Security checks for vulnerabilities and agentic risk

Overview

This is a simple Hello World greeting skill with no code execution, data access, persistence, or hidden behavior.

This skill is safe to install if you want a Chinese-triggered Hello World response. The only practical caveat is that users may need to know the exact trigger phrase “打招呼”.

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 description specifies activation only when the user says the Chinese phrase “打招呼”, which imposes a language-specific constraint. The file does not offer alternative languages or explain that the skill is intentionally limited to a Chinese-speaking or region-specific context.
