Good question. Really depends on you and your MC. Midnight, the Skinner in our group aske me a workspace for hir perfumes. I gave hir a list of things to do in order to get it, specifically : to get enough distillery and apoticary stuff to set the thing up, a place that locks, and at least two people to help hir, and it'd take at least a week to properly set the place up. As soon as zhe checks it all, the workshop's hir.
On the other hand, Verm the Brainer just took the Angel move to get himself an infirmary. We just roleplayed his finding an old research facility and setting the stuff inside so it'd work on people brains.
I'd say : if you set up the darn thing yourself or spend an advance to get an ad hoc move, sure there you go, use that shit. If not, act under fire THEN I'd tell you the steps to your work AND there'd be at least 3 things and no "or".
For Reality's Fraying Edge, dunno in general. If Dick Boxxer, our fellow Gunlugger, asked me for that move, I'd say "sure, take it, but I'll reveal what's your antenna and believe me, you'll be surprised", I'll note that somewhere and try to present him different things that could be the antenna, and wait for him to bite. Maybe some people he saved. Maybe the radio on the ambulance he found and restored. Maybe his gun collection talking to him.
