What problem does it solve? Teams building modern minimalist interfaces often lack consistent, implementation-ready design guidance, leading to inconsistent spacing, ambiguous component states, and accessibility gaps. This Skill turns the Sleek design language into concrete, testable rules engineers and designers can apply directly. ## Core Features & Use Cases - Token-Driven Foundations: Provides the full Sleek palette (primary #3B82F6, secondary #8B5CF6, semantic colors), Inter/JetBrains Mono typography scale, and 8pt spacing grid as authoritative tokens. - Component Rule Authoring: Defines anatomy, variants, states (default, hover, focus-visible, active, disabled, loading, error), and responsive behavior for UI components. - Accessibility & QA Gates: Enforces WCAG 2.2 AA requirements, testable acceptance criteria, anti-patterns, and a code-review-ready QA checklist. - Use Case: Ask for button component guidelines and receive token-anchored rules covering every interaction state, keyboard behavior, contrast requirements, and migration notes for legacy styles. ## Quick Start Use the sleek skill to write design-system guidelines for a primary button component including all interaction states and accessibility criteria.
