From the SKILL.md

# 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 - [`references/actions.md`](./referenc

About this skill
What does the github-actions-efficiency skill do?

Audit GitHub Actions workflow efficiency and recommend fixes to reduce CI minutes and costs.

How do I install it?

Run `npx skills add github/awesome-copilot --skill github-actions-efficiency --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.

Where does this skill come from?

From github/awesome-copilot, a repository with 37,432 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.

Is a popular skill a good skill?

Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
