Added CosmosOptionsHelper (in Microsoft.Agents.AI.CosmosNoSql namespace)
that sets CosmosClientOptions.ApplicationName per component, producing
wire-visible UserAgent suffixes:
- CosmosChatHistoryProvider: Microsoft.Agents.CosmosNoSql.ChatHistory/{version}
- CosmosCheckpointStore: Microsoft.Agents.CosmosNoSql.Checkpoint/{version}
This ensures Cosmos DB requests from the Agent Framework are identifiable
in telemetry, enabling usage tracking and diagnostics queries that can
distinguish between chat history and checkpoint workloads.
Addressed review feedback:
- Truncates ApplicationName to 64 chars (Cosmos SDK max length)
- Moved helper to Microsoft.Agents.AI.CosmosNoSql namespace (scoped ownership)
- Uses StringComparison.Ordinal for IndexOf call
When users provide their own CosmosClient instance, the ApplicationName
is not overridden - users retain full control.

* Fix CopySessionConfig and CopyResumeSessionConfig ignoring Streaming value (#4732)
CopySessionConfig() and CopyResumeSessionConfig() hardcoded Streaming = true,
ignoring the caller's explicitly set SessionConfig.Streaming value. This made it
impossible to disable streaming when using AsAIAgent() with the GitHub Copilot SDK.
Changed both methods to use source.Streaming ?? true (and source?.Streaming ?? true
for the nullable overload), preserving the caller's value when set while maintaining
backward compatibility by defaulting to true when unset.

* Fix non-streaming response path for SessionConfig.Streaming=false (#4732)
The config-copy fix (preserving Streaming=false via null-coalescing) was
already in place, but ConvertToAgentResponseUpdate(AssistantMessageEvent)
always emitted raw AIContent without text—assuming delta events had already
delivered it. When streaming is disabled there are no delta events, so the
assistant's final text was silently dropped.
Changes:
- Add isStreaming parameter to ConvertToAgentResponseUpdate for
AssistantMessageEvent so it emits TextContent in non-streaming mode.
- Capture the resolved streaming flag in RunCoreStreamingAsync and pass
it through the event subscription closure.
- Add/update unit tests for both streaming and non-streaming paths.

* Add test for null Data path in ConvertToAgentResponseUpdate (#4732)
Add a regression test covering the null-propagation path where
AssistantMessageEvent.Data is null. The production code already handles
this via ?. operators, but no test previously verified the behavior.

* .NET: Make GitHub.Copilot.SDK build targets reach transitive consumers (#6455)
Microsoft.Agents.AI.GitHub.Copilot now ships a buildTransitive/ bridge so
consumers who only reference this package (the normal use case) get the
GitHub.Copilot.SDK's CLI binary-download MSBuild targets executed at build
time. Without this, the SDK shipped its targets under build/ which NuGet
only auto-imports for projects with a direct PackageReference to the SDK,
so consumers of the adapter package got only the managed .dll, no
copilot.exe in their output, and a runtime InvalidOperationException on
the first RunAsync.
The bridge consists of two files under buildTransitive/:
* Microsoft.Agents.AI.GitHub.Copilot.props is generated at this package's
pack time and pins the SDK version (from PackageVersion items in
Directory.Packages.props) into _MicrosoftAgentsAICopilotSdkVersion.
* Microsoft.Agents.AI.GitHub.Copilot.targets is static and imports the
SDK's own build/GitHub.Copilot.SDK.targets from the NuGet cache using
the pinned version. The version-pin condition no-ops gracefully if the
resolved SDK differs from what was baked in (e.g. consumer overrides
the SDK version directly), so this is purely additive.
Verified by packing locally, restoring from a flat local feed, and
building a transitive-only consumer (PackageReference to MAF only, no
direct SDK ref). copilot.exe lands at bin/{cfg}/{tfm}/runtimes/{rid}/
native/copilot.exe as expected, matching the path the SDK's runtime
CopilotClient looks at.
Fixes#6455
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* Address Copilot review feedback (#6457)
- buildTransitive/.targets: compute the full SDK targets path with a single
Path.Combine call into one property (_MicrosoftAgentsAICopilotSdkTargetsPath),
used in both Project= and Exists() — no more split between Path.Combine for
the directory and inline / separator for the file name.
- Split the version-defaulting Condition between the two files: the generated
.props now just bakes the packaged SDK version into a dedicated property
(_MicrosoftAgentsAICopilotSdkPackagedVersion), and the static .targets file
is the single place that defaults _MicrosoftAgentsAICopilotSdkVersion to it.
Removes the need for any MSBuild escape gymnastics in the pack-time string
construction, and keeps the consumer override path the same.
- _GenerateBuildTransitiveProps now hangs off public BeforeTargets (Build, Pack)
in addition to _GetPackageFiles, so the file is generated even without a
full pack, and we're not solely dependent on an underscore-prefixed internal
target. The <None Pack=true /> items live in a top-level ItemGroup so they
are collected at evaluation time instead of being added from inside the
Target.
End-to-end retested with a transitive-only consumer (PackageReference to MAF
only, no direct GitHub.Copilot.SDK ref): copilot.exe lands at
bin/Debug/net10.0/runtimes/win-x64/native/copilot.exe (141.8 MB) as before.

