Guide for Next.js App Router dynamic routes and pathname parameters. Use when building pages that depend on URL segments (IDs, slugs, nested paths), accessing the `params` prop, or fetching resources by identifier. Helps avoid over-nesting by defaulting to the simplest route structure (e.g., `app/[id]` instead of `app/products/[id]` unless the URL calls for it).
Design and build reusable, maintainable UI components following modern architecture patterns for React, Vue, or other frameworks. Use this skill when creating component files (.jsx, .tsx, .vue), implementing component logic, managing component state, defining props interfaces, or organizing component hierarchies in directories like components/, views/, or pages/. Apply this skill when building functional components with hooks (React), composition API components (Vue), single-file components, implementing component composition patterns, managing local vs. lifted state, or creating custom hooks for shared logic. This skill ensures components follow single responsibility principle, are properly encapsulated, have clear prop interfaces with TypeScript types, support reusability across contexts, and follow modern patterns like atomic design, container/presentational separation, and compound components.

Guide for choosing between Server Components and Client Components in Next.js App Router. CRITICAL for useSearchParams (requires Suspense + 'use client'), navigation (Link, redirect, useRouter), cookies/headers access, and 'use client' directive. Activates when prompt mentions useSearchParams, Suspense, navigation, routing, Link component, redirect, pathname, searchParams, cookies, headers, async components, or 'use client'. Essential for avoiding mixing server/client APIs.
