✅ actionlint Action

GitHub - marketplace GitHub - release GitHub - ci GitHub - license

This GitHub Action allows you to quickly and easily run actionlint in your GitHub workflow using native Runner OS without installing 3rd party dependencies. It is based on an official action lint usage proposal from Use actionlint on GitHub Actions together with Problem Matchers.

  • Action is platform-independent and tested on all the latest GitHub-hosted runners (ubuntu-latest, macos-latest, windows-latest).
  • Uses GitHub cache for caching actionlint binaries for faster and more efficient workflow run.
    • 3rd party actionlint dependencies like shellcheck or pyflakes are not cached, but action installs them if not present on the Runner.
