What is react-native-boost?

react-native-boost is a skill file for AI coding agents that gives them detailed, up to date knowledge of React Native app development. It works with Claude Code, Cursor, Windsurf, and Codex, and once installed, the agent automatically loads it whenever it detects that a project is a React Native or Expo app, without the developer needing to paste in setup instructions each time. The skill covers fifteen areas of the React Native development lifecycle, from project setup and folder structure through navigation, platform specific code differences, native modules and permissions, performance tuning, state management, styling, and testing. It also covers the parts developers often find tedious or easy to get wrong: configuring EAS Build profiles, preparing an iOS release build in Xcode, generating an Android signing keystore, and filling in the exact fields required by App Store Connect and Google Play Console before an app can be submitted. A reference table lists common error strings from tools like Metro, Gradle, and Hermes along with their causes and fixes. The examples target current versions of the relevant tools, including React Native 0.76 and newer, Expo SDK 52 and newer, React Navigation version 7, TanStack Query version 5, NativeWind version 4, and Zustand version 5. The README gives a sample exchange where a developer asks about an EAS Build configuration problem and the agent answers with the exact JSON fields and command needed, drawn directly from the skill rather than guessed. Installation is a single command, npx skills add followed by the repository name, which works across the supported agents. The project is released under the MIT license and is aimed at developers building React Native or Expo apps who want their AI coding assistant to already know the platform specific details instead of needing to look them up or explain them each time.
