cdesign-cli

Install a design language into your project with one command. The CLI for the cdesign design-spec marketplace — think skills.sh, but for design.

A design is a small package (design.md + tokens.json) distilled from a real product's UI. Installing one drops design.md into your project so your AI agent (Claude Code, Cursor, …) builds on-brand UI that follows the spec.

Usage

npx cdesign-cli add <slug>

For example:

npx cdesign-cli add vercel

This writes the package into ./.claude/designs/vercel/ (for Claude Code) and records an anonymous install. Then ask your agent to "follow the Vercel design in .claude/designs/vercel/design.md."

Options

| Flag | Description | | --- | --- | | -g, --global | Install into ~/<agent>/designs/ instead of the project. | | -a, --agent <name> | Target agent dir: claude-code (default), cursor, opencode, windsurf. | | --host <url> | Registry host. Defaults to $CDESIGN_HOST, then the public registry. | | --no-telemetry | Don't report the anonymous install. | | -h, --help | Show help. |

Configuration

By default the CLI fetches from the public cdesign registry, so npx cdesign-cli add vercel works out of the box. To point it at your own deployment, set the CDESIGN_HOST environment variable (or pass --host):

CDESIGN_HOST=https://your-cdesign-host npx cdesign-cli add vercel

Requirements

Node.js >= 18 (uses the built-in fetch). No dependencies.
