Why it exists

InstantDB is realtime, local-first and excellent — but scaffolding a working app (schema + auth + UI + subscriptions) is still 200+ lines of boilerplate every time. This skill takes a natural-language prompt and produces a complete React, vanilla JS or Expo app with InstantDB wired up end-to-end: schema declared, magic-link auth working, queries reactive.

In practice

Scaffold an app

Input

build a multi-user todo with reactions

Output

Complete React app: InstantDB schema (todos, users, reactions), magic-link auth, realtime subscriptions, reaction picker UI.
