent uses platform-native idioms (PowerShell vs POSIX). Fixes the
class of bugs where the model emits 'VAR=value' / '/tmp' / '$VAR' on
a Windows PowerShell session.
- ShellEnvironmentProvider/Snapshot/Options public surface in the
existing Microsoft.Agents.AI.Tools.Shell package (one new project
reference to Microsoft.Agents.AI.Abstractions).
- Probes go through the same IShellExecutor that runs agent commands,
so they respect the configured policy and (for DockerShellTool) the
container boundary.
- 8 unit tests covering snapshot capture, default formatter idioms,
missing-tool handling, custom formatter override, and refresh.
- Agent_Step21_ShellWithEnvironment sample replays the DEMO_TOKEN
cross-call scenario using a persistent local shell.

* fix(dotnet/shell): address PR review feedback round 3
- ShellEnvironmentProvider.cs split into one-type-per-file (ShellFamily,
ShellEnvironmentSnapshot, ShellEnvironmentProviderOptions, plus the
provider class) to match FoundryMemoryProvider/AgentSkillsProvider
layout.
- csproj: drop IsPackable=false (package will publish on merge), add
IsReleased=true and disable package validation baseline (first release),
use TargetFrameworksCore, add InjectSharedDiagnosticIds and
InjectExperimentalAttributeOnLegacy to align with shipping packages.
- Sample: refactor to demonstrate stateless mode first (independent
read-only commands), then persistent mode (state carried across calls,
e.g. DEMO_TOKEN). Strip narrative/historical comments.
- Move docker-shell-tool.md out of the package — that doc lives in
the docs repo (semantic-kernel-pr/agent-framework, branch
feat/dotnet-shell-tool).

* Address PR #5604 round 4 review feedback
- Sample (Agent_Step21_ShellWithEnvironment): add prominent WARNING block
noting LocalShellTool runs real commands on the host. Restructure sample
to demonstrate stateless mode first (cd does not carry across calls) then
persistent mode (cd and env vars persist), motivating when to pick each.
- DockerShellTool class XML doc: reframe as a best-effort baseline rather
than a security guarantee; list mitigations users should still apply.
- DockerShellTool ShellKind.Sh comment: rephrase as forward-looking design
rationale (avoid duplicate --noprofile/--norc if Bash is reintroduced)
instead of bug-history narrative.
- DockerShellTool.IsHardenedConfiguration / AsAIFunction XML docs: clarify
these are configuration-shape checks and convenience defaults, not
security guarantees.
- Drop IDisposable from LocalShellTool and DockerShellTool. The previous
sync Dispose() blocked on DisposeAsync().GetAwaiter().GetResult() with a
VSTHRD002 suppression, which is fragile under sync contexts. Both tools
now expose IAsyncDisposable only; tests updated to await using.

* Fix CPU busy-spin in WaitForSentinelAsync
When new bytes arrived in the stdout read loop, the producer called
TrySetResult on _stdoutSignal but did not replace it with a fresh TCS.
A consumer looping inside WaitForSentinelAsync would then re-read the
same already-completed TCS, causing WaitAsync(100ms) to return
synchronously every iteration — a tight busy-spin that pinned a core
until the sentinel arrived or the timeout fired.
Swap the signal before completing the old one so the next consumer
iteration observes a fresh (uncompleted) TCS, matching the pattern
already used in ReadExitCodeAsync.

* Remove unused onCommand audit hook from shell tools
The Action<string> onCommand callback was a redundant audit-logging seam:

DockerShellTool keeps the public surface lean.

* Document why ShellEnvironmentProvider uses Instructions, not Messages
Expand the class XML doc to record the design rationale: the shell
environment is stable runtime metadata, not per-turn retrieval, so it
belongs in AIContext.Instructions (matching AgentSkillsProvider).
Messages is reserved for retrieval payloads (TextSearchProvider,
ChatHistoryMemoryProvider). System-role placement also has higher
steering weight and benefits from prompt caching in major providers.

* Address PR #5604 round 5 review feedback
- ShellResolver: classify only `bash` as ShellKind.Bash; sh/zsh/dash/ash/ksh/busybox now route through ShellKind.Sh so bash-only --noprofile/--norc flags are not emitted to shells that reject them. Update enum doc and tests.
- ShellEnvironmentProvider.ProbeToolVersionAsync: validate the tool name against ^[A-Za-z0-9._-]+$ before interpolating into a shell command (prevents injection if ProbeTools is sourced from untrusted config). Fall back to stderr when stdout is empty so CLIs like java/older gcc still report a version. Drop misleading 'quoted' comment.
- ShellSession.TruncateHeadTail: truncate by UTF-8 byte count on rune boundaries, honouring the documented maxOutputBytes contract for non-ASCII output.
- ShellEnvironmentProviderTests: drop reflection on private _options; assert against the options instance the test already owns. Rename misnamed RefreshAsync test to reflect re-probing semantics. Add coverage for invalid tool names and stderr-only version output.
- ShellSessionTests: add multi-byte UTF-8 truncation tests (byte-budget honoured, no rune split, no U+FFFD).
- Move DockerShellToolIntegrationTests.cs from the unit test project into a new Microsoft.Agents.AI.Tools.Shell.IntegrationTests project so 'dotnet test' on the unit suite no longer requires a Docker daemon. Wire the new project into agent-framework-dotnet.slnx.

* Address PR #5604 round 6 review feedback
- ShellSession.MaybeReanchor: switch from double-quoted to single-quoted literal-quoting per shell. Double quotes still expand $VAR, ``, and backticks in both PowerShell and POSIX, so a working directory containing shell metacharacters could trigger command substitution. Add QuotePowerShell (escape ' as '') and QuotePosix (close-and-reopen around ') helpers and route MaybeReanchor through them. Add tests covering ``, $VAR, backticks, and embedded single quotes.
- ShellEnvironmentProvider.RunProbeAsync: narrow the OperationCanceledException filter to `when (!cancellationToken.IsCancellationRequested)` so caller-driven cancellation propagates instead of being silently converted to a null snapshot. Update the class XML doc to call out the distinction. Add tests for both paths (caller cancellation throws, probe-timeout returns null fields).
- DockerShellTool.RunStatelessAsync / RunDockerCommandAsync: replace unbounded StringBuilder accumulators with a shared HeadTailBuffer (extracted from LocalShellTool into its own internal type). Caps memory at roughly maxOutputBytes regardless of how much output a command emits; drops the now-redundant trailing TruncateHeadTail call. RunDockerCommandAsync caps helper-command output at 1 MiB (defends against chatty docker pull progress streams). Add HeadTailBufferTests covering bounded behaviour over 10 MiB of streamed input.

