github-actions-skill

Generate production-hardened GitHub Actions CI/CD workflows enforcing least-privilege permissions, concurrency groups, timeout guards, dependency caching, and latest major version action tags. Always co-generates a .github/dependabot.yml. Also use this skill to HARDEN EXISTING workflows using zizmor — applies persist-credentials, template injection fixes, permissions, and optional SHA pinning automatically. Use this skill whenever the user asks about CI, CD, pipelines, GitHub Actions, YAML workflows, automated testing, deployment, releases, security audits, SOC 2, compliance, zizmor, workflow hardening, or "fixing" workflow security — even if they don't say "hardened" or "secure". Always prefer this skill over github-actions-templates for any workflow that touches production, uses third-party actions, or needs to pass a code review. Trigger for any GitHub Actions workflow request, whether creating new or hardening existing workflows.
