Mechanism
Breaks down how the skill works and what it produces, so you can quickly judge whether it fits your scenario and value.
When building or modifying native modules/views for Expo (Swift, Kotlin, TypeScript), adding native functionality, wrapping platform SDKs, or editing module config/plugins.
create-expo-module scaffold; choose local vs standalone, platforms, featuresadd-platform-support for new platformsA correctly structured Expo native module with autolinking-ready config, native bindings, and TypeScript API for React Native consumption.
Use Cases
A developer wants to add camera access to their Expo app. They use the expo-module skill to scaffold a local module with Function/AsyncFunction features via create-expo-module, then replace sample code with real Swift/Kotlin camera calls and export a TypeScript API. This avoids manual native setup errors and yields a maintainable module.
A library author maintains a standalone Expo module and needs Android support added. Using the skill, they run create-expo-module add-platform-support, consult module-config references, and extend expo-module.config.json. The module gains Android bindings without breaking iOS, accelerating cross-platform publishing.
