Recap and Practice
Key takeaways
- Guardrails are what let the AI sprint while a safety net catches the falls — they speed you up, not down.
- Tests, type checking, and linting catch mistakes for free; wire them into so the checks run automatically.
- Scope AI changes narrowly and read every diff critically before you merge.
- A red check is information — triage it (real bug / outdated test / flaky check) before letting AI "fix" it.
- Never ship a change you didn't read.
Try it
In a project of yours, set up one automated check you don't have yet — a single test, a linter, or a type-check step — and add it to a CI workflow so it runs on every push. Then deliberately break something small and confirm the check goes red before you fix it.
Add a CI workflow to this repo that runs the test suite, the linter,
and the type checker on every push and pull request. Generate the
config, explain each step, and tell me how to read the output when a
check fails so I can tell a real bug from an out-of-date test.
