Waste detected
Biggest wins first, each with the exact config fix.
No concurrency control · centaur-audit
Add a `concurrency:` block keyed on branch to cancel superseded runs when devs push twice quickly.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: 2 more config fixes with negligible recoverable minutes — timeouts, retention, path filters
No job timeout · centaur-audit
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: 15Full-history clone (fetch-depth: 0) · centaur-audit
checkout fetches the entire git history every run (`fetch-depth: 0`) and nothing in the workflow appears to read it. Remove the line — the default shallow clone is much faster on big repos. Keep it if a step genuinely needs history.