* Address PR #5604 round 7 review feedback
- HeadTailBuffer: switch to UTF-8 byte-aware truncation. The class previously
capped on UTF-16 char count while callers pass _maxOutputBytes, so multi-byte
output could exceed the budget and head/tail boundaries could split surrogate
pairs into orphaned halves. Now tracks UTF-8 byte counts and treats each rune
as an indivisible unit (encode -> bytes -> head/tail), guaranteeing the final
string round-trips through UTF-8 and never contains an unpaired surrogate.
The truncation marker now reads `bytes` instead of `chars` to match.
- ShellEnvironmentProvider: clear cached _snapshotTask on failure. Previously a
faulted/cancelled first probe permanently poisoned the provider — every later
ProvideAIContextAsync await replayed the same exception. Now the failed task
is cleared via a CompareExchange so the next caller starts a fresh probe.
Tests: added rune-boundary coverage for HeadTailBuffer, plus two regression
tests for poison-recovery (executor-throw and caller-cancellation paths).

* Address PR #5604 round 8 review feedback
- HeadTailBuffer odd-cap data loss: previously _halfCap = cap / 2 was used as
both the head fill bound and the tail eviction threshold, so an odd cap (e.g.
cap=5 -> halfCap=2) would silently drop a byte while ToFinalString still
reported truncated == false. Split into _headCap = cap / 2 and _tailCap =
cap - _headCap so head + tail budgets always sum to exactly cap; any input
whose UTF-8 size is <= cap now round-trips losslessly.
- ShellSession.TakePrefixByBytes unpaired-high-surrogate: the prefix walker
advanced 2 chars whenever it saw a high surrogate, without verifying that the
next char was actually a low surrogate. Mirrored the pair check from
TakeSuffixByBytes so unpaired surrogates are treated as a single (invalid)
BMP char and the encoder substitutes U+FFFD as it would anywhere else.
- Centralize clean-environment preserved-vars list. The {PATH, HOME, USER,
USERNAME, USERPROFILE, SystemRoot, TEMP, TMP} allowlist was duplicated in
LocalShellTool (stateless launch) and ShellSession (persistent startup), so
adding a new variable required touching both. Extracted into
CleanEnvironmentHelper.PreservedVariables / ApplyPreserved; both call sites
collapse to a single line.
Tests: HeadTailBuffer round-trip-at-odd-cap regression, ShellSession unpaired-
surrogate test.

- ShellSession.TruncateHeadTail odd-cap budget: same fix applied to
HeadTailBuffer last round but missed here. Use headCap = cap/2 +
tailCap = cap - headCap so the head/tail budgets sum to exactly cap.
- Replace TakePrefixByBytes / TakeSuffixByBytes Encoder.Convert loops with
rune iteration. The old code ignored Encoder.charsUsed and trusted the
caller's hand-rolled surrogate-pair detection, which made the byte count
fragile around unpaired surrogates. EnumerateRunes + Utf8SequenceLength
is stateless and self-evidently correct.
- ShellEnvironmentProvider.ProbeAsync now skips case-insensitive duplicates
in the user-supplied ProbeTools list. Previously {\"git\",\"GIT\"} would
probe twice and rely on insertion order to determine the kept value.
- DockerShellToolTests.AsAIFunction_RelaxedConfig_DefaultsToApprovalGated:

IOException, which is the natural .NET shape for these failures.

* Document single-session ownership for persistent shell mode
Several PR #5604 review threads (notably AaQh2) raised that the persistent
shell experience has no concurrency story. The framework's actual design
is "one executor per conversation" — there is no per-caller isolation —
but that contract was only stated briefly on ShellExecutor and not at all
on the types and properties developers reach for first.
Strengthen the docs in the places a user is most likely to land:
- ShellMode.Persistent: explicit single-session-ownership paragraph
(state visible across calls, single pipe, no isolation, one per session).
- ShellExecutor: rewrite the Concurrency paragraph to enumerate what
leaks (cwd, env, history, background jobs) and call out DI scoping.
- LocalShellExecutor: new Single-session-ownership paragraph mirroring
the executor-level contract and pointing at Stateless mode as the
escape hatch.
- DockerShellExecutor: same, framed around the container + bash REPL
the persistent-mode executor owns end-to-end.
- ShellSession: add a Single-owner paragraph on the type docs and a
comment on _runLock clarifying that it serializes the owner's calls,
not multiple tenants.
- LocalShellExecutorOptions.Mode / DockerShellExecutorOptions.Mode:
per-property note pointing at the executor remarks.
Docs-only; src builds clean with zero warnings, zero errors.

* test: Split out Handoff Orchestration tests
* fix: Synthesized Handoff FunctionResult is never sent to agent
When we receive a handoff request from the agent, we need to service it outside of the Agent Loop to terminate the loop. What this means is that we take ownership of terminating the call by feeding the result back into the agent on a subsequent invocation.
When we refactored Handoff to support HITL and make use of AgentSession, we inadvertantly removed this step, causing subsequent invocations to the Handoff agent to fail (first works, but breaks the state).
The fix is to be more precise about the agent's bookmark when concatenating the result of agent invocation to the shared conversation history.

