.NET: feat: Implement return-to-previous routing in handoff workflow (#4356 )

* feat: Implement return-to-previous routing in handoff workflow

- Also obsoletes HandoffsWorkflowBuilder => HandoffWorkflowBuilder (no "s")

* refactor: Remove instance-shared current agent tracking in handoffs

Because the tracker was instance-shared between the start and end executors, it would be shared between all sessions, resulting in incorrect behaviour.

The corect way to do this is to keep the data in a shared executor scope, which is per-session.

* fix: Fix test logic for Handoff to correctly use checkpointing for multiturn

.NET: Add AsIChatClientWithStoredOutputDisabled for ProjectResponsesClient (#4911 )

* Add AsIChatClientWithStoredOutputDisabled for ProjectResponsesClient

Add extension method on ProjectResponsesClient in Microsoft.Agents.AI.AzureAI
package (Azure.AI.Extensions.OpenAI namespace) mirroring the existing extension
on ResponsesClient in the OpenAI package. This enables Azure AI consumers to
disable server-side response storage without depending on the OpenAI package.

- New ProjectResponsesClientExtensions class with AsIChatClientWithStoredOutputDisabled
- Optional deploymentName parameter (model is no longer required)
- Updated OpenAI counterpart doc to remove 'Required' wording for model param
- Added unit tests covering null guard, inner client accessibility,
  StoredOutputEnabled=false, and reasoning encrypted content inclusion/exclusion

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

* Preserve existing RawRepresentationFactory when disabling stored output

Python: Support structuredContent in MCP tool results and fix sampling options type (#4763 )

* Support MCP sampling tools capability (#4625)

Forward systemPrompt, tools, and toolChoice from MCP sampling requests
to the chat client's get_response() call. Also advertise the
sampling.tools capability to MCP servers when a client is configured.

- Pass SamplingCapability with tools support to ClientSession
- Convert systemPrompt to instructions in options
- Convert MCP Tool objects to FunctionTool instances for options
- Map MCP ToolChoice.mode to tool_choice in options
- Add tests for all new behaviors and update existing sampling tests

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

* Fix #4625: Support MCP sampling tool with proper typing and structured content

- Fix mypy error by typing sampling callback options as ChatOptions[None]
  instead of dict[str, Any], and importing ChatOptions from _types
- Handle structuredContent from CallToolResult in _parse_tool_result_from_mcp,
  serializing it as JSON text Content when present

  on non-JSON-serializable values instead of silently converting
- Add test for non-JSON-serializable structuredContent (TypeError)
- Add tests for empty systemPrompt ('') and empty tools list ([]) edge
  cases in sampling callback
- Expand TODO comment noting list[Content] return type constraint for
  future result_type support

* Address review feedback for #4625: move params to options, restore error info

- Remove stale TODO comment about response_format (ChatOptions already has it)
- Restore {ex} in sampling callback error message for useful debugging info
- Set structuredContent as additional_property on Content for structured access
- Move temperature, max_tokens, stop into options dict (not top-level kwargs)
- Only set temperature when provided (not all models support it)
- Add tests for generation params in options and temperature omission

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

* Fix MCP sampling callback and structured content error handling (#4625)

- Guard max_tokens like temperature: only set when not None, so options
  can properly evaluate to None when all params are absent
- Wrap json.dumps of structuredContent in try/except to fall back to
  str() for non-serializable values instead of propagating TypeError
- Extract test_connect_sampling_capabilities_with_client into its own
  test function so pytest can discover it independently
- Add test for max_tokens=None omission from options
- Update structured content non-serializable test to expect fallback

Python: Include reasoning messages in MESSAGES_SNAPSHOT events (#4844 )

* Include reasoning messages in MESSAGES_SNAPSHOT (#4843)

FlowState now tracks reasoning messages emitted during a run.
_emit_text_reasoning() persists reasoning (including encrypted_value)
into flow.reasoning_messages, and _build_messages_snapshot() appends
them to the final MESSAGES_SNAPSHOT event.

Changes:
- Add reasoning_messages field to FlowState
- Update _emit_text_reasoning() to accept optional flow parameter
- Include reasoning_messages in _build_messages_snapshot()
- Add 'reasoning' to ALLOWED_AGUI_ROLES so normalize_agui_role()
  preserves the role through snapshot round-trips
- Skip reasoning messages in agui_messages_to_agent_framework() since
  they are UI-only state and should not be forwarded to LLM providers
- Add regression tests for snapshot emission, encrypted value
  preservation, and multi-turn round-trip with reasoning

* Python: Include reasoning messages in MESSAGES_SNAPSHOT events

* Fix PR review feedback for reasoning persistence (#4843)

- Accumulate reasoning text per message_id (append deltas) instead of
  storing only the current chunk, matching flow.accumulated_text pattern
- Use camelCase encryptedValue in snapshot JSON to match AG-UI protocol
  conventions (toolCallId, encryptedValue)
- Normalize snake_case encrypted_value to encryptedValue in
  agui_messages_to_snapshot_format for input compatibility
- Update normalize_agui_role docstring to include reasoning role
- Add tests for incremental reasoning accumulation and key normalization

Python: Fix streaming path to emit mcp_server_tool_result on output_item.done instead of output_item.added (#4821 )

* Fix streaming path to deliver mcp_server_tool_result content (#4814)

Remove premature mcp_server_tool_result emission from the
response.output_item.added/mcp_call handler — at that point the MCP
server has not yet responded and output is always None.

