What problem does it solve? Codebases accumulate duplicated UI patterns, hard-coded style values, and inconsistent component variations that increase maintenance cost and visual inconsistency. This Skill identifies those repeated patterns and consolidates them into a shared design system with proper tokens, variants, and documentation. ## Core Features & Use Cases - Pattern Discovery: Scans a target feature or area to find repeated components, hard-coded colors/spacing/typography, and inconsistent implementations of the same concept. - Component & Token Extraction: Builds reusable components with typed props, variants, and accessibility support, plus semantically named design tokens. - Migration & Documentation: Replaces existing usages with shared versions, removes dead code, and updates component library documentation. - Use Case: A team notices three different button implementations across their React app. Use this Skill to consolidate them into one typed, accessible Button component with variants, migrate all call sites, and document it in the design system. ## Quick Start Ask the assistant to extract reusable components and design tokens from a specific feature directory into the shared design system.
