SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

This Skill helps you correctly implement, troubleshoot, and safely iterate on Supabase features—especially around auth, RLS, Data API exposure, and schema changes—so you don’t introduce breaking changes or security gaps.

Core Features & Use Cases

  • Supabase-change-proof implementation guidance: Verifies breaking changes via the Supabase changelog before making implementation decisions.
  • Security-first troubleshooting: Provides an RLS, JWT claim safety, view security, and storage access checklist to prevent common Supabase pitfalls.
  • Safe schema iteration to production-ready migrations: Recommends using direct SQL iteration paths and a disciplined migration creation workflow when ready.

Quick Start

Use the supabase skill when you need to debug an RLS or Data API access issue for a table after a migration, then validate the fix with a test query and confirm role grants and RLS policies.

FAQPage Schema
How do I safely apply Supabase schema migrations without breaking RLS policies?

To apply Supabase schema migrations safely, iterate using direct SQL paths and follow a disciplined migration workflow. Always verify breaking changes via the Supabase changelog, then run test queries to confirm RLS policies remain intact.

Why does my Supabase Data API expose restricted table data after a migration?

Your Supabase Data API exposes restricted data when explicit table grants are misconfigured or RLS is disabled. Apply explicit Data API grants, ensure RLS is enabled on the table, and validate access by running a test query.

What is the best way to secure Supabase storage access control in a Next.js project?

The best way to secure Supabase storage access control is to use documented secure patterns for storage upserts and JWT session handling. Enforce strict RLS policies on storage buckets to prevent unauthorized access in your Next.js SSR integration.

Can I use the Supabase CLI to troubleshoot auth and JWT claim safety issues?

Yes, you can use the Supabase CLI to troubleshoot auth and JWT claim safety issues. Follow a security-first checklist to validate JWT claims, verify view security, and ensure your client or SSR integration handles sessions correctly.

When do I need to check the Supabase changelog before implementing database changes?

You need to check the Supabase changelog before any database, auth, or API schema iteration to prevent breaking changes. Verifying changelog updates ensures your RLS configurations and Data API exposure remain secure during production-ready migrations.

Does Supabase Row Level Security work with views and client-side data fetching?

Supabase Row Level Security works with views and client-side data fetching if you apply documented secure patterns for view security. Ensure explicit grants are set and validate your RLS policies by running test queries after changes.