Add a handler for response.mcp_call.completed that emits
mcp_server_tool_result with the actual tool output, matching the
non-streaming path behavior.

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

* Fix streaming path to deliver mcp_server_tool_result content (#4814)

Stop eagerly emitting mcp_server_tool_result on response.output_item.added
(when output is always None). Instead, handle response.output_item.done for
mcp_call items, which carries the full McpCall with populated output.

This matches the non-streaming path which guards with 'if item.output is not
None' before emitting the result.

- Add call_id fallback in response.output_item.done mcp_call handler to

- Use done_item instead of event for raw_representation to keep
  consistent with other output_item branches and non-streaming path
- Add test for call_id fallback when id attribute is missing
- Add raw_representation assertions to existing done handler tests

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

* Address review: call_id fallback for non-streaming path and test coverage (#4814)

- Add test for empty-string fallback when neither id nor call_id exist

Python: Fix A2AAgent to surface message content from in-progress TaskStatusUpdateEvents (#4798 )

* Fix A2AAgent dropping message content from in-progress TaskStatusUpdateEvents (#4783)

_updates_from_task() returned [] for working-state tasks when
background=False, silently discarding all intermediate message content
from task.status.message. Now extracts and yields message parts from
in-progress status updates during streaming.

Also fixed MockA2AClient.send_message to yield all queued responses
(enabling multi-event streaming tests) and added text parameter to
add_in_progress_task_response for tests that need status messages.

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

* Fix: gate intermediate status updates behind emit_intermediate flag and add missing test coverage

- Add emit_intermediate parameter to _updates_from_task and _map_a2a_stream
- Thread stream flag from run() so only streaming callers see intermediate updates
- Add IN_PROGRESS_TASK_STATES guard to emit_intermediate condition
- Add role parameter to test helper add_in_progress_task_response
- Add clarifying comment on MockA2AClient.send_message batch semantics
- Add tests for user role mapping, background precedence, non-streaming behavior,
  terminal task with no artifacts, and empty parts edge case

fix: FS Checkpoint storage special character support (#4730 )

The `sessionId`, an optional parameter when starting a new session when
running a workflow is an arbitrary string. This allows consumers to
support whatever ids are needed by other systems, but can result in
errors when an OS special or forbidden character is included.

The fix is to escape the paths, in a 1:1 manner. We rely on
EncodeDataString to do this.

.NET: Re-enable AzureAI.Persistent packaging and integration tests (#4769 ) (#4865 )

Azure.AI.Agents.Persistent 1.2.0-beta.10 now targets ME.AI 10.4.0+,
resolving the compatibility issue that required disabling this package.

- Remove IsPackable=false from the csproj
- Re-enable all 6 integration test classes (IntegrationDisabled → Integration)
- Remove outdated compatibility warning from README.md

Python: Fix PydanticSchemaGenerationError when using from __future__ import annotations with @tool (#4822 )

* Fix PydanticSchemaGenerationError with PEP 563 annotations in @tool

_resolve_input_model used raw param.annotation from inspect.signature(),
which returns string annotations when 'from __future__ import annotations'
is active (PEP 563). This caused Pydantic's create_model to fail for
complex types like Optional[int] or FunctionInvocationContext.

Use typing.get_type_hints() to resolve annotations to actual types before
passing them to create_model, matching the approach already used by
_discover_injected_parameters.

Fixes #4809

- Tools as list[FunctionTool] (including auto-extracted MCP tools)
- FoundryEvals provider with auto-detection of evaluator capabilities
- LocalEvaluator with @function_evaluator decorator for local checks

duplication. Now a new INNER_ACCUMULATED_USAGE context variable tracks
cumulative usage across all inner completions, and the agent span

Python: Emit TOOL_CALL_RESULT events when resuming after tool approval (#4758 )

* Emit TOOL_CALL_RESULT events on approval resume (#4589)

When a tool call is approved via the interrupt/resume flow,
_resolve_approval_responses executes the tool and injects the result
into the messages array, but no TOOL_CALL_RESULT SSE event was yielded
to the client.

