- pyupgrade: drop forward-reference string annotations in _mcp.py (Python 3.10+ resolves them natively now that MCPTaskOptions is defined before use).
- AGENTS.md: align reconnect description with current behavior. Phase 1 (initial tools/call) does NOT retry on connection loss; raises 'connection lost; task state unknown' instead, so a server that accepted the request but lost the response cannot start the operation twice. Phase 2 (tasks/get / tasks/result) still reconnects once against the same task_id.

* Add MCP-based skills discovery (McpSkill, McpSkillsSource, McpSkillResource)
Implement Agent Skills discovery over MCP following the SEP-2640 convention:
- McpSkillsSource: reads skill://index.json to discover skills served by an MCP server
- McpSkill: lazily fetches SKILL.md content via resources/read on demand
- McpSkillResource: wraps MCP resource results (text and binary)
- Path traversal protection in get_resource for defense in depth
- Samples for Foundry Toolbox and standalone MCP skills server
- Comprehensive unit tests (514 lines)

* Branch on McpError.error.code so only not-found errors return empty
Previously _try_read_index() and get_resource() swallowed every McpError
as 'no skills available', making auth failures, server crashes, and
connection drops indistinguishable from a server that simply has no
skills.
Now only two codes are treated as not-found:
- -32002 (MCP-spec Resource not found)
- -32601 (METHOD_NOT_FOUND — server lacks resources/read)
All other McpError codes and non-McpError exceptions propagate with a
warning log, surfacing real failures visibly.

* Python: progressive tool exposure via FunctionInvocationContext
Add first-class progressive tool exposure to the Python core function-calling
loop. Tools can now add or remove real FunctionTool schemas at runtime via the
injected FunctionInvocationContext, taking effect on the next iteration of the
loop.
- FunctionInvocationContext gains a live `tools` list plus experimental
`add_tools()` / `remove_tools()` helpers (feature: PROGRESSIVE_TOOLS).
- The function-calling loop establishes a run-local, normalized tools list and
threads it into the context at both invocation paths so mutations propagate.
- Add a sample (dynamic_tool_exposure.py) and a tools samples README, including
a note that CodeAct providers (Monty/Hyperlight) use their own provider-level
tool management instead.
Supersedes #3877.

* Make add_tools atomic and surface swallowed function errors
Address review feedback on progressive tool exposure:
- add_tools now validates the full batch against a throwaway copy before
committing, so a duplicate-name clash partway through a sequence leaves
the live tool list unchanged (all-or-nothing).
- _auto_invoke_function now logs a warning (with traceback) when a tool
raises, so contract errors such as a duplicate-name ValueError from
add_tools are debuggable without enabling include_detailed_errors.

* Avoid retaining tracebacks when logging swallowed function errors
Logging with exc_info=exc fed the exception traceback to the logging
machinery, whose frame references created reference cycles collected
lazily by the cyclic GC. On Windows that could drop a hyperlight
WasmSandbox on a non-owning thread ("unsendable, dropped on another
thread"), crashing the xdist worker. Log a pre-formatted message with
the exception repr instead, so no traceback object is retained.

* Fix FoundryAgent stripping model from PromptAgent requests
Move run_options.pop('model', None) inside the _uses_foundry_agent_session()
conditional so that model is only stripped for hosted agent sessions (where
the server manages the model) and preserved for PromptAgent requests that
require it in the Responses API call.
Fixes#5525
* test: add coverage for resp_* continuation preserving model
Adds test_raw_foundry_agent_chat_client_prepare_options_preserves_model_for_resp_continuation
to explicitly verify that HostedAgent v1 / v2-no-session paths (where conversation_id
starts with resp_) preserve model and previous_response_id without triggering the
hosted-session gate.

* Python: Fix OTLP HTTP base-endpoint losing /v1/{signal} auto-append
Per the OTel spec, OTEL_EXPORTER_OTLP_ENDPOINT is a *base* URL for HTTP —
the SDK auto-appends /v1/traces, /v1/metrics, /v1/logs when it reads the
env var directly. Signal-specific endpoint env vars are *full* URLs used
verbatim.
_get_exporters_from_env read the base endpoint and forwarded it as the
constructor ``endpoint=`` argument, which the SDK always treats as a full
signal URL. As a result, with OTEL_EXPORTER_OTLP_ENDPOINT=http://localhost:4318
and HTTP protocol, the exporter sent to http://localhost:4318 instead of
http://localhost:4318/v1/traces (and likewise for metrics/logs).
Replicate the spec's auto-append here when falling back to the base
endpoint under HTTP. gRPC behavior is unchanged.
* Python: Fix mypy type errors in OTLP endpoint assignment
Pre-declare traces_endpoint, metrics_endpoint, logs_endpoint as
str | None before the if/else block. Mypy inferred str from the
if-branch f-string assignments and then rejected the str | None
expressions in the else-branch as incompatible.

Addresses 4 Copilot review comments on PR #6101:
1. assert_dimension_score_at_least: drop the (not evaluator or found_any) guard so require_applicable=True correctly raises when the named evaluator produces no entries for the dimension. Adds TestRubricAssertions covering the regression.
2. GeneratedEvaluatorRef docstring: reword to describe actual behaviour (pinning recommended, not required) so it matches the dataclass default and FoundryEvals warning path.
3. _poll_generation_job: switch from asyncio.get_event_loop() to get_running_loop() and bound the per-iteration sleep by remaining time, matching _poll_eval_run.
4. generate_rubric: type category as Literal['quality','safety'] and validate at the entry point with a ValueError; drop the silent 'invalid -> quality' rewrite in _generation_job_to_ref. Adds a regression test.

