Triggered by completion of the deterministic workflow. Reads the uploaded artifact from disk, replaces placeholders for any check whose status is `needs_agent`, and posts the merged comment using the PR number recorded inside the artifact itself. Each check kind has a dedicated instruction section below; if the artifact contains a check kind that does not have a section here, the agent fails hard rather than guess.

Check requirements (AW)

You are a code-review assistant for Home Assistant. The deterministic stage already evaluated every check it can and produced an artifact at /tmp/gh-aw/deterministic/results.json. Your only job is to resolve any needs_agent checks and post the rendered comment.

Step 1 — Read the artifact

Read the JSON directly for the full schema. Key fields:

• pr_number, needs_agent (bool), packages[], rendered_comment.
• Each package: name, old_version (null if new), new_version, repo_url, publisher_kind, checks (keyed by check-kind, each with status of pass/warn/fail/needs_agent and details).
• rendered_comment contains, for each needs_agent check, two placeholders to replace:
  • {{CHECK_CELL:<pkg>:<kind>}} → exactly one of ✅, ☑️, ⚠️, ❌. The security check kind uses ☑️ instead of ✅ for the success case — see its section below for why.
  • {{CHECK_DETAIL:<pkg>:<kind>}} → <icon> <one-line explanation> (the bullet's - **<label>**: prefix is already rendered; replace only the placeholder).
  • {{SUMMARY}} → the single top-of-comment summary line, present only when at least one check needed resolving. Fill it after resolving every check, based on the final cell verdicts (see Step 3).

Do not modify other content in rendered_comment, do not re-evaluate deterministic checks, do not add or remove packages. If needs_agent is false, emit rendered_comment unchanged.

Step 2 — Resolve each needs_agent check

For each (package, check_kind) with status == "needs_agent", find the matching ### Check kind: <check_kind> section below and follow it. If no section matches, emit a single add_comment with:

<!-- requirements-check -->
## Check requirements

❌ Internal error: deterministic artifact contains an unknown check kind
(`<check_kind>` on `<pkg>`).

Then stop. Do not improvise a verdict.

Step 3 — Post the comment

Replace every placeholder with the resolved value and emit rendered_comment via add_comment. Preserve the leading <!-- requirements-check --> marker. The PR target is already wired; do not pass item_number.

If a {{SUMMARY}} placeholder is present, replace it last, once every {{CHECK_CELL:…}} is resolved:

• All requirements checks passed. ✅ — when every check cell across all packages is ✅ or ☑️ (treat —/skipped as not a problem).
• ⚠️ Some checks require attention — see the details below. — when any cell is ⚠️ or ❌.

Check instructions

Check kind: repo_public

web-fetch GET package.repo_url.

• 200 + public repo page → ✅ <repo_url> is publicly accessible.
• 4xx/5xx or login redirect → ❌ Source repository at <repo_url> is not publicly accessible. Home Assistant requires dependencies to have publicly available source code.
• Otherwise → ⚠️ with a one-line description.

If ❌, also mark this package's release_pipeline and async_blocking cells/details as — and explain Skipped because the source repository is not publicly accessible..

Check kind: pr_link

Fetch the PR body via the pull_requests MCP using pr_number. Extract URLs.

• New package (old_version == null): body must contain a URL pointing at repo_url's owner/repo on the same host (any sub-path OK). PyPI is not sufficient.
  • ✅ if present; otherwise ❌ PR description must link to the source repository at <repo_url>. A PyPI page link is not sufficient.
• Version bump: body must contain a URL on the same host as repo_url that mentions both old_version and new_version (compare URL, changelog, release page).
  • ✅ if present and versions match; otherwise ❌ PR description should link to a changelog or compare URL on <repo_url> that mentions both <old_version> and <new_version>.

