Colleague-Skill Goes Viral: 6800 Stars in 3 Days, AI Replicating Colleagues' 'Soul' Becomes New Trend

Recently, the open-source project Colleague-Skill has gone viral on GitHub, gaining over 6800 stars in three days and sparking trending discussions on social platforms. Using former colleagues' Feishu records, DingTalk documents, email screenshots, or WeChat chat transcriptions—plus user descriptions—it generates a 1:1 digital doppelganger.

It not only replicates a colleague's knowledge base but also their tone, technical norms, and even behavioral patterns (like "passing the buck"). This AI anthropomorphism concept has resonated widely, spawning derivative projects like Ex-Skill, Mentor-Skill, and forming an "Everything Can Be Skill" ecosystem.

However, the project has raised data privacy and ethical authorization concerns—does using former colleagues' records for training violate privacy? Additionally, the uncontrollable nature of its execution poses security risks, requiring vigilance against potential issues.
