What you will learn
- Dependency caching and concurrency groups cut CI time.
- Matrices test several versions in parallel.
- Minimal permissions and pinned actions reduce supply-chain risk.
CI is a product your team uses daily
Slow CI changes behaviour: people batch changes, skip tests locally and merge riskier code. Insecure CI is worse, because workflows hold tokens that can push code and publish packages.
A good workflow is fast by default and grants only the permissions each job needs.
