Agent Skills

A collection of skills for AI coding agents. Skills are packaged instructions and scripts that extend agent capabilities. This skill set provides ready-to-use expertise for common development tasks, allowing AI agents to perform audits, reviews, deployments, and optimizations directly from conversations.

Who Is This For

Developers using AI coding agents (such as Claude Code, Codex, or similar) who want to enhance their agent's capabilities with pre-built, expert-level instructions for Vercel optimization, React best practices, web design guidelines, writing guidelines, React Native guidelines, view transitions, composition patterns, and instant deployment.

Available Skills

vercel-optimize

Audits a Vercel project for cost, performance, reliability, caching, function usage, and billing opportunities. It collects Vercel metrics first, then investigates only the routes and files those metrics point to.

Use when:

• Optimizing a deployed Vercel project
• Reducing Vercel costs or function usage
• Investigating slow or expensive routes
• Finding caching, ISR, middleware, image, or build-minute issues
• Producing a ranked cost and performance report

react-best-practices

React and Next.js performance optimization guidelines from Vercel Engineering. Contains 40+ rules across 8 categories, prioritized by impact.

Use when:

• Writing new React components or Next.js pages
• Implementing data fetching (client or server-side)
• Reviewing code for performance issues
• Optimizing bundle size or load times

Categories covered:

• Eliminating waterfalls (Critical)
• Bundle size optimization (Critical)
• Server-side performance (High)
• Client-side data fetching (Medium-High)
• Re-render optimization (Medium)
• Rendering performance (Medium)
• JavaScript micro-optimizations (Low-Medium)

web-design-guidelines

Review UI code for compliance with web interface best practices. Audits your code for 100+ rules covering accessibility, performance, and UX.

Use when:

• "Review my UI"

• "Audit design"
• "Review UX"
• "Check my site against best practices"

Categories covered:

• Accessibility (aria-labels, semantic HTML, keyboard handlers)
• Focus States (visible focus, focus-visible patterns)
• Forms (autocomplete, validation, error handling)
• Animation (prefers-reduced-motion, compositor-friendly transforms)
• Typography (curly quotes, ellipsis, tabular-nums)
• Images (dimensions, lazy loading, alt text)
• Performance (virtualization, layout thrashing, preconnect)
• Navigation & State (URL reflects state, deep-linking)
• Dark Mode & Theming (color-scheme, theme-color meta)
• Touch & Interaction (touch-action, tap-highlight)
• Locale & i18n (Intl.DateTimeFormat, Intl.NumberFormat)

writing-guidelines

Review docs and prose for compliance with the Vercel writing handbook. Audits your pages for 80+ rules covering voice, structure, content types, code samples, typography, and AI workflow.

Use when:

• "Review my docs"
• "Check writing style"
• "Audit prose"
• "Review docs voice and tone"
• "Check this page against the writing handbook"

Categories covered:

• Planning (content plan, content type, user-shaped titles)
• Voice & tone (active voice, direct address, banned words like easy/simple/quick)
• Tone by content type (tutorial, how-to, reference, conceptual, troubleshooting)
• Headings & structure (sentence case, descriptive subheadings, TL;DR opens)
• Lists (when to use, bold/description format)
• Code (language tags, TypeScript first, <Steps/>, 80-col / 25-line limits)
• Placeholders, units, & numbers (snake_case text, count-up numbers, 64 KB/200 ms)
• Typography (no em dashes as punctuation, curly quotes, ellipsis character, non-breaking spaces)
• Source formatting (no hard-wrap, no --- rules, blank line discipline)
• Pricing & money pages (tables, uncompromising detail)
• AI workflow (accountability, enterprise models, plan first, disclose AI use)
• Review (PR description discipline, author accountability)

react-native-guidelines

React Native best practices optimized for AI agents. Contains 16 rules across 7 sections covering performance, architecture, and platform-specific patterns.

