Missing dependency cache · [ty Playground] Release
Set `cache: 'npm'` on your `actions/setup-node` step, or add an `actions/cache@v4` step keyed on your lockfile.
- uses: actions/setup-node@v4
with:
node-version: 20
cache: 'npm'No concurrency control · Release
Add a `concurrency:` block keyed on branch to cancel superseded runs when devs push twice quickly.

# no cancel-in-progress on deploys: queued deploys would be droppedAlso 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.
on:
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-latestCache without restore-keys · CI
The cache restores only on an exact key match, so any lockfile change means a full cold download. Add a `restore-keys:` prefix line for partial restores.

deps-${{ runner.os }}-No job timeout · Release
No job sets `timeout-minutes`, so a hung step can run to GitHub's 6-hour default. Add `timeout-minutes` to each job.
jobs:
build:
runs-on: ubuntu-latest
timeout-minutes: 15Artifacts at default retention · Release
`upload-artifact` has no `retention-days`, so artifacts keep up to 90 days (storage cost). Set e.g. `retention-days: 7`.
