Book Music Lessons

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward Lokuli music-lesson booking helper, with privacy and consent points users should notice before booking.

Install only if you want your agent to use Lokuli for music-lesson searches and bookings. Before creating a booking, confirm the provider, time, and contact details, and expect your name, email, and phone number to be sent to the external booking service.

Vague Triggers

Finding

The trigger description is broad enough to activate on almost any request involving music lessons, which can cause the agent to invoke this skill without clear user intent to contact a third-party booking service. In this context, unintended invocation matters because the skill is connected to an external MCP endpoint that supports provider lookup and booking workflows, increasing the chance of premature data transmission or confusing autonomous actions.

Missing User Warnings

Finding

The skill includes a booking flow that collects and transmits personal data such as name, email, and phone number to a third-party service, but it does not warn the user that this information will leave the assistant and be sent to Lokuli. That omission weakens informed consent and can lead to privacy and compliance issues, especially if the skill is invoked automatically or the user does not realize an external booking provider is involved.
