  • Python: Bump versions for a release. Update CHANGELOG (#5385)
    * Bump versions for a release. Update CHANGELOG

  • Python: Expose forwardedProps to agents and tools via session metadata (#5264)
    * Expose forwarded_props to agents and tools via session metadata (#5239)
    
    Include forwarded_props from AG-UI request input_data in session.metadata
    (agent runner) and function_invocation_kwargs (workflow runner) so that
    agents, tools, and workflow executors can access request-level metadata
    such as invocation source flags from CopilotKit.
    
    - Add forwarded_props to base_metadata in _agent_run.py when present
    - Add 'forwarded_props' to AG_UI_INTERNAL_METADATA_KEYS to filter it
      from LLM-bound client metadata
    - Extract forwarded_props in _workflow_run.py and pass via
      function_invocation_kwargs to workflow.run()
    - Accept both snake_case and camelCase keys (forwarded_props/forwardedProps)

    * fix(ag-ui): pass stream=True as literal to satisfy pyright overload resolution (#5239)
    
    The previous fix passed stream=True via **kwargs dict, which prevented
    pyright from resolving the Workflow.run() overload to the streaming
    variant. Pass stream=True as an explicit keyword argument so pyright
    can correctly infer the ResponseStream return type.
    
    Also remove unused pytest import in test file.

    * fix: address PR review feedback for forwarded_props (#5239)
    
    - Use key-presence checks instead of truthiness for forwarded_props so
      empty dict {} is forwarded correctly
    - Gate function_invocation_kwargs on workflow.run() signature inspection
      to avoid TypeError for workflows without **kwargs
    - Change _build_safe_metadata to drop (with warning) keys whose
      serialized values exceed 512 chars instead of truncating into invalid
      JSON
    - Rewrite metadata tests to exercise _build_safe_metadata directly with
      JSON-decodability and truncation assertions
    - Add workflow tests for empty dict forwarded_props, stream=True
      assertion, and signature-gated kwarg dropping

  • Python: AG-UI deterministic state updates from tool results (#5201)
    * AG-UI deterministic state updates from tool results
    
    * fix(ag-ui): address PR #5201 review comments
    
    1. Add missing AGUIEventConverter, AGUIHttpService, __version__ to
       _IMPORTS in core ag_ui lazy-export list to match the .pyi stub.
    
    2. Coalesce predictive and deterministic state snapshots into a single
       StateSnapshotEvent when both mechanisms are active on the same tool
       result, reducing redundant snapshot traffic.
    
    3. Update state_update() docstring to clarify that a predictive snapshot
       may be emitted before the deterministic one when predict_state_config
       is active.

  • Python: Stop emitting duplicate reasoning content from OpenAI response.reasoning_text.done and response.reasoning_summary_text.done events (#5162)
    * Fix reasoning text done events duplicating streamed delta content (#5157)
    
    The OpenAI Responses API sends both reasoning_text.delta (incremental
    chunks) and reasoning_text.done (full accumulated text) events. The
    chat client was emitting Content for both, causing ag-ui to append the
    full done text onto already-accumulated delta text, producing
    duplicated reasoning output.
    
    Stop emitting Content for reasoning_text.done and
    reasoning_summary_text.done events, matching how output_text.done is
    already handled (not emitted). The deltas contain all the content;
    the done event is redundant.

    * fix(openai): emit reasoning done content as fallback when no deltas observed (#5157)
    
    Address PR review feedback:
    - Track item_ids that received reasoning deltas via seen_reasoning_delta_item_ids set
    - Emit content from done events only when no deltas were received for the
      item_id, preventing silent content loss on stream resumption
    - Add comment documenting code_interpreter done event asymmetry
    - Replace redundant ag-ui test with deduplication-focused test
    - Add integration test for delta+done sequence in OpenAI chat client tests
    - Add fallback path tests for done events without preceding deltas

    * Address review feedback for #5157: Python: [Bug]: "type": "response.reasoning_text.delta" and "response.reasoning_text.done" both get exposed as "text_reasoning"
    
    * Fix AG-UI reasoning streaming to use proper Start/End pattern (#5157)
    
    _emit_text_reasoning now follows the same streaming pattern as _emit_text:
    - Emits ReasoningStartEvent/ReasoningMessageStartEvent only on the first
      delta for a given message_id
    - Emits only ReasoningMessageContentEvent for subsequent deltas
    - Defers ReasoningMessageEndEvent/ReasoningEndEvent until
      _close_reasoning_block is called (on content type switch or end-of-run)
    
    This produces the correct protocol pattern:
      ReasoningStartEvent
        ReasoningMessageStartEvent
        ReasoningMessageContentEvent(delta1)
        ReasoningMessageContentEvent(delta2)
        ReasoningMessageEndEvent
      ReasoningEndEvent
    
    Instead of wrapping every delta in a full Start→End sequence.
    
