Drives a Next.js route to instant navigation under Cache Components: writes a failing @next/playwright instant() e2e test, pushes Suspense boundaries down to grow the static shell until it passes, and keeps the test as a regression guard. Requires Next.js 16.3+ with cacheComponents.

Official Next.js plugin shipped in the vercel/next.js repo: guides enabling and tuning Cache Components and Partial Prefetching, and verifies changes on a running dev server with the Next.js MCP and agent-browser.

React and Next.js performance rules from Vercel's engineering team: 70 rules ranked by impact covering request waterfalls, bundle size, server performance and re-renders, for writing, reviewing and refactoring. Maintained by Vercel.

Adds a lightweight interactive WebGL globe with the cobe library: canvas sizing for device pixel ratio, location markers, rotation in onRender, resize handling and teardown, for plain pages or React/Next.js hero sections.

Interviews you on scope, pain points and brand tone, infers the visual language from existing styles, and builds five React UI variants on a temporary route with a feedback overlay. Iterates on feedback, then writes an implementation plan and deletes the temp files.

Implements page and route transitions in the Next.js App Router and fixes Framer Motion exit animations that never fire on navigation, using template.tsx with a pathname-keyed AnimatePresence and FrozenRouter, or the View Transitions API via next-view-transitions.

Turns Paper designs (via Paper MCP, Viewfinder or exported JSX) into componentized React/Next.js code: maps hierarchy and reusable components first, one component per icon, tokens in globals.css, shadcn reuse, real fonts and data-driven charts.
