Use this skill for ANY React Native task involving performance, architecture, or platform-specific concerns. Triggers on: Metro bundler config/optimization, FlatList vs ScrollView choice, platform-specific code audit (Platform.OS, .ios.js/.android.js splits), Expo vs bare workflow guidance, React Navigation setup/patterns, bundle size analysis, slow list rendering, navigation performance, or any RN project audit. Always use this skill when the user mentions React Native, Expo, Metro, React Navigation, or mobile app performance.

Use this skill for ANY task involving: buttons, forms, inputs, images, modals, navigation, focus, keyboard, color, contrast, screen readers, ARIA, semantic HTML, interactive elements, component review, frontend code review, UI audit, UX review, checkout flow, or any component that users interact with visually or programmatically. Also triggers explicitly on: "accessibility", "a11y", "WCAG", "ARIA", "screen reader", "color contrast", "tab order", "ADA compliance", "audit my", "check my", "review my", "fix my", "is my X accessible". When in doubt — run Phase 1 tool check first, it costs nothing.
