Use when reviewing GitHub Actions workflow files for security issues, hardening CI pipelines, or assessing supply chain risk in a repository that uses GitHub Actions.
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
# GitHub Actions Supply Chain Assessment ## Overview GitHub Actions workflows run arbitrary code with access to repository secrets and a `GITHUB_TOKEN`. A compromised or repointed action is indistinguishable from a legitimate one — the attack lands silently in your CI logs. This skill provides a structured checklist for assessing and hardening Actions supply chain risk. **Never rely on your knowledge of whether an action version is "safe". Run the checklist.** --- ## Assessment Checklist Work through every workflow file in `.github/workflows/`. For each file: - [ ] Every `uses:` reference is pinned to a full 40-character commit SHA - [ ] Third-party actions (outside the `actions/` and `github/` namespaces) are identified and risk-rated - [ ] A top-level or job-level `permissions:` block is present and minimally scoped - [ ] No `pull_request_target` trigger is used with `actions/checkout` of the PR head (fork poisoning risk) - [ ] No user-controlled input flows unsanitised into `run:` shell commands (script injection) - [ ] A `dependabot.yml` (or Renovate config) exists to keep pinned SHAs current --- ## SHA Pinning ### Why tags are unsafe …

How to install
mdr add habitat-thinking/ai-literacy-superpowers/github-actions-supply-chain@sha256:42ec2da40ac28ccbThe line at the top of this page pins the label git:20260406.60a61ca, 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.
