  The pick_random tool handler, which takes a comma-separated string of options and returns a random selection, with basic validation for input length.

  def pick_random(options: str) -> dict:
      """
      Pick a random option from a comma-separated list.
  
      Args:
          options: Comma-separated list of options (e.g., "pizza, burger, sushi")
  
      Returns:
          The randomly selected option
      """
      option_list = [opt.strip() for opt in options.split(",") if opt.strip()]
  
      if len(option_list) < 2:
          return {"error": "Please provide at least 2 comma-separated options"}
  
      if len(option_list) > 100:
          return {"error": "Maximum 100 options allowed"}
  
      choice = random.choice(option_list)
