A health score, receipts, fixes ranked by payoff, rules injected via --apply, and now a local MCP server via --mcp: your agent asks before writing UI, gets checked after. Benchmarked against 34 public repos and 10 reputable systems.

README Excerpt

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. > **New in 5.0: it runs as a local MCP server.** One command, and your agent asks the design system before writing UI, then gets the work checked after: which Button is canonical, which token holds that colour, review my changes. Local, deterministic, nothing leaves your machine. See [Live answers over MCP](#live-answers-over-mcp).
