No job timeout · CodeQL Advanced
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 · CodeQL Advanced
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) · CodeQL Advanced
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-latestScheduled workflow runs in forks · CodeQL Advanced
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'`.
jobs:
nightly:
if: github.repository == 'owner/repo'

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.
