Summary

Adds .github/workflows/zizmor.yml, a caller of rubyatscale/shared-config/.github/workflows/zizmor.yml@main (rubyatscale/shared-config#32), and fixes everything zizmor 1.30.1 reports in this repo so the new check starts clean. The same cleanup went into visualize_packs#113 and pks#55.

  • zizmor mode: the default advanced-security: true, so results go to the Security tab and findings don't fail the job. The caller grants contents: read and security-events: write.
  • Pinned to commit SHAs, with the exact version in a trailing comment:
    • actions/checkout v7 → v7.0.1
    • rubyatscale/rubyfmt-action v1 → v1.0.0
    • checkout moves to v7.0.1, the version shared-config pins. Unless noted below, the rest stay on the release their floating tag runs today.
  • persist-credentials: false on 1 checkout, so the token isn't left in .git/config.
  • Documented ignores for the org's deliberate patterns, worded as in the other repos:
    • unpinned-uses on the @main calls into shared-config, which exist so its fixes propagate.
    • secrets-inherit on secrets: inherit to shared-config. Its workflows declare no workflow_call secrets, so inherit is the only way to pass them.
    • dangerous-triggers on the workflow_run CD trigger, the org's deploy-after-CI-passes pattern.
  • Dependabot: a 7-day cooldown on every entry, plus a github-actions entry to keep the new pins current.

Test plan

  • zizmor 1.30.1 with online audits: 11 findings before, 0 after.
  • actionlint reports nothing new.
  • Fresh Eyes local review: no findings.
  • zizmor / zizmor and the existing checks pass on this PR.

You are seeing this message because GitHub Code Scanning has recently been set up for this repository, or this pull request contains the workflow file for the Code Scanning tool.

What Enabling Code Scanning Means:

  • The 'Security' tab will display more code scanning analysis results (e.g., for the default branch).
  • Depending on your configuration and choice of analysis tool, future pull requests will be annotated with code scanning analysis results.
  • You will be able to see the analysis results for the pull request's branch on this overview once the scans have completed and the checks have passed.

For more information about GitHub Code Scanning, check out the documentation.

Adds a zizmor workflow that calls rubyatscale/shared-config's reusable
zizmor.yml, and fixes what zizmor 1.30.1 reports here so it starts
clean.

Actions are pinned to commit SHAs with the exact version in a trailing
comment: checkout at v7.0.1, as shared-config pins it, and the rest at
the release their floating tag runs today. Checkouts set
persist-credentials: false. The @main calls into shared-config, secrets:
inherit and the workflow_run CD trigger get the same documented zizmor
ignores the other rubyatscale repos use. Dependabot entries get a 7-day
cooldown, and a github-actions entry keeps the new pins current.
