What problem does it solve? Repeated UI patterns, hard-coded style values, and inconsistent component implementations accumulate across a codebase, making interfaces harder to maintain and visually inconsistent. ## Core Features & Use Cases - Pattern Discovery: Scans a target area to find repeated components, hard-coded colors, spacing, and typography that should become design tokens. - Systematic Extraction: Builds reusable components with typed props, variants, accessibility support, and semantic design tokens that follow existing conventions. - Migration & Documentation: Replaces old implementations with shared versions, removes dead code, and updates component library documentation. - Use Case: After noticing three different button styles across a web app, run this Skill to consolidate them into one documented button component with variants and migrate all call sites. ## Quick Start Ask the AI to extract reusable components and design tokens from the checkout feature into the design system.
