Introduction

E-commerce shopping guide requirements are very common in Agent scenarios: users want to know which platform offers a better price for the same product across JD, Taobao, and Pinduoduo, or simply ask the Agent to find the channel with the lowest price. The difficulty of such requirements lies not in the “price comparison logic” itself, but in platform selection and data sources—if developers were to write this themselves, they would need to integrate with three separate platforms and handle the inconsistencies in their respective return structures.

The Skill introduced below consolidates this into a configurable platform selection parameter for direct invocation by Agents.

What is this

The Best Price Shopping Assistant is a community Skill based on the universal SKILL.md format, maintained by the publisher user_b95ee7e5 and categorized as life-service. It solves the problem by allowing the Agent to specify the scope of price comparison in a single call, covering three major e-commerce platforms—JD, Taobao, and Pinduoduo—rather than requiring developers to assemble multi-platform scraping logic themselves.

Version 1.2.1, source labeled as community.

Core Functionality

The core capability currently disclosed by this Skill is solely the specification of platform scope and default behavior:

  • jd: JD
  • taobao: Taobao
  • pdd: Pinduoduo
  • all: All three platforms
  • Default value: all

This means that when the caller does not pass a platform parameter, the Skill defaults to comparing prices across JD, Taobao, and Pinduoduo simultaneously.

Additionally, the Skill is tagged with requires_api_key=false, meaning no API Key is required, thus lowering the configuration threshold.

It should be noted that public materials do not further disclose the specific fields returned by the price comparison (such as price, discounts, links, etc.). This capability is subject to the actual runtime results of the Skill, and no speculation is made in this article.

Installation and Enablement

The Skill’s coordinates are @user_b95ee7e5/best-price-new, and the official address is:

https://api.skillhub.cn/user_b95ee7e5/best-price-new

The SkillHub page is:

https://www.skillhub.cn/skills/user_b95ee7e5/best-price-new

Currently, public materials do not provide universal installation commands, directory structures, or configuration file fields, nor do they offer separate instructions for Cursor / Codex CLI / Claude Code. Therefore, commands are not provided here to avoid giving unverifiable content. It is recommended to open the official address above directly, complete the installation according to the page instructions, and confirm whether the current Agent environment supports the loading method of this Skill.

Typical Usage

The Skill’s introduction only identifies the platform parameter as the single configurable item, and public materials do not provide reproducible complete invocation examples. Based on verified information, the entry point during invocation is the platform parameter:

Platform = jd | taobao | pdd | all   (default all)

For example, when only JD and Taobao need to be compared, simply pass the platform scope; if not passed, the default all applies, covering all three platforms. The specific invocation syntax is subject to the official page.

Applicable Scenarios and Notes

Who it is for:

  • Developers who need to add e-commerce price comparison capabilities to Agents / conversational applications but do not want to integrate with three platforms themselves.
  • Those who only care about shopping guide questions like “which one is cheaper” and can accept scenarios that rely on third-party platform data.

Potential pitfalls to note:

  • This Skill comes from the community (community) and is maintained by an individual publisher user_b95ee7e5. Before use, you should independently evaluate the stability and compliance of the data sources.
  • Public materials only disclose the platform parameters and default values, but not the data sources and update frequency of the price comparison results. Actual effects need to be verified by yourself.
  • The page shows the current installation count is 0. As a relatively new Skill, its ecosystem feedback and long-term maintenance status are unclear.
  • Ratings and download counts are from the SkillHub page and will change over time; the data in this article corresponds to the time of capture.

Conclusion

The value of the Best Price Shopping Assistant lies in consolidating multi-platform price comparison into a platform parameter with a default value, reducing the integration cost for e-commerce shopping guide Agents, and requiring no API Key. If your requirement is exactly for price comparison across JD, Taobao, and Pinduoduo, you can start trying it from the official address.
