What problem does it solve? Teams building interfaces in the Claude visual style often lack concrete, enforceable rules, leading to inconsistent spacing, color misuse, and accessibility gaps across components. ## Core Features & Use Cases - Design Token Foundations: Defines the Claude palette (warm ivory surfaces, near-black ink, earthy accents), typography scale, and spacing rhythm as reusable tokens. - Component Rule Authoring: Produces component-level guidance covering anatomy, variants, states (hover, focus-visible, disabled, loading, error), and responsive behavior. - Accessibility & QA Gates: Enforces WCAG 2.2 AA requirements with testable acceptance criteria and a code-review-ready QA checklist. - Use Case: A designer-engineer pair standardizing a new dashboard asks for Claude-style button and card rules, and receives token-anchored specs with do/don't examples and migration notes for legacy components. ## Quick Start Ask the assistant to generate Claude design system guidelines for buttons and cards following the defined tokens and accessibility rules.
