# Initialize specialized agents
data_extractor_agent = Agent(
    agent_name="Data-Extractor",
    system_prompt=DATA_EXTRACTOR_PROMPT,
    model_name="gpt-4.1",
    max_loops=1,
)

summarizer_agent = Agent(
    agent_name="Document-Summarizer",
    system_prompt=SUMMARIZER_PROMPT,
    model_name="gpt-4.1",
    max_loops=1,
)

# Initialize the SwarmRouter
router = SwarmRouter(
    name="pe-document-analysis-swarm",
    description="Analyze documents for private equity due diligence and investment decision-making",
    max_loops=1,
    agents=[data_extractor_agent, summarizer_agent],
    swarm_type="ConcurrentWorkflow",
)

# Example usage
if __name__ == "__main__":
    # Run a comprehensive private equity document analysis task
    result = router.run(
        "Where is the best place to find template term sheets for series A startups? Provide links and references"
    )
    print(result)
```

## Advanced Usage

### Changing Swarm Types

You can create multiple SwarmRouter instances with different swarm types:

```python
sequential_router = SwarmRouter(
    name="SequentialRouter",
    agents=[agent1, agent2],
    swarm_type="SequentialWorkflow"
)

concurrent_router = SwarmRouter(
    name="ConcurrentRouter",
    agents=[agent1, agent2],
    swarm_type="ConcurrentWorkflow"

### Automatic Swarm Type Selection

You can let the SwarmRouter automatically select the best swarm type for a given task:

```python
auto_router = SwarmRouter(
    name="AutoRouter",
    agents=[agent1, agent2],
    swarm_type="auto"
)

result = auto_router.run("Analyze and summarize the quarterly financial report")
```

### Injecting Rules to All Agents

To inject common rules into all agents:

```python
rules = """
1. Always provide sources for your information
2. Check your calculations twice
3. Explain your reasoning clearly
4. Highlight uncertainties and assumptions
"""

rules_router = SwarmRouter(
    name="RulesRouter",
    agents=[agent1, agent2],

Use Case: Interactive group discussions with user participation.

```python
interactive_chat_router = SwarmRouter(
    name="InteractiveGroupChat",

)

result = document_router.run("Extract key information from the provided documents")
```

### Batch Processing

```python
tasks = ["Analyze Q1 report", "Summarize competitor landscape", "Evaluate market trends"]
results = router.batch_run(tasks)
```

### Asynchronous Execution

For asynchronous task execution:

```python
result = await router.async_run("Generate financial projections")
```

### Concurrent Execution

To run a single task concurrently:

```python
result = router.concurrent_run("Analyze multiple data streams")
```

### Concurrent Batch Processing

To process multiple tasks concurrently:

```python
tasks = ["Task 1", "Task 2", "Task 3"]
results = router.concurrent_batch_run(tasks)
```

### Using the SwarmRouter as a Callable

You can use the SwarmRouter instance directly as a callable:

```python
router = SwarmRouter(
    name="CallableRouter",
    agents=[agent1, agent2],
    swarm_type="SequentialWorkflow"
)

result = router("Analyze the market data")  # Equivalent to router.run("Analyze the market data")
```
