Security checks for vulnerabilities and agentic risk

Overview

This is a simple Chinese joke-writing skill with no file, network, execution, persistence, or credential behavior.

Install this if you want a skill that defaults to concise Chinese jokes. Users who need multilingual joke generation should know the artifact does not explicitly promise language switching, but it does not show sensitive access or unsafe behavior.

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 manifest description and main instructions state that the skill creates '中文笑话' and should produce Chinese jokes, but there is no indication that users may choose another language. This is a natural-language locale policy concern because it imposes a specific language by default rather than offering language selection or documenting a justified regional constraint.
