Python: Fix RUN_FINISHED.interrupt to accumulate all interrupts when multiple tools need approval (#4717 )

* Fix flow.interrupts overwrite when multiple tools need approval (#4590)

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()
ensures RUN_FINISHED.interrupt contains all pending approvals.

* Add test for streaming path with multiple confirm_changes interrupts (#4590)

Add integration test exercising run_agent_stream with multiple predictive
tool calls requiring confirmation. Verifies that flow.interrupts.append()
correctly accumulates all interrupt entries and they appear in the
RUN_FINISHED event.

Also confirms FlowState already declares interrupts field with
default_factory=list, addressing the AttributeError concern from review.

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.

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

* 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.

Python: A2AAgent defaults name/description from AgentCard (#4661 )

* Python: A2AAgent defaults name/description from AgentCard

When an AgentCard is provided but name/description are not explicitly
set, A2AAgent now falls back to agent_card.name and agent_card.description.
This avoids redundant duplication when constructing A2AAgent instances,
especially in GroupChat orchestrations where name and description are
essential for routing decisions.

Explicit values still take precedence over card values.

fix: omit toolConfig when tool_choice="none" in BedrockChatClient (#4535 )

Bedrock's Converse API only accepts "auto", "any", or "tool" as valid
toolChoice keys. The previous code mapped tool_choice="none" to
{"none": {}}, which causes a botocore.exceptions.ParamValidationError.

When tool_choice="none" (set by FunctionInvocationLayer after exhausting
max iterations), the fix now omits toolConfig entirely so the model
won't attempt tool calls.

Added tests for tool_choice="none", "auto", and "required" modes.

Python: Fix state snapshot to use deepcopy so nested mutations are detected in durable workflow activities (#4518 )

* Use deepcopy for state snapshot to detect nested mutations (#4500)

Replace dict() shallow copy with copy.deepcopy() when snapshotting
workflow state before activity execution. The shallow copy shared
references to nested objects (dicts, lists), so in-place mutations by
executors were reflected in both the snapshot and live state, producing
an empty diff and preventing state updates from propagating to
downstream activities.

Fix CWE-863: Validate function approval responses in DevUI executor (#4598 )

The DevUI /v1/responses endpoint accepts function_approval_response content
without verifying that the request_id corresponds to a real pending approval
request issued by the server. This allows forged approval responses to
execute arbitrary tools with attacker-controlled arguments, bypassing
approval_mode='always_require'.

Changes:
- Track outgoing approval requests in a server-side registry
  (_pending_approvals) keyed by request_id
- Validate incoming approval responses against this registry; reject
  any response whose request_id was not issued by the server
- Use server-stored function_call data (tool name, arguments, call_id)
  instead of client-supplied data when constructing the approval response
- Consume request_ids on use (pop from registry) to prevent replay attacks

Tests:
- 8 new tests covering forged rejection, server-data enforcement,
  anti-replay, multiple independent approvals, and edge cases

* Validate approval responses against server-side pending request registry

* improvements

* pin GHCP sdk version to non-breaking for now

* Pin CHCP sdk to LKG.

* really fix GHCP sdk pkg version

* Fix HITL approval validation security gaps and memory leak

- Validate rejected approval responses against pending_approvals registry,
  not just approved ones. Fabricated rejections without a prior request are
  now stripped from messages before reaching the LLM.
- Bound _pending_approvals with OrderedDict + LRU eviction (max 10k) to
  prevent unbounded memory growth from abandoned approval requests.
- Skip registration when function_call.name is None/empty; log warning
  when content.id or function_call is missing at registration time.
- Document pending_approvals parameter in run_agent_stream docstring.
- Add test for fabricated rejection attack scenario.
- Assert pending approval entry is preserved after function name mismatch.
- Pre-populate pending_approvals in rejection test for correct validation.

