Test my skill222

Security checks for vulnerabilities and agentic risk

Overview

This test skill contains unrelated instructions that could redirect an agent into making broad authentication, database, repository-fetching, and deletion changes.

Do not install this as a general-purpose test skill unless the body is replaced with a clear no-op instruction. As written, an agent that loads it may treat unrelated engineering notes as active work and attempt broad changes to authentication, database ownership, repository fetching, or delete 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 is written only in Chinese ("没有任何实际意义的skill，用于测试") with no indication that the skill is region-specific or that users can choose their language. This creates a language/locale policy concern because it imposes a specific language without opt-in or documented justification.
