Guardrails, Tests & Reviews

Vibe coding lets you move fast. The danger is that you also move fast in the wrong direction — and because the AI sounds confident, you might not notice until something breaks in front of a real user. Guardrails are how you keep the speed without the crashes.

This chapter is not about turning your project into a bureaucracy. It's about a handful of cheap, automatic checks that catch the AI's mistakes (and yours) before they reach production. Set them up once, and they work in the background forever. The whole philosophy of this chapter is one line: never ship something you don't understand. Guardrails are what make "understand it" cheap enough that you'll actually do it every time.