* Python: feat(foundry-evals): hosted-agent-aware rubric generation
* Auto-detect hosted Foundry agents in agent_as_eval_source: when the
agent's chat_client exposes a string agent_name (the convention used
by RawFoundryAgentChatClient for PromptAgents/HostedAgents), emit a
type='agent' EvalGenerationSource so the service fetches instructions
and tools from the agent registry instead of relying on the local
wrapper (which holds neither for hosted agents).
* Add hosted_agent_version kwarg and a new agent_version field on
EvalGenerationSource so PromptAgent runs can pin to a specific hosted
version for reproducible rubric generation.
* Add force_prompt_source escape hatch to bypass auto-detection and
always emit a rendered prompt dossier - useful when the local wrapper
carries overrides the service-side agent doesnt see.
* Fix _to_sdk_source for dataset sources: SDK ctor takes name=/version=,
not dataset_name=/dataset_version=. The mismatch would raise TypeError
against the real azure-ai-projects 2.3.0a* SDK; only unmocked
integration paths were affected.
Tests cover: auto-detection happy path, versionless hosted agent,
explicit hosted_agent_version forwarding, force_prompt_source override,
non-string chat_client attrs (MagicMock test doubles) not mis-detected,
agent_version forwarded through _to_sdk_source, and the corrected
dataset SDK kwarg names.

* fix(foundry-evals): accept canonical dimension_scores key per docs
The published Foundry rubric-evaluator output (Microsoft Learn 'Rubric evaluators' reference) places per-dimension breakdowns under properties.dimension_scores, not properties.rubric_scores. The parser now tries dimension_scores first and falls back to rubric_scores for preview-build compatibility, and tolerates non-list payloads (e.g. MagicMock auto-attrs) by trying the next candidate when parsing yields zero entries.
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* feat(foundry-evals): add manual create_rubric_evaluator
Adds FoundryEvals.create_rubric_evaluator as the agent-framework surface over project_client.beta.evaluators.create_version. This is the manual counterpart to generate_rubric: callers supply RubricDimension instances (authored locally, ported from another framework, or hand-tuned) and we POST a RubricBasedEvaluatorDefinition. The service auto-attaches the non-editable residual dimension (general_quality for quality, general_policy_compliance for safety).
Per the Microsoft Learn 'Rubric evaluators' reference, the auto-generation path (create_generation_job) is primarily a portal/UI feature; external SDK clients with rich local agent context are better served by manual create_version. This keeps generate_rubric for users who want to round-trip through a Foundry-registered agent.
Validation up front: weight must be in [1,10], ids unique, descriptions non-empty, pass_threshold in [0,1]. The returned GeneratedEvaluatorRef is identical in shape to one obtained from generate_rubric, so downstream evaluators= lists work unchanged.

* samples(foundry-evals): manual rubric sample + namespace re-exports
Adds evaluate_with_manual_rubric_sample.py demonstrating the end-to-end dev scenario for FoundryEvals.create_rubric_evaluator: hand-author a list of RubricDimension, register via create_rubric_evaluator, then use the pinned GeneratedEvaluatorRef alongside built-in evaluators in an agent regression run.
Also re-exports RubricDimension, GeneratedEvaluatorRef, build_sources, and load_evals_config from agent_framework.foundry (both the lazy runtime shim and the type stub) so the rubric samples can import everything from a single namespace; the auto-generate sample was previously broken because the shim was missing build_sources / load_evals_config.
Updates the foundry-evals README with a chooser entry for the two rubric paths.

* feat(foundry-evals): remove rubric creation flows; keep consumption only
Reframes agent-framework as a pure consumer of Foundry rubric evaluators: scoring against rubrics that already exist (authored in the Foundry portal or via the dedicated SDK / REST surface) instead of creating them from the SDK.
Removed creation surface area:
- FoundryEvals.generate_rubric (auto-generate path) and create_rubric_evaluator (manual path), plus all _GenerationSdkTypes / _ManualRubricSdkTypes / _to_sdk_dimensions / _coalesce_generation_sources / _to_sdk_source / _poll_generation_job / _generation_job_to_ref / _evaluator_version_to_ref / _get_beta_evaluators / _import_*_sdk_types helpers.
- EvalGenerationSource (the input source discriminator), RubricDimension (the input dimension type), agent_as_eval_source / workflow_as_eval_source / _detect_hosted_foundry_agent helpers, and the YAML-config loader (_evals_config.py with RubricGenerationSpec / RubricSourceSpec / parse_evals_config / load_evals_config / build_sources).
- BaseAgent.as_eval_source / Workflow.as_eval_source plus the _render_agent_dossier / _render_workflow_dossier helpers in core. These existed only to feed the now-removed generation pipeline.
- Samples evaluate_with_generated_rubric_sample.py, evaluate_with_manual_rubric_sample.py, and evaluators.yaml. Replaced with a short README section showing how to reference an existing rubric evaluator via GeneratedEvaluatorRef.
Kept (consumption surface):
- GeneratedEvaluatorRef, slimmed to (name, version, display_name). Still accepted alongside built-in evaluator strings in FoundryEvals(evaluators=[...]). Versionless refs still warn.
- RubricScore on EvalScoreResult.dimensions plus EvalResults.assert_dimension_score_at_least for per-dimension CI gates.
- _parse_dimension_entries / _extract_rubric_scores output parsing (both canonical dimension_scores and the legacy rubric_scores key).
Tests: 160/160 foundry unit tests and 71/71 core local-eval tests pass; pyright is clean across changed files. The pre-existing tests/core/test_telemetry.py::test_detect_hosted_fallback_import_error failure is unrelated and reproduces on the prior commit.

