Supabase Schema & Migration Builder

An enterprise-grade AI skill engineered to design production-ready PostgreSQL database schemas, Row Level Security (RLS) policies, sequential SQL migration scripts, and Supabase TypeScript type definitions.

Key Features

• Automated Database Schemas: Generates strict PostgreSQL structures complete with primary keys, foreign key relations, constraints (NOT NULL, UNIQUE), and auto-updating updated_at triggers.
• Granular RLS Policies: Built-in security policies tied directly to auth.uid() for SELECT, INSERT, UPDATE, and DELETE operations.
• Supabase CLI Ready: Exports sequential SQL files compatible with supabase migration new.
• Type-Safe Exports: Provides complete TypeScript type definitions matching the schema for seamless integration into Next.js, React, and Node.js codebases.

When to Use

1. Designing SaaS Databases: Quickly blueprint tables, workspace isolation, and multi-tenant structures.
2. Securing Existing Tables: Auto-generate bulletproof Row Level Security policies to protect user data.
3. Database Migrations: Generate standardized version-controlled SQL migration scripts.
4. TypeScript Sync: Keep frontend database types aligned with backend schemas.

Frequently Asked Questions

Q: Which databases and frameworks are supported?
A: It natively supports PostgreSQL and Supabase, with TypeScript definitions formatted for Next.js, React, Vue, and Node.js applications.

Q: How do I run this agent?
A: Provide plain English requirements (e.g., "Design a database for a multi-tenant SaaS app with users, organizations, and subscription tiers"), and the builder outputs fully formatted SQL and TypeScript code.
