That’s still only as good as the ability of the trusted model to delineate instructions from data. The untrusted model will inevitably be compromised so as to pass bad data to the trusted model.

I have significant doubt that a P-LLM (as in the camel paper) operating a programming-language-like instruction set with “really good checks” is sufficient to avoid this issue. If it were, the P-LLM could be replaced with a deterministic tool call.
