This is a detailed copy editing framework that walks Claude through polishing marketing content with senior editor rigor. It breaks down edits into seven checkpoints: clarity, conciseness, active voice, jargon elimination, emotional impact, consistency, and grammar. The structure is methodical, read the full piece first, assess structure, then line edits with before/after examples for each fix. The Hemingway principles are particularly strong, short sentences, cut adverbs, one thought per line. What makes this work is the specificity, it doesn't just say "be clear," it gives you swap tables for cutting fluff phrases and converting passive constructions. Best for polishing landing pages, emails, or ads where every word costs you conversions. The readability scoring at the end helps you match tone to audience.
