Web Artifacts Builder
Official skill for building a self-contained web app as a single artifact.
Use it for
Interactive calculators, dashboards, and demos that must run from one file
Skip it if
Production front ends with auth, routing, or a build pipeline
What it is
An official skill for generating a working web application as a single artifact rather than a repository. It handles the container conventions, keeps dependencies to CDN imports, and closes with a runnable result. It is a prototyping tool: the output is meant to be clicked, not shipped.
Install
Clone the repository, then copy the skill folder into your agent's skills directory — ~/.claude/skills/ for Claude Code. Skills are plain files: no build step, no daemon.

Read the SKILL.md before you install. A good skill states when it applies, what it must not do, and how to verify the result. A skill that only lists adjectives will change the agent's tone without improving its output — skip those.
