Summary

A short X post with a video demo of a /design command in Claude Code, Anthropic's coding assistant that runs in the terminal. The caption has only the command name. There is no transcript, so this note can't say what the command does or how it works.

Key points

• Claude Code has slash commands that you type in its terminal session. The post shows one called /design.
• The caption doesn't explain what /design does or how to set it up. Only the video shows it.
• Check the Claude Code docs to see whether /design is a built-in command or a custom one before you rely on it.
