Security checks for vulnerabilities and agentic risk

Overview

This is a simple Chinese chat-assistance skill with no code, network use, credential handling, file access, persistence, or privileged behavior.

Install this if you want Chinese-language help generating chat topics and improving conversation flow. Be aware that its broad trigger words may activate for general chat-related requests, and it appears intended for Chinese-language use.

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

Vague Triggers

Finding

The trigger phrases include very common terms such as '聊天', '话题', '群聊', and '对话', which are likely to appear in ordinary user requests unrelated to this specific skill. This can cause unintended auto-invocation or routing conflicts, leading the skill to activate outside its intended context and potentially interfere with other skills or user workflows.

Natural-Language Policy Violations

Category

Confidence
82% confidence
Finding

The file’s user-facing description and examples are entirely in Chinese, and there is no indication that the skill supports other languages or that Chinese is a justified locale-specific requirement. This can constitute a language policy issue because the skill implicitly forces a specific language without user opt-in.