* .NET: Add Hosted-Toolbox-AuthPaths sample and auto-map /readiness with toolbox health gating (#5777)
Add a new hosted agent sample demonstrating five MCP tool authentication paths
(API key, agent MI, project MI, custom OAuth, literal token) via a Foundry Toolbox.
Package changes (Microsoft.Agents.AI.Foundry.Hosting):
- MapFoundryResponses now auto-maps GET /readiness via MapHealthChecks, idempotent
across Tier 1/2 (AgentHost, already mapped) and Tier 3 (WebApplication, gap filled).
- AddFoundryResponses registers AddHealthChecks() so the pipeline is available.
- AddFoundryToolboxes registers FoundryToolboxHealthCheck on the /readiness aggregate,
gating readiness on pre-registered toolbox startup outcome (per spec section 3.1).
- FoundryToolboxService now exposes StartupStatus and FailedToolboxNames properties.
New types:
- FoundryToolboxStartupStatus (public enum): Pending, Healthy, Failed, NoEndpoint.
- FoundryToolboxHealthCheck (internal IHealthCheck): adapts startup status to the
AspNetCore HealthChecks pipeline with failed toolbox names in result data.
Tests:
- 3 new tests for /readiness auto-mapping (Tier 3 default, pre-mapped skip, idempotent).
- 4 new tests for FoundryToolboxHealthCheck (Pending, NoEndpoint, Failed, Healthy).
- 3 enhanced FoundryToolboxServiceTests with StartupStatus assertions.
* .NET: Align FoundryToolboxService with tools-integration-spec (#5777 Part A)
Bring Microsoft.Agents.AI.Foundry.Hosting's toolbox path into compliance with
tools-integration-spec.md sections 2-4, 6.3, and 9. Empirically validated
against tao-foundry-prj: the previous code (reading FOUNDRY_AGENT_TOOLSET_ENDPOINT,
which the platform never injects) silently registered zero tools in production.
Package changes (Microsoft.Agents.AI.Foundry.Hosting):
- FoundryToolboxService.StartAsync now derives the toolbox proxy base URL from
the platform-injected FOUNDRY_PROJECT_ENDPOINT and constructs the per-toolbox
URL as {FOUNDRY_PROJECT_ENDPOINT}/toolboxes/{name}/mcp?api-version={ApiVersion}
per spec sections 2-3. The legacy FOUNDRY_AGENT_TOOLSET_ENDPOINT env var is
removed outright (preview package, no production consumers).
- FoundryToolboxOptions.ApiVersion default flipped to 'v1' to match spec example.
- FoundryToolboxBearerTokenHandler always sends the mandatory
Foundry-Features: Toolboxes=V1Preview header per spec section 2, merging any
additional flags supplied via the FOUNDRY_AGENT_TOOLSET_FEATURES env var.
- FoundryToolboxBearerTokenHandler token scope changed from
https://cognitiveservices.azure.com/.default to https://ai.azure.com/.default
per spec section 4.
- FoundryToolboxBearerTokenHandler propagates W3C trace context (traceparent,
tracestate, baggage) from Activity.Current per spec section 6.3.
Sample changes:
- Hosted-Toolbox-AuthPaths and Hosted-Toolbox Program.cs, README.md, and
.env.example corrected to describe the actual env-var contract
(FOUNDRY_PROJECT_ENDPOINT auto-injected; AZURE_AI_PROJECT_ENDPOINT as the
local-dev fallback). Removes the misleading 'auto-injected by Foundry runtime'
claims for FOUNDRY_AGENT_TOOLSET_ENDPOINT.
- Hosted-Toolbox-AuthPaths/agent.manifest.yaml declares the toolbox and model
dependencies under resources[] per the AgentManifest schema so azd ai agent
init users get them provisioned automatically.
Tests:
- 4 new FoundryToolboxServiceTests covering env-var derivation, EndpointOverride
precedence, trailing-slash normalization, and the existing NoEndpoint behavior
under the new env var name.
- 4 new FoundryToolboxBearerTokenHandlerTests covering token scope, mandatory
feature header always present, header merging with override, no duplicate
mandatory flag, trace context propagation from Activity.Current, and no
override of caller-set traceparent.
- New FoundryProjectEndpointEnvFixture xUnit collection definition serializes
env-var-mutating tests across FoundryToolboxServiceTests and
FoundryToolboxHealthCheckTests, preventing parallel-execution races.
- FoundryToolboxHealthCheckTests adjusted for the new env var name.
* .NET: Drop ACA prereq from Hosted-Toolbox-AuthPaths README (#5777 Part B)
Empirically verified that any Azure Cognitive Services MCP endpoint already in
the Foundry project (e.g., a Language service MCP) accepts Entra tokens and can
serve Paths 2 and 3 without deploying a separate Azure MCP Server to ACA.
README updates:
- Step 0 rewritten: 'Identify an Entra-authenticated MCP target in your project'
instead of 'Deploy Azure MCP Server to Azure Container Apps' (the original
azmcp-foundry-aca-mi setup is now optional, not required).
- Auth-paths matrix updated to describe AAD-based connections targeting a
Cognitive Services MCP URL (e.g., Language service) instead of an ACA URL.
- Step 2 connections table updated: the Entra ID category is now a single 'AAD'
authType. The original 'Agent Identity' vs 'Project Managed Identity' as
selectable connection sub-types is NOT exposed via the ARM control plane
today; the platform selects the calling principal contextually. Both
connections in the walkthrough share the same shape and target.
- Added an explicit RBAC note: the agent identity AND project MI must hold the
required role (typically Cognitive Services User) on the target resource;
without it the MCP server returns HTTP 401 even though the connection wiring
is correct.
- Toolbox tool entries renamed lang_entra_agent / lang_entra_project to
match the new connection names.
Empirical validation supporting these changes is captured in the session
plan.md (Part B addendum).
* .NET: Document correct connection shape for Hosted-Toolbox-AuthPaths Paths 2/3 (#5777)
Updates the sample README with the verified connection shape and RBAC procedure
for Microsoft Entra agent-identity and project-managed-identity MCP authentication:
- Connection authType values: AgenticIdentityToken (agent identity) and
ProjectManagedIdentity (project MI), both with category=RemoteTool.
- Top-level audience property required; for Cognitive Services targets the value
is https://cognitiveservices.azure.com.
- Connections created via ARM REST (the Foundry portal wizard does not yet
expose these authTypes).
- RBAC grants target the project's shared agent identity blueprint principal
(project.properties.agentIdentity.agentIdentityId) for Path 2 and the
project's system-assigned MI (project.identity.principalId) for Path 3.
- Troubleshooting table updated with the audience-mismatch symptom and the
startup-cache behavior of FoundryToolboxService.
* .NET: Drop Path 3 (project MI) and align with new agent model in Hosted-Toolbox-AuthPaths (#5777)
Updates the sample to use only the new Foundry agent object model and removes
the project managed identity path:
- Auth-path matrix reduced to four paths: key, Entra agent identity, custom
