• Python: replace pre-commit with prek, add PEP 723 script deps, clean up dev dependencies (#3748)

  * python: replace pre-commit with prek, add PEP 723 script deps, clean up dev dependencies
  
  - Replace pre-commit with prek (Rust-native, faster pre-commit alternative)
  - Move supported hooks to repo: builtin for zero-clone speed
  - Add new builtin hooks: trailing-whitespace, check-merge-conflict, detect-private-key, check-added-large-files
  - 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.
  
  Fixes https://github.com/microsoft/agent-framework/issues/3578

  the correct span sequence: chat -> execute_tool -> chat
  
  Updated all production clients and test mocks to use correct ordering:
  - ChatMiddlewareLayer (first)
  - FunctionInvocationLayer (second)

  * 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.

  - 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
