Python: add ag-ui tool result display channel (#5762)
* Python: add ag-ui tool result display channel Key decisions: - Add TOOL_RESULT_DISPLAY_KEY and make state_update accept optional state plus a tool_result display payload. - Keep text as the LLM-bound tool result while using the display marker only for ToolCallResultEvent.content. - Reuse one outer/inner Content additional_properties extraction helper for state and display markers, preserving fallback behavior when display is absent. Files changed: - python/packages/ag-ui/agent_framework_ag_ui/_state.py - python/packages/ag-ui/agent_framework_ag_ui/_run_common.py - python/packages/ag-ui/tests/ag_ui/test_run_common.py - python/packages/ag-ui/tests/ag_ui/golden/test_scenario_deterministic_state.py - python/issues/done/01-tool-result-display-channel.md Blockers/notes: - Slice 1 is complete and moved to issues/done. - Slice 2 remains for docstring and README documentation. * Python: document ag-ui tool result display channel Key decisions: - Document state_update as the single helper for LLM text, UI-only tool_result display content, and durable shared state. - Keep the display guidance explicit that text remains LLM-bound while tool_result feeds ToolCallResultEvent.content. - List both reserved additional_properties markers in the docstring return contract. Files changed: - python/packages/ag-ui/agent_framework_ag_ui/_state.py - python/packages/ag-ui/README.md - python/issues/done/02-docs-tool-result-display.md Blockers/notes: - Slice 2 is complete and moved to issues/done. - Verification passed: uv run poe syntax -P ag-ui --check; uv run poe test -P ag-ui; uv run poe markdown-code-lint; uv run ruff check packages/ag-ui/agent_framework_ag_ui/_state.py. - Commit hooks were skipped after poe-check repeatedly rewrote uv.lock ordering; the same checks were run manually and passed. * Python: update gitignore

Python: Fix AG-UI reasoning role and multimodal media parsing to follow specification (#5389)
* Fix AG-UI reasoning role and multimodal media value field parsing Fix two spec compliance issues in the AG-UI integration: 1. ReasoningMessageStartEvent now uses role='reasoning' instead of role='assistant', matching the AG-UI specification for reasoning messages. 2. _parse_multimodal_media_part now reads the 'value' field from source dicts (with fallback to 'data' for backward compatibility), matching the current AG-UI InputContentSource specification. Bump ag-ui-protocol dependency from ==0.1.13 to >=0.1.16,<0.2 to pick up the SDK fix that accepts role='reasoning' in ReasoningMessageStartEvent. Fix pre-existing pyright reportMissingImports errors for orjson in sample files, and fix import ordering in foundry-hosted-agents sample. Fixes #5340 Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Python: Fix AG-UI reasoning role and multimodal media parsing to follow specification Fixes #5340 * Remove unintended .maf-runtime-ready marker file Address PR review feedback: the .maf-runtime-ready file is not referenced anywhere in the repo and was left over from automation. Fixes #5340 * Python: Fix duplicate AG-UI multimodal 'value' parsing in snapshot path The snapshot normalization path used a second copy of the multimodal source parsing logic that still read the deprecated 'data' field. When clients sent base64 media with source={"type": "base64", "value": ...}, the snapshot event emitted by the server dropped the payload, causing AG-UI-compatible clients to crash on ingest. Extract the shared source-field extraction into _extract_multimodal_source_fields so both _parse_multimodal_media_part and the snapshot _legacy_binary_part stay in sync with the AG-UI spec. Add snapshot-path regression tests covering value-only, value-preferred-over-data, and the legacy data-field fallback.

Python: Pass client thread_id as session_id when constructing AgentSession in AG-UI (#5384)
* Pass thread_id as session_id when constructing AgentSession in AG-UI run_agent_stream() was constructing AgentSession without passing the client's thread_id as session_id, causing every request to receive a random UUID. This broke session continuity for HistoryProvider implementations that rely on session_id matching the client's thread_id. Pass session_id=thread_id in both the service-session and non-service code paths so the session identity is consistent with the AG-UI client.

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.doneandresponse.reasoning_summary_text.doneevents (#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. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * 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 Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * 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.

