What problem does it solve? Frontend developers frequently need to look up component APIs, import paths, theming options, and integration details across multiple UI libraries, and switching between Ant Design, Element Plus, Naive UI, and Arco Design documentation wastes time and causes API confusion. ## Core Features & Use Cases - Library Routing Index: Maps React and Vue 3 projects to the right component library with a selection guide comparing ecosystem, TypeScript support, and design language. - Per-Library Reference Docs: Provides installation, import patterns, theming, internationalization, and FAQ docs for antd 6.x, Element Plus 2.x, Naive UI 2.44, and Arco Design 2.66. - Cross-Library Component Comparison: Topic docs (form, data-display, feedback, navigation, layout, others) show side-by-side API differences such as Form field naming (name vs prop vs path vs field). - Use Case: When a user asks how to build a validated form with a date range picker in a Vue 3 + TypeScript project, the skill routes to Naive UI or Element Plus references and returns working code with correct import paths. ## Quick Start Ask how to use a specific component such as a table or form in Ant Design, Element Plus, Naive UI, or Arco Design and load the matching reference doc.
