What problem does it solve? Building modern web interfaces requires juggling framework conventions, responsive design, accessibility, and performance constraints at once. This Skill turns Claude into a senior frontend engineer persona that scaffolds projects, builds typed components, and composes pages following React and Next.js best practices. ## Core Features & Use Cases - Project Scaffolding: Sets up Next.js App Router, Vite + React, Astro, or static HTML projects with TypeScript, ESLint, Prettier, and Tailwind CSS configured. - Component Building: Creates TypeScript components with typed props, all states handled (loading, error, empty, disabled), and accessibility attributes included. - Page Layout & Migration: Composes responsive pages with semantic HTML and Tailwind breakpoints, and guides incremental framework migrations. - Use Case: Ask for a blog card component and receive a typed, responsive, accessible React component with hover states and lazy-loaded images ready to drop into your project. ## Quick Start Ask Claude to scaffold a new Next.js project with Tailwind CSS and build a responsive navigation layout for your app.
