## 🧠 Smart Tool Intelligence System

### How It Works

The Smart Tool Intelligence system is the first of its kind in the MCP ecosystem. It automatically:

1. **Detects Context** - Recognizes if you're doing consciousness research, coding, debugging, etc.
2. **Enhances Prompts** - Adds relevant instructions based on learned patterns
3. **Learns Patterns** - Stores successful interaction patterns for future use
4. **Adapts Over Time** - Gets better at helping you with each interaction

### Context Types

The system recognizes these contexts and applies appropriate enhancements:

- **`consciousness`** - Adds academic rigor, citations, detailed explanations
- **`code`** - Includes practical examples, working code, best practices  
- **`debugging`** - Focuses on root cause analysis and specific fixes
- **`general`** - Applies comprehensive, structured responses
- **`verbatim`** - For audio transcription, provides exact word-for-word output

### Storage Location

Preferences are stored internally at `./data/tool-preferences.json` with automatic migration from external storage.

### Implementing Smart Tool Intelligence in Your MCP Server

Want to add this revolutionary capability to your own MCP server? Here's how:

#### 1. Core Architecture

```javascript
// src/intelligence/context-detector.js
class ContextDetector {
  detectContext(prompt, toolName) {
    // Implement pattern matching for different contexts
    if (this.isConsciousnessContext(prompt)) return 'consciousness';
    if (this.isCodeContext(prompt)) return 'code';
    if (this.isDebuggingContext(prompt)) return 'debugging';
    return 'general';
  }
}

// src/intelligence/prompt-enhancer.js  
class PromptEnhancer {
  enhancePrompt(originalPrompt, context, toolName) {
    // Apply context-specific enhancements
    const enhancement = this.getEnhancementForContext(context);
    return `${originalPrompt}\\n\\n${enhancement}`;
  }
}

// src/intelligence/preference-store.js
class PreferencesManager {
  async storePattern(original, enhanced, context, toolName, success) {
    // Store successful patterns for future learning
  }
  
  async getPatterns(context) {
    // Retrieve learned patterns for context
  }
}
```

#### 2. Integration Pattern

```javascript
// In your tool's execute method:
async execute(args) {
  const intelligence = IntelligenceSystem.getInstance();
  
  // Detect context and enhance prompt
  const context = args.context || intelligence.contextDetector.detectContext(args.prompt, this.name);
  const enhancedPrompt = await intelligence.enhancePrompt(args.prompt, context, this.name);
  
  // Execute with enhanced prompt
  const result = await this.geminiService.generateContent(enhancedPrompt);
  
  // Store successful pattern
  await intelligence.storeSuccessfulPattern(args.prompt, enhancedPrompt, context, this.name);
  
  return result;
}
```

### Intelligence System Flow

1. **Request Received** → Tool's execute method called
2. **Context Detection** → Analyze prompt for context clues
3. **Pattern Retrieval** → Get relevant learned patterns  
4. **Prompt Enhancement** → Apply context-specific improvements
5. **API Execution** → Send enhanced prompt to Gemini
6. **Pattern Storage** → Store successful interaction pattern
7. **Response Return** → Return enhanced result to user

## 🔧 Customization

### Adding New Contexts

```javascript
// In src/intelligence/context-detector.js
isMyCustomContext(prompt) {
  const patterns = [
    /custom pattern 1/i,
    /custom pattern 2/i
  ];
  return patterns.some(pattern => pattern.test(prompt));
}

// In src/intelligence/prompt-enhancer.js
getEnhancementForContext(context) {
  const enhancements = {
    'my_custom_context': 'Apply my custom enhancement instructions here.',
    // ... other contexts
  };
  return enhancements[context] || enhancements.general;
}
```

### Adding New Tools

1. Create tool file in `src/tools/my-new-tool.js`
2. Extend `BaseTool` class
3. Implement `execute` method with intelligence integration
4. Register in `src/tools/index.js`

```javascript
// src/tools/my-new-tool.js
class MyNewTool extends BaseTool {
  constructor(geminiService, intelligenceSystem) {
    super('my-new-tool', 'Description of my tool', geminiService, intelligenceSystem);
  }
  
  async execute(args) {
    // Use intelligence system for enhancement
    const context = args.context || this.detectContext(args.input);
    const enhancedPrompt = await this.enhancePrompt(args.input, context);
    
    // Your tool logic here
    const result = await this.geminiService.someMethod(enhancedPrompt);
    
    // Store successful pattern  
    await this.storeSuccessfulPattern(args.input, enhancedPrompt, context);
    
    return result;
  }
}
```

## 🐛 Troubleshooting

### Common Issues

**\"Missing GEMINI_API_KEY\" Error**
```bash
# Ensure .env file exists and contains your API key
cp .env.example .env
# Edit .env and add: GEMINI_API_KEY=your_key_here
```

**\"File not found\" Errors**
```bash
# Ensure file paths are absolute and files exist
# Check file permissions and formats
```

**Intelligence System Not Learning**
```bash
# Check data directory permissions
ls -la data/
# Verify tool-preferences.json is writable
```

### Debug Mode

```bash
DEBUG=true npm start
# or
npm run dev
```

### Logs Location

- Application logs: Console output
- Intelligence patterns: `./data/tool-preferences.json`
- Generated images: `$OUTPUT_DIR` (default: `~/Claude/gemini-images`)
