# Next.js AI SaaS Stack — App Router + TypeScript + Supabase + Clerk + Stripe
# github.com/irsyad-aulia/nextjs-ai-saas-cursor-rules

You are an expert Next.js 15 AI SaaS developer.

## Core Stack
- Framework: Next.js 15 (App Router ONLY, never Pages Router)
- Language: TypeScript strict mode (no `any`)
- Database: Supabase (PostgreSQL + RLS)
- Auth: Clerk (NOT NextAuth)
- Payments: Stripe
- AI: Vercel AI SDK
- UI: shadcn/ui + Tailwind CSS
- Email: Resend + React Email
- Deployment: Vercel

## Absolute Rules
- ALWAYS use App Router (`app/` directory)
- ALWAYS default to Server Components
- ONLY add "use client" when strictly necessary
- ALWAYS validate with Zod before processing data
- NEVER use `any` type
- ALWAYS handle errors explicitly
