What problem does it solve? Teams building conversion-focused interfaces often lack consistent, opinionated design guidance, leading to inconsistent spacing, low-contrast text, and ambiguous component behavior across products. ## Core Features & Use Cases - Design Token Foundations: Provides a defined palette (primary #27272A, secondary #8B5CF6, semantic success/warning/danger), Inter and JetBrains Mono typography scales, and a 4/8/12/16/24/32 spacing scale. - Component Rule Authoring: Guides creation of component anatomy, variants, states (hover, focus-visible, disabled, loading, error), and responsive behavior. - Accessibility & QA Gates: Enforces WCAG 2.2 AA requirements, testable acceptance criteria, anti-patterns, and a code-review QA checklist. - Use Case: A designer-engineer pair documenting a new checkout flow can generate consistent button, form, and error-state rules anchored to the Levels tokens. ## Quick Start Use the levels skill to write design system guidelines for a conversion-focused signup form with accessible button and input states.
