A comprehensive, rigorously tested skill for writing copy, building campaigns, and auditing marketing pages. Features progressive disclosure (lightweight router + 9 deep-dive reference modules), two quality gates that ask before guessing, and a universal quality bar (specificity, reader-first, one message per piece, proof over claims, honesty). Includes a 26-prompt eval suite with real benchmark results (+20pp over baseline), raw outputs. Works with any tool that can read SKILL.md

Built this in Claude Code. Tested against 26 marketing prompts (cold email, audits, positioning, etc.)—ran each with and without the skill, graded outputs, published everything. 82.7% vs 62.3% baseline (+20pp). But evals #15, #8, #9, #11 are weaker—I published those honestly too. Two gates that ask before guessing on strategy/positioning, and refuse to audit pages you can't see. Curious if that's helpful friction or annoying. Clone the repo or install the .skill file.
