I might be missing something, or it might be the fact that I'm not terribly familiar with Powered By Apocalypse, but what does it mean when you're asked to "detail an asset"? I'm assuming you're supposed to write a little more of a description around the item, to make it easier to bring it up in play? So that it isn't just a hand-me-down combat uniform, but also "passed down from girl to girl as a good luck charm, it's rumored the original recipient actually managed to retire" or "has mended spots around the abdomen, about the size of small-caliber pistol round would make"? Basically, just stuff to make it more narratively interesting or to serve as hooks for the story?
What it means mechanically is you add one, but you are definitely encouraged to do stuff like that because assets serve, for the most part, as details for the conversation of a scene. The better defined an asset is, the more it can be a potential lever in the scene.
Most of the assets, especially the Frame ones, provided in the book are named in very evocative but light-on-detail ways as prompts for you to define what *exactly* they are and do on the fiction yourself. How does a "Prey AM" help you in a combat situation? I dunno, but I can tell you its probably not helping you in a stand up fight by the name alone.
