What do you call a person whose interest might be to discredit your results by trying to find hypothetical mistakes? This person does not seem to focus on solving a problem with pragmatism. Is there a word or an expression for that?

Such an individual could be described as a cynic, or a cynical and captious person.
Caveat: when expressing such an evaluation to royalty, care must be taken, as unforeseen and quite gruesome consequences can result. First, locate your points of egress.

e.g., "My Queen, I find your rejection of my suggestions for a wardrobe makeover utterly cynical and captious! Ah, of course I mean that in the nicest, most flattering way, your Majesty."
