    The reply function will be called when the trigger matches the sender.
    The function registered later will be checked earlier by default.
    To change the order, set the position to a positive integer.

    Both sync and async reply functions can be registered. The sync reply function will be triggered
    from both sync and async chats. However, an async reply function will only be triggered from async
    chats (initiated with `ConversableAgent.a_initiate_chat`). If an `async` reply function is registered
    and a chat is initialized with a sync function, `ignore_async_in_sync_chat` determines the behaviour as follows:
        if `ignore_async_in_sync_chat` is set to `False` (default value), an exception will be raised, and
        if `ignore_async_in_sync_chat` is set to `True`, the reply function will be ignored.

    Args:
        trigger (Agent class, str, Agent instance, callable, or list): the trigger.
            If a class is provided, the reply function will be called when the sender is an instance of the class.
            If a string is provided, the reply function will be called when the sender's name matches the string.
            If an agent instance is provided, the reply function will be called when the sender is the agent instance.
            If a callable is provided, the reply function will be called when the callable returns True.
            If a list is provided, the reply function will be called when any of the triggers in the list is activated.
            If None is provided, the reply function will be called only when the sender is None.
            Note: Be sure to register `None` as a trigger if you would like to trigger an auto-reply function with non-empty messages and `sender=None`.
        reply_func (Callable): the reply function.
            The function takes a recipient agent, a list of messages, a sender agent and a config as input and returns a reply message.

            ```python
            def reply_func(

        position (int): the position of the reply function in the reply function list.
            The function registered later will be checked earlier by default.

        config (Any): the config to be passed to the reply function.
            When an agent is reset, the config will be reset to the original value.
        reset_config (Callable): the function to reset the config.
            The function returns None. Signature: ```def reset_config(config: Any)```
        ignore_async_in_sync_chat (bool): whether to ignore the async reply function in sync chats. If `False`, an exception
            will be raised if an async reply function is registered and a chat is initialized with a sync

                return recipient.last_message(sender)["content"]
            ```
        summary_args (dict): a dictionary of arguments to be passed to the summary_method.
            One example key is "summary_prompt", and value is a string of text used to prompt a LLM-based agent (the sender or recipient agent) to reflect
            on the conversation and extract a summary when summary_method is "reflection_with_llm".
            The default summary_prompt is DEFAULT_SUMMARY_PROMPT, i.e., "Summarize takeaway from the conversation. Do not add any introductory phrases. If the intended request is NOT properly addressed, please point it out."
            Another available key is "summary_role", which is the role of the message sent to the agent in charge of summarizing. Default is "system".
        message (str, dict or Callable): the initial message to be sent to the recipient. Needs to be provided. Otherwise, input() will be called to get the initial message.
            - If a string or a dict is provided, it will be used as the initial message.        `generate_init_message` is called to generate the initial message for the agent based on this string and the context.
                If dict, it may contain the following reserved fields (either content or tool_calls need to be provided).

                    1. "content": content of the message, can be None.
                    2. "function_call": a dictionary containing the function name and arguments. (deprecated in favor of "tool_calls")
                    3. "tool_calls": a list of dictionaries containing the function name and arguments.
                    4. "role": role of the message, can be "assistant", "user", "function".
                        This field is only needed to distinguish between "function" or "assistant"/"user".
                    5. "name": In most cases, this field is not needed. When the role is "function", this field is needed to indicate the function name.
                    6. "context" (dict): the context of the message, which will be passed to
                        `OpenAIWrapper.create`.

            - If a callable is provided, it will be called to get the initial message in the form of a string or a dict.
                If the returned type is dict, it may contain the reserved fields mentioned above.

                Example of a callable message (returning a string):

                ```python
                def my_message(
                    sender: ConversableAgent, recipient: ConversableAgent, context: dict
                ) -> Union[str, Dict]:
                    carryover = context.get("carryover", "")
                    if isinstance(message, list):
                        carryover = carryover[-1]
                    final_msg = "Write a blogpost." + "\\nContext: \\n" + carryover
                    return final_msg
                ```

                Example of a callable message (returning a dict):

                ```python
                def my_message(
                    sender: ConversableAgent, recipient: ConversableAgent, context: dict
                ) -> Union[str, Dict]:
                    final_msg = {}
                    carryover = context.get("carryover", "")
                    if isinstance(message, list):
                        carryover = carryover[-1]
                    final_msg["content"] = "Write a blogpost." + "\\nContext: \\n" + carryover
                    final_msg["context"] = {"prefix": "Today I feel"}
                    return final_msg
                ```
        **kwargs: any additional information. It has the following reserved fields:
            - "carryover": a string or a list of string to specify the carryover information to be passed to this chat.
                If provided, we will combine this carryover (by attaching a "context: " string and the carryover content after the message content) with the "message" content when generating the initial chat
                message in `generate_init_message`.
            - "verbose": a boolean to specify whether to print the message and carryover in a chat. Default is False.

    Raises:
        RuntimeError: if any async reply functions are registered and not ignored in sync chat.

    Returns:
        ChatResult: an ChatResult object.
