Where the minutes go (30d)

Biggest wins first, each with the exact config fix.
No job timeout · Security 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: 15Scheduled at the top of the hour · Security Audit
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.
on:
schedule:
- cron: '45 2 * * *' # was '0 2 * * *' — any non-:00 minute avoids the herdScheduled workflow runs in forks · Security Audit
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'
runs-on: ubuntu-latestNo 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-latestSystem packages reinstalled every run · CI
System packages install from the network on every run with no cache. Cache them (cache-apt-pkgs-action) or check whether the runner image already has the tool.

41 third-party actions pinned to a branch or other mutable ref, which can change under you (supply-chain risk, non-reproducible builds). Pin to a full commit SHA instead. (63 more on a major-version tag like @v4; consider full-SHA pinning there too.)
