Artifacts Builder

Toolkit for creating sophisticated, multi-component HTML artifacts optimized for Claude.ai using contemporary frontend technologies including React 18, TypeScript, Vite, Tailwind CSS 3.4.1, and the shadcn/ui component library.

When to Use This Skill

Use this skill when users request complex artifacts requiring:

• State management capabilities
• Routing functionality
• shadcn/ui component library components
• Multi-component React architectures

Do NOT use for:

• Simple single-file HTML artifacts
• Basic JSX components without complex dependencies
• Quick prototypes that don't require the full React + TypeScript stack

Technology Stack

The initialization process automatically provides:

• React 18 with TypeScript
• Vite for development (version-compatible with Node.js version)
• Parcel for production bundling
• Tailwind CSS 3.4.1 with custom theming
• shadcn/ui with 40+ pre-installed components
• Radix UI primitives and dependencies
• Path aliases using @/ notation
• Dark mode support via CSS variables
• Node 18+ compatibility

Core Workflow

Follow these five steps to create and share artifacts:

Step 1: Initialize Project

Run the initialization script to create a new React project with all dependencies configured:

bash scripts/init-artifact.sh <project-name>

What this does:

• Validates Node.js 18+ installation
• Creates Vite React TypeScript project
• Installs and configures Tailwind CSS with shadcn theming
• Sets up path aliases (@/* for src/)
• Extracts 40+ pre-installed shadcn/ui components
• Configures dark mode support
• Creates components.json configuration

Requirements:

• Node.js 18 or higher
• The shadcn-components.tar.gz file must be present in the scripts/ directory
  • Important: Download this file from https://github.com/anthropics/skills/tree/main/artifacts-builder/scripts
  • Place it in .claude/skills/artifacts-builder/scripts/ before running init-artifact.sh

Step 2: Develop the Artifact

After initialization, modify the generated files to build your artifact:

• Edit src/App.tsx for your main application logic
• Create components in src/components/
• Use pre-installed shadcn/ui components via @/components/ui/
• Style with Tailwind CSS classes and CSS variables

Available Components (40+ total):

• Layout: accordion, aspect-ratio, card, collapsible, resizable, scroll-area, separator, sheet, tabs
• Forms: button, checkbox, form, input, label, radio-group, select, slider, switch, textarea
• Navigation: breadcrumb, command, context-menu, dropdown-menu, menubar, navigation-menu
• Feedback: alert, badge, progress, skeleton, sonner, toast
• Overlays: dialog, drawer, hover-card, popover, tooltip
• Data: calendar, carousel, table
• Other: avatar, toggle, toggle-group

Import pattern:

import { Button } from '@/components/ui/button'
import { Card, CardHeader, CardTitle, CardContent } from '@/components/ui/card'
import { Dialog, DialogContent, DialogTrigger } from '@/components/ui/dialog'

Step 3: Bundle into Single HTML

When development is complete, create a self-contained HTML artifact:

bash scripts/bundle-artifact.sh

What this does:

• Installs Parcel and bundling dependencies
• Creates .parcelrc configuration with TypeScript path alias support
• Cleans previous builds
• Builds optimized production bundle (no source maps)
• Inlines all JavaScript, CSS, and assets into single HTML file
• Outputs bundle.html with file size information

Output: A single bundle.html file containing the complete React application with all dependencies embedded inline, suitable for sharing in Claude conversations.

Step 4: Share the Artifact

Use the generated bundle.html file as an artifact in Claude conversations or share it directly with users. The file is:

• Self-contained (no external dependencies)
• Portable (works in any modern browser)
• Optimized (production build with minification)

Step 5: Test/Visualize (Optional)

Test the artifact by opening bundle.html in a browser. Only recommended if issues arise during development or if verification is needed before sharing.

Design Guidance

Avoid creating "AI slop" aesthetics. Specifically avoid:

• Excessive centered layouts
• Purple gradients as default theme
• Uniform rounded corners everywhere
• Inter font as the only typeface

Instead, create intentional, varied designs that match the artifact's purpose and context.

Available Scripts

scripts/init-artifact.sh

Initializes a new React + Vite + shadcn/ui project with full configuration.

Usage: bash scripts/init-artifact.sh <project-name>

Features:

• Node version detection and Vite version compatibility
• Cross-platform support (macOS/Linux)
• Automatic pnpm installation if unavailable
• Complete Tailwind CSS setup with shadcn theme
• Path alias configuration in TypeScript
• 40+ shadcn/ui components extraction

scripts/bundle-artifact.sh

Bundles the React application into a single HTML file.

Usage: bash scripts/bundle-artifact.sh (run from project root)

Requirements:

• Must be run from project directory containing package.json
• Requires index.html in project root

Output: bundle.html in project root

Resources

• shadcn/ui Documentation: https://ui.shadcn.com/docs/components
• Component Examples: Browse shadcn/ui docs for usage patterns and props
• Tailwind CSS: https://tailwindcss.com/docs
• React Documentation: https://react.dev

Installation Notes

First-time Setup:

1. Download shadcn-components.tar.gz from Anthropic's skills repository
2. Place it in .claude/skills/artifacts-builder/scripts/
3. Verify scripts have executable permissions: chmod +x scripts/*.sh

System Requirements:

• Node.js 18+ (Node 20+ recommended for latest Vite)
• macOS or Linux (cross-platform sed support)
• pnpm (installed automatically if missing)

Troubleshooting

"shadcn-components.tar.gz not found"

• Download from https://github.com/anthropics/skills/tree/main/artifacts-builder/scripts
• Place in .claude/skills/artifacts-builder/scripts/

"Node.js 18 or higher is required"

• Update Node.js: https://nodejs.org/

Bundle size too large

• Review included dependencies
• Consider code splitting for very large applications
• Remove unused shadcn/ui components if needed

Path alias not resolving

• Verify tsconfig.json and tsconfig.app.json have baseUrl and paths configured
• Check .parcelrc includes parcel-resolver-tspaths

Examples

Basic Usage:

# Initialize project
bash scripts/init-artifact.sh my-dashboard

# Develop application
cd my-dashboard
pnpm dev

# Bundle when ready
bash scripts/bundle-artifact.sh

Using Components:

import { Button } from '@/components/ui/button'
import { Card, CardContent, CardHeader, CardTitle } from '@/components/ui/card'

function App() {
  return (
    <Card>
      <CardHeader>
        <CardTitle>My Dashboard</CardTitle>
      </CardHeader>
      <CardContent>
        <Button>Click me</Button>
      </CardContent>
    </Card>
  )
}
