pull_request:No job timeout · Code Checks
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: 15No path filters on triggers · Code Checks
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.

`upload-artifact` has no `retention-days`, so artifacts keep up to 90 days (storage cost). Set e.g. `retention-days: 7`.

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`.

The matrix expands to many parallel jobs per run, multiplying billable minutes, often more combos than you need. Trim the axes, or use `include:` to list only the combinations that matter.