* samples(foundry-evals): add evaluate_with_rubric_sample
Adds a runnable end-to-end sample showing how to consume a pre-existing rubric evaluator created in Foundry: reference it with GeneratedEvaluatorRef(name, version), mix it with built-in evaluators in FoundryEvals, and gate CI with assert_dimension_score_at_least on a specific dimension.

* fix(foundry-evals): satisfy mypy on _fetch_output_items
mypy infers OutputItemListResponse.sample as dict[str, object] | None while pyright correctly infers the typed Sample model.

Move all of them to the existing top-level imports; the symbols are the same across tests and the local imports were redundant.

* fix: safely serialize function-call arguments in core observability
Apply make_json_safe() to content.arguments in _to_otel_part() before
building the otel message dict, so that dataclass/framework payloads

_capture_messages() calls json.dumps().

TypeError at runtime.
- Wrap each call in try/except TypeError to handle callables with

int) cannot cause json.dumps to raise TypeError.

* Initial plan
* Fix integration test worker crashes on Python 3.13
Three changes to prevent pytest-xdist workers from crashing during
Azure Functions integration tests:
1. Add `start_new_session=True` to subprocess on Linux so signals
(e.g. from test-timeout) cannot propagate between the func host
and the xdist worker process.
2. Add an overall 100-second budget to the fixture setup loop so
the retry logic never exceeds the 120-second test timeout. When
pytest-timeout's thread method fires during fixture setup and the
thread doesn't respond, it calls os._exit() which kills the
xdist worker – this is the root cause of the "Not properly
terminated" crashes.
3. Remove the `UV_PYTHON: "3.10"` workaround from both workflow
files so integration tests actually run on Python 3.13.

* Fix func worker segfault on Python 3.13 by redirecting worker to Python 3.12
The Azure Functions Python worker crashes with SIGSEGV (exit code 139)
on Python 3.13 due to protobuf C extension (google._upb) compatibility
issues. When the test runner uses Python >=3.13, the conftest now
automatically finds a compatible Python 3.10-3.12 and sets
languageWorkers__python__defaultExecutablePath so the func host uses
it for the worker process.
The CI setup action also ensures Python 3.12 is available on the
runner, falling back to uv python install if the system doesn't have
it.

* Address code review: add path validation, clarify version range and config key format
Co-authored-by: larohra <41490930+larohra@users.noreply.github.com>
* Run func worker natively on Python 3.13 by disabling dependency isolation
Replace the Python 3.12 redirect workaround with the proper fix:
set PYTHON_ISOLATE_WORKER_DEPENDENCIES=0 on Python >=3.13.
The segfault (exit code 139) is caused by the Azure Functions worker's
module isolation mechanism conflicting with protobuf's C extensions
(google._upb) on Python 3.13. Disabling isolation lets the worker
load dependencies from the app's own environment, which avoids the
crash while keeping everything running on Python 3.13.

* Fix streaming artifact coalescing and address PR review feedback
A2AExecutor fix:
- Generate a stable artifact_id per stream in _run_stream so all streaming
chunks share the same ID, enabling proper append=True coalescing per the
A2A spec (TaskArtifactUpdateEvent with same artifactId).
- Previously, item.message_id was None for OpenAI/Foundry streaming updates,
causing the SDK to generate a new random UUID per token (100+ separate
artifacts instead of 1 appended artifact).
Sample improvements:
- Replace join workaround with response.text now that coalescing works
- Add background=True to stream reconnection resume call (required for
continuation token emission on in-progress tasks)
- Fix type ignore specificity in polling sample

* Adding AgentFileStore and FileAccessProvider to support file ased operations for agents.
* Address PR review feedback on FileAccessProvider
- Probe symlinks on the unresolved candidate path so in-root symlinks
cannot silently pass and out-of-root symlinks surface the correct
error message.
- Validate matching_lines elements in FileSearchResult.from_dict and
raise a clean ValueError for non-mapping entries.
- Cap search regex pattern length (256 chars) via a new
_compile_search_regex helper to mitigate ReDoS, and surface the cap
in the file_access_search_files tool description.
- Skip non-UTF-8 files during filesystem search instead of aborting
the entire directory walk.
- Replace the module-scope trailing string in the data-processing
sample with comments to avoid Ruff B018.
- Remove the checked-in working/region_totals.md sample artifact so
the save flow works from a clean checkout.
- Expand the Windows stdout reconfiguration comment in task_runner.py
for clarity.
- Add tests for invalid/oversize regex, non-UTF-8 file search, and
in-root symlink rejection.

* Fix mypy redundant-cast in FileSearchResult.from_dict
Use cast(list[object], ...) instead of cast(list[Any], ...) so the

* Tighten path normalization and directory resolution in FileAccess
- _normalize_relative_path now strips surrounding whitespace up front
so leading/trailing spaces never leak into file segments, and
rejects trailing path separators for file paths so 'foo/' is no
longer silently coerced to 'foo'.
- FileSystemAgentFileStore._resolve_safe_directory_path normalizes
with is_directory=True and maps an empty normalized result to the
root. This matches InMemoryAgentFileStore so whitespace-only
directory inputs resolve to the root instead of raising.
- Added tests for whitespace stripping, trailing-separator rejection,
and whitespace-only directory listing on the filesystem store.
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* Harden FileAccess search and atomic save in store API
- Add wall-clock timeout (10s) around regex scans so a pathological pattern (e.g. `(a+)+`) below the length cap cannot stall the event loop.
- Offload the InMemoryAgentFileStore regex scan to a worker thread, matching the filesystem store.
- Fail closed when `Path.is_symlink` raises during the safe-path probe so a permission error cannot silently bypass the symlink/reparse-point rejection.
- Add `overwrite: bool = True` to `AgentFileStore.write_file`; the in-memory store performs the check under the existing lock and the filesystem store uses `open(mode='x')` so concurrent callers cannot race past `overwrite=False`.
- `file_access_save_file` now relies on the atomic store call instead of a separate `file_exists` round-trip.

