Book HVAC

Security checks for vulnerabilities and agentic risk

Overview

This skill is a coherent HVAC booking helper, but it can send personal contact details to an external service and create real bookings without clearly requiring user confirmation.

Review this skill before installing. It is not showing hidden code or destructive behavior, but you should only use it when you intentionally want Lokuli to search or book HVAC service, and you should confirm provider, service, time, and the personal details being sent before any booking is created.

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
Vulnerability Patterns

Missing User Warnings

High
Category
Not specified by scanner
Confidence
97% confidence
Finding

The skill instructs use of an external MCP endpoint but does not warn that user data such as ZIP code, name, email, and phone may be transmitted to a third-party service. Because this is a booking workflow tied to an external endpoint, the omission can lead to uninformed disclosure of personal contact and location data.

Vague Triggers

Medium

Confidence
94% confidence
Finding

The trigger condition is broad enough to activate on essentially any HVAC-related request, which can cause the agent to route users into an external booking flow without first confirming intent. In this skill, that increases the chance of premature use of third-party tools and unnecessary disclosure of location or booking-related data.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The create_booking flow performs an external reservation action but the skill does not require a user-facing warning or explicit confirmation immediately before the booking is created. That can result in unintended real-world actions, including appointments made with third-party providers using the user's personal details.
