What problem does it solve? Teams building minimalist two-dimensional interfaces often lack consistent, opinionated guidance for applying Flat design tokens, component states, and accessibility requirements, leading to inconsistent UI implementations. ## Core Features & Use Cases - Design Token Foundations: Provides a complete Flat style foundation including color tokens (primary #F2673C, secondary #8B5CF6), Inter and JetBrains Mono typography scales, and 4/8/12/16/24/32 spacing scales. - Component Rule Authoring: Guides creation of component anatomy, variants, states (default, hover, focus-visible, active, disabled, loading, error), and responsive behavior rules. - Accessibility Enforcement: Embeds WCAG 2.2 AA requirements, keyboard-first interactions, and testable acceptance criteria into every guideline. - Use Case: A designer-engineer pair needs to document a button component for a Flat-style product; the Skill produces token-anchored rules, anti-patterns, migration notes, and a QA checklist ready for code review. ## Quick Start Ask the AI to generate Flat design system guidelines for a specific component such as a form input or navigation bar.
