anthropicsSuite 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.

Install with your agent
Paste this prompt into your agent. It reads this page and does the setup for you.
Read https://aiagentslisting.com/skill/web-artifacts-builder to learn what the "Web Artifacts Builder" skill does and how to install it. Install it for my coding agent as documented on that page, then confirm the skill is available and summarize what it can do.Agents can also browse this directory over MCP at https://aiagentslisting.com/api/mcp
Install manually
Claude Code
- Run the install command below in your terminal.
- The skill files land in your ~/.claude/skills directory, laid out as shown.
- Restart Claude Code or start a new session. Skills are discovered on startup.
git clone --depth 1 https://github.com/anthropics/skills.git /tmp/web-artifacts-builder
mkdir -p ~/.claude/skills
cp -r /tmp/web-artifacts-builder/skills/web-artifacts-builder ~/.claude/skills/web-artifacts-builder
rm -rf /tmp/web-artifacts-builder~/.claude/skills/web-artifacts-builder

Any other agent
- Clone the repository with the command below.
- Copy the skill folder into the directory your agent loads skills from.

To build powerful frontend claude.ai artifacts, follow these steps:
- Initialize the frontend repo using
scripts/init-artifact.sh - Develop your artifact by editing the generated code
- Bundle all code into a single HTML file using
scripts/bundle-artifact.sh - Display artifact to user
- (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 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)
Step 2: Develop Your Artifact
To build the artifact, edit the generated files. See Common Development Tasks below for guidance.
Step 3: Bundle to Single HTML File
To bundle the React app into a single HTML artifact:
bash scripts/bundle-artifact.shThis creates bundle.html - a self-contained artifact with all JavaScript, CSS, and dependencies inlined. This file can be directly shared in Claude conversations as an artifact.
Requirements: Your project must have an index.html in the root directory.
What the script does:
- Installs bundling dependencies (parcel, @parcel/config-default, parcel-resolver-tspaths, html-inline)
- Creates
.parcelrcconfig with path alias support - Builds with Parcel (no source maps)
- Inlines all assets into single HTML using html-inline
Step 4: Share Artifact with User
Finally, share the bundled HTML file in conversation with the user so they can view it as an artifact.
Step 5: Testing/Visualizing the Artifact (Optional)
Note: This is a completely optional step. Only perform if necessary or requested.
To test/visualize the artifact, use available tools (including other Skills or built-in tools like Playwright or Puppeteer). In general, avoid testing the artifact upfront as it adds latency between the request and when the finished artifact can be seen. Test later, after presenting the artifact, if requested or if issues arise.