`AgentTask` and `TaskStatusUpdateEvent` mappings.
- Link follow-up messages containing `A2AInputResponseContent` to the
existing task via `TaskId` instead of `ReferenceTaskIds`.
- Add `A2AAgent_HumanInTheLoop` sample and register it in the solution

* .NET: DevUI: add configurable access controls for the DevUI HTTP surface
* .NET: DevUI: address review and fix dotnet format
- Restore parameterless AddDevUI overloads for binary compatibility on
IServiceCollection and IHostApplicationBuilder.
- Keep /meta outside the auth-filtered group so the frontend can discover
whether a bearer token is required before prompting for one. Surface the
actual requirement via MetaResponse.auth_required.
- Invoke DevUIOptions.ConfigureEndpoints before mapping protected endpoints
so RouteGroupBuilder conventions (RequireAuthorization, rate limiting)
reliably apply.
- Treat a null RemoteIpAddress as non-loopback in DevUIAuthFilter; tests
now set IPAddress.Loopback explicitly when exercising the loopback path.
- Add a DEVUI_AUTH_TOKEN env-var fallback test and a /meta-public test.
- Fix dotnet format: add UTF-8 BOM to new files, simplify a cref in
DevUIOptions, and drop an unused using in the new test.
* .NET: DevUI: add missing authRequired param XML tag
* .NET: DevUI tests: set loopback/AllowRemoteAccess for null-RemoteIp default
DevUIIntegrationTests use the default TestServer which leaves RemoteIpAddress
null. With the new conservative loopback default those tests now hit 403; set
AllowRemoteAccess on the option since those tests are not exercising access
control. Also add the missing SimulateRemoteIp call in the wrong-bearer test.
* .NET: DevUI tests: capture DEVUI_AUTH_TOKEN before parallel tests can see it
The env-var test was leaking DEVUI_AUTH_TOKEN into parallel DevUIIntegrationTests,
intermittently causing their requests to be rejected as 401. Eagerly resolve the
singleton DevUIAuthFilter so its constructor captures the token, then restore the
env var before any HTTP requests run.
* .NET: Remove Foundry Toolbox server-side tools support
Mirrors the Python cleanup in microsoft/agent-framework#5671. Passing
toolbox tools as server-side Responses tools is not the experience we
want to support; the hosted-agent MCP toolbox path (HostedMcpToolboxAITool
+ FoundryToolboxService) remains the supported way to consume Foundry
Toolboxes.
Removed:
- FoundryToolbox static class (GetToolboxVersionAsync / GetToolsAsync /
ToAITools / SanitizeAndConvert)
- AIProjectClient.GetToolboxToolsAsync extension
- Agent_Step25_ToolboxServerSideTools sample (+ slnx entry)
- FoundryToolboxTests, TestDataUtil, HttpHandlerAssert, and the toolbox
JSON fixtures only those tests referenced
- ToolboxHostedAgentTests and ToolboxHostedAgentFixture; the "toolbox"
switch arm + CreateToolboxAgent helper in TestContainer; matching
README scenario row and bootstrap script entry
Kept (MCP path, unchanged):
- HostedMcpToolboxAITool, FoundryAITool.CreateHostedMcpToolbox,
FoundryAIToolExtensions.CreateHostedMcpToolbox(ToolboxRecord/Version)
- FoundryToolboxService, AddFoundryToolboxes, marker injection in
AgentFrameworkResponseHandler, InputConverter.ReadMcpToolboxMarkers
- Hosted-Toolbox sample, McpToolbox* tests, FoundryToolboxServiceTests

* .NET: Add Foundry Toolbox MCP sample (Agent_Step25_FoundryToolboxMcp)
Adds a non-hosted-agent equivalent of the Python foundry_chat_client_with_toolbox.py sample. The agent connects to a Foundry Toolbox's MCP endpoint via Streamable HTTP, injects a fresh Azure AI bearer token on every request, and discovers the toolbox's tools at runtime via McpClient.ListToolsAsync.

* .NET: Persist input messages on streaming errors in PerServiceCallChatHistoryPersistingChatClient
When the underlying chat service emits an in-stream error (for example a
`response.error` SSE event from the OpenAI Responses API on rate limit),
the OpenAI client surfaces it as an `ErrorContent` update and ends the
stream without throwing. Previously, `PerServiceCallChatHistoryPersistingChatClient`
only persisted history when the streaming loop completed successfully and
`NotifyProvidersOfNewMessagesAsync` was called at the end. On the
in-stream-error path, the input messages handed to that iteration -
typically `FunctionResultContent` produced by `FunctionInvokingChatClient`
in the previous iteration - were never persisted. The next run would
replay session history with a dangling `FunctionCallContent` and the
service would reject the request with `No tool output found for function
call <id>`.
This change:
- Adds a `PersistInputOnErrorAsync` helper that persists the input
messages (with no response messages) so function-call/function-result
pairings are not split across failures.
- Calls the helper from every error path: pre-loop enumerator creation,
the first `MoveNextAsync`, the in-loop `MoveNextAsync`, and a new
`finally` that handles abnormal iterator disposal.
- After the streaming loop, scans the assembled response for any
`ErrorContent` and, if present, persists the input, notifies
providers of failure, and throws `InvalidOperationException` so the
error is surfaced to the caller instead of silently corrupting history.
- Hardens `InMemoryChatHistoryProvider.StoreChatHistoryAsync` to treat
a null `RequestMessages` as empty, since the new error path can
invoke it with no response messages.

* Fix dropped FunctionResultContent on streaming pipeline early-disposal
When a consumer of ChatClientAgent.RunStreamingAsync stops iterating early
(e.g. ToolApprovalAgent yields the approval request and then `yield break`),
the framework cascades DisposeAsync down the stream. C# async iterators do
not auto-dispose IAsyncDisposable locals, so the inner enumerator returned
by IChatClient.GetStreamingResponseAsync(...).GetAsyncEnumerator(ct) was
left suspended. That suspended FunctionInvokingChatClient downstream, which
suspended PerServiceCallChatHistoryPersistingChatClient at its `yield
return`, so its finally block never ran and the in-flight
FunctionResultContent for the just-completed tool call was not persisted
to chat history. The next turn then loaded a session that contained a
FunctionCallContent with no matching FunctionResultContent and the model
returned HTTP 400 `No tool output found for function call`.
Fixes:
* ChatClientAgent.RunStreamingAsync: wrap the iteration in
try/finally that disposes the inner enumerator. Disposal now cascades
through the pipeline and PerService's finally runs on early exit.
* PerServiceCallChatHistoryPersistingChatClient: in the streaming path,
snapshot input messages with `messages.ToList()` (the caller, FICC,
reuses a single mutable buffer across iterations and may mutate it
before our finally / error path persists), wrap GetAsyncEnumerator,
the first MoveNextAsync, and in-loop MoveNextAsync in try/catch each
calling PersistInputOnErrorAsync + NotifyProvidersOfFailureAsync, and
add a finally that calls PersistInputOnErrorAsync when the loop did
not exit normally so per-iteration FRCs are persisted on early
disposal as well as on errors.

