What it does

In the author's own words, from each skill's SKILL.md.

  • nextjs-advanced-routing

    Guide for advanced Next.js App Router patterns including Route Handlers, Parallel Routes, Intercepting Routes, Server Actions, error boundaries, draft mode, and streaming with Suspense. CRITICAL for server actions (action.ts, actions.ts files, 'use server' directive), setting cookies from client components, and form handling. Use when requirements involve server actions, form submissions, cookies…

  • nextjs-anti-patterns

    Identify and fix common Next.js App Router anti-patterns and mistakes. Use when reviewing code for Next.js best practices, debugging performance issues, migrating from Pages Router patterns, or preventing common pitfalls. Activates for code review, performance optimization, or detecting inappropriate useEffect/useState usage. CRITICAL: For browser detection, keep the logic in the user-facing comp…

    nextjs-anti-patterns/SKILL.md on GitHub (opens in a new tab)
  • nextjs-app-router-fundamentals

    Guide for working with Next.js App Router (Next.js 13+). Use when migrating from Pages Router to App Router, creating layouts, implementing routing, handling metadata, or building Next.js 13+ applications. Activates for App Router migration, layout creation, routing patterns, or Next.js 13+ development tasks.

    nextjs-app-router-fundamentals/SKILL.md on GitHub (opens in a new tab)
  • nextjs-client-cookie-pattern

    Pattern for client components calling server actions to set cookies in Next.js. Covers the two-file pattern of a client component with user interaction (onClick, form submission) that calls a server action to modify cookies. Use when building features like authentication, preferences, or session management where client-side triggers need to set/modify server-side cookies.

    nextjs-client-cookie-pattern/SKILL.md on GitHub (opens in a new tab)
  • nextjs-dynamic-routes-params

    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).

    nextjs-dynamic-routes-params/SKILL.md on GitHub (opens in a new tab)
  • nextjs-pathname-id-fetch

    Focused pattern for fetching data using URL parameters in Next.js. Covers creating dynamic routes ([id], [slug]) and accessing route parameters in server components to fetch data from APIs. Use when building pages that display individual items (product pages, blog posts, user profiles) based on a URL parameter. Complements nextjs-dynamic-routes-params with a simplified, common-case pattern.

    nextjs-pathname-id-fetch/SKILL.md on GitHub (opens in a new tab)
  • nextjs-server-client-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…

    nextjs-server-client-components/SKILL.md on GitHub (opens in a new tab)
  • nextjs-server-navigation

    Guide for implementing navigation in Next.js Server Components using Link component and redirect() function. Covers the difference between server and client navigation methods. Use when adding links, redirects, or navigation logic in server components without converting them to client components unnecessarily.

    nextjs-server-navigation/SKILL.md on GitHub (opens in a new tab)
  • nextjs-use-search-params-suspense

    Pattern for using useSearchParams hook with Suspense boundary in Next.js. Covers the required combination of 'use client' directive and Suspense wrapper when accessing URL query parameters in client components. Use when building search interfaces, filters, pagination, or any feature that needs to read/manipulate URL query parameters client-side.

  • vercel-ai-sdk

    Guide for Vercel AI SDK v5 implementation patterns including generateText, streamText, useChat hook, tool calling, embeddings, and MCP integration. Use when implementing AI chat interfaces, streaming responses, tool/function calling, text embeddings, or working with convertToModelMessages and toUIMessageStreamResponse. Activates for AI SDK integration, useChat hook usage, message streaming, or to…

Review before you install

A skill is a set of instructions and scripts your agent will follow, and it can run code on your machine. Read the SKILL.md and any scripts first — this listing is not a security review.
