React Native and Expo best practices for performant mobile apps across list rendering, animations, navigation, and native modules. \n \n Covers eight rule categories prioritized by impact: list performance (FlashList, memoization, callback stability), animations (GPU properties, derived values), navigation, UI patterns, state management, rendering, monorepo structure, and configuration \n List performance rules address critical concerns like virtualizing large lists, optimizing images, and avoid

Diagnose requirements problems and guide discovery of real needs instead of premature solutions. \n \n Identifies five distinct requirements states (no problem statement, solution-first thinking, vague needs, hidden constraints, scope creep) with specific symptoms, key questions, and interventions for each \n Helps distinguish stated wants from underlying problems through problem archaeology, Jobs-to-be-Done interviews, and constraint inventory exercises \n Produces persistent artifacts (Problem

Build terminal user interfaces with three framework options: imperative core API, React reconciler, or Solid reconciler. \n \n Three frameworks to choose from: core (maximum control), React (familiar component patterns), or Solid (fine-grained reactivity) \n Comprehensive component library covering text display, containers, inputs, code/diff viewers, layout, keyboard handling, animations, and testing \n Critical rules include using create-tui for new projects, avoiding process.exit() , and nesti

Create effective visual communication through research-backed design principles.

Material Design 3 and Jetpack Compose patterns for building modern, adaptive Android applications. \n \n Covers Material Design 3 components (cards, buttons, navigation, text fields, dialogs) with dynamic color theming and tonal palettes for accessibility \n Provides Jetpack Compose layout patterns including Column/Row, LazyColumn/LazyVerticalGrid, and adaptive layouts for phones, tablets, and foldables \n Includes navigation implementations for bottom navigation, navigation drawers, and Navigat

Transform into a React + Vite expert with deep knowledge of modern React development patterns, optimal project organization, performance optimization techniques, and production-ready configurations. This skill provides everything needed to build fast, maintainable, and scalable React applications using Vite as the build tool.

Cross-platform mobile apps with React Native and Expo, including navigation, native modules, and performance optimization. \n \n Covers setup, component structure, platform-specific code (iOS/Android), and testing workflows with error recovery for Metro bundler, build failures, and native module issues \n Implements navigation hierarchies (tabs, stacks, drawers) via Expo Router or React Navigation with deep linking and back-button handling \n Optimizes list rendering with FlatList, memo, and use

Implement purposeful, performant animations that enhance UX without overwhelming users. Focus on key moments: hero intros, hover feedback, content reveals, and navigation transitions.

Master Flutter's constraint system to build responsive, overflow-free layouts efficiently. \n \n Core principle: constraints flow down, sizes flow up, parents set position. Never pass unbounded constraints in flex boxes or scrollable regions. \n Use Row / Column for linear layouts, Expanded / Flexible for space distribution, Stack for overlapping elements, and SizedBox for tight constraints. \n Apply LayoutBuilder for responsive sizing or conditional rendering for adaptive layouts across mobile,
