GitHub Actions Cost Audit — for DevOps engineers + platform engineers + tech leads at orgs spending >$500/mo on GitHub Actions.
One-shot $79 audit of your repo's .github/workflows/*.yml + Dockerfiles. 10 deterministic patterns: missing actions/cache for npm/pip/cargo/go, no concurrency.cancel-in-progress (5 redundant runs per PR-stack), matrix bloat (macOS where Linux works = 10× cost), fetch-depth: 0 wasted clones, artifact upload bloat, missing concurrency group, docker buildx without GHA cache, schedule too frequent. Before/after YAML diffs paste-able into a PR. Verifiable in github.com/<org>/settings/billing next cycle. Riding Dec 2025 GitHub pricing earthquake (HN #46291156, 639 comments, BuildJet shut down).
