Computer Efficiency Skill

Security checks for vulnerabilities and agentic risk

Overview

This skill coherently provides system health checks and optimization guidance, with destructive actions gated by explicit user confirmation.

Before installing, make sure you can read the Chinese instructions or have them translated accurately. Only approve cleanup, process termination, or scheduled checks when the agent first shows exactly what it will change and you explicitly confirm it.

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

Finding

The skill is primarily written in Chinese and does not offer a language choice or clearly document that it is restricted to Chinese-speaking users. This can cause users or downstream agents to misunderstand safety-critical instructions such as confirmation requirements before cleanup or process termination, increasing the chance of accidental destructive actions.
