Frontend Design Review

Generate correct shadcn/Tailwind layouts by applying CSS mental models. This skill should be used when the user asks to 'create a shadcn layout', 'fix layout issues', 'debug CSS height problems', 'make scrolling work', or has issues with Tailwind flex/grid. Keywords: shadcn, Tailwind, layout, CSS, flex, grid, height, scroll, overflow.

Scaffolds a production-ready Next.js turborepo end to end. Runs create-next-app with TypeScript 7, Tailwind CSS, React Compiler, and Cache Components, sets up shadcn/ui with Blode UI components from the Blode registry, blode-icons-react icons, Agentation, and Ultracite (Oxlint, Oxfmt, Lefthook), converts the app into a turborepo, then creates the GitHub repo and deploys to Vercel with a pre-launch checklist. Use when creating a brand-new Next.js app, bootstrapping a turborepo, scaffolding a web project, starting a new repo for a website or marketing site, or asking "create a Next.js project", "set up a turborepo", or "start a new web app". For a TypeScript CLI or npm package, use scaffold-cli. For folder structure and module contracts in an existing app, use codebase-architecture. For building a page inside an existing app, visual direction, palettes, and theming, use ui-design.

Tailwind CSS responsive design and dark mode patterns (2025-2026). PROACTIVELY activate for: (1) dark mode setup (class-based vs media-query, dark: variant), (2) toggling dark mode at runtime (data-theme, html.dark), (3) prefers-color-scheme handling, (4) per-component dark variants, (5) responsive design with dark mode (combining sm:dark:bg-*), (6) system / light / dark / high-contrast theming, (7) CSS color-scheme property, (8) avoiding flash of unstyled content (FOUC) in dark mode, (9) dark-mode color tokens via @theme. Provides: dark-mode toggle implementation, FOUC prevention pattern, color-token templates, and system-preference detection.

Next.js 16 App Router performance, caching, server components, server actions, routing, and codebase-hygiene best practices — plus a category-major review/refactor algorithm with codebase-level (remove/dedup/reuse) findings. This skill should be used when writing Next.js 16 App Router code, configuring caching with 'use cache', building Server Components, setting up parallel/intercepting routes, configuring next.config.js OR proxy.ts, OR auditing/refactoring a Next.js codebase (single file or whole repo). This skill does NOT cover generic React 19 patterns (use react skill) or non-Next.js server rendering.
