SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

This skill provides a structured, security-conscious framework for developing with the Supabase ecosystem, preventing common pitfalls like insecure RLS policies, BOLA vulnerabilities, and configuration errors.

Core Features & Use Cases

  • Security Auditing: Validates RLS policies, view security, and storage access controls against known Supabase security traps.
  • Database Management: Guides schema migrations, table exposure to the Data API, and the use of Postgres extensions like pg_vector.
  • Use Case: When building a multi-tenant application, use this skill to ensure your RLS policies correctly implement row-level isolation and that your database functions are configured with the correct security invoker settings.

Quick Start

Use the supabase skill to audit the current RLS policies in the public schema for potential security vulnerabilities.

FAQPage Schema
How do I audit Supabase RLS policies for security vulnerabilities?

To audit Supabase RLS policies, validate row-level security policies, view security, and storage access controls against known Supabase security traps like BOLA vulnerabilities. This structured security framework prevents insecure policy configurations and ensures correct row-level isolation for multi-tenant applications.

How do I manage database schema migrations in a Supabase project?

Manage Supabase database schema migrations by following structured guidance for schema changes, exposing database tables to the Data API, and configuring Postgres extensions like pg_vector. This framework ensures version-specific documentation adherence and established security best practices.

What is the best way to implement multi-tenant row-level isolation in Supabase?

The best way to implement multi-tenant row-level isolation in Supabase is by designing RLS policies that correctly enforce row-level isolation and configuring database functions with the correct security invoker settings to prevent unauthorized data access across tenants.

Does this Supabase development guidance cover CLI operations and API integration?

Yes, this Supabase development guidance covers CLI operations and API integration, providing comprehensive instructions for managing Supabase projects using the supabase-js library while adhering to established Postgres security best practices and version-specific documentation.

Why are my Supabase database functions vulnerable to BOLA attacks?

Supabase database functions are vulnerable to BOLA attacks when they are not configured with the correct security invoker settings. This framework helps identify and resolve these configuration errors by validating function security against known Supabase security traps.

When do I need to use Postgres extensions like pg_vector with Supabase?

You need to use Postgres extensions like pg_vector with Supabase when your application requires vector similarity search capabilities. This framework guides the integration of pg_vector and other extensions while maintaining secure Data API exposure and schema migration management.