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: add ToolResultCompactionStrategy and CompactionProvider

Add ToolResultCompactionStrategy that collapses older tool-call groups
into short summary messages (e.g. [Tool calls: get_weather]) while
keeping the most recent groups verbatim. This mirrors the .NET
ToolResultCompactionStrategy from PR #4533.

Add CompactionProvider as a context-provider that auto-applies compaction
before each agent turn and stores compacted history in session state
after each turn.

Includes tests and samples for both features.

* Python: add ToolResultCompactionStrategy, CompactionProvider, and skip_excluded

- ToolResultCompactionStrategy collapses older tool-call groups into
  [Tool results: func_name: result] summaries with bidirectional tracing
  (same pattern as SummarizationStrategy).
- CompactionProvider as BaseContextProvider with separate before_strategy
  and after_strategy parameters. before_strategy compacts loaded context;
  after_strategy compacts stored history via history_source_id.
- InMemoryHistoryProvider gains skip_excluded flag to filter out messages
  marked as excluded by compaction strategies.
- Tests, samples, and exports updated.

* Fix: ensure summary messages from both strategies get full compaction annotations

SummarizationStrategy was not calling annotate_message_groups after
inserting its summary message, so the summary lacked core group
annotations (id, kind, index, has_reasoning, _excluded). Added the
missing call. ToolResultCompactionStrategy already had it.

Added tests verifying both strategies produce fully annotated summaries.

Python: Fix executor_completed event with non-copyable raw_representation in mixed workflows (#4493 )

* Python: Fix `executor_completed` event with non-copyable raw_representation in mixed workflows

Fixes #4455

* fix(#4455): use class-level sets for deepcopy field exclusion

- SerializationMixin.__deepcopy__: check type(self).DEFAULT_EXCLUDE
  instead of hardcoding 'raw_representation'
- Content.__deepcopy__: add _SHALLOW_COPY_FIELDS class variable and
  check against it instead of hardcoding
- Fix tautological assertion in test (was always True)
- Add second excluded field to test to verify DEFAULT_EXCLUDE is
  respected generically

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

* Decouple __deepcopy__ from DEFAULT_EXCLUDE in SerializationMixin (#4455)

Introduce _SHALLOW_COPY_FIELDS class variable in SerializationMixin to
separate deep-copy semantics from serialization semantics. Previously,
__deepcopy__ used DEFAULT_EXCLUDE to decide which fields to shallow-copy,
conflating 'not serialized' with 'not safe to deep-copy'. A field added
to DEFAULT_EXCLUDE purely for serialization (e.g. additional_properties)
would be silently shared between original and copy.

- Add _SHALLOW_COPY_FIELDS (default {'raw_representation'}) to
  SerializationMixin, matching the pattern already used by Content
- Update __deepcopy__ to read from _SHALLOW_COPY_FIELDS instead of
  DEFAULT_EXCLUDE
- Add test verifying DEFAULT_EXCLUDE fields are deep-copied unless
  also in _SHALLOW_COPY_FIELDS
- Add test for Content._SHALLOW_COPY_FIELDS identity preservation
- Add test for ChatResponse deep-copying additional_properties

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

* Add test for _SHALLOW_COPY_FIELDS and DEFAULT_EXCLUDE independence

Add test_deepcopy_shallow_copy_fields_override_default_exclude to verify
that a field in both DEFAULT_EXCLUDE and _SHALLOW_COPY_FIELDS is
shallow-copied (controlled by _SHALLOW_COPY_FIELDS), while a field in
DEFAULT_EXCLUDE only is still deep-copied. This addresses review comment
#11 ensuring the two class variables control independent concerns.