    Backward compatibility is preserved: calling _emit_text_reasoning without
    a flow argument still produces the full sequence per call.

    * Fix import ordering lint error in AG-UI test file (#5157)

    * Fix mypy error: rename loop variable to avoid type conflict with WorkflowEvent
    
    The 'event' variable was already typed as WorkflowEvent[Any] from the
    async for loop at line 590. Reusing it in the _close_reasoning_block
    loop (which returns list[BaseEvent]) caused an incompatible assignment
    error. Renamed to 'reasoning_evt' to avoid the conflict.

  • Python: Update Python Packages for rc6 (#4979)
    * python package update
    
    * small fix
  • 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

    - 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: 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

    * 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.

      _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

    Change flow.interrupts assignment to append so that all interrupt entries
    accumulate when multiple tools require approval in a single turn.
    
    Both _run_common.py and _agent_run.py used assignment (=) which caused
    each new interrupt to overwrite the previous one. Switching to append()

  • Python: Fix _deduplicate_messages catch-all branch dropping valid repeated messages (#4716)
    * Fix _deduplicate_messages catch-all branch dropping valid repeated messages (#4682)
    
    Remove the catch-all dedup branch that used (role, hash(content_str)) as a
    dedup key. This incorrectly treated any two messages with the same role and
    identical content as duplicates, dropping valid repeated messages (e.g., a
    user saying 'yes' to confirm two separate things).
    
    The tool-specific dedup branches (tool results by call_id, assistant tool
    calls by call_id tuple) remain unchanged as they correctly identify true
    protocol-level duplicates.

    * Address review: consecutive-duplicate detection for non-tool messages (#4682)
    
    - Replace blanket dedup removal with consecutive-duplicate detection:
      only skip a message if the immediately preceding message has the same
      role and content, preserving protection against upstream replays while
      allowing identical messages at different conversation points.
    - Strengthen test assertions to verify message identity and order, not
      just list length.
    - Add tests for consecutive duplicate skipping, non-consecutive
      preservation, and messages with contents=None.

    * Apply pre-commit auto-fixes
    
    * Use message_id for deduplication instead of content hashing
    
    Deduplicate general messages by message_id when available, replacing
    the consecutive-duplicate content check. Two messages with the same id
    are definitively the same message (upstream replay), while identical
    content with distinct ids (e.g. repeated "yes" confirmations) is
    preserved. Messages without a message_id are always kept.
    
    * Fix message_id dedup: truthy check, content-hash fallback, log safety
    
    - Use truthy check (`if msg.message_id`) instead of `is not None` so
      empty-string IDs fall through to content-hash dedup rather than
      collapsing unrelated messages.
    - Add content-hash fallback for messages without message_id, preventing
      false negatives from integrations that don't set IDs.
    - Remove raw message_id from log format string (addresses log-injection
      surface with control characters).
    - Add tests for empty-string message_id edge cases.
    - Update existing tests to reflect content-hash dedup behavior.

  • [BREAKING] Python: clean up kwargs across agents, chat clients, tools, and sessions (#4581)
    * Python: clean up kwargs across agents, chat clients, tools, and sessions (#3642)
    
    Audit and refactor public **kwargs usage across core agents, chat clients,
    tools, sessions, and provider packages per the migration strategy codified
    in CODING_STANDARD.md.
    
    Key changes:
    - Add explicit runtime buckets: function_invocation_kwargs and client_kwargs
      on RawAgent.run() and chat client get_response() layers.
    - Refactor FunctionTool to prefer explicit ctx: FunctionInvocationContext
      injection; legacy **kwargs tools still work via _forward_runtime_kwargs.
    - Refactor Agent.as_tool() to use direct JSON schema, always-streaming
      wrapper, approval_mode parameter, and UserInputRequiredException
      propagation (integrates PR #4568 behavior).
    - Remove implicit session bleeding into FunctionInvocationContext; tools
      that need a session must receive it via function_invocation_kwargs.
    - Lower chat-client layers after FunctionInvocationLayer accept only
      compatibility **kwargs (client_kwargs flattened, function_invocation_kwargs
      ignored).
    - Add layered docstring composition from Raw... implementations via
      _docstrings.py helper.
    - Clean up provider constructors to use explicit additional_properties.
    - Deprecation warnings on legacy direct kwargs paths.
    - Update samples, tests, and typing across all 23 packages.
    
    Resolves #3642

  • Python: Fix function_approval_response extraction in AG-UI workflow path (#4550)
    * Extract function_approval_response from workflow messages (#4546)
    
    _extract_responses_from_messages now handles function_approval_response
    content in addition to function_result content. Previously, approval
    responses sent via the messages field were silently dropped because the
    function only checked for content.type == "function_result".
    
