Waste detected

Biggest wins first, each with the exact config fix.

No concurrency control · Nix

~268 min/mo · ≈$2/mo

Add a `concurrency:` block keyed on branch to cancel superseded runs when devs push twice quickly.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: true

No job timeout · Nix

~0 min/mo

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: 15

No path filters on triggers · Nix

~0 min/mo

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) · Nix

~0 min/mo

macOS bills ~10× and Windows ~2× 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-latest
