setupskills/setup/SKILL.md

Verify the actionlint-check hook's runtime prerequisites and configuration for this repository. Use when: 'set up actionlint', 'configure actionlint', 'is actionlint working', workflow lint silently isn't happening, or the hook reported a missing prerequisite. Actions: check (read-only verification, default) | apply (resolve what check found). Re-runnable and safe.