* Fix Python 3.10 timeout handling and add directory arg to list/search tools
- Catch asyncio.TimeoutError in _run_search_with_timeout. In Python 3.10
asyncio.wait_for raises asyncio.exceptions.TimeoutError, which is
distinct from the builtin TimeoutError (the two were unified in 3.11).
Catching the asyncio alias works on every supported version.
- Add an optional directory parameter to file_access_list_files and
file_access_search_files so agents can enumerate / scope searches to
nested folders, not just the store root.

* Address FileAccess review feedback: case, errors, signal, TOCTOU
- InMemoryAgentFileStore now stores (display_name, content) so list_files
and search_files return the original-case names callers wrote, matching
the behaviour of FileSystemAgentFileStore on case-preserving filesystems
and removing the silent in-memory vs. on-disk contract divergence.
- FileSystemAgentFileStore.read_file raises ValueError instead of letting
UnicodeDecodeError bubble for binary / non-UTF-8 input, restoring
symmetry with search_files (which still skips) and giving the tool
layer a recoverable type to translate.
- Tool wrappers now catch ValueError and OSError around every operation
and surface them as readable strings, so 'you used ..' and 'the file
already exists' are both reported to the model the same way instead of
the former crashing out as an unhandled exception.
- _search_files_sync logs per skipped non-UTF-8 file at WARNING and an
aggregate INFO summary so operators can distinguish 'no matches' from
'half the corpus was unreadable'.
- FileSystemAgentFileStore softens its docstrings to acknowledge the
inherent probe-then-open TOCTOU window. On POSIX both read and write
now pass O_NOFOLLOW so the kernel refuses if the leaf segment becomes
a symlink between the probe and the open. Windows has no equivalent
flag; the limitation is documented.
- Tests cover: case preservation on list/search, ValueError on non-UTF-8
read at the store and tool layer, tool-layer string responses for
path-traversal and oversized-regex inputs, search-skip log output,
symlink rejection on delete/search/list, and symlinked intermediate
directory rejection.

* Address FileAccess nit comments: docstrings, enumerate, opt-in delete approval
- Expand FileSearchMatch/FileSearchResult.to_dict docstrings to explain why
the override is needed (__slots__ defeats the mixin's __dict__ iteration)
and why exclude/exclude_none are accepted-but-ignored (mixin signature
compatibility for callers like to_json).
- Use enumerate(lines, start=1) in _search_file_content so the +1 below is
no longer needed; rename loop variable to line_number for clarity.
- Add opt-in require_delete_approval: bool = False on FileAccessProvider.
When True, file_access_delete_file is registered with approval_mode
'always_require' so the host must approve every delete. Default False
preserves current behaviour and matches the .NET reference, but
deployments that want a safer-by-default posture can enable it.
- Add tests covering both delete approval modes.

* FileAccess: require delete approval by default
Flip the default for FileAccessProvider(require_delete_approval=...) from
False to True so destructive deletes are gated by host approval out of the
box. Callers that want the previous autonomous behaviour (which matches the
.NET reference) can pass require_delete_approval=False.
Tests updated accordingly.

Bumps the released 1.6.0 packages agent-framework, agent-framework-core, agent-framework-foundry, and agent-framework-openai to 1.7.0, with root continuing to exactly pin agent-framework-core[all]. Bumps the changed prerelease packages agent-framework-a2a, agent-framework-chatkit, agent-framework-declarative, agent-framework-devui, and agent-framework-foundry-hosting to the 260528 date stamp, raises core floors on the packages included in this release, raises Foundry's OpenAI floor alongside OpenAI, and raises ChatKit's openai-chatkit floor to the minimum version required by the current typed API usage. No beta cohort bump was applied; the absent mistal/mistral package was intentionally not bumped because no such package exists in this branch.

`OpenAIChatClient._inner_get_response()` reads `.headers` on the raw streaming
response returned by `client.responses.with_raw_response.create(stream=True)`
(and its three sibling call sites - retrieve-streaming, non-streaming create
and background retrieve) to surface the `x-ms-served-model` Azure header,
introduced in #5910.
When `azure-ai-projects>=2.1.0` experimental GenAI tracing is enabled
(`AZURE_EXPERIMENTAL_ENABLE_GENAI_TRACING=true`), the instrumentor wraps the
raw streaming response in an inline `AsyncStreamWrapper` that exposes
`.response` but not `.headers`. Reading `raw_create_response.headers` then
raises `AttributeError: 'AsyncStreamWrapper' object has no attribute 'headers'`,
which `FoundryChatClient` rethrows as a `ChatClientException` and breaks every
streaming call (workflows and free chat).
Fix: read the header dict via `getattr(raw_response, "headers", None)` at all
four call sites. `_extract_served_model()` already short-circuits on `None`,
so the served-model surfacing degrades gracefully (model stays the deployment
alias) instead of crashing when the response is wrapped by an instrumentor
that does not proxy `.headers`.
Regression test added:
`test_streaming_response_without_headers_attribute_does_not_crash`
simulates a stream wrapper that raises `AttributeError` on `.headers` and
asserts the stream still completes with the deployment alias as `update.model`.

