Context
A buying guide recommended a retailer for a drain auger cable without noticing that Amazon had a cheaper option for the exact same product, visible right in the variation selector on the same product page.
The Problem
Amazon product pages group multiple sizes, lengths, colors, and configurations under one listing with drastically different prices. The buying assistant instructions said to check Amazon but never specified exploring ALL variation options. The agent grabbed the default selection and moved on, missing a cheaper variation.
The Fix
Added a new Amazon variation sweep step (Phase 2, step 5) to the buying-assistant CLAUDE.md. The instruction requires agents to explore all dropdown/button variations on Amazon listings, compare every relevant variation price, and labels missing a cheaper variation as a critical failure.
