Python: correct MCP tool argument filtering documentation (#7801)
* Python: correct MCP tool argument filtering documentation The documentation for MCPTool's outbound argument filtering did not match its behavior. The comment on _prepare_call_kwargs stated that framework runtime kwargs are "stripped so it is never forwarded to the MCP server", and packages/core/AGENTS.md repeated the same claim. In practice, runtime kwargs (FunctionInvocationContext.kwargs, seeded from function_invocation_kwargs) are merged with the model-supplied arguments in _call_tool_with_runtime_kwargs before the filter runs, so provenance is no longer distinguishable at that point. The allowlist is built from the tool's declared inputSchema.properties as advertised by the server, plus names opted in through additional_tool_argument_names. A runtime kwarg is therefore forwarded whenever the server declares a property of the same name, without the model supplying it. Update the comments, docstrings and docs to describe the actual rule, and point each transport at its appropriate channel for values that should not become tool arguments (env for stdio, header_provider for streamable HTTP). Also narrow the docstring of test_call_tool_forwards_only_declared_arguments, which claimed more than it asserts (it covers undeclared names only), and add a companion test pinning the declared-name behavior so the documented rule stays verifiable. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Python: address review feedback on MCP argument filtering docs Corrects and tightens the documentation added in the previous commit. - header_provider does not withhold values from the outbound argument filter; it reads the runtime kwargs without consuming them. The earlier wording recommended it as a way to keep a value out of tool arguments, which is wrong. Replaced in four places with the pattern that does work: source the credential outside function_invocation_kwargs, for example by reading a ContextVar inside the provider, which still allows a different value per request. - Note the _meta key and the framework denylist as exceptions wherever the docs say server-declared names are forwarded. - Rework test_call_tool_forwards_runtime_kwargs_the_server_declares to invoke the generated FunctionTool with a FunctionInvocationContext, so it exercises the real runtime-kwargs path instead of calling call_tool directly. Verified by mutation: removing the merge in _call_tool_with_runtime_kwargs now fails the test. - Add a test covering the recommended ContextVar pattern. - Condense the transport docstring notes, which had grown into three near-duplicate blocks.

Python: [BREAKING] Require building functional workflow instances (#7521)
* Harden functional workflow continuation authority Use a versioned opaque single-use token on WorkflowRunResult, validate it before request correlation, consume it immediately before replayed user code, and rotate it on each pause. Carry the same explicit authority through streaming and non-streaming FunctionalWorkflowAgent responses. Files changed: functional workflow/runtime result APIs, functional HITL regression tests, core agent guidance, and the functional HITL sample. Next iteration: enforce pending-state overlap and token-authorized abandonment, then document and test checkpoint authorization boundaries. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Enforce one pending functional continuation Reject fresh messages and checkpoint restores while an in-memory continuation is pending. Add token-authorized abandonment on FunctionalWorkflow and FunctionalWorkflowAgent, and clear retained replay state atomically when authority is consumed while preserving the active message for token rotation and checkpoints. Files changed: functional workflow runtime and agent adapter, functional lifecycle regression tests, and core workflow guidance. Next iteration: preserve and document authorized checkpoint continuation boundaries. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Preserve authorized functional checkpoint continuation Treat checkpoint restore as a host- and storage-authorized path independent of process-local continuation tokens, and issue fresh authority whenever restored execution pauses again. Cover default and per-run storage, deterministic and custom request IDs, token rotation, and checkpoint-plus-response restore. Files changed: functional workflow and checkpoint interface guidance, functional checkpoint lifecycle tests, the functional HITL sample, and core workflow guidance. Next iteration: run the final repository-wide Python validation gates. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Validate Python continuation hardening Run the complete Python workspace checks, aggregate coverage suite, repository hooks, and core package build from the final combined worktree. Keep the validation iteration code-neutral because all gates pass without corrective changes. Files changed: none; this commit records the final validation gate. Blockers: none. Next iteration: no remaining AFK tasks. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Handle functional checkpoint continuation failures Publish retained continuation state only after checkpoint persistence succeeds, and cover reuse after a transient save failure.

