What

Give dev-kit's own workflows the token-permissions hygiene it asks of consumers, extend the
action-pin check to .github/actions/, and document setup-nix for new repos.

Part of opendefensecloud/artifact-conduit#441

Why

Three of seven workflows had no top-level permissions: — the same Token-Permissions gap
that was closed in solution-arsenal (17/17) and artifact-conduit (16/16) but never here.
It matters more in dev-kit: docs/NEW_REPO.md tells people to copy these workflows, so the
gap propagates to every new repo.

The pin check had a matching blind spot. Since #30, dev-kit ships an action containing two
third-party SHA pins, and both the path filter and the grep root stopped at
.github/workflows/ — so the repo that defines the pin standard did not apply it to itself.

Testing

  • Ran the widened check against the tree: passes, and now covers
    .github/actions/setup-nix/action.yml.
  • actionlint clean; all workflow and action YAML parses.

Notes for reviewers

  • Latent bug fixed in passing: the check used grep -rE, and -r prefixes each output
    line with its filename, so the next filter — grep -vE '^\s+(- )?uses: \./', the
    local-action exclusion — could never match. Any uses: ./ would have been reported as
    unpinned. Harmless so far (dev-kit references no local actions), but widening the scan
    made it worth correcting. Solar's copy already uses -rhE; this aligns them.
  • issues-add-to-project gets job-level permissions: {} — it authenticates with
    ADD_TO_PROJECT_PAT, so GITHUB_TOKEN needs no scopes. issues-add-labels keeps its
    existing job-level issues: write. Placement matches Solar's convention.
  • NEW_REPO.md: adds the Cachix org secrets to §4, update-action-pins.yml to the §5
    workflow table (also missing), and a "Nix-based CI" subsection with the setup-nix caller
    snippet and the fork-PR read-only note.
  • README.md: the setup-nix example said # v2.1.0, which is the envtest-sideload
    release (feat: provide envtest binary sideloading #29) — cut before feat: add setup-nix composite action #30 merged, so it does not contain the action. Now # <tag>.
  • No Renovate config added — dev-kit is the only repo without one, but the reason is unknown
    and that is a separate decision.

Checklist

  • Tests added/updated — n/a, no shell script to test
  • No breaking changes (or upgrade path documented above)
  • Readable commit history (squashed and cleaned up as desired)
  • AI code review considered and comments resolved

📝 Walkthrough

Walkthrough

The pull request adds explicit GitHub Actions token permissions, expands action pin checks to .github/actions, and documents setup-nix, Cachix secrets, and the pin update workflow.

Changes

Workflow and Nix CI updates

Layer / File(s) Summary
Workflow permission controls
.github/workflows/issues-add-labels.yaml, .github/workflows/issues-add-to-project.yml, .github/workflows/update-action-pins.yml
Workflows now define explicit contents: read access. The project job disables the default token scopes.
Action pin coverage
.github/workflows/update-action-pins.yml
The pin check scans .github/ recursively, triggers for .github/actions/**, and updates the suggested fix command.
Nix CI documentation
README.md, docs/NEW_REPO.md
Documentation updates the setup-nix version placeholder and describes Cachix secrets, Nix-based CI, and the pin update workflow.
