Skill UI

A comprehensive reference guide detailing best practices, rules, and optimizations for building high-performance React Native and Expo applications. It covers critical areas such as list virtualization, complex animations, UI patterns, state management, and monorepo structure, helping developers avoid common pitfalls and maximize app speed and stability.

A comprehensive guide for implementing view transitions in React and Next.js. Learn how to animate UI states, shared element animations, and route changes using the native ViewTransition API. Covers best practices for maintaining spatial continuity and adapting to different navigation contexts.

This skill automates the migration of existing frontend code (including React, Vue, Angular, and Next.js components) into a structured Stitch Design. It orchestrates the extraction of a self-contained HTML file, analyzes the source code to build a comprehensive design system document, and finally uploads both assets into your Stitch project for iteration and improvement.

Analyzes any frontend codebase (React, Vue, Svelte, Angular, plain CSS, Tailwind) to document the complete design system. It extracts crucial visual elements—including color palettes, typography, spacing scales, and component patterns—directly from source files, without needing to build, render, or run the application. Ideal for design audits, visual language documentation, or migrating a project's identity into a design tool.

This skill captures a fully self-contained static HTML snapshot from any running web application (e.g., React, Vue, Next.js). Using Puppeteer, it renders the live DOM, automatically inlining all CSS styles and converting images, assets, and backgrounds to base64 data URIs. This ensures the generated HTML file is completely self-sufficient and requires no external network connection, making it perfect for sharing UI states, creating documentation, or preparing assets for offline viewing.

This skill acts as a mobile engineering bridge, converting web designs provided by Stitch into high-quality, production-ready React Native components. It handles complex tasks including translating HTML/CSS layouts into React Native primitives, extracting design tokens (colors, spacing) into a central theme file, and ensuring adherence to native component architectural rules. Ideal for developers integrating web-based prototypes into mobile applications.

A comprehensive guide covering production-grade Android and cross-platform app development. It details best practices for selecting technology stacks (Kotlin, Flutter, React Native, KMM) and implementing modern architectures like Clean Architecture and MVI/MVVM across various platforms.

This guide helps developers audit and clean up Vite + React projects initialized using the Lovable scaffolding tool. It systematically removes all boilerplate artifacts, including placeholder assets, dedicated dependencies (like lovable-tagger), generated documentation, and unnecessary components (e.g., unused Radix deps). The goal is to deliver a clean, fully owned, and production-ready codebase.

This skill generates a complete React component structure following the industry-standard Container/Presentation pattern. It automatically scaffolds necessary files, including TypeScript, Storybook, and SCSS styles, ensuring adherence to project conventions. Use this when building new, scalable components, allowing you to properly classify whether the component is UI-focused (Presentation) or logic-heavy (Container).

This comprehensive skill serves as an entry point for all web UI design needs, covering components, pages, dashboards, and advanced layouts using React, Vue, or pure HTML/CSS. It addresses not only aesthetics and polish (color, typography, spacing) but also deep structural concerns like responsive design, UX auditing, and visual system implementation. Use it whenever a user asks to improve the look, feel, or function of a digital interface.

This skill transforms scattered competitive updates (features, pricing, hiring, partnerships) into structured strategic intelligence. It assesses the threat level, determines whether a move is reactive or proactive, and provides concrete implications and actionable recommended responses directly tied to your product roadmap and business strategy.

A comprehensive guide for implementing Brutalist Typography aesthetics across web and mobile platforms. This style intentionally breaks traditional design rules, utilizing massive system fonts, clashing colors (Black, White, Red), and aggressive layouts (overlapping, negative margins) to create a raw, attention-demanding, and unapologetic visual experience. Includes detailed CSS, SwiftUI, Flutter, and React Native examples.