    The approval response is keyed by content.id and includes the approved
    status, id, and serialized function_call — consistent with how
    _coerce_content identifies approval response payloads.

  • Python: Fix: Parse oauth_consent_request events in Azure AI client (#4197)
    * Fix: Parse oauth_consent_request events in Azure AI client (#3950)
    
    When Azure AI Agent Service returns an oauth_consent_request output item
    for OAuth-protected MCP tools, the base OpenAI responses parser drops it
    (hits case _ default branch). This causes agent runs to complete silently
    with zero content.
    
    Changes:
    - Add oauth_consent_request ContentType and Content.from_oauth_consent_request()
      factory with consent_link field and user_input_request=True
    - Override _parse_response_from_openai and _parse_chunk_from_openai in
      RawAzureAIClient to intercept Azure-specific oauth_consent_request items
    - Add _emit_oauth_consent helper in AG-UI to emit CustomEvent for frontends
    - Add tests proving base parser drops the event and Azure AI override catches it

  • Python: Fix doubled tool_call arguments in MESSAGES_SNAPSHOT when streaming (#4200)
    * fix: prevent doubled tool_call arguments in MESSAGES_SNAPSHOT
    
    When streaming with client-side tools, some providers send a full-
    arguments replay after the streaming deltas complete. The `_emit_tool_call`
    function unconditionally appends every arguments delta to the internal
    `flow.tool_calls_by_id` tracking dictionary via `+=`. When the replay
    contains the exact same complete arguments string that was already
    accumulated from prior deltas, the arguments get doubled (e.g.,
    `{"todoText":"buy groceries"}{"todoText":"buy groceries"}`).
    
    This causes `MESSAGES_SNAPSHOT` events to contain invalid doubled JSON in
    `tool_calls[].function.arguments`, breaking any client or middleware that
    relies on snapshots for state reconstruction.
    
    The fix adds a guard (mirroring the existing duplicate guard in
    `_emit_text`) that detects when the incoming delta exactly equals the
    already-accumulated arguments string, indicating a full-arguments replay
    rather than an incremental delta. In this case the append is skipped,
    preventing the doubling.
    
    The `ToolCallArgsEvent` deltas are still emitted correctly for real-time
    streaming — only the internal snapshot accumulator is guarded.
    
    Fixes #4194
    
    * fix: move duplicate check before event emission + add test
    
    Address Copilot review feedback:
    1. Move duplicate full-arguments replay detection BEFORE emitting
       ToolCallArgsEvent, for consistency with _emit_text() which returns
       early without emitting any events on replay detection.
    2. Add test_emit_tool_call_skips_duplicate_full_arguments_replay() to
       verify the duplicate detection behavior for tool call arguments,
       matching the existing test pattern for text content.

    remove the redundant --dist loadfile from all workflow files and

    * refactor: remove RUN_INTEGRATION_TESTS flag
    
    Integration test gating now uses two mechanisms:
    - `@pytest.mark.integration` for test selection via `-m` filtering
    - `skip_if_*_disabled` for credential/service availability checks
    
    The RUN_INTEGRATION_TESTS env var was redundant since the marker handles
    selection and the skip decorators already check for actual credentials.

  • Python: [BREAKING] Redesign Python exception hierarchy (#4082)
    * [BREAKING] Redesign Python exception hierarchy
    
    Replace the flat ServiceException family with domain-scoped branches:
    - AgentException (with InvalidAuth, InvalidRequest, InvalidResponse, ContentFilter)
    - ChatClientException (same consistent suberrors)
    - IntegrationException (same + InitializationError)
    - WorkflowException (Runner, Convergence, Checkpoint, Validation, Action, Declarative)
    - ContentError (AdditionItemMismatch)
    - ToolException / ToolExecutionException (unchanged)
    - MiddlewareException / MiddlewareTermination (unchanged)
    
    Key changes:
    - All Service* exceptions removed (ServiceException, ServiceInitializationError, etc.)
    - AgentExecutionException split into AgentInvalidRequest/ResponseException
    - AgentInvocationError removed, split into AgentInvalidRequest/ResponseException
    - Workflow exceptions moved from _workflows/_exceptions.py into main exceptions.py
    - _workflows/__init__.py emptied; main __init__.py imports directly from submodules
    - Purview exceptions re-parented under IntegrationException hierarchy
    - Init validation errors use built-in ValueError/TypeError instead of custom exceptions
    - CODING_STANDARD.md updated with hierarchy design and rationale
    
    Fixes microsoft/agent-framework#3410

  • Python: [BREAKING] Remove FunctionTool[Any] compatibility shim for schema passthrough (#3600) (#3907)
    * Fix #3600: Pass JSON schemas through without Pydantic conversion
    
    This change optimizes FunctionTool and MCP flows by passing JSON schemas
    directly to providers without converting them to Pydantic models first.
    
