Simulating whether you are successful at a particular task. All that needs returned there is pass/fail.But, @Oofta, again, you are not actually talking about simulation. In a simulation system, it has to tell you something about what happened. Why did the roll succeed or fail? What happened? Since the 5e system is not based in anything remotely resembling simulation, then any narration is equally applicable.
Or consider this:Player: I would like to negotiate with the merchant for a discount.
Dm: Ok, fair enough. Gimme a Persuasion check.
Player: 23. I fart on him.
DM: Great, you get a 20 per cent discount.
Is a perfectly reasonable result from the 5e skill system because success or failure is not in any way tied to the narrative or the game world.
Player: I would like to negotiate with the merchant for a discount.
Dm: Ok, fair enough. Gimme a Persuasion check.
Player: 23. I fart on him.
DM: It smelled so bad he gave you a 20% discount just to get you to leave quicker (Even with the +10 difficulty increase in DC due to your method of persuasion).
Describing the results of a skill check is all about tying the pass/fail result and the characters actions into the fiction.