* .NET: Add tests for PerService streaming error/dispose persistence paths
Adds five regression tests covering the new error-path persistence in
PerServiceCallChatHistoryPersistingChatClient.GetStreamingResponseInnerAsync:
- Persists input messages when GetStreamingResponseAsync throws synchronously.
- Persists input messages when the first MoveNextAsync throws.
- Persists input messages when a mid-stream MoveNextAsync throws.
- Persists input messages when the consumer abandons enumeration early
(the ToolApprovalAgent yield-break / disposal-cascade case).
- Throws and persists input when the stream emits an in-band ErrorContent.
All 66 tests in the class pass on net10.0 and net472.

* .NET: Address PR feedback on PerService streaming error persistence
Two follow-ups from PR #5744 review:
1. Prevent duplicate persistence on the in-loop MoveNextAsync catch path.
The inner catch persists input messages, then rethrows, which propagates
through the surrounding try/finally where loopExitedNormally is still false,
causing the finally to persist again. Introduced an inputPersisted flag
that the inner catch sets after persisting; the finally now skips when
inputPersisted is true.
2. Use the caller's CancellationToken in the abnormal-exit finally instead
of CancellationToken.None, so cleanup remains responsive to cancellation.
Fall back to CancellationToken.None only when the caller's token is
already canceled (otherwise the persist call would observe the
cancellation, throw, and mask the original early-exit reason).
Tightened all five new streaming-error tests from Times.AtLeastOnce to
Times.Once on the input-persistence matcher to regression-guard against
duplicate persistence. All 66 tests in the class still pass (net10.0 + net472).

* .NET: Scope PerService streaming changes to cooperative early-exit only
Per discussion on PR #5744, scope this PR back to fix only the original
ToolApprovalAgent dropped-FunctionResultContent bug and address the
enumerator-disposal review comment. Specifically:
- Remove input-message persistence from the GetAsyncEnumerator and
MoveNextAsync error paths. Routing failed service calls through the
success notification channel was breaking the provider contract; we
will instead rely on inner-agent retries for transient errors. Failure
paths still call NotifyProvidersOfFailureAsync as before.
- Remove the in-stream ErrorContent detection block (same rationale).
- Keep the try/finally that calls the (now narrower) early-exit input
notification on cooperative disposal (e.g. ToolApprovalAgent yield
break). A new serviceErrorOccurred flag ensures we do NOT renotify
on exception paths.
- Always DisposeAsync the underlying enumerator on every exit path,
addressing the copilot-reviewer comment about leaked HTTP/streams.
- Rename PersistInputOnErrorAsync -> NotifyProvidersOfEarlyExitInputAsync
to better reflect what it does and when it runs (rogerbarreto nit).
- Apply rogerbarreto nit on InMemoryChatHistoryProvider null-coalescing.
- Drop the four tests that covered the removed error-path behavior;
keep RunStreamingAsync_PersistsInputMessages_WhenConsumerAbandons
EnumerationAsync (regression guard for the cooperative-pause path).

