SKILL.md

Accept className, merge defaults, and optionally use a class-variance helper.

Use remapProps (multiple style props) or cssInterop (map a class prop to a style prop).

On Expo Router, do not add your own SafeAreaProvider (Router already does). Use p-safe, pt-safe, etc.

Sets up and uses NativeWind v4 (Tailwind CSS v3) in Expo React Native apps, including Expo Router. Configures tailwind.config.js, global.css, babel.config.js (jsxImportSource + nativewind/babel), metro.config.js (withNativeWind + input), and app.json (web bundler metro). Troubleshoots “className not applying”, Tailwind CLI compilation, and Metro cache issues. Implements reusable components/variants, dark mode + theming via CSS variables (vars/useColorScheme), and third-party component styling (remapProps/cssInterop). Use when working on Expo projects using NativeWind v4, Tailwind-style className utilities, or when debugging NativeWind configuration. Source: tristanmanchester/agent-skills.
