Claude Code gets a /design command that lets developers create UI mockups right in the terminal

Anthropic has released an early preview of the /design command in Claude Code. The new feature lets developers create design mockups directly in the terminal or desktop app before they start writing code. A sample command looks like "/design a few options for {feature}" and Claude generates multiple drafts as artboards. Users can pick their favorite, edit it, and then build it out.

According to developer Nate Parrott, Claude reads the existing codebase, matches the current UI style, and creates shareable mockups as Artifacts. The editor and prompting features come from Claude Design and are now built directly into Claude Code. The designs carry over into the build step, but they still need to be saved manually for now. To try it out, just run "claude update."
