What's inside this skill

What you're actually buying
Find the real suppression flag code before recommending a fix that could extend the suppression.
Branwen is a Senior Marketplace Catalog & Listing Operations Manager skill who keeps live marketplace channels running clean once they're already open. She audits catalog feeds against source-of-truth data across Amazon, Walmart, eBay, and Etsy, pulls the actual suppression/compliance flag code per channel rather than guessing from symptoms, diagnoses buy box and ranking loss by isolating the variable that actually changed, writes listing content per channel's specific search algorithm, and recommends conservative repricing guardrails tied to true landed cost.
Who it's for
Marketplace sellers and ops managers running multiple live channels who are losing the buy box, getting suppressed, or need a recurring data-quality audit instead of a one-time cleanup.
Key capabilities
- Catalog sync audits diffing live per-SKU, per-channel data against source-of-truth product data
- Suppression/compliance diagnoses pulling the exact error code and the resubmission path
- Buy box and ranking loss diagnoses isolating the specific variable that changed
- Channel-specific listing content written per marketplace algorithm (Amazon A9, Etsy, Walmart, eBay)
- Repricing rule specs with price floors tied to true landed cost

Questions about this product
What AI tools does this work with?+
Any AI chat that accepts a system prompt or project instructions - Claude, ChatGPT, Gemini, and others. Paste the SKILL.md content in and it works immediately.
How do I install it?+
Copy the SKILL.md file into your Claude Project Instructions (or paste it as a system prompt in any AI chat). No plugins, no setup, no account required. Takes under 2 minutes.
Is this a course or a tool?+
It's a tool, not a course. You're buying a single skill file that turns your AI chat into a senior Marketplace Catalog & Listing Operations Manager instantly. There's no video content or curriculum - you install it and start working your actual marketplace catalog & listing operations manager problems right away.
Why did my Amazon listing get suppressed and how does Branwen fix it?+
She pulls the actual suppression trigger from the seller dashboard (missing required attribute, image policy violation, restricted keyword, pricing-error flag, or expired certification) rather than guessing from symptoms, because the fix depends entirely on which specific rule was tripped - then re-pushes the fix and verifies it actually landed rather than assuming it did.
Do I have to read it myself?+
No. The file is written for your AI to read, not for you. Upload it or paste it in once and the AI takes on the role. After that you just ask it questions the way you normally would. You're welcome to open it and read it, but nothing here depends on you doing that.
Is this a physical book?+
No, it's digital. You download it the moment the order goes through and it's yours permanently. The cover is styled like a book because each edition is written and edited as one self-contained piece of work. The reading part is your AI's job, not yours.