This aligns functional workflows with the graph definition/build lifecycle and prevents module-level decorated definitions from retaining caller state. Move checkpoint configuration to build(), export the definition type, migrate samples, and cover isolated built instances.

Python: Support archive-type MCP skills (source, toolbox, sample) (#7121)
* Python: Support archive-type MCP skills in MCPSkillsSource Add `archive`-type skill support to `MCPSkillsSource` so an MCP server can advertise packaged skills (ZIP / TAR / gzip-compressed TAR) that are downloaded, safely unpacked to a local directory, and served like file-based skills, while keeping the guarantee that MCP-delivered scripts are never executed. - Dispatch `skill://index.json` entries by `type`: `skill-md` (existing, fetched on demand) and `archive` (new). Unknown types are skipped. - `_ArchiveEntryLoader` downloads, extracts, and prunes archive skills and delegates discovery to an internal `FileSkillsSource` created with no script extensions and no runner, so bundled scripts surface as read-only resources only. - Hardened stdlib extraction: path-traversal (zip-slip) guard, non-regular TAR member skipping, and file-count / uncompressed-size / download-size limits. - Configure via `archive_*` constructor kwargs (no options object, per Python conventions); use `CachingSkillsSource` for refresh rather than a source level refresh interval. - Fix `FileSkillsSource` to treat `None` extensions as "use defaults" and an empty tuple as "discover none" (an empty tuple previously fell back to defaults). Port of .NET PR #6631.

This matches the existing failure model used by `_try_read_index` and `MCPSkill.get_resource`, and avoids a failed `CachingSkillsSource` refresh overwriting a previously cached list with a partial result. Add tests asserting archive-download INTERNAL_ERROR and ConnectionError propagate out of `get_skills`.

Only explicitly-set options are forwarded so unset ones keep the MCPSkillsSource defaults. This lets a hosted toolbox agent redirect archive extraction to a writable directory (the default is under the cwd, which may be read-only in a container). - Add unit tests covering default (no options forwarded) and override forwarding. - Update the 12_foundry_toolbox_mcp_skills sample to demonstrate all three progressive-disclosure stages with an archive skill: escalation-policy now ships a references/refund-matrix.md resource and is uploaded as a ZIP archive; main.py disables load_skill and read_skill_resource approval and points archive extraction at a temp directory. README, toolbox.yaml, and ignore files updated accordingly.

The raise propagates to `_ArchiveEntryLoader._build_skill`, which already skips the skill on error. - Update tests: traversal cases now assert a raise, and add an end-to-end test that a zip-slip archive drops the whole skill.

Compose caching in as_skills_provider() instead: wrap the context-independent _FoundryToolboxSkillsSource in DeduplicatingSkillsSource(CachingSkillsSource(...)). Add a cache_refresh_interval param, fix the docstring, and add tests covering cached, disabled, and refresh-interval behavior. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Copilot-Session: 84150ec4-6f7c-4ef8-b9fb-12fa11652773 * Clarify caller-invariant skill-set wording in as_skills_provider docs Emphasize that the toolbox advertises the same skill set to every caller (the per-request call-id governs execution/authorization, not which skills are listed) rather than leaning on 'ignores SkillsSourceContext'. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Copilot-Session: 84150ec4-6f7c-4ef8-b9fb-12fa11652773 * Make MCP skills reconnect-safe via session_provider Cached MCPSkill objects captured the MCP ClientSession at construction, so after a FoundryToolbox reconnect (which replaces its session) load_skill and read_skill_resource would fail against the closed session. This regressed once as_skills_provider() started caching discovery by default. Add an optional session_provider callable to MCPSkillsSource and MCPSkill (exactly one of client or session_provider). When supplied, the session is resolved on every fetch, mirroring how MCPTool resolves self.session live at call time. _FoundryToolboxSkillsSource now passes a provider that returns the toolbox's current session, so cached skills always use the live session. The fixed client= path is unchanged and backward-compatible. Update core tests, foundry_hosting tests, and core AGENTS.md.

