rn-probe

Claude Code's window into a live React Native app.

A daemon + CLI tool that gives Claude Code structured, text-based introspection into a running RN app — component trees, JS errors, native logs, screenshots, tap events, and more. The same pattern as @vercel/next-browser applied to React Native.

Works with bare React Native and Expo (Expo Go + dev builds).

Install

npm install -g @rn-probe/cli

Or via the Claude Code skill system:

npx skills add rn-probe
