Individual skill
securing-github-actions-workflows
This skill covers hardening GitHub Actions workflows against supply chain attacks, credential theft, and privilege escalation. It addresses pinning actions to SHA digests, minimizing GITHUB_TOKEN permissions, protecting secrets from exfiltration, preventing script injection in workflow expressions, and implementing required reviewers for workflow changes.

# Securing GitHub Actions Workflows
## When to Use
- When GitHub Actions is the CI/CD platform and workflows need hardening against supply chain attacks
- When workflows handle secrets, deploy to production, or have elevated permissions
- When preventing script injection via untrusted PR titles, branch names, or commit messages
- When requiring audit trails and approval gates for workflow modifications
- When third-party actions pose supply chain risk through mutable version tags
**Do not use** for securing other CI/CD platforms (see platform-specific hardening guides), for application vulnerability scanning (use SAST/DAST), or for secret detection in code (use Gitleaks).
