nexscope-ai/eCommerce-Skills ? reverse-engineered prompt

Build me a GitHub repo of plain text AI agent skills for e commerce sellers, organized by topic like product research, pricing, marketing, analytics, inventory, shipping, reviews, and brand protection. I want it to cover the major platforms sellers use, including Amazon, Shopify, eBay, Etsy, TikTok Shop, and Walmart, with lots of ready to use skill folders for specific jobs like keyword research, listing optimization, profit calculations, competitor analysis, and growth strategy.

Make the README feel polished and easy to understand, with a quick start section, examples of how to install a skill, and a few sample prompts a seller could ask an AI assistant. Keep everything simple and useful, focused on markdown based instructions that an AI can read directly. If you need current install or tooling details, look them up online so the setup feels realistic.
