A style contract that bans AI prose tics and enforces clean, muscular English. It kills em dashes, "it's not X, it's Y" pivots, filler transitions like "at its core," and therapeutic language. You get optional registers (founding fathers, literary modern, cold steel, journalistic) and density controls. Useful when you need essays or rewrites that sound like they were written by a human who reads books, not content marketing. The prohibition list is strict enough to actually change output. Works best when you want forceful, concrete prose and are willing to trade friendly assistant voice for something with edges.
