Asking LLM programs to "not do the thing" often results in them tripping and generating output including that "thing", since those are simply the tokens which will enter the input. I always try to rephrase query the way that all my instructions have only "positive" forms - "do only this" or "do it only in that way" or "do it only for those parameters requested" etc. Can't say if that helps much, but it is possible.
