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

Natural-Language Policy Violations

Medium
Confidence
89% confidence
Finding
The manifest description and main instructions present the skill as operating in Chinese and the example interactions are all Chinese-language, without stating that responses can be adapted to the user's preferred language. This can violate language/locale policy when a skill implicitly requires or defaults to a specific language without opt-in.

Natural-Language Policy Violations

Low
Confidence
85% confidence
Finding
This markdown file presents all user-facing content entirely in Chinese, including the title and usage instructions, with no indication that language is optional or region-specific. Under the policy rule for natural-language violations, forcing a specific language without user opt-in can be flagged when no justification or alternative is provided.
