Without proper AI configuration, you waste hours on:

AI IDEs are powerful, but they're generic by default. They don't know your stack, your patterns, or your preferences.

Outdated patterns

AI generates Pages Router code with getServerSideProps when you need App Router with Server Components.

Repetitive explanations

You re-explain your Supabase auth pattern, RLS policies, and client setup every single conversation.

Security gaps

Stripe webhook handlers without signature verification. Missing RLS policies. Exposed API keys.

Endless fix loops

TypeScript errors pile up because AI ignores strict mode. You spend more time fixing than building.

What's included

Everything your AI IDE needs to build production-grade SaaS

29 files, tested as an integrated system. Not a random collection of rules — a complete configuration that works together.

7 Cursor Rule Files

Technology-specific .mdc rules

7 Claude Code Commands

Task automation slash commands

Production .cursorrules & CLAUDE.md

Master configuration files

25+ Code Snippets

Supabase queries & Stripe webhooks

Database Schema & Templates

SQL, middleware, webhook handler

4 Documentation Guides

Quickstart, setup, customization

Two AI IDEs. One unified configuration.

Whether you use Cursor, Claude Code, or both — this kit has you covered with consistent, high-quality AI output.

Cursor IDE
Cursor Ready

Drop-in .cursorrules and 7 technology-specific .mdc rule files. Cursor instantly understands your Next.js 15 + Supabase + Stripe architecture.

  • .cursorrules master config
  • Next.js 15 App Router rules
  • Supabase auth & DB rules
  • Stripe payments rules
  • TypeScript strict mode rules
  • Tailwind v4 + shadcn/ui rules
  • Vitest testing rules
Claude Code
Claude Code Ready

Comprehensive CLAUDE.md plus 7 custom slash commands that automate entire workflows — from project setup to deployment.

  • 800+ line CLAUDE.md
  • /setup-project command
  • /add-auth command
  • /add-payments command
  • /add-crud command
  • /add-api-route command
  • /deploy command
Battle-tested
Production Tested

Every rule and command is tested against real SaaS projects. Not theoretical — these configs produce working, secure code.

  • Good & bad code examples
  • Security best practices
  • RLS policy patterns
  • Webhook verification
  • Type-safe patterns
  • Error handling patterns
  • Performance optimized

# CLAUDE.md — AI Dev Config Kit

## Tech Stack
- **Framework**: Next.js 15 (App Router only)
- **Language**: TypeScript 5.x (strict mode)
- **Database**: Supabase (PostgreSQL + RLS)
- **ORM**: Drizzle ORM
- **Auth**: Supabase Auth (@supabase/ssr)
- **Payments**: Stripe (Checkout, Subscriptions)
- **Styling**: Tailwind CSS v4 + shadcn/ui
- **Testing**: Vitest + React Testing Library

## Architecture Rules
- Server Components by default
- "use client" only for interactivity
- Server Actions for all mutations
- Validate ALL inputs with Zod
- Use Result<T> type for error handling

## Anti-patterns (NEVER do these)
- Never use `any` type
- Never use Pages Router (getServerSideProps)
- Never fetch data client-side when SSR works
- Never skip RLS policies
- Never hardcode API keys or secrets
- Never skip Stripe webhook verification
...

The full CLAUDE.md is 821 lines with detailed coding standards, architecture rules, anti-patterns, and 7 custom slash commands.
