Skill Stress Test

Security checks for vulnerabilities and agentic risk

Overview

This is a Chinese-language checklist-style skill for manually stress-testing other skills, with no bundled code or hidden execution behavior found.

Installers should treat this as a manual Chinese-language stress-testing checklist. Be aware that the advertised automation script is not included, so commands referencing scripts/stress-test.py will not work unless supplied separately.

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 skill description is written as a normative product description entirely in Chinese and presents the skill as a general-purpose pre-release stress-testing tool, not a region-specific or Chinese-only tool. Under the language/locale policy, forcing a specific language without user opt-in or justification is a natural-language policy concern.
