Python: add agent-framework-hosting-mcp channel (#6305)
* feat(python): add agent-framework-hosting-mcp channel Add a hosting channel that exposes the host target (agent or workflow) as a single Model Context Protocol tool over Streamable HTTP. The tool invocation routes through the host pipeline (ChannelContext.run/ run_stream) so sessions, linking, and run/response hooks apply. Maps the MCP request context to a ChannelSession isolation key and ChannelIdentity, and forwards streaming output as MCP progress notifications. Includes tests, README, and workspace registration.

Python: add agent-framework-hosting-a2a channel (#6306)
* feat(python): add agent-framework-hosting-a2a channel Add a hosting channel that exposes the host target (agent or workflow) as a peer agent over the Agent-to-Agent (A2A) protocol (JSON-RPC plus a served agent card). Requests are handled by a host-routed HostAgentExecutor that drives the host pipeline (ChannelContext.run/ run_stream) instead of wrapping the target directly, so sessions, linking, and run/response hooks apply. Maps the A2A conversation/context id to a ChannelSession isolation key and the caller to a ChannelIdentity; streaming emits incremental task artifacts. Includes tests, README, and workspace registration.

Simplify Python hosting core (#6492)
Remove linking, multicast, durable delivery, and host push machinery from the v1 hosting core. Keep those scenarios in a proposed follow-up ADR and update channel packages, samples, docs, tests, and workspace metadata around the smaller host/channel contract.

Python: feat(python): cross-channel hosting improvements (endpoint paths, Activity push, Telegram/Teams fixes) (#6307)
* Update hosting channel endpoint paths Treat channel paths as concrete endpoint paths so built-in channels can be mounted at their defaults or at the app root without sample-specific subclasses. Update docs, tests, and the Foundry Telegram Invocations sample accordingly. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Add push support to ActivityProtocolChannel Implement the ChannelPush protocol so the Activity Protocol channel can receive cross-channel fan-out (ResponseTarget.all_linked) and echo_input replay as a non-originating destination: - Add push() that reconstructs a proactive Bot Framework activity (bot/user swap) from the stored conversation reference and POSTs it to /v3/conversations/{id}/activities. - Record a ChannelIdentity (service_url, conversation, bot, user, channel_id, locale) on ChannelRequest.identity so the host registers the channel under its isolation key for fan-out resolution. - Route the streaming path through deliver_response so Activity-originated turns broadcast like Telegram/Discord. - Add tests for push delivery, service_url validation, ChannelPush instance check, and inbound identity recording. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Don't delete Telegram webhook on shutdown by default The TelegramChannel deleted its webhook on shutdown in webhook mode. During a rolling redeploy the new revision registers the webhook on startup, then the old revision's shutdown deletes it, silently breaking inbound delivery until the next boot. setWebhook is overwriting/idempotent, so startup re-asserts the webhook every boot and no teardown is needed. Add a delete_webhook_on_shutdown flag (default False) so teardown is opt-in for ephemeral deployments, and leave the webhook in place otherwise. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Fix Activity channel streaming on non-Teams channels (405 on updateActivity) The Activity Protocol channel streamed replies the Teams way: POST a placeholder, then PUT-edit it as tokens arrive. Only Teams supports the updateActivity REST op; Web Chat, Direct Line and the Emulator return 405 Method Not Allowed on the PUT, so the user saw only the placeholder. Gate the placeholder+edit flow on edit-capable channels (msteams). Other channels now buffer the stream and POST a single final message, mirroring the non-streaming path's fan-out and response-hook semantics. Also add a defensive 405 fallback inside the Teams edit loop so an unexpected 405 can never strand the user on the placeholder. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * fix(hosting-activity-protocol): don't parse Teams inline attachment content as a URI Teams message activities include a text/html attachment whose inline `content` is raw HTML (not a URL). _parse_activity fell back to `attachment["content"]` and passed it to Content.from_uri, raising ContentError ("URI must contain a scheme") and failing the whole turn, so Teams users got no response. Only treat `contentUrl` as a URI, require an absolute scheme, and skip unparseable attachments defensively instead of failing the message. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * feat(hosting-activity-protocol): native slash-command dispatch for Teams/Activity Add a commands= parameter to ActivityProtocolChannel that intercepts a leading /command (after stripping the bot's own @mention) and dispatches to ChannelCommand handlers, mirroring the Telegram channel. Unknown commands fall through to the agent. The channel run_hook is applied to command requests so handlers observe the same resolved isolation key as ordinary messages, and handler errors are swallowed (200, no Bot Service retry of non-idempotent commands). Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * feat(hosting): silent attributed Telegram echoes + Teams markdown rendering - hosting-telegram: send cross-channel input echoes with disable_notification (silent) and detect echo payloads so they aren't re-broadcast. - hosting-activity-protocol: render outbound + push activities as textFormat 'markdown' so Teams shows formatted replies (enables per-channel variants). Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * fix(hosting-activity-protocol): address PR #6307 review feedback Consult the host delivery pipeline even for empty streamed replies so ResponseTarget.none is honoured and non-originating fan-out is consulted instead of always emitting an originating "(no response)" message. Applies to both the progressive-edit (Teams) and buffered (Web Chat/Direct Line) streaming paths. Re-validate service_url against the allow-list in push(): the identity is read from a persisted store and push runs out-of-band, so the captured service_url must be re-checked before a bearer token is sent. Adds tests for empty-stream host consultation/suppression on both streaming paths and for push rejecting a disallowed service_url.

Python: add agent-framework-hosting-discord channel (#6081)
* Add Discord hosting channel Add an alpha agent-framework-hosting-discord package backed by Discord HTTP Interactions. The channel verifies signed slash-command requests, registers commands, runs hosted agents and ChannelCommand handlers, supports originating response hooks, streams by editing the original interaction response, and can push through Discord channel ids. Factor standard channel response-hook context application into hosting core so both host fan-out and originating channel replies use one helper. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Address Discord review chunking feedback Ensure Discord command replies are chunked and streaming preview edits stay under Discord's content limit while final streamed replies continue through the chunked reply path.

Python: add hosting Channels sample apps (#5645)
* samples(hosting): add hosting Channels sample apps under samples/04-hosting/af-hosting Adds five end-to-end sample apps under ``python/samples/04-hosting/af-hosting/`` that exercise the ``agent-framework-hosting`` Channels stack from the simplest single-channel case up to a multi-channel deployment with cross-channel identity linking. Samples (ordered by complexity) ------------------------------- * ``foundry_hosted_agent/`` — minimal Responses + Invocations host with a Foundry-backed agent and ``FoundryHostedAgentHistoryProvider``. ``agd``-deployable; bundles a ``Dockerfile`` and ``scripts/vendor-packages.sh`` that copies workspace packages into ``_vendor/`` for self-contained builds. ``_vendor/`` is gitignored. * ``local_responses/`` — single-channel Responses host with a ``run_hook`` that strips caller-supplied options and forces a reasoning preset. Demonstrates the hook seam over the uniform ``ChannelRequest`` envelope. * ``local_responses_workflow/`` — Responses + Invocations exposing a three-agent workflow with per-conversation checkpoint storage. * ``local_telegram/`` — Responses + Telegram with a ``@tool``, ``FileHistoryProvider``, hooks, and a ``ResponseTarget`` multicast variant (``call_server_multicast.py``) that pushes a single Responses reply to a separate Telegram chat. * ``local_identity_link/`` — full surface: Responses + Invocations + Telegram + Activity Protocol (Teams) + the ``EntraIdentityLinkChannel`` sidecar. Resolves per-channel ids onto a single Entra object id so a user's history follows them across surfaces. Notes ----- * Samples that use Telegram/Teams via Activity Protocol depend on the renamed ``agent-framework-hosting-activity-protocol`` package (see the PR-5 series). * All samples use ``[tool.uv.sources]`` editable workspace deps, except ``foundry_hosted_agent/`` which uses the ``./_vendor/`` self-contained layout for ``azd`` Docker builds. * Each sample includes a ``README.md`` with run instructions and an ``app.py`` ASGI entrypoint plus a ``call_server.py`` client harness. Depends on the prior hosting PRs (foundry-hosted-agent refactor + hosting-core + the per-channel packages). After those merge, this branch can be rebased onto ``main`` cleanly. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * samples(hosting): point sample deps at the feature/python-hosting GitHub branch Switches every sample's ``[tool.uv.sources]`` from in-monorepo editable path deps (which only resolve when running inside the agent-framework workspace) to git refs targeting the ``feature/python-hosting`` branch on ``microsoft/agent-framework``. Samples now install standalone outside the monorepo while the ``agent-framework-hosting*`` packages are still pre-PyPI; once they publish, the ``[tool.uv.sources]`` block can be dropped and the declared deps resolve from PyPI. Cleanup ------- * Drops ``foundry_hosted_agent/scripts/vendor-packages.sh``, ``_vendor/`` from ``.gitignore``, the ``hooks.prepackage`` block in ``azure.yaml`` and the ``COPY _vendor/`` step in the Dockerfile — vendoring is no longer needed because git refs make the deps network-resolvable from any context. * Drops obsolete ``workspace.pyproject.toml`` reference and ``scripts/`` / ``workspace.pyproject.toml`` entries from ``Dockerfile.dockerignore``. * Updates the foundry sample's Dockerfile to ``uv sync --no-dev`` (no ``--frozen``) so it locks fresh against the GitHub-hosted deps at build time. * Drops every committed ``uv.lock`` because the resolver needs network access to ``feature/python-hosting`` to lock — they regenerate the first time a user runs ``uv sync`` after the branch lands. * Refreshes the per-sample READMEs to mention the GitHub install path instead of "in-tree workspace packages". Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * samples(hosting): address PR #5645 review comments - foundry_hosted_agent/call_server.py: replace hard-coded project_endpoint and service_session_id with FOUNDRY_PROJECT_ENDPOINT, FOUNDRY_HOSTED_AGENT_NAME, and optional FOUNDRY_HOSTED_SESSION_ID environment variables. Session-id is now optional so the sample exercises the new-conversation path by default. - local_identity_link/app.py: * make_telegram_hook: apply the reasoning bump regardless of identity-link state (the previous early-return on linked chats silently dropped the high-effort preset for the very flow the sample exists to demonstrate). * make_responses_hook: add a prominent DEV-ONLY warning that the client-supplied entra_oid shortcut bypasses identity verification and must be replaced by a JWT validator in production. * /link command: early-return when chat_id is missing instead of minting an authorize URL keyed on "telegram:None" (which would poison the link store with a binding any future chat_id-less update would collapse onto). * Switch ENTRA_CERT_PATH / ENTRA_CERT_PASSWORD env vars to the longer ENTRA_CERTIFICATE_PATH / ENTRA_CERTIFICATE_PASSWORD names that the README already documents. * channels: Sequence[Channel] -> list[Channel] (the next line appends, which a Sequence type doesn't expose).

