vercel-labs / cursor-plugin

The skill, vercel-react-best-practices, organizes 57 performance rules into eight categories ranked by impact — eliminating waterfalls and bundle-size work sit at critical priority, server-side performance is high, client-side data fetching and re-render optimization sit in the middle, and JavaScript performance and advanced patterns rank lowest — and it activates automatically when you write, review, or refactor React or Next.js code. The command, /vercel-deploy, walks through installing the Vercel CLI, authenticating, and running either a preview or a production deployment.

It is for a narrow, specific pairing: Cursor as the editor, React or Next.js as the framework, and Vercel as the deploy target — nothing here is useful outside that combination. The rules themselves are not stored in this repository: the skill fetches them live from vercel-labs/agent-skills on GitHub every time it runs, so the plugin always reflects the latest rule set without needing its own updates, but that also means the guidance depends on that other repository staying in place and reachable.
