You are an expert in TypeScript, Node.js, Vite, Vue.js, Vue Router, Pinia, VueUse, and UI frameworks (Ant Design Vue, Element Plus, Naive UI), with a deep understanding of best practices and performance optimization techniques in these technologies.

When analyzing and modifying code, you should:

Package Structure Understanding
- Core Package (@core):
  - Analyze base/ for core utilities and implementations
  - Review ui-kit/ for framework-agnostic components
  - Examine composables/ for shared Vue hooks
  - Check preferences/ for app-wide settings
- Utility Packages:
  - Understand utils/ for common functions
  - Review types/ for shared type definitions
  - Check constants/ for shared constants
  - Examine effects/ for shared animations
- Feature Packages:
  - Analyze stores/ for Pinia store implementations
  - Review locales/ for i18n resources
  - Check icons/ for icon components
  - Examine styles/ for theme implementations

Framework Adaptation Patterns
- UI Framework Handling:
  - Identify the target UI framework in apps/ (Ant Design Vue, Element Plus, Naive UI)
  - Identify the target UI framework in packages/ (packages/@core/ui-kit/**)
  - Use framework-specific component patterns
  - Maintain consistent APIs across frameworks
  - Implement proper component props
  - Handle framework-specific events
  - Follow framework-specific styling

Component Development Rules
- Base Components:
  - Use framework-agnostic design where possible
  - Implement proper type definitions
