[Issue]: chat_messages usage in 2 agents with tools about autogen HOT 3 OPEN

hi @kk2491, thank you for your kind words, i think this tutorial should help you in resuming the groupchat. https://microsoft.github.io/autogen/docs/topics/groupchat/resuming_groupchat/

from autogen.

@Hk669 Thank you for providing the relevant material. I have gone through the details.
In my case, I am looking for a chat between only 2 agents and how can I effectively use chat_messages field in the ConversableAgent to add the previous chat history.

Thank you,
KK

I believe this is the key for you:

chat_result = user_proxy.initiate_chat(
            assistant,
            message=question,
        )

in a new chat, normally, you pass in a message which is a string, and the initiate_chat does the rest... if you look at that function, you'll see summary discussed and carryover/context but not how to add chat_history.
You can pass a set of chat messages, with your question last, but look at your example.. the last two items:

{'content': '', 'role': 'assistant'}, 
{'content': 'TERMINATE', 'role': 'user'}

Probably don't want to pass those in...

BUT the /agentchat/chat.py does contain a function: initiate_chats() which includes args for:

 - `"carryover"` - It can be used to specify the carryover information to be passed
               to this chat. If provided, we will combine this carryover with the "message" content when
               generating the initial chat message in `generate_init_message`.
- `"finished_chat_indexes_to_exclude_from_carryover"` - It can be used by specifying a list of indexes of the finished_chats list, from which to exclude the summaries for carryover. If 'finished_chat_indexes_to_exclude_from_carryover' is not provided or an empty list, then summary from all the finished chats will be taken.

if you are doing summaries, this is helpful, less tokens to send/process.
But this can be used to 'cleanup' the chat_history (+ current message) and give you a single 'message bundle' to send to initiate a new chat, with the history of previous discussions
