Unable to use tools

[CommanderLake]

I see that GGUF files have a Jinja prompt template which builds a prompt listing any tools i add upon applying a template and i've been trying to get tools capable models like QwQ and Qwen3 to use a tool which i have configured but it never uses the tool and is unaware of the tool even when i tell it about the tool, is there something i have to call to get it to build the prompt for tool use?

You can see my code in this repo: https://github.com/CommanderLake/LMStud
Specifically stud.cpp in the Stud project folder.

Thanks for any help :)

Turns out i just had to enable Jinja when loading the model and ensure there are no blank messages.
