titanwings/ex-skill
A tool that distills chat history from messaging apps into AI persona Skills that simulate how specific people communicated.

EX.SKILL transforms chat history (WeChat, iMessage) plus user descriptions into digital persona Skills for AI agents. It analyzes conversation patterns, tone, and communication style to generate a skill that behaves like the target person. The system integrates with Claude Code, DeepSeek Harness, and AgentSkills frameworks, allowing generated personas to be used as agent capabilities. Users feed in conversation logs and descriptive context, and the pipeline produces a reusable skill definition representing the distilled personality.
