Look up Next.js documentation for a topic. Use before implementing any Next.js feature to get accurate, up-to-date framework knowledge.
Next.js 16 proxy convention (replacing middleware). Use when creating middleware, handling URL rewrites, or when the user mentions proxy.ts, middleware.ts, or route interception in Next.js 16+.
Comprehensive coding standards, verification protocols, and templates for Next.js App Router projects. Auto-loads on Next.js detection.
Sets up TraceKit APM in Next.js applications with multi-runtime support, error boundaries, and distributed tracing. Covers both App Router and Pages Router architectures.
This skill should be used when the user asks to "create a Supabase table", "write RLS policies", "set up Supabase Auth", "create Edge Functions", "configure Storage buckets", "use Supabase with Next.js", "migrate API keys", "implement row-level security", "create database functions", "set up SSR auth", or mentions 'Supabase', 'RLS', 'Edge Function', 'Storage bucket', 'anon key', 'service role', 'publishable key', 'secret key'. Automatically triggers when user mentions 'database', 'table', 'SQL', 'migration', 'policy'.
Expert in the Vercel AI SDK. Covers Core API (generateText, streamText), UI hooks (useChat, useCompletion), tool calling, and streaming UI components with React and Next.js.
Expert in Zod — TypeScript-first schema validation. Covers parsing, custom errors, refinements, type inference, and integration with React Hook Form, Next.js, and tRPC.
This skill should be used when the user asks to "write a Next.js app", "follow React best practices", "optimize a Next.js application", "build with the App Router", or needs guidance on modern React and Next.js patterns for 2025.
Sets up Neon Auth in Next.js App Router applications. Configures API routes, middleware, server components, and UI. Use when adding auth-only to Next.js apps (no database needed).
How to write end-to-end tests using createRouterAct and LinkAccordion. Use when writing or modifying tests that need to control the timing of internal Next.js requests (like prefetches) or assert on their responses. Covers the act API, fixture patterns, prefetch control via LinkAccordion, fake clocks, and avoiding flaky testing patterns.
Build and extend Git City — a 3D pixel art city where GitHub profiles become interactive buildings using Next.js, Three.js, and Supabase.
V8 JIT optimization patterns for writing high-performance JavaScript in Next.js server internals. Use when writing or reviewing hot-path code in app-render, stream-utils, routing, caching, or any per-request code path. Covers hidden classes / shapes, monomorphic call sites, inline caches, megamorphic deopt, closure allocation, array packing, and profiling with --trace-opt / --trace-deopt.