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 Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Python: Include reasoning messages in MESSAGES_SNAPSHOT events Fixes #4843 * 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 Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Address review feedback for #4843: Python: agent-framework-ag-ui: include reasoning messages in MESSAGES_SNAPSHOT --------- Co-authored-by: Copilot <copilot@github.com> Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

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.

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 Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Apply pre-commit auto-fixes * Refactor MCP tool emit functions and add missing tests (#4213) - Extract _emit_tool_result_common shared helper to eliminate duplication between _emit_tool_result and _emit_mcp_tool_result - Remove server_name prefix from tool_call_name in _emit_mcp_tool_call; display_name now equals tool_name directly - Add test for tool_name fallback to 'mcp_tool' when tool_name is None - Add test for output=None fallback to empty string in _emit_mcp_tool_result Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Address review feedback for #4213: review comment fixes --------- Co-authored-by: Copilot <copilot@github.com> Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

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

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

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.L.

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 - Add Role import where needed * 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 ChatMessage and Role API changes in devui package - Fix executor: ChatMessage signature change - 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 --------- Co-authored-by: Dmytro Struk <13853051+dmytrostruk@users.noreply.github.com>

fix(anthropic): fix duplicate ToolCallStartEvent in streaming tool calls (#3051)
When processing `input_json_delta` events, the Anthropic client was passing the tool name from the previous `tool_use` event. This caused ag-ui's `_handle_function_call_content` to emit a `ToolCallStartEvent` for every streaming chunk (since it triggers on `if content.name:`). This fix changes the behavior to pass an empty string for `name` in `input_json_delta` events, matching OpenAI's behavior where streaming argument chunks have `name=""`. The initial `tool_use` event still provides the tool name, so only one `ToolCallStartEvent` is emitted. Co-authored-by: Evan Mattson <35585003+moonbox3@users.noreply.github.com>

Python: Fix MCP tool result serialization for list[TextContent] (#2523)
* Fix MCP tool result serialization for list[TextContent] When MCP tools return results containing list[TextContent], they were incorrectly serialized to object repr strings like: '[<agent_framework._types.TextContent object at 0x...>]' This fix properly extracts text content from list items by: 1. Checking if items have a 'text' attribute (TextContent) 2. Using model_dump() for items that support it 3. Falling back to str() for other types 4. Joining single items as plain text, multiple items as JSON array Fixes #2509 * Address PR review feedback for MCP tool result serialization - Extract serialize_content_result() to shared _utils.py - Fix logic: use texts[0] instead of join for single item - Add type annotation: texts: list[str] = [] - Return empty string for empty list instead of '[]' - Move import json to file top level - Add comprehensive unit tests for serialization * Address PR review feedback: fix type checking and double serialization - Add isinstance(item.text, str) check to ensure text attribute is a string - Fix double-serialization issue by keeping model_dump results as dicts until final json.dumps (removes escaped JSON strings in arrays) - Improve docstring with detailed return value documentation - Add test for non-string text attribute handling - Add tests for list type tool results in _events.py path * Simplify PR: minimal changes to fix MCP tool result serialization Addresses reviewer feedback about excessive refactoring: - Reset _events.py to original structure - Only add import and use serialize_content_result in one location - All review comments addressed in serialize_content_result(): - Added isinstance(item.text, str) check - Use model_dump(mode="json") to avoid double-serialization - Improved docstring with explicit return value documentation - Empty list returns "" instead of "[]" * Refactor: Move MCP TextContent serialization to core prepare_function_call_results Per reviewer feedback, moved the TextContent serialization logic from ag-ui's serialize_content_result to the core package's prepare_function_call_results function. Changes: - Added handling for objects with 'text' attribute (like MCP TextContent) in _prepare_function_call_results_as_dumpable - Removed serialize_content_result from ag-ui/_utils.py - Updated _events.py and _message_adapters.py to use prepare_function_call_results from core package - Updated tests to match the core function's behavior * Fix failing tests for prepare_function_call_results behavior - test_tool_result_with_none: Update expected value to 'null' (JSON serialization of None) - test_tool_result_with_model_dump_objects: Use Pydantic BaseModel instead of plain class * Fix B903 linter error: Convert MockTextContent to dataclass The ruff linter was reporting B903 (class could be dataclass or namedtuple) for the MockTextContent test helper classes. This commit converts them to dataclasses to satisfy the linter check.
