b59a854fcd Fix integration test worker crashes in Azure Functions on Py3.13 (#4260)
* Initial plan

* Fix integration test worker crashes on Python 3.13

Three changes to prevent pytest-xdist workers from crashing during
Azure Functions integration tests:

1. Add `start_new_session=True` to subprocess on Linux so signals
   (e.g. from test-timeout) cannot propagate between the func host
   and the xdist worker process.

2. Add an overall 100-second budget to the fixture setup loop so
   the retry logic never exceeds the 120-second test timeout. When
   pytest-timeout's thread method fires during fixture setup and the
   thread doesn't respond, it calls os._exit() which kills the
   xdist worker – this is the root cause of the "Not properly
   terminated" crashes.

3. Remove the `UV_PYTHON: "3.10"` workaround from both workflow
   files so integration tests actually run on Python 3.13.

* Fix func worker segfault on Python 3.13 by redirecting worker to Python 3.12

The Azure Functions Python worker crashes with SIGSEGV (exit code 139)
on Python 3.13 due to protobuf C extension (google._upb) compatibility
issues.  When the test runner uses Python >=3.13, the conftest now
automatically finds a compatible Python 3.10-3.12 and sets
languageWorkers__python__defaultExecutablePath so the func host uses
it for the worker process.

The CI setup action also ensures Python 3.12 is available on the
runner, falling back to uv python install if the system doesn't have
it.

* Address code review: add path validation, clarify version range and config key format

* Run func worker natively on Python 3.13 by disabling dependency isolation

Replace the Python 3.12 redirect workaround with the proper fix:
set PYTHON_ISOLATE_WORKER_DEPENDENCIES=0 on Python >=3.13.

The segfault (exit code 139) is caused by the Azure Functions worker's
module isolation mechanism conflicting with protobuf's C extensions
(google._upb) on Python 3.13.  Disabling isolation lets the worker
load dependencies from the app's own environment, which avoids the
crash while keeping everything running on Python 3.13.

5affc9c333 Python: Reorganize A2A samples and use package A2AExecutor (#6165)
* Reorganize A2A samples: client demos in 02-agents, use package A2AExecutor

- Move client samples (agent_with_a2a, a2a_agent_as_function_tools) to samples/02-agents/a2a/
- Add new concept samples: polling, stream reconnection, protocol selection
- Replace sample agent_executor.py with package-level A2AExecutor (stream=True)
- Update 04-hosting/a2a to focus on server-side, point to 02-agents for clients
- Add README.md for the new 02-agents/a2a/ sample collection

* Fix streaming artifact coalescing and address PR review feedback

A2AExecutor fix:
- Generate a stable artifact_id per stream in _run_stream so all streaming
  chunks share the same ID, enabling proper append=True coalescing per the
  A2A spec (TaskArtifactUpdateEvent with same artifactId).
- Previously, item.message_id was None for OpenAI/Foundry streaming updates,
  causing the SDK to generate a new random UUID per token (100+ separate
  artifacts instead of 1 appended artifact).

Sample improvements:
- Replace join workaround with response.text now that coalescing works
- Add background=True to stream reconnection resume call (required for
  continuation token emission on in-progress tasks)
- Fix type ignore specificity in polling sample

07a1e83492 .NET: Forward Magentic participant replies to manager (#6156)
MagenticOrchestrator.TakeTurnAsync dropped the `messages` parameter
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
the coordination round (matches Python's _handle_response).

Adds RecordingReplayAgent + regression test that asserts the worker's
reply reaches round-2's progress-ledger call.

dd9a4b6321 Python: [A2A] Set message_id on AgentResponseUpdate for message-bearing paths (#6163)
Map A2A protocol message_id to AgentResponseUpdate.message_id in two paths
where it was previously omitted, aligning with .NET behavior:

1. Standalone A2AMessage: set message_id=msg.message_id (matches .NET
   ConvertToAgentResponseUpdate(Message) which sets both ResponseId and
   MessageId to message.MessageId)

2. TaskStatusUpdateEvent (terminal/input_required): set
   message_id=message.message_id (matches .NET which sets
   MessageId=statusUpdateEvent.Status.Message?.MessageId)

Fixes #5949

Jacob AlberandGitHub 1fccf16f11 feat: Remove [Experimental] tag from .NET Orchestrations (#6164) 2026-05-29 00:03:19 +00:00
8ed2159c4b .NET: Workflow Outputs Overhaul: Support Tagging, Filtering Agent Outputs (#6045)
* 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.

b000a2cf51 Python: Adding AgentFileStore and FileAccessProvider to support file access operations. (#6099)
* Adding AgentFileStore and FileAccessProvider to support file ased operations for agents.

