Install Chinese Fonts

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward Chinese/CJK font installer whose system package changes are disclosed and aligned with its purpose.

Install this only where you are comfortable changing system or container font packages. Prefer the dry run or verify-only mode first, and run the installer in a privileged shell only when system-wide CJK font installation is intended.

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
