Vague Triggers

Medium
Confidence
88% confidence
Finding
The trigger language is broad enough to activate on essentially any piano-lessons-related request, which can cause the skill to engage when the user did not clearly intend to use this specific third-party booking workflow. That increases the chance of unintended tool use, unnecessary data sharing, or premature steering into a transactional flow without sufficient confirmation.

Missing User Warnings

Medium
Confidence
94% confidence
Finding
The skill includes a booking flow that collects and transmits personal contact data such as name, email, and phone number to an external MCP endpoint, but it does not instruct the agent to warn the user or obtain clear consent first. This creates privacy and compliance risk because users may not realize their personal information is being sent to a third-party service.
