## 🧩 Extending the Framework

### Creating Custom Agents

```python
from agents.base_agent import BaseAgent, ProcessingResult

class CustomAgent(BaseAgent):
    def initialize(self) -> bool:
        # Initialize your model here
        self._is_initialized = True
        return True
    
    def process(self, input_data: Any) -> ProcessingResult:
        # Implement your processing logic
        try:
            # Your processing code here
            result_data = {"custom_analysis": "results"}
            
            return ProcessingResult(
                success=True,
                data=result_data,
                confidence=0.95,
                inference_time=50.0
            )
        except Exception as e:
            return ProcessingResult(
                success=False,
                data={},
                error=str(e)
            )
```

## 📊 API Response Format

All endpoints return standardized responses:

```json
{
  "success": true,
  "data": {
    "detections": [...],
    "detection_count": 5,
    "class_summary": {...}
  },
  "inference_time_ms": 45.2,
  "agent_info": {
    "agent_type": "ObjectAgent",
    "device": "cuda",
    "initialized": true
  },
  "timestamp": "2025-08-31T12:00:00.000Z",
  "request_id": "uuid-string"
}
```
