Audit GitHub Actions workflow efficiency and recommend fixes to reduce CI minutes and costs.
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 Efficiency Use this skill as a lean entrypoint for GitHub Actions efficiency work. Inspect the repo, identify the waste source, and load only the reference material needed for the current task. If no workflows exist yet, load [`references/actions.md`](./references/actions.md) and define a baseline before proceeding with the steps below. **If shell or `gh` CLI access is unavailable:** ask the user to paste `.github/workflows/` contents and `gh run list --limit 10` output. If only partial files are provided, note it: "Audit based on provided files only; some insights may be incomplete." Begin responses from files alone with: "**Static-only analysis** (not confirmed with live runs)." ## Use This Skill When - The user wants to reduce GitHub Actions runtime, CI cost, or wasted workflow runs. - The repo has existing workflows in `.github/workflows/` or explicit GitHub Actions configuration questions. - The user asks for caching, concurrency, path filters, matrix reduction, job optimization, or workflow-specific fixes. - The user needs help creating a new GitHub Actions workflow or CI baseline from scratch. ## Load Only What You Need …

How to install
mdr add github/awesome-copilot/github-actions-efficiency@sha256:9c41e860468e5c88The line at the top of this page pins the label git:20260525.12666c9, 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.
