Finding

The skill advertises broad example requests such as general 'how to use WeChat Work' queries without clearly constraining what the skill should handle. This can cause overbroad activation or routing, where user requests unrelated to the intended safe scope are matched to this skill, increasing the chance of unintended guidance, data exposure through unnecessary engagement, or interference with more appropriate skills.