- Track task_id, context_id, and task_state from all response payload types
- Validate context_id consistency (raise on mismatch)
- Auto-assign server-generated context_id when not set
- Only A2AAgentSession gets reference tracking (no state dict fallback)
- Plain AgentSession continues to work without reference tracking
- Add serialization support (to_dict/from_dict)
- Export via agent_framework.a2a and agent_framework_a2a

* fix: track context_id from message payloads in A2AAgentSession
Previously, context_id was only captured from task, status_update, and

but may lack task_id) were silently lost. This fix:
- Captures msg.context_id in the message handler
- Persists session state when either last_task_id or last_context_id is
present (not only when task_id is truthy)
- Only updates task_id/task_state when a task_id was actually returned
- Adds a test for message-only context_id tracking

Replace deprecated `asyncio.iscoroutinefunction()` with `inspect.iscoroutinefunction()`
to resolve Python 3.13+ deprecation warning.
Changes:
- Added `import inspect` to imports
- Replaced `asyncio.iscoroutinefunction(hook)` with `inspect.iscoroutinefunction(hook)` on line 126
- This makes the code consistent with other test methods in the same file (lines 201, 236)
The rest of the file already uses `inspect.iscoroutinefunction()` correctly, making
this change consistent with the existing codebase pattern.

* feat(foundry): add experimental to_prompt_agent converter
Adds `to_prompt_agent(agent)`, an experimental converter
(`ExperimentalFeature.TO_PROMPT_AGENT`) that turns an Agent Framework
`Agent` into a Foundry `PromptAgentDefinition` ready to publish via
`AIProjectClient.agents.create_version(...)`.
Behaviour:
* `agent.client` must be a `FoundryChatClient` (or subclass); otherwise
`TypeError` is raised. The model deployment name is lifted from the
bound client so the same Agent definition used for local runs can be
published as a hosted prompt agent without restating the model.
* Foundry SDK tool instances (from `FoundryChatClient.get_*_tool()`) are
passed through unchanged. AF `FunctionTool`s (and `@tool`-decorated
callables) are emitted as Foundry `FunctionTool` declarations.
* Local AF MCP tools cannot be expressed in a `PromptAgentDefinition`;
the converter raises `ValueError` and points at
`FoundryChatClient.get_mcp_tool()` for hosted MCP servers.
* The converter walks both `agent.default_options["tools"]` and
`agent.mcp_tools` because `normalize_tools()` splits local MCP off
into its own list.
Re-exported through the `agent_framework.foundry` lazy-loading namespace
(updates both `__init__.py` and the `__init__.pyi` type stub).
Adds a portable-agent sample showing the same `Agent` driven through
both `agent.run(...)` and `to_prompt_agent(agent)`, and a README section
covering the new converter.

* fix(foundry): address review comments on to_prompt_agent converter
* Construct `PromptAgentDefinition` `Tool` from a dict via `**tool_item`
unpacking rather than the positional Mapping constructor \u2014 cleaner and
matches the typical Pydantic / Azure SDK pattern.
* Drop the redundant `isinstance(mcp_tool, MCPTool)` guard in
`_convert_tools`; the parameter is already typed `Iterable[MCPTool]` so
the second `raise` was unreachable. The remaining single `raise`
fires for every entry as intended.

* fix(foundry): match Agent.__init__ model resolution in to_prompt_agent
* Read the model from `agent.default_options.get("model")` first,
falling back to `agent.client.model`. This mirrors the order
`Agent.__init__` uses (`_agents.py:740`) when assembling
default_options, so the model the agent runs with is the same model
the converter publishes \u2014 e.g. when the caller passes
`default_options={"model": "..."}` to override the bound client.
* Updated the missing-model error message to point at both the client
and the default_options paths.
* Added tests:
* tool-only agent with no `instructions` produces a definition
where `instructions` is `None` and is omitted from the dict
payload (`Agent.__init__` strips None values from default_options
before storing them).
* `default_options['model']` wins over the bound client's model.
* Fallback to client.model when default_options has no model.

* feat(foundry): add deploy_as_prompt_agent helper + samples
Adds `deploy_as_prompt_agent(agent)`, a convenience wrapper around
`to_prompt_agent` that reuses the bound FoundryChatClient's project
client to call `project_client.agents.create_version(...)`. Defaults
`agent_name` / `description` from `agent.name` / `agent.description`
so the Agent stays the single source of truth.
* Exposed from `agent_framework_foundry` and the lazy-loading
`agent_framework.foundry` namespace (including the .pyi stub).
* Marked experimental with the existing
`ExperimentalFeature.TO_PROMPT_AGENT` tag.
* Tests cover the happy path, name/description defaulting, explicit
override, no-name error, metadata + description forwarding, extra
kwargs passthrough, and the experimental metadata.
Samples:
* Renamed the existing sample to `creating_prompt_agents.py`, drops
'portable' wording, presents `deploy_as_prompt_agent` first as the
recommended path and `to_prompt_agent` + `AIProjectClient` as the
two-step alternative, and adds a cleanup step that deletes the
published agent so re-runs stay idempotent.
* New `using_prompt_agents.py` shows the end-to-end loop: deploy the
agent, connect to it with `FoundryAgent` passing the same local
`@tool` callable, run a query against the deployed prompt agent,
then clean up.
README updated to introduce `deploy_as_prompt_agent` as the
recommended path and link to both runnable samples.

(accepted as a keyword argument).
* default_options-sourced (with kwarg overrides):
temperature, top_p, string tool_choice
* kwarg-only Foundry knobs:
reasoning, text, structured_inputs, rai_config, ToolChoiceParam tool_choice

* refactor(foundry): single source of truth for prompt-agent options
Stop duplicating the generation-parameter surface between FoundryChatOptions
and to_prompt_agent. Translate every field with an Agent Framework equivalent
(temperature, top_p, tool_choice, reasoning, response_format/text/verbosity)
from agent.default_options via a new RawFoundryChatClient helper
_prepare_prompt_agent_options. Only Foundry-specific fields with no AF
equivalent — structured_inputs and rai_config — remain as keyword arguments
on to_prompt_agent.
- tool_choice is dropped when there are no tools (mirrors _prepare_options
semantics and avoids polluting tool-less prompt agents with Agent.__init__'s
'auto' default).
- response_format Pydantic models route through
openai.lib._parsing._responses.type_to_text_format_param; dict shapes go
through the existing _prepare_response_and_text_format helper.
- default_options is not mutated; text dict is defensively copied.

whose only consumer is the prompt-agent converter, while still serving as
the source of the request-path helper (_prepare_response_and_text_format)
that the converter reuses for dict-shaped response_format values.

