- [next-dev-loop](https://hebbmind.com/ko/skill/next-dev-loop.md): [Skill] After code changes, has the agent check routes, errors and page behavior in the running Next.js app via /_next/mcp and agent-browser to confirm the change really works. Maintained by Next.js; needs Next.js 16.3+ (Turbopack) and agent-browser.
- [Next.js Cache Components Optimizer](https://hebbmind.com/ko/skill/next-cache-components-optimizer.md): [Skill] 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.
- [Next.js Skills](https://hebbmind.com/ko/plugin/vercel-skills.md): [Plugin] 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.
- [Vercel Optimize](https://hebbmind.com/ko/skill/vercel-optimize.md): [Skill] Vercel's official cost and performance skill: gathers production metrics, usage and project config, investigates only the routes and files the metrics point to, and returns ranked, doc-backed recommendations. Supports Next.js, SvelteKit and Nuxt; needs Vercel CLI v53+ logged in and linked.
- [Vercel React Best Practices](https://hebbmind.com/ko/skill/react-best-practices.md): [Skill] 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.
- [Cobe.js](https://hebbmind.com/ko/skill/cobejs.md): [Skill] 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.
- [Next.js DevTools MCP](https://hebbmind.com/ko/mcp/next-devtools-mcp.md): [MCP] From Vercel: discovers locally running Next.js 16+ dev servers and hands the runtime errors, routes and logs from their built-in MCP endpoint to the agent, and points the agent to docs matching your installed version.
- [Design Lab](https://hebbmind.com/ko/skill/design-lab.md): [Skill] 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.
- [Vercel Plugin](https://hebbmind.com/ko/plugin/vercel-plugin.md): [Plugin] Vercel's official plugin: a knowledge graph of the Vercel ecosystem, dozens of skills, expert subagents for deployment and performance, and commands for deploys, env vars and project status, covering Next.js, the AI SDK, storage and CI/CD. Needs Node.js 18+ and Bun; telemetry is opt-out.
- [Page Transition Animation](https://hebbmind.com/ko/skill/page-transition-animation.md): [Skill] 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.
- [Budge](https://hebbmind.com/ko/skill/budge.md): [Skill] When the agent changes a single CSS value or Tailwind class in a Next.js App Router project, a floating bar appears on the page so you can fine-tune it with arrow keys before persisting. Loads a runtime script from budge.design in app/layout.tsx.
- [Paper to Code Components](https://hebbmind.com/ko/skill/paper-to-code-components.md): [Skill] 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.
