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.

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.

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.

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.

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.
