Book Tune Up

Security checks for vulnerabilities and agentic risk

Overview

This skill is coherent for booking tune-up services, but it can send personal contact details to an external booking service and create reservations without explicit consent or confirmation instructions.

Review this skill before installing if you are comfortable using Lokuli's external MCP service for tune-up searches and bookings. Only provide contact details when you intend to create a booking, and confirm provider, service, time, and data sharing before any reservation is submitted.

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

Vague Triggers

Medium
Confidence
95% confidence
Finding
The trigger language is broad enough to activate on generic 'tune-up' requests without clearly constraining domain, intent, or confirmation requirements. That can cause the agent to invoke an external booking workflow in situations the user did not intend, increasing the chance of unintended data sharing or unauthorized booking actions.

Missing User Warnings

Medium
Confidence
96% confidence
Finding
The skill instructs use of an external MCP endpoint and includes a booking tool that transmits personal contact details, but it does not warn that this information will be sent to a third-party service. Users may unknowingly disclose name, email, and phone number to an external provider, creating privacy, consent, and compliance risks.