* Address PR review feedback on FileAccessProvider

- Probe symlinks on the unresolved candidate path so in-root symlinks
  cannot silently pass and out-of-root symlinks surface the correct
  error message.
- Validate matching_lines elements in FileSearchResult.from_dict and
  raise a clean ValueError for non-mapping entries.
- Cap search regex pattern length (256 chars) via a new
  _compile_search_regex helper to mitigate ReDoS, and surface the cap
  in the file_access_search_files tool description.
- Skip non-UTF-8 files during filesystem search instead of aborting
  the entire directory walk.
- Replace the module-scope trailing string in the data-processing
  sample with comments to avoid Ruff B018.
- Remove the checked-in working/region_totals.md sample artifact so
  the save flow works from a clean checkout.
- Expand the Windows stdout reconfiguration comment in task_runner.py
  for clarity.
- Add tests for invalid/oversize regex, non-UTF-8 file search, and
  in-root symlink rejection.

* Fix mypy redundant-cast in FileSearchResult.from_dict

Use cast(list[object], ...) instead of cast(list[Any], ...) so the
cast represents a real type change (lists are invariant) and is no
longer flagged by mypy as redundant, while still satisfying pyright's
reportUnknownVariableType. Matches the existing pattern in _memory.py.

* Tighten path normalization and directory resolution in FileAccess

- _normalize_relative_path now strips surrounding whitespace up front
  so leading/trailing spaces never leak into file segments, and
  rejects trailing path separators for file paths so 'foo/' is no
  longer silently coerced to 'foo'.
- FileSystemAgentFileStore._resolve_safe_directory_path normalizes
  with is_directory=True and maps an empty normalized result to the
  root. This matches InMemoryAgentFileStore so whitespace-only
  directory inputs resolve to the root instead of raising.
- Added tests for whitespace stripping, trailing-separator rejection,
  and whitespace-only directory listing on the filesystem store.

Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

* Harden FileAccess search and atomic save in store API

- Add wall-clock timeout (10s) around regex scans so a pathological pattern (e.g. `(a+)+`) below the length cap cannot stall the event loop.
- Offload the InMemoryAgentFileStore regex scan to a worker thread, matching the filesystem store.
- Fail closed when `Path.is_symlink` raises during the safe-path probe so a permission error cannot silently bypass the symlink/reparse-point rejection.
- Add `overwrite: bool = True` to `AgentFileStore.write_file`; the in-memory store performs the check under the existing lock and the filesystem store uses `open(mode='x')` so concurrent callers cannot race past `overwrite=False`.
- `file_access_save_file` now relies on the atomic store call instead of a separate `file_exists` round-trip.

* Fix Python 3.10 timeout handling and add directory arg to list/search tools

- Catch asyncio.TimeoutError in _run_search_with_timeout. In Python 3.10
  asyncio.wait_for raises asyncio.exceptions.TimeoutError, which is
  distinct from the builtin TimeoutError (the two were unified in 3.11).
  Catching the asyncio alias works on every supported version.
- Add an optional directory parameter to file_access_list_files and
  file_access_search_files so agents can enumerate / scope searches to
  nested folders, not just the store root.

* Address FileAccess review feedback: case, errors, signal, TOCTOU

- InMemoryAgentFileStore now stores (display_name, content) so list_files
  and search_files return the original-case names callers wrote, matching
  the behaviour of FileSystemAgentFileStore on case-preserving filesystems
  and removing the silent in-memory vs. on-disk contract divergence.
- FileSystemAgentFileStore.read_file raises ValueError instead of letting
  UnicodeDecodeError bubble for binary / non-UTF-8 input, restoring
  symmetry with search_files (which still skips) and giving the tool
  layer a recoverable type to translate.
- Tool wrappers now catch ValueError and OSError around every operation
  and surface them as readable strings, so 'you used ..' and 'the file
  already exists' are both reported to the model the same way instead of
  the former crashing out as an unhandled exception.
- _search_files_sync logs per skipped non-UTF-8 file at WARNING and an
  aggregate INFO summary so operators can distinguish 'no matches' from
  'half the corpus was unreadable'.
- FileSystemAgentFileStore softens its docstrings to acknowledge the
  inherent probe-then-open TOCTOU window. On POSIX both read and write
  now pass O_NOFOLLOW so the kernel refuses if the leaf segment becomes
  a symlink between the probe and the open. Windows has no equivalent
  flag; the limitation is documented.
- Tests cover: case preservation on list/search, ValueError on non-UTF-8
  read at the store and tool layer, tool-layer string responses for
  path-traversal and oversized-regex inputs, search-skip log output,
  symlink rejection on delete/search/list, and symlinked intermediate
  directory rejection.

* Address FileAccess nit comments: docstrings, enumerate, opt-in delete approval

- Expand FileSearchMatch/FileSearchResult.to_dict docstrings to explain why
  the override is needed (__slots__ defeats the mixin's __dict__ iteration)
  and why exclude/exclude_none are accepted-but-ignored (mixin signature
  compatibility for callers like to_json).
- Use enumerate(lines, start=1) in _search_file_content so the +1 below is
  no longer needed; rename loop variable to line_number for clarity.
- Add opt-in require_delete_approval: bool = False on FileAccessProvider.
  When True, file_access_delete_file is registered with approval_mode
  'always_require' so the host must approve every delete. Default False
  preserves current behaviour and matches the .NET reference, but
  deployments that want a safer-by-default posture can enable it.
- Add tests covering both delete approval modes.

