Branwen - Marketplace Catalog & Listing Operations Manager AI Skill

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
