ex-skill builds an AI persona from exported conversation history and a written description. Its original theme is recreating the style of an ex-partner, but the technical idea is a character profile based on examples.
What the workflow does
You provide chat samples, a nickname or identifier, basic facts, and a personality description. The workflow extracts patterns such as habitual phrases and interaction style, then packages them as a skill. This is a generated imitation, not the person or a reliable reconstruction of their thoughts.
The repository describes chat-export tools, including WeChatMsg for supported WeChat histories. Use data you are entitled to use and consider the other participant’s privacy before uploading it to an AI service.
Using it
The project targets Claude Code. In a compatible AstrBot version, the original article suggests downloading the repository ZIP and importing it through the Skills panel. Check the current repository instructions and your host’s skill support first.
A separate memory plugin may retain more context, but it does not make the imitation accurate or give it unlimited memory. The interesting part is turning a collection of examples into a reusable voice and character definition. The repository has the commands and workflow details.
