Ecommerce Price Monitor

Problem

Sellers monitoring e-commerce prices often face two practical issues: manually refreshing product pages and receiving repeated group alerts for the same price. This skill turns a Douyin product link into a scheduled task: it checks the price at an hourly cadence and sends a WeCom alert only when the price keeps falling, reducing duplicate notifications and manual polling.

How It Works

The workflow is threshold-based. You create tasks with natural-language commands such as:

• Monitor Douyin product https://v.douyin.com/xxxxx alert below 100 yuan
• Batch monitor link1 below 50 yuan, link2 below 80 yuan
• View tasks, Delete task taskID, Pause, Resume, Refresh price taskID, Price history productID

The key rule is not “alert as soon as the price is below the threshold.” It triggers a drop alert when the price is below the threshold and lower than the last checked price. If the price changes but does not break the threshold, it sends a summary notification; if nothing changes, it sends nothing. This is better suited to tracking sustained price cuts rather than repeatedly reporting the same low price.

Boundaries

This skill is oriented toward Douyin product links, and alerts depend on a WeCom group bot Webhook. The source states a free quota of 5 monitoring tasks, with extra tasks charged at 0.5 yuan per task; Taobao, JD, Pinduoduo, or more complex alert logic is custom development. Before use, confirm the product link can be checked, the WeCom bot is configured, and hourly—not second-level—refresh is acceptable.