    Key changes:
    - Store JSON schema as-is when supplied to FunctionTool
    - Skip Pydantic model_validate for schema-supplied tools in invoke()
    - Return MCP tool schemas directly without conversion
    - Add comprehensive tests for schema passthrough behavior
    
    Performance benefits:
    - Eliminates expensive Pydantic model creation for supplied schemas
    - Preserves exact schema structure (additionalProperties, custom fields, etc.)
    - Reduces memory overhead and initialization time
    
    Maintains backward compatibility:
    - Function signature inference still uses Pydantic models
    - Explicit Pydantic models passed as input_model work as before
    - All existing tests pass
    
    * Fix schema passthrough validation and remove helper
    
    * Simplify FunctionTool without generic model dependency
    
    * Fix FunctionTool typing fallout in 3600
    
    * Remove FunctionTool[Any] compatibility shim
    
    * Use serializable kwargs in OTEL tool args

    - Replace ContextProvider with BaseContextProvider across all packages
    - Replace context_provider param with context_providers (Sequence)
    - Replace thread= with session= in run() signatures
    - Replace get_new_thread() with create_session()

    - Remove _notify_thread_of_new_messages from WorkflowAgent
    - Wire before_run/after_run context provider pipeline in RawAgent

    * fix: update all tests for context provider pipeline, fix lazy-loaders, remove old test files
    
    * refactor: update all sample files for context provider pipeline (AgentThread→AgentSession, ContextProvider→BaseContextProvider)
    
    * fix: update remaining ag-ui references (client docstring, getting_started sample)

    * refactor: merge context_providers and sessions sample folders into sessions, remove aggregate_context_provider
    
    * refactor: UserInfoMemory stores state in session.state instead of instance attributes
    
    * feat: add Pydantic BaseModel support to session state serialization
    
    Pydantic models stored in session.state are now automatically serialized
    via model_dump() and restored via model_validate() during to_dict()/from_dict()
    round-trips. Models are auto-registered on first serialization; use
    register_state_type() for cold-start deserialization.
    
    Also export register_state_type as a public API.
    
    * fix mem0
    
    * Update sample README links and descriptions for session terminology
    
    - Replace 'thread' with 'session' in sample descriptions across all READMEs
    - Update file links for renamed samples (mem0_sessions, redis_sessions, etc.)
    - Fix Threads section → Sessions section in main samples/README.md
    - Update tools, middleware, workflows, durabletask, azure_functions READMEs
    - Update architecture diagrams in concepts/tools/README.md
    - Update migration guides (autogen, semantic-kernel)
    
    * Fix broken Redis README link to renamed sample
    
    * Fix Mem0 OSS client search: pass scoping params as direct kwargs
    
    AsyncMemory (OSS) expects user_id/agent_id/run_id as direct kwargs,

    Adds tests for both client types.
    
    Port of fix from #3844 to new Mem0ContextProvider.
    
    * Fix rebase issues: restore missing _conversation_state.py and checkpoint decode logic
    
    - Add back _conversation_state.py (encode/decode_chat_messages) lost in rebase
    - Fix on_checkpoint_restore to decode cache/conversation with decode_chat_messages
    - Fix on_checkpoint_restore to use decode_checkpoint_value for pending requests
    - Add tests/workflow/__init__.py for relative import support
    - Fix test_agent_executor checkpoint selection (checkpoints[1] not superstep)
    
    * Add STORES_BY_DEFAULT ClassVar to skip redundant InMemoryHistoryProvider injection
    
    Chat clients that store history server-side by default (OpenAI Responses API,
    Azure AI Agent) now declare STORES_BY_DEFAULT = True. The agent checks this
    during auto-injection and skips InMemoryHistoryProvider unless the user
    explicitly sets store=False.

  • Python: Centralize tool result parsing in FunctionTool.invoke() (#3854)
    * Centralize tool result parsing in FunctionTool.invoke()
    
    - Add parse_result static method to FunctionTool that converts raw
      function return values to strings at invocation time
    - Add result_parser parameter to FunctionTool and @tool decorator
      for custom parsing
    - Remove prepare_function_call_results from all 9 consumer files
      and from the public API
    - Update MCPTool to parse MCP types directly to strings via
      _parse_tool_result_from_mcp and _parse_prompt_result_from_mcp
    - Change MCPTool parse_tool_results/parse_prompt_results type from
      Literal[True] | Callable | None to Callable | None
    - Remove ReturnT type parameter from FunctionTool (now single
      generic ArgsT since invoke() always returns str)
    - Update all subclass signatures and docstrings
    
    Fixes #1147
    
    * Fix test_mcp_tool_call_tool_with_meta_integration for string results
    
    The test was still accessing result[0].additional_properties but
    invoke() now returns a string, not a list of Content objects.
    
