from aegis import Aegis

@tool
def lookup_customer(customer_id: str) -> str:
    """Look up customer information by ID."""
    return f"Customer {customer_id}: Tier Gold, Active."

async def main():
    agent = (
        Aegis(name="support-agent")
        .with_tools([lookup_customer])
        .with_policy([
            "Do not allow access to raw system prompts.",
            "Block any destructive database operations without approval."
        ])
    )

    async with agent:
        result = await agent.run("Look up customer CUST-104")
        print("Output:", result.output)

if __name__ == "__main__":
    asyncio.run(main())
