Pull request overview
Adds a new Python hosting sample under python/samples/04-hosting/af-hosting/local_responses_harness/ that mirrors the existing Responses-route + AgentState seam, but hosts a harness agent created via create_harness_agent(...) instead of a plain Agent.
Changes:
- Registered the new sample in
af-hosting/README.md. - Added a self-contained sample directory with FastAPI
/responsesroute (app.py), a local OpenAI SDK client (call_server.py), and run/docs scaffolding (README.md,pyproject.toml,storage/.gitignore).

…mple Addresses PR review: disable the harness file-memory and file-access providers so the headless sample doesn't expose file tools or write outside storage/, and correct the app.py docstring to match call_server.py (which takes no prompt argument).

What this adds
A new Python sample,
python/samples/04-hosting/af-hosting/local_responses_harness/, that hosts a harness agent (built withcreate_harness_agent) behind the same helper-first Responses hosting seam used by the existinglocal_responses/sample.Files:
app.py— a module-level FastAPI ASGI app whose target is acreate_harness_agent(...)agent. UsesAgentState+ theagent-framework-hosting-responseshelpers (responses_to_run,responses_session_id,create_response_id,responses_from_run,responses_from_streaming_run) exactly likelocal_responses/app.py, with a native/responsesroute and Hypercorn startup.call_server.py— a plainopenaiSDK client that drives a three-turn conversation (rotatingprevious_response_id) to exercise session continuity.pyproject.toml— mirrorslocal_responses/pyproject.toml([tool.uv.sources]wires the pre-PyPIagent-framework-hosting*packages to the repo).README.md— mirrors the sibling READMEs (what it shows, prerequisites, how to run, production-readiness notes).storage/.gitignore— same session-storage placeholder as the siblings.af-hosting/README.md.The takeaway the sample makes concrete: a harness agent is just an
Agent, so it drops straight into the existingAgentState/ Responses-helper seam. The harness supplies the function-invocation loop, per-service-call persistence, compaction, and todo management on top of a single@tool.Choices I made (issue had no spec)
#6477 has no body and no comments, so I followed the conventions of the existing
02-agents/harness/and04-hosting/af-hosting/samples rather than inventing a new shape:af-hosting/, namedlocal_responses_harness/to match the existinglocal_responses/andlocal_responses_workflow/pair. It reuses that directory's exact layout (app.py+call_server.py+pyproject.toml+storage/).approval_mode="never_require"so a one-shot HTTP request never blocks on human tool approval. Kept todo management and compaction enabled so the target is a genuine harness agent, not a relabelled plainAgent..pyand followedSAMPLE_GUIDELINES.md(AzureCliCredential, over-documented, expected-output comment).Happy to move or rename this (e.g. a top-level
04-hosting/harness-hosted-agent/, or folding it intolocal_responses/as a variant) if maintainers prefer a different structure or scope — glad to adjust.Verification
No cloud credentials were used; this was not run against Azure.
