- [Next.js DevTools MCP](https://hebbmind.com/ja/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.
- [Vercel Plugin](https://hebbmind.com/ja/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.

- [Page Transition Animation](https://hebbmind.com/ja/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/ja/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.