* .NET: Hosted Agents - RAG Sample with Azure AI Search (#5693)
Adds a Hosted-AzureSearchRag sample plus a live Foundry.Hosting integration
test scenario backed by a real Azure AI Search index.
Sample (Hosted-AzureSearchRag): keyword-only Azure AI Search via
SearchClient adapter into TextSearchProvider, scope-aware
DevTemporaryTokenCredential consuming AZURE_BEARER_TOKEN_FOUNDRY +
AZURE_BEARER_TOKEN_SEARCH for local Docker, Dockerfile + contributor
Dockerfile mirroring Hosted-TextRag.
Integration test: AzureSearchRagHostedAgentFixture extends the PR #5598
HostedAgentFixture with the new azure-search-rag scenario branch in the
shared test container; AzureSearchRagHostedAgentTests asserts the model
returns canary tokens (TR-CANARY-7821, SHIP-CANARY-4493) that exist only
in the seeded documents - real proof the agent grounded its answer in
retrieved content rather than training data.
* Address PR 5701 Copilot review feedback
- Sample README: drop stale 'bootstraps the index on first run' line; index is pre-provisioned out of band
- Sample + TestContainer search adapters: propagate CancellationToken to await foreach via .WithCancellation()
Wesley pointed out (with a clean demo) that AsyncLocal<T> mutations made
inside an awaited async method do not leak back to the caller after the
method returns - the runtime restores the caller's view automatically.
ClientHeadersAgent.RunCoreAsync and RunCoreStreamingAsync are the only
callers of the scope, both are async methods awaited by their callers,
so the explicit using/Dispose pattern was doing work the runtime already
does for us.
* ClientHeadersScope collapsed to a single Current { get; set; } property
over an AsyncLocal<IReadOnlyDictionary<string,string>?>. Drops Push,
the Scope struct, and Dispose. XML doc explains the AsyncLocal natural-
restoration semantics so the design intent is self-documenting.
* ClientHeadersAgent uses a direct ClientHeadersScope.Current = snapshot
before delegating. Drops the local RunAsyncCoreAsync helper and the
snapshot-passed-as-parameter dance.
* Test 10 renamed to ClientHeadersScope_IsAsyncLocalIsolatedAndAutoRestoresAsync;
drops the LIFO claim, keeps the parallel-isolation assertion, and adds
a Wesley-style 'set inside async, caller sees null on return' assertion.
* Test 12 switches from using ClientHeadersScope.Push to direct
Current = ... with try/finally for test isolation.
Snapshot deep-copy in TrySnapshot stays - it defends against caller
mutating the source Dictionary mid-run, which is independent of the
AsyncLocal restoration mechanism.
* .NET: Add Hosted-Files sample + alpha AgentSessionFiles SDK companion + integration test
Closes#5691
- Hosted-Files server sample (mirrors python 06_files): 3 local tools reading
the per-session \C:\Users\rbarreto sandbox volume.
- SessionFilesClient REPL companion: code-first equivalent of
zd ai agent files upload using the alpha
Azure.AI.Projects.AgentSessionFiles SDK (upload/ls/download/rm + session
lifecycle with isolation key).
- session-files scenario added to the Foundry.Hosting.IntegrationTests
multi-scenario harness (PR #5598): SessionFilesHostedAgentFixture +
SessionFilesHostedAgentTests.UploadAndAgentReadsFileAsync, end-to-end
validating upload then agent-reads-file (agent_session_id pinned via
CreateResponseOptions.Patch). Bundled testdata is linked from the sample
so there is a single source of truth.
* .NET: Hosted-Files: REPL companion now demonstrates file-as-knowledge end-to-end
Adds an 'ask <prompt>' command to SessionFilesClient that pins
agent_session_id (via CreateResponseOptions.Patch) so the agent invoked from
the REPL reads files this REPL just uploaded. Surfaces the file content as
agent knowledge in the same in-process loop instead of telling the user to
shell out to azd ai agent invoke.
* .NET: Reshape Hosted-Files sample - bake files into image, SessionFilesClient becomes thin chat REPL
The previous SessionFilesClient leaned on the alpha AgentSessionFiles SDK
to upload files at runtime, which made it diverge from the canonical
Using-Samples shape (SimpleAgent / SimpleInvocationsAgent: tiny chat REPLs).
This change:
- Bakes the sample resources/ directory into the published output via a
Content Include in HostedFiles.csproj. Inside the container the files live
at /app/resources/. Two local function tools (ListFiles, ReadFile) surface
them to the model.
- Reshapes SessionFilesClient as a thin FoundryAgent chat REPL, identical
shape to SimpleAgent. AGENT_ENDPOINT + AGENT_NAME, that is it.
- Demo flow: user asks 'Give me the total revenue in the contoso file' and
the agent answers with the figure read from its bundled file. Validated
end-to-end locally against Hosted-Files on http://localhost:60419.
- Bypasses SampleEnvironment alias on optional env vars to avoid stdin
prompts when running unattended.
The Foundry.Hosting.IntegrationTests session-files scenario continues to
validate the alpha AgentSessionFiles SDK end-to-end (upload + agent reads
from session HOME) and is unchanged.
* .NET: Foundry.Hosting.IntegrationTests TestContainer - constrain session-files tools to $HOME
Addresses the path-traversal review comment on the session-files scenario:
ResolveSessionPath in TestContainer used to allow absolute paths and ..
traversals, which (when chained with indirect prompt injection in an
uploaded file) would let the model read or list arbitrary container files
via the ReadFile / ListFiles tools.
Mirrors the canonicalize + StartsWith(home) pattern from the framework's
own FileSystemAgentFileStore.ResolveSafePath: rejects rooted paths, calls
Path.GetFullPath, and verifies the result stays under $HOME, throwing
ArgumentException otherwise.
The Hosted-Files sample is already safe (uses Path.GetFileName which strips
any directory component) so no change there. The integration test continues
to upload and read 'contoso_q1_2026_report.txt', a single relative filename
which passes the new validation unchanged.
* .NET: SessionFilesHostedAgentTests - shrink to alpha SDK round-trip
The previous test attempted to pin agent_session_id into the /responses
payload via JsonPatch so the agent would read the file uploaded through
AgentSessionFiles. The Foundry alpha service now consistently rejects the
explicit-session-id pin with HTTP 400 conflict on /responses, regardless
