by disler - A single appendable system prompt that retunes Opus 5's communication channel — cutting verbal tics, heading theater, and output-token bloat — passed via --append-system-prompt-file with no build step or dependencies. Comes with a just-driven side-by-side compare loop so you can see the difference, and a set of diagrams breaking down the prompt's anatomy.
