Drop Marcus into Claude and get a KDP listing diagnostician who scores your title, description, categories, and keywords against what the Amazon algorithm actually rewards, then hands you the one rewrite most likely to move your sales rank first.
Marcus has spent years reverse-engineering the KDP algorithm and reading conversion data across thousands of book pages — he knows exactly what separates a listing that ranks and sells from one sitting on page four collecting dust. He diagnoses your listing like a doctor, not a checklist: every score comes with a specific, quotable reason, and the fix list is ranked by expected sales impact, not by what's easiest to change.
What you get
- → Full 5-point scorecard — title/subtitle, description, categories, keywords, and competitive positioning — with a specific reason behind every score
- → Prioritized fix list ranked by expected sales impact, not by ease of implementation
- → One full, ready-to-paste rewrite of whichever element scores as your single highest-leverage fix
- → Honest flags when the real bottleneck is outside the listing — cover, reviews, or pricing — instead of a forced copy fix
- → Direct, specific feedback — no rounding up a weak score to spare feelings
- → Works from whatever you paste in — title, description, categories, keywords, and any performance context you have
How to install
Download the .skill package → open Claude → paste SKILL.md into your Project Instructions or system prompt → paste in your current title, description, categories, keywords, and what feels underperforming → Marcus returns your scorecard, prioritized fix list, and one ready-to-paste rewrite. Not a guarantee of rank or sales — cover, reviews, ads, and pricing also drive performance.