Python: add agent-framework-hosting-entra identity-link helpers (#5644)
* feat(hosting-entra): add Entra (Azure AD) identity-linking channel New ``agent-framework-hosting-entra`` package implementing a Microsoft Entra OAuth-based identity-linking channel for the Hosting framework. Mounts a small set of routes (``/entra/login``, ``/entra/callback``, ``/entra/whoami``) that walk a user through an Entra/Azure AD authorization-code flow and stick the resulting verified identity (``oid`` / ``email`` / ``tid``) onto the host's identity table so later requests on any other channel (Responses, Telegram, …) can be linked to the same user. Surface (re-exported from ``agent_framework_hosting_entra``): - ``EntraChannel`` -- concrete ``Channel`` implementation. Owns the three Starlette routes, signs/verifies short-lived ``state`` tokens to bind the round-trip to the originating channel, exchanges the authorization code for an ID token via MSAL, and writes the verified identity into the host's identity store via the standard ``ChannelIdentity`` plumbing so cross-channel push (e.g. send a Telegram message to the user who completed the link from Responses) works without the channels having to coordinate directly. - 14 unit tests covering route wiring, ``state`` issue / verify, callback exchange happy + failure paths, and identity-store write. Registers the package in ``python/pyproject.toml`` ``[tool.uv.sources]`` and adds the matching pyright ``executionEnvironments`` entry. Stacks on PR-2 (Hosting core); independent of PR-3 / PR-4 / PR-6. The cross-channel sample (``local_identity_link/``) that demonstrates this end-to-end alongside Responses + Telegram lands in PR-8 (samples). Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * fix(hosting-entra): close IDOR + reflected-XSS + open-redirect on the OAuth flow Three SECURITY-CRITICAL fixes flagged in round-2 review. 1. IDOR on /auth/start (3198518308). Without authentication the endpoint accepted (channel, channel_id) from the query string and bound *whoever signed in* to that pair. An attacker could bind their own Entra oid to a victim's per-channel id (e.g. `telegram:<victim_chat_id>`), redirecting all of the victim's future inbound traffic to the attacker's isolation key. Fix: introduce link_token_secret + mint_start_url(channel, id, ...). When set, /auth/start requires `exp` + `sig` (HMAC-SHA256 over `channel|channel_id|expires_at`) before issuing the redirect. Channels that hand out start URLs (a Telegram /link command after verifying the inbound webhook signature) call mint_start_url so the token proves the (channel, id) pair was authorised by the channel that owns the surface. Unsigned mode is opt-in and logs a loud WARNING at startup *and* on every accepted request. 2. Reflected XSS on /auth/callback (3198520256, 3198527896). `error`, `error_description`, channel_key (from the unauthenticated /start query), and `upn` (from a Graph response) flowed straight into the text/html response body unescaped. With the IDOR above, an attacker could stash `<script>` payloads in `channel` or `id` and serve them from the auth host's origin (full XSS on the auth surface — cookies/storage of anything else mounted there). Fix: html.escape() every value before HTML output. 3. Open redirect on `return_to` (3198524746). Accepted any URL. Fix: `_validate_return_to` allows only relative paths starting with `/` (and not `//`) or absolute URLs whose host equals the configured `public_base_url` host. Validated at /start mint time AND defensively re-validated at /callback before redirect. 12 new tests cover signed-token rejection (missing/forged/expired), mint helper requirements, startup warning visibility, XSS escaping on both error and success paths, and the open-redirect allowlist (external rejected, relative accepted, same-origin accepted, protocol-relative `//evil.example/` rejected).

Python: add agent-framework-hosting-activity-protocol channel (#5641)
* feat(hosting-activity-protocol): rename Bot Framework channel to ActivityProtocolChannel The existing Bot-Framework-via-Azure-Bot-Service channel was previously shipped under the name ``hosting-teams`` / ``TeamsChannel``. That name is misleading for what the channel actually does -- it speaks the Bot Framework Activity Protocol against Azure Bot Service, which fans out across MS Teams, Slack, Webex, Telegram-via-Bot-Service, etc., and does not provide any Teams-specific affordances. This PR renames the package atomically and frees the ``hosting-teams`` name for a future Teams-native channel built on ``microsoft-teams-apps`` (PR-5b, spec req #28). Renames (all in one commit): - Package: ``agent-framework-hosting-teams`` -> ``agent-framework-hosting-activity-protocol`` - Module: ``agent_framework_hosting_teams`` -> ``agent_framework_hosting_activity_protocol`` - Channel class: ``TeamsChannel`` -> ``ActivityProtocolChannel`` - Helper: ``teams_isolation_key`` -> ``activity_protocol_isolation_key`` (isolation key prefix ``teams:`` -> ``activity:``) - Channel name: ``"teams"`` -> ``"activity"``; default mount path ``/teams`` -> ``/activity`` - Internal helper: ``_parse_teams_activity`` -> ``_parse_activity`` - Worker task name + a couple of error strings updated for consistency Updates README.md and the module docstring to call out: - this is the channel-neutral Activity Protocol channel, - it surfaces what every Bot-Service-connected channel has in common (text in / text out), - a forthcoming ``agent-framework-hosting-teams`` package will layer Teams-specific affordances (adaptive cards, message extensions, dialogs, SSO, ...) on the same Bot Service transport. Workspace: registers ``agent-framework-hosting-activity-protocol`` in ``python/pyproject.toml`` and adds the matching pyright ``executionEnvironments`` entry. Behavior is unchanged. Pyright + mypy clean, 11 tests pass. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * review: address PR-5 round 2 feedback - security (#3198327004): add `service_url_allowed_hosts` constructor option (default `botframework.com` + `smba.trafficmanager.net`) and reject inbound activities whose `serviceUrl` host falls outside it with HTTP 400 — without this gate a malicious caller could redirect outbound replies (and the attached bearer token) to an attacker-controlled host - security (#3198324219): add `inbound_auth_validator` async callback; log a loud WARNING at startup when no validator AND no operator reverse-proxy is configured so the dev-mode bypass cannot accidentally ship to production. Document the contract: prototype intentionally does not ship JWT validation (out of scope); operators must plug a validator or terminate auth in front of the channel - retry semantics (#3198328746): distinguish transient outbound failures (httpx network errors, non-2xx from Bot Service) — return 502 so Bot Service retries — from deterministic agent failures — return 200 so Bot Service does not retry the same broken activity in a loop - bug (#3198330424): fix the placeholder-failure deadlock. When `send_initial_placeholder` fails, `activity_id` stays `None`, the edit-worker loop exit condition (`accumulated == last_sent`) is unreachable while no PUT is possible, and the worker would deadlock on `wake.wait()` forever after `worker_done` is set. Now: skip the worker entirely on placeholder failure and POST a single final activity at the end with whatever accumulated - tests (#3198334465, #3187178091, #3198336045): add coverage for - `_is_service_url_allowed` allow/deny matrix + webhook 400 on disallowed serviceUrl - `inbound_auth_validator` allow/deny/raises paths - outbound `Authorization: Bearer <token>` header presence in production mode and absence in dev mode - the streaming path (`_stream_to_conversation`): placeholder + final edit, placeholder-failure fallback (with timeout guard against deadlock regression), and empty-stream `(no response)` placeholder replacement - retry-signal differentiation: outbound `httpx.ConnectError` → 502; deterministic `ValueError` from the agent → 200 Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * test(hosting): drop redundant @pytest.mark.asyncio decorators asyncio_mode = "auto" is configured in pyproject.toml across the hosting packages, so individual @pytest.mark.asyncio decorators are unnecessary.

Python: add agent-framework-hosting-telegram channel (#5643)
* feat(hosting-telegram): add Telegram channel package New ``agent-framework-hosting-telegram`` package implementing the Telegram Bot API channel for the Hosting framework. Mounts a webhook endpoint (``POST /telegram/webhook``) and an in-process polling loop onto an ``AgentFrameworkHost`` and translates Telegram ``Update`` payloads to/from the channel-neutral ``ChannelRequest`` / ``HostedRunResult`` plumbing. Surface (re-exported from ``agent_framework_hosting_telegram``): - ``TelegramChannel`` -- concrete ``Channel`` implementation. Owns the webhook route + an optional ``getUpdates`` long-polling lifespan, parses Telegram ``Update``s into ``ChannelRequest`` (text, photo, document, voice, callback_query, …), runs the optional ``ChannelRunHook``, calls back into the ``ChannelContext`` to invoke the agent target, and posts the response back via ``sendMessage`` / ``sendChatAction`` / ``answerCallbackQuery`` on the Telegram Bot API. Honours ``DeliveryReport.include_originating`` so cross-channel pushes can target the originating Telegram chat without double-acking. - Native fields the channel doesn't lift onto ``ChannelRequest`` (e.g. ``chat.type``, ``message.message_id``, ``callback_query.data``) are attached to ``ChannelRequest.attributes`` so a ``ChannelRunHook`` can pick them up via the standard ``protocol_request=`` kwarg. - 13 unit tests covering route wiring, ``Update`` parsing across the common content shapes, hook composition, and originating vs non-originating delivery branches. Registers the package in ``python/pyproject.toml`` ``[tool.uv.sources]`` and adds the matching pyright ``executionEnvironments`` entry. Stacks on PR-2 (Hosting core); independent of PR-3 / PR-4. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * fix(hosting-telegram): preserve in-chat ordering, ack-before-run, drain shutdown - Replace per-update task fan-out with per-chat asyncio.Queue + worker. Telegram only guarantees update ordering up to getUpdates; the previous code spawned one task per update, which broke ordering for adjacent updates in the same chat. Updates are now serialised per chat_id (so /start then "what's the weather" can't race) while different chats still process in parallel. - Webhook handler now acks (200) immediately and runs the agent in the per-chat worker. Telegram redelivers any update the webhook doesn't 200 within ~60 seconds, so a streamed agent reply that runs longer than that previously triggered a retry storm and duplicate replies. - _on_shutdown now drains everything: poll task → per-chat workers → webhook-spawned dispatcher tasks (the new ack-before-run path), then deletes the webhook + closes the HTTP client. Previously webhook tasks were not tracked at all, so an in-flight agent invocation could leak past app shutdown. - _enqueue_update extracts chat_id from message / edited_message / callback_query; updates with no resolvable chat fall back to a one-shot dispatcher task that's still tracked in _update_tasks for shutdown. - Webhook handler now also returns 400 on malformed JSON / non-object payloads instead of crashing the request. 4 new tests cover per-chat serial ordering, parallel-across-chats isolation, ack-before-run latency, and shutdown drain.

Mounts onto an ``AgentFrameworkHost`` like any other channel. Surface (re-exported from ``agent_framework_hosting_invocations``): - ``InvocationsChannel`` -- concrete ``Channel`` implementation.

* feat(hosting-responses): add OpenAI Responses-shaped channel package New ``agent-framework-hosting-responses`` package implementing the OpenAI Responses-shaped HTTP channel for the Hosting framework. Mounts ``POST /responses`` (and a ``/responses/{response_id}`` GET) onto an ``AgentFrameworkHost`` and translates the OpenAI Responses wire shape to/from the channel-neutral ``ChannelRequest`` / ``HostedRunResult`` plumbing. Surface (re-exported from ``agent_framework_hosting_responses``): - ``ResponsesChannel`` -- concrete ``Channel`` implementation. Owns the Starlette route(s), parses inbound JSON into ``ChannelRequest``, runs the optional ``ChannelRunHook``, calls back into the ``ChannelContext`` to invoke the agent target, builds Responses envelopes (sync JSON or SSE), and respects ``DeliveryReport.include_originating`` so cross-channel push routes only ack to the originating Responses caller. - The minted ``response_id`` is propagated via the host's ContextVar machinery so storage-side history providers (e.g. ``FoundryHostedAgentHistoryProvider``) persist envelopes against the same id the channel returns. - 48 unit tests covering route wiring, parsing of each Responses input shape, hook composition, sync vs streaming paths, and originating vs non-originating delivery branches. Registers the package in ``python/pyproject.toml`` ``[tool.uv.sources]`` and adds the matching pyright ``executionEnvironments`` entry.

