Full-Stack Integration Skill

This Skill defines how frontend and backend talk to each other.

Core Architecture

Frontend (Next.js 16) → Better Auth → JWT → FastAPI → SQLModel → Neon PostgreSQL

Non-Negotiable Rules

1. •Frontend never stores JWT manually
2. •Backend trusts JWT only after verification
3. •Every request is user-scoped
4. •CORS is explicit and locked down

See:

• •auth-flow.md
• •api-client.md
• •cors-and-deployment.md
• •error-handling.md

Context7 Usage

Use Context7 when:

• •Verifying Better Auth token format
• •FastAPI dependency injection edge cases
• •Vercel deployment behavior

Good queries:

• •“FastAPI JWT dependency async example”
• •“Better Auth JWT verification server side”
