Sorry did not had much time to look at this lately, I will try to review tomorrow

https://platform.openai.com/docs/guides/function-calling hmm so i went through this but it looks the wawy you are handling tool calls here is very different from the official documentation, does the tool calling part work?

[rakotomandimby]

@deathbeam ,

My knowledge was :

• https://platform.openai.com/docs/guides/tools
• https://platform.openai.com/docs/guides/migrate-to-responses#7-upgrade-to-native-tools (then select "bash" to see the raw API call)

I am sorry to see they have documentation divergence...

[rakotomandimby]

@deathbeam , I pushed a fix for tool calling. You were right there were a problem. I think it is good now. Feel free to review and comment.
