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 evolve. This Skill identifies those redundancies and consolidates them into a shared design system. ## Core Features & Use Cases - Pattern Discovery: Scans the target area for repeated components, hard-coded colors, spacing, and typography values, and inconsistent variations of the same UI concept. - Component & Token Extraction: Builds reusable components with typed props, variants, accessibility support, and semantic design tokens with clear naming hierarchies. - Systematic Migration: Replaces existing implementations with the shared versions, removes dead code, and updates design system documentation. - Use Case: A React codebase has three different button implementations and scattered hex color values. Use this Skill to consolidate them into a single Button component with variants and a semantic color token set, then migrate all call sites. ## Quick Start Ask the AI to extract the repeated UI patterns in the components directory into the design system and migrate existing usages.
