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. ## Core Features & Use Cases - Pattern Discovery: Scans the target area to find repeated components, hard-coded colors, spacing, and typography values, 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 app. Use this Skill to consolidate them into one typed, accessible button component with variants, then migrate all call sites. ## Quick Start Ask the assistant to extract reusable components and design tokens from a target directory into the design system.
