Using custom Tool with ConversationalRetrievalChain

[jerpicard]

Hello,

I'm developing a chatbot based on my own data. The chatbot uses gpt-3.5-turbo mode and the chain ConversationalRetrievalChain and ConversationBufferMemory to manage the history. Everything works well.
However, I'm struggling to find the solution out to solve my simple problem : If the user after some exchanges with chatbot enters a polite phrase to thanks the chabot like "Thanks for the information" or "Many thanks!" etc... the Chatbot must reply "It was a pleasure to talk with your, have a nice day!".
I tried to add an instruction in the prompt, it doesn't work well. Also, I wonder if I should use a custom Tool. Unfortunately, I don't know how to do that with the chain ConversationalRetrievalChain.

Any help would be very much appreciated.

Regards,

You dont need an agent tool for this. all you need to modify the prompt. The existing prompt force the chain to only look into the document and if the question is out of document, chain is supposed to not respond. all you have to do is change your prompt.

People are still struggling with it. ConversationalRetrievalChain does not seem to "automagically" perform the tool calling for you.
If you do not use ConversationalRetrievalChain , you can follow https://www.youtube.com/watch?v=a_YC8Ru6Jd0 . But if you do use ConversationalRetrievalChain, you are out of luck it seems. The response will come back empty from the chain.
