What's Inside

Real rules, real impact

.cursorrules

          ## React Patterns

          - Use Server Components by default

          - Add 'use client' only when you need interactivity

          - Before writing a useEffect, ask: can this be

            computed during render or handled by an event handler?

          ## Anti-Patterns Blocked

          ✗ Never use any — use unknown and narrow

          ✗ Don't fetch in useEffect for initial data

          ✗ Don't put secrets in client code

          ## When Generating Code

          - Always include TypeScript types

          - Include error handling and loading states

          - Validate all external input with Zod
