ok so for anyone wandering, most rolls in pf2e are required to be open, except for actions with the secret trait, which the gm rolls in secret. there are very fw of those, and they are only ever used for when a player/pc shouldn't know how well they went. some examples are: peception checks, stealth, recall knowledge, deception, and some other similar checks that, in real life, you couldn't really know how well you did
