Roast My Design System MCP Server

A free CLI tool (and Claude Code skill) that roasts your repo's design system with real data, then generates the rules that keep your AI agent on-system. It runs locally over stdio via the published package.

People connecting developer tools tools to Claude, Cursor, VS Code, or another MCP client. The project is written in JavaScript.
