eslint/eslint - GitHub Actions cost & CI smells

From the depmedic OSS benchmark dataset. Source: public workflow YAML in eslint/eslint/.github/workflows.

Numbers are modeled: 8 minutes per priced job, 30 runs per day per workflow, 30-day month, GitHub-hosted runner rate sheet. eslint/eslint's real run frequency is unknown to me. Smells, however, are real - they come from parsing the actual YAML.

What you can do

If you maintain eslint/eslint or a similar workflow shape, three patterns probably move the most dollars per minute of work:

  1. Add a concurrency: block with cancel-in-progress: true on every PR-triggered workflow.
  2. Set timeout-minutes on every job (default is 6 hours).
  3. Make sure every setup-* action sets cache: <ecosystem>.

Free CLIs that automate the audit and the pin step:

npx ci-doctor             # 14-rule audit
npx ci-doctor --fix       # auto-apply the four safe fixes
npx pin-actions           # pin every uses: ref to a SHA
npx gha-budget            # estimate per-run $ + monthly