Python: refactor FoundryHostedAgentHistoryProvider onto Foundry SDK (#5637)
* refactor(foundry_hosting): build FoundryHostedAgentHistoryProvider on azure.ai.agentserver SDK Rebuilds the Foundry hosted-agent history provider on top of ``azure.ai.agentserver``'s ``FoundryStorageProvider`` instead of the in-house ``_HttpStorageBackend``. Splits the monolithic ``_responses.py`` into focused modules: - ``_history_provider.py`` — new ``FoundryHostedAgentHistoryProvider`` that talks to the SDK's ``FoundryStorageProvider``, threads ``response_id`` / ``previous_response_id`` through ``ContextVar``s via ``bind_request_context``, and lifts host-bound isolation keys (``x-agent-{user,chat}-isolation-key``) from the optional ``agent_framework_hosting`` package into a provider-local ``IsolationContext`` so the storage layer carries the correct partition keys without channels having to know about them. - ``_shared.py`` — extracts all SDK ``Item`` / ``OutputItem`` ↔ framework ``Message`` conversion helpers into one place so both ``_responses.py`` and the new history provider can share them. Restores ``_convert_file_data`` for inline ``input_file`` payloads, and the hosted-MCP routing for ``custom_tool_call_output`` items whose ``call_id`` carries the ``mcp_*`` prefix. - ``_ids.py`` — shared id helpers. - ``_responses.py`` — shrinks ~700 lines, re-exports converters for back-compat with existing tests. - ``tests/test_history_provider.py`` — exercises the new provider against a fake SDK backend; the host-isolation test is gated on the optional ``agent_framework_hosting`` import. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * feat(foundry_hosting): add local_storage_root for file-based dev history Adds an optional `local_storage_root: str | Path | None` parameter to `FoundryHostedAgentHistoryProvider`. When set and the provider is running outside a Foundry Hosted Agent container, conversations are persisted to JSONL files via `agent_framework.FileHistoryProvider` laid out as: {root}/{user_key or '~none'}/{chat_key or '~none'}/{session_id}.jsonl Hosted mode (FOUNDRY_HOSTING_ENVIRONMENT set) ignores the option with a one-time INFO log so Foundry storage always wins on the platform. The in-memory fallback is unchanged when the option is omitted. Path safety: isolation segments are validated against the same character allowlist FileHistoryProvider uses for session-id stems and base64-url-encoded with a reserved "~iso-" prefix when unsafe. "~none" sentinel for missing keys can never collide with a real isolation key (real keys starting with "~" are encoded). The resolved target dir is also re-checked to be inside the configured root. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * fix(foundry_hosting): address PR-1 review comments - _shared.py:_capture_raw narrows `except Exception` to `except TypeError` and emits a WARNING with traceback so the lossy fallback to a synthesized round-trip is observable. Mirrors the reviewer suggestion. - _history_provider.py:save_messages narrows `except Exception` to `except FoundryStorageError` so only storage-validation failures (4xx/5xx, opaque server errors) are swallowed. Network / TLS / auth / payload-builder bugs propagate so the caller can retry / alert. Adds an instance-level `failed_writes` counter operators can poll for silent-drop visibility. - _history_provider.py id-stamping loop: drops the `contextlib.suppress(AttributeError, TypeError)` around `item.id = new_id` so SDK contract changes surface in the test suite instead of silently corrupting the chain (the storage backend rejects the entire `create_response` with HTTP 500 when synthetic prefix-based ids leak through). `import contextlib` removed. - tests: * Unit-cover `foundry_response_id` / `foundry_response_id_factory` / `foundry_item_id` so SDK `IdGenerator` contract changes are caught locally. * Cover the `save_messages` wire payload: required-by-storage fields (`background`, `parallel_tool_calls`, `instructions`, `agent_reference`), env-var-driven stamping (`FOUNDRY_AGENT_NAME` / `FOUNDRY_AGENT_VERSION` / `FOUNDRY_AGENT_SESSION_ID` / `MODEL_DEPLOYMENT_NAME` with `AZURE_AI_MODEL_DEPLOYMENT_NAME` fallback), and the rule that `model` / `agent_session_id` / `agent_reference.version` are omitted (not stamped to `None`) when their env vars are unset. * Cover the `FOUNDRY_AGENT_SESSION_ID` last-resort chain anchor on both the get and save paths, including the prefix gate that blocks non-`caresp_*`/`resp_*` values from reaching storage, and the precedence rule that a host binding wins over the env. * Replace the old `test_save_messages_swallows_backend_errors` with two tests asserting the new contract: storage errors are swallowed and bump `failed_writes`; everything else propagates and leaves the counter at zero. 141 unit tests pass; mypy + pyright + ruff clean. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * fix(foundry_hosting): address PR-1 round-2 review comments - Hosted detection now delegates to AgentConfig.from_env().is_hosted so a future Foundry SDK rename of FOUNDRY_HOSTING_ENVIRONMENT propagates automatically; drop the local _ENV_FOUNDRY_HOSTING_ENVIRONMENT constant. - Drop the FOUNDRY_AGENT_SESSION_ID fallback in both get_messages and save_messages: per the SDK it identifies the *container instance*, not the conversation, so chaining off it would silently merge unrelated conversations across container restarts. The host-bound previous_response_id (set by ResponsesChannel) is the only authoritative anchor; the env value is still stamped into the persisted envelope's agent_session_id for operator correlation. - Update module docstring + replace TestFoundryAgentSessionIdAnchor with assertions for the new contract (env var ignored as anchor, still stamped onto persisted envelope, host binding wins). Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * refactor(foundry_hosting): reconcile with upstream main (#5851, #5666) Brings the FoundryHostedAgentHistoryProvider refactor branch back into sync with the foundry_hosting changes that have landed on upstream main since PR-1 was opened: * #5851 (path traversal in checkpoint storage, CWE-22). The workflow-host code in ``_responses.py`` builds a ``FileCheckpointStorage`` from a caller-controlled ``context_id`` (``previous_response_id`` / ``conversation_id`` / ``response_id``). Switch both call sites to route through ``_checkpoint_storage_for_context``, which rejects separators, NUL bytes, drive letters, absolute paths, and all-dot segments, and enforces ``is_relative_to(root)`` before any directory is created. * #5666 (function approval flow). Make the SDK-Item → AF-Message conversion helpers in ``_shared.py`` async and accept an optional ``approval_storage`` keyword: - ``_items_to_messages`` / ``_item_to_message`` / ``_item_to_message_inner`` - ``_output_items_to_messages`` / ``_output_item_to_message`` / ``_output_item_to_message_inner`` For ``mcp_approval_request`` / ``mcp_approval_response`` items the helpers now load the original function-call Content from the approval storage (via ``ApprovalStorage.load_approval_request``) instead of synthesising a placeholder. This matches upstream semantics and lets approval round-trips reconstruct the real payload. The ``ApprovalStorage`` Protocol moves to ``_shared.py`` so the conversion helpers can reference it without pulling in ``_responses.py`` (which would create a circular import). The concrete ``InMemoryFunctionApprovalStorage`` and ``FileBasedFunctionApprovalStorage`` stay in ``_responses.py`` next to the host that owns them, and re-export ``ApprovalStorage`` from ``_shared`` for compatibility. The workflow-host streaming path passes its own ``self._approval_storage`` into ``_to_outputs`` so approval requests are saved at emit time. * Bump ``_history_provider.FoundryHostedAgentHistoryProvider.get_messages`` to ``await`` the now-async ``_output_items_to_messages`` call. No public API change beyond the new keyword-only ``approval_storage`` parameter on the four conversion entry points.

