Security checks for vulnerabilities and agentic risk

Overview

This appears to be a simple placeholder Markdown skill with no commands, permissions, data access, or hidden behavior.

Before installing, treat this as a placeholder or minimal test skill rather than a useful tool. The Chinese text may affect usability if that was not intended, but no sensitive access or unsafe behavior was found.

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 file contains both English and Chinese headings/list items, but there is no natural-language indication that the skill supports multiple languages by user choice or that it is intentionally scoped to a Chinese-speaking context. Under the policy rule for language/locale, forcing or assuming a language without opt-in can be a violation.
