+### Core Extension Architecture
+
+The core extension follows a clear hierarchical structure:
+
+1. **WebviewProvider** (src/core/webview/index.ts): Manages the webview lifecycle and communication
+2. **Controller** (src/core/controller/index.ts): Handles webview messages and task management
+3. **Task** (src/core/task/index.ts): Executes API requests and tool operations
+
+This architecture provides clear separation of concerns:
+- WebviewProvider focuses on VSCode webview integration
+- Controller manages state and coordinates tasks
+- Task handles the execution of AI requests and tool operations
+
+### WebviewProvider Implementation
+
+The WebviewProvider class in `src/core/webview/index.ts` is responsible for:
+
+- Managing multiple active instances through a static set (`activeInstances`)
+- Handling webview lifecycle events (creation, visibility changes, disposal)
+- Implementing HTML content generation with proper CSP headers
+- Supporting Hot Module Replacement (HMR) for development
+- Setting up message listeners between the webview and extension
+
+The WebviewProvider maintains a reference to the Controller and delegates message handling to it. It also handles the creation of both sidebar and tab panel webviews, allowing Cline to be used in different contexts within VSCode.

+- Secrets storage for sensitive information
+- Event listeners for file changes and configuration updates
+
+The Controller implements methods for:
+- Saving and loading task state
+- Managing API configurations
+- Handling user authentication
+- Coordinating MCP server connections

+## API Provider System
+
+Cline supports multiple AI providers through a modular API provider system. Each provider is implemented as a separate module in the `src/api/providers/` directory and follows a common interface.
+
+### API Provider Architecture
+
+The API system consists of:
+
+1. **API Handlers**: Provider-specific implementations in `src/api/providers/`
+2. **API Transformers**: Stream transformation utilities in `src/api/transform/`
+3. **API Configuration**: User settings for API keys and endpoints
+4. **API Factory**: Builder function to create the appropriate handler
+
+Key providers include:
+- **Anthropic**: Direct integration with Claude models
+- **OpenRouter**: Meta-provider supporting multiple model providers
+- **AWS Bedrock**: Integration with Amazon's AI services
+- **Gemini**: Google's AI models
+- **Ollama**: Local model hosting
+- **LM Studio**: Local model hosting
+- **VSCode LM**: VSCode's built-in language models
+
+### API Configuration Management
+
+API configurations are stored securely:
+- API keys are stored in VSCode's secrets storage
+- Model selections and non-sensitive settings are stored in global state
+- The Controller manages switching between providers and updating configurations
+
+The system supports:
+- Secure storage of API keys
+- Model selection and configuration
+- Automatic retry and error handling
+- Token usage tracking and cost calculation
+- Context window management
+
+### Plan/Act Mode API Configuration
+
+Cline supports separate model configurations for Plan and Act modes:
+- Different models can be used for planning vs. execution
+- The system preserves model selections when switching modes
+- The Controller handles the transition between modes and updates the API configuration accordingly
+
+## Task Execution System
+
+The Task class is responsible for executing AI requests and tool operations. Each task runs in its own instance of the Task class, ensuring isolation and proper state management.

+### Context Management System
+
+The Context Management System handles conversation history truncation to prevent context window overflow errors. Implemented in the `ContextManager` class, it ensures long-running conversations remain within model context limits while preserving critical context.
+
+Key features:
+
+1. **Model-Aware Sizing**: Dynamically adjusts based on different model context windows (64K for DeepSeek, 128K for most models, 200K for Claude).
+
+2. **Proactive Truncation**: Monitors token usage and preemptively truncates conversations when approaching limits, maintaining buffers of 27K-40K tokens depending on the model.
+
+3. **Intelligent Preservation**: Always preserves the original task message and maintains the user-assistant conversation structure when truncating.
+
+4. **Adaptive Strategies**: Uses different truncation strategies based on context pressure - removing half of the conversation for moderate pressure or three-quarters for severe pressure.
+
+5. **Error Recovery**: Includes specialized detection for context window errors from different providers with automatic retry and more aggressive truncation when needed.

