Production-ready React Native screen creator that implements screens following established project patterns, enforcing best practices (NO mock data, real Supabase queries, BaseScreen wrapper, safe navigation, analytics tracking). Use when user says "create screen", "implement screen", "build [ScreenName]", or after analyzing existing screen. ALWAYS reads PROJECT_MEMORY.md, applies ACCEPTANCE_CHECKLIST.md, and avoids known errors.
Implement mobile-first responsive design patterns for all screen sizes. Use when building layouts that need to work across desktop, tablet, and mobile devices.
Automates creation of MobX State Tree stores following Fitness Tracker App patterns for domain models, collections, and root store integration. Use when creating new MST stores, models, or extending existing store functionality with proper TypeScript typing, actions, views, and integration patterns.
Create UI components for SwiftUI. Use when creating buttons, cards, input fields, modals, bottom sheets, loading views, empty states, creating components from design images, coding UI from Figma, making custom views, creating reusable views.
React component development patterns for building UI components with hooks, state management, error handling, loading states. Use when creating React components, managing component state, handling user interactions, or working with component lifecycle.
Design and build reusable, composable UI components following single responsibility principle with clear interfaces and proper state management. Use this skill when creating new React components, Vue components, Angular components, or any UI component files, refactoring existing components for reusability, implementing component props or interfaces, managing component state (useState, data properties), building component composition patterns, creating custom hooks or composables, implementing component lifecycle methods, documenting component APIs, splitting large components into smaller ones, or working with component files (.jsx, .tsx, .vue, .svelte, .component.ts). Use when working with component directories like components/, views/, pages/, or widgets/ in any frontend framework.
Patterns for building React components with Radix UI, TailwindCSS, react-hook-form, and Framer Motion
This skill should be used when the user asks to "create a React component", "use React hooks", "handle state", "implement forms", "use useOptimistic", "use useActionState", "create Server Components", "add interactivity", or discusses React patterns, component architecture, or state management. Always use the latest React version and modern patterns.
Designs modern, clean iOS screens and components for Expo React Native apps following Apple HIG with safe areas, Dynamic Type, dark mode, accessibility, Liquid Glass materials, and App Store readiness.
Enforce mobile-first design with compact elements, smaller fonts, and responsive layouts optimized for mobile screens. Use when working on UI, mobile views, responsive design, or when user mentions mobile, UI, layout, or design.
Flutter 3.27/React Native 0.76 with state management and native integration.
Expert knowledge of Vuer UIKit, a React component library for building interactive 3D and UI applications with 38 components and a powerful Dial system
Expo/React Native project conventions and patterns. Use when: building cross-platform mobile apps with Expo, React Native screens, mobile-specific logic. Do not use for: UX decisions (use ux-design), token/component design (use design-system), web-only features. Workflow: ux-design → design-system → this skill (mobile integration).
Comprehensive Framer Motion animation library for React. Covers motion components, variants, gestures, page transitions, and scroll animations. Use when adding animations to React/Next.js applications.
Building shadcn/ui components with Radix UI primitives, CVA variants, accessibility, and MobX integration

Expert in React Native (New Architecture), TurboModules, Fabric, and Expo. Specializes in native module development and performance optimization.
Mobile-first responsive patterns with sticky headers, floating CTAs, accessible navigation, and touch-friendly interactions. Use when implementing responsive layouts, mobile navigation, or ensuring touch-friendly UI.
React Native accessibility patterns for iOS and Android. Use when implementing a11y features.
Apply consistent React Native + Expo conventions for project structure, Expo Router navigation, theming primitives, icons, sqlite data patterns, safe area handling, and bun/bunx tooling. Use when adding or updating screens, components, navigation, data, or dependencies in Expo/React Native apps so work matches these practices.
