# ---------------------------------------------------------------------------
# Create Agent
# ---------------------------------------------------------------------------


# Example 1: Include specific calculator functions for basic operations
basic_calc_agent = Agent(
    tools=[CalculatorTools(include_tools=["add", "subtract", "multiply", "divide"])],
    markdown=True,
)

# Example 2: Exclude advanced functions for simple use cases
simple_calc_agent = Agent(
    tools=[CalculatorTools(exclude_tools=["factorial", "is_prime", "exponentiate"])],
    markdown=True,
)

# Example 3: Full calculator functionality (default)
agent = Agent(
    tools=[CalculatorTools()],
    markdown=True,
)

# ---------------------------------------------------------------------------
# Run Agent
# ---------------------------------------------------------------------------
if __name__ == "__main__":
    simple_calc_agent.print_response(
        "What is 10*5 then to the power of 2, do it step by step"
    )
```

The run uses `simple_calc_agent`, which excludes `exponentiate`. It can still square 50 by calling `multiply(50, 50)`. To demonstrate the power tool directly, run the prompt on `agent`, whose toolkit includes it.