of whether the session was pre-created via AgentAdministrationClient or
left to be auto-provisioned, so the agent leg of the test is no longer
reachable from the SDK surface.
Reshape the test to exercise what the alpha SDK actually guarantees:
create session, upload, list (assert presence + size), download (assert
deterministic token), delete (assert removed), cleanup. Everything stays
inside Azure.AI.Projects.Agents.AgentSessionFiles.
Verified live against tao-foundry-prj:
UploadListDownloadAndDeleteAsync passed in 30s.
Full Foundry.Hosting.IntegrationTests run: 25 total, 6 passed, 19
skipped (existing placeholders), 0 failed.
* .NET: SessionFilesHostedAgentTests - rewrite as upload-then-FoundryAgent.RunAsync e2e
Per review feedback the integration test must validate the hosted agent
itself: client uploads a file via the alpha AgentSessionFiles SDK, then
FoundryAgent.RunAsync invokes the deployed agent and the agent's
container-side ReadFile tool surfaces the uploaded file content into the
response.
Test flow:
1. agent.RunAsync(warmup) - platform provisions a per-session container.
2. AgentAdministrationClient.GetSessionsAsync(latest) - resolve the
just-provisioned agent_session_id.
3. AgentSessionFiles.UploadSessionFileAsync - upload contoso file to
that session, asserts BytesWritten + GetSessionFiles listing.
4. agent.RunAsync(real prompt, options=PreviousResponseId chain) -
chained to warmup so the platform routes back to the same container.
5. Assert response contains '1,482.6' (deterministic token from file).
6. Best-effort cleanup.
The test is annotated with [Fact(Skip=...)] right now: the Foundry alpha
service consistently returns HTTP 400 conflict on /responses requests
that link to a prior session via previous_response_id, conversation_id,
or agent_session_id pinning - verified across multiple retries with
multiple chaining strategies. Without that link we cannot route the
second invocation to the same container the file was uploaded to. When
the platform regression is resolved, removing the Skip will exercise
the full flow.
Full Foundry.Hosting.IntegrationTests run with this change: 25 total,
5 passed, 20 skipped (existing placeholders + this one), 0 failed.
* .NET: SessionFilesHostedAgentTests - end-to-end upload-then-FoundryAgent.RunAsync now passes
The blocker was a routing problem combined with a platform race:
1. Routing two /responses calls to the same per-session container.
- agent_session_id pin in body -> 400 (platform treats it as create)
- conversation_id created at project root -> 404 at agent endpoint
- previous_response_id chain -> different session
The working answer is to create the conversation on a per-agent
ProjectOpenAIClient (AgentName option, URL becomes
/agents/{name}/endpoint/protocols/openai/conversations) and pass that
conversation_id on both calls. Both then resolve to the SAME
x-agent-session-id (verified by capturing the response header).
2. Race after AgentSessionFiles upload. The upload mutates session/
conversation revision; a /responses call issued immediately after
400-conflicts with 'modified concurrently. Please retry.' Bounded
exponential retry handles it (5 attempts, 2*attempt seconds).
Test flow:
1. Create per-agent OpenAI client + ProjectConversationsClient + ProjectResponsesClient.
2. CreateProjectConversationAsync on the per-agent client.
3. Warm-up agent.RunAsync(prompt, ChatOptions { ConversationId = ... })
- captures x-agent-session-id from the response header via a custom pipeline policy.
4. AgentSessionFiles.UploadSessionFileAsync to that session id.
5. ProjectResponsesClient.CreateResponseAsync (raw, retry-on-conflict)
with the same conversation_id -> routes back to the same container.
6. Assert response contains '1,482.6' (deterministic token from file).
7. Cleanup: delete file, leave session for TTL.
Verified live against tao-foundry-prj:
UploadedFile_IsReadByHostedAgentAsync passed in 24.9s.
Full Foundry.Hosting.IntegrationTests run: 25 total, 6 passed, 19
skipped (existing placeholders), 0 failed.
* .NET: address Copilot PR review findings
- agent.manifest.yaml: description + tags now reflect bundled-files agent (image-baked /app/resources), not the obsolete session-sandbox tools the prior shape claimed.
- SessionFilesHostedAgentTests: wrap test body in try/finally to call DeleteConversationAsync on the conversation we created (matches HappyPathHostedAgentTests pattern; prevents conversation leakage across runs).
- ResponseHeaderCapturePolicy: drop unused LastRequestBody capture left over from diagnosis.
Test still passes live (40s).
* .NET: Hosted-Files: split into bundled vs session-file tool pairs
The previous Hosted-Files agent only exposed bundled (image-baked) file
knowledge. The platform also surfaces session-uploaded files at \C:\Users\rbarreto
inside the per-session container per container-image-spec.md line 172
(verified live by SessionFilesHostedAgentTests). The sample now teaches
both patterns.
Two distinct tool pairs, each scoped to its own root:
Bundled (image-baked): ListBundledFiles, ReadBundledFile
-> /app/resources/ (BUNDLED_FILES_DIR override)
Session-uploaded (\C:\Users\rbarreto): ListSessionFiles, ReadSessionFile
-> \C:\Users\rbarreto (default /home/session per container spec)
Security model -- distinct tools, distinct sandboxes:
- Tool input is a fileName, not a path. Schema-level: model cannot
request directories or traversals.
- Path.GetFileName(input) strips any directory components.
- Path.GetFullPath + StartsWith(root) check rejects anything outside
the tool's root, mirroring FileSystemAgentFileStore.ResolveSafePath.
- Read-only, non-recursive listing. No glob, no '..'.
- Failures non-revealing: 'File <name> not found in <scope>.'
The two roots are physically isolated (image-baked vs platform-mounted
per-session volume). A bundled-root tool can never reach a session file
and vice-versa, even if the implementation has a bug.
README updated to document both flows, the security pattern, and cite
the container-image-spec.md line 172 contract for \C:\Users\rbarreto. Live IT
SessionFilesHostedAgentTests.UploadedFile_IsReadByHostedAgentAsync
re-passed in 42s after the change (TestContainer is unchanged; the
sample-agent split does not affect the IT).
* .NET: Hosted-Files README - fix broken relative link to IT (4..5 dots)
