        ),
    )
)

Complete error:

Value error, Invalid tool type: <class ‘tuple’>. Tool must be an instance of BaseTool or an object with ‘name’, ‘func’, and ‘description’ attributes. [type=value_error, input_value=CSVSearchTool(name='CSVSe… ‘retrival_document’}}}), input_type=CSVSearchTool]

@Aditya_Agarwal : I too faced similar issue, I have tried to define the customtool by having BaseTool Inherited

Like this one

from crewai.tools import BaseTool
from langchain_community.agent_toolkits.file_management.toolkit import FileManagementToolkit

class LangFileManagementTools(BaseTool):
name: str = “CustomReadFileTool”
description: str = “Useful for search-based queries. Use this to find current information about markets, companies, and trends.”

def _run(self) -> [BaseTool]:
    """
    
    :return:
    """
    return FileManagementToolkit(root_dir='workdir',  selected_tools=["read_file", "list_directory"]).get_tools()

It is like a customTool but it didn’t work properly
