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 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.
