If you ask for a passif that isnt improvised then you decide in advance if they can find it and by whom.
I like to ask for die rolls. Because its a die rolling game. If I want them to know something for free without the risk of them failing it I will use passives as an excuse
Players : we open the door
Me : ok. How exactly are you proceeding ? Do you touch the handle ?
Them fretting for a minute, doing a couple checks, and finally trying the handle
Me : the door opens no problems
Them : what happens ?
Me : nothing special.
Dont worry, I just do it once or twice per dungeon. It helps them remember to check the trapped doors.
A special group of youtubers redid the entire manga series up to a point with voice actors and it's funny as fuck.
For example, Mr. Popo is now a chtuluesk entity that is way stronger than anyone and doesn't give a fuck about anyone's safety.
Try "Mr popo abridged" and enjoy
