Suite of tools for creating elaborate, multi-component claude.ai HTML artifacts using modern frontend web technologies (React, Tailwind CSS, shadcn/ui). Use for complex artifacts requiring state management, routing, or shadcn/ui components - not for simple single-file HTML/JSX artifacts.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Web Artifacts Builder

To build powerful frontend claude.ai artifacts, follow these steps:
1. Initialize the frontend repo using `scripts/init-artifact.sh`
2. Develop your artifact by editing the generated code
3. Bundle all code into a single HTML file using `scripts/bundle-artifact.sh`
4. Display artifact to user
5. (Optional) Test the artifact

**Stack**: React 18 + TypeScript + Vite + Parcel (bundling) + Tailwind CSS + shadcn/ui

## Design & Style Guidelines

VERY IMPORTANT: To avoid what is often referred to as "AI slop", avoid using excessive centered layouts, purple gradients, uniform rounded corners, and Inter font.

## Quick Start

### Step 1: Initialize Project

Run the initialization script to create a new React project:
```bash
bash scripts/init-artifact.sh <project-name>
cd <project-name>
```

This creates a fully configured project with:
- ✅ React + TypeScript (via Vite)
- ✅ Tailwind CSS 3.4.1 with shadcn/ui theming system
- ✅ Path aliases (`@/`) configured
- ✅ 40+ shadcn/ui components pre-installed
- ✅ All Radix UI dependencies included
- ✅ Parcel configured for bundling (via .parcelrc)
- ✅ Node 18+ compatibility (auto-detects and pins Vite version)