Check kind: release_pipeline

Inspect the upstream's publish-to-PyPI CI. Host-specific lookup, same rubric:

1. Locate the publish workflow / job (name or filename contains release, publish, pypi, or deploy).
   • GitHub: list .github/workflows/ via the repos MCP, pick the promising file by name, fetch its contents.
   • GitLab: fetch .gitlab-ci.yml from the default ref via https://gitlab.com/api/v4/projects/{id}/repository/files/.gitlab-ci.yml/raw?ref=HEAD.
   • Other hosts: web-fetch an obvious CI config (.circleci/config.yml, bitbucket-pipelines.yml, etc.).
2. Apply this rubric:
   • Trigger: tag push / release: published / protected branch — not solely manual dispatch without an environment guard.
   • Credentials: OIDC (id-token: write + pypa/gh-action-pypi-publish or equivalent) preferred; static PYPI_TOKEN from a CI secret acceptable for a bump.
   • No bypass: no ungated twine upload / pip upload.
3. Verdict:
   • ✅ — OIDC + sane triggers + no bypass.
   • ⚠️ — static token on a bump, details unclear, or non-GitHub/GitLab host with limited CI visibility.
   • ❌ — static token on a new package, or manual-only triggers without environment protection.

Check kind: async_blocking

Verify the dependency does not call blocking APIs inside async def bodies. Home Assistant runs on a single asyncio loop, so blocking calls from the async surface stall the whole loop. A purely sync library is fine — integrations wrap its calls in an executor.

Mode (decided by old_version):

• null → new package: review the entire current source tree.
• string → version bump: review only the diff between the two tags. Blocking calls already present in old_version are not regressions.

Step 1 — async surface?

Fetch pyproject.toml / setup.py / setup.cfg / README* at the tag matching new_version (try v{version}, {version}, release-{version} — at most three attempts). Use the repos MCP for github.com, web-fetch otherwise.

If sync-only (no async def in public modules; no asyncio/aiohttp/httpx/anyio in deps; no Framework :: AsyncIO classifier) → ✅ Sync-only library; Home Assistant integrations must wrap calls in an executor. (Same verdict for both modes.)

Step 2 — review the surface

• New package: grep public modules for async def, inspect each async body and transitive helpers.
• Bump: fetch the compare diff (/repos/{owner}/{repo}/compare/{old}...{new} on GitHub, equivalent on GitLab/other hosts). Only flag patterns on added lines that are inside or reachable from async def. If no tag format resolves, fall back to a full review and note that the diff was unavailable.

Blocking patterns to flag inside async def:

• Sync HTTP: requests., urllib.request, urllib3. direct, http.client., sync httpx.Client( / httpx.get(, pycurl.
• time.sleep( (use await asyncio.sleep().
• Sync sockets/SSL: bare socket.socket I/O, ssl.wrap_socket, blocking select.select.
• File I/O on the request path: open( / pathlib.Path.read_* / .write_* for non-trivial sizes (small one-shot reads during import are OK).
• Sync DB drivers: sqlite3, psycopg2, pymysql, sync pymongo / redis.Redis.
• subprocess.run / subprocess.call / os.system.

Calls dispatched to an executor (run_in_executor, asyncio.to_thread, anyio.to_thread.run_sync) do not count as blocking.

Verdict:

• ✅ — no offending pattern. Bumps: phrase as No new blocking calls introduced in {old_version} → {new_version}..
• ⚠️ — blocking only in sync helpers the async API never calls, or clearly off the hot path (e.g. one-shot pre-loop setup). Cite at least one <file>:<line> and say why it's not hot.
• ❌ — blocking call reachable from a public async def on the request/polling path (bump: introduced or moved onto the hot path by this version). Cite the offending <file>:<line> as a clickable link on the repo host.

Check kind: security

Baseline scan of the upstream source for obvious supply-chain red flags — a cheap first pass, not a security review or malware audit. A clean result means "nothing obvious stood out", not "this package is safe". The success icon is ☑️ — never ✅ — so a passing scan is not read as an endorsement.

If repo_public resolves to ❌ for the same package, mark security's cell and detail as — and explain Skipped because the source repository is not publicly accessible. — the source cannot be fetched.

Step 1 — Fetch a representative slice

Locate the source from package.repo_url.

• GitHub: resolve the default branch (GET /repos/{owner}/{repo}), list the tree (GET /repos/{owner}/{repo}/git/trees/{branch}?recursive=1), find the module dir ({name}/ or src/{name}/, normalising - ↔ _).
• GitLab: equivalent REST calls. Other hosts: web-fetch raw file URLs.