* .NET: Foundry.Hosted IT - fix MSBuild parallel-output races
Two surgical changes inside the dotnet-foundry-hosted-it job:
1. Replace dotnet build <slnx> -f net10.0 with dotnet build <test.csproj>. The test csproj pins TargetFrameworks=net10.0 and its ProjectReference closure gives MSBuild a single-rooted graph, eliminating the duplicate inner-builds that race on bin/obj. Drops the two New-FilteredSolution.ps1 steps.
2. In it-build-image.ps1, drop the -UsePrebuiltProjectReferences switch and always pass --no-dependencies to dotnet publish. Publish now resolves TestContainer's framework refs by reading prebuilt DLLs and never re-touches them. Replaces the partial-mitigation in PR #5689 with a structural fix.
Local validation confirmed published Foundry.dll has identical mtime and bytes as the prebuild output.
* .NET: dotnet test - use --project flag for Microsoft Testing Platform
* Adding the ability to inject messages during the function call loop
* Split message injection functionality
* Remove interface, since it is not required not that we split the chat client.
* Address conversation id propogation
* Fix formatting issue
* .NET: Foundry agent-endpoint constructor uses ProjectOpenAIClient directly to fix hosted-agent URL routing
Fixes the experimental FoundryAgent(Uri agentEndpoint, AuthenticationTokenProvider, ...)
constructor so it actually works against Foundry hosted agents.
The previous implementation routed through AzureAIProjectChatClient, which
internally called aiProjectClient.GetProjectOpenAIClient().GetProjectResponsesClientForAgent(...).
For an agent-endpoint URL of the canonical shape
https://<host>/api/projects/<project>/agents/<agentName>/endpoint/protocols/openai
the chain produced
POST https://<host>/api/projects/<project>/openai/v1/responses
(project-level path, no /agents/ segment). The Foundry service rejects this with
HTTP 400 "Hosted agents can only be called through the agent endpoint:
.../agents/<agentName>/endpoint/protocols/openai/responses".
The constructor also extracted the agent name via
agentEndpoint.Segments[^1].TrimEnd('/'), which returns "openai" (the last segment),
not the agent name.
What changed
- Public ctor signature: clientOptions parameter type changed from
AIProjectClientOptions? to ProjectOpenAIClientOptions?. The constructor is
fundamentally building a ProjectOpenAIClient; accepting AIProjectClientOptions
was a leaky abstraction whose translation silently dropped any pipeline
policies the caller added via AddPolicy(...). With the direct type, caller
policies pass through to the per-agent traffic verbatim.
- Per-agent client construction: `new ProjectOpenAIClient(BearerTokenPolicy, ProjectOpenAIClientOptions)`
with Endpoint and AgentName set, then `GetProjectResponsesClient().AsIChatClient()`.
The SDK auto-appends ?api-version=v1 when AgentName is set.
- New private static ParseAgentEndpoint helper: single source of truth for both
agent-name extraction and project-root derivation. Tolerates trailing slash,
case variants on /agents/ and the suffix segment, strips query/fragment, and
throws ArgumentException with paramName=nameof(agentEndpoint) for malformed input.
- Project-level client (used by CreateConversationSessionAsync) is built fresh
from the derived project root with primitive properties copied
(RetryPolicy/NetworkTimeout/Transport/UserAgentApplicationId) plus MEAI UA.
- New GetService<ProjectOpenAIClient>() entry alongside the existing
GetService<AIProjectClient>() (the latter returns null in agent-endpoint mode
since no AIProjectClient is constructed on that path).
- Endpoint and AgentName on caller-supplied ProjectOpenAIClientOptions are
overridden by values derived from agentEndpoint.
Compatibility
- FoundryAgent is [Experimental(OPENAI001)]. No GA surface touched. The Foundry
project does not maintain PublicAPI.*.txt baselines so there is no shipped
baseline to update.
- The Microsoft.Agents.AI.Foundry csproj pins
Azure.AI.Projects to VersionOverride 2.1.0-beta.1 (matching what the IT and
hosting projects already use); the central pin in Directory.Packages.props
stays at 2.0.0.
- WireClientHeaders from PR #5652 is invoked on the agent-endpoint path so
per-call x-client-* headers behave identically across both ctors.
Tests
- 23 new unit tests in FoundryAgentTests.cs:
- 12 for the agent-endpoint constructor (URL routing for non-streaming and
streaming, conversations URL shape, MEAI UA stamping, caller-policy
passthrough on the per-agent pipeline, Endpoint/AgentName override
semantics, GetService matrix, ProjectOpenAIClient propagation,
UserAgentApplicationId propagation, null-arg validation, ID/Name slug)
- 9 for ParseAgentEndpoint (standard shape, trailing slash, casing,
sovereign-cloud host without /api/projects/ literal prefix, special chars
in agent name, query/fragment stripping, three negative cases)
- 2 null-arg tests for the public ctor
- All 250 Microsoft.Agents.AI.Foundry.UnitTests pass (was 221 baseline plus
29 from PR #5652 plus 23 new in this PR equals 273; pre-existing tests
collapsed by the rebase merge keep the total at 250).
- All 225 Microsoft.Agents.AI.Foundry.Hosting.UnitTests pass; no behavioral
change to the hosting layer.
- dotnet build clean across net8/9/10/netstandard2.0/net472 with
TreatWarningsAsErrors=true.
- dotnet format --verify-no-changes clean for the touched src and test projects.
* .NET: Bump central Azure.AI.Projects pin to 2.1.0-beta.1 and flip Microsoft.Agents.AI.Foundry to preview
Required to fix the NU1109 downgrade chain that broke CI on the agent-endpoint
constructor rewire (#5677). Microsoft.Agents.AI.Foundry now depends on
ProjectOpenAIClientOptions.AgentName and the (AuthenticationPolicy, options)
constructor that only exist in Azure.AI.Projects 2.1.0-beta.1.
Changes:
* Directory.Packages.props: Azure.AI.Projects 2.0.0 -> 2.1.0-beta.1.
* Microsoft.Agents.AI.Foundry.csproj: drop IsReleased=true so the package ships
as preview (matches the beta SDK we now depend on). Add a comment noting the
flip is temporary and should revert once Azure.AI.Projects ships a stable
2.1.0.
* Drop redundant VersionOverride="2.1.0-beta.1" from the 10 csprojs that had it
as a workaround; the central pin now suffices.
Verified:
* dotnet build agent-framework-dotnet.slnx --warnaserror clean across all TFMs.