Python: Prevent pickle deserialization of untrusted HITL HTTP input (#4566 )

* fix: prevent pickle deserialization of untrusted HITL input

Add strip_pickle_markers() to sanitize HTTP input before it reaches
pickle.loads() via the checkpoint decoding path. Applied as a 3-layer
defence-in-depth:

1. _app.py: sanitize req.get_json() at the HTTP boundary
2. _workflow.py: sanitize in _deserialize_hitl_response() before decode
3. _serialization.py: sanitize in reconstruct_to_type() as final guard

Any dict containing __pickled__ or __type__ markers from untrusted
sources is replaced with None, blocking arbitrary code execution via
crafted payloads to POST /workflow/respond/{instanceId}/{requestId}.

Includes 12 new unit tests covering the sanitizer and end-to-end
attack prevention.

* refactor: address review concerns for pickle fix

1. Remove deserialize_value() fallback in _deserialize_hitl_response
   untrusted HITL data now returns as-is when no type hint is available,
   never flowing into pickle.loads().

2. Move strip_pickle_markers() out of reconstruct_to_type()  the function
   is general-purpose again; untrusted-data callers are responsible for
   sanitizing first (documented with NOTE comment).

3. Define _PICKLE_MARKER/_TYPE_MARKER as local constants with import-time
   assertions against core's values  decouples from private names while
   failing loudly if core ever changes them.

4. Update tests to reflect new responsibility boundaries.

* fix: simplify warning message and fix ruff RUF001 lint

* fix: suppress pyright reportPrivateUsage on core marker imports

* Lower marker-strip log from warning to debug to avoid log flooding

* Replace assert with RuntimeError for marker sync checks (ruff S101)

* Fix pyright and ruff CI errors in security fix

- Use cast() for dict/list comprehensions in strip_pickle_markers (pyright)
- type: ignore for narrowed dict return in _workflow.py (pyright)
- Simplify marker imports: use core constants directly, remove local copies
- Remove duplicate pyright ignore comment

* Remove duplicate end-to-end test in TestStripPickleMarkers

* Suppress mypy redundant-cast on list cast needed by pyright

Python: Add A2A server sample (#4528 )

* Python: Add A2A server sample and fix client streaming bug

Add a pure Python A2A server sample so testing the A2A client no longer
requires running the .NET server. The server uses the a2a-sdk's
A2AStarletteApplication with uvicorn and supports three agent types
(invoice, policy, logistics) backed by AzureOpenAIResponsesClient.

New files:
- a2a_server.py: Main server entry point with CLI args
- agent_executor.py: Bridges a2a-sdk AgentExecutor to Agent Framework
- agent_definitions.py: Agent and AgentCard factory definitions
- invoice_data.py: Mock invoice data and query tool functions
- a2a_server.http: REST Client requests for testing

Also fixes a streaming bug in agent_with_a2a.py where async with was
used on ResponseStream which does not support the async context manager
protocol. Changed to async for to match all other samples.

* Auto-finalize ResponseStream on iteration completion

When a ResponseStream is fully consumed via async iteration,
automatically trigger finalization (finalizer + result hooks).
This ensures session history is persisted in streaming multi-turn
conversations without requiring an explicit get_final_response() call.

- Add auto-finalize call in __anext__ on StopAsyncIteration
- Guard inner stream finalization to prevent double-execution
- Re-check _finalized after iteration in get_final_response()
- Add tests for auto-finalization and streaming session history
- Revert sample file renames from previous commit

* Python: Exclude conversation_id from chat completions options (#4315)

When a session with service_session_id is passed to an agent using the
Chat Completions client, conversation_id leaked through _prepare_options()
into AsyncCompletions.create(), causing an 'unexpected keyword argument'
error. The Responses client already excluded conversation_id but the Chat
Completions client did not.

Added conversation_id to the exclusion set in _prepare_options().

Python: Fix conversation-id propagation when chat_options is a dict (#4340 )

* Fix #4305: Handle dict chat_options in _update_conversation_id

_update_conversation_id assumed chat_options had attribute access, but
ChatOptions is a TypedDict (dict). When a dict was passed, setting
.conversation_id raised AttributeError. Now checks isinstance(dict) and
uses key access for dicts, falling back to attribute access for objects.