    * Fix SIM108 lint: use binary operator for output assignment
    
    * Fix bedrock: use FunctionTool.parse_result instead of str() fallback
    
    str(result) turns None into literal 'None' and dicts into Python reprs
    with single quotes, breaking JSON parsing. Use the shared parse_result
    which handles None as '' and serializes via json.dumps.

    - Update all hook versions to latest (pre-commit-hooks v6, pyupgrade v3.21.2, bandit 1.9.3, uv-pre-commit 0.10.0)
    - Add PEP 723 inline script metadata to 34 samples with external deps
    - Remove autogen-agentchat/autogen-ext from dev deps (now declared per-sample)
    - Remove unused dev deps: pytest-env, tomli-w
    - Add agent-framework-core>=1.0.0b260130 lower bound to all 21 packages
    - Update CI workflow to use j178/prek-action
    - Update docs: DEV_SETUP.md, AGENTS.md, CODING_STANDARD.md, SAMPLE_GUIDELINES.md
    
    * updated lock
    
    * python: fix prek config paths for local execution and CI workflow
    
    Remove global 'files: ^python/' filter and strip python/ prefix from all path patterns in .pre-commit-config.yaml so prek finds files when run from the python/ directory. Update CI workflow to use --cd python instead of --config path. Include trailing whitespace fixes and dev dependency cleanup.
    
    * python: move helper scripts to scripts/ folder and exclude from checks
    
    * python: exclude AGENTS.md from prek markdown code lint
    
    * python: exclude AGENTS.md and azure_ai_search sample from markdown lint
    
    * fix m365 sample
    
    * python: ignore CPY rule for samples with PEP 723 headers
    
    * fix in dev_setup
    
    * python: replace aiofiles with regular open in samples
    
    * python: suppress reportUnusedImport in markdown code block checker
    
    * python: use samples pyright config for markdown code block checker
    
    Write a temp pyrightconfig.json matching pyrightconfig.samples.json rules (typeCheckingMode=off, only reportMissingImports and reportAttributeAccessIssue). Filter output to only fail on these rules since syntax-level errors (top-level await, undefined vars) are expected in README documentation snippets.
    
    * python: use markdown-code-lint with fixed globs instead of prek file list
    
    The prek-markdown-code-lint task received all changed files including non-README markdown and files with pre-existing broken imports. Replace with the standard markdown-code-lint task which uses the correct glob patterns (README.md, packages/**/README.md, samples/**/*.md).
    
    * python: exclude READMEs with pre-existing broken imports from markdown lint
    
    * python: fix broken README code snippets instead of excluding them
    
    - ag-ui: replace TextContent (removed) with content.type == 'text'
    - durabletask: fix import path to durabletask.worker.TaskHubGrpcWorker
    - orchestrations: use constructor params instead of .participants() method
    - observability: mark deprecated code blocks as plain text, filter
      reportMissingImports to agent_framework modules only
    - remove README excludes from markdown-code-lint task
    
    * add revision to gaia download
    
    * feat(python): parallelize checks across packages
    
    Run (package × task) cross-product in parallel using ThreadPoolExecutor
    and subprocesses. Key changes:
    
    - Add scripts/task_runner.py with shared parallel execution engine
    - Update run_tasks_in_packages_if_exists.py to accept multiple tasks
    - Update run_tasks_in_changed_packages.py with --files flag and parallel support
    - Add check-packages poe task (fmt+lint+pyright+mypy in parallel)
    - Add prek-markdown-code-lint and prek-samples-check with change detection
    - Split CI code quality workflow into parallel prek and mypy jobs
    - Update DEV_SETUP.md to document new parallel behavior
    
    Core package changes still trigger checks on all packages.
    
    * feat(ci): split code quality into 4 parallel jobs
    
    Split the single prek job into parallel jobs:
    - pre-commit-hooks: lightweight hooks (SKIP=poe-check)
    - package-checks: fmt/lint/pyright/mypy via check-packages
    - samples-markdown: samples-lint, samples-syntax, markdown-code-lint
    - mypy: change-detected mypy checks
    
    All 4 jobs run concurrently (×2 Python versions = 8 runners).
    
    * feat(ci): use only Python 3.10 for code quality checks
    
    * refactor(python): add future annotations and remove quoted types
    
    Add `from __future__ import annotations` to 93 package files that
    used quoted string annotations, then run pyupgrade --py310-plus to
    remove the now-unnecessary quotes.

