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.

Load Only What You Need

• references/actions.md — audits, job gating, matrix reduction, live validation, and workflow-specific fixes.
• references/reporting.md — when the user asks for a before/after efficiency report.
• references/patterns.md — full YAML examples when inline audit commands are not enough.

Core Workflow

1. Measure first

rg -n "on:|concurrency:|paths:|paths-ignore:|strategy:|matrix:|cache:" .github/workflows
gh run list --limit 10
run_id=$(gh run list --limit 1 --json databaseId --jq '.[0].databaseId')
gh run view "$run_id" --log-failed

Look for: missing dependency caches, missing concurrency cancellation, over-broad triggers, duplicate workflow coverage, and expensive jobs that run on every change regardless of scope.
