Coworkers not specified with last commits

Issue Summary

Yesterday's commits (7fd8850) changed the declaration of delegate or ask_coworker functions, leading to prompts like this:

Ask question to co-worker: Ask question to co-worker(question: str, context: str, coworker: Optional[str] = None, **kwargs) - Ask a specific question to one of the following co-workers: [xxx,yyy,zzz]

I believe that due to coworker: Optional[str] = None, the response of LLM now lacks the "coworker" parameter.

Steps to Reproduce

1. Action: Ask question to co-worker
2. Action Input:

   {
       "question": "Can you provide me with the DNS hosts that the domain 'xxx.com' is delegated to?",
       "context": "The client is inquiring about the DNS hosts that the domain 'xxx.com' is delegated to. They are requesting this information."
   }

Expected Result

The "coworker" parameter should be included in the Action Input.

Actual Result

The "coworker" parameter is missing, which ends with an error:

Error executing tool. Co-worker mentioned not found, it must be one of the following options: [xxx,yyy,zzz]