+## Plan/Act Mode System
+
+Cline implements a dual-mode system that separates planning from execution:
+
+### Mode Architecture
+
+The Plan/Act mode system consists of:
+
+1. **Mode State**: Stored in `chatSettings.mode` in the Controller's state
+2. **Mode Switching**: Handled by `togglePlanActModeWithChatSettings` in the Controller
+3. **Mode-specific Models**: Optional configuration to use different models for each mode
+4. **Mode-specific Prompting**: Different system prompts for planning vs. execution
+
+### Mode Switching Process
+
+When switching between modes:
+
+1. The current model configuration is saved to mode-specific state
+2. The previous mode's model configuration is restored
+3. The Task instance is updated with the new mode
+4. The webview is notified of the mode change
+5. Telemetry events are captured for analytics
+
+### Plan Mode
+
+Plan mode is designed for:
+- Information gathering and context building
+- Asking clarifying questions
+- Creating detailed execution plans
+- Discussing approaches with the user
+
+In Plan mode, the AI uses the `plan_mode_respond` tool to engage in conversational planning without executing actions.
+
+### Act Mode
+
+Act mode is designed for:
+- Executing the planned actions
+- Using tools to modify files, run commands, etc.
+- Implementing the solution
+- Providing results and completion feedback
+
+In Act mode, the AI has access to all tools except `plan_mode_respond` and focuses on implementation rather than discussion.

+## MCP (Model Context Protocol) Integration
+
+### MCP Architecture
+
+The MCP system consists of:
+
+1. **McpHub Class**: Central manager in `src/services/mcp/McpHub.ts`
+2. **MCP Connections**: Manages connections to external MCP servers
+3. **MCP Settings**: Configuration stored in a JSON file
+4. **MCP Marketplace**: Online catalog of available MCP servers
+5. **MCP Tools & Resources**: Capabilities exposed by connected servers
+
+The McpHub class:
+- Manages the lifecycle of MCP server connections
+- Handles server configuration through a settings file
+- Provides methods for calling tools and accessing resources
+- Implements auto-approval settings for MCP tools
+- Monitors server health and handles reconnection
+
+### MCP Server Types
+
+Cline supports two types of MCP server connections:
+- **Stdio**: Command-line based servers that communicate via standard I/O
+- **SSE**: HTTP-based servers that communicate via Server-Sent Events
+
+### MCP Server Management
+
+The McpHub class provides methods for:
+- Discovering and connecting to MCP servers
+- Monitoring server health and status
+- Restarting servers when needed
+- Managing server configurations
+- Setting timeouts and auto-approval rules
+
+### MCP Tool Integration
+
+MCP tools are integrated into the Task execution system:
+- Tools are discovered and registered at connection time
+- The Task class can call MCP tools through the McpHub
+- Tool results are streamed back to the AI
+- Auto-approval settings can be configured per tool
+
+### MCP Marketplace
+
+The MCP Marketplace provides:
+- A catalog of available MCP servers
+- One-click installation
+- README previews
+- Server status monitoring
+
+The Controller class manages MCP servers through the McpHub service:
+
+```typescript
+class Controller {
+  mcpHub?: McpHub
+
+  constructor(context: vscode.ExtensionContext, outputChannel: vscode.OutputChannel, webviewProvider: WebviewProvider) {
+    this.mcpHub = new McpHub(this)
+  }
+
+  async downloadMcp(mcpId: string) {
+    // Fetch server details from marketplace
+    const response = await axios.post<McpDownloadResponse>(
+      "https://api.cline.bot/v1/mcp/download",
+      { mcpId },
+      {
+        headers: { "Content-Type": "application/json" },
+        timeout: 10000,
+      }
+    )
+
+    // Create task with context from README
+    const task = `Set up the MCP server from ${mcpDetails.githubUrl}...`
+
+    // Initialize task and show chat view
+    await this.initClineWithTask(task)
+  }
+}
+```
+
 ## Conclusion
 
 This guide provides a comprehensive overview of the Cline extension architecture, with special focus on state management, data persistence, and code organization. Following these patterns ensures robust feature implementation with proper state handling across the extension's components.
 
 Remember:
 - Always persist important state in the extension
-- The core extension exists in the src/ folder
+- The core extension follows a WebviewProvider -> Controller -> Task flow
 - Use proper typing for all state and messages
 - Handle errors and edge cases
 - Test state persistence across webview reloads

