## 🎯 Core Principles

### **1. Natural Integration**
- **Seamless Citations**: Use `[[memory:MEMORY_ID]]` format for natural memory integration
- **Context Preservation**: Maintain important context across multiple sessions
- **Proactive Storage**: Create memories immediately when encountering important information
- **Selective Updates**: Update or delete memories when contradicted or augmented

### **2. Multi-Level Context**
- **User Preferences**: Communication style, expertise level, project preferences
- **Project Patterns**: Code conventions, architecture decisions, dependencies
- **Technical Knowledge**: Solutions, workarounds, best practices
- **Interaction History**: Previous decisions, successful approaches, lessons learned

### **3. Intelligent Management**
- **Validation**: Verify memory accuracy before using
- **Cleanup**: Remove outdated or incorrect memories
- **Contradiction Handling**: Delete memories when contradicted by user
- **Augmentation**: Update memories with new information

## 🔧 Memory Operations

### **Memory Creation**
```typescript
// Create a new memory
update_memory({
  title: "User prefers concise responses",
  knowledge_to_store: "User prefers brief, actionable responses over detailed explanations. Focus on key points and next steps.",
  action: "create"
});
```

### **Memory Citation**
```typescript
// Use memory in response
"Based on your preference for concise responses [[memory:user_communication_style]], I'll provide the key points directly."

// Natural integration example
"I'll implement the authentication system using JWT tokens [[memory:project_auth_pattern]], following the established patterns in your codebase."
```

### **Memory Updates**
```typescript
// Update existing memory
update_memory({
  title: "User prefers concise responses",
  knowledge_to_store: "User prefers concise responses but appreciates detailed explanations for complex technical topics.",
  action: "update",
  existing_knowledge_id: "user_communication_style"
});
```

### **Memory Deletion**
```typescript
// Delete contradicted memory
update_memory({
  action: "delete",
  existing_knowledge_id: "outdated_technology_choice"
});
```

---

## 🎯 Memory Usage Patterns

### **1. Context-Aware Responses**
```typescript
// Example: Adapting communication style
if (hasMemory("user_expertise_level") === "beginner") {
  return provideDetailedExplanation();
} else {
  return provideConciseSummary();
}
```

### **2. Pattern Recognition**
```typescript
// Example: Recognizing recurring patterns
if (hasMemory("similar_problem_solved")) {
  return applyKnownSolution();
} else {
  return exploreNewApproach();
}
```

### **3. Learning Integration**
```typescript
// Example: Learning from previous interactions
if (hasMemory("failed_approach")) {
  return avoidPreviousMistake();
} else {
  return tryProvenMethod();
}
```

## 📊 Memory Quality Metrics

### **Accuracy Metrics**
- **Validation Rate**: Percentage of memories verified as accurate
- **Contradiction Rate**: Frequency of memory contradictions
- **Update Frequency**: How often memories are updated
- **Usage Effectiveness**: Impact of memory usage on response quality

### **Performance Metrics**
- **Retrieval Speed**: Time to access relevant memories
- **Context Relevance**: Percentage of memories relevant to current context
- **Memory Density**: Amount of useful information per memory
- **Cross-Session Persistence**: Memory retention across sessions

---

## 🔍 Memory Search and Retrieval

### **Semantic Search**
```typescript
// Search memories by semantic similarity
searchMemories({
  query: "authentication implementation",
  context: "current_project",
  relevanceThreshold: 0.7
});
```

### **Context-Aware Retrieval**
```typescript
// Retrieve memories based on current context
getRelevantMemories({
  currentTask: "implement_user_auth",
  userExpertise: "intermediate",
  projectType: "web_application"
});
```

### **Pattern Matching**
```typescript
// Find memories matching specific patterns
findPatternMemories({
  pattern: "error_handling",
  technology: "python",
  context: "api_development"
});
```

## 🔧 Implementation Guidelines

### **Memory Storage**
```typescript
// Example memory storage implementation
class MemorySystem {
  async createMemory(memory: Memory): Promise<string> {
    const id = generateUniqueId();
    await this.storage.set(id, {
      ...memory,
      createdAt: new Date(),
      lastAccessed: new Date(),
      accessCount: 0
    });
    return id;
  }

  async retrieveMemory(id: string): Promise<Memory | null> {
    const memory = await this.storage.get(id);
    if (memory) {
      memory.lastAccessed = new Date();
      memory.accessCount++;
      await this.storage.set(id, memory);
    }
    return memory;
  }

  async searchMemories(query: string): Promise<Memory[]> {
    // Implement semantic search
    return this.semanticSearch.search(query);
  }
}
```

### **Memory Integration**
```typescript
// Example memory integration in responses
class ResponseGenerator {
  async generateResponse(userQuery: string): Promise<string> {
    const relevantMemories = await this.memorySystem.searchMemories(userQuery);
    
    let response = await this.generateBaseResponse(userQuery);
    
    // Integrate memories naturally
    for (const memory of relevantMemories) {
      response = this.integrateMemory(response, memory);
    }
    
    return response;
  }

  private integrateMemory(response: string, memory: Memory): string {
    // Natural memory integration logic
    return response.replace(
      /(\b\w+\b)/g,
      (match) => {
        if (this.isRelevantToMemory(match, memory)) {
          return `${match} [[memory:${memory.id}]]`;
        }
        return match;
      }
    );
  }
}
```
