                }
            }
        },
        {
            "name": "search_documentation",
            "description": "Search technical documentation",
            "parameters": {
                "query": {"description": "Search query", "type": "string"},
                "source": {"description": "Documentation source", "type": "string"}
            }
        }
    ]

# Integration with Foundry Local
async def setup_function_calling():
    tools = define_foundry_tools()
    
    # Configure Foundry Local for function calling
    client = openai.OpenAI(
        base_url=manager.endpoint,
        api_key=manager.api_key
    )
    
    # Use tools in conversation
    response = await client.chat.completions.create(
        model=manager.get_model_info("phi-4-mini").id,
        messages=[
            {"role": "user", "content": "Analyze this Python code for quality issues"}
        ],
        tools=[{"type": "function", "function": tool} for tool in tools],
        tool_choice="auto"
    )
```

```python
class ContextManager:
    """Manages shared context across agents."""
    
    async def share_context(self, agent_id: str, context: dict):
        """Share context with specific agent."""
        
    async def get_shared_memory(self) -> dict:
        """Retrieve shared memory state."""
        
    async def update_global_state(self, updates: dict):
        """Update global orchestrator state."""
```

### 2. 結果綜合
```python
class ResultMerger:
    """Intelligently merge results from multiple agents."""
    
    async def merge_analyses(self, results: list) -> dict:
        """Merge analysis results."""
        
    async def resolve_conflicts(self, conflicting_results: list) -> dict:
        """Resolve conflicting agent outputs."""
        
    async def create_summary(self, all_results: dict) -> str:
        """Create comprehensive summary."""
```

### 3. 質量保證
```python
class QualityController:
    """Ensures output quality and consistency."""
    
    async def validate_output(self, result: dict, criteria: list) -> bool:
        """Validate agent output quality."""
        
    async def cross_check_facts(self, claims: list) -> dict:
        """Cross-verify facts across agents."""
        
    async def ensure_consistency(self, outputs: list) -> dict:
        """Ensure consistent outputs."""
```

## 性能優化

### 1. 模型負載平衡
```python
# Distribute models across agents for optimal resource usage
model_allocation = {
    "code_tasks": "phi-4-mini",
    "research_tasks": "qwen2.5-coder-0.5b", 
    "analysis_tasks": "phi-3.5-mini",
    "general_tasks": "phi-4-mini"
}

orchestrator.configure_model_allocation(model_allocation)
```

### 2. 緩存與內存管理
```python
# Implement intelligent caching
cache_config = {
    "response_cache": True,
    "context_cache": True,
    "tool_result_cache": True,
    "cache_ttl": 3600  # 1 hour
}

orchestrator.configure_caching(cache_config)
```

### 3. 並發執行
```python
# Optimize for parallel processing
concurrency_config = {
    "max_concurrent_agents": 4,
    "agent_pool_size": 8,
    "task_queue_size": 100,
    "timeout_seconds": 300
}

orchestrator.configure_concurrency(concurrency_config)
```
