What problem does it solve? Manually copying daily store metrics (visitors, traffic sources, add-to-cart counts, conversion rates) from Qianniu/Sycm into Excel is repetitive and error-prone. This Skill automates the collection and writes each metric into the correct Excel column. ## Core Features & Use Cases - Automated Sycm scraping: Connects to a logged-in Chrome session via CDP and reads item archives, item source, and item rank pages for each product ID. - Structured Excel writing: Maps row-1 headers to columns automatically (Pattern A/B layouts), writes visitors, source breakdowns, add-to-cart counts, computed UV values, and add-to-cart rate formulas. - Resumable runs: Saves progress state so interrupted runs resume where they stopped; pauses with NEED_MANUAL_LOGIN when the Taobao session expires. - Use Case: A Taobao seller runs one command each morning to fill yesterday's per-product metrics into their sales tracking workbook. ## Quick Start Ask the assistant to run the taobao-seller-service script with your target date to collect yesterday's store data into your Excel workbook.
