Python: Add OpenTelemetry instrumentation to ClaudeAgent (#4278 ) (#4326 )

* Python: Add OpenTelemetry instrumentation to ClaudeAgent (#4278)

Add inline telemetry to ClaudeAgent.run() so that enable_instrumentation()
emits invoke_agent spans and metrics. Covers both streaming and
non-streaming paths using the same observability helpers as
AgentTelemetryLayer. Adds 5 unit tests for telemetry behavior.

Co-Authored-By: amitmukh <amimukherjee@microsoft.com>

* Address PR review feedback for ClaudeAgent telemetry

- Add justification comment for private observability API imports
- Pass system_instructions to capture_messages for system prompt capture
- Use monkeypatch instead of try/finally for test global state isolation

Co-Authored-By: Claude <noreply@anthropic.com>

* Adopt AgentTelemetryLayer instead of inline telemetry

Restructure ClaudeAgent to inherit from AgentTelemetryLayer via a
_ClaudeAgentRunImpl mixin, eliminating duplicated telemetry code and
private API imports.

MRO: ClaudeAgent → AgentTelemetryLayer → _ClaudeAgentRunImpl → BaseAgent

- Remove inline _run_with_telemetry / _run_with_telemetry_stream methods
- Remove private observability helper imports (_capture_messages, etc.)
- Add default_options property mapping system_prompt → instructions
- Net -105 lines by reusing core telemetry layer

Co-Authored-By: amitmukh <amitmukh@users.noreply.github.com>
Co-Authored-By: Claude <noreply@anthropic.com>

* Fix mypy: align _ClaudeAgentRunImpl.run() signature with AgentTelemetryLayer.run()

Remove explicit `options` parameter from mixin's run() signature and
extract it from **kwargs to match AgentTelemetryLayer's signature.
Also align overload return types (ResponseStream, Awaitable) to match.

Co-Authored-By: Claude <noreply@anthropic.com>

* Introduce RawClaudeAgent following framework's RawAgent/Agent pattern

Replace private _ClaudeAgentRunImpl mixin with public RawClaudeAgent
class that contains all core logic (init, run, lifecycle, tools).
ClaudeAgent becomes a thin wrapper that adds AgentTelemetryLayer.

- RawClaudeAgent(BaseAgent): full implementation without telemetry
- ClaudeAgent(AgentTelemetryLayer, RawClaudeAgent): adds OTel tracing
- Export RawClaudeAgent from package __init__.py

Users who want to skip telemetry or provide their own can use
RawClaudeAgent directly.

Co-Authored-By: Claude <noreply@anthropic.com>

* Address review nits: trim RawClaudeAgent docstring, fix import paths

- Simplify RawClaudeAgent docstring to a single basic example (not the
  primary entry point for most users)
- Use agent_framework.anthropic import path in docstrings instead of
  direct agent_framework_claude path
- Add RawClaudeAgent to agent_framework.anthropic lazy re-exports

Python: Fix StandardMagenticManager to propagate session to manager agent (#4409 )

* Fix #4371: Propagate session to manager agent in StandardMagenticManager

StandardMagenticManager._complete() was calling self._agent.run(messages)
without passing a session. This caused context providers (e.g.
RedisHistoryProvider) configured on the manager agent to silently fail,
as each call created a new ephemeral session with a different session_id.

Changes:
- Create an AgentSession in StandardMagenticManager.__init__()
- Pass session=self._session in _complete() calls to agent.run()
- Persist/restore the session in checkpoint save/restore methods
- Add regression tests for session propagation and checkpoint round-trip

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

* Add type: ignore[reportPrivateUsage] to private attribute assertions in tests

Address PR review feedback: add # type: ignore[reportPrivateUsage] comments
to _session attribute accesses in the new regression tests, matching the
existing convention used elsewhere in test_magentic.py (e.g., lines 401-406).

The @pytest.mark.asyncio decorator is not needed because pyproject.toml
sets asyncio_mode = "auto".

Python: Fix IndexError when reasoning models produce reasoning-only messages in Magentic-One workflow (#4413 )

* Fix IndexError when reasoning models return no text content (#4384)

In _prepare_message_for_openai(), the text_reasoning case unconditionally
accessed all_messages[-1] to attach reasoning_details. When a reasoning
model (e.g. gpt-5-mini) returns reasoning_details without text content,
all_messages is empty, causing an IndexError.

Guard the access by initializing all_messages with the current args dict
when it is empty, so reasoning_details can be safely attached.

