## Choosing the Right Swarm Architecture

### Decision Framework

Use this framework to select the optimal swarm architecture for your use case:

1. **Task Complexity Analysis**
    - Simple tasks → `AutoSwarmBuilder`
    
    - Complex tasks → `HiearchicalSwarm` or `MultiAgentRouter`
    
    - Dynamic tasks → `AgentRearrange`

2. **Workflow Pattern**
    
    - Linear processes → `SequentialWorkflow`
    
    - Parallel operations → `ConcurrentWorkflow`
    
    - Collaborative tasks → `GroupChat`

3. **Domain Requirements**
    
    - Multi-domain expertise → `MixtureOfAgents`
    
    - Data processing → `SpreadSheetSwarm`
    
    - Quality assurance → `MajorityVoting`

## Production Implementation Guide

### Authentication Best Practices

```python
import os
from dotenv import load_dotenv

# Load environment variables
load_dotenv()

# Secure API key management
API_KEY = os.getenv("SWARMS_API_KEY")
if not API_KEY:
    raise EnvironmentError("API key not found")

# Headers with retry capability
headers = {
    "x-api-key": API_KEY,
    "Content-Type": "application/json",
}
```

### Robust Error Handling

```python
import backoff
import requests
from typing import Dict, Any

class SwarmsAPIError(Exception):
    """Custom exception for Swarms API errors"""
    pass

@backoff.on_exception(
    backoff.expo,
    (requests.exceptions.RequestException, SwarmsAPIError),
    max_tries=5
)
def execute_swarm(payload: Dict[str, Any]) -> Dict[str, Any]:
    """
    Execute swarm with robust error handling and retries
    """
    try:
        response = requests.post(
            f"{BASE_URL}/v1/swarm/completions",
            headers=headers,
            json=payload,
            timeout=30
        )
        
        response.raise_for_status()
        return response.json()
        
    except requests.exceptions.RequestException as e:
        if e.response is not None:
            if e.response.status_code == 429:
                # Rate limit exceeded
                raise SwarmsAPIError("Rate limit exceeded")
            elif e.response.status_code == 401:
                # Authentication error
                raise SwarmsAPIError("Invalid API key")
        raise SwarmsAPIError(f"API request failed: {str(e)}")
```
