Moves don't always have to have "when..." triggers that are rooted in the fiction, right? Sometimes they are player-to-player triggers. In AW, there are plenty of examples ("at the start of the session..." or "when there's significant downtime..."). None in the basic moves do that, sure, but...
So maybe:
Spout Lore: when you ask the GM what you know about something, roll +Int. On a 10+, you can ask 3 of the questions below. On a 7-9, ask 1.
...
The downside of this approach, as I see it, is that the hard move on a failure isn't clear. Since there's no fictional action being taken, it makes it hard for the GM to respond with something irrevocable.