Python: feat: cross-session origin attribution on context messages (#7041)
* Python: feat: cross-session origin attribution on context messages Add an optional origin_session_id parameter to SessionContext.extend_messages that propagates into the existing _attribution payload on Message.additional_properties. Downstream context observers can use it to detect when a provider injects content stored under a different session than the requesting one. Populate the field from the harness memory consolidation pipeline (_harness/_memory.py) when injected topics include contributions from sessions other than the current one. Add a self-contained sample observer under samples/02-agents/context_providers/cross_session_observer.py demonstrating how to subscribe to the signal. Backward-compatible: omitting the parameter preserves the existing attribution shape exactly. Tests added in test_sessions.py and test_harness_memory.py cover the new parameter, the harness cross-session case, and the same-session case. Motivated by Dai et al., Stateful Agent Backdoor (arXiv:2605.06158, May 2026), which specifically surveys MAF in section 6.1 / Table 10. See #5914 for design discussion. Surfaced during independent audit conducted by @finnoybu (Ken Tannenbaum, AEGIS Initiative); [MEDIUM, python/packages/core]. * Address cross-session attribution review feedback * Address follow-up review feedback * Address follow-up review comments * Address origin attribution review feedback --------- Co-authored-by: finnoybu <21694570+finnoybu@users.noreply.github.com> |

Python: Add refresh_interval (TTL) to CachingSkillsSource (#6977)
* Python: Add refresh_interval (TTL) to CachingSkillsSource Port .NET's CachingAgentSkillsSourceOptions.RefreshInterval to the Python skills cache. Previously CachingSkillsSource cached a source's skill list indefinitely (only clearing on a failed fetch), so callers had no built-in way to periodically re-discover skills whose backing source changes at runtime (notably MCPSkillsSource over the network). CachingSkillsSource now accepts an optional refresh_interval (timedelta): a cached list older than the interval is treated as stale and re-fetched on the next call. When None (default) the cache never expires, so existing behavior is unchanged. Freshness is measured with a monotonic clock via a monkeypatchable _monotonic() helper. SkillsProvider.__init__ and from_paths expose a cache_refresh_interval kwarg threaded into the built-in cache. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Python: Address review feedback on CachingSkillsSource refresh_interval - from_paths: do not forward cache_refresh_interval when disable_caching=True, matching the docstring and avoiding a TypeError for legacy subclass __init__ signatures. - Correct docstring/AGENTS.md wording: a failed fetch does not update the cache (initial failure leaves it empty; a refresh failure keeps the prior list), rather than "resetting"/"leaving empty" in all cases. - Fix test typing: narrow provider._source via isinstance before accessing inner_source/_refresh_interval so ty/zuban/mypy/pyright all resolve them. - Add regression tests for disable_caching + interval and legacy-subclass paths. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Python: Do not forward cache_refresh_interval from from_paths into __init__ The refresh interval is already baked into the composed CachingSkillsSource that from_paths builds, and __init__ leaves a caller-supplied source un-wrapped, so forwarding cache_refresh_interval into cls(...) was a no-op for caching behavior while breaking legacy subclasses whose __init__ predates the kwarg (with caching enabled or disabled). Remove the forwarding entirely. Strengthen the regression test to cover the real break: a legacy subclass calling from_paths(paths, cache_refresh_interval=...) with caching enabled must not raise and the composed source still carries the interval. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Python: Drop _monotonic wrapper; call time.monotonic() directly Address review feedback: remove the _monotonic() helper that existed only to aid testing.