OAuth, inline authorization. Project managed identity is moved into a note
describing when it applies (multiple agents sharing access) rather than as
a documented sample path.
- RBAC instructions reference the agent's own instance_identity.principal_id
from the agent ARM resource (new agent object model) instead of the
project's shared agent identity blueprint (legacy model).
- Step 2 (connections) creates only the AgenticIdentityToken connection.
- Step 3 (toolbox tools) lists four tool entries instead of five.
- Sample prompts and troubleshooting table updated to match.
* .NET: Restore Path 3 (project MI) to Hosted-Toolbox-AuthPaths matrix (#5777)
The sample's purpose is to enumerate every authentication path a Foundry toolbox
can drive, not to pick one. Path 3 belongs alongside the other four with
explicit guidance for when each path is the right choice.
- Path 3 (project managed identity, authType=ProjectManagedIdentity) restored
to the matrix with a 'When to pick this' column.
- Step 2 (connections) provisions both lang-mcp-agent-id and lang-mcp-project-mi
via ARM REST.
- Step 3 (toolbox) lists five tool entries (one per path).
- RBAC instructions cover both the agent's instance identity (Path 2) and the
project's system-assigned MI (Path 3).
- Sample prompts include all five paths.
- Troubleshooting table updated accordingly.
* .NET: Fix duplicate line in Hosted-Toolbox-AuthPaths README (#5777)
* .NET: Fix broken markdown link to ToolCallingApprovalHostedAgentFixture (#5777)
* .NET: Fix relative path depth in markdown link (#5777)
* .NET: Address Copilot review feedback for #5777
- FoundryToolboxHealthCheck description: rename FOUNDRY_AGENT_TOOLSET_ENDPOINT
→ FOUNDRY_PROJECT_ENDPOINT (stale reference; operator-facing in /readiness body).
- FoundryToolboxStartupStatus.NoEndpoint XML doc: same rename.
- ServiceCollectionExtensions XML docs: same rename + URL shape update.
- Foundry.Hosting.IntegrationTests.TestContainer: remove explicit
app.MapGet('/readiness') — now redundant + would conflict with the
auto-mapped readiness route from MapFoundryResponses.
- Hosted-Toolbox-AuthPaths agent.manifest.yaml: parameterize TOOLBOX_NAME via
{{TOOLBOX_NAME}} template substitution and declare it under parameters with a
default of 'auth-paths-toolbox' so the README's 'use any name' guidance
actually works for hosted deployments.
* .NET: Address Copilot review round 2 — fallback env + dedup + naming (#5777)
- FoundryToolboxService.StartAsync: fall back to AZURE_AI_PROJECT_ENDPOINT when
FOUNDRY_PROJECT_ENDPOINT is absent. Matches the local-dev convention used by
the samples and resolves the doc/code mismatch flagged in review.
- FoundryToolboxHealthCheck description updated for the fallback.
- AddFoundryToolboxes: guard against duplicate health-check registration via an
explicit name-uniqueness check on HealthCheckServiceOptions.Registrations.
AddCheck<T>(name, ...) does not dedupe by name, so repeated AddFoundryToolboxes
calls would have registered multiple instances.
- FoundryToolboxOptions.EndpointOverride doc: clarify URL becomes
{EndpointOverride}/toolboxes/{name}/mcp (was missing /toolboxes/ segment).
- Hosted-Toolbox sample (Program.cs + README): switch FOUNDRY_TOOLBOX_NAME to
TOOLBOX_NAME (the FOUNDRY_* prefix is reserved by the platform), default
changed from 'my-toolset' to 'my-toolbox', terminology updated from 'Toolset'
to 'Toolbox'.
- FoundryToolboxServiceTests: 2 test renames to reflect what they actually
assert (StartupStatus + FailedToolboxNames, not URL shape directly).
- Tests adjusted to clear both env vars in NoEndpoint scenarios.
* .NET: Fix stale NoEndpoint XML doc and misleading test comment (#5777)
Update FoundryToolboxStartupStatus.NoEndpoint XML doc to mention both
FOUNDRY_PROJECT_ENDPOINT and AZURE_AI_PROJECT_ENDPOINT (the service
checks both since the fallback was added).
Fix test comment that claimed URL derivation validation when the test
only asserts on StartupStatus and FailedToolboxNames.
* Remove OAuth consent path from AuthPaths sample, keep four working auth paths
The interactive OAuth identity passthrough path needs a protocol gap closed in the
hosting package (the proprietary oauth_consent_request item is not representable
through the OpenAI/MEAI abstractions), so it is deferred to a separate spike branch.
This strips the OAuth path from the AuthPaths sample, the companion REPL client, the
agent manifest, and the docs, then renumbers the inline Authorization path so the
sample teaches four contiguous paths: API key via connection, Entra agent identity,
Entra project managed identity, and inline Authorization (anti-pattern).
Package code is unchanged; the consent infrastructure already present in main stays
as baseline. Both samples build with --warnaserror and all 246 hosting unit tests pass.
* .NET: Drop project MI auth path and dedicated client from Hosted-Toolbox-AuthPaths (#5777)
Live validation against tao-foundry-prj showed the ProjectManagedIdentity
path failing with an unresolved token audience 401, so the sample now ships
three working auth paths instead of four: connection key, agent managed
identity, and inline Authorization.
Changes:
- Remove the project managed identity path from the AuthPaths sample matrix,
prerequisites, connections, toolbox table, prompts, Program.cs instructions
and agent.manifest.yaml.
- Delete the near duplicate Hosted-Toolbox-AuthPaths-Client project and remove
it from the solution. The README now drives the agent with the shared
SimpleAgent REPL via AsAIAgent(agentEndpoint).
- Correct the troubleshooting note: the Foundry toolbox tools/list is all or
nothing, so one bad source returns -32007, fails startup, and returns 424
for every path. Add the allowed_tools caveat that names must match the
upstream server.
- Mark the toolbox startup status and health check experimental under
AgentsAIExperiments (MAAI001) instead of AIOpenAIResponses, and update the
package NoWarn set accordingly.
* .NET: Address PR review nits for Hosted-Toolbox-AuthPaths (#5777)
- Remove duplicated NU1903 comment in Foundry.Hosting csproj.
- Fix stale 'four-tool' cross-links in Hosted-Toolbox and Hosted-McpTools READMEs to describe the three-path toolbox driven by the shared SimpleAgent REPL.
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* .NET: Address toolbox startup-status review feedback (#5777)
- Rename FoundryToolboxStartupStatus.Failed to Unhealthy so it is the proper opposite of Healthy, and clarify the doc comment covers the partial-failure case.
- Raise the missing-endpoint toolbox log from Information to Warning, since enabling toolboxes is an explicit opt-in and a silently disabled toolbox warrants a higher-severity signal.
- Update unit tests and the AuthPaths README troubleshooting row accordingly.

