Generally speaking, I don't think the subject is simple at all to solve... Automatic success/failure is going to cause a lot of dissatisfaction with some tasks, such as detecting secret doors or traps. Players will just say "from now on, I am always in detect mode" and the DM has to decide if they will always or never find them. That's not fun...
Please let 5e avoid "detect mode" like the plague. Back when I DMed 1e and 2e, players often used the words "detect mode" to mean searching for traps and secret doors every 10'. That meant that their characters were plodding along at a snails pace, there were interminable die rolls, and there was no point in placing traps or secret doors anymore.
Fourth edition dealt with this by assuming that adventurers are cautious by nature, and included Passive checks. No special mode is detected, except for very clueless PCs, you will notice the obvious, and the PCs that are very perceptive notice most things that are moderately hidden.
Rolling for every action and skill was a common way to slow the game down in 3e.
Additionally, just being able to roll once, or roll until you get it, also was a strange mechanic back in 1e. I am thinking not only of secret door searches, but also of open doors rolls. I hated when the strong PC, who opened the door on 1-5 out of 6, failed, but the weak PC, who only opened the door on 1 out of 6, succeeded. The first time it happens, the PCs joke how the strong guy must have loosened the door (if so, why couldn't he try again?). The second, third, etc. times, it's just obvious metagame rules mechanics, laughable, and unsatisfying.
