Important

Merge prerequisite — an admin must swap a required status check, or this PR cannot land.
main requires the context public-repo-hygiene. Moving the job into its own workflow file renames what it reports to hygiene / public-repo-hygiene, so the old context is now reported by nobody and sits permanently pending — this PR is BLOCKED on it today, and after merge it blocks every future PR to main.
Remove public-repo-hygiene, add hygiene / public-repo-hygiene, atomically with the merge. Do not just delete the old entry without adding the new one: that un-gates the hygiene scan on a public repo, which is the thing this PR exists to harden. Details in this comment.

ELI-5

This repo had its own script for catching internal-only references (Linear IDs, Datadog links, private repo names) before they get published. The problem: the script lived in the repo it was guarding, so a PR could edit the script — or just delete the check — and still go green. This swaps it for a shared one that a PR here can't reach.

What changes

  • Adds .github/workflows/public-repo-hygiene.yml — a thin caller for the reusable workflow in Comfy-Org/github-workflows
  • Deletes scripts/check_public_repo_hygiene.py (184 lines)
  • Removes the public-repo-hygiene job from ci.yml

Why, and it isn't really deduplication

Deduplication is real — this repo and its sibling SDK carried the same three-category policy in two languages, and a one-line allowlist fix recently had to be made twice. But the actual reason is tamper-resistance. The old job was:

- uses: actions/checkout@...   # the PR merge ref
- run: <the checker, from the PR's own tree>

So a PR could add a private repo name to the in-tree allowlist and then leak it, green. Or delete the job. A guard a change can edit is not a guard against that change. The reusable loads the checker from the pinned workflows_ref commit, and the known-public allowlist is deliberately not an input — an allowlist a caller can pass is one a PR in the caller repo can widen.

Parity was proven before deleting anything

Run against this tree, the in-tree checker reported clean, and the shared checker reported exactly one finding:

`scripts/check_public_repo_hygiene.py`: possible internal ticket ID: 'TEAM-1234'

That is the example ticket format inside the old script's own doc comment — in the file this PR deletes. With it gone, the shared checker is clean too. So the two verdicts agree on everything that survives the change, and the one difference is explained rather than waved past.

What the pin does and doesn't buy

Worth stating plainly, because it is easy to overclaim and the reusable's own header is careful about it: the pin guarantees the checker comes from the commit the uses: line resolved to. It cannot govern which uses: line runs — a pull_request caller executes its workflow file from the PR head, so a PR that rewrites both the uses: line and workflows_ref runs a different reusable entirely. That is true of every reusable workflow on GitHub.

The control for it is out of band: a branch-protection rule requiring non-author review of .github/workflows/. That control already exists here, which this description previously got wrong — checked against the live config rather than assumed: main has require_code_owner_reviews: true with required_approving_review_count: 1 and dismiss_stale_reviews: true, and .github/CODEOWNERS owns *, so .github/workflows/ is covered and an approval is dismissed if the branch is pushed afterwards. The caveat still stands in the general form — CODEOWNERS alone is not that control, it names reviewers and blocks nothing until a rule requires their approval — and one further limit: enforce_admins is false, so the rule is not enforced for administrators.

So the honest claim for this PR is the narrower one: a PR here can no longer reach the checker or the allowlist through this workflow's inputs. All of the above now lives in AGENTS.md rather than only in this description, which does not survive the merge.

Next

Once merged, this repo gets enrolled in the PUBLIC_REPO_HYGIENE_CALLERS roster so the bump fleet keeps the pin fresh. Without enrolment the pin never moves, which is its own quiet failure mode.

