Tools are always expect to return strings, as they are meant to be used by the agents to generate responses.

There are three ways to create tools for crewAI agents:

• Subclassing BaseTool
• Creating a tool from a function or lambda
• Using the tool decorator

from crewai_tools import BaseTool

class MyCustomTool(BaseTool):
    name: str = "Name of my tool"
    description: str = "Clear description for what this tool is useful for, you agent will need this information to use it."

    def _run(self, argument: str) -> str:
        # Implementation goes here
        pass

Define a new class inheriting from BaseTool, specifying name, description, and the _run method for operational logic.

For a simpler approach, create a Tool object directly with the required attributes and a functional logic.

from crewai_tools import tool
@tool("Name of my tool")
def my_tool(question: str) -> str:
    """Clear description for what this tool is useful for, you agent will need this information to use it."""
    # Function logic here

The tool decorator simplifies the process, transforming functions into tools with minimal overhead.