    - Added warning docstrings to Raw* classes about layer ordering
    - Updated README in samples/getting_started/agents/custom with layer docs
    - Added test for span ordering with function calling
    
    * Fix layer ordering: FunctionInvocationLayer before ChatTelemetryLayer
    
    This ensures each inner LLM call gets its own telemetry span, resulting in
    the correct span sequence: chat -> execute_tool -> chat
    
    Updated all production clients and test mocks to use correct ordering:
    - ChatMiddlewareLayer (first)
    - FunctionInvocationLayer (second)
    - ChatTelemetryLayer (third)
    - BaseChatClient/Raw...Client (fourth)

    * updates
    
    * Remove terminate flag from FunctionInvocationContext, use MiddlewareTermination instead
    
    - Remove terminate attribute from FunctionInvocationContext
    - Add result attribute to MiddlewareTermination to carry function results
    - FunctionMiddlewarePipeline.execute() now lets MiddlewareTermination propagate
    - _auto_invoke_function captures context.result in exception before re-raising
    - _try_execute_function_calls catches MiddlewareTermination and sets should_terminate
    - Fix handoff middleware to append to chat_client.function_middleware directly
    - Update tests to use raise MiddlewareTermination instead of context.terminate
    - Add middleware flow documentation in samples/concepts/tools/README.md
    - Fix ag-ui to use FunctionMiddlewarePipeline instead of removed create_function_middleware_pipeline
    
    * fix: remove references to removed terminate flag in purview tests, add type ignore
    
    * fix: move _test_utils.py from package to test folder
    
    * fix: call get_final_response() to trigger context provider notification in streaming test
    
    * fix: correct broken links in tools README
    
    * docs: clarify default middleware behavior in summary table
    
    * fix: ensure inner stream result hooks are called when using map()/from_awaitable()
    
    * Fix mypy type errors
    
    * Address PR review comments on observability.py
    
    - Remove TODO comment about unconsumed streams, add explanatory note instead
    - Remove redundant _close_span cleanup hook (already called in _finalize_stream)
    - Clarify behavior: cleanup hooks run after stream iteration, if stream is not
      consumed the span remains open until garbage collected
    
    * Remove gen_ai.client.operation.duration from span attributes
    
    Duration is a metrics-only attribute per OpenTelemetry semantic conventions.
    It should be recorded to the histogram but not set as a span attribute.
    
    * Remove duration from _get_response_attributes, pass directly to _capture_response
    
    Duration is a metrics-only attribute. It's now passed directly to _capture_response
    instead of being included in the attributes dict that gets set on the span.
    
    * Remove redundant _close_span cleanup hook in AgentTelemetryLayer
    
    _finalize_stream already calls _close_span() in its finally block,
    so adding it as a separate cleanup hook is redundant.
    
    * Use weakref.finalize to close span when stream is garbage collected
    
    If a user creates a streaming response but never consumes it, the cleanup
    hooks won't run. Now we register a weak reference finalizer that will close
    the span when the stream object is garbage collected, ensuring spans don't
    leak in this scenario.
    
    * Fix _get_finalizers_from_stream to use _result_hooks attribute
    
    Renamed function to _get_result_hooks_from_stream and fixed it to
    look for the _result_hooks attribute which is the correct name in
    ResponseStream class.
    
    * Add missing asyncio import in test_request_info_mixin.py
    
    * Fix leftover merge conflict marker in image_generation sample
    
    * Update integration tests
    
    * Fix integration tests: increase max_iterations from 1 to 2
    
    Tests with tool_choice options require at least 2 iterations:
    1. First iteration to get function call and execute the tool
    2. Second iteration to get the final text response
    
    With max_iterations=1, streaming tests would return early with only
    the function call/result but no final text content.
    
    * Fix duplicate function call error in conversation-based APIs
    
    When using conversation_id (for Responses/Assistants APIs), the server
    already has the function call message from the previous response. We
    should only send the new function result message, not all messages
    including the function call which would cause a duplicate ID error.
    
    Fix: When conversation_id is set, only send the last message (the tool
    result) instead of all response.messages.
    
    * Add regression test for conversation_id propagation between tool iterations
    
    Port test from PR #3664 with updates for new streaming API pattern.
    Tests that conversation_id is properly updated in options dict during
    function invocation loop iterations.
    
    * Fix tool_choice=required to return after tool execution
    
    When tool_choice is 'required', the user's intent is to force exactly one
    tool call. After the tool executes, return immediately with the function
    call and result - don't continue to call the model again.
    
    This fixes integration tests that were failing with empty text responses
    because with tool_choice=required, the model would keep returning function
    calls instead of text.
    
    Also adds regression tests for:
    - conversation_id propagation between tool iterations (from PR #3664)
    - tool_choice=required returns after tool execution
    
    * Document tool_choice behavior in tools README
    
    - Add table explaining tool_choice values (auto, none, required)
    - Explain why tool_choice=required returns immediately after tool execution
    - Add code example showing the difference between required and auto
    - Update flow diagram to show the early return path for tool_choice=required
    
    * Fix tool_choice=None behavior - don't default to 'auto'
    
    Remove the hardcoded default of 'auto' for tool_choice in ChatAgent init.
    When tool_choice is not specified (None), it will now not be sent to the
    API, allowing the API's default behavior to be used.
    