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

* Address PR feedback: use Mapping ABC and add missing tests (#4305)

- Use collections.abc.Mapping instead of dict for isinstance check in
  _update_conversation_id, making it more robust for non-dict mapping types.
- Add test for object-style chat_options with optional options dict parameter.
- Add test verifying existing conversation_id gets overwritten (idempotent).

* Remove unnecessary Mapping check in _update_conversation_id (#4305)

* Reduce pyright cost in handoff cloning

Simplify cloned_options construction in HandoffAgentExecutor to avoid expensive TypedDict narrowing/inference in _handoff.py, which was causing pyright to spend a long time in orchestrations.

Python: Add propagate_session to as_tool() for session sharing in agent-as-tool scenarios (#4439 )

* Python: Add propagate_session parameter to as_tool() for session sharing

Add opt-in session propagation in agent-as-tool scenarios. When
propagate_session=True, the parent agent's AgentSession is forwarded
to the sub-agent's run() call, allowing both agents to share session
state (history, metadata, session_id).

- Add propagate_session parameter to BaseAgent.as_tool() (default False)
- Include session in additional_function_arguments so it flows to tools
- Add 3 tests for propagation on/off and shared state verification
- Add sample showing session propagation with observability middleware

Python: feat(claude): add plugins, setting_sources, thinking, and effort options to ClaudeAgentOptions (#4425 )

* feat(claude): add plugins, setting_sources, thinking, and effort options

Add four Claude Agent SDK options to ClaudeAgentOptions that are clean
passthroughs with no abstraction conflicts:

- plugins: load Claude Code plugins programmatically via SdkPluginConfig
- setting_sources: control which .claude settings files are loaded
- thinking: modern extended thinking config (adaptive/enabled/disabled)
- effort: control thinking depth (low/medium/high/max)

* feat(claude): remove max_thinking_tokens, add plugins/setting_sources/thinking/effort

Remove the deprecated max_thinking_tokens field from ClaudeAgentOptions
in favor of the new thinking field (ThinkingConfig).

Add four Claude Agent SDK options as clean passthroughs:
- plugins: load Claude Code plugins via SdkPluginConfig
- setting_sources: control which .claude settings files are loaded
- thinking: extended thinking config (adaptive/enabled/disabled)
- effort: thinking depth control (low/medium/high/max)

Python: Fix PowerFx eval crash on non-English system locales by setting CurrentUICulture to en-US (#4408 )

* Fix #4321: Set CurrentUICulture to en-US in PowerFx eval()

On non-English systems, CultureInfo.CurrentUICulture causes PowerFx to
emit localized error messages. The existing ValueError guard only matches
English strings ("isn't recognized", "Name isn't valid"), so undefined
variable errors crash instead of returning None gracefully.

Fix: save and restore CurrentUICulture alongside CurrentCulture before
calling engine.eval(), ensuring error messages are always in English.

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

* Reuse single CultureInfo instance to avoid redundant allocations

Cache CultureInfo("en-US") in a local variable instead of instantiating
it twice per eval() call, as suggested in PR review.

Fixes #4321

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

* Add assertion for CurrentUICulture restoration after eval

Assert that the production code's finally-block correctly restores
CurrentUICulture to it-IT after eval returns, covering future
regressions where the culture could leak.

The CultureInfo caching suggestion (comment #2) was already
implemented in the production code.

Python: Fix MCP tools duplicated on second turn when runtime tools are present (#4432 )

* Fix MCP tools duplicated on second turn when runtime tools are present

When AG-UI's collect_server_tools pre-expands MCP functions on turn 2
(after the MCP server is connected), _prepare_run_context unconditionally
appends them again from self.mcp_tools, duplicating every MCP tool.

Skip MCP functions whose names already exist in the final tool list,
following the same name-based dedup pattern used in _merge_options.

Fixes #4381