Add a small _NamedMockAgent subclass for tests needing distinct agent names, and drop now-unnecessary attr-defined ignores. - Use cast(SupportsAgentRun, ...) in foundry_hosting tests, which have no shared mock infrastructure. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Python: Make SkillsProvider caching safe-by-default; clarify context docstrings Address PR review comments: - Do not auto-wrap a caller-supplied SkillsSource in the provider's default CachingSkillsSource. A shared, unkeyed cache around a context-aware source replays the first invocation's skills for later SkillsSourceContexts, leaking skills across agents/tenants. Default caching now applies only to the built-in, context-independent file/in-memory leaf sources (Deduplicating(Caching(leaf))), matching the .NET provider. Callers who want caching on a custom pipeline compose CachingSkillsSource (optionally with a cache_isolation_key_selector) themselves. disable_caching now only affects the built-in leaves. Adds a leak-prevention test. - Reword the misleading "Unused by this source" context docstrings on the File/InMemory/MCP sources: the param is part of the get_skills contract; these sources just return the same skills regardless of context.

Python: Add AgentLoopMiddleware for re-running agents in a loop (#6174)
* Python: Add AgentLoopMiddleware for re-running agents in a loop Add `AgentLoopMiddleware`, an `AgentMiddleware` that re-runs the wrapped agent in a loop. A single configurable class covers three common patterns, each with a convenience classmethod factory: - Ralph loop (`.ralph(...)`): no exit criteria, with feedback tracking (`record_feedback`/`progress`), progress injection (`inject_progress`), optional fresh context per iteration (`fresh_context`), and an early-stop completion signal (`is_complete`). - Predicate (`.with_predicate(...)`): loop while a `should_continue` callable returns True (e.g. paired with `todos_remaining`/`background_tasks_running`). - Judge (`.with_judge(...)`): a second chat client decides whether the original request was answered, using a `JudgeVerdict` structured-output response. The loop also auto-resolves pending function-approval / user-input requests via an `on_approval_request` callable (bounded by `max_approval_rounds`), and the next iteration's input is controlled by `next_message`. Supports both streaming and non-streaming runs. Exports `AgentLoopMiddleware`, `JudgeVerdict`, `todos_remaining`, and `background_tasks_running`. Adds tests, a sample, and docs. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Python: Refine AgentLoopMiddleware API and sample - with_judge: add criteria list with {{criteria}} templating into judge instructions plus an agent-side instruction; add fresh_context, additional judge feedback relay; default judge max_iterations. - should_continue is now required and positional; supports (bool, str|None) feedback tuples surfaced to next_message/record_feedback via feedback kwarg. - Judge forwards full multi-modal request and response messages. - Default max_iterations=10 (explicit None = unbounded); removed is_complete and Ralph terminology; ShouldContinueResult is a real TypeAlias. - Sample: stream all loops, print iteration counts via injected user-block boundaries (robust to function calling), <role>: content formatting, per-method expected output, and a looping todo sample. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Python: Fix CI checks for AgentLoopMiddleware - Resolve pyright errors in _loop.py: drop the always-true final_result None check (the while loop always assigns it) and cast finish_reason to the AgentResponse constructor's expected type. - Apply pyupgrade --py310-plus: import TypeAlias from typing. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Python: Resolve mypy/pyright disagreement on finish_reason pyright infers AgentResponse.finish_reason as including str and rejects the direct assignment, while mypy considers a cast redundant.

Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Python: Add todo+judge AgentLoopMiddleware sample Add a second AgentLoopMiddleware sample that composes two criteria in one should_continue predicate: a TodoProvider check (evaluated first) and a report-style judge chat client (evaluated once todos are complete) that grades the assembled report against shared requirements.

Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Python: Compose todo+judge loops as two middleware Rework the todo+judge sample to compose two AgentLoopMiddleware on the agent itself (middleware=[judge_loop, todo_loop]) instead of a single hand-written predicate. The inner todos_remaining loop drafts the report todo-by-todo and the outer with_judge loop re-runs it until an editor chat client judges the report publication-ready, reusing the built-in helpers. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Reset session for fresh_context loops via snapshot/restore AgentLoopMiddleware.fresh_context previously only reset context.messages, so with an attached session each iteration still reloaded the local transcript or re-threaded the service-side conversation id and the model saw the accumulated history. Snapshot the session once before the loop (via to_dict) and restore it (from_dict + field copy) between iterations, so every pass starts from the pre-loop baseline. The final iteration's pass is persisted (no restore after the terminating iteration), so a subsequent agent.run continues from there. Removed the obsolete warning, updated docstrings and core AGENTS.md, and added tests: a snapshot/restore round-trip, a session-reset streaming x fresh_context x inject_progress x store matrix across multiple runs and loop iterations, and response_format parsing across the loop.

Python: [BREAKING] Add sampling guardrails to MCP tools (#6413)
* Add sampling guardrails to MCP tools Add approval, token, and request-count controls to the MCP sampling callback used when an MCPTool is configured with a chat client. - Add `sampling_approval_callback`, `sampling_max_tokens`, and `sampling_max_requests` parameters to `MCPTool` and its `MCPStdioTool`, `MCPStreamableHTTPTool`, and `MCPWebsocketTool` subclasses, positioned directly after `client`. - Gate each server-initiated `sampling/createMessage` request behind the approval callback, which denies by default when no callback is provided. - Clamp the requested `maxTokens` to `sampling_max_tokens` and enforce a per-session request count via `sampling_max_requests`. - Log incoming sampling requests at WARNING level (counts only). - Export `SamplingApprovalCallback` from the public API. - Add tests, a sample, and documentation updates.

Python: Filter MCP tool kwargs to declared params via allowlist (#6399)
* Filter MCP tool kwargs to declared params via allowlist Previously MCPTool combined framework runtime kwargs (from FunctionInvocationContext.kwargs) with the LLM-supplied arguments and stripped only a hardcoded denylist of known framework keys before forwarding to the MCP server. Any new framework-injected kwarg leaked to the server unless the denylist was updated. Switch to an allowlist built from each tool's declared parameters (inputSchema.properties). Only declared params are forwarded; everything else is stripped. Add an `additional_tool_argument_names` constructor argument so users can opt extra names back in, globally (Sequence[str]) and/or per remote tool name (Mapping with reserved "*" global key). The existing denylist is kept as a safety net for framework-named params a server declares in its schema; explicitly opted-in extras always win. The reserved _meta handling is unchanged.

* 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.

Python: Adding AgentFileStore and FileAccessProvider to support file access operations. (#6099)
* 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. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Fix mypy redundant-cast in FileSearchResult.from_dict Use cast(list[object], ...) instead of cast(list[Any], ...) so the cast represents a real type change (lists are invariant) and is no longer flagged by mypy as redundant, while still satisfying pyright's reportUnknownVariableType. Matches the existing pattern in _memory.py. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * 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. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * 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. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * 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. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * 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. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * 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.