* Fix Magentic to share agent replies across team
The per-round instruction was sent untargeted (fan-out delivered it to
every participant) and replies were never relayed, so a later speaker saw
the prior speaker's instruction but not its response - inverted from
GroupChatHost and the Python reference.
- Target the instruction at the selected speaker only.
- Broadcast each reply to the other participants (buffered, no TurnToken),
excluding the responder via _currentSpeakerExecutorId, mirroring
GroupChatHost.
- Persist _currentSpeakerExecutorId across checkpoints.
- Add a regression test.
* Address review feedback: null-guard, explicit checkpoint key, drop vacuous assertion
* Address review feedback: centralize checkpoint keys, clear current speaker
- Move CurrentSpeakerStateKey into MagenticConstants as
nameof(CurrentSpeakerStateKey)
- Clear _currentSpeakerExecutorId in ResetAndReplanAsync and
PrepareFinalAnswerAsync so a checkpoint taken in those windows does not
persist a stale speaker
- Add UTF-8 BOM to RecordingEchoAgent.cs to satisfy the format check.
* Move token params from HarnessAgent constructor to options
Remove the required maxContextWindowTokens and maxOutputTokens
constructor parameters from HarnessAgent and AsHarnessAgent, replacing
them with optional MaxContextWindowTokens and MaxOutputTokens properties
on HarnessAgentOptions.
When both values are provided, compaction is enabled as before (in-loop
CompactionProvider and chat reducer on the default InMemoryChatHistory
Provider). When either is null, compaction is disabled entirely, making
it opt-in.
New constructor: HarnessAgent(IChatClient, HarnessAgentOptions?,

