SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) and assets (resource) components.

What problem does it solve?

This Skill addresses the complexity of managing Supabase projects, helping developers navigate frequent API changes, security pitfalls, and database schema management without relying on outdated training data.

Core Features & Use Cases

  • Security Auditing: Provides a comprehensive checklist to prevent common vulnerabilities like BOLA, RLS misconfigurations, and insecure API key exposure.
  • Schema Management: Guides users through declarative schema workflows and imperative migration best practices to ensure database integrity.
  • Use Case: When implementing a new user authentication flow, use this Skill to verify that your RLS policies correctly combine role-based access with ownership predicates to prevent unauthorized data access.

Quick Start

Use the supabase skill to audit the current database schema and RLS policies for potential security vulnerabilities.

FAQPage Schema
How do I implement secure RLS policies in Supabase to prevent unauthorized data access?

To implement secure RLS policies in Supabase, combine role-based access control with ownership predicates to prevent unauthorized data access. This approach ensures users can only interact with rows they are explicitly permitted to access.

What is the best way to manage database schema migrations in a Supabase project?

The best way to manage database schema migrations in Supabase is using declarative schema workflows alongside imperative migration best practices. This ensures database integrity throughout the development lifecycle.

How do I audit my Supabase project for common API security vulnerabilities?

Audit your Supabase project for security vulnerabilities by running a comprehensive checklist to detect BOLA, RLS misconfigurations, and insecure API key exposure. This prevents common security pitfalls in production.

Does Supabase SSR support current authentication flows and API integration best practices?

Supabase SSR supports current authentication flows and API integration by adhering to up-to-date documentation for Supabase-js and Postgres extensions. This ensures your implementation avoids outdated training data.

Why do I need local CLI workflows for Supabase development before pushing to production?

You need local CLI workflows for Supabase development to safely test database schema management and authentication flows before production deployment. This full lifecycle approach catches security issues early.
