Environment Setup

Set at least one LLM provider:

export ANTHROPIC_API_KEY=your-key  # For Claude
export OPENAI_API_KEY=your-key     # For GPT
export HANZO_API_KEY=your-key      # For Hanzo AI

Advanced Features

Voice Mode

Install voice dependencies:

pip install hanzo-dev[voice]

Enable in REPL:

>>> enable_voice()
>>> chat("Hello")  # Speak your message

Custom Tools

Create custom tools on the fly:

@register_tool
def my_tool(param: str) -> str:
    """My custom tool."""
    return f"Processed: {param}"

# Now available to AI
>>> chat("Use my_tool to process 'hello'")

Scripting

Use the REPL in scripts:

from hanzo_dev import create_repl

async def main():
    repl = create_repl()
    result = await repl.chat("Analyze the project structure")
    print(result)

Integration with Hanzo Ecosystem

With Hanzo MCP

All MCP tools are automatically available:

• File operations
• Code search and analysis
• Process management
• Git operations
• And 60+ more tools

With Hanzo Agents

Create and manage agents:

>>> agent = create_agent("researcher")
>>> agent.run("Research best practices for API design")

With Hanzo Network

Dispatch to agent networks:

>>> network.dispatch("Solve this problem", agents=5)

Tips

1. Tab Completion: Use Tab to explore available tools and parameters
2. Help System: Use ? after any function for documentation
3. History: Use up/down arrows to navigate command history
4. Shortcuts: Ctrl+R for reverse search, Ctrl+L to clear screen
5. Output: Results are automatically pretty-printed with Rich

Troubleshooting

No LLM Response

Ensure you have set API keys:

echo $ANTHROPIC_API_KEY  # Should show your key

Tool Errors

Check tool permissions:

>>> mcp.get_allowed_paths()
>>> mcp.add_allowed_path("/path/to/allow")

Performance

For better performance:

>>> set_model("gpt-3.5-turbo")  # Faster model
>>> set_streaming(True)  # Stream responses