* docs(python): codify GA terminology + post-run docs review
Add two pieces of guidance to python/AGENTS.md:
* Terminology - reserve 'GA' for hosted services; use 'released' or 'stable'
for Agent Framework code/features to match the feature-lifecycle stages.
* Maintaining Documentation - review AGENTS.md and skills at the end of every
run and update any guidance the conversation made stale; before adding a
new principle, ask the user to confirm it should be captured.
Also pulls in a docstring fix in foundry_prompt_agents.py that swaps the
stray 'GA' for 'released', applying the new terminology rule.
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* address PR review: strict=True default, Tool._deserialize dispatch, sample cleanup safety
- FunctionTool published as strict=True so the server-side schema validation
matches what the local FoundryAgent(tools=[same_callable]) dispatcher
enforces. AF FunctionTool has no 'strict' attribute, so the safer default
is used uniformly instead of silently downgrading to a permissive contract.
- _validate_mapping_tool now dispatches through ProjectsTool._deserialize so
dict-shaped tools rehydrate to the concrete subclass (FunctionTool,
WebSearchTool, ...) via the 'type' discriminator instead of returning a
generic Tool. Added a test that asserts isinstance(WebSearchTool) and a
new test for the function-typed dict path.
- foundry_prompt_agents.py sample now wraps credential + project client in
async with and the create_version / run flow in try/finally so a failure
on connect or run still deletes the published prompt agent rather than
leaving an orphaned, billable resource in the user's Foundry project.

* fix(ci): correct linkspector ignorePattern typo (./pulls -> ./pull)
GitHub PR URLs use the singular segment /pull/N (compare to /issues/N

anything as a result, so legitimately stale PR links (e.g. PRs deleted
from forks) surface as linkspector failures on unrelated PRs.
This is the same convention the './issues' rule above already follows.

* Add Python parity sample for invoking Foundry Toolbox tools from declarative workflows
* Python: address PR review on declarative toolbox sample
Two security fixes for PR #5933:
1. Add safe_mode flag to WorkflowFactory (default True) mirroring
AgentFactory. Gates =Env.* exposure inside DeclarativeWorkflowState
PowerFx symbols via _safe_mode_context, so workflow YAML loaded from
untrusted sources no longer leaks the host's full os.environ snapshot
into PowerFx evaluation. The flag is also forwarded to the
internally-constructed AgentFactory so inline agent definitions
follow the same policy.
2. Pin the invoke_foundry_toolbox_mcp sample's _client_provider to the
resolved toolbox endpoint. The bearer-authenticated httpx client is
now only returned when MCPToolInvocation.server_url matches the
toolbox URL case-insensitively; any other URL gets None (the default
unauthenticated path), preventing the Foundry AAD bearer token from
being attached to a mis-configured or injected server URL. Mirrors
the .NET sample's httpClientProvider guard.
The sample is updated to opt in to safe_mode=False because its YAML
intentionally uses =Env.FOUNDRY_TOOLBOX_* to keep configuration in env
vars under the developer's control.

* fix(core): point @experimental warnings at user code, not stdlib internals
Previously the wrappers installed by @experimental called warnings.warn
with a fixed stacklevel=3. ABCMeta inserts an extra abc.__new__ frame
when an experimental ABC is subclassed, so the warning landed inside
abc.py (or <frozen abc>:106 on modern CPython) instead of the user's
class Sub(...) line.
Resolve the user frame by walking inspect.currentframe(), skipping
frames whose module name is abc/functools/typing/contextlib (or
submodules), then emit via warnings.warn_explicit so the recorded
filename/lineno point at user code. Falls back to warnings.warn with
stacklevel=2 if no user frame is found. Module-name matching is used
because frozen stdlib modules report '<frozen abc>' as their filename.
Also install a one-line warnings.formatwarning specifically for
FeatureStageWarning so 'file:line: ExperimentalWarning: [ID] Name ...'
prints without the secondary source-snippet line. Other categories
delegate to the stdlib default formatter unchanged.
Added a regression test that subclasses an @experimental ABC inside
warnings.catch_warnings and asserts the recorded filename equals the
test file.

- Make _install_feature_stage_formatter idempotent: tag the installed
formatter with a marker attribute and short-circuit re-installation,
so re-imports/reloads don't wrap the formatter on top of itself.
Also expose the previous formatter via __wrapped__ for restoration.
- Avoid leaking frame references in _resolve_user_frame: capture data
into plain locals inside try and del frame/candidate in finally,
per CPython's guidance on inspect.currentframe usage.
- Drop redundant _WARNED_FEATURES.clear() in the new ABC subclass test
(the autouse fixture already handles it).

* feat(tools): add cross-OS LocalShellTool in new agent-framework-tools package
Introduces a safe, cross-OS local shell tool as the first citizen of a new
agent-framework-tools workspace package. Supports persistent (default) and
stateless modes across pwsh/powershell.exe/bash/sh, with policy denylist,
allowlist, approval gating, process-tree kill on timeout, output truncation,
and audit hooks. Integrates with existing provider get_shell_tool(func=...)
factories via FunctionTool kind='shell'.
See docs/decisions/0026-builtin-tools-local-shell.md for the full design.

