Onsystem keeps Claude aligned with your React design system by reading components, props, variants and tokens, then catching and correcting invented UI elements via a post-edit hook and MCP server. It runs locally with zero config, integrates seamlessly alongside @shadcn/lint, and makes no network requests or API calls.
