The agent-skills repository is Vercel's official collection of packaged instructions and scripts designed to extend the capabilities of AI coding agents. Following the Agent Skills format, this repository provides a curated set of specialized tools that agents can leverage to perform complex tasks across web development, optimization, and deployment workflows.
The repository contains seven primary skills, each targeting specific use cases. The vercel-optimize skill audits deployed Vercel projects for cost, performance, reliability, caching, function usage, and billing opportunities by collecting Vercel metrics and investigating only the routes and files those metrics identify. The react-best-practices skill packages over 40 performance optimization rules across 8 categories prioritized by impact, drawn from Vercel Engineering's experience with React and Next.js applications. These rules span eliminating waterfalls, bundle size optimization, server-side performance, client-side data fetching, re-render optimization, rendering performance, and JavaScript micro-optimizations.
The web-design-guidelines skill audits UI code against over 100 rules covering accessibility, performance, and UX best practices. Its coverage includes accessibility standards like aria-labels and semantic HTML, focus states, form handling, animation best practices, typography conventions, image optimization, performance patterns, navigation and state management, dark mode and theming, touch interactions, and internationalization considerations. The writing-guidelines skill reviews documentation and prose against Vercel's writing handbook, enforcing 80+ rules across voice, structure, content types, code samples, typography, and AI workflow considerations. This includes planning guidance, voice and tone standards, content-type-specific guidance, heading and structure conventions, list formatting, code documentation standards, placeholder and number formatting, typography rules, source formatting discipline, pricing page standards, and AI workflow accountability.
The react-native-guidelines skill provides 16 best practice rules optimized for AI agents building React Native and Expo applications, covering performance, layout, animation, images, state management, architecture, and platform-specific patterns. The react-view-transitions skill enables smooth animations using React's View Transition API, covering the ViewTransition component, transition types, shared element transitions, and Next.js App Router integration. The composition-patterns skill teaches React composition patterns that scale, helping developers avoid boolean prop proliferation through compound components, state lifting, and internal composition strategies.
The vercel-deploy-claimable skill enables direct deployment of applications to Vercel, designed for use with claude.ai and Claude Desktop. It auto-detects over 40 frameworks from package.json, handles static HTML projects, excludes node_modules and .git directories, and returns both a preview URL for the live site and a claim URL allowing users to transfer ownership to their own Vercel account.