* FileAccess: require delete approval by default

Flip the default for FileAccessProvider(require_delete_approval=...) from
False to True so destructive deletes are gated by host approval out of the
box. Callers that want the previous autonomous behaviour (which matches the
.NET reference) can pass require_delete_approval=False.

Tests updated accordingly.

f7c5b8d108 Python: [Breaking] Refactor Skill API to async resource and script lookup (#6135)
Port of .NET commit 08541ee5a9.

Replace property-based Skill.content/resources/scripts with async
by-name lookup methods:
- content property -> async get_content() -> str
- resources property -> async get_resource(name) -> SkillResource | None
- scripts property -> async get_script(name) -> SkillScript | None

SkillsProvider now always includes all three tools (load_skill,
read_skill_resource, run_skill_script) and both instruction blocks
regardless of whether any skills have resources or scripts.

ClassSkill retains resources/scripts properties as overridable hooks
for subclass reflection-based discovery.

3db2004e49 Python: read headers defensively to support stream wrappers without .headers (#6028) (#6029)
`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`.

efdabd56dc feat(a2a): add A2AAgentSession with reference_task_ids and input-required support (#5980)
* 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

* addressed comments

* 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.

Closes #5937

Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

* Address review: remove message task_id tracking, defensive fallbacks, and input_required flag

- Do not track task_id from Message payloads (simple interactions
  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.

1d301af7d2 .NET: Add MCP-based skills support (skill-md type) (#6108)
* Add MCP-based skills support

- Add AgentMcpSkill, AgentMcpSkillResource, AgentMcpSkillsSource, and McpSkillIndex to Microsoft.Agents.AI.Mcp
- Add AgentSkillsProviderBuilderMcpExtensions for DI integration
- Add Agent_Step06_McpBasedSkills sample project
- Add unit tests for AgentMcpSkillsSource
- Update solution file and project references

* Remove unnecessary [Experimental] attributes from MCP package

The package is already alpha, so the [Experimental] attribute is redundant.
Removed from both AgentSkillsProviderBuilderMcpExtensions and
AgentMcpSkillsSource classes.

* Make Agent_Step06_McpBasedSkills self-contained and add to verify-samples

Embed an internal MCP server (launched via --server flag as a child process)
that serves skill://index.json and skill://unit-converter/SKILL.md resources,
replacing the external MCP_SKILLS_ENDPOINT dependency. The sample now uses
StdioClientTransport and a fixed prompt instead of an interactive loop.

Added SampleDefinition to AgentsSamples.cs for automated verification.

d5c07f2623 Python: feat(foundry): add to_prompt_agent / deploy_as_prompt_agent (experimental) (#5959)
* 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.

* fix(foundry): address review comments on to_prompt_agent 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.

* fix(foundry): restore missing-model ValueError in to_prompt_agent

The check was accidentally dropped while reworking docstrings in the
previous commit. Test `test_to_prompt_agent_rejects_missing_model`
exercises this path and was failing on CI as a result.

Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

* refactor(foundry): rename deploy_as_prompt_agent -> create_prompt_agent

Renames the helper across the foundry package, core lazy-loader stubs,
tests, README and samples. The new name better matches the action
performed (a prompt-agent definition is created in Foundry) and is
consistent with the surrounding ''create_*'' API surface.

Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

* refactor(foundry): drop create_prompt_agent, enrich to_prompt_agent params

Remove the create_prompt_agent helper and consolidate on to_prompt_agent.
Expose every PromptAgentDefinition parameter that has either an Agent
Framework equivalent (sourced from default_options) or no equivalent
(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.

Tests, README, and creating_prompt_agents.py sample updated to reflect the
new single-source model.

Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

* docs(foundry): consolidate prompt-agent sample

Drop creating_prompt_agents.py (the publish-only variant) and rename
using_prompt_agents.py to foundry_prompt_agents.py so the single sample
covers the full convert -> publish -> connect -> run loop. Update the
README link list accordingly.

Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

* docs(foundry): run local Agent + deployed agent in same sample

Add an agent.run() call against the local Agent before publishing, then run
the deployed prompt agent on the same query. Expand the docstring with a
compare-and-contrast covering runtime/latency, configurability, and
persistence/sharing differences between the two execution paths.

Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

* test(foundry): cover conflicting response_format + text.format in to_prompt_agent

Exercises the ValueError path when a Pydantic response_format would overwrite
an explicit text.format mapping with a different shape. Lifts _chat_client.py
coverage from 89% to 90%.

Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

* 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.

* 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.

* fix(ci): correct linkspector ignorePattern typo (./pulls -> ./pull)

GitHub PR URLs use the singular segment /pull/N (compare to /issues/N
for issues). The existing './pulls' ignore pattern never matched
anything as a result, so legitimately stale PR links (e.g. PRs deleted
from forks) surface as linkspector failures on unrelated PRs.

This is the same convention the './issues' rule above already follows.
Fixes the markdown-link-check failure on a dangling link in
dotnet/src/Microsoft.Agents.AI.DurableTask/CHANGELOG.md.

200488cb08 Python: Add Python parity sample for invoking Foundry Toolbox tools from declarative workflows (#5933)
* 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.
