Package Manager Implementation

The package manager feature allows users to discover, browse, and manage Git-based package sources containing reusable components like modes, MCP servers, and prompts.

Core Components

Backend (VSCode Extension)

• PackageManagerManager: Central service that manages package sources, fetching, and caching
• GitFetcher: Handles Git operations for cloning and updating repositories
• MetadataScanner: Scans repositories for component metadata
• PackageManagerSourceValidation: Validates package manager source URLs and configurations

Frontend (Webview UI)

• PackageManagerView: React component for the package manager interface
• PackageManagerViewStateManager: Manages frontend state and synchronization with backend
• useStateManager: React hook for accessing the state manager

Key Features

• Git repository integration (HTTPS, SSH, Git protocol)
• Component metadata scanning and validation
• Source configuration management
• Caching and concurrent operation handling
• Component filtering and sorting
• Real-time state synchronization between frontend and backend