Python: add agent-framework-hosting core package (#5638)
* feat(hosting): add agent-framework-hosting core package New ``agent-framework-hosting`` package implementing ADR 0026 / SPEC-002: the channel-neutral host that lets a single ``Agent`` (or ``Workflow``) fan out across multiple wire protocols ("channels") behind one Starlette ASGI app. Surface (re-exported from ``agent_framework_hosting``): - ``AgentFrameworkHost`` — wraps a hostable target, mounts channels onto an ASGI app, owns per-isolation-key ``AgentSession`` reuse, threads request context (``response_id`` / ``previous_response_id``) into context providers via an ``ExitStack`` of ``bind_request_context`` calls, and exposes an opt-in Hypercorn ``serve()`` helper (extra ``[serve]``). - ``Channel`` protocol + ``ChannelContribution`` — the surface a channel package implements (routes, lifespans, identity hooks, …). - ``ChannelRequest`` / ``ChannelSession`` / ``ChannelIdentity`` / ``ChannelPush`` / ``ChannelCommand[Context]`` / ``ChannelRunHook`` / ``ChannelStreamTransformHook`` / ``DeliveryReport`` / ``HostedRunResult`` / ``ResponseTarget`` / ``ResponseTargetKind`` / ``apply_run_hook`` — channel-side dataclasses + helpers. - ``IsolationKeys`` + ``ISOLATION_HEADER_USER`` / ``..._CHAT`` + ``get/set/reset_current_isolation_keys`` — the host's ASGI middleware reads the ``x-agent-{user,chat}-isolation-key`` headers off each inbound request and exposes them to the agent stack via a ``ContextVar`` so storage-side providers (e.g. ``FoundryHostedAgentHistoryProvider``) can apply per-tenant partitioning without channels having to forward anything. Includes 45 unit tests covering the host, channel contributions, isolation contextvar, and shared types. Registers the package in ``python/pyproject.toml`` ``[tool.uv.sources]`` and adds the matching pyright ``executionEnvironments`` entry for tests. Hypercorn is an optional dependency (``[serve]`` extra); the soft import in ``serve()`` is annotated for pyright since it isn't on the default install. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * fix(hosting): address PR-2 review comments Source-code changes - _suppress_already_consumed: narrow contract — RuntimeError now logs at WARNING with exc_info; non-RuntimeError still logs at exception(). Docstring clarifies that any non-clean teardown is observable. - _BoundResponseStream: add aclose() and route __await__ through get_final_response() so the binding is always released — fixes contextvar leak when channels abandon the stream or use the await-the-stream convenience. - Lifespan: aggregate startup/shutdown callback errors; every callback runs, all failures are logged with their qualname, and the first error is re-raised so Starlette still aborts boot. - _build_run_kwargs: switch session-cache write to dict.setdefault so concurrent racers cannot orphan a session if create_session ever yields. - _deliver_response: introduce DeliveryReport.failed for push outages vs explicit "no link" drops; an outage no longer triggers an originating fallback so the channel can decide degraded behaviour. Test additions - tests/test_isolation.py (new): full coverage of IsolationKeys, the contextvar helpers, header constants, and end-to-end ASGI middleware lift / reset / passthrough. - tests/test_host.py: TestBindRequestContext, TestBoundResponseStream (aclose / __await__ / __getattr__ forwarding / double-close idempotency), TestWrapInputListMessages (list[Message] LAST precedence), TestLifespanAggregation (startup + shutdown). - tests/test_types.py: TestApplyRunHook (sync/async/None), and TestDeliveryReport (new failed field). - Updated test_push_exception_marks_skipped -> test_push_exception_lands_in_failed_no_fallback to match the new delivery contract. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * fix(hosting): address PR-2 round-2 review comments - Refactor workflow checkpoint restoration into shared helpers (_restore_workflow_checkpoint for blocking; the streaming sibling drains the rehydration stream) so the blocking and streaming paths rehydrate identically — clarifies the previously inline _maybe_restore by hoisting the pattern next to the blocking call site. - Document that blocking workflow output is text-only by design; richer modalities ride the streaming AgentResponseUpdate channel, which preserves all content parts. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * review: address PR-4 _host.py round 2 feedback These review comments were filed on PR-4 (#5640) but target lines that live in the hosting-core package (PR-2 / #5638), so the fixes land here and PR-4's stack will pick them up on rebase. - _suppress_already_consumed: narrow the RuntimeError catch to the two documented benign messages (`Inner stream not available`, `Event loop is closed`); any other RuntimeError now logs at ERROR with a full traceback so executor bugs / runner-context state errors / checkpoint RuntimeErrors during the post-run flush no longer masquerade as benign cleanup noise. Still no propagation (we're in an async-generator finally during teardown) — see the docstring. - _restore_workflow_checkpoint{,_streaming}: log a WARNING when a non-None latest checkpoint drains to zero events, so a stale or partially-written checkpoint_id surfaces as an operator signal instead of a silent state-loss. (The `deliver_response` "no destinations resolvable" vs "every destination errored" concern raised in 3198268038 is already addressed by the existing `failed` vs `skipped` distinction surfaced through `DeliveryReport.failed` — see lines 1080-1102 and the `DeliveryReport` docstring.) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * fix(hosting): reject path-traversal patterns in checkpoint isolation_key The host's `_resolve_checkpoint_storage` joined `request.session.isolation_key` directly into the configured `checkpoint_location`. The key is caller- controlled — sourced from inbound headers (`x-agent-{user,chat}-isolation-key` injected by the Foundry runtime), from channel-supplied derivations such as `telegram:<chat_id>` / `entra:<oid>`, or from values set by a channel `run_hook`. A value like `../../../etc/foo` or an absolute path would let the resulting checkpoint directory escape the configured root (CWE-22). This matches the path-traversal class fixed upstream in #5851 for the foundry_hosting checkpoint storage. New `_checkpoint_path_for_isolation_key(root, isolation_key)` helper: - Uses a denylist (not allowlist) so legitimate namespaced keys (`telegram:42`, `entra:abc-def`) continue to pass through unmodified. - Rejects path separators (`/`, `\`), NUL, all-dot reductions (`.`, `..`, `...`, ...), absolute paths (`os.path.isabs`), and drive-letter prefixes (`os.path.splitdrive` plus an explicit `^[A-Za-z]:` check so payloads crafted on a POSIX host still fail closed if the resulting directory ever round-trips to Windows storage). - After joining, resolves both sides and verifies `target.is_relative_to(root)` as defence-in-depth. `_resolve_checkpoint_storage` now logs a WARNING and returns `None` for invalid keys rather than crashing the request — checkpointing is best- effort and we prefer dropping it to letting one malformed key abort an otherwise valid agent run. Tests: - `TestCheckpointPathForIsolationKey` exercises the helper directly with legitimate keys (alphanumeric, `:`-namespaced, dotted, 200-char), all rejected traversal patterns from #5851's MSRC repro list, and non-string input. - `TestHostWorkflowCheckpointingPathTraversal` verifies the end-to-end request path: a traversal key (`../escape`) and an in-key separator (`evil/sub`) both produce a successful agent response with no files written under `checkpoint_location`, and the traversal case logs a WARNING citing `isolation_key`. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * fix(hosting): address PR-2 round-3 review feedback + add response hooks Round-3 review comment fixes: - _types.py: drop the _EMPTY_MAPPING sentinel; ChannelIdentity.attributes uses plain dict() as the default — simpler, no extra symbol to track. - _host.py: drop the local `import asyncio` + `from typing import cast as _cast` inside `serve()`; rely on the module-level imports. - _host.py: switch `_log_incoming` to structured `extra={...}` payloads for both INFO and DEBUG so log aggregators get queryable fields. - _host.py: delete `_flat_context_providers` and stop descending into a `.providers` attribute. Aggregator providers (AggregateContextProvider / ContextProviderBase) are responsible for forwarding `response_context` to their children themselves; the host treats whatever `agent.context_providers` exposes as the final, flat list. - _host.py: stop collapsing agent / workflow output to text. `_invoke` forwards `AgentResponse.messages` (and `raw_response`) on the `HostedRunResult`. `_invoke_workflow` builds a per-event message list via a new `_workflow_output_to_messages` helper that preserves AgentResponse / AgentResponseUpdate / Message / Content branches and falls back to text only for arbitrary objects. - _host.py: `_workflow_event_to_update` carries Content payloads through unchanged so multi-modal workflow outputs (images, function-call metadata, ...) survive into channels. New features (per design discussion in the PR thread): - HostedRunResult: rebuilt around `messages: list[Message]` with `.text` / `.contents` as projections, a `raw_response` slot for the underlying AgentResponse, and a `replace(messages=..., raw_response=...)` clone helper used by the delivery layer for per-destination isolation. The `HostedRunResult(text="...")` ctor is preserved as a back-compat shim that synthesises a single assistant text message. - ResponseTarget: gain `echo_input: bool = False` (also exposed on `.channel(name, *, echo_input=...)` / `.channels([...], *, echo_input=...)`). When set, the host pushes the originating user message to each non-originating destination before the agent reply. Channels can filter or transform echoes via their response_hook. - DeliveryReport: add `echoed` / `echo_failed` tuples to surface per-destination outcomes of the new echo phase. Echo failures do not abort the corresponding response push on the same destination. - ChannelResponseHook + ChannelResponseContext + apply_response_hook: duck-typed `response_hook` attribute on channels for per-destination post-processing. Receives a clone of the HostedRunResult and a context carrying the request, channel name, destination identity, originating flag, and `is_echo` phase flag. Channels stay modality-aware (text-only wires flatten via the hook; card-capable channels render structured contents directly). - _deliver_response: clone-before-hook fan-out so a hook mutating one channel's payload cannot leak into another destination's view. Tests: - Update _FakeAgentResponse to expose `.messages` (single assistant text message synthesised from `text`) so existing tests pass unchanged on the new multi-modal _invoke path. - Replace the obsolete `test_bind_descends_one_level_into_providers_attribute` with a regression guard asserting the host does NOT descend into `.providers` (matches new contract). - New tests for HostedRunResult multi-modal preservation, echo_input fan-out with success + failure, response_hook applied per destination, per-destination mutation isolation, and is_echo phase observability. Docs: - spec 002: rewrite Canonical flow with the new input → run_hook → host → target → wrap → per-destination clone → response_hook → push pipeline; document multi-modality contract and per-destination cloning; add `echo_input` row to ResponseTarget table; rewrite HostedRunResult/HostedStreamResult row; add ChannelResponseHook / ChannelResponseContext / apply_response_hook table; log decisions Q28 (no host-side text collapse), Q29 (duck-typed response_hook), Q30 (opt-in `echo_input` on ResponseTarget). - ADR 0026: add ChannelResponseHook + multi-modality bullets; surface `echo_input` on the ResponseTarget bullet. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * fix(hosting): drop HostedRunResult(text=...) back-compat shim; use from_text() Pre-release cleanup — no released callers to break, so consolidate on one canonical entry point plus a classmethod for the ergonomic single-text-message case: - HostedRunResult.__init__ takes ``messages`` positionally (required); no more ``text=`` kwarg overload, no more "synthesise an empty message when no args" path. - New HostedRunResult.from_text(text, *, role="assistant", raw_response=None) classmethod for the common "wrap a single text content as one message" case (tests, channels emitting plain strings, the echo-input phase wrapping a user's text turn). - ``_build_echo_payload`` uses ``HostedRunResult.from_text(raw, role="user")`` for the ``str`` and fallback branches; the other branches use the plain ctor with explicit ``Message`` lists. - Tests rewritten to use ``from_text("reply")`` everywhere ``HostedRunResult(text="reply")`` appeared. Added an explicit ``test_from_text_role_kwarg_overrides_default`` regression guard. - spec 002: HostedRunResult row updated to describe the ``from_text(text, *, role="assistant")`` classmethod instead of the removed back-compat shim. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * refactor(hosting-core): reshape HostedRunResult into generic typed envelope Replace the flattened multi-modal HostedRunResult (carrying messages/raw_response/.text projections) with a typed generic envelope around the target's full-fidelity output: class HostedRunResult(Generic[TResult]): result: TResult session: AgentSession | None - Agent targets produce HostedRunResult[AgentResponse]; channels read result.messages, result.text, result.value, result.response_id, result.usage_details directly off the underlying response. - Workflow targets produce HostedRunResult[WorkflowRunResult]; channels iterate result.get_outputs() and inspect result.get_final_state() themselves (the host no longer collapses workflow outputs onto a synthesised message list). - The echo-input phase synthesises a HostedRunResult[AgentResponse] wrapping the user's turn so the same per-destination delivery machinery applies. - replace() is now {result, session} only; the host's clone is shallow — channels that need to mutate result itself are responsible for their own deep copy. Rationale: the earlier shape pre-shaped target output (collapsing workflows onto a Message list, losing per-executor outputs, final state, and structured value affordances). Carrying the target output unchanged keeps the host modality-agnostic, gives channel authors static typing where they want it, and removes 30+ lines of host-side projection helpers. Also updates ADR 0026 + spec 002 (Q3, Q28, Q29 amended; new Q31 captures the generic-envelope decision and rationale). Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * docs(hosting-core): document echo vs response distinction for push channels The host already encodes the echo-vs-response phase via the underlying Message.role on the pushed HostedRunResult: - echo phase: payload.result.messages[*].role == "user" - response phase: payload.result.messages[*].role == "assistant" Both pushes go through the same ChannelPush.push(identity, payload) entry point. Channels distinguish either by inspecting role (which works for any push-capable channel) or — when a response_hook is wired — by branching on ChannelResponseContext.is_echo directly. Expand the ChannelPush Protocol docstring to make this discoverable for channel implementers (esp. chat bots that cannot impersonate the user on their wire and need to render echoes as quoted / prefixed blocks rather than as bot replies). Mirror the explanation into the spec's echo_input section.

Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * docs(hosting): add authorization profiles + IdentityAllowlist seam to ADR/spec Composes `require_link` + `allowlist` into three named profiles (open, forced-link, allowlist) with the allowlist itself keyed on either the channel-native id (pre-link) or a verified IdP claim (post-link), plus `AnyOf`/`AllOf` combinators for mixed setups. Lifts the design into an explicit host seam (`host.authorize(...)` → `AuthorizationOutcome` of `Allowed` / `LinkRequired` / `Denied`) instead of leaving each channel to roll its own. Key contract bits: - Tri-state `AllowlistDecision` (ALLOW / DENY / ABSTAIN) so claim-based lists can ABSTAIN until claims are available without composition silently flipping that into DENY. - `AuthorizationContext` carries explicit `phase` + `claim_source` so allowlists can tell pre-link from post-link without overloading `verified_claims is None`. - Channel-side `allowlist: ... | Literal["inherit"] | None` with an explicit inheritance sentinel, so the host-level `default_allowlist` is opt-out, not opt-in. - Construction-time validator rejects silent-deny configurations (`LinkedClaimAllowlist` without a claim source) with a typed `ChannelConfigurationError`. - Group-chat denial mirrors the existing `LinkChallenge` DM-redirect pattern; only the redacted `user_message` reaches the wire, structured `log_details` stay in telemetry. Ships in two waves: the Protocol + `NativeIdAllowlist` + config validator land with the next core PR ahead of the linker; the full pipeline + `LinkedClaimAllowlist` enforcement land with the `IdentityLinker` core PR. Updates: ADR 0026 (summary bullet + conceptual-API table row + resolved Q16), spec 002 (new req #22, renumbered v1 fast-follow #23..#29 and stretch #30..#31, new "Authorization profiles and the IdentityAllowlist seam" subsection, inbound-ownership row, resolved Q32, follow-up entry). Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * feat(hosting): add DurableTaskRunner seam + runtime_mode auto-detect Introduces the explicit long-running vs ephemeral runtime distinction and a generic DurableTaskRunner Protocol that owns non-originating push dispatch — collapsing the previous deliveries[] per-destination state machine, SupportsDeliveryTracking provider capability, and Foundry update_item service ask down to a single immutable intended_targets[] write on the message. Spec / ADR: - New §"Runtime modes" with auto-detect markers + defaults matrix. - Rewrites §"Delivery tracking" → §"Intended targets + durable delivery": intent-only on the message, operational state lives in the runner. - New §"Durable task runner" defining DurableTaskRunner / RetryPolicy / TaskHandle / TaskStatus. - Drops §SupportsDeliveryTracking and §Foundry update_item gap. - Resolved Qs: 12, 18, 21, 26 revised; new 17/18/19 (ADR) and 33/34/35 (spec). Code: - New _runner.py with InProcessTaskRunner (asyncio + bounded retry, bounded terminal-status cache, register-after-start guard, shutdown drain). - _host.py: runtime_mode + durable_task_runner ctor params; auto-detect via FOUNDRY_HOSTING_ENVIRONMENT / AZURE_FUNCTIONS_ENVIRONMENT / AWS_LAMBDA_FUNCTION_NAME; HOSTING_PUSH_TASK_NAME handler registered eagerly so _deliver_response can be called outside the lifespan; _handle_push_task does echo-then-response inline per destination; _deliver_response now schedules one task per destination via the runner (DeliveryReport.pushed = scheduled; .failed = schedule-time outage only). - _types.py: new DurableTaskRunner Protocol + RetryPolicy / TaskHandle / TaskStatus; DeliveryReport drops echoed / echo_failed (echo outcome owned by the runner). - __init__.py exports the new public surface. Tests: 132 passing, 90% coverage. New test_runner.py covers InProcessTaskRunner success/retry/terminal-failure/cancellation/ register-after-start, runtime-mode auto-detect with synthetic env, and the warning-on-ephemeral-without-runner path. test_host.py delivery tests use a sync runner fake for deterministic assertions and validate the new "schedule succeeded vs runner backend unreachable" semantics. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * feat(hosting): rubber-duck round-5 — strict ephemeral, codec seam, allowlist Wave-1, drop DeliveryReport Adopts the rubber-duck-approved package of changes from the round-5 review of PR #5638 (modulo DeliveryReport.failed — the value type is removed entirely now that durable delivery covers the failure surface, per user direction). Code: - Drop DeliveryReport value type; host-internal _deliver_response returns bool. Failure observability is now logs (in-process) / runner backend (durable adapters). - Strict ephemeral default: ephemeral runtime_mode with the default in-process runner raises RuntimeError; opt-in via allow_in_process_runner=True (warns). - ChannelPushCodec Protocol + DurableTaskPayloadMode enum + _validate_runner_codec_pairing so JSON-mode runners can be safely paired with channels via codecs; _handle_push_task accepts both object- and JSON-envelope shapes. - ResponseTarget.identity(...) / .identities([...]) builders + IDENTITIES kind for explicit caller-supplied recipients; field rename identities → _target_identities (private) with a target_identities property to resolve the classmethod collision. - Intent-only audit: _annotate_intended_targets writes hosting.intended_targets / skipped_targets / includes_originating / originating_channel onto assistant messages — single immutable write per the runner-owned operational-state model. - InProcessTaskRunner: 2-phase drain on shutdown (shutdown_grace_seconds, default 5.0) so a clean shutdown does not abandon work mid-retry; payload_mode = OBJECT class-level. - Echo idempotency: _handle_push_task tracks an echo_done cursor on runner-owned task state so a retry that fires after the echo phase succeeded does not double-echo. Wave-1 authorization seam (full landing): - New _authorization.py with AllowlistDecision tri-state, AuthorizationContext, IdentityAllowlist Protocol, AllowAll / NativeIdAllowlist (with async loader cache + channel-scope ABSTAIN) / LinkedClaimAllowlist (raise-until-Wave-2) / AnyOfAllowlists / AllOfAllowlists / CallableAllowlist built-ins, Allowed / LinkRequired / Denied outcomes, ChannelConfigurationError. - Host(default_allowlist=..., identity_linker=...) + per-channel allowlist parameter with 'inherit' / None semantics. - _validate_channel_authorization enforces all three rules at construction: claim-source requirement, linker presence for require_link=True (elevated from no-op — must not ship unenforced), and NativeIdAllowlist(channel=...) typo detection. Combinator-walking via _flatten_allowlists catches nested misconfigs. - host.authorize(...) for the native-id pipeline: open path returns Allowed with auto-issued <channel>:<native_id> isolation key (or the existing key when the identity has been seen); ABSTAIN on a claim-required allowlist maps to Denied(reason_code='allowlist_requires_link') until Wave 2 wires the linker to convert it to LinkRequired. Spec / ADR: - docs/specs/002-python-hosting-channels.md: Wave-1 status updated to reflect the linker-presence rule elevation and the host.authorize landing; new sub-sections (codec contract, drain, echo cursor); Qs 18 / 21 DeliveryReport references purged; new resolved Qs 36–40 covering the strict-ephemeral default, codec contract, DeliveryReport removal, echo cursor, and drain. - docs/decisions/0026-hosting-channels.md: Q12 DeliveryReport reference purged; Q16 updated to reflect Wave-1 landing; new resolved Qs 20 (codec contract) + 21 (strict ephemeral / drain / echo cursor). Tests: - New tests/test_authorization.py (35 cases) covering every Wave-1 built-in, the three validator rules, combinator decision semantics, and host.authorize across open / allow / deny / abstain-with-claim-dep / abstain-without-claim-dep paths plus existing-key reuse and verified-claims propagation. - tests/test_host.py: TestDeliverResponse rewritten for the bool return + runner.scheduled-count assertions; new tests for IDENTITIES variant + echo idempotency. - tests/test_runner.py: strict-ephemeral now expects RuntimeError; allow_in_process_runner opt-in tests; shutdown drain test; payload_mode default test. - tests/test_types.py: TestDeliveryReport removed; new TestDurableTaskPayloadMode + TestResponseTargetIdentities. Validation: 178 tests pass, 91% coverage, fmt + lint + pyright + mypy clean.

Doc-only; no API or behaviour change. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * feat(hosting): add opt-in disk persistence via state_dir Long-running hosts (always-on container, single-VM bot, local dev) lose state on every restart today. Add an opt-in disk persistence layer under a new `state_dir` constructor parameter on `AgentFrameworkHost` that survives process restarts without taking on a heavyweight database dependency. Backed by `diskcache` (installed via the new `[disk]` optional extra). An OS-level advisory file lock guarantees single-owner semantics so two hosts pointed at the same directory cannot double-execute scheduled pushes. What persists when `state_dir` is set: - Pending durable-task records — scheduled-but-not-yet-completed pushes replay on the next host startup via `InProcessTaskRunner.resume()`. Records that crashed mid-attempt resume with the already-consumed retry budget (no full-budget re-grant). - `_session_aliases` — per-isolation-key session-id rewrites. - `_active` — most-recently-active channel per isolation key. - `_identities` — `ChannelIdentity` rows for fan-out targeting, including nested mutations of the form `self._identities[ik][channel] = identity`. The `state_dir` parameter accepts any of: - `None` — today's purely in-memory behaviour. - `str` / `PathLike` — single root; host auto-creates `runner/` and `sessions/` subfolders. - `HostStatePaths` TypedDict / plain mapping — per-component overrides routed to different roots. Unknown keys raise `ValueError` to surface typos early. Unpicklable push payloads raise `PushPayloadNotPicklable` eagerly from `schedule()` so issues surface at the call site rather than on the next restart. Corrupt on-disk records are quarantined-and-logged; the runner never crashes on resume. Live `AgentSession` objects stay in memory and are rehydrated lazily by the history provider on the next turn. - New modules: `_persistence.py` (lock + normalisation), `_state_store.py` (session-bookkeeping store). - Runner rewrite: 4-state model (`pending` / `succeeded` / `failed` / `cancelled`); the transient `running` state was a bug that caused resume to skip records that crashed mid-handler. - New tests: `test_runner_disk.py` (8 tests), `test_host_disk.py` (8 tests). 194 passed total. pyright + mypy + ruff clean. - README: new "Optional disk persistence" section with code samples. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * feat(hosting): add checkpoints to state_dir + fix host docstring Three related polish changes on top of the disk-persistence landing: 1. Extend `state_dir` to cover workflow checkpoints. Adds `checkpoints` as a third `HostStatePaths` key. Single-path form (`state_dir="/foo"`) now also auto-derives `/foo/checkpoints/` for workflow targets (equivalent to passing `checkpoint_location="/foo/checkpoints"`). The mapping form lets workflow callers opt out by omitting the key, or route checkpoints to a different volume. Conflict / precedence rules: * Explicit `checkpoint_location` always wins over the state_dir derived path; a warning surfaces the double-config. * Single-path `state_dir` + non-Workflow target → checkpoints path silently ignored (no eager directory creation either). * Mapping form with `checkpoints` + non-Workflow target → warn (almost certainly dead config). * Derived path with a workflow that already has its own `checkpoint_storage` → same `RuntimeError` as the explicit parameter triggers, so ownership stays unambiguous. Checkpoint persistence uses `FileCheckpointStorage` from the framework core — no extra dependency. Only `runner` and `sessions` require the `[disk]` extra. 2. Move `AgentFrameworkHost.__init__` parameter docs from `Args:` to `Keyword Args:` for every parameter after the `*`. Only `target` remains under `Args:`. Brings the docstring in line with the actual signature (the params have always been keyword-only). 3. `HostStatePaths` already existed as a TypedDict but did not cover `checkpoints`; updated to document the new key with the same per-attribute docstring style as `runner` / `sessions` so editors can surface help on the keys. Validation: 201 tests pass (was 194; +7 checkpoint integration tests in test_host_disk.py). pyright + mypy + ruff + bandit clean. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * feat(hosting): add core IdentityLinker authorization seam Fold the core IdentityLinker pieces into the hosting-core PR so the authorization surface no longer has a deferred Wave-2 placeholder. Provider-specific linkers (for example Entra OAuth helpers) can now plug into core without core depending on an IdP SDK. Core additions: - Add LinkChallenge, LinkedIdentity, LinkResolution, and IdentityLinker. IdentityLinker.resolve(identity) is a single-call decision that returns either a linked identity with verified claims or a challenge the channel can render. - Enable LinkedClaimAllowlist end-to-end. It now abstains pre-link and allows/denies post-link against verified claims, including multi-valued claims such as groups. - Add AuthPolicy factories for common allowlist shapes. - Extend Allowed with verified_claims and claim_source for audit/telemetry without requiring callers to re-derive how the decision was made. Host behavior: - identity_linker is now typed as IdentityLinker | None. - authorize() supports open, native-id, forced-link, and linked-claim profiles end-to-end. - require_link=True resolves via the linker and returns LinkRequired when the identity is not linked. - claim-based allowlists use channel-emitted verified_claims when present, or linker-resolved claims otherwise. - authorize() remains decision-only and does not mutate _identities/_active; identity registry writes remain on the actual request execution path. Docs/tests: - Remove Wave-1/Wave-2 language from core/spec/ADR surfaces touched here. - Update the spec/ADR to describe the core linker seam and provider-specific linker packages. - Add authorization tests for linker challenges, linked identities, linked claim allowlists, channel-emitted claims, AuthPolicy factories, and the no-mutation contract. Validation: 214 tests pass, pyright/mypy/ruff clean. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * feat(hosting): add link-store path to state_dir Identity linking introduces host-adjacent state that needs the same state_dir treatment as runner, session, and checkpoint state. Add a links component to the host state paths so applications and linker packages have a typed, discoverable persistence location. Changes: - Extend HostStatePaths with links and include it in state_dir normalization (state_dir/links/ for the single-path form). - Add SupportsLinkStorePath, an optional protocol for identity linkers that accept a host-provided link-store path. - AgentFrameworkHost now offers state_dir links to compatible linkers, warns when an explicit links path is supplied without a linker, and warns when the configured linker manages persistence directly instead of implementing SupportsLinkStorePath. - Update README and spec text to document the link-store component and clarify that concrete linkers still own the storage format. - Add disk-state tests for compatible, missing, and non-configurable linkers. Validation: 217 tests pass, pyright/mypy/ruff clean.

Python: Shell tool with support for local and Docker (#5664)
* 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. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * 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. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * 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(). Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * 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. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * 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. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * 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. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * 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. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * 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. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * 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. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * 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' Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * 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) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * 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. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * 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. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * 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.

