The big idea
Zod is a tiny library that lets you describe what valid data looks like and reject anything that doesn't match. AI is great at writing Zod schemas because they're pure shape — exactly what AI patterns at well.
Some examples
- Ask AI: 'Write a Zod schema for this JSON API response.'
- AI infers TypeScript types from the schema for free.
- AI shows you how to .safeParse so bad data doesn't crash your app.
- AI uses Zod to validate env vars at startup.
Try it!
Pick an API response in your project and ask AI to write a Zod schema for it. Add .parse() at the boundary.