* Address review: buffer reasoning details for valid message payloads (#4384)

- Buffer pending reasoning details and attach to the next message with

- When reasoning is the only content, emit a message with empty content
  to satisfy Chat Completions schema requirements.
- Strengthen test assertions to verify text+reasoning co-location and
  that all messages with reasoning_details also have content or tool_calls.

  content consumed it
- Assert exact content values (content == '' not in ('', None))
- Assert exact list lengths (== 1 not >= 1) for stronger regression guards
- Add test for reasoning before FunctionCallContent

Moving yield inside `with _framework_event_origin()` blocks in the

Windows. The token stays un-reset while the generator is suspended,
and async generator finalization in a different contextvars.Context
triggers ValueError, corrupting OpenTelemetry span state and causing
test_span_creation_and_attributes to see leaked spans.

Keep yields outside the context manager blocks to ensure tokens are
reset immediately before the generator suspends.

Python: fix(python): Handle thread.message.completed event in Assistants API streaming (#4333 )

* fix: handle thread.message.completed event in Assistants API streaming

Previously, `thread.message.completed` events fell through to the
catch-all `else` branch and yielded empty `ChatResponseUpdate` objects,
silently discarding fully-resolved annotation data (file citations,
file paths, and their character-offset regions).

This commit adds a dedicated handler for `thread.message.completed`
that:
- Walks the completed ThreadMessage.content array
- Extracts text blocks with their fully-resolved annotations
- Maps FileCitationAnnotation and FilePathAnnotation to the
  framework's Annotation type with proper TextSpanRegion data
- Yields a ChatResponseUpdate containing the complete text and
  annotations

Fixes #4322

* test: add tests for thread.message.completed annotation handling

Tests cover:
- File citation annotation extraction
- File path annotation extraction
- Multiple annotations on a single text block
- Text-only messages (no annotations)
- Non-text blocks are skipped
- Mixed content blocks (text + image)
- Conversation ID propagation

* fix: address Copilot review - add quote field and log unrecognized annotations

- Include `quote` from `annotation.file_citation.quote` in
  `additional_properties` for FileCitationAnnotation, preserving the
  exact cited text snippet from the source file
- Add `else` clause to log unrecognized annotation types at debug level,
  consistent with the pattern in `_responses_client.py`
- Add `import logging` and module-level logger

* test: add coverage for quote field and unrecognized annotation logging

- test_message_completed_with_file_citation_quote: verifies quote is
  included in additional_properties
- test_message_completed_with_file_citation_no_quote: verifies quote
  is omitted when None
- test_message_completed_unrecognized_annotation_logged: verifies
  unknown annotation types are logged at debug level and skipped

* fix: address reviewer nits — logger name convention + annotation type string

Per @giles17's review:
- Use logging.getLogger('agent_framework.openai') to match module convention
- Simplify debug message to use annotation.type instead of type().__name__

* refactor: move message.completed tests into consolidated test file

Per @giles17's review: moved all tests from test_assistants_message_completed.py
into test_openai_assistants_client.py and deleted the standalone file.

* fix: resolve mypy no-redef and ruff RET504 lint errors

- Remove duplicate type annotation for 'ann' variable (no-redef)
- Return directly from fixture instead of unnecessary assignment (RET504)

* fix: rename annotation variable in completed block to fix mypy type conflict

The 'annotation' loop variable in thread.message.completed has type
FileCitationAnnotation | FilePathAnnotation, which conflicts with the
delta block's 'annotation' of type FileCitationDeltaAnnotation |
FilePathDeltaAnnotation. Renamed to 'completed_annotation' to avoid
mypy 'Incompatible types in assignment' error.

* fix: remove quote field from FileCitationAnnotation handling

Python: fix(python): Use AgentResponse.value instead of model_validate_json in HITL sample (#4405 )

* fix(python): use AgentResponse.value instead of model_validate_json in HITL sample

Since the agent is configured with response_format=GuessOutput, the
AgentResponse already provides .value with the parsed Pydantic model.
Using .value is more idiomatic and avoids redundant JSON parsing.

Fixes #4396

* fix: add safety guard for AgentResponse.value being None

Address Copilot review feedback: .value is optional and may be None
if response_format isn't propagated through the streaming path.
Add an explicit None check with a clear error message.

.NET: AzureAI Package - Skip tool validation when UseProvidedChatClientAsIs is true (#4389 )

* Skip tool validation when UseProvidedChatClientAsIs is true (#3855)

When GetAIAgentAsync is called with ChatClientAgentOptions.UseProvidedChatClientAsIs = true,
skip requireInvocableTools validation so users can handle function calls manually
via custom ChatClient middleware without needing to provide matching AIFunction tools.

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

* Simplify requireInvocableTools expression per review feedback

UseProvidedChatClientAsIs is a non-nullable bool, so use ! operator
instead of != true for clarity.

