Nuxt Ui

MSW `.ui` single entry point — design + component API + builder + runtime. Anchor/pivot/RectTransform, UIGroup/CanvasGroup hierarchy, layout recipes (HUD/popup/toast/menu/inventory/scroll-list), full API tables for ButtonComponent/TextGUIRendererComponent/SpriteGUIRendererComponent/ScrollLayoutGroup/GridView/TextInput/Slider/Mask/AvatarGUIRenderer + UI enums (AlignmentType/TextOverflowMode/ImageType/FillAmount), `.mlua` runtime patterns (popup open-close, toast, HP bar, GridView, drag, tab, cooldown, world nametag), UI-client-only caveats (nil on server, no RPC), `.ui`↔`.mlua` UUID auto-binding (write+injectBindings), resolution/safe-area/touch. UIBuilder (msw_ui_builder.cjs): all node types (empty/panel/text/sprite/button/slider/scrollLayout/textInput/group/mask/gridView/avatar/skeleton etc.), component add/replace/patch/remove, 13 anchor presets+stretch, auto-inject .mlua UUID bindings after write.

LobeHub React component conventions. Use when editing TSX UI, choosing base-ui vs @lobehub/ui vs antd, styling with antd-style, component boundaries, local state, layouts, render performance, or memoization.

Use when building Next.js 14+ applications with App Router, server components, or server actions. Invoke to configure route handlers, implement middleware, set up API routes, add streaming SSR, write generateMetadata for SEO, scaffold loading.tsx/error.tsx boundaries, or deploy to Vercel. Triggers on: Next.js, Next.js 14, App Router, RSC, use server, Server Components, Server Actions, React Server Components, generateMetadata, loading.tsx, Next.js deployment, Vercel, Next.js performance.

Use when building React 18+ applications in .jsx or .tsx files, Next.js App Router projects, or create-react-app setups. Creates components, implements custom hooks, debugs rendering issues, migrates class components to functional, and implements state management. Invoke for Server Components, Suspense boundaries, useActionState forms, performance optimization, or React 19 features.

MUST activate when the user wants to build, create, or generate a React application, React app, web application, single-page application (SPA), or frontend application — even if no project files exist yet. MUST also activate when the project contains a uiBundles/*/src/ directory or sfdx-project.json and the prompt says create, build, construct, or generate a new app, site, or page from scratch — even if the prompt also describes visual styling. MUST also activate when the task spans more than one ui-bundle skill. Use this skill when building a complete app end-to-end. Do NOT use for Lightning Experience apps with custom objects (use generating-lightning-app). Do NOT use for single-concern edits to an existing page (use building-ui-bundle-frontend).

Refactor high-complexity React components in Dify frontend. Use when `pnpm analyze-component --json` shows complexity > 50 or lineCount > 300, when the user asks for code splitting, hook extraction, or complexity reduction, or when `pnpm analyze-component` warns to refactor before testing; avoid for simple/well-structured components, third-party wrappers, or when the user explicitly wants testing without refactoring.
