What problem does it solve? Deploying to Vercel involves many branching decisions—git linking, team selection, CLI authentication, preview versus production—and React/Next.js code often ships with performance problems like waterfalls, bloated bundles, and unnecessary re-renders. This Skill routes both concerns to the right operational guidance. ## Core Features & Use Cases - Deployment orchestration: Detects project state (git remote, .vercel linking, CLI auth) and chooses the correct deploy path—git push, vercel deploy, or a no-auth fallback script for sandboxed environments. - Environment and team handling: Guides team scope selection, project linking (vercel link --repo), preview/production deploys, and deployment status inspection. - React/Next.js performance rules: Provides 70 prioritized rules across 8 categories (waterfalls, bundle size, server-side, data fetching, re-renders, rendering, JavaScript, advanced patterns) for writing and reviewing performant code. - Use Case: A developer asks to push a Next.js app live; the Skill checks linking and auth state, deploys a preview, returns the URL, and later reviews a slow page against the async-parallel and bundle-dynamic-imports rules. ## Quick Start Ask the assistant to deploy this project to Vercel as a preview and give you the deployment link.
