### New Tool Request

I cannot complete this task because I need a tool for: {task_description}

**Proposed Implementation:**
Copy
from typing import Any from smolagents.tools import Tool

class NewTool(Tool): name = "[appropriate_name]" description = "{task_description}" inputs = {proposed_inputs} output_type = "{proposed_output}"

def forward(self, [arguments]) -> {proposed_output}:
Copy
{implementation_suggestion}

def __init__(self, *args, **kwargs):
    self.is_initialized = False
Copy

Would you like me to proceed with this implementation? Once implemented, I can complete your requested task.
