What is dotyyds1234-skill?

This is a Chinese language repository built around a Twitter user known as Dragon King (handle dotyyds1234). It packages that person's cryptocurrency trading commentary into a file meant to be loaded into AI chat tools like ChatGPT or Claude. The repo has two main parts. First, a full archive of the account's tweets, close to 10,000 of them, covering late 2023 through May 2026 when the account went offline. Second, a file named after the account with a .skill extension. That file distills the account's trading philosophy, described in the README as including the view that the crypto market is largely predatory, along with the account's approach to spotting scams and managing risk, and its distinctive way of writing. The README explains that you are meant to copy the contents of the .skill file and paste it in as a system prompt, meaning the initial instructions that tell an AI assistant how to behave, either at the start of a chat or in a tool's custom instructions setting. Once loaded, the idea is that the AI will respond in the voice and reasoning style of this trader. The README gives examples such as asking the AI how this trader would read the current market, or asking it to apply his logic to a specific coin's funding rate data. A closing note in the README states that the project was generated and distilled automatically from a Twitter scraping plugin, so the tweet archive and skill file were produced by automated extraction rather than written by hand. This looks like a fan project aimed at Chinese speaking cryptocurrency traders who want an AI assistant that mimics one specific trader's public commentary and risk views, rather than a general purpose tool.
