Supabase Backend Platform

This gives Claude working knowledge of Supabase's core APIs: Postgres queries through PostgREST, built-in auth with OAuth and magic links, file storage, and realtime subscriptions. The skill covers practical patterns like Row Level Security policies, database function calls via RPC, and client initialization for Next.js or React apps. It's most useful when you're building a full-stack app and want Claude to help wire up backend services without writing everything from scratch. The examples are concrete enough that Claude can generate actual working code for common tasks like filtered queries, user signup flows, and permission policies. Saves you from context-switching to docs when prototyping or adding features that touch the database layer.
