Book Dance Lessons

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward dance-lesson booking helper, but users should understand that booking sends their contact details to Lokuli's external MCP service.

Before installing, be aware that creating a booking may send your name, email, phone number, requested time, and selected provider/service to Lokuli. Confirm booking details before allowing the agent to call create_booking, especially if you were only researching lessons.

A.I.G

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Missing User Warnings

High
Confidence
97% confidence
Finding
The skill includes a booking flow that transmits personal contact data such as name, email, and phone number to an external MCP endpoint, but it does not warn the user beforehand or obtain explicit consent for that transmission. This creates a meaningful privacy and compliance risk because users may not understand that their PII will be sent to a third-party service as part of booking.

Vague Triggers

Medium
Confidence
97% confidence
Finding
The trigger description is broad enough to activate on essentially any dance-lessons-related request, which can cause the skill to run in situations the user did not clearly intend. In a booking workflow, unintended activation increases the chance of unnecessary data collection, premature third-party contact, or mistaken transaction initiation.
