To me, it seems each of these is requiring a certain degree of detail in player specificstion of approach and aptitude of the player in the skill naming specific tells in advance, knowing specific tricks to surprise reactions etc" and also even a very specific focus- not just deception but pre-choosing deception about what. Wrong guess on what he is gonna be hiding and what then? Wasted effort and time?
I don't know what happens. It depends on the specific circumstances that are occurring in the game which I don't even come close to having here. At worst, we have some really good roleplaying.
When I compare that to the repeated claims about how nope, player just gives me something of an approach, not requiring player side knowledge etc... and I look at other skills like say arcana, medicine, survival for say foraging or spotting tracks etc or even stealth- it's hard to believe that those skills also require that much "player aptitude in how done."
Then don't get that detailed. You can just tell me that you examine the object to see if you can figure out if it has arcane worth. Don't expect an auto success or even a bonus, though. Don't expect a penalty, either. If you are going to be basic in my game, you are just going to get basic chances. You only need to be as detailed as you want to be.
