Hey Felix Buschkotte, I didn't want to re-run any columns to not affect your flow but tried to check out a few other examples some people have and how they're setting up their prompts. What I think would help improve this a bit, is to tell it what things you consider part of categorization or maybe an example of that could help.
To be a bit more specific, you can also tell it to only evaluate the product or service description it finds besides the above. I think those detailed guardrails will make it more consistent or accurate
