wtf is dingyi-edu-radar-skill?

This project is an agent skill, a plugin for AI coding assistants like Claude Code, Codex, and ZCode, that lets those assistants instantly answer two kinds of questions: whether a product has an educational or student discount, and which universities let you sign up for an edu email address and how to do it. The knowledge behind it comes from indexing 249 how-to articles from a Chinese site called edumails.cn, covering 158 articles about education pricing for products such as Replit, Notion, Figma, JetBrains tools, ChatGPT, and Adobe, and 91 articles about applying for edu email addresses at specific universities in the United States and elsewhere. Once installed, you can ask a plain-language question inside your AI assistant, such as whether a certain app offers a student discount or which American colleges let outsiders apply for an edu email, and the skill matches your question against its index, reads the relevant article, and answers with the discount price, application steps, and a link back to the original source. It is designed to answer only from what is in its indexed articles rather than making things up. It installs either through the skills command-line tool, which detects which AI assistant you are using and places the skill in the right folder automatically, or by cloning the repository directly into your assistant's skills directory. On macOS, it can also register a weekly scheduled job that refreshes its article index automatically, using a small script that relies on curl and Python's BeautifulSoup library. The author is explicit that this tool only points to official, publicly available discount programs and legitimate university application channels, and is not meant to help anyone fake student status, forge documents, or buy or sell unauthorized edu email accounts. It is released under the MIT license.