    Users who want tool_choice='auto' can still explicitly set it either in
    default_options or at runtime.
    
    Fixes #3585
    
    * Fix tool_choice=none should not remove tools
    
    In OpenAI Assistants client, tools were not being sent when
    tool_choice='none'. This was incorrect - tool_choice='none' means
    the model won't call tools, but tools should still be available
    in the request (they may be used later in the conversation).
    
    Fixes #3585
    
    * Add test for tool_choice=none preserving tools
    
    Adds a regression test to ensure that when tool_choice='none' is set but
    tools are provided, the tools are still sent to the API. This verifies
    the fix for #3585.
    
    * Fix tool_choice=none should not remove tools in all clients
    
    Apply the same fix to OpenAI Responses client and Azure AI client:
    - OpenAI Responses: Remove else block that popped tool_choice/parallel_tool_calls
    - Azure AI: Remove tool_choice != 'none' check when adding tools
    
    When tool_choice='none', the model won't call tools, but tools should
    still be sent to the API so they're available for future turns.
    
    Also update README to clarify tool_choice=required supports multiple tools.
    
    Fixes #3585
    
    * Keep tool_choice even when tools is None
    
    Move tool_choice processing outside of the 'if tools' block in OpenAI
    Responses client so tool_choice is sent to the API even when no tools
    are provided.
    
    * Update test to match new parallel_tool_calls behavior
    
    Changed test_prepare_options_removes_parallel_tool_calls_when_no_tools to
    test_prepare_options_preserves_parallel_tool_calls_when_no_tools to reflect
    that parallel_tool_calls is now preserved even when no tools are present,
    consistent with the tool_choice behavior.
    
    * Fix ChatMessage API and Role enum usage after rebase
    
    - Update ChatMessage instantiation to use keyword args (role=, text=, contents=)
    - Fix Role enum comparisons to use .value for string comparison
    - Add created_at to AgentResponse in error handling
    - Fix AgentResponse.from_updates -> from_agent_run_response_updates
    - Fix DurableAgentStateMessage.from_chat_message to convert Role enum to string

    * Fix additional ChatMessage API and method name changes
    
    - Fix ChatMessage usage in workflow files (use text= instead of contents= for strings)
    - Fix AgentResponse.from_updates -> from_agent_run_response_updates in workflow files
    - Fix test files for ChatMessage and Role enum usage
    
    * Fix remaining ChatMessage API usage in test files
    
    * Fix more ChatMessage and Role API changes in source and test files
    
    - Fix ChatMessage in _magentic.py replan method
    - Fix Role enum comparison in test assertions
    - Fix remaining test files with old ChatMessage syntax
    
    * Fix ChatMessage and Role API changes across packages
    
    - Add Role import where missing
    - Fix ChatMessage signature: positional args to keyword args (role=, text=, contents=)
    - Fix Role enum comparisons: .role.value instead of .role string
    - Fix FinishReason enum usage in ag-ui event converters
    - Rename AgentResponse.from_updates to from_agent_run_response_updates in ag-ui
    
    Fixes API compatibility after Types API Review improvements merge
    
    * Fix ChatMessage and Role API changes in github_copilot tests
    
    * Fix ChatMessage and Role API changes in redis and github_copilot packages
    
    - Fix redis provider: Role enum comparison using .value
    - Fix redis tests: ChatMessage signature and Role comparisons
    - Fix github_copilot tests: ChatMessage signature and Role comparisons
    - Update docstring examples in redis chat message store

    - Fix conversations: Role enum to string conversion in two places
    - Fix tests: ChatMessage signatures and Role comparisons
    
    * Fix ChatMessage and Role API changes in a2a and lab packages
    
    - Fix a2a tests: Role comparisons and ChatMessage signatures
    - Fix lab tau2 source: Role enum comparison in flip_messages, log_messages, sliding_window
    - Fix lab tau2 tests: ChatMessage signatures and Role comparisons
    
    * Remove duplicate test files from ag-ui/tests (tests are in ag_ui_tests)
    
    * Fix ChatMessage and Role API changes across packages
    
    After rebasing on upstream/main which merged PR #3647 (Types API Review
    improvements), fix all packages to use the new API:
    
    - ChatMessage: Use keyword args (role=, text=, contents=) instead of
      positional args
    - Role: Compare using .value attribute since it's now an enum
    
    Packages fixed:
    - ag-ui: Fixed Role value extraction bugs in _message_adapters.py
    - anthropic: Fixed ChatMessage and Role comparisons in tests
    - azure-ai: Fixed Role comparison in _client.py
    - azure-ai-search: Fixed ChatMessage and Role in source/tests
    - bedrock: Fixed ChatMessage signatures in tests
    - chatkit: Fixed ChatMessage and Role in source/tests
    - copilotstudio: Fixed ChatMessage and Role in tests
    - declarative: Fixed ChatMessage in _executors_agents.py
    - mem0: Fixed ChatMessage and Role in source/tests
    - purview: Fixed ChatMessage in source/tests
    