* feat(tools): security hardening for LocalShellTool
Codifies what LocalShellTool does and does not defend against, and
delegates the security-relevant lifecycle primitive to a battle-tested
library instead of hand-rolled per-OS code.
Changes:
- Adopt psutil for cross-OS process-tree termination (executor + session).
Replaces hand-rolled taskkill/killpg with one canonical implementation.
- Resolve taskkill.exe to absolute %SystemRoot%\System32 path so PATH
poisoning cannot redirect us to an attacker-supplied binary.
- Reframe ShellPolicy docstring + ADR + README: denylist is a guardrail,
not a security boundary.
- Require acknowledge_unsafe=True to set approval_mode='never_require',
making the unsafe path explicitly opt-in with a self-documenting name.
- Add tests/test_security.py codifying named CVE-style cases. Defenses
we DO claim are asserted; non-defenses (denylist bypasses via
backslash insertion, variable expansion, interpreter escape, base64,
alternative tools, PowerShell-native verbs) are documented as
expected-to-pass tests so residual risk stays visible.
- Add Threat Model + Confidence Strategy sections to ADR 0026.

* feat(tools): add DockerShellTool sandboxed shell tier
Adds a container-backed shell executor as the recommended pattern for untrusted-input shell workflows. The container provides the security boundary (--network none, non-root user, --read-only, --cap-drop ALL, no-new-privileges, memory/pids limits, tmpfs /tmp), so approval gating is optional unlike LocalShellTool.
Also introduces a ShellExecutor Protocol so callers can plug in custom backends (Firecracker, SSH, WASI) without forking the framework.
Removes the planned HyperlightShellExecutor follow-up from ADR 0026: Hyperlight is a WASM code sandbox with no kernel/userland/shell binary, so a Hyperlight-backed shell is not viable. Docker is the realistic sandbox tier for shell.
Tests: 11 unit tests for argv builders + lifecycle (no Docker daemon required); 3 integration tests gated on is_docker_available().

* fix(tools): backport shell-tool fixes from .NET parity review
Applies the applicable subset of bug fixes accumulated during the
.NET shell-tool PR review (microsoft/agent-framework#5604) to the
Python shell tool.
A1 - Quote workdir safely in _maybe_reanchor
Previously _tool.py used double-quote interpolation when emitting
the cd/Set-Location prefix, which expanded $VAR, $(), and backticks
in the workdir path. A workdir containing shell metacharacters could
trigger arbitrary command execution before the user command ran.
Replaced with single-quote escaping helpers _quote_posix and
_quote_powershell that emit literal-string forms safe for both
hosts.
A5/A6 - Consolidate truncation to a single byte-aware helper
Extracted a shared truncate_head_tail / truncate_text_head_tail
helper in _truncate.py. The new implementation distributes odd
caps so head receives floor(cap/2) and tail receives ceil(cap/2)
bytes, matching the .NET round-9 fix and ensuring no input bytes
are silently dropped on the boundary.
_session.py previously truncated by Python str length while the
caller passed _max_output_bytes - the unit mismatch is now gone:
raw byte buffers go through truncate_head_tail and decoded text
goes through truncate_text_head_tail.
Unit tests added for the truncate and quote helpers.

* docs(tools): tone down narrative and overconfident comments in shell tool
The shell tool's docstrings and comments contained two patterns that
the .NET review pushed back on:
- Narrative framing about implementation history ("hard-won",
"we sidestep", "design inspiration: ...", competitor framework
name-drops in module docstrings).
- Overstated security guarantees ("battle-tested",
"reasonable for untrusted input", "recommended executor for any
agent that runs commands from untrusted input",
"destructive commands are blocked", "safe local shell tool",
"blocks shell injection").
Rewrites the affected docstrings and comments to describe what the
code does in neutral terms. Behaviour is unchanged.

* feat(tools): add ShellEnvironmentProvider for the Python shell tool
Ports the .NET ShellEnvironmentProvider as a Python ContextProvider
so agents using LocalShellTool or DockerShellTool can be primed with
an accurate description of the shell they're talking to (family,
version, OS, working directory, and which CLIs are available).
The provider runs probes through any ShellExecutor, caches the
resulting snapshot, and on every before_run extends the session
instructions with a markdown block describing the shell idiom to
use. A failed first probe leaves the cache empty so the next call
retries (no permanent poisoning).
Probe failures from a narrow set of expected error types
(ShellCommandError, ShellExecutionError, ShellTimeoutError, and
asyncio.TimeoutError from the per-probe timeout) are recorded as
None fields in the snapshot. Other exceptions propagate. Tool
names are validated against ^[A-Za-z0-9._-]+$ before being
interpolated into a probe command.
Includes 12 unit tests covering happy path, stderr fallback,
timeout handling, expected/unexpected exception paths, malicious
tool name rejection, case-insensitive deduplication, retry after
failure, concurrent first-callers sharing one probe, and the
default and custom formatter paths.

* docs(tools): document ShellEnvironmentProvider and finish comment cleanup
Add a README section introducing ShellEnvironmentProvider, soften two remaining overconfident security-boundary comments in _executor_base.py and the DockerShellTool class docstring, and add a sample (shell_with_environment_provider.py) that demonstrates the provider in stateless and persistent modes.

* refactor(tools): move shell samples to python/samples/02-agents/tools
The repository convention is to host samples under python/samples/ rather than inside the package directory. Move the two net-new shell samples (allow-list and environment-provider) to python/samples/02-agents/tools/ and drop the in-package samples/ directory; the existing top-level providers/openai/client_with_local_shell.py already covers the basic LocalShellTool walkthrough.

