What problem does it solve? Working with Supabase involves frequent API changes, subtle RLS security traps, and CLI version differences that cause silent failures and vulnerabilities. This Skill provides up-to-date guidance for building, securing, and debugging Supabase projects without relying on outdated training data. ## Core Features & Use Cases - Security Checklist: Covers Supabase-specific traps like user_metadata in JWTs, views bypassing RLS, SECURITY DEFINER functions, and BOLA/IDOR policy patterns. - Schema Management: Supports both declarative schemas and imperative migrations, with advisor checks and clean migration generation via the CLI or MCP server. - Debugging Workflows: Directs agents to fetch current monitoring and debugging docs before diagnosing REST API, Postgres, Auth, Realtime, Edge Function, or Storage errors. - Use Case: When a user reports that a newly created table is inaccessible via the REST API, the Skill guides checking Data API settings, granting role access, and enabling RLS correctly. ## Quick Start Ask the agent to help you create a Supabase table with secure RLS policies and generate a migration for it.