* Promote Workflows.Declarative packages to stable versions
* Address PR feedback: enable package validation on GA declarative packages
Both Workflows.Declarative and Workflows.Declarative.Mcp set IsReleased=true
but were disabling package validation, bypassing the repo's GA convention
(see dotnet/nuget/nuget-package.props which auto-enables validation when
IsReleased=true).
Re-enable validation by removing the local EnablePackageValidation=false
overrides and pointing PackageValidationBaselineVersion at 1.8.0-rc1 (the
latest published version of each package). This catches accidental breaking
changes between RC and the first GA. Future GAs should bump the baseline to
the previous GA version.
Verified locally: dotnet build -c Release on both projects runs
RunPackageValidation -> APICompat ran successfully without finding any
breaking changes.

* Fix missing id on function_call_output in Foundry Hosting
The Foundry storage layer was rejecting responses with
"ID cannot be null or empty (Parameter 'id')" because
function_call_output items emitted by OutputConverter had no id on
the wire.
OutputItemFunctionToolCallOutput's public ctor only sets CallId and
Output; Id is read-only and only the SDK's internal ctor populates
it. OutputItemBuilder<T>.ApplyAutoStamps fills ResponseId and
AgentReference but not Id, so the itemId passed to
AddOutputItem<T>(itemId) was used only for event sequencing and the
serialized item went out with id=null.
Switch to stream.OutputItemFunctionCallOutput(callId, output), the
SDK convenience method that uses the internal ctor and stamps the
id. Add a regression test asserting the added/done events carry a
non-empty matching Id.

* ci: free disk space and relocate NuGet cache on ubuntu runners
The ubuntu-latest dotnet-build/test jobs were hitting No space left on device because the runner image only ships ~14 GB free on /. The full multi-TFM build plus the dotnet pack + console-app install-check exhausts that easily.
Add a reusable composite action .github/actions/free-runner-disk-space that runs on Linux runners only and:
* removes pre-installed toolchains we never use here (Android SDK, GHC/Haskell, CodeQL, PyPy, Ruby, Go, boost, vcpkg, etc.), prunes docker images, and disables swap (reclaims ~25-30 GB on /)
* relocates the NuGet package cache to /mnt/nuget via NUGET_PACKAGES env, since /mnt has ~75 GB free on hosted runners
Wire the action into the four ubuntu-touching jobs in dotnet-build-and-test.yml (dotnet-build, dotnet-test, dotnet-foundry-hosted-it, dotnet-test-functions). The action self-guards with runner.os == 'Linux' so the matrix legs that run on windows are unaffected.

on subsequent turns, so participant replies never reached the manager's
ChatHistory. The manager kept re-dispatching the same speaker every
round until MaxRounds.
Append the incoming messages to taskContext.ChatHistory before running

* Bump Azure.AI.AgentServer.* package versions
* Align Azure.Core/System.ClientModel to AgentServer transitive deps
Bump Azure.Core 1.55->1.56 and System.ClientModel 1.11->1.12 to match Azure.AI.AgentServer.* requirements, and add explicit references in transitive-pinning-off Foundry consumers to avoid CS1705/MSB3277 version conflicts.
* test: reshuffle .NET Workflow tests in preparation for Outputs overhaul
Phase 1 of the .NET Workflows outputs overhaul (see
working/implementation-plan.md). Pure moves/renames in
dotnet/tests/Microsoft.Agents.AI.Workflows.UnitTests; no production code
changes, no new test cases. The split keeps each orchestration mode in
its own source file so the upcoming tag-aware and orchestration-default
test additions land on clean diffs.
Renames:
* WorkflowBuilderSmokeTests.cs -> WorkflowBuilderTests.cs (with class
rename to match). The scope is no longer "smoke"-only once subsequent
phases add tag-aware builder tests.
* InputWaiterAndOutputFilterTests.cs -> InputWaiterTests.cs +
OutputFilterTests.cs. The file already declared the two test classes
separately; this split simply gives each its own file so the
output-filter cases have a dedicated home for tag-aware additions.
Split of AgentWorkflowBuilderTests.cs:
* AgentWorkflowBuilderTests.cs is now the outer
`public static partial class AgentWorkflowBuilderTests` holding the
shared test helpers (DoubleEchoAgent + session + WithBarrier variant,
WorkflowRunResult, RunWorkflow* methods) bumped from `private` to
`internal` so the new top-level GroupChatWorkflowBuilderTests in the
same assembly can reach them.
* AgentWorkflowBuilder.SequentialTests.cs (nested SequentialTests):
BuildSequential_InvalidArguments_Throws,
BuildSequential_AgentsRunInOrderAsync.
* AgentWorkflowBuilder.ConcurrentTests.cs (nested ConcurrentTests):
BuildConcurrent_InvalidArguments_Throws,
BuildConcurrent_AgentsRunInParallelAsync.
Sequential and Concurrent are kept as nested classes because they're
modes of the same `AgentWorkflowBuilder` static factory and do not
produce dedicated builder types.
New file:
* GroupChatWorkflowBuilderTests.cs (top-level): the existing
BuildGroupChat_* and GroupChatManager_* cases moved out of the old
AgentWorkflowBuilderTests file. They exercise the
`GroupChatWorkflowBuilder` type (returned by
`AgentWorkflowBuilder.CreateGroupChatBuilderWith`), so a dedicated
top-level test class - matching the convention reserved by the plan
for HandoffWorkflowBuilderTests / MagenticWorkflowBuilderTests - is
the right home. Cross-class helper references qualify with
`AgentWorkflowBuilderTests.DoubleEchoAgent` and
`AgentWorkflowBuilderTests.RunWorkflowAsync`.
The outer partial class is `static` (and nested classes carry the
instance test methods) because the outer holds only static helpers;
this satisfies CA1052 without suppressions and is invisible to xUnit
discovery, which finds tests on the nested classes as
`AgentWorkflowBuilderTests.SequentialTests.*` etc.
Validation: `dotnet build` clean on both target frameworks; all 547
tests in Microsoft.Agents.AI.Workflows.UnitTests pass on net10.0.

