📋 Features

• ✅ 100% Real-time Accuracy: Direct access to VS Code's selected AI model
• 📊 Status Bar Integration: Continuous monitoring with one-click details
• 🤖 Chat Participant: @modeldetector for comprehensive model analysis
• 🌉 MCP Integration: Enhanced capabilities through Model Context Protocol
• 🔗 IPC Bridge: Seamless communication between VS Code and MCP server
• 📈 Detection History: Track model usage patterns over time
• ⚙️ Highly Configurable: Customize monitoring intervals and display options

🏆 Why This Extension?

Perfect Accuracy Through API Breakthrough

// 🎯 The breakthrough: Direct model access
public async detectFromChatContext(request: vscode.ChatRequest): Promise<ModelDetectionResult> {
  const model = request.model; // 100% ACCURATE - Direct VS Code model access
  return { accuracy: 'Perfect', source: 'chat-context', model };
}

Multi-Layer Detection Strategy

1. Chat Context (100% accurate) - Direct request.model access
2. Language Model API (Available models) - vscode.lm.selectChatModels()
3. Storage Cache (Historical) - Previous detection results

🎮 Usage

Chat Participant Commands

@modeldetector                    # Comprehensive model detection
@modeldetector /detect           # Detailed model information  
@modeldetector /monitor          # Enable status bar monitoring

Keyboard Shortcuts

Key Components

ModelDetectorService (Core Breakthrough)

• Primary Method: detectFromChatContext() - 100% accurate via request.model
• Fallback Methods: LM API detection, storage cache
• History Tracking: Complete audit trail of detections

Chat Participant Integration

• Participant: @modeldetector with commands /detect, /monitor
• Real-time Analysis: Instant model information in chat
• Interactive UI: Buttons and follow-up suggestions

Status Bar Manager

• Continuous Display: Real-time model information
• Vendor Icons: Visual identification (🤖 OpenAI, 🔮 Claude, 🧠 Gemini)
• Quick Access: Click for detailed information and controls

🎯 Technical Implementation

Chat Participant API Breakthrough

The key innovation is leveraging VS Code's Chat Participant API:

// Register chat participant with 100% accurate detection
const participant = vscode.chat.createChatParticipant('modeldetector', async (request, context, stream, token) => {
  // 🎯 BREAKTHROUGH: Direct model access
  const model = request.model;
  
  // Perfect accuracy - no file parsing, no guessing
  const modelInfo = {
    id: model.id,
    name: model.name,
    vendor: model.vendor,
    accuracy: 'Perfect',
    source: 'chat-context'
  };
});

Multi-Context Detection Strategy

public async detectCurrentModel(): Promise<ModelDetectionResult> {
  // 1. Try chat context (if available) - 100% accurate
  // 2. Try LM API - available models
  // 3. Use cached result - historical data
  // 4. Graceful error handling
}
