fix: tool calling cohere

[Anirudh31415926535]

Why are these changes needed?

The tool calling in the current integration with Cohere has some subtle fallacies in them. These changes ensure that the tool calling happens in the apt mechanism for the Cohere models.

Checks

• I've included any doc changes needed for https://microsoft.github.io/autogen/. See https://microsoft.github.io/autogen/docs/Contribute#documentation to build and test documentation locally.
• I've added tests (if relevant) corresponding to the changes introduced in this PR.
• I've made sure all auto checks have passed.

Hi @Anirudh31415926535, thanks for your contribution - can you provide a code example that isn't working with the current code so we can test it?

Hi @marklysze Thanks for looking through! I think its not so much that an example doesn't work because it throws an error...
Without these changes, the raw prompts that the Cohere model views is somewhat incomplete, which may impact performance.
Hope that clarifies! :)

Hey @Anirudh31415926535, thanks for the note - I'll give it a test. Would you be able to provide a little bit of a summary as to what may have been incomplete?

Hey @Anirudh31415926535, thanks for the note - I'll give it a test. Would you be able to provide a little bit of a summary as to what may have been incomplete?

Well, the basic idea is that from our api, we parse the different bits of the request body and have it formatted into a raw prompt that is seen by the model. Since the autogen integration was missing some parameters, it results in an incorrect/incomplete raw prompt being generated which is sent to our model, which might cause some regressions.

An example of this is that we need the tool_calls field in the chat history Chatbot messages, that is parsed and contributes to a section of the raw prompt that enabels the model to know that so and so tool call was performed as part of this conversation so that it can continue to hold context of it. If this were absent, then it would lead to that part of the raw prompt being empty, which would be unfortunate.
So, you wouldn't necessarily get an error, but since the raw prompts would be inaccurate, there might be some performance regressions.

Similarly, for the other changes added too! Hope that is a clearer picture of what I was referring to!

That's a great explanation and definitely a worthy change to incorporate :)

Thanks for coming and helping align AutoGen's client class with your API.

[marklysze]

@Anirudh31415926535, is it possible to move the code for the client_name down to the create function and use the params parameter which will have it. The reason is the init function only includes kwargs that align with OpenAI, so although it's in our config it won't come into the init. It will be passed into the create function.

It would also be good to update the documentation, I think just the "API parameters" section is okay:

Done! Just pushed the fixes!

@Anirudh31415926535 has been great in making all the adjustments - changes look good to go. Happy to merge!

@thinkall is that something you can help with?
