Security checks for vulnerabilities and agentic risk

Overview

This is a simple Chinese joke-writing skill with disclosed safety limits and no code execution, data access, persistence, or install-time behavior.

Install this skill if you want a lightweight Chinese joke generator. Be aware that it is intentionally scoped toward Chinese-language jokes, so users wanting multilingual joke generation may prefer a broader skill.

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

  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
Findings (2)

Natural-Language Policy Violations

Medium
Confidence
91% confidence
Finding
The description explicitly states the skill creates Chinese jokes, which imposes a language constraint. Because the file does not offer opt-in, fallback, or explain why the skill must be Chinese-only, this is a natural-language locale policy issue under the stated rules.

Natural-Language Policy Violations

Medium
Confidence
88% confidence
Finding
The main skill instruction says to create Chinese jokes, again enforcing a specific language as the default behavior. The document does not indicate that users may request another language or that the locale limitation is justified by a region-specific purpose.
