Cline Extension Architecture

This directory contains architectural documentation for the Cline VSCode extension.

Extension Architecture Diagram

The extension-architecture.mmd file contains a Mermaid diagram showing the high-level architecture of the Cline extension. The diagram illustrates:

1. Core Extension

   • Extension entry point and main classes
   • State management through VSCode's global state and secrets storage
   • Core business logic in the Cline class

2. Webview UI

   • React-based user interface
   • State management through ExtensionStateContext
   • Component hierarchy

3. Storage

   • Task-specific storage for history and state
   • Git-based checkpoint system for file changes

4. Data Flow

   • Core extension data flow between components
   • Webview UI data flow
   • Bidirectional communication between core and webview

Viewing the Diagram

To view the diagram:

1. Install a Mermaid diagram viewer extension in VSCode
2. Open extension-architecture.mmd
3. Use the extension's preview feature to render the diagram

You can also view the diagram on GitHub, which has built-in Mermaid rendering support.

Color Scheme

The diagram uses a high-contrast color scheme for better visibility:

• Pink (#ff0066): Global state and secrets storage components
• Blue (#0066ff): Extension state context
• Green (#00cc66): Cline provider
• All components use white text for maximum readability
