'This skill covers hardening GitHub Actions workflows against supply.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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). ## Prerequisites - GitHub repository with GitHub Actions enabled - GitHub organization admin access for organization-level settings - Understanding of GitHub Actions workflow syntax and events ## Workflow ### Step 1: Pin Actions to SHA Digests ```yaml # INSECURE: Mutable tag can be overwritten by attacker - uses: actions/checkout@v4 # SECURE: Pinned to immutable SHA digest - uses: actions/checkout@b4ffde65f46336ab88eb53be808477a3936bae11 # v4.1.1 # Use Dependabot to auto-update pinned SHAs …

How to install
mdr add adriannoes/awesome-agentic-ai/securing-github-actions-workflows@sha256:2b97435cc35f746cThe line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
