Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
92% confidence
Finding

The manifest’s natural-language descriptions consistently define the skill as a Chinese '朋友圈文案生成器' and all example usages/topics are in Chinese, with no indication that users can choose another language. This imposes a specific language/locale behavior without documented user opt-in or a stated region-specific justification.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
95% confidence
Finding

The prompt template instructs the model entirely in Chinese and directs it to generate a Chinese social-media post. This imposes a specific language on users without any visible opt-in or configurable locale selection, which matches the language/locale policy violation category.
