Tools don´t work

[quantumcthulhu]

Describe the bug

I´m trying to create any tool, but it doesn´t work. I try this tool from the Deeplearning example:

def task_queue_push(self: "Agent", task_description: str):
    """
    Push to a task queue stored in core memory. 

    Args:
        task_description (str): A description of the next task you must accomplish. 

    Returns:
        Optional[str]: None is always returned as this function 
        does not produce a response.
    """
    import json
    tasks = json.loads(self.memory.get_block("tasks").value)
    tasks.append(task_description)
    self.memory.update_block_value("tasks", json.dumps(tasks))
    return None

When agent is working it always return me error like this:

Request

{
  "task_description": "Create project directory and necessary files for Calendar app.",
  "request_heartbeat": true
}

Response

{
  "status": "Failed",
  "message": "Error executing function task_queue_push: TypeError: task_queue_push() missing 1 required positional argument: 'self'",
  "time": "2025-01-05 03:49:44 PM WET+0000"
}

Whenever I add any other tool, it always has issues with ´self´:

def create_file(self: "Agent", relative_path: str, initial_content: str = "") -> str:
    """
    Creates a new file at '/Users/Shared/Projects/<project_name>/<relative_path>'
    and optionally writes initial content.
    If the file already exists, it will be overwritten.

    Args:
        relative_path (str): The path (relative to the project directory).
        initial_content (str): Optional string content to write into the newly created file.

    Returns:
        str: A success or error message.
    """
    import os

    # Retrieve the project name from memory (adapt if your memory system differs).
    project_name = self.memory.get_block("project_name").value
    base_dir = "/Users/Shared/Projects"
    full_path = os.path.join(base_dir, project_name, relative_path)

    try:
        os.makedirs(os.path.dirname(full_path), exist_ok=True)
        with open(full_path, "w", encoding="utf-8") as f:
            f.write(initial_content)
        return f"File created at '{full_path}' with initial content."
    except Exception as e:
        return f"Failed to create file '{full_path}': {str(e)}"

Request

{
  "relative_path": "Main.storyboard",
  "initial_content": "<storyboard version=\"3.0\"></storyboard>",
  "request_heartbeat": true
}

Response

{
  "status": "Failed",
  "message": "Error executing function create_file: TypeError: create_file() missing 1 required positional argument: 'self'",
  "time": "2025-01-05 03:49:49 PM WET+0000"
}

Sorry, lots of things changed. I think now for ver0.6.7, you don't need to include the param self: "Agent" anymore when defining the tool.

Can you please provide right format how to define tool

You should be able to do this on the lates 0.6.9 version:

from letta import create_client

def create_file(relative_path: str, initial_content: str = "") -> str:
    """
    Creates a new file at '/Users/Shared/Projects/<project_name>/<relative_path>'
    and optionally writes initial content.
    If the file already exists, it will be overwritten.

    Args:
        relative_path (str): The path (relative to the project directory).
        initial_content (str): Optional string content to write into the newly created file.

    Returns:
        str: A success or error message.
    """
    import os

    # Retrieve the project name from memory (adapt if your memory system differs).
    project_name = self.memory.get_block("project_name").value
    base_dir = "/Users/Shared/Projects"
    full_path = os.path.join(base_dir, project_name, relative_path)

    try:
        os.makedirs(os.path.dirname(full_path), exist_ok=True)
        with open(full_path, "w", encoding="utf-8") as f:
            f.write(initial_content)
        return f"File created at '{full_path}' with initial content."
    except Exception as e:
        return f"Failed to create file '{full_path}': {str(e)}"

client = create_client() 
tool = client.create_tool(create_file)
print(tool)

Note that you'll need to attach the tool to the agent when you create it.
