Security audit

Supports generating classic ASCII art and colorful emoji pixel art in various themes and styles.

Security checks for vulnerabilities and agentic risk

Overview

This skill only provides instructions for making ASCII and emoji text art, with no code execution, data access, persistence, or privileged behavior.

This appears safe to install for generating text art. Users who do not read Chinese may find much of the guidance less accessible, but the skill does not ask to run commands, read files, access accounts, or persist anything.

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

This markdown skill includes substantial operational guidance in Chinese (for example the usage sections and mode descriptions) while other parts are in English, but it does not tell users that the skill is intended for Chinese readers or offer an alternative language path. That can amount to an implicit language constraint without user opt-in.
