Practitioner-grade GitHub Actions knowledge: authoring, reviewing, hardening, debugging workflows. Activate when reading or writing `.github/workflows/` files, diagnosing a failing pipeline, reviewing a CI change, or designing reusable/composite actions. Covers caching, secrets, GITHUB_TOKEN, OIDC.
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 A dense, practitioner-oriented skill for working on GitHub Actions workflows. Read the relevant section before editing a workflow file; defer to the `references/` documents for exhaustive syntax tables. Treat the **Security defaults** section as non-negotiable. ## When to activate Activate this skill the moment any of the following is true: - A file under `.github/workflows/**` is being authored, modified, or reviewed. - A composite action (`action.yml` / `action.yaml`) is being changed. - A reusable workflow (`on: workflow_call`) is being designed or consumed. - A pipeline is failing and the root cause is suspected to be in the workflow definition, the runner image, the cache, the permission model, or the secret/variable scoping. - A pull request touches CI configuration and a reviewer-grade audit is required (pinning, permissions, OIDC, secret exposure). - A migration is being planned (e.g., from GitLab CI, CircleCI, Jenkins, or Azure Pipelines to GitHub Actions). - A self-hosted runner fleet is being designed, hardened, or diagnosed. Defer to **security** when the change introduces a new secret, expands …

How to install
mdr add crewrig/crewrig/github-actions@sha256:180d514f5ea1a22cThe line at the top of this page pins the label git:20261018.1588e62, 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.