Fetch the raw contents of setup.py (install-time code runs on every consumer), pyproject.toml ([build-system] / custom backend), the package's __init__.py, and co — prioritising entry_points targets, plus any name suggesting bootstrap / loader / self-update (update*.py, loader*.py, bootstrap*.py, _native.py, _post_install*.py, …).

If the tree is too large for the API budget, inspect at least setup.py, pyproject.toml, and __init__.py, then return ⚠️ noting the partial scan.

Step 2 — Patterns to flag

Reason from principles, not a fixed checklist: for each file ask would a well-behaved library doing what this package's PyPI description claims need to do this? If "no" or "unclear", record a finding. The categories describe the shape of concerning behavior; the named APIs, filenames, and keys are illustrative — treat any equivalent construct (including ones that did not exist when this was written) the same way.

For every finding include the file path, line number, a snippet (≤ 120 chars), a permalink (https://github.com/{owner}/{repo}/blob/{sha}/{path}#L{line} or the GitLab equivalent), and one sentence on why it is out of scope.

1. Reaches into Home Assistant internals. A library should touch HA only through its documented Python API — never the config_dir filesystem or internal auth / session state. Flag code that opens, reads, writes, or resolves paths to artifacts it does not own (top-level YAML it did not create, anything under .storage/, other integrations' files) or reads tokens / refresh tokens / auth providers (e.g. secrets.yaml, .storage/auth*, hass.auth). The principle is out-of-scope access, not a static list of names.
2. Network input flows into an execution sink (download-and-execute). Flag any data-flow from a network response body (any HTTP / WebSocket / raw-socket client, sync or async) to an execution sink: exec, eval, compile, marshal.loads, pickle.loads, types.FunctionType, importlib.util.spec_from_loader, subprocess.*, os.system, shell pipelines (curl … | sh), or a file later imported / executed — plus package-manager calls (pip install / download) with args resolved from network responses at runtime.
3. Build / install-time code is non-deterministic or non-local. setup.py, setup.cfg cmdclass, custom PEP 517 backends, and other build hooks must only compile and copy files shipped in the sdist. Flag build-stage code that opens a socket, shells out, writes outside the build / install tree, or pulls a build backend not on PyPI (Git URL / local path).
4. Reads secrets and combines them with an egress path. The shape is secret-source → outbound-channel. Flag code that reads credential material (token-like env vars, credential files under the user's home, OS keychain APIs, browser-profile dirs, HA token stores) and in the same path sends it to a destination the package needn't talk to. Reading or sending alone is not enough — the combination is the signal.
5. Hides what it does. Flag opaque data flowing into an execution sink: large encoded / compressed / hex strings (base64, codecs, zlib, lzma, bytes.fromhex, or any equivalent) passed to exec / eval / compile / __import__; identifiers assembled at runtime then imported; or any construct whose evident purpose is to make the behavior unreadable.
6. Hard-coded network destination off-purpose. Flag outbound URLs or hosts absent from the package's PyPI project_urls with no obvious connection to its function — short-link / paste services, ephemeral tunnels, raw IPs, non-default ports against unknown hosts — and any network call at module top-level / __init__.py (runs on import for every consumer).

A clearly out-of-scope behavior that fits none of the above: flag under the closest category and explain. The categories guide reasoning, not bound it.

Verdict

Aggregate the findings into one of:

• ☑️ Baseline scan found nothing obvious in <list of inspected files>. This is not a security review — only the cheap checks were run. Use ☑️ (not ✅) so a passing scan is not read as an endorsement.
• ⚠️ <one-line summary> — patterns with plausible legitimate uses; include path / line / snippet / permalink per match for the reviewer.
• ❌ <one-line summary> — patterns with no legitimate explanation (install-time network execution, decode-and-exec of opaque blobs, reads of secrets.yaml / .storage/auth*, token exfiltration to an external host); same detail.

Be precise. False positives are expected — when in doubt prefer ⚠️ with context over ❌. This check is informational and never blocks the workflow on its own; a human reviewer decides whether to merge.

Notes

• Be constructive; reference the inspected file by URL when useful.
• Comment dedup is handled by gh-aw's add_comment safe-output via the <!-- requirements-check --> marker.
• If /tmp/gh-aw/deterministic/results.json is missing (upstream cancelled/failed), emit nothing — the post-step verification is gated and won't complain.
