Skill UI

A comprehensive style guide and implementation reference for the Retro Futurism aesthetic. Perfect for designing interfaces that evoke the 1950s and 1960s space age, atompunk, or mid-century modern vibes. It outlines core principles, color palettes, typography, and provides cross-platform code examples (CSS, SwiftUI, Flutter, React Native) to achieve sleek, aerodynamic, chrome finishes.

A comprehensive style guide for implementing the Synthwave and Outrun aesthetic across web and mobile applications. This guide details the core principles, including dark mode backgrounds, glowing neon accents (magenta, cyan), and the signature perspective grid. It provides technical examples using CSS, SwiftUI, Flutter, and React Native to achieve authentic retro-futuristic visual fidelity.

A comprehensive guide for implementing Typography First Design across web and mobile applications. This style emphasizes using type as the primary visual element, minimizing decorative UI elements (chroming) to create a highly focused, high-impact, and sophisticated user experience. Includes specific implementation details for CSS, SwiftUI, Flutter, and React Native.

This skill provides expert guidance on design engineering, focusing on UI polish, micro-interactions, and high-craft component decisions. It is ideal for reviewing frontend code (React, CSS, Tailwind) to elevate perceived quality, addressing details like easing, duration, and physical feedback. Use it when subtle detail and refined taste are critical differentiators.

This comprehensive skill provides a holistic approach to building modern, accessible, and visually stunning user interfaces. It combines the highly accessible components of shadcn/ui (built on Radix UI), the utility-first power of Tailwind CSS, and sophisticated visual design principles (Canvas). Use this when developing complex React applications, implementing full design systems, ensuring responsive layouts across devices, and requiring professional-grade visual compositions, from dashboards to marketing posters. It guarantees consistency, accessibility, and rapid prototyping.

This skill provides comprehensive best practices for designing modern and robust React user interfaces. It covers critical patterns for managing asynchronous data, including optimal loading state indicators (skeletons vs. spinners), structured error handling hierarchies, and designing contextual empty states. Essential for improving user experience during data fetching and operations.

Provides comprehensive guidelines and utilities for modern unit testing using Jest and React Native. Covers Test-Driven Development (TDD) workflows, Behavior-Driven Development (BDD) principles, advanced mocking strategies for modules and GraphQL hooks, and implementing reusable factory functions for props and data. Use this skill to write robust, maintainable, and highly structured unit tests.

This guide details how to integrate Expo and React Native into existing native iOS or Android applications (brownfield development). It addresses the core challenge of adopting new technology incrementally, outlining two distinct approaches: Isolated (consuming prebuilt AAR/XCFramework) and Integrated (adding sources directly to existing build systems like Gradle/CocoaPods).

A comprehensive guide for developers on creating and writing native modules and views using the Expo Modules API. It covers platform-specific implementation details for Swift (iOS), Kotlin (Android), and TypeScript. Use this when integrating system APIs, wrapping platform SDKs, or building complex native functionality that goes beyond standard React Native components.

Use @expo/ui to build high-fidelity, native user interfaces across iOS and Android from a single React codebase. This library renders real native UI components, such as SwiftUI on iOS and Jetpack Compose on Android. It promotes a universal component layer for cross-platform consistency, while also providing controlled access to platform-specific optimizations and drop-in replacements for existing community libraries.

This comprehensive skill demonstrates advanced usage patterns for Formik, a popular React form handling library. It covers basic form setup, complex validation schema creation using Yup (including conditional logic), field helper utilities, and integrating form submissions with GraphQL mutations for both creation and editing scenarios.

This skill defines a framework-agnostic, scalable architecture pattern for React and React Native applications. It mandates feature modules, strict state separation (server vs. UI), and disciplined import rules to create predictable, maintainable, and highly scalable codebases, regardless of the chosen framework (Next.js, Remix, etc.).
