I have a different approach. Just treat all LLM queries as what they are, instructions to a computer program to generate a desired output. Neither niceties nor insults make a qualitative difference, so you might as well just skip them altogether.

It's a bit as if shell commands added im/politeness arguments that do nothing other than making you feel better about the interaction, like

    git pull --please

or

    ls --forthemillionthtime

I wouldn't use those either.
