Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The trigger terms are very broad and include generic words like '门店', '地址', '营业时间', '预约', and '服务', which can match many unrelated user requests. This can cause the skill to activate outside its intended scope, leading to irrelevant responses, routing mistakes, and possible leakage of brand-specific contact details into unrelated conversations.

Natural-Language Policy Violations

Confidence

Finding

The skill's response-style instructions appear to lock output to a Chinese-only tone without checking the user's preferred language. While not a classic security flaw, this is a safety and usability issue because it can override user intent, reduce transparency, and increase the chance of misunderstanding during sensitive bereavement-related interactions.
