Gives Claude a design system conscience. Exposes check_drift for MCP clients and check_design_drift for claude.ai via a keyless connector endpoint. Point it at your CSS and either a preset pack (Studio, Workbench, Terminal) or your own tokens extracted from Tailwind configs or CSS variables. It returns every off-palette color, off-scale radius, spacing, and type value with the closest matching token to swap in. The agent can then apply fixes on a branch for review. All checks are stateless and transient, nothing is stored. Free tier covers the Studio pack and rate-limited BYO checks. A $12 drift-check license removes the cap, or bundle it with premium packs at $19–$49.
