No issue — this came out of the release run for 98c0121cd, which failed on its push to changeset-release/main.

Problem

pnpm install runs prepare: simple-git-hooks, which reinstalls this repo's local pre-push gate inside the release job. Every git push the changesets action makes therefore re-ran the whole suite in CI: 20,387 tests, 1030 seconds, on a commit CI had already tested — wait-for-checks blocks the job on exactly that.

That is what failed the last run. The push held its lease for the full 17 minutes and was rejected:

! [remote rejected] HEAD -> changeset-release/main
(cannot lock ref 'refs/heads/changeset-release/main': is at faf98e82a but expected bf1c7266c)

That instance was harmless — the branch already had the right content from the run before it. The publish path is not. There, the same push carries the version tags and runs after npm has already accepted the packages. One flaky test under runner load, or the 30-minute job timeout, would leave a published release untagged and skip every job that depends on it: docs, native artifacts, the VS Code extension, the Homebrew tap, the CDN. The failed run already demonstrated that skip cascade.

The job also sat at 21 of its 30 allotted minutes, almost all of it re-running tests.

What changed

Two independent layers, because either alone has a gap:

  • SKIP_HOOKS: "1" at the workflow level.scripts/pre-push.sh reads it and stands down. Set on the workflow rather than a step so it reaches the pushes a JS action spawns, and so it survives a hook being reinstalled.
  • Deleting the hooks after install, with a check. This does not depend on the environment surviving that hop. It runs afterpnpm install, because install is what puts the hooks back. It resolves the directory with git rev-parse --git-path hooks — git's own resolution of core.hooksPath — rather than assuming .git/hooks, and fails the job if a hook is still present afterwards.

Also documented the concurrency behaviour that shaped this: not cancelling in-progress runs is deliberate (never interrupt a publish), but GitHub holds only one pending run per group, so a third push while a release is running silently drops the one queued behind it. A short release job is what keeps that window small — which matters more now that the release PR can merge on a cadence.

Verified the guard against a default hooks dir, a custom core.hooksPath, and a mutation where removal is defeated — the last one fails the step, as intended. shellcheck clean.

Checklist

  • I have read the CONTRIBUTING document.
  • I have linked a related issue (external PRs: the issue must have a maintainer's /approve).
  • I have added tests that prove my feature works. (The step verifies its own effect and fails the job if a hook survives; checked locally against a default hooks dir, a custom core.hooksPath, and a mutation that defeats the removal.)
  • Ran gen-changesets skill, or this PR needs no changeset.
  • Ran gen-docs skill, or this PR needs no doc update.

Summary by CodeRabbit

  • Chores
    • Hardened release automation by applying least-privilege permissions by default.
    • Added explicit read-only permissions where required for release verification, CDN redeployment, Homebrew updates, and native artifacts.
    • Improved safety when removing release-related Git hooks by handling paths securely.

`pnpm install` reinstalls this repo's local pre-push gate, so every push the
release job makes re-ran the whole suite inside CI — 20,387 tests, 17 minutes,
on a commit CI had already tested. That is what failed the last release run:
the push held a stale lease for the whole window and was rejected.
On the publish path the same push carries the version tags and happens after
npm has already accepted the packages. One flaky test there, or the 30-minute
job timeout, would leave a published release untagged and skip every job that
follows it — docs, native artifacts, the extension, the tap, the CDN.
Two independent layers: SKIP_HOOKS, which the hook reads and which reaches the
pushes a JS action spawns, and deleting the hooks after install, which does not
depend on the environment surviving that hop. The delete resolves the hooks
directory through git rather than assuming .git/hooks, and fails the job if a
hook is still there afterwards.

📝 Walkthrough

Walkthrough

The release workflow now defaults jobs to empty GitHub token permissions, grants required read-only permissions, and safely removes and verifies Git hooks after installation.

Changes

Release workflow controls

Layer / File(s)Summary
Release permission controls
.github/workflows/release.yml
The workflow defaults to empty token permissions. CDN verification, Homebrew updates, and native artifact jobs declare required read-only permissions. CDN redeployment declares empty permissions.
Post-install hook enforcement
.github/workflows/release.yml
The release job resolves Git’s hooks directory, removes pre-push and pre-commit hooks with rm --, and fails if either hook remains.

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

Merge Risk:⚪ Minimal · up to d9eb5

This change prevents release pushes from re-running the full test suite, reducing release-job delay and timeout risk. No actionable merge-blocking risk remains after normal checks and review.

Two review findings on this workflow.
The workflow had no top-level `permissions`, so any job without its own block
inherited whatever the repository or organisation hands out, which can be
write-capable. It now denies everything by default and each job asks for what
it needs: `contents: read` for the three that only check out, nothing at all
for the CDN trigger, which posts to a webhook and never calls the API. The
reusable native build declares `contents: read` for itself, so its caller now
grants exactly that.
The hook removal passed a resolved path straight to `rm`. A `core.hooksPath`
beginning with a dash would have been read as options; `--` ends parsing.
