The TypeError you're encountering is likely due to the BaseTool.__call__() method not expecting the directory keyword argument. This can happen if the method signature does not include directory as a parameter, or if the tool is not set up to handle this argument.

In LangChain, tools can be defined with specific parameters using the @tool decorator and an args_schema to validate and specify expected parameters. If directory is not part of this schema or the method signature, it will result in an unexpected keyword argument error.

To resolve this, ensure that the execute_command function is correctly defined with the directory parameter in its schema. You might need to update the tool's definition to include directory as an expected argument. Here's a brief example of how you might define such a tool:

from pydantic import BaseModel, Field
from langchain_core.tools import tool

class CommandInput(BaseModel):
    command: str = Field(description="The command to execute")
    directory: str = Field(default="", description="The directory to execute the command in")

@tool("command-execution-tool", args_schema=CommandInput)
def execute_command(command: str, directory: str = "") -> str:
    # Your command execution logic here
    pass

Make sure that the args_schema includes all the parameters you intend to use, and that they match the function signature. This should help in resolving the TypeError related to unexpected keyword arguments.
