  handleResourceRequest(request: MCPResourceRequest): Promise<GeminiResponse>
  handleToolInvocation(tool: MCPTool): Promise<GeminiResult>
  handlePromptExecution(prompt: MCPPrompt): Promise<GeminiCompletion>
  
  // Gemini API Integration
  translateToGeminiRequest(mcpRequest: MCPRequest): GeminiAPIRequest

```

#### 2. Request/Response Translation
```typescript
class ProtocolTranslator {
  // MCP -> Gemini Translation
  translateToolCall(mcpTool: MCPToolCall): GeminiFunction {
    return {
      name: mcpTool.name,
      parameters: this.adaptParameters(mcpTool.arguments),
      execution_context: this.buildGeminiContext(mcpTool.context)
    }

  // Gemini -> MCP Translation
  translateResponse(geminiResult: GeminiResult): MCPResponse {
    return {
      content: geminiResult.candidates[0].content,
      tool_calls: this.adaptToolCalls(geminiResult.function_calls),
      metadata: this.extractMetadata(geminiResult)
    }
  }
}
```

#### 3. Context Window Optimization
```typescript
class ContextManager {
  private contextWindow: ContextWindow
  private cacheManager: ContextCacheManager
  
  optimizeContext(messages: Message[]): OptimizedContext {
    // Leverage Gemini's 1M-2M token window
    const contextSize = this.calculateTokens(messages)
    
    if (contextSize < 1000000) {
      return this.useFullContext(messages)
    }
    
    return this.implementSmartTruncation(messages)
  }
  
  implementContextCaching(context: string): CachedContext {
    // Use Gemini's context caching for 4x cost reduction
    return this.cacheManager.cache(context, {
      ttl: 3600, // 1 hour
      compression: true,
      smart_indexing: true
    })
  }
}
```

## ⚡ BatchTool Parallel Execution Architecture

### Core Execution Engine

#### 1. Parallel Orchestrator
```typescript
class BatchToolOrchestrator {
  private executionGraph: ExecutionGraph
  private resourcePool: ResourcePool
  private coordinationEngine: CoordinationEngine
  
  async executeBatch(operations: Operation[]): Promise<BatchResult> {
    // Build dependency graph
    const graph = this.buildExecutionGraph(operations)
    
    // Identify parallel execution paths
    const parallelGroups = this.identifyParallelGroups(graph)
    
    // Execute with coordination
    return this.executeWithCoordination(parallelGroups)
  }
  
  private async executeWithCoordination(groups: ParallelGroup[]): Promise<BatchResult> {
    const results = await Promise.allSettled(
      groups.map(group => this.executeGroup(group))
    )
    
    return this.consolidateResults(results)
  }
}
```

#### 2. Resource Management
```typescript
class ResourcePool {
  private agentPool: Agent[]
  private memoryPool: MemoryPool
  private computeResources: ComputePool
  
  allocateResources(operation: Operation): ResourceAllocation {
    return {
      agents: this.allocateOptimalAgents(operation),
      memory: this.allocateMemory(operation.memoryRequirements),
      compute: this.allocateCompute(operation.computeRequirements)
    }
  }

    const workers = this.selectWorkers(operations)
    
    return new HierarchicalPlan(coordinator, workers, operations)
  }
}
```

## 🧠 Memory Coordination Patterns

### Distributed Memory Architecture

#### 1. Cross-Agent Memory Sharing
```typescript
class MemoryCoordinator {
  private memoryStore: DistributedMemoryStore
  private conflictResolver: ConflictResolver
  private consistencyManager: ConsistencyManager
  
  async shareMemory(sourceAgent: string, targetAgents: string[], data: MemoryData): Promise<void> {
    // Implement CRDT for conflict-free sharing
    const crdtData = this.toCRDT(data)
    
    await Promise.all(
      targetAgents.map(agent => 
        this.memoryStore.replicate(agent, crdtData)
      )
    )
    