# Hosted session identity context for Foundry Hosting
## Context and Problem Statement
Server-hosted Foundry agents need a way to scope per-user state (most notably `FoundryMemoryProvider` memories) by the end user that initiated the request. The Foundry platform already injects `x-agent-user-isolation-key` and `x-agent-chat-isolation-key` headers on every Responses request, but the agent-framework hosting layer did not surface those values to `AIContextProvider` instances. The provider's `stateInitializer` only received an `AgentSession?` with no identity attached, so per-user scoping was impossible without out-of-band plumbing.
## Decision Drivers
- Memory and any future user-private context must be partitioned per end user without per-sample boilerplate.
- The identity must be **read-only** from the perspective of `AIContextProvider`s, so a buggy or hostile provider cannot escalate or leak across users.
- The persisted session must validate against the live request on every resume to defend against session-id leak and in-process tampering.
- The change must work for every existing hosted-agent type (`ChatClientAgent`, `FoundryAgent`, future ones) without per-type refactoring of cast-heavy code paths in `Microsoft.Agents.AI`.
- Local Docker debugging must remain possible when the platform headers are absent.
## Considered Options
1.**`HostedSessionContext` stored in `AgentSessionStateBag`, exposed via a public read accessor and an `internal` setter.** Hosting writes once on session creation and validates on every resume.
2.**Specialised `HostedAgentSession : AgentSession` wrapper** that carries `UserId`/`ChatId` properties, with `GetService<ChatClientAgentSession>()` as the unwrap escape hatch.
3.**New property on `AgentSession` base class** (`HostedSessionContext? HostedContext { get; internal set; }`).
4.**AsyncLocal middleware** that reads the headers and stuffs them into a per-request `AsyncLocal<HostedSessionContext>` consumed by the provider.
For the source of identity:
- A. The platform-injected `IsolationContext` exposed by `ResponseContext.Isolation` (typed `UserIsolationKey`/`ChatIsolationKey`).
- B. The OpenAI Responses spec's top-level `request.User` field.
- C. A custom HTTP header `x-client-user`.
## Decision Outcome
**Option 1** was chosen for the storage shape, sourced from **Option A** (`ResponseContext.Isolation`).
Rationale:
- **Wrapper rejected (Option 2).** `ChatClientAgentSession` is `sealed` and `ChatClientAgent` rejects any other session type via direct `is not ChatClientAgentSession` checks at multiple call sites. Wrapping would force non-trivial refactors across `Microsoft.Agents.AI` and a corresponding repeat for every other agent type.
- **Base-class property rejected (Option 3).** Leaks "hosted" semantics into the universal `AgentSession` abstraction used by Durable, A2A, and CopilotStudio agents that have no notion of a hosted user.
- **AsyncLocal rejected (Option 4).** Surfaces the concept only locally, requires every consumer to re-implement the bridge, and cannot be enforced as read-only.
- **`request.User` rejected (Option B).** Set by the caller, not the platform. Forging it client-side trivially defeats per-user partitioning.
- **`x-client-user` rejected (Option C).** Non-standard, requires custom HTTP plumbing, and duplicates the platform-provided isolation contract.
Implementation summary in `Microsoft.Agents.AI.Foundry.Hosting`:
| Type | Visibility | Purpose |
|---|---|---|
| `HostedSessionContext` | public sealed | Captures `UserId` and `ChatId` (both required, non-whitespace). |
| `HostedSessionContextExtensions.GetHostedContext` | public | Read accessor for `AIContextProvider`s. |
| `HostedSessionContextExtensions.SetHostedContext` | internal | Writer reserved for the hosting assembly. Backed by `AgentSessionStateBag` under a well-known key for serialisation. |
| `PlatformHostedSessionIsolationKeyProvider` | internal sealed | Default implementation. Maps `context.Isolation.UserIsolationKey` and `context.Isolation.ChatIsolationKey`. Returns `null` when either is absent. |
Behaviour added to `AgentFrameworkResponseHandler.CreateAsync`:
1. Resolve `HostedSessionIsolationKeyProvider` from DI; fall back to `PlatformHostedSessionIsolationKeyProvider`.
2. Call `GetKeysAsync(context, request, cancellationToken)`. A `null` result throws `InvalidOperationException` (becomes 500). A null/whitespace `UserId` or `ChatId` is rejected by `HostedSessionContext`'s constructor.
3. Branch on the **session's existing context**, not on whether a `conversation_id` was supplied:
- **No session (`session is null`):** nothing to stamp; skip.
- **Session present but un-stamped (`GetHostedContext() is null`):** treat as fresh. This covers both newly-created sessions and pre-existing sessions whose `conversation_id` was provisioned externally (e.g. via `conversations.CreateProjectConversationAsync()`) before the first hosted-agent request. Stamp the resolved identity now.
- **Session present with stamped context:** strict resume. The persisted `UserId` and `ChatId` must equal the resolved values exactly. Mismatch throws `ResponsesApiException` with status 403 and body `Hosted session identity context mismatch`.
## Consequences
Positive:
- Per-user memory partitioning works out of the box for any agent that consumes a `Microsoft.Agents.AI.Foundry.FoundryMemoryProvider` configured to read `session.GetHostedContext().UserId`.
- Cross-user session-id leak and in-process tampering of the persisted identity both surface as a 403 with a deliberately uninformative body.
- The identity is opaque to the framework, matching the platform's semantics. The framework never inspects user identity; the `IsolationContext` keys are pre-partitioned per agent.
Negative:
- Every existing hosted sample fails locally without a `HostedSessionIsolationKeyProvider` registered, because the platform headers are absent outside the platform. Mitigated by shipping `Hosted_Shared_Contributor_Setup` with `DevTemporaryLocalSessionIsolationKeyProvider` and `AddDevTemporaryLocalContributorSetup`, and migrating all 9 existing responses samples.
- An attacker who can plant an un-stamped session under a victim's `conversation_id`*before* the victim's first hosted-agent request would be stamped with the attacker's identity on that first request. This is not a regression vs. behaviour without this contract, and is mitigated in practice because the `conversation_id` namespace is allocated by the platform per project. Once a session is stamped, the strict equality check fully defends the resume path.
## Out of scope
- Per-request `User` field on `CreateResponse` is intentionally not consumed; only the platform `IsolationContext` headers carry trustworthy identity.
- Generic (non-Foundry) hosting layers can re-define an equivalent type if needed; nothing in this ADR is moved into `Microsoft.Agents.AI.Hosting` because `Microsoft.Agents.AI.Foundry.Hosting` does not depend on it.
- HMAC tamper signatures over the persisted context are not implemented; comparison against `ResponseContext.Isolation` on every request is sufficient because the platform sets those headers at the trust boundary.

This sample shows how to use a Foundry Toolbox by pointing an `McpClient` at the toolbox's MCP endpoint. The agent discovers the toolbox's tools at runtime and invokes them locally over MCP.
## What this sample demonstrates
- Connecting to a Foundry toolbox's MCP endpoint via Streamable HTTP transport
- Injecting a fresh Azure AI bearer token (`https://ai.azure.com/.default`) on every MCP request
- Passing the discovered MCP tools to `AIProjectClient.AsAIAgent(...)`
- Optional helper to create (or replace) a sample toolbox in the project so the sample is runnable end-to-end
## Prerequisites
- A Microsoft Foundry project with a toolbox configured (or let the sample create one for you)
- Azure CLI installed and authenticated (`az login`)