Python: feat(a2a): use non-streaming transport and return_immediately for background ops (#5963)
* feat(a2a): use non-streaming transport and return_immediately for background ops When stream=False, use a client configured with streaming=False so the SDK sends a single HTTP POST to message/send instead of opening an SSE connection via message/stream. This matches the A2A protocol's design: non-streaming calls use direct request/response, streaming calls use Server-Sent Events. Also sets return_immediately=background on SendMessageConfiguration so the server respects the caller's intent for background operations. Changes: - Create separate streaming and non-streaming internal clients (sharing the same httpx connection pool) to match protocol transport semantics - Select non-streaming client for run(stream=False) calls - Add SendMessageConfiguration with return_immediately=background - Fallback to streaming client when non-streaming unavailable (e.g. user provides their own client via constructor) - Add tests for client selection and return_immediately behavior Resolves microsoft/agent-framework#5936 Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * fix: address PR review feedback - Initialize last_request in MockA2AClient.__init__ for explicit state - Use 'is not None' instead of truthiness for _non_streaming_client check - Assert return_immediately propagates through non-streaming client path Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * fix: only set configuration when background=True Only attach SendMessageConfiguration to the request when background=True, keeping requests minimal and preserving server-side defaults for normal (foreground) operations.

Python: feat(foundry): add experimental hosted tool factories on FoundryChatClient (#5958)
* feat(foundry): add experimental hosted tool factories on FoundryChatClient Adds eight new `@experimental` static factory methods on `FoundryChatClient` covering Foundry-hosted tools that previously had no helper: - get_azure_ai_search_tool - get_sharepoint_tool - get_fabric_tool - get_memory_search_tool - get_computer_use_tool - get_browser_automation_tool - get_bing_custom_search_tool - get_a2a_tool All factories are marked with the new `ExperimentalFeature.FOUNDRY_TOOLS` tag and resolve the underlying `azure-ai-projects` preview classes lazily through a `_require_sdk_class` helper so older SDK versions still import cleanly and fail with a clear `ImportError` only on use. Tests cover each factory's return type and field wiring, the experimental metadata, and the missing-SDK-class fallback. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * test(foundry): address review comments on tool-factory tests * Skip preview-tool tests gracefully (`_skip_if_sdk_class_missing`) when the installed `azure-ai-projects` does not expose the required preview class, matching the lazy-import guard in production code so the test suite stays green on older SDK installs. * Add `filterwarnings("ignore::FutureWarning")` to each new tool-factory test (and the parametrized metadata test) so they remain stable under strict warning configurations \u2014 the global dedup in `_feature_stage._WARNED_FEATURES` makes `pytest.warns` brittle across ordered runs. * Use `monkeypatch.setattr(..., None, raising=False)` instead of `delattr` in the missing-SDK-class test so it works for modules that implement PEP 562 `__getattr__`. * Split the long `get_bing_custom_search_tool` return into two lines for readability. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * fix(foundry): harden tool-factory kwargs against silent override * Reorder the dict-literal kwargs assembly in get_azure_ai_search_tool, get_memory_search_tool, and get_bing_custom_search_tool so explicit parameters always take precedence over **kwargs (matching the safe pattern already used in get_a2a_tool). This prevents a caller passing `project_connection_id`, `index_name`, `memory_store_name`, `scope`, or `instance_name` through `**kwargs` from silently overriding the explicit security-sensitive arguments. * Update the README experimental note to reflect once-per-feature-id dedup semantics of `_feature_stage._WARNED_FEATURES` rather than claiming a per-factory "first use" warning. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * feat(foundry): split FOUNDRY_TOOLS / FOUNDRY_PREVIEW_TOOLS, add bing-grounding - Add ExperimentalFeature.FOUNDRY_PREVIEW_TOOLS to distinguish wrappers around preview Foundry SDK tool classes (Sharepoint/Fabric/Memory/ComputerUse/ BrowserAutomation/BingCustomSearch/A2A) from FOUNDRY_TOOLS, which is for GA-SDK wrappers that are simply new in agent-framework-foundry (AzureAISearch, BingGrounding). - Add get_bing_grounding_tool factory and a 'Choosing a web grounding tool' comparison block on get_web_search_tool / get_bing_grounding_tool / get_bing_custom_search_tool docstrings. - Drop the _require_sdk_class lazy resolver: every guarded class is available at azure-ai-projects>=2.1.0 (the package floor), so import them eagerly. Concrete return types replace 'Any'. - README: split the experimental factories into two tables, one per feature flag, with a note explaining the distinction. - Tests: split into FOUNDRY_TOOLS / FOUNDRY_PREVIEW_TOOLS factory cases; drop the obsolete missing-SDK-class ImportError test.

Python: Show more authentication methods in Foundry Toolbox MCP (#5719)
* Show more authentication methods in Foundry Toolbox MCP * Remove hardcoded toolbox version num * Add Foundry MCP OAuth consent handling * Use message instead of the dedicated item type * Go back to using OAuthConsentRequestOutputItem * WIP: sample testing * Update error code * Address review on Foundry Toolbox MCP samples Reviewed feedback addressed: - Drop the branch-pinned `git+https://...@feature/...` entries from `04_foundry_toolbox/requirements.txt`; restore the simple comment + `mcp` runtime dep. The git pins were only useful while iterating on the PR and shouldn't ship. (eavanvalkenburg) - Fix the `/toolsets/` typo in both `04_foundry_toolbox/README.md` and `06_files/README.md`. Verified empirically against the research_toolbox in the test workspace: the toolbox MCP gateway lives at `/toolboxes/{name}/mcp?api-version=v1` and requires the `Foundry-Features: Toolboxes=V1Preview` header. `/toolsets/{name}/mcp` returns 403 with `preview_feature_required: Toolsets=V1Preview` (a different opt-in feature). - Wrap `httpx.AsyncClient(...)` in `async with ... as http_client:` in both samples so the connection pool is cleaned up. (Copilot reviewer) - Make the `TOOLBOX_NAME` env var consistent in both samples. Previously the tool name silently fell back to `"toolbox"` when `TOOLBOX_NAME` was unset, but `resolve_toolbox_endpoint()` still required `TOOLBOX_NAME` and would raise `KeyError`. The samples now resolve the endpoint once and derive the tool name from the resolved URL when `TOOLBOX_NAME` isn't set, so the local tool name always matches the upstream toolbox identity regardless of which env var the user set. (Copilot reviewer) - Rename `_responses.is_consent_error` to `consent_url_from_error`: the helper returns `str | None` (the consent URL), not a bool, so the new name matches behavior. Update the test class accordingly. (eavanvalkenburg) - Tighten `_handle_inner_agent`'s lazy-entry catch from `Exception` to `AgentFrameworkException`, the type the MCP layer actually wraps consent errors in via `MCPStreamableHTTPTool.__aenter__` → `ToolExecutionException(inner_exception=mcp_error)`. Network failures, cancellations, and other non-framework exceptions now propagate normally instead of being briefly caught and re-raised. The test helper `_make_consent_error` is updated to use `ToolExecutionException` so it matches the real-world wrapping. (eavanvalkenburg) - Clarify the `github_pat` description in `agent.manifest.yaml` to note it's only needed when the PAT-based connection (`github-mcp-pat-conn`) is chosen; users selecting the OAuth2 connection (`github-mcp-oauth-conn`) can leave it empty. (Copilot reviewer) Validation: ran both samples end-to-end against a real Foundry toolbox (`research_toolbox`) -- the samples connect successfully and the agent lists the toolbox's MCP tools (`api_specs___fetch_azure_rest_api_docs`, etc.). `uv run poe test -P foundry_hosting` passes (119 tests), pyright + mypy clean.

[BREAKING] Python: Enable instrumentation by default (#5865)
* Enable instrumentation by default * Update samples * Optimization when span is not recording * Address Copilot comments * Revert uv.lock * Add warning * Formatting * Fix mypy * Add disable_instrumentation() with sticky user-intent semantics Add a public disable_instrumentation() entry point so users can explicitly opt out of Agent Framework telemetry, with a sticky-disable flag that makes the user's intent "leading" — no framework code path (foundry's configure_azure_monitor, configure_otel_providers, enable_instrumentation, enable_sensitive_telemetry, or direct OBSERVABILITY_SETTINGS.enable_* writes) can re-enable instrumentation until the user explicitly clears the disable with enable_instrumentation(force=True) / enable_sensitive_telemetry(force=True). Also addresses the two remaining unresolved review threads on the PR: 1. test_observability_settings_defaults_instrumentation_true pins the new "ENABLE_INSTRUMENTATION defaults to True when env unset" behavior. 2. test_enable_instrumentation_reads_env_sensitive_data restores coverage for the post-import load_dotenv() fallback path. Implementation: - ObservabilitySettings.enable_instrumentation / enable_sensitive_data become properties backed by _enable_*. While _user_disabled is True, the getters return False and the setters drop True writes (defense in depth so third- party writes can't subvert the disable). - Public is_user_disabled read-only property lets integrations (e.g. foundry's configure_azure_monitor) cheaply check the disable state without poking at privates. - enable_instrumentation() and enable_sensitive_telemetry() short-circuit with an info log when disabled; gain a force=True kwarg that clears the disable. - configure_otel_providers() still creates providers / exporters / views so a later force-enable can use them, but logs an info message when called while disabled. - Foundry's FoundryChatClient.configure_azure_monitor and FoundryAgent.configure_azure_monitor early-return when the user has disabled, so Azure Monitor's global providers aren't installed unnecessarily. Tests: 11 new tests covering default-on, env re-read at call time, sticky behavior against each re-enable surface (enable_instrumentation, enable_sensitive_telemetry, configure_otel_providers, direct attribute writes), force=True override, re-arming the disable, and the __all__ export. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * docs: document disable_instrumentation() and force=True paths Add a "Disabling instrumentation" section to the observability sample README that walks through: - The distinction between the ENABLE_INSTRUMENTATION env var (initial, non-sticky) and disable_instrumentation() (process-wide, sticky). - Why the sticky semantics matter: framework integrations like FoundryChatClient.configure_azure_monitor() can call enable_instrumentation() as part of their setup, and the user's opt-out needs to win. - All five surfaces guarded by the sticky disable (property reads, public enable functions, configure_otel_providers, direct attribute writes, is_user_disabled-aware integrations). - The force=True escape hatch on both enable_instrumentation() and enable_sensitive_telemetry(). - How third-party integrations should consult OBSERVABILITY_SETTINGS.is_user_disabled. - The limits of the disable (does not tear down existing providers / in-flight spans / third-party instrumentation, does not persist across processes). Cross-links the new section from the ENABLE_INSTRUMENTATION row in the env vars table. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * docs: soften disable_instrumentation() overclaim about telemetry guarantees Replace 'no telemetry will be emitted no matter what' (which is too strong, since callers can still pass force=True or mutate private attributes) with language framing the disable as a user-intent contract that library and framework code is expected to honor: the framework actively short-circuits the public enable paths, force=True and private-attribute writes are acknowledged as out-of-contract escape hatches that integrations should not use on the user's behalf. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * docs: correct observability Dependencies section - opentelemetry-sdk is no longer a hard dependency; it is lazily imported by create_resource(), create_metric_views(), and configure_otel_providers() with a clear ImportError when missing. Day-to-day instrumentation works with opentelemetry-api alone provided some other component configures the global OpenTelemetry providers (Azure Monitor, an APM agent, application bootstrap, etc.). - opentelemetry-semantic-conventions-ai is no longer used anywhere in the source; remove it from the listed dependencies. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * docs: replace stale observability migration guide with current PR's only relevant migration The old guide documented the move away from setup_observability(otlp_endpoint=...) which was an earlier-release API change unrelated to this PR and stale enough that it's more confusing than helpful at this point. Replace it with a short note on the single migration this PR introduces: callers of enable_instrumentation(enable_sensitive_data=True) should switch to enable_sensitive_telemetry(). Cross-link to the Disabling instrumentation section for the rare 'force on without enabling sensitive data' use case where enable_instrumentation() still applies.