* Decouple tool matching from validation and add tool preservation test (#3855)

Always match provided AIFunctions to server-side function definitions
regardless of requireInvocableTools flag. Only throw when validation
is required and no match is found. This ensures UseProvidedChatClientAsIs
still preserves user-provided AIFunction tools instead of falling back
to the broken ResponseToolAITool wrapper.

   as Mermaid node identifiers. Raw IDs containing spaces, dots, or
   non-ASCII characters (e.g. Japanese) caused Mermaid parse errors.

2. Fix conditional edge arrow syntax from '.--> ' (invalid) to '.-> '
   (valid Mermaid dotted arrow syntax).

Fixes #1406

* Use recognizable sanitized IDs for Mermaid node identifiers\n\nReplace generic node_0/node_1 aliases with IDs derived from the original\nexecutor names. ASCII letters, digits, and underscores are preserved;\nother characters become underscores (collapsed, trimmed). Leading digits\nget an n_ prefix. Collisions are resolved with a numeric suffix.\n\nThis keeps node IDs readable in the Mermaid source while the display\nlabels continue to show the full original names."

* Remove issue number references from test names and comments"

* Address PR review feedback from Copilot\n\n- Add Throw.IfNull(id) guard to SanitizeMermaidNodeId\n- Add safety limit (10,000) to collision resolution loop\n- Restore missing edge assertions (middle1/middle2 --> end)\n- Fix comment to show actual sanitized ID (n_1_User_input)\n- Use stricter regex in Unicode test (must start with letter/underscore)"

* Address second round of PR review feedback\n\n- Escape node display labels via EscapeMermaidLabel to handle quotes,\n  brackets, and newlines in executor IDs\n- Fix XML doc on SanitizeMermaidNodeId to accurately describe that\n  existing consecutive underscores in input are preserved\n- Restore specific edge assertion (mid --> end) in conditional edge test\n- Restore fan-in routing assertions (s1/s2 through intermediate node,\n  no direct edges to t) in fan-in test"

Python: Fix walrus operator precedence for model_id kwarg in AzureOpenAIResponsesClient (#4310 )

* Fix walrus operator precedence for model_id in AzureOpenAIResponsesClient (#4299)

Add parentheses around the walrus assignment so model_id receives the
actual string value instead of the boolean result of
`kwargs.pop(...) and not deployment_name`.

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

* Address review: replace walrus with explicit None check, add edge-case tests (#4299)

- Replace walrus operator with explicit assignment and 'is not None'
  check to avoid boolean-coercion pitfalls (empty string now correctly
  surfaces as ValueError instead of silently falling back)
- Add test: deployment_name takes precedence over model_id kwarg
- Add test: model_id='' raises ValueError
- Add test: model_id=None falls back to env var

* Add explicit validation for empty model_id in AzureOpenAIResponsesClient

Reject empty or whitespace-only model_id with ValueError instead of

defined in production code rather than relying on downstream validation.

Python: Fix executor handler type resolution when using from __future__ import annotations (#4317 )

* Python: Fix Executor handler type checking with __future__ annotations (#3898)

Use typing.get_type_hints() in _validate_handler_signature to resolve
string annotations from `from __future__ import annotations`. This
mirrors the fix applied to FunctionExecutor in #2308.

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

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

* Address PR review feedback for #3898: improve error handling and test coverage

- Wrap typing.get_type_hints() in try/except to provide a descriptive
  ValueError mentioning the handler name when annotations cannot be resolved
- Strengthen bare context test to assert output_types and workflow_output_types
- Add test for @handler(input=..., output=...) with future annotations

* Fix #3898: fall back to raw annotations when get_type_hints fails

When typing.get_type_hints(func) raises NameError (unresolvable forward
ref), AttributeError, RecursionError, or any other exception, fall back
to the raw parameter annotations instead of raising a ValueError.
This matches the suggestion from @moonbox3 on PR #4317.

Python: Fix agent option merge to support dict-defined tools (#4314 )

* Fix _merge_options dropping dict-defined tools (#4303)

_merge_options used getattr(tool, 'name', None) to de-duplicate tools,
which returns None for dict-style tool definitions. This caused all
override dict tools to be treated as duplicates of each other and of any
base dict tools, silently dropping them.

Add _get_tool_name() helper that extracts the name from both object-style
tools (via .name attribute) and dict-style tools (via tool['function']['name']).

Python: Fix WorkflowAgent not persisting response messages to session history (#1694 ) (#4319 )

WorkflowAgent._run_impl() and _run_stream_impl() did not set
session_context._response before calling _run_after_providers().
This caused InMemoryHistoryProvider.after_run() to see context.response
as None, so response messages were never stored in the session.

