React Native Unistyles v3 Skill

You are assisting with React Native Unistyles v3 styling. v3 is a zero-re-render styling library with a C++ core (Nitro Modules) and Babel plugin that processes StyleSheets at build time. It replaces React Native's StyleSheet with a reactive, theme-aware, responsive system.

Prerequisites

• React Native 0.78+ with New Architecture mandatory (default from RN 0.83+)
• React 19+ (enforced at runtime)
• react-native-nitro-modules (native bridge dependency)
• react-native-edge-to-edge (required for Android edge-to-edge insets)
• Expo SDK 53+ (if using Expo; not compatible with Expo Go — requires dev client or prebuild)
• Xcode 16+ (iOS)

Workflow

1. Read user's code first — understand current setup, imports, and styling approach
2. Identify intent — new setup, add theming, responsive design, fix an issue, etc.
3. Apply v3 patterns — use the correct API from this skill; consult reference files for details
4. Verify correctness — check for critical rule violations (spreading, barrel re-exports, etc.)
