Where the minutes go (30d)
Waste detected
Biggest wins first, each with the exact config fix.
No concurrency control · pr
Add a `concurrency:` block keyed on branch to cancel superseded runs when devs push twice quickly.
concurrency:
group: ${{ github.workflow }}-${{ github.ref }}
cancel-in-progress: trueAlso found: 13 more config fixes with negligible recoverable minutes: timeouts, retention, path filters
No path filters on triggers · ci
Runs on every push/PR with no `paths:` filter, so docs-only changes still trigger full CI. Add a `paths:` filter if that's common.

pull_request:
paths:
- 'src/**'
- 'package.json'Premium runners (macOS / Windows) · ci
macOS bills ~10x and Windows ~2x a Linux minute. The cost estimate above assumes Linux, so your real spend is higher. Move any job that doesn't need them to `ubuntu-latest`.
jobs:
build:
runs-on: ubuntu-latest # ~10x cheaper than macos-latestenvironment: on a CI job · ci
A test/build job is bound to a GitHub environment, so every run counts as a deployment: PR and deployments-API noise. Use repository secrets or OIDC for non-deploy jobs.
No job timeout · ecosystem_compat_test
No job sets `timeout-minutes`, so a hung step can run to GitHub's 6-hour default. Add `timeout-minutes` to each job.

The schedule fires at minute :00, GitHub's peak window, where scheduled runs get delayed or skipped. Shift to any other minute for the same cadence with less contention.

schedule:
- cron: '44 10 * * 1-5' # was '0 10 * * 1-5' — any non-:00 minute avoids the herdScheduled workflow runs in forks · ecosystem_compat_test
The schedule has no repository guard, so forks that enable Actions inherit the cron and burn their own minutes. Gate the job with `if: github.repository == 'owner/repo'`.