Python: Improve the handling of intermediate outputs for workflows and orchestrations (#5623)
* Improve the handling of intermediate outputs for workflows and orchestrations
* Address PR review feedback on intermediate output forwarding
- Switch workflow.as_agent() forwarding to an explicit allowlist of {output,
intermediate, data, request_info} so orchestration-internal events
(group_chat, handoff_sent, magentic_orchestrator) stay inside the workflow
instead of leaking into agent responses via str(data) coercion.
- Stop raising on intermediate AgentResponseUpdate in non-streaming run();
surface the partial as a Message with text_reasoning content. The defensive
raise still applies to terminal output events, where Update payloads would
corrupt message ordering.
- Extend the DevUI workflow-event mapper so intermediate yields wrapping
plain strings, Messages, and list[Message] render as visible output items
instead of generic completed-trace events.
- Add orchestration coverage for GroupChat, Handoff, and Magentic builders
(default vs intermediate_outputs=True; structural where end-to-end is heavy).
* Lift output-designation policy into a value type
Replace the ``Workflow._output_executors`` list and the
``RunnerContext.should_label_as_intermediate`` Protocol method with a single
immutable ``OutputDesignation`` value type owned by ``Workflow``. Thread the
designation as a parameter through the existing call chain (Runner ->
EdgeRunner -> Executor -> WorkflowContext) so ``yield_output`` consults the
threaded snapshot directly rather than calling back into the runner context.
Removes the ``InProcRunnerContext._workflow`` back-reference and the
``WorkflowBuilder.build()`` assignment that wired it up. Adds the public
predicate ``Workflow.is_terminal_executor(executor_id)`` for external
observers; ``OutputDesignation`` itself stays package-internal.
Key decisions
- ``OutputDesignation.designated`` is ``frozenset[str] | None`` -- ``None``
preserves legacy "every yield is type='output'" behavior, any frozenset
(including empty) opts into strict mode. The ``DeprecationWarning`` for
legacy mode at build time is unchanged.
- ``output_designation`` is an optional parameter on ``Runner``,
``EdgeRunner.send_message``, ``EdgeRunner._execute_on_target``,
``Executor.execute``, ``Executor._create_context_for_handler``, and
``WorkflowContext.__init__``. Each defaults to legacy ``OutputDesignation()``
so direct callers (Azure Functions ``CapturingRunnerContext``,
``test_runner`` recording fixtures) keep working without ceremony.
- The workflow-level filter in ``_run_core`` reads ``self._output_designation``
live, preserving today's semantics where mutating the designation after
build still affects subsequent runs (used by two existing tests).
- ``Workflow.to_dict()`` continues to emit ``"output_executors":
list[str] | None`` (sorted from the frozenset). Checkpoint format unchanged.
Files changed
- _workflow.py: add ``OutputDesignation`` dataclass; replace
``_output_executors`` with ``_output_designation``; add
``is_terminal_executor``; delete ``_should_yield_output_event``.
- _runner_context.py: drop ``should_label_as_intermediate`` Protocol method
and ``InProcRunnerContext`` impl; drop ``_workflow`` back-reference.
- _workflow_builder.py: remove ``context._workflow = workflow`` assignment.
- _runner.py, _edge_runner.py, _executor.py, _workflow_context.py: thread
``output_designation`` parameter through the call chain.
- tests/workflow/test_output_designation.py (new): three-state coverage of
the value type plus the public predicate delegation.
- tests/workflow/test_workflow_builder.py, test_validation.py,
test_workflow.py, test_runner.py and
orchestrations/tests/test_orchestration_intermediate_vs_terminal.py:
switch probes from ``_output_executors`` set checks to
``get_output_executors`` / ``is_terminal_executor``; update two
post-build mutation tests to set ``_output_designation`` instead.
Verification
- core/tests/workflow/, orchestrations/tests/, azurefunctions/tests/:
1119 passed, 42 skipped, 2 xfailed.
- ``uv run poe lint``: clean.
- ``uv run poe typing``: only the pre-existing
``_AGENT_FORWARDED_EVENT_TYPES`` pyright warning from 394bcd607 remains.
Notes for next iteration
- The builder's own ``_output_executors`` attribute (``list[Executor |
SupportsAgentRun]``) is intentionally untouched; the issue scoped the
rename to the workflow attribute.
- Adjacent review candidates (twin ``WorkflowAgent`` translators,
``_AGENT_FORWARDED_EVENT_TYPES`` kind classifier,
``_event_origin_context`` ContextVar removal, ``WorkflowEvent`` ADT
split, legacy-mode removal) remain out of scope.
* Add explicit workflow output designation
Key decisions
- Extend the internal OutputDesignation value type from terminal-only membership to output/intermediate/hidden classification. Legacy mode remains outputs=None, so workflows built without output_executors or intermediate_executors still label every yield_output as type='output'.
- WorkflowBuilder now accepts intermediate_executors. Providing either designation enters explicit mode; output executors emit output, intermediate executors emit intermediate, and unlisted yield_output payloads are hidden from caller-facing events while remaining in executor_completed data.
- Empty explicit designation, duplicate entries, overlaps, unknown executors, and designated executors without workflow output annotations fail build validation. Existing orchestration builders pass intermediate-capable participants through intermediate_executors to preserve current intermediate_outputs behavior until participant-oriented designation lands.

