Web Artifacts Builder is an example skill in Anthropic's skills repository for building multi-component claude.ai HTML artifacts. Its SKILL.md names the stack as React 18, TypeScript, Vite, Parcel for bundling, Tailwind CSS and shadcn/ui, with more than 40 shadcn components preinstalled. The workflow is a script to initialise a project, editing the generated code, and a second script that bundles everything into a single HTML file to show the user. It says to avoid common AI slop such as centered layouts, purple gradients and uniform rounded corners. It is meant for artifacts needing state, routing or shadcn components, and not for simple single-file pages. The folder LICENSE.txt is Apache 2.0 and the install route in the draft is /plugin marketplace add anthropics/skills. The repository was last pushed on 28 October 2026. A limit is that its output targets claude.ai artifacts. We have not run it ourselves for this note.