Use when:

• Building React Native or Expo apps
• Optimizing mobile performance
• Implementing animations or gestures
• Working with native modules or platform APIs

Categories covered:

• Performance (Critical) - FlashList, memoization, heavy computation
• Layout (High) - flex patterns, safe areas, keyboard handling
• Animation (High) - Reanimated, gesture handling
• Images (Medium) - expo-image, caching, lazy loading
• State Management (Medium) - Zustand patterns, React Compiler
• Architecture (Medium) - monorepo structure, imports
• Platform (Medium) - iOS/Android specific patterns

react-view-transitions

Implement smooth, native-feeling animations using React's View Transition API. Covers the <ViewTransition> component, addTransitionType, transition types, and Next.js integration including the transitionTypes prop on next/link.

Use when:

• Adding page transitions or route animations
• Animating enter/exit of components
• Creating shared element transitions (list-to-detail morphing)
• Implementing directional (forward/back) navigation animations
• Integrating view transitions in Next.js App Router
• Animating list reorder or Suspense fallback reveals

Topics covered:

• <ViewTransition> component (enter, exit, update, share triggers)
• addTransitionType for directional/context-specific animations
• View Transition Classes and CSS pseudo-elements
• Shared element transitions with the name prop
• JavaScript animations via Web Animations API
• Next.js transitionTypes prop on next/link
• Ready-to-use CSS animation recipes (fade, slide, scale, flip)
• Accessibility (prefers-reduced-motion)

composition-patterns

React composition patterns that scale. Helps avoid boolean prop proliferation through compound components, state lifting, and internal composition.

Use when:

• Refactoring components with many boolean props
• Building reusable component libraries
• Designing flexible APIs
• Reviewing component architecture

Patterns covered:

• Extracting compound components
• Lifting state to reduce props
• Composing internals for flexibility
• Avoiding prop drilling

vercel-deploy-claimable

Deploy applications and websites to Vercel instantly. Designed for use with claude.ai and Claude Desktop to enable deployments directly from conversations. Deployments are "claimable" - users can transfer ownership to their own Vercel account.

Use when:

• "Deploy my app"
• "Deploy this to production"
• "Push this live"
• "Deploy and give me the link"

Features:

• Auto-detects 40+ frameworks from package.json
• Returns preview URL (live site) and claim URL (transfer ownership)
• Handles static HTML projects automatically
• Excludes node_modules and .git from uploads

How it works:

1. Packages your project into a tarball
2. Detects framework (Next.js, Vite, Astro, etc.)
3. Uploads to deployment service
4. Returns preview URL and claim URL

Output:

Deployment successful!

Preview URL: https://skill-deploy-abc123.vercel.app
Claim URL:   https://vercel.com/claim-deployment?code=...

How to Use

Skills are automatically available once installed. The agent will use them when relevant tasks are detected. You can trigger them by describing your task naturally, for example:

• "Deploy my app"
• "Review this React component for performance issues"
• "Help me optimize this Next.js page"

What You Need to Provide

• An AI coding agent environment (e.g., Claude Code, Codex, or similar) that supports Agent Skills.
• Access to the project you want to work on (local files, repository, or Vercel project).
• For Vercel-related skills, you may need appropriate permissions to your Vercel account.

What You Get

• Pre-built, expert-level instructions and scripts that guide the agent to perform specific tasks.
• Automated Vercel project audits, React performance reviews, UI design audits, writing style reviews, React Native optimization, view transition implementations, composition pattern refactoring, and instant deployments.
• For deployments: a preview URL (live site) and a claim URL to transfer ownership to your Vercel account.

Notes

• Deployments are "claimable" – you can transfer ownership to your own Vercel account after deployment.
• The vercel-optimize skill only investigates routes and files that metrics point to, not the entire project.
• The vercel-deploy-claimable skill excludes node_modules and .git from uploads.
• Skills are designed to work with AI coding agents; they are not standalone tools.