- Slice 4 should tighten workflow.as_agent() mapping for hidden emissions and streaming-only update payloads; Slice 5 should replace orchestration intermediate_outputs with participant-oriented designation.
* Tighten workflow-as-agent output mapping
Key decisions
- Treat AgentResponseUpdate as a streaming-only payload across the workflow.as_agent() adapter, so non-streaming agent runs now reject both terminal output and intermediate workflow events carrying updates.
- Keep streaming classification behavior explicit: terminal update payloads remain normal text content, while intermediate update payloads are rewritten to text_reasoning content.
- Add explicit-mode coverage proving hidden yield_output emissions do not appear in non-streaming AgentResponse messages or streaming AgentResponseUpdate chunks.

* Add orchestration participant output designation
Key decisions
- Replace orchestration intermediate_outputs with participant-oriented output_participants and intermediate_participants across Sequential, Concurrent, GroupChat, Magentic, and Handoff builders.
- Keep synthetic final executors terminal by default for Concurrent, GroupChat, and Magentic; keep Sequential's final participant terminal by default; keep Handoff participants terminal by default.

- uv run poe typing still fails only on the pre-existing packages/core/agent_framework/_workflows/_agent.py _AGENT_FORWARDED_EVENT_TYPES private-use pyright error.
* Migrate samples to explicit output designation
Key decisions
- Replace sample usage of the removed orchestration intermediate_outputs boolean with participant-oriented intermediate_participants designation.
- Update raw workflow guidance to show output_executors together with intermediate_executors, and document that unlisted yields are hidden in explicit designation mode.
- Keep orchestration final outputs terminal while streaming designated participant responses as intermediate progress, including workflow.as_agent() samples where intermediates map to text_reasoning content.
- Refresh workflow and orchestration README guidance plus the changelog reference so public docs no longer point users at intermediate_outputs.

* Render DevUI intermediate workflow outputs
Key decisions
- Preserve workflow output designation metadata on visible DevUI output messages and text deltas so intermediate/data emissions remain distinguishable from terminal output.
- Render intermediate workflow message items in the execution timeline using executor metadata, while excluding them from the final workflow result aggregation.
- Keep terminal output message rendering unchanged and retain legacy data events on the intermediate compatibility path.

