I would tend to agree. The first trapped chest I ran into I expected to be trapped. When I had no options to investigate it I shrugged and unlocked it. Unlocking it triggered a check which I passed revealing the trap. I was like, cool, and clicked on it with the expectation to get a disarm, nope, blew up. Bit of a trek back after "quick" loading to try again. This time I unlocked it, made the check again and checked again seeing disarm as an option. So I disarmed it and was good to go. There was no real explanation. Also, you have a moment to notice the thing the character noticed sometimes. Once I found a pouch, but I hadn't been looking at the screen in that spot when it happened so when I looked I couldn't figure out what it was that they'd found. I tried checking the log, but there was nothing in there.
The problem is, I get the feeling they're not passive checks. I'm pretty sure they're active checks happening in locations where it would be relevant to have them. The problem is that if you fail them you just fail them and that's it. Even though these are checks that should be able to be redone, if you fail it's just over. I'm also hoping that in the future there will be information in the log, like, "Oh look a pouch on the ground." "Hey this chest is trapped." It would also be nice if lockpick/disarm was the default option when those things are relevant.
