Finding

The manifest description and heading/body content are entirely in Chinese and present the skill as a general-purpose introduction resource, but there is no indication that users can choose another language or that the skill is intentionally limited to Chinese-speaking users. This can violate language/locale policy where skills should not force a specific language without user opt-in or a documented justification.
