Vague Triggers

Medium

Confidence: 89% confidence
Finding: The description uses broad trigger language such as 'reviewing a Skill' and 'check/audit/improve a SKILL.md file,' which can cause the skill to auto-trigger in many generic review contexts beyond its narrow role. Over-broad triggering is dangerous because it can invoke a file-reading and file-modifying skill in situations where a more constrained skill should apply, increasing the chance of unintended edits or misuse.