Python: feat: add agent-framework-monty (Monty-backed CodeAct provider) (#5915)
* Python: feat: add agent-framework-monty (Monty-backed CodeAct) New alpha package that wraps pydantic-monty (a Rust-based Python interpreter) behind the same CodeAct API surface as agent-framework-hyperlight, so users can swap providers with minimal code change. Public API (agent_framework_monty): - MontyCodeActProvider — ContextProvider that injects a run-scoped execute_code tool plus dynamic CodeAct instructions. - MontyExecuteCodeTool — standalone FunctionTool for mixed-tool agents or manual static wiring. - FileMount / FileMountInput / MountMode — public types mirroring the Hyperlight names, with Monty's mode (read-only/read-write/overlay) and write_bytes_limit on FileMount. Constructor kwargs (both classes) mirror Hyperlight where possible: tools, approval_mode, workspace_root, file_mounts; plus a Monty-only resource_limits forwarding ResourceLimits to Monty.start(). Filesystem flow: - workspace_root auto-mounts at /input (read-write), matching Hyperlight. - file_mounts accepts string shorthand, (host, mount) tuple, or FileMount with mode + write cap. - Files written under read-write mounts are scanned post-execution and returned as Content.from_data items (mirrors Hyperlight /output). - overlay mounts buffer writes in-memory; read-only mounts reject writes. Internals: - _monty_bridge.InlineCodeBridge ports the inline (non-durable) bridge from anthonychu/maf-codeact-monty-python; handles FunctionSnapshot / FutureSnapshot pause/resume, dispatches direct typed calls + the call_tool fallback, forwards mount/limits to Monty.start(...). - generate_type_stubs emits per-tool stubs so Monty's `ty` type-checker rejects bad calls before any host tool runs. Alpha-policy compliance (per python-package-management skill): - Added agent-framework-monty = { workspace = true } to root pyproject.toml. - Added row to python/PACKAGE_STATUS.md. - Added monty entry under Experimental in python/AGENTS.md. - NOT added to core[all]; NO agent_framework.monty lazy shim (deferred to beta promotion). Samples (three sets, import from agent_framework_monty directly): - samples/02-agents/context_providers/code_act/monty_code_act.py (provider pattern) + updated local README. - samples/02-agents/tools/monty_code_interpreter/ (standalone + manual-wiring + README). - samples/04-hosting/foundry-hosted-agents/responses/11_monty_codeact/ (full hosted-agent layout with uv-based pyproject.toml + Dockerfile, Azure Monitor wiring via APPLICATIONINSIGHTS_CONNECTION_STRING + enable_instrumentation, ENABLE_INSTRUMENTATION and ENABLE_SENSITIVE_DATA env vars). The alpha wheel is vendored into ./wheels/ (gitignored) via vendor-wheel.sh; new row added to the parent Responses-API README. Tests: - 28 hermetic unit tests (stubbed pydantic_monty). - 18 integration tests marked @pytest.mark.integration, auto-skipped when pydantic_monty is unimportable; exercise the real Monty runtime: print round-trip, last-expression value, direct typed tool dispatch, call_tool fallback, async tool, asyncio.gather parallelism, ty type-check rejection, OS blocked by default, workspace_root read+write capture, read-only / overlay mount semantics, resource_limits.max_duration_secs abort, approval gating end-to-end, full Agent run with a scripted chat client. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Python: fix: monty FileMount test compares against the normalized POSIX path The shorthand string mount goes through _normalize_mount_path, which rewrites Windows drive letters like 'C:\\Users\\...' into '/C:/Users/...' (POSIX-style). The Windows CI runners surfaced this because tmp_path resolves to a backslashed Windows path; the test was comparing against the raw str(host_a) instead of the normalized form. Compare against _normalize_mount_path(str(host_a)) so the assertion is platform-independent. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Python: fix: address PR #5915 review feedback - _execute_code_tool docstring: clarify that the Monty backend supports scoped filesystem access via workspace_root / file_mounts (blocked by default). - _to_monty_mount: import pydantic_monty lazily through load_monty so missing-dependency errors surface as the same actionable RuntimeError the rest of the package raises (not a bare ImportError at module load). Renamed _load_monty -> load_monty for the same reason. - _python_type_repr: emit None for type(None) instead of Any, and normalize both typing.Union[...] and PEP-604 X | Y to PEP-604 syntax so Optional[X] / Union[..., None] / -> None signatures round-trip correctly through ty validation. Added a regression test. - _PrintCollector: track a running character count instead of recomputing sum(len(c) for c in self.chunks) per callback. Eliminates the O(n^2) cost on print-heavy code. - Instructions: mention that the value of the final expression is also returned alongside captured stdout (matches actual behavior). - 11_monty_codeact Dockerfile: pin ghcr.io/astral-sh/uv to 0.11.6 instead of :latest for reproducible builds. - 11_monty_codeact README: replace the bare "see parent README" pointer with sample-specific steps (./vendor-wheel.sh + uv sync + uv run), since the sample uses pyproject.toml + a vendored wheel rather than requirements.txt. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Python: sample: 11_monty_codeact installs agent-framework-monty from PyPI Drop the vendored-wheel scaffolding now that agent-framework-monty is on PyPI as an alpha (1.0.0a*) release: - pyproject.toml: remove [tool.uv.sources] override; keep [tool.uv] prerelease = "allow" so uv pulls the alpha automatically. - Dockerfile: drop the COPY wheels/ step. - README: drop the ./vendor-wheel.sh setup step and the not-yet-on-PyPI warning. - Delete vendor-wheel.sh and the gitignored wheels/ directory. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Python: fix(monty): harden post-execution file capture against symlink escape Same class of issue as the MSRC-reported Hyperlight finding: the post-execution capture walked workspace_root with Path.rglob() + is_file() + read_bytes() - all of which follow symlinks. An attacker who controls the workspace (cloned repo, extracted archive, shared workspace) could pre-place `workspace/leak.txt -> /etc/passwd` or `workspace/outside_dir -> /etc/` and have host files surface as captured Content items. Monty's mount layer already rejects symlink reads from inside the sandbox across all three modes (verified empirically), so the runtime path was safe. This commit closes the post-execution scan path. Changes: - New `_iter_real_files(root)` walker that uses iterdir() + is_symlink() to skip symlinks at every directory level and yields only real files. Replaces the previous `host_root.rglob("*")` calls in both `_snapshot_writable_mounts` and `_capture_written_files`. - Use `Path.lstat()` instead of `Path.stat()` so size/mtime can never be taken from a symlink target. - Three new integration tests reproducing the MSRC attack shape against the workspace_root flow: symlink-to-file outside workspace, symlink-to-directory outside workspace, and a guard ensuring legitimate sandbox writes are still captured when symlinks are present. Per user request, hyperlight is untouched in this commit (separate fix). Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Python: fix(monty): skip symlink regression tests when unsupported Apply the same Windows-CI safety guard as the hyperlight fix in PR #5919: the three symlink integration tests create symlinks via Path.symlink_to(), which fails with OSError / NotImplementedError on unprivileged Windows runners. Add a local _symlinks_supported helper (mirroring the one in packages/core/tests/core/test_skills.py) and pytest.skip when symlinks aren't available, so the tests no longer fail for environment reasons. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Python: fix(monty): address PR #5915 follow-up review feedback - _invoke_tool: drop the inspect.iscoroutinefunction(...) branch and always `await self.tool_map[name](**kwargs)`. Every entry in tool_map is `partial(FunctionTool.invoke, skip_parsing=True)` and FunctionTool.invoke is `async def`, so the branching was dead code - and on Python versions affected by cpython#98590, iscoroutinefunction(partial(bound_async_method, ...)) returns False, causing the bridge to take the asyncio.to_thread path, return an unawaited coroutine, and surface it as a JSON-serialization failure for every tool call. Added a regression test test_invoke_tool_awaits_partial_wrapped_async_method. - generate_type_stubs: skip tools whose name is not a valid Python identifier or is a Python keyword. FunctionTool.name has no upstream validation, so a name like "weird-name" produced a syntax error in the stubs and a name like "broken\n pass\nasync def injected" would inject arbitrary stub source. Non-identifier names stay reachable via `call_tool("weird-name", ...)` at runtime; they just don't get type-checked stubs. Added regression test test_generate_type_stubs_skips_non_identifier_tool_names.

Python: Bump Python package versions for a release (#5964)
* Bump Python package versions to 1.5.0 for a release * Promote orchestrations to 1.0.0rc1 * ci(python-setup): merge dynamic exclude into existing workspace exclude The python-setup action injected exclude = [...] verbatim into [tool.uv.workspace], producing a duplicate 'exclude' key when the section already had a static exclude. Scope the rewrite to the [tool.uv.workspace] section and append the package to the existing array when present; idempotent if the package is already excluded. * Address Copilot review feedback: raise inter-package floors to 1.5.0 - foundry, foundry-local: agent-framework-openai >=1.4.0 -> >=1.5.0 - azure-contentunderstanding: agent-framework-foundry >=1.4.0 -> >=1.5.0 - azurefunctions: pin agent-framework-durabletask to >=1.0.0b260519,<2 Keeps lockstep cohort consistent and avoids mixed 1.4.x / 1.5.0 installs. * Re-include azurefunctions and durabletask in the uv workspace The pinned durabletask>=1.4.0 floor is enough to make resolution succeed; the workspace exclude was over-correction and broke CI samples and pyright type-checking (re-exports in agent_framework/azure/__init__.pyi plus samples/04-hosting/{azure_functions,durabletask}/ could not resolve their imports). Dropping them from agent-framework-core[all] still stands so the metapackage does not pull them. * Restore azurefunctions and durabletask in agent-framework-core[all] The durabletask floor pin keeps users on the safe 1.4.0, so they are once again included in the metapackage. Update CHANGELOG to reflect the pin rather than an [all] removal. * Raise uvicorn ceiling in ag-ui and devui to allow 0.42+ The root override-dependencies pins uvicorn[standard]>=0.34.0 (no upper) and the workspace lock resolves to 0.47.0. The package ceiling <0.42.0 meant the workspace was no longer testing the declared supported range. Bump to <1 so the lock fits within the declared bounds. Also picked up by validate-dependency-bounds: refresh stale orchestrations RC pin in devui dev deps.2026-05-20 09:20:53 +09:00 -
Remove duplicate pop in InMemoryCacheProvider.remove (#5795)
The second self._cache.pop(key, None) call is a guaranteed no-op: the first pop has already removed the key (or returned None), and there is no await between the two statements that could allow another coroutine to re-add it. Removing the dead line clarifies intent without changing behavior.

Python: fix: hyperlight skips symlinks when staging sandbox input (#5919)
* Python: fix(hyperlight): skip symlinks when staging files into the sandbox The helpers that populate the sandbox input tree (``_copy_path`` and the ``_path_tree_signature`` walker used for cache invalidation) relied on ``Path.is_file()``, ``Path.is_dir()`` and ``shutil.copy2`` - all of which follow symlinks by default. When the source tree contains symlinks, that let entries from outside the configured input source surface inside the sandbox. Harden both code paths to never follow symlinks: - ``_copy_path`` now bails out via ``Path.is_symlink()`` before any ``is_dir()`` / ``is_file()`` check, skips non-regular files, and uses ``shutil.copy2(..., follow_symlinks=False)`` as defense in depth. - New ``_iter_real_entries`` walker replaces the previous ``Path.rglob`` call inside ``_path_tree_signature`` (rglob follows directory symlinks). - ``_path_tree_signature`` switches to ``Path.lstat()`` so size/mtime are never read through a symlink target. Added regression tests covering: - A pre-placed file symlink in ``workspace_root`` (top level). - A pre-placed directory symlink in ``workspace_root``. - A nested file symlink inside a real subdirectory. - ``_path_tree_signature`` ignoring symlinks so the cache key reflects only what is actually staged. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Python: fix(hyperlight): address PR #5919 review feedback - _iter_real_entries now yields directories and regular files only, skipping non-regular entries (sockets/FIFOs/devices). Keeps the cache-key signature consistent with what _copy_path actually stages. - The four new symlink regression tests skip when the platform does not support symlink creation (e.g. unprivileged Windows runners), via a local _symlinks_supported helper modelled on the one in packages/core/tests/core/test_skills.py. Prevents OSError / NotImplementedError from failing CI jobs that have nothing to do with the change under test. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Python: fix(hyperlight): address PR #5919 follow-up review feedback - _copy_path docstring: narrow the scope to "symlink entries present in the source tree at rest" and explicitly call out that the copy is NOT atomic with respect to concurrent mutation of the source tree. Callers who need that stronger guarantee should snapshot their workspace before passing it in. Avoids overpromising on a TOCTOU window that pathlib cannot express; closing it properly would need fd-based traversal (O_NOFOLLOW | O_DIRECTORY + os.scandir(fd)) with a separate Windows story, which is out of scope for this targeted fix. - _path_tree_signature: drop the `if path.is_symlink(): return ()` short-circuit. Resolve a symlink root to its real target before walking instead. The public construction flow already resolves workspace_root / file_mounts[].host_path up front so this never affected user-facing code, but the short-circuit was misleading and would have produced an empty, stable signature for any direct caller that builds a _RunConfig without going through the public constructor. Defense in depth: even if a future call site forgets to resolve the root, the cache key still reflects real contents. - Added regression test test_path_tree_signature_walks_through_symlinked_root: a symlinked workspace root must produce a non-empty signature, AND the signature must change when the real target's contents change so the cache key actually invalidates.