Changes:
- _resolve_approval_responses now returns the list of resolved
  function_result Content objects instead of None
- run_agent_stream yields ToolCallResultEvent for each resolved
  approval result after RunStartedEvent is emitted
- Add ToolCallResultEvent to ag_ui.core imports in _agent_run.py

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

* Apply pre-commit auto-fixes

* fix(ag-ui): address PR review feedback for #4589

1. _resolve_approval_responses now returns only approved results (not
   rejections) so TOOL_CALL_RESULT events are emitted only for executed
   tools. Rejection results are still written into message history.

2. Emit resolved TOOL_CALL_RESULT events in the no-updates fallback
   RUN_STARTED path so approval results are never lost.

3. Rewrite tests to use real FunctionTool with func and
   approval_mode='always_require' via StubAgent default_options,
   verifying actual tool execution output in TOOL_CALL_RESULT content.
   Added test for rejection not emitting TOOL_CALL_RESULT.

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

* Fix #4589: clean up approval resolution and add missing tests

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

Python: Emit AG-UI events for MCP tool calls, results, and text reasoning (#4760 )

* Python: Emit AG-UI events for MCP tool calls, results, and text reasoning

Fixes #4213 — `_emit_content()` in the AG-UI layer only handled `text`,
`function_call`, `function_result`, `function_approval_request`, `usage`,
and `oauth_consent_request` content types. Foundry MCP content types
(`mcp_server_tool_call`, `mcp_server_tool_result`) and `text_reasoning`
fell through unhandled, producing no SSE events for AG-UI consumers.

Added three new handler functions wired into `_emit_content()`:

- `_emit_mcp_tool_call`: emits TOOL_CALL_START + TOOL_CALL_ARGS and
  tracks in FlowState for MESSAGES_SNAPSHOT inclusion
- `_emit_mcp_tool_result`: emits TOOL_CALL_END + TOOL_CALL_RESULT with
  full FlowState cleanup mirroring `_emit_tool_result`
- `_emit_text_reasoning`: emits the protocol-defined reasoning event
  sequence (ReasoningStart → MessageStart → MessageContent → MessageEnd
  → ReasoningEnd) with ReasoningEncryptedValueEvent for protected_data

* Add HTTP round-trip tests for MCP tool and reasoning SSE events

Exercises the full POST → SSE bytes → parse → validate pipeline for
mcp_server_tool_call, mcp_server_tool_result, text_reasoning, and
ReasoningEncryptedValueEvent content through FastAPI TestClient.

* Fix _emit_mcp_tool_result missing predictive_handler support (#4213)

- Add predictive_handler parameter to _emit_mcp_tool_result and mirror
  the apply_pending_updates + StateSnapshotEvent block from _emit_tool_result
- Forward predictive_handler from _emit_content to _emit_mcp_tool_result
- Add assertion for stored arguments in MCP tool call test
- Add test for predictive handler state snapshot after MCP tool result

Python: Support detail field in OpenAI Chat API image_url payload (#4756 )

* Support detail field in OpenAI image_url payload (#4616)

Include the optional 'detail' field from Content.additional_properties
when building image_url payloads for the OpenAI Chat API, matching the
existing pattern used for 'filename' in document file payloads.

* Apply pre-commit auto-fixes

* Remove reproduction report

* Simplify detail extraction from additional_properties (#4616)

- Remove unnecessary hasattr check; additional_properties is always
  initialized as a dict on Content instances.
- Use 'is not None' instead of truthy check to be more precise.

* Apply pre-commit auto-fixes

* Remove detail allowlist in chat client to align with responses client

Replace the strict allowlist check ('low', 'high', 'auto') with an
isinstance(detail, str) check so that any valid string detail value is
passed through to OpenAI. This aligns the chat client behavior with the
responses client, which passes detail through unconditionally.

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

Python: Fix MCP tool schema normalization for zero-argument tools missing 'properties' key (#4771 )

* Fix zero-argument MCP tool schema missing 'properties' key (#4540)

MCP servers for zero-argument tools (e.g. matlab-mcp-core-server's
detect_matlab_toolboxes) declare inputSchema as {"type": "object"}
without a "properties" key. OpenAI's API requires "properties" to
be present on object schemas, causing a 400 invalid_request_error.

Normalize inputSchema at MCP ingestion in load_tools() to inject an
empty "properties": {} when it is missing from object-type schemas.

* Address review feedback for #4540: improve test robustness and add defensive guard

- Look up loaded functions by name instead of index to avoid brittle
  ordering assumptions
- Add negative-path test cases: non-object schema (type: string) and
  empty schema ({}) to verify guard clause skips them correctly
- Assert original inputSchema dicts are not mutated by load_tools()
- Add defensive guard for tool.inputSchema being None

* Address review feedback for #4540: Python: [Bug]: Local stdio MCP works for calculator but fails for official matlab-mcp-core-server on LM Studio /v1/responses