* feat: introduce OutputTag, Futures, and tag-aware WorkflowBuilder API
Phase 2 of the .NET Workflows outputs overhaul. Additive code change
only - no observable runtime behavior change. The runner still uses the
legacy bypass for AgentResponse / AgentResponseUpdate payloads, and the
new `Futures.EnableAgentResponseOutputTaggingAndFiltering` flag defaults
to false. Phase 3 will wire the flag into the runner; this commit only
introduces the types and the builder API.
New public surface:
* `OutputTag` (readonly struct): wraps a string Value with ordinal
equality (IEquatable, GetHashCode, == / !=) so it can participate as a
HashSet element. Internal ctor closes the set. One public singleton:
`OutputTag.Intermediate`. Terminal / regular outputs carry no tag
(empty Tags set). JSON-serialized as a bare string via
[JsonConverter(typeof(OutputTagJsonConverter))], with the converter
rehydrating to the well-known singleton on read.
* `Futures` (static class): hosts opt-in pre-GA behavior switches.
First flag is `EnableAgentResponseOutputTaggingAndFiltering`; XML doc
captures the v2.0.0 obsoletion / v3.0.0 removal lifecycle.
* `WorkflowOutputEvent.Tags`: `HashSet<OutputTag>` exposed directly
(concrete collection, matches the JSON-serialization convention used
for `WorkflowInfo.OutputExecutorIds`). Never null; empty for legacy /
terminal events. New ctors take a single `OutputTag` or
`IEnumerable<OutputTag>?`; the existing (data, executorId) ctor
remains and produces an untagged event. `HasTag(OutputTag)` helper.
`AgentResponseEvent` and `AgentResponseUpdateEvent` gain matching
tag-accepting ctors forwarding to the base.
* `WorkflowOutputEventExtensions.IsIntermediate(this WorkflowOutputEvent)`:
extension method returning `evt.HasTag(OutputTag.Intermediate)`. The
preferred way to ask "is this an intermediate output?" without
reaching into the Tags set.
* `WorkflowBuilder.WithOutputFrom(IEnumerable<ExecutorBinding>, OutputTag)`
and `WorkflowBuilder.WithOutputFrom(ExecutorBinding, OutputTag)`:
forward-looking tagged overloads. The IEnumerable form is the primary
tagged surface; the single-executor form is a convenience for the
common one-executor case. Currently usable for the
`OutputTag.Intermediate` singleton; will become the primary surface
once the `OutputTag` constructor is opened to user-defined tags in
a future release. Callers in this release should prefer the
intent-specific `WithIntermediateOutputFrom` extension for the
intermediate case. Tags accumulate across repeated calls; same tag
repeated dedupes via the HashSet.
* `WorkflowBuilderExtensions.WithIntermediateOutputFrom(this WorkflowBuilder, IEnumerable<ExecutorBinding>)`:
helper that forwards to `WithOutputFrom(executors, OutputTag.Intermediate)`.
Takes an IEnumerable (matching the tagged WithOutputFrom shape) -
callers pass collection literals: `builder.WithIntermediateOutputFrom([a, b])`.
XML doc remarks call out the Futures-flag interaction and the
AIAgent-payload forwarding contract.
Internal shape changes:
* `WorkflowBuilder._outputExecutors`: HashSet<string> -> Dictionary<
string, HashSet<OutputTag>>. The value set is empty for executors
designated only via the untagged WithOutputFrom; contains Intermediate
(and possibly future tags) otherwise.
* `Workflow.OutputExecutors`: HashSet<string> -> Dictionary<string,
HashSet<OutputTag>>.
* `OutputFilter.CanOutput`: `Contains(id)` -> `ContainsKey(id)`.
* `WorkflowInfo.OutputExecutorIds`: HashSet<string> -> Dictionary<
string, HashSet<OutputTag>>, with a custom JsonConverter that reads
both the new map shape (`{id: ["intermediate", ...]}`) and the legacy
array shape (`[id1, id2]`, where each id is treated as an untagged
output). Always writes the map shape. IsMatch updated to compare
per-id tag sets.
Tests landing in this commit (per the test-with-feature principle):
* `OutputTagTests.cs` (6 tests): KnownValues, EqualityIsOrdinalOnValue,
DefaultStructValueIsDistinct (default(OutputTag) does not collide
with the Intermediate singleton in a HashSet),
GetHashCodeMatchesEquals, JsonConverter_RoundtripsValueAsString,
ConstructorIsInternal (reflection-based assertion that the (string)
ctor is `internal`).
* `WorkflowBuilderTests.cs` adds 7 new tests pinning the builder
API contract: RegistersWithEmptyTagSet, AddsIntermediateTag,
MultipleExecutorsAllUntagged, ThenIntermediate_AccumulatesTags,
RepeatedDedupes, OnlyRegistersWithoutPriorWithOutputFrom,
TracksExecutorBinding.
* `BackwardsCompatibility/JsonCheckpointSerializationTests.cs`
(new folder + file, 5 tests): event-level ctor contract tests
(single-tag, no-tag, multi-tag — the last with a custom tag);
IsIntermediate() asserted; load-bearing JSON BC tests for
`WorkflowInfo.OutputExecutorIds` -
`WorkflowOutputExecutorsReadsLegacyArrayShape` (legacy ids map to
empty tag sets) and `WorkflowOutputExecutorsWritesMapShape`.
The plan's three JSON round-trip tests for `WorkflowOutputEvent.Tags`
were dropped: `WorkflowEvent` is not currently a serialized checkpoint
shape (see the comment in WorkflowsJsonUtilities.cs about events not
being persisted), so there is no real back-compat surface to pin
through JSON. They are substituted with in-process ctor/property
round-trip tests that exercise the `Tags` / `HasTag` / `IsIntermediate`
contract.
Validation: full `Microsoft.Agents.AI.Workflows.UnitTests` suite runs
green on net10.0 (565 passing, 0 failing). Core library builds clean
on net472, netstandard2.0, net8.0, net9.0, and net10.0. Test project
builds clean on net472 + net10.0.