    // Ensure eventual consistency
    await this.consistencyManager.ensureConsistency(targetAgents)
  }
  
  async resolveConflicts(conflicts: MemoryConflict[]): Promise<Resolution[]> {
    return Promise.all(
      conflicts.map(conflict => 
        this.conflictResolver.resolve(conflict)
      )
    )
  }
}
```

#### 2. Intelligent Caching Strategy
```typescript
class SmartCache {
  private cacheStore: CacheStore
  private accessPatterns: AccessPatternAnalyzer
  private evictionPolicy: EvictionPolicy
  
  async cache(key: string, value: any, metadata: CacheMetadata): Promise<void> {
    const score = this.calculateImportanceScore(key, metadata)
    const ttl = this.calculateOptimalTTL(key, this.accessPatterns.analyze(key))
    
    await this.cacheStore.set(key, value, {
      ttl,
      importance: score,
      access_pattern: this.accessPatterns.getPattern(key)
    })
  }
  
  private calculateImportanceScore(key: string, metadata: CacheMetadata): number {
    return (
      metadata.accessFrequency * 0.4 +
      metadata.computationCost * 0.3 +
      metadata.shareability * 0.3
    )
  }
}
```

## 🚀 Performance Optimization Strategies

### 1. Agent Spawn Optimization (<100ms target)

```typescript
class AgentSpawnOptimizer {
  private preWarmPool: PreWarmedAgentPool
  private spawnCache: SpawnCache
  private resourcePredictor: ResourcePredictor
  
  async spawnAgent(type: AgentType, config: AgentConfig): Promise<Agent> {
    const startTime = performance.now()
    
    // Try pre-warmed pool first
    const preWarmed = await this.preWarmPool.getAgent(type)
    if (preWarmed) {
      await preWarmed.configure(config)
      const duration = performance.now() - startTime
      this.recordSpawnTime(duration) // Target: <100ms
      return preWarmed
    }
    
    // Parallel initialization
    const [agent, resources] = await Promise.all([
      this.createAgent(type),
      this.resourcePredictor.predictAndAllocate(type, config)
    ])
    
    await agent.initialize(config, resources)
    
    const duration = performance.now() - startTime
    this.recordSpawnTime(duration)
    
    return agent
  }
}
```

### 2. Context Caching (4x cost reduction)

```typescript
class ContextCacheManager {
  private geminiCache: GeminiContextCache
  private compressionEngine: CompressionEngine
  private cacheHitPredictor: CacheHitPredictor
  
  async cacheContext(context: string, metadata: ContextMetadata): Promise<CacheEntry> {
    // Compress for storage efficiency
    const compressed = await this.compressionEngine.compress(context)
    
    // Predict cache utility
    const utility = this.cacheHitPredictor.predictUtility(context, metadata)
    
    if (utility > 0.7) { // High predicted reuse
      return this.geminiCache.store(compressed, {
        ttl: 3600,
        priority: 'high',
        compression_ratio: compressed.ratio
      })
    }
    
    return this.geminiCache.store(compressed, {
      ttl: 900, // 15 minutes for low utility
      priority: 'low'
    })
  }
}
```

### 1. Native API Integration
```typescript
class GoogleWorkspaceIntegrator {
  private driveAPI: DriveAPI
  private docsAPI: DocsAPI
  private sheetsAPI: SheetsAPI
  private slidesAPI: SlidesAPI
  
  async analyzeDocument(documentId: string): Promise<DocumentAnalysis> {
    const [content, metadata] = await Promise.all([
      this.docsAPI.getContent(documentId),
      this.driveAPI.getMetadata(documentId)
    ])
    
    return this.analyzeWithGemini(content, metadata)
  }
  
  async generatePresentation(data: AnalysisData): Promise<PresentationResult> {
    const slides = await this.generateSlideContent(data)
    const presentation = await this.slidesAPI.create({
      title: data.title,
      slides: slides
    })
    
    return {
      presentationId: presentation.presentationId,
      url: presentation.revisionId,
      slideCount: slides.length
    }
  }
}
```

### 2. Enterprise Security Integration
```typescript
class SecurityManager {
  private iamManager: IAMManager
  private vpcConnector: VPCConnector
  private auditLogger: AuditLogger

    const [permissions, compliance] = await Promise.all([
      this.iamManager.checkPermissions(request.user, request.resource),
      this.checkCompliance(request)
    ])
    
    const result = {
      allowed: permissions.granted && compliance.compliant,
      reason: permissions.reason || compliance.reason,
      auditId: await this.auditLogger.log(request, permissions, compliance)
    }
    
    return result
  }
}