Provenance

  • Authored by: agent-work loop
  • Verified: pytest: 648 passed, 4 skipped; ruff check .: all checks passed; PR CI green on all 10 contexts; no event=merge_group run exists for this PR, so no merge-queue failure to reproduce
  • Deviations: the required-status-check rename is a repo-settings change needing admin rights, so it is not in this diff — flagged in the banner above and recorded as a follow-up for a maintainer

Summary by CodeRabbit

  • CI and Maintenance
    • Moved public-repository hygiene checks to a dedicated automated workflow.
    • Checks now run for pull requests and changes to the main branch.
    • Removed the previous repository-local hygiene check implementation.
  • Documentation
    • Updated contributor guidance to reflect the shared hygiene workflow.
    • Clarified where future allowlist updates should be made.
  • Changelog
    • Corrected repository and issue links in the v0.1.5 changelog.

Replaces this repo's own scripts/check_public_repo_hygiene.py with a thin
caller for the reusable workflow in Comfy-Org/github-workflows, which now owns
both the checker and the known-public allowlist.

The reason is not deduplication, though that is real -- this repo and its sibling
SDK carried the same policy in two languages, and a one-line allowlist fix had to
be made twice. It is that the old job ran the checker out of the PR's OWN
checkout:

  - uses: actions/checkout@...        # the PR merge ref
  - run: Python scripts/check_public_repo_hygiene.py

so a PR could widen the allowlist, or disable the scan outright, and go green.
A guard a change can edit is not a guard against that change. The reusable loads
the checker from the pinned workflows_ref commit instead, and the allowlist is
deliberately NOT an input, so a PR here cannot reach either through this
workflow's inputs.

PARITY PROVEN before deleting anything, not after. Run against this tree, the
in-tree checker reported clean and the shared one reported exactly one finding:
'TEAM-1234' in scripts/check_public_repo_hygiene.py's own doc comment --
the example ticket format, in the file this commit deletes. With that file gone
the shared checker is clean too, so the verdicts agree on everything that
survives.

Note what the pin does and does not buy, per the reusable's own header: it
guarantees the checker comes from the commit the uses: line resolved to. It
cannot govern which uses: line runs, because a pull_request caller executes its
workflow file from the PR head. The control for that is a branch-protection rule
requiring non-author review of .github/workflows/, which is worth having here if
this is ever made a required check.

📝 Walkthrough

Walkthrough

The repository removes its local public-repository hygiene job and checker. A separate workflow delegates hygiene checks to a pinned reusable workflow on pull requests and pushes to main. Related documentation and changelog URLs are updated.

Changes

Public repository hygiene

Layer / File(s) Summary
Reusable hygiene workflow
.github/workflows/public-repo-hygiene.yml, .github/workflows/ci.yml

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to f78c6

The PR replaces the in-tree hygiene check with a reusable workflow, but merge readiness depends on enforcing non-author review for workflow changes and requiring the new hygiene / public-repo-hygiene status check. Without those controls, the hygiene gate could be bypassed or merges could be blocked.

Comment thread AGENTS.md
… check context

The AGENTS.md rewrite claimed the pin meant "a PR here cannot reach it
through this workflow's inputs" and stopped there. True, but a reader
takes it as "a PR cannot subvert the hygiene gate", which is a stronger
claim than the pin supports: `workflows_ref` only has to equal the SHA
the caller's own `uses:` line selected, and a `pull_request` run executes
that workflow file from the PR head. A PR that rewrites both values runs
a different reusable entirely and its equality check proves nothing. The
pinned reusable says exactly this in its own header ("WHERE THAT
GUARANTEE STOPS"); the doc that survives in this repo did not.

So state the limit, then state the control that actually covers it here,
because it is a branch-protection setting and not a file anyone can grep
for: main requires an approving code-owner review and dismisses stale
approvals on every push, and CODEOWNERS owning `*` is what pulls
.github/workflows/ under that rule. Also note it is not enforced for
administrators, and that CODEOWNERS alone would enforce nothing -- it
names reviewers and blocks nothing until a rule requires their approval.
That distinction is the whole failure mode: an adopter who reads
"CODEOWNERS" as sufficient leaves the `uses:` line editable by the very
PR it is meant to gate.