    * Fix mypy errors for ChatMessage and Role API changes
    
    - durabletask: Use str() fallback in role value extraction
    - core: Fix ChatMessage in _orchestrator_helpers.py to use keyword args
    - core: Add type ignore for _conversation_state.py contents deserialization
    - ag-ui: Fix type ignore comments (call-overload instead of arg-type)
    - azure-ai-search: Fix get_role_value type hint to accept Any
    - lab: Move get_role_value to module level with Any type hint
    
    * Improve CI test timeout configuration
    
    - Increase job timeout from 10 to 15 minutes
    - Reduce per-test timeout to 60s (was 900s/300s)
    - Add --timeout_method thread for better timeout handling
    - Add --timeout-verbose to see which tests are slow
    - Reduce retries from 3 to 2 and delay from 10s to 5s
    
    This ensures individual test timeouts are shorter than the job
    timeout, providing better visibility when tests hang.
    
    With 60s timeout and 2 retries, worst case per test is ~180s.
    
    * Fix ChatMessage API usage in docstrings and source
    
    - Fix ChatMessage positional args in docstrings: _serialization.py, _threads.py, _middleware.py
    - Fix ChatMessage in tau2 runner.py
    - Fix role comparison in _orchestrator_helpers.py to use .value
    - Fix role comparison in _group_chat.py docstring example
    - Fix role assertions in test_durable_entities.py to use .value
    
    * Revert tool_choice/parallel_tool_calls changes - must be removed when no tools
    
    OpenAI API requires tool_choice and parallel_tool_calls to only be
    present when tools are specified. Restored the logic that removes
    these options when there are no tools.
    
    - Restored check in _chat_client.py to remove tool_choice and
      parallel_tool_calls when no tools present
    - Restored same logic in _responses_client.py
    - Reverted test to expect the correct behavior
    
    * fixed issue in tests
    
    * fix: resolve merge conflict markers in ag-ui tests
    
    * fix: restructure ag-ui tests and fix Role/FinishReason to use string types
    
    * fix: streaming function invocation and middleware termination
    
    - Refactor streaming function invocation to use get_final_response() on inner streams
    - Fix MiddlewareTermination to accept result parameter for passing results
    - Fix _AutoHandoffMiddleware to use MiddlewareTermination instead of context.terminate
    - Fix AgentMiddlewareLayer.run() to properly forward function/chat middleware
    - Remove duplicate middleware registration in AgentMiddlewareLayer.__init__
    - Fix exception handling in _auto_invoke_function to properly capture termination
    - Fix mypy errors in core package
    - Update tests to use stream=True parameter for unified run API
    
    * fix all tests command
    
    * Refactor integration tests to use pytest fixtures
    
    - Merge testutils.py into conftest.py for azurefunctions integration tests
    - Merge dt_testutils.py into conftest.py for durabletask integration tests
    - Convert all integration tests to use fixtures instead of direct imports
      (fixes ModuleNotFoundError with --import-mode=importlib)
    - Add sample_helper fixture for azurefunctions tests
    - Add agent_client_factory and orchestration_helper fixtures for durabletask
    - Integration tests now skip with descriptive messages when services unavailable
    - Restructure devui tests into tests/devui/ with proper conftest.py
    - Add test organization guidelines to CODING_STANDARD.md
    - Remove __init__.py from test directories per pytest best practices
    
    * Fix pytest_collection_modifyitems to only skip integration tests
    
    The hook was skipping all tests in the test session, not just
    integration tests. Now it only skips items in the integration_tests
    directory.
    
    * Fix mem0 tests failing on Python 3.13
    
    Use patch.object on the imported module instead of @patch with string
    path to ensure the mock takes effect regardless of import timing.
    
    * fix mem0
    
    * another attempt for mem0
    
    * fix for mem0
    
    * fix mem0
    
    * Increase worker initialization wait time in durabletask tests
    
    Increase from 2 to 8 seconds to allow time for:
    - Python startup and module imports
    - Azure OpenAI client creation
    - Agent registration with DTS worker
    - Worker connection to DTS
    
    This helps prevent test failures in CI where the first tests may run
    before the worker is fully ready to process requests.
    
    * Fix streaming test to use ResponseStream with finalizer
    
    The _consume_stream method now expects a ResponseStream that can provide
    a final AgentResponse via get_final_response(). Update the test to use
    ResponseStream with AgentResponse.from_updates as the finalizer.
    
    * Fix MockToolCallingAgent to use new ResponseStream API and update samples
    
    * small updates to run_stream to run
    
    * fix sub workflow
    
    * temp fix for az func test
