Security checks for vulnerabilities and agentic risk

Overview

This skill only gives diagram-selection and generation guidance, with no evidence of hidden execution, persistence, credential access, or destructive behavior.

Installers should expect a Chinese-first diagram helper that can handle English diagram keywords. Review the generated Mermaid or chart configuration before using it in production documents, but there is no artifact-backed security concern requiring Review hold.

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's operational instructions are written as mandatory trigger rules entirely in Chinese, indicating the skill is intended to operate under a fixed language/locale assumption. There is no natural-language note offering multilingual behavior or explaining that the locale restriction is intentional, which can conflict with language/locale policy expectations.
