The actual term for a "discovery writer" is a "pantster" - i.e., you're writing by the seat of your pants - and I think that's a reasonable term to adopt here too.
Confession: I'm a pantster in writing both code and prose. In both cases, coming back and writing a spec (an eng spec in the case of code, a synopsis in the case of prose) is a reasonable thing to do. Structure is good, but the point is that it shouldn't get in the way of actually getting started and making some progress.