* Fix mypy
* Clarify orchestration participant output config
* Rename participant output kwargs for clarity
output_participants -> final_output_from, intermediate_participants ->
intermediate_output_from. The old names read like categories of
participant; the new names make it clear the kwarg designates which
participants' outputs surface as final vs. intermediate events.
* Rename core workflow output kwargs with deprecation shim
Adds final_output_from / intermediate_output_from as canonical kwargs on
Workflow and WorkflowBuilder. Old output_executors / intermediate_executors
kwargs continue to work but emit DeprecationWarning via a shared coalesce
helper that also rejects supplying both. Wire-format keys in to_dict()
stay as output_executors / intermediate_executors so checkpoint
compatibility is preserved.
Internal call sites in orchestrations and samples updated to the new
names so users following sample code learn the canonical vocabulary;
legacy callers still work with a one-shot warning.
* Suppress pyright reportPrivateUsage on cross-module sentinel import
* Update docstrings
* Propagate sub-workflow intermediate outputs, fix handoff/sequential intermediate-only designation, and shore up tests, sample, and docstrings around the intermediate output contract.
* Add canonical workflow output_from selection
Key decisions:\n- Make output_from the canonical workflow-output allow-list and keep output_executors/final_output_from as deprecated compatibility aliases.\n- Treat empty output_from/intermediate_output_from lists as explicit selections and keep validation responsible for empty, duplicate, overlap, and unknown selections.\n- Remove the branch-only public intermediate_executors WorkflowBuilder kwarg while preserving legacy wire keys in to_dict().\n\nFiles changed:\n- packages/core/agent_framework/_workflows/_workflow.py\n- packages/core/agent_framework/_workflows/_workflow_builder.py\n- packages/core/agent_framework/_workflows/_workflow_context.py\n- packages/core/agent_framework/_workflows/_agent.py\n- packages/core/agent_framework/_workflows/_agent_executor.py\n- packages/core/tests/workflow/* output-selection coverage updates\n- packages/core/AGENTS.md\n- issues/done/001-canonical-list-based-output-selection.md\n\nBlockers/notes:\n- Orchestration builders still pass final_output_from internally; follow-up issue 004 should migrate them to output_from.\n- Legacy omitted-selection behavior and explicit all/all_other literals are left for issues 002 and 003.
* Add explicit all workflow output selection
Key decisions:
- Treat output_from='all' as an explicit workflow-output selection sentinel and expand it at build time to executors with declared workflow output types.
- Keep omitted output selections in legacy all-output mode with a deprecation warning that names output_from and intermediate_output_from and points to output_from='all'.
- Reject intermediate_output_from='all' at construction because the all-output literal is output-only for this issue.

- packages/core/agent_framework/_workflows/_workflow_builder.py
- packages/core/tests/workflow/test_output_executors_contract.py
- issues/done/002-explicit-all-output-and-legacy-migration.md
Blockers/notes:
- all_other intermediate-output selection remains for issue 003.
- Workflow-as-agent/orchestration parity remains for issue 004.
* Add all-other intermediate output selection
Key decisions:
- Treat intermediate_output_from='all_other' as an explicit intermediate-output selection sentinel and expand it at build time after the workflow graph is complete.
- Expand all_other to output-capable executors not selected by output_from; omitted or empty output_from selects no workflow outputs, while output_from='all' leaves an empty intermediate selection.
- Keep output_from='all_other' invalid so all_other remains intermediate-output-only and runtime classification still receives concrete executor-id sets.

- packages/core/tests/workflow/test_output_executors_contract.py
- issues/done/003-all-other-intermediate-output-selection.md
Blockers/notes:
- Workflow-as-agent and orchestration parity remains for issue 004.
- Full documentation updates remain for issue 005.
* Add orchestration output selection parity
Key decisions:
- Expose output_from on sequential, concurrent, group chat, handoff, and magentic builders while keeping final_output_from as a deprecated compatibility alias.
- Resolve orchestration participant selections through the same explicit rules as workflows: output_from='all', intermediate_output_from='all_other', hidden unselected participant payloads, and overlap/duplicate/unknown/invalid-literal validation.
- Continue preserving documented orchestration defaults by always designating each pattern's terminal internal executor where applicable.

Blockers/notes:
- Full documentation and sample migration wording remains for issue 005.
- Existing tests that intentionally use final_output_from now emit the new deprecation warning.
* Document workflow output selection contract
Key decisions:
- Use Workflow Output and Intermediate Output as the developer-facing terms for selected caller-facing emissions.
- Document output_from and intermediate_output_from as the canonical API, with output_from as an allow-list and unselected payloads hidden unless explicitly selected as intermediate.
- Add scenario and invalid-selection tables for workflow and orchestration docs, including legacy omission warnings, output_from='all', intermediate_output_from='all_other', list selections, invalid literals, overlap, duplicates, unknown selections, and empty explicit selections.
- Migrate samples away from final_output_from and output_executors except where compatibility aliases are explicitly documented.
