Supabase Fullstack

Complete Supabase knowledge covering frontend, backend, CLI operations, and security. Merged from the official Supabase agent skill (frontend focus) and production backend patterns from Azdal, CarSah, and Hermex Android.

When to Use

ANY task involving Supabase — Database, Auth, Edge Functions, Realtime, Storage, Vectors, Cron, Queues, client libraries (supabase-js, @supabase/ssr, supabase-py), Flutter integration, CLI operations, MCP server, schema changes, migrations, RLS, security audits.

Part 1: Frontend (Official Supabase)

Core Principles

1. Supabase changes frequently — verify against changelog before implementing. Fetch https://supabase.com/changelog.md, scan for breaking-change tags, follow linked pages. Then look up the relevant topic using MCP search_docs or append .md to any docs URL.

2. Verify your work. After any fix, run a test query. A fix without verification is incomplete.
