Claude Code, Anthropic's AI-powered coding assistant, has added a new /design command that enables developers to create UI mockups directly in the terminal. The CLI-based tool already assists with code writing, debugging, and file management; the new feature targets developers who need quick visual prototypes without switching between their coding environment and separate design applications.
What Happened
Anthropic has introduced a /design command to Claude Code, its CLI-based coding agent. The feature allows developers to generate user interface mockups without leaving their terminal environment. According to the report from The Decoder, the command streamlines the workflow for creating visual prototypes during development by integrating design capabilities directly into the command-line interface where developers already work.
Why It Matters
For developers, the ability to produce UI mockups within an existing CLI workflow reduces context-switching between tools. Rather than opening a separate design application or web-based prototyping tool, developers can generate and iterate on visual designs using natural language prompts in their terminal. This tightens the feedback loop between design intent and implementation, particularly for teams building internal tooling or rapid prototypes where lightweight mockups suffice.
The Bottom Line
Anthropic's addition of a /design command to Claude Code brings generative AI capabilities into the early stages of UI development workflows, allowing developers to produce mockups without leaving their coding environment. The feature is available now through Claude Code, with documentation on Anthropic's developer platform.