Also record the status-check context the moved job now reports,
`hygiene / public-repo-hygiene`, in both AGENTS.md and CONTRIBUTING.md.
It changed because the job left ci.yml for its own workflow file, and
the old single-segment name is not reproducible for a reusable-workflow
call.

Merge prerequisite: the required status check has to be renamed by an admin, or this PR cannot land

CodeRabbit's outside-diff comment on ci.yml:96 is correct, and it is more than a suggestion — I checked the live branch protection and it is already blocking:

$ gh api repos/Comfy-Org/comfy-python-sdk/branches/main/protection --jq .required_status_checks.contexts
[ "Test (py3.10)", "Test (py3.11)", "Test (py3.12)", "Test (py3.13)",
  "comfy_low codegen drift", "public-repo-hygiene", "build-check (publish dry run)" ]

main requires the context public-repo-hygiene. Moving the job out of ci.yml into its own workflow file renames the context it reports to hygiene / public-repo-hygiene (gh pr checks 68 shows exactly that). The old context is now reported by nobody, so it sits permanently pending.

Two consequences, and the first one is why this is a prerequisite rather than a follow-up:

  1. This PR is blocked on it now. mergeStateStatus is BLOCKED. Every other required context is green, but public-repo-hygiene will never arrive.
  2. Leaving the stale context in place after merge blocks every future PR to main for the same reason. Dropping it without adding the replacement is the other failure — that silently un-gates the hygiene scan on a public repo, which is the exact thing this PR exists to harden.

The fix is a repo-settings change, not a code change, so I have not made it. An admin needs to swap the entry in main's required status checks:

  • remove public-repo-hygiene
  • add hygiene / public-repo-hygiene

Do it atomically with the merge (or immediately after) so there is no window where the hygiene gate is not required.

There is no in-tree workaround worth taking. A reusable-workflow call always reports as <caller job> / <reusable job>, so the old single-segment context is not reproducible from this repo — the closest would be public-repo-hygiene / public-repo-hygiene, which still is not a match. The only other way to keep the old name alive would be a stub job in ci.yml that reports green without running the checker, and a gate that always passes is worse than no gate.

Docs updated in 1d17d95 so the new context name is written down in both AGENTS.md and CONTRIBUTING.md. The settings change itself is recorded as a follow-up for a maintainer with admin rights.

Status: code side is done; two gates left, both human

Addressed

  • CodeRabbit's AGENTS.md:109 finding — fixed in 1d17d95. CodeRabbit confirmed in-thread: "the documented control now states the actual trust boundary. The finding is addressed." Thread resolved.
  • CodeRabbit's outside-diff finding on ci.yml:96 — verified as a real, active blocker rather than a suggestion, written up above and hoisted into the PR description. It is a repo-settings change, so it is not in the diff.
  • Corrected one claim in the PR description that I could not reproduce against the live config: it said a non-author review rule for .github/workflows/ was "worth adding". That rule already exists here (require_code_owner_reviews: true, dismiss_stale_reviews: true, CODEOWNERS owning *). The general caveat still holds and is now in AGENTS.md, along with the enforce_admins: false exemption.

Verificationpytest: 648 passed, 4 skipped. All 11 PR checks green, including hygiene / public-repo-hygiene on the new commit. No event=merge_group run exists for this PR, so there is no merge-queue failure hiding behind the green rollup. Changes are documentation-only; no source or workflow file was touched by this commit.

Two gates remain, neither of which I should clear

  1. CodeRabbit's CHANGES_REQUESTED is stale but still blocking. It acknowledged the fix, then could not re-review: @coderabbitai review and full review both return "Review rate limited — your included review limit is currently reached under the Fair Usage Limits Policy." So the blocking state reflects a quota, not an outstanding finding. It needs either a re-review once quota resets, or a manual dismissal by a maintainer. I have deliberately not dismissed it myself.
  2. @wei-hai's approval was auto-dismissed by my push, since main has dismiss_stale_reviews: true. Re-requested; needs a fresh approval.

And before merge, the required-status-check swap in the description's banner. Not merging this — leaving it for a human.