* feat: route AgentResponse(Update) through the output filter under a Futures flag
`InProcessRunnerContext.YieldOutputAsync` historically special-cased AgentResponse and
AgentResponseUpdate payloads: it built the typed event subclass and emitted it directly,
bypassing the output filter. Rewrites the method so that:
- When `Futures.EnableAgentResponseOutputTaggingAndFiltering` is `false` (the current
default), AgentResponse(Update) keep the legacy bypass — emitted as
AgentResponseEvent / AgentResponseUpdateEvent with no tags. Existing callers see no
behavior change.
- When the flag is `true`, AIAgent payloads flow through the output filter just like
every other payload type: undesignated sources are dropped, and the emitted event
carries the source's tag set (empty for terminal `WithOutputFrom`, `{Intermediate}`
for `WithIntermediateOutputFrom`, the set union when both designations apply).
Non-AIAgent (POCO) outputs also now carry the source's tag set on the emitted
WorkflowOutputEvent unconditionally — additive, since no existing assertion inspected
Tags. Subclass events (`AgentResponseEvent` / `AgentResponseUpdateEvent`) continue to
be emitted under both modes so `switch (evt) { case AgentResponseEvent: ... }`
consumer code keeps matching.
Adds `OutputFilter.TryGetTags` as the tag-aware lookup used by the runner.
`OutputFilter.CanOutput` is kept (still used by the existing sync tests in
`OutputFilterTests.cs`).
Tests
-----
- `Futures/Futures.AgentResponseOutputFilteringAndTaggingTests.cs` (new): the F1–F13
matrix from the plan, covering every combination of `(flag on/off) × (designation)
× (payload shape)`. Uses a `FuturesScope` IDisposable + a `FuturesSerial` xUnit
collection (DisableParallelization = true) to keep the process-global flag from
leaking across parallel tests.
- `OutputFilterTests.cs`: four new `Test_OutputFilter_…` cases for the `TryGetTags`
surface (empty-tag-set for terminal designation, `{Intermediate}` for intermediate
designation, union for accumulated designation, `false` for unregistered).
582/582 unit tests pass on net10.0 (565 baseline + 17 new).

* feat: tag-aware defaults and designation API on orchestration builders
Aligns the .NET orchestration builders with Python's output / intermediate-output
distinction. Each builder either applies a Python-aligned default designation set or
replays the user's explicit `WithOutputFrom` / `WithIntermediateOutputFrom` calls,
never both.
Static `AgentWorkflowBuilder.BuildSequential` / `BuildConcurrent` apply defaults
unconditionally (no user-facing fluent surface to take control through):
- Sequential: terminal `end` + every agent designated intermediate.
- Concurrent: terminal `end` + every agent and per-agent accumulator designated
intermediate.
The three fluent instance builders memoize agent-typed designation calls in a
`Dictionary<AIAgent, HashSet<OutputTag>>` (empty set = terminal-only, non-empty =
intermediate tag(s)) so repeated calls dedupe naturally. They replay the entries
at `Build()` time, suppressing defaults when any call has been made:
- `HandoffWorkflowBuilder` / `HandoffWorkflowBuilderCore<TBuilder>` (also picked up
by the obsolete `HandoffsWorkflowBuilder` via inheritance).
Default: terminal `HandoffEnd` + every handoff agent intermediate.
(Bug fix: legacy code relied on `WithOutputFrom(end)` to bind `HandoffEnd`. The
new explicit-designation path bypasses that, so `Build()` now calls
`BindExecutor(end)` unconditionally to keep validation happy.)
- `GroupChatWorkflowBuilder` — default: terminal host + every participant intermediate.
- `MagenticWorkflowBuilder` — default: terminal orchestrator + every team member
intermediate.
Designating a non-participant agent throws `InvalidOperationException`.
The bare `WorkflowBuilder` default is unchanged — only the orchestration-style
builders gain implicit defaults, matching the plan's non-goal.
Tests
-----
- `AgentWorkflowBuilder.SequentialTests` / `.ConcurrentTests`: one default-spec
assertion each.
- `GroupChatWorkflowBuilderTests`: defaults-match-spec, explicit-replaces-defaults,
non-participant throws.
- `HandoffWorkflowBuilderTests` (new file): same three.
- `MagenticWorkflowBuilderTests` (new file): same three.
593/593 unit tests pass on net10.0 (582 baseline + 11 new).

