AC Repair

Security checks for vulnerabilities and agentic risk

Overview

This is a simple air-conditioner repair guidance skill with no executable code or hidden privileged behavior.

Before installing, note that the skill is written in Chinese and may be triggered by broad AC repair requests; it appears safe for guidance use, but users should still verify any repair provider, pricing, insurance, and appointment details independently.

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

Natural-Language Policy Violations

Medium
Confidence
88% confidence
Finding
The skill content is entirely written in Chinese and presents the service description and examples only in that language, with no indication that users may choose another language. Under the policy, a language or locale constraint should either be optional for the user or clearly documented and justified as region-specific.

Vague Triggers

Medium
Confidence
94% confidence
Finding
The example trigger phrases are generic enough to match ordinary user requests about air-conditioner repair, which can cause the skill to activate unexpectedly outside a clearly scoped invocation path. This increases the chance of misrouting user intent, unintended tool use, or presenting transactional/service guidance when the user did not explicitly choose this skill.
