Finding
The skill description says to use this skill for ANY Textmagic request, creating a broad routing trigger without clear task boundaries or safety gating. This can cause an agent to invoke the skill automatically for sensitive or high-impact Textmagic operations, including message sending or list creation, even when additional user confirmation or narrower tool selection logic would be more appropriate.