On subsequent runs, the workflow only received prior user inputs without
assistant responses, breaking multi-turn conversations.

Fix: Set session_context._response to the workflow result before running
after_run providers, matching the behavior of the regular Agent class.

Python: Preserve workflow run kwargs when continuing with run(responses=...) (#4296 )

* fix(python): preserve workflow run kwargs on response continuation (#4293)

When continuing a paused workflow with run(responses=...), the existing
run kwargs stored in state were unconditionally overwritten with an empty
dict. This caused subsequent agent invocations to lose the original run
context (e.g., custom_data, user tokens).

Now kwargs are only overwritten when:
- New kwargs are explicitly provided (override), or
- State was just cleared for a fresh run (initialize to {})

On continuation without new kwargs, existing kwargs are preserved.

  verify the is-not-None boundary between overwrite and preserve
- Add test for reset_context=True with no kwargs to exercise the elif
  branch that initializes WORKFLOW_RUN_KWARGS_KEY to {}
- Add len assertion to override test for consistency

.NET: Fixing issue where OpenTelemetry span is never exported in .NET in-process workflow execution (#4196 )

* 1. Add reproduction test for issue #4155: workflow.run Activity never stopped in streaming OffThread path

The WorkflowRunActivity_IsStopped_Streaming_OffThread test demonstrates that
the workflow.run OpenTelemetry Activity created in StreamingRunEventStream.RunLoopAsync
is started but never stopped when using the OffThread/Default streaming execution.
The background run loop keeps running after event consumption completes, so the
using Activity? declaration never disposes until explicit StopAsync() is called.

2. Fix workflow.run Activity never stopped in streaming OffThread execution (#4155)

The workflow.run OpenTelemetry Activity in StreamingRunEventStream.RunLoopAsync
was scoped to the method lifetime via 'using'. Since the run loop only exits on
cancellation, the Activity was never stopped/exported until explicit disposal.

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

* Add root-level workflow.session activity spanning run loop lifetime\n\nImplements two-level telemetry hierarchy per PR feedback from lokitoth:\n- workflow.session: spans the entire run loop / stream lifetime\n- workflow_invoke: per input-to-halt cycle, nested within the session\n\nThis ensures the session activity stays open across multiple turns,\nwhile individual run activities are created and disposed per cycle.\n\nAlso fixes linkedSource CancellationTokenSource disposal leak in\nStreamingRunEventStream (added using declaration)."

* Address Copilot review: fix Activity/CTS disposal, rename activity, add error tag\n\n1. LockstepRunEventStream: Remove 'using' from Activity in async iterator\n   and manually dispose in finally block (fixes #4155 pattern). Also dispose\n   linkedSource CTS in finally to prevent leak.\n2. Tags.cs: Add ErrorMessage (\"error.message\") tag for runtime errors,\n   distinct from BuildErrorMessage (\"build.error.message\").\n3. ActivityNames: Rename WorkflowRun from \"workflow_invoke\" to \"workflow.run\"\n   for cross-language consistency.\n4. WorkflowTelemetryContext: Fix XML doc to say \"outer/parent span\" instead\n   of \"root-level span\".\n5. ObservabilityTests: Assert WorkflowSession absence when DisableWorkflowRun\n   is true.\n6. WorkflowRunActivityStopTests: Fix streaming test race by disposing\n   StreamingRun before asserting activities are stopped.\n7. StreamingRunEventStream/LockstepRunEventStream: Use Tags.ErrorMessage\n   instead of Tags.BuildErrorMessage for runtime error events."

* Review fixes: revert workflow_invoke rename, use 'using' for linkedSource, move SessionStarted earlier\n\n- Revert ActivityNames.WorkflowRun back to \"workflow_invoke\" (OTEL semantic convention contract)\n- Use 'using' declaration for linkedSource CTS in LockstepRunEventStream (no timing sensitivity)\n- Move SessionStarted event before WaitForInputAsync in StreamingRunEventStream to match Lockstep behavior"

* Improve naming and comments in WorkflowRunActivityStopTests"

* Prevent session Activity.Current leak in lockstep mode, add nesting test

Save and restore Activity.Current in LockstepRunEventStream.Start() so the
session activity doesn't leak into caller code via AsyncLocal. Re-establish
Activity.Current = sessionActivity before creating the run activity in
TakeEventStreamAsync to preserve parent-child nesting.

Add test verifying app activities after RunAsync are not parented under the
session, and that the workflow_invoke activity nests under the session."

* Fix stale XML doc: WorkflowRun -> WorkflowInvoke in ObservabilityTests
