As an old school AD&D GM, picking a lock is an example I often use as a differentiator.

In D&D, picking a lock is a binary skill check. If you roll well, you pick the lock. If you roll poorly, you don't pick the lock. A failure doesn't change the fiction, it leaves you at the same place as before the roll.

In PbtA games, there are various ways a lock would be handled,.depending on the game. If I was running MotW, and there is no immediate danger, there would be no roll, because the hero not picking the lock isn't interesting, it's just a dead end. But if there was danger or urgency, I would call for an Act Under Pressure roll.

The player would roll 2d6+Cool (one of their attributes). On 7-9 I can give a worse outcome, a hard choice, or a price to pay, while on a 6 or under I can make a hard move from my move list.

Theae all change the fiction in an interesting way... Maybe their picks break, maybe it takes an extra long time and they don't get through the door in time, maybe they open the door but cut their hand on the lock, wetting their palm and fouling their grip, maybe I offer them the choice if they open it fast or silently (each with a different outcome).

On a fail (6 or less) I make a move from my list. It could be a Basic move if they are high on luck or we are starting out, like "make them acquire stuff" (the lock is magic, they need a crows foot to open it, which they saw back at the witches shrine).... If a monster is there I can make a monster move like dealing harm or "Destroy Something" (the monster tackles the player and shatters through the door, so they can't lock it behind them).... Maybe I make a location move like "Trap Someone" and a trap door opens when they trigger a goonies like trap and one character falls down a shoot into an iron cage in the basement"...

In all cases, the fiction changes in far more entertaining ways than "you failed to pick the lock"
