Fix hosted agent samples Docker build failures due to experimental API warnings (#4641 )

Add #pragma warning disable directives to suppress experimental API
diagnostics that cause build errors in Docker isolation (where repo-level
Directory.Build.props is not inherited):

- AgentWithHostedMCP: suppress MEAI001 (HostedMcpServerTool) and OPENAI001
  (GetResponsesClient)
- FoundrySingleAgent: suppress CA2252 (AIProjectClient preview features)
- FoundryMultiAgent: suppress CA2252 (AIProjectClient preview features)

Fixes #4365

[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: 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.

Fixes #4529

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.

- test_create_state_snapshot_isolates_nested_objects: verifies the
  production _create_state_snapshot helper creates a true deep copy

These tests ensure a regression back to shallow copy would be caught.

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

  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.

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 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.

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

* Remove unnecessary local variable in __deepcopy__

Inline cls._SHALLOW_COPY_FIELDS directly in the loop check instead of
assigning to a local variable first, per review feedback.

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.

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

- Use collections.abc.Mapping instead of dict for isinstance check in

- Add test for object-style chat_options with optional options dict parameter.
- Add test verifying existing conversation_id gets overwritten (idempotent).

* Remove unnecessary Microsoft.Agents.AI.* package references (transitive from AgentFramework)

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

* Add DefaultAzureCredential production warning comments to all HostedAgents samples

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

* Update HostedAgents READMEs to reflect DefaultAzureCredential usage

Replace AzureCliCredential references with DefaultAzureCredential in all
HostedAgents README files to match the actual sample code.

* Replace Microsoft.Extensions.AI.OpenAI with Microsoft.Agents.AI.OpenAI and remove AsIChatClient()

Swap package references from Microsoft.Extensions.AI.OpenAI to
Microsoft.Agents.AI.OpenAI across all 6 HostedAgents samples. This enables
using the AsAIAgent() extension directly on ChatClient/ResponsesClient
(from OpenAI.Chat/OpenAI.Responses namespaces), removing the intermediate
AsIChatClient() call in 3 samples where it was unnecessary.

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

* Use explicit types and AsAIAgent() extensions across all HostedAgents samples

Replace var with explicit types for clarity in all 6 samples. Replace
new ChatClientAgent() constructor calls with chatClient.AsAIAgent()
extension method in AgentWithLocalTools and AgentsInWorkflows.

.NET: Fix filter combine logic for ChatHistoryMemoryProvider (#4501 )

* Fix filter combine logic for ChatHistoryMemoryProvider

* Replace var with explicit types in filter building code and test

Address PR review nit: use explicit types instead of var for better
readability in the filter-building logic and the new combined filter
compilation test.

Python: Improve ag-ui tests and coverage (#4442 )

* Improve ag-ui tests and coverage

* fix tests paths

* Fixes

* Improve AG-UI test robustness and correctness

- Map toolName → tool_call_name in SSE helpers for TOOL_CALL_START events
- Fail loudly on malformed SSE JSON in parse_sse_response() instead of silently dropping
- Detect duplicate TOOL_CALL_START/TOOL_CALL_END in assert_tool_calls_balanced()
- Remove fragile source line reference from test docstring
- Add found guard in test_client_tool_sets_additional_properties to prevent vacuous pass

Python: Fix RedisContextProvider for redisvl 0.14.0 by using AggregateHybridQuery (#3954 )

* Initial plan

* Fix: Replace alpha with linear_alpha in HybridQuery for redisvl 0.14.0 compatibility

Co-authored-by: markwallace-microsoft <127216156+markwallace-microsoft@users.noreply.github.com>

* Address code review: Improve test readability and add explanatory comment

Co-authored-by: markwallace-microsoft <127216156+markwallace-microsoft@users.noreply.github.com>

* Add CHANGELOG entry for redisvl 0.14.0 compatibility fix

Co-authored-by: eavanvalkenburg <13749212+eavanvalkenburg@users.noreply.github.com>

* Use AggregateHybridQuery instead of HybridQuery for backward compatibility

Replace HybridQuery with AggregateHybridQuery to preserve existing functionality that works with older Redis versions. The new HybridQuery in redisvl 0.14.0 requires Redis 8.4.0+ and uses a different API, while AggregateHybridQuery maintains compatibility with the original implementation.

Co-authored-by: TaoChenOSU <12570346+TaoChenOSU@users.noreply.github.com>

* Fix test to use linear_alpha parameter matching _redis_search implementation

The test was passing alpha as a keyword argument to _redis_search(), but the
method uses linear_alpha to match the redisvl 0.14.0 AggregateHybridQuery API.

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

* Fix pyright error: use alpha parameter matching AggregateHybridQuery API

AggregateHybridQuery expects 'alpha', not 'linear_alpha'. Updated the
_redis_search method parameter and the test accordingly.