* test(tools): cover confine_workdir default and ShellResult.format_for_model
Two new tests in test_local_shell_tool.py exercise the default confine_workdir=True behaviour on POSIX and PowerShell, asserting that 'cd' inside one persistent-mode call does not leak into the next. A new test_shell_result.py module provides direct unit coverage for every conditional branch of ShellResult.format_for_model (stdout, truncated, stderr, timed_out, exit_code) so regressions in the LLM-facing format are caught immediately.

* fix(tools): address PR #5664 review feedback
- _tool.py: detect PowerShell via is_powershell() helper instead of basename string match
- _environment.py: use public ContextProvider import (no private _ prefix)
- _session.py: trim _stdout_buf/_stderr_buf after copying to avoid unbounded retention across calls
- _docker.py: short-circuit start()/close() in stateless mode; add configurable shell kwarg (default bash, e.g. 'sh' for alpine)
- tests: parenthesized multi-line assert; alpine integration tests now pass shell='sh'

* fix(tools): satisfy CI quality gates
- pyupgrade: drop quoted self-class refs in __aenter__/method annotations
- ruff format: reflow long lines per workspace style
- pyright: assert psutil non-None in optional-import branch; lowercase mutable module globals; annotate _approval_mode as Literal so tool() Literal-typed kwarg is accepted; add ... body to ShellExecutor.run protocol; remove unused deprecated _kill_tree wrapper
- tests: skip docker integration tests on win32 (Windows containers don't support --read-only / alpine images)

* Remove DEFAULT_DENYLIST; document single-session ownership; fix bandit findings
Mirrors the .NET PR #5604 cleanup:
- Remove DEFAULT_DENYLIST from ShellPolicy. ShellPolicy() now ships with an empty deny-list; operators opt into site-specific patterns explicitly. No major agent framework uses regex matching as a primary security control; AutoGen v2 removed theirs. Approval gating + sandbox tier remain the real boundaries.
- Rewrite module / class docstrings to frame ShellPolicy as a UX pre-filter, not a security control.
- Add Single-session ownership paragraphs to ShellExecutor, ShellSession, LocalShellTool, and DockerShellTool: a persistent-mode tool is owned by exactly one conversation / agent session; do not share across users or concurrent conversations.
- Tests now supply explicit deny patterns instead of relying on a default.
- Address Pre-commit Hooks (bandit) CI failures: convert internal-invariant asserts to explicit RuntimeError, annotate intentional subprocess/shell usage with # nosec, document container-internal /tmp paths.

* Address PR #5664 round-2 review feedback
Deny-list documentation drift:
- README and the OpenAI/local-shell sample no longer claim a built-in deny-list of destructive commands. ShellPolicy is described as an optional, operator-supplied UX pre-filter; the real boundaries remain approval gating and the sandbox tier.
Behavioural fixes called out in review:
- ShellPolicy.evaluate() now denies empty / whitespace-only commands explicitly instead of returning allow with no rationale.
- truncate_head_tail() raises ValueError for cap <= 0 instead of silently returning the full input with truncated=False, which previously could defeat output-capping in callers that mis-configured the budget.
- LocalShellTool.as_function() / DockerShellTool.as_function() return the ShellCommandError text directly so the model sees a single, non-redundant 'Command rejected by policy: …' message instead of the prior duplicated 'Command blocked by policy: Command rejected …' wrapping.
- ShellSession POSIX sentinel trailer now snapshots and restores the prior errexit (set -e) state around the trailer, so a user 'set -e' in the persistent shell is no longer permanently disabled by the next run().
Tests:
- New test_shell_parse_rc.py covers the full _parse_rc() edge-case surface (zero, positive, negative, CRLF, no newline, missing prefix, empty input, non-digits, trailing garbage, partial digits).
- test_policy.py asserts the new empty-command deny.
- test_shell_truncate_and_quote.py asserts ValueError for cap=0 and cap<0.

* Address PR review feedback for shell tool
- _resolve.py: reject empty/whitespace shell override string
- _tool.py / _docker.py: mode-aware default tool description (persistent vs stateless)
- _tool.py: fix misleading workdir docstring (re-anchor, not blocking)
- _types.py: emit stream-agnostic [output truncated] marker
- _policy.py: declare _denies/_allows as dataclass fields
- _environment.py: use $(pwd) instead of $PWD in POSIX probe
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* Address PR review feedback: shell override flag + probe timeout safety
- _resolve.py: in stateless mode, ensure shell overrides end with -c/-Command so commands aren't misinterpreted as script-file paths.
- ShellExecutor.run / LocalShellTool.run / DockerShellTool.run now accept an optional imeout kwarg; ShellEnvironmentProvider drops the outer asyncio.wait_for and lets the executor enforce the probe timeout internally, so cancellation no longer risks leaving a hung subprocess or corrupted session.
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* Address review feedback: docker isolation + lifecycle robustness
- pyproject.toml: bump agent-framework-core minimum from 1.2.0 to 1.2.2 to align with the rest of the workspace.
- _docker.py: validate extra_run_args at construction time and reject flags that would dismantle the isolation defaults (--privileged, --cap-add, --security-opt, --network/--net, -v/--volume/--mount, --device, --pid, --ipc, --userns, --user, --read-only, --tmpfs, --add-host, --gpus, --cgroupns, --device-cgroup-rule); also documented the warning on the docstring.
- _docker._stop_container: retry docker rm -f once and log a warning/error when it does not succeed, so operators can audit leaked containers instead of getting a silent success.
- _docker._run_stateless timeout path: fall back to docker rm -f when docker kill fails or times out (--rm only reaps on clean exit), and log instead of silently swallowing communicate() errors.
