Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The description says the skill should be used when the user says phrases like “写邮件”, “回这封信”, and especially “帮我措辞”, which are common, broad expressions that can appear in many unrelated contexts. The file does not provide exclusion conditions or tighter trigger constraints, so the invocation scope is ambiguous.

Natural-Language Policy Violations

Low

Confidence
90% confidence
Finding

The instruction “默认中文” sets a language default in natural language, which can violate language/locale choice expectations when the user has not opted in. Although the file later asks whether an English or bilingual version is needed, the default still forces a specific language before user preference is established.
