Security checks for vulnerabilities and agentic risk

Overview

This is a writing-assistance skill that asks users for style details before generating text, with no code execution, credential access, persistence, or hidden data handling.

Before installing, note that the skill is authored in Chinese and may be best suited for Chinese-language writing workflows unless the agent adapts its response language. It otherwise appears limited to user-directed writing assistance.

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 entire skill specification is written as mandatory behavior in Traditional Chinese and provides no indication that the agent should match the user's preferred language or ask for language preference. Under the policy, forcing a specific language without user opt-in is a natural-language locale violation.
