What problem does it solve? Supabase features, CLI commands, and API conventions change frequently, and common mistakes like misconfigured RLS policies, exposed service keys, or broken migrations silently create security holes and failed deployments. This Skill provides verified, security-first guidance for any Supabase task. ## Core Features & Use Cases - Security-First Checklists: Enforces RLS on exposed schemas, prevents user_metadata authorization traps, and flags view/storage access pitfalls before they ship. - CLI and MCP Workflows: Discovers correct Supabase CLI commands via --help, troubleshoots MCP server connections, and handles version-specific gotchas like db query requiring CLI v2.79.0+. - Safe Schema Migrations: Iterates on schema changes with execute_sql, runs advisors, then commits clean migrations via supabase db pull without polluting migration history. - Use Case: When adding a new table with row-level security in a Next.js app, the Skill verifies current docs, writes correct RLS policies, runs security advisors, and generates a clean migration file. ## Quick Start Ask the agent to help you add a new table with RLS policies to your Supabase project and generate the migration file.
