Book Guitar Lessons

Security checks across malware telemetry and agentic risk

Overview

This skill is a straightforward guitar-lesson booking helper, but users should confirm before sending contact details or creating a booking.

Install this only if you want an agent to help search and book guitar lessons through Lokuli. Before any booking, verify the provider, time, and the name, email, and phone number that will be sent to the external service.

Vague Triggers

Medium
Confidence
94% confidence
Finding
The trigger language is broad enough to activate on generic guitar-related service requests without clearly constraining when booking behavior should occur. In a skill that can search providers and create bookings through an external MCP service, overbroad invocation increases the chance of unintended tool use, mistaken bookings, or collection/transmission of user data when the user did not intend to engage this specific workflow.

Missing User Warnings

High
Confidence
97% confidence
Finding
The skill describes booking via Lokuli and includes a create_booking tool that sends customerName, customerEmail, and customerPhone to an external endpoint, but it does not warn users that their personal contact information will be transmitted off-platform. This creates a meaningful privacy and consent risk because users may provide sensitive contact details without informed understanding that a third-party service will receive them.