Empirically the Azure Responses API returns the deployment alias in body.model and the actual snapshot (e.g. gpt-5-nano-2025-08-07) in this header. - Move the AZURE_OPENAI_SERVED_MODEL_HEADER constant out of observability.py and into RawOpenAIChatClient (as the SERVED_MODEL_HEADER ClassVar). The header is Azure-OpenAI-Responses-API-specific so observability does not need to know about it. - Revert the streaming text_format path to client.responses.stream(...) and drop the _pydantic_model_to_text_format_param helper. That helper imported from openai.lib._parsing._responses (a private SDK path) and the swap to responses.create(stream=True) dropped client-side output_parsed for structured-output streaming. The streaming-with-text_format path is the only one that does not surface the served-model header - documented inline. - Wrap the raw streaming responses in async with so the underlying socket closes deterministically (continuation_token retrieve + create paths). - Fix the empty-string / whitespace-only header at the source by stripping in _extract_served_model and returning None when nothing remains. - Revert unrelated formatting-only churn in _skills.py and test_mcp.py. - Update unit tests to assert against chat_response.model / update.model and add an aggregated streaming assertion plus a pin that the streaming-with-text_format path does not get the header. Verified end-to-end against Azure OpenAI Responses API: deployment alias gpt-5-nano now reports gpt-5-nano-2025-08-07 as ChatResponse.model in both the non-streaming and streaming paths.

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 from394bcd607remains. 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.

Python: Parse YAML block scalars in SKILL.md frontmatter (#5863)
The frontmatter parser previously matched only single-line `key: value` pairs, so block scalar indicators (`|` literal, `>` folded, with chomping `-`/`+`) were silently truncated to the indicator character. Multi-line descriptions like `description: >\n ...` lost their content. Add `_parse_yaml_scalar_value()` which detects block scalar indicators, collects indented continuation lines, strips the common leading indentation, joins per scalar style (newlines for `|`, spaces for `>`), and applies chomping per the YAML 1.2 spec. Update `_extract_frontmatter()` to use the helper for unquoted values. Adds 15 unit tests covering literal/folded styles, all chomping variants, indentation handling, content containing colons, non-description fields, tab indentation, blank-line preservation, and a regression test for plain values. Fixes #5713. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Python: Support list[str] arguments for file-based skill scripts (#5850)
Port of .NET PR #5475. Broadens the args type from dict[str, Any] | None to dict[str, Any] | list[str] | None across the skill script API surface, enabling CLI-style argv forwarding to subprocess scripts. Changes: - SkillScript.run(), InlineSkillScript.run(), FileSkillScript.run(): widen args type; InlineSkillScript rejects list with TypeError - FileSkillScript.parameters_schema: returns array-of-strings schema - FileSkill.content: appends <scripts> block with parameters_schema - SkillScriptRunner protocol: widen args type - SkillsProvider._run_skill_script: widen args type - run_skill_script tool schema: accept object, array, or null - subprocess_script_runner sample: accept list[str], reject dict - class_based_skill sample: fix missing SkillFrontmatter wrapper - Standardize 'folder' to 'directory' in docstrings (#5712) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

[BREAKING] Python: Align file skill folder discovery with agentskills.io spec (#5807)
* Align Python FileSkillsSource with agentskills.io spec Update FileSkillsSource to scan spec-defined subdirectories instead of recursive rglob for resource and script discovery: - Resources: scan 'references/' and 'assets/' (was: entire skill tree) - Scripts: scan 'scripts/' (was: entire skill tree) - Add resource_directories and script_directories parameters for customization, with '.' root indicator for skill root files - Add directory validation: reject '..' traversal, absolute paths, empty names; normalize separators and deduplicate directories - Non-recursive scanning within each configured directory (top-level only) - Containment check validates files against target directory, not just skill root, for stronger path-traversal defense - Case-insensitive directory deduplication via os.path.normcase() - Cross-platform absolute path rejection in directory validation - Sort discovery results for stable ordering - Update SkillsProvider.from_paths() to pass new parameters through - Update all tests for new subdirectory-scoped discovery behavior Resolves #5711. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Address PR review: tighten path validation and add containment guard - Narrow Windows absolute path check to proper drive-root pattern (re.match r'^[A-Za-z]:[/\\]') to avoid rejecting valid POSIX names - Add _is_path_within_directory guard before _has_symlink_in_path in both discovery methods to prevent ValueError on escaped paths Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Log warning on OSError during directory listing in skill discovery Address review comment: _discover_resource_files and _discover_script_files previously swallowed OSError silently when iterdir() failed.

[BREAKING] Python: DevUI: tighten default access controls and CORS posture (#5740)
* Python: DevUI: tighten default access controls and CORS posture Adjusts the default configuration of the DevUI server so the out-of-the-box posture matches what most callers expect when running locally. Adds explicit opt-outs for callers who need the previous behavior. - DevServer gains auth_enabled and auth_token constructor params; auth is on by default. Auto-generates and logs a token when none provided. - CORS default is an empty allowlist on every host. Callers wanting cross-origin pass cors_origins explicitly. - Streaming /v1/responses no longer sets Access-Control-Allow-Origin directly; CORSMiddleware owns all CORS decisions. - Loopback binds enforce a Host-header allowlist. - /meta moved out of the auth bypass list (was alongside /health and /). - serve() default flipped to auth_enabled=True; passes auth args through to DevServer instead of using env-var indirection. - CLI: --auth opt-in replaced with --no-auth opt-out; --auth-token preserved. - Tests cover the eight behaviors above in test_server.py. * Python: DevUI: address PR review comments - /meta now derives auth_required from self.auth_enabled instead of reading DEVUI_AUTH_TOKEN, so the auto-generated and explicit auth_token paths report correctly. - Reorder middleware so the loopback Host-header allowlist is registered last; Starlette wraps later-added middleware around earlier-added ones, so the host check now runs outermost (before CORS/auth) as intended. - Rework comments to describe the behavior rather than threat scenarios. - Streaming-headers and CORS tests now construct the server with an explicit auth_token and send a Bearer header, so the assertions actually exercise the streaming/CORS path instead of short-circuiting in the auth middleware.

Python: Strip server-issued response item IDs under storage (#3295) (#5690)
Fixes microsoft/agent-framework#3295. When the OpenAI Responses chat client sends a request that carries previous_response_id / conversation_id / conversation, the server already has the prior turn's response items and rejects duplicates with "Duplicate item found with id fc_xxx". The chat client was re-sending them inline whenever the input messages still carried the items in additional_properties (workflow replay, history providers, etc.), which broke any tool-using agent with persistent history. Decisions: - Single chokepoint: _prepare_message_for_openai. When the resulting request uses service-side storage, drop function_call, reasoning, approval-request/response, and local-shell-call items from the wire input. Keep function_result with its call_id; the server pairs it to the prior function_call via that key. - function_result is preserved unconditionally except for the local-shell variant, which carries its own server-issued item id. - No public API change. Wire format change is subtractive and only on requests that would otherwise 400. - Re-pointed the strict-xfail in test_full_conversation.py from #4047 to #3295. Kept xfail because the test asserts executor-level session-id clearing, which is the defense-in-depth half tracked by 3295-03; this slice closes the wire-level half. Files: - python/packages/openai/agent_framework_openai/_chat_client.py: strip rule applied alongside the existing reasoning-item branch. - python/packages/openai/tests/openai/test_openai_chat_client.py: four new tests pin the contract (function_call, approval, local-shell-call stripped under storage; everything kept without storage). Updated pre-existing tests that exercised the storage-on path to either pass request_uses_service_side_storage=False explicitly or assert the new strip behavior. - python/packages/foundry/tests/foundry/test_foundry_chat_client.py: same explicit storage-off opt-in for the inherited test. - python/packages/core/tests/workflow/test_full_conversation.py: re-pointed xfail reason to #3295 and the executor-level follow-up. Notes for next iteration: - 3295-01 (HITL wire-format validation against live OpenAI/Foundry) was not run; it requires the user's API credentials. The PRD design is locked but the empirical confirmation is still pending. If script 3 fails on either provider, this slice may need to be revisited. - 3295-03 (clear service_session_id in AgentExecutor on full-history replay) remains open. After it lands the xfail in test_full_conversation.py can be removed. - pytest was not run in this iteration because uv-based pytest commands required interactive approval. Validation rests on careful reading; next iteration should run the openai + core test suites.

Python: fix: prevent MCP message_handler deadlock on notification reload (#4866)
* fix(python): prevent MCP message_handler deadlock on notification reload When an MCP server sends a notifications/tools/list_changed or notifications/prompts/list_changed notification, the message_handler previously awaited load_tools()/load_prompts() directly. Since the handler runs on the MCP SDK's single-threaded receive loop, this caused a deadlock: load_tools() sends a list_tools request and waits for its response, but the receive loop cannot deliver that response while blocked in the handler. This manifested as a timeout in call_tool(), which then surfaced as "Error: Function failed." to the model instead of the real tool output. The MATLAB MCP server reliably triggers this because it sends a tools/list_changed notification during tool execution. Fix: schedule reloads as background asyncio.Tasks via a new _schedule_reload() helper, freeing the receive loop immediately.

* Python: Add ClassSkill for class-based skill definitions Add ClassSkill abstract base class with decorator-based resource and script discovery, porting .NET's AgentClassSkill (PRs #5027 and #5183) to Python. - Add ClassSkill(Skill, ABC) with instructions abstract property, cached content/resources/scripts properties - Add @ClassSkill.resource and @ClassSkill.script static method decorators for auto-discovery of methods and properties - Extract _build_skill_content() and _create_resource_element() shared helpers from InlineSkill for reuse - Add _discover_marked_members() for scanning class hierarchies - Add _make_method_name() for Python-to-skill name conversion - Add class_based_skill sample (UnitConverterSkill) - Update mixed_skills sample with TemperatureConverterSkill - Add 58 new tests covering ClassSkill, decorator discovery, property resources, inheritance, kwargs forwarding, and duplicate detection - Export ClassSkill from agent_framework public API Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * fix: replace try/except/continue with assignment to satisfy bandit B112 Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * address PR review feedback - Walk cls.__mro__ in _discover_marked_members for inherited property resources - Use inspect.getattr_static for MRO-aware is_property check - Return defensive copies from resources/scripts properties - Raise TypeError on wrong decorator stacking order (@resource above @property) - Log warning instead of silently swallowing descriptor errors during discovery - Validate explicit name= at decoration time via _validate_member_name - Add tests for all of the above Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Fix temperature converter skill: make resource necessary for script Refactor TemperatureConverterSkill so the agent must read the formulas resource (factor/offset) before calling the script, aligning with the volume-converter pattern. - Resource: numeric factor/offset table instead of symbolic formulas - Script: generic linear transform (value * factor + offset) - Instructions: updated to reflect new workflow Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> --------- Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
