29 .mdc architecture rules that prevent AI coding assistants from hallucinating insecure auth, deprecated imports, and broken Next.js 15 patterns. Built for Cursor Agent and Claude Code.

⚡ Vibe Stack

Stop fixing AI-generated bugs. Start shipping production apps.

A Next.js 15 + Supabase boilerplate with 29 .mdc architecture rules that physically prevent AI coding assistants from hallucinating insecure auth, deprecated packages, and broken patterns.

The problem: AI models generate code that compiles perfectly but ships critical vulnerabilities — getSession() instead of getUser(), synchronous params that crash in Next.js 15, missing RLS policies that expose your database. These bugs are invisible until production.

The fix: Architecture rules that override the AI's training data. When a rule says "NEVER use getSession()", the model is constrained to generate the secure pattern. Every time.

🚀 Quick Start

git clone https://github.com/vibestackdev/vibe-stack.git
cd vibe-stack
npm install
cp .env.example .env.local
# Add your Supabase URL + anon key to .env.local
npm run dev

Open in Cursor and start building. The rules activate automatically — zero configuration.

🆓 What's Free (This Repo)

This open-source repo includes 5 foundational architecture rules — the most critical safeguards for any Next.js 15 + Supabase project:

Free Rule	What It Prevents
`supabase-auth-security.mdc`	Bans `getSession()`, enforces `getUser()` for JWT verification
`nextjs15-params.mdc`	Prevents synchronous `params` access (the #1 Next.js 15 breaking change)
`supabase-ssr-only.mdc`	Blocks deprec
