Book Math Tutor

Security checks for vulnerabilities and agentic risk

Overview

This skill is a math-tutor booking connector, but it can send personal contact details to an external service and its trigger is broader than explicit booking requests.

Review this skill before installing. It is not evidence of malware, but it should ideally be narrowed to explicit tutor search or booking requests and require confirmation before sending zip code, name, email, or phone number to Lokuli or creating a booking.

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
96% confidence
Finding
The skill documents collection and transmission of personal booking data including customer name, email, and phone number to an external service, but provides no warning, consent step, or privacy notice. In the context of a booking skill, this makes accidental oversharing more dangerous because users may not realize their personal data is being sent to a third-party endpoint during the booking flow.

Vague Triggers

Medium
Confidence
95% confidence
Finding
The trigger language is broad enough to activate on almost any math-tutor-related request without clear limits, increasing the chance the skill is invoked when the user did not explicitly intend to use this third-party booking workflow. Because the skill connects to an external MCP endpoint and can progress toward booking actions, unintended activation can expose user context to a third party or steer users into transactional flows prematurely.