* feat: WorkflowHostAgent forwards AgentResponseEvent unconditionally under Futures-on
Aligns the .NET Workflow-as-Agent surface with Python `as_agent`. Under
`Futures.EnableAgentResponseOutputTaggingAndFiltering = true`,
`WorkflowSession.InvokeStageAsync` now forwards `AgentResponseEvent`
unconditionally — joining `AgentResponseUpdateEvent` in ignoring the host's
`includeWorkflowOutputsInResponse` switch. That switch keeps governing the
generic `WorkflowOutputEvent` path for non-AIAgent payloads, where it is
further short-circuited by an `IsIntermediate()` check (tagged intermediate
outputs always surface).
Under Futures-off the legacy asymmetry is preserved: `AgentResponseUpdateEvent`
always forwarded, `AgentResponseEvent` gated by `includeWorkflowOutputsInResponse`.
Back-compat: with `Futures.EnableAgentResponseOutputTaggingAndFiltering` left at
its default `false`, observable behavior is identical to before.
`Futures` documentation gains a remark explaining the `Workflow.AsAIAgent()`
interaction in both flag states.
Runner fix
----------
`InProcessRunnerContext.YieldOutputAsync` now skips `Executor.CanOutput` for
AgentResponse-shaped payloads under both Futures branches. `AIAgentHostExecutor`
doesn't declare AgentResponse(Update) in its `Yields` set, so the historical
legacy bypass had silently skipped the check; Phase 3's Futures-on path was
running it and would reject AIAgent payloads. AIAgent-shaped payloads are now
always a valid output shape, matching the legacy bypass semantics.
Phase 4 follow-on
-----------------
Switched the three orchestration-builder designation-replay loops to iterate
`Dictionary.Keys` with a value lookup instead of constructing/destructuring
`KeyValuePair<,>`. Cleaner shape and avoids the netstandard2.0 / net472
`KeyValuePair<,>.Deconstruct` unavailability that surfaced when this branch
multi-TFM-built.
Tests
-----
`WorkflowHostSmokeTests.IntermediateForwarding` (new nested class, 6 tests):
- intermediate AgentResponse forwarded past the include-outputs gate (Futures on)
- terminal AgentResponse forwarded unconditionally (Futures on)
- terminal AgentResponse gated by include flag (Futures off, legacy)
- undesignated AIAgent executor emits no AgentResponseEvent under Futures-on
- legacy bypass still emits AgentResponseEvent under Futures-off
- intermediate tag is observable via `update.RawRepresentation`
The class joins the `FuturesSerial` xUnit collection so the process-global flag
is serialized against other Futures-toggling tests.
599/599 unit tests pass on net10.0 (593 baseline + 6 new).

* feat: SequentialWorkflowBuilder and ConcurrentWorkflowBuilder, OrchestrationBuilderBase
Promotes the Sequential and Concurrent orchestration shapes to first-class fluent
builder classes, matching Handoff / GroupChat / Magentic. Users can call
`WithOutputFrom(agents)` / `WithIntermediateOutputFrom(agents)` to control which
agents are designated output / intermediate sources; when no designation call is
made, the Python-aligned defaults apply (terminal aggregator output + every agent
intermediate; Concurrent also tags per-agent accumulators).
`AgentWorkflowBuilder.BuildSequential(...)` and `BuildConcurrent(...)` are kept
and now delegate to the new builders; observable behavior unchanged. Five static
factories now mirror each other:
- `AgentWorkflowBuilder.CreateSequentialBuilderWith(params IEnumerable<AIAgent>)`
- `AgentWorkflowBuilder.CreateConcurrentBuilderWith(params IEnumerable<AIAgent>)`
- `AgentWorkflowBuilder.CreateHandoffBuilderWith(AIAgent)` (already existed)
- `AgentWorkflowBuilder.CreateGroupChatBuilderWith(Func<...>)` (already existed)
- `AgentWorkflowBuilder.CreateMagenticBuilderWith(AIAgent)` (new)
OrchestrationBuilderBase
------------------------
New abstract `OrchestrationBuilderBase<TBuilder>` unifies the shared fluent
surface across all five orchestration builders: `WithName`, `WithDescription`,
`WithOutputFrom`, `WithIntermediateOutputFrom`, and the
`ApplyOutputDesignations(builder, agentMap, kind, applyDefaults)` helper that
either replays the user's designations or invokes the orchestration-specific
defaults.
Removes ~150 LOC of duplicated designation-management code from the four
non-Handoff builders, plus the equivalent from `HandoffWorkflowBuilderCore`.
Tests
-----
- New `SequentialWorkflowBuilderTests.cs` / `ConcurrentWorkflowBuilderTests.cs`
(replace the old `AgentWorkflowBuilder.{Sequential,Concurrent}Tests.cs`
nested-class files). Method names normalized to
`Test_<BuilderType>_<Scenario>[Async]`.
- Shared helpers (`DoubleEchoAgent`, `DoubleEchoAgentWithBarrier`,
`WorkflowRunResult`, `RunWorkflow*`) moved from the old
`AgentWorkflowBuilderTests` partial class into a new
`OrchestrationTestHelpers` static class in `OrchestrationTestHelpers.cs`.
Downstream test files (Group Chat, Handoff, Sequential, Concurrent) updated
to qualify with `OrchestrationTestHelpers.*`.
- A new `AgentWorkflowBuilderTests.cs` covers the static surface directly:
`BuildSequential` / `BuildConcurrent` invariants and aggregator wiring, plus
null-rejection + round-trip checks for every `Create*BuilderWith` factory.
- New AsAgent intermediate-suppression tests on a nested `AsAgentForwarding`
class for each of Sequential and Concurrent: build with only the terminal
agent designated via `WithOutputFrom`, run via `AsAIAgent(...)`, assert via
`AgentResponseUpdate.AuthorName` that intermediate agents do not surface.
Both join the `FuturesSerial` collection.
- New `Test_<Builder>_WithDescriptionPropagatesToWorkflow` smoke tests on
Sequential and Concurrent (newly available via the base class).
625/625 unit tests pass on net10.0.