+# Cline Mentions Feature Guide
+
+## Overview
+
+The mentions feature is a powerful capability that allows you to reference various resources in your conversations with Cline using the "@" symbol. This includes file contents, directory structures, webpage URLs, VSCode diagnostic information, terminal output, Git change status, and more - all easily incorporated into your conversations.
+
+By using this feature, Cline can gain more accurate context and provide more relevant assistance for your tasks.
+
+## Basic Syntax
+
+Mentions always start with the "@" symbol, followed by the path or identifier of the resource you want to reference:
+
+```
+@resource_identifier
+```
+
+You can place mentions anywhere in your user messages, and Cline will automatically retrieve the referenced content.
+
+## Supported Mention Types
+
+### 1. File References
+
+To reference file contents, use `@/` followed by the relative path within your project:
+
+```
+@/path/to/file.js
+```
+
+**Example:**
+```
+Please analyze the implementation in @/src/components/Button.tsx
+```
+
+In this example, Cline automatically retrieves the contents of Button.tsx and uses it to perform the analysis.
+
+### 2. Directory References
+
+To reference directory contents, use `@/` followed by the relative path of the directory, ending with a trailing `/`:
+
+```
+@/path/to/directory/
+```
+
+**Example:**
+```
+What components are available in the @/src/components/ directory?
+```
+
+In this example, Cline retrieves a listing of the components directory and its contents.
+
+### 3. URL References
+
+To reference web page contents, use `@` followed by the URL:
+
+```
+@https://example.com
+```
+
+**Example:**
+```
+Please parse the JSON response from @https://api.github.com/users/octocat
+```
+
+In this example, Cline fetches the response from the GitHub API and analyzes the JSON.
+
+### 4. Diagnostic References
+
+To reference VSCode diagnostic information (errors and warnings) in the current workspace, use `@problems`:
+
+```
+@problems
+```
+
+**Example:**
+```
+Check @problems and tell me which errors I should prioritize fixing
+```
+
+In this example, Cline retrieves the current errors and warnings from your workspace and identifies high-priority issues.
+
+### 5. Terminal Output References
+
+To reference the latest terminal output, use `@terminal`:
+
+```
+@terminal
+```
+
+**Example:**
+```
+Please identify the cause of the error in the @terminal output
+```
+
+In this example, Cline examines the latest terminal output and analyzes the error's cause.
+
+### 6. Git Working Directory References
+
+To reference the current Git working directory change status, use `@git-changes`:
+
+```
+@git-changes
+```
+
+**Example:**
+```
+Review the @git-changes and summarize the important changes that should be committed
+```
+
+In this example, Cline retrieves the list of changed files in the current Git working directory and identifies candidates for commit.
+
+### 7. Git Commit References
+
+To reference information about a specific Git commit, use `@` followed by the commit hash:
+
+```
+@commit_hash
+```
+
+**Example:**
+```
+Analyze the commit @abcd123 and explain what changes were made
+```
+
+In this example, Cline retrieves information about the specified commit hash and analyzes the changes made in that commit.
+
+## Usage Scenarios
+
+### Code Review
+
+```
+Check @/src/components/Form.jsx and suggest improvements from a performance perspective. Also, if there are any @problems, please suggest how to fix them.
+```
+
+### Debugging Assistance
+
+```
+My npm install failed. Please examine the @terminal output and suggest a solution to the problem.
+```
+
+### Project Analysis
+
+```
+Analyze the code in the @/src/models/ directory and explain the relationships between the data models. Also, tell me how the utility functions in @/src/utils/ are used with these models.
+```
+
+### Code Generation
+
+```
+Create a new Input.tsx component using the same design language as @/src/components/Button.tsx
+```
+
+### Version Control Integration
+
+```
+Review the @git-changes and suggest a commit message for the feature I'm working on.
+```
+
+## Combining Multiple Mentions
+
+You can combine multiple mentions to provide more complex context:
+
+```
+There seems to be a bug in @/src/api/users.js. Please check @problems and @terminal to identify and fix the issue.
+```
+
+## Limitations and Considerations
+
+1. **Large Files**: Referencing very large files may take time to process and could consume a significant amount of tokens.
+
+2. **Binary Files**: Binary files (such as images) will not be properly processed and will show a "Binary file" message.
+
+3. **Directory Structure**: Directory references will only show top-level files and directories, not recursively showing the contents of subdirectories.
+
+4. **URL Limitations**: Some websites may block automated crawling, which could prevent accurate content retrieval.
+
+5. **Path Syntax**: File paths or URLs with special characters (such as spaces) may not be recognized correctly.
+
+## Troubleshooting
+
+### Mentions Not Recognized
+
+If your mentions aren't being recognized correctly, check that:
+
+- There's no space after the `@` symbol
+- File paths are accurate (case-sensitive)
+- URLs include the full format (with `https://`)
+
+### Content Not Retrieved
+
+If the content of referenced resources can't be retrieved:
+
+- Verify the file exists
+- Ensure you have access permissions for the file
+- Check that the file isn't too large or the URL too complex
+
+### Performance Issues
+
+If mention processing is slow:
+
+- Reference smaller files or specific file sections
+- Reduce the number of mentions used at once
+
+## Conclusion
+
+Mastering the mentions feature makes your communication with Cline more efficient. By providing appropriate context, Cline can deliver more accurate assistance, significantly improving your development workflow.
