Devstral 2 small Jinja template error

[imqqmi]

I've used the template below (cut off the instructions). When the tool triggers, the LM studio jinja template gets corrupted. See LM studio error message at the bottom. I suspect the SKILLS.md text isn't properly escaped when feeding it into the LLM.

LM studio error:

This is usually an issue with the model's prompt template. If you are using a popular model, you can try to search the model under lmstudio-community, which will have fixed prompt templates. If you cannot find one, you are welcome to post this issue to our discord or issue tracker on GitHub. Alternatively, if you know how to write jinja templates, you can override the prompt template in My Models > model settings > Prompt Template.
