Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed Chinese-language guide for using a remote Lingxiao MCP service to build and check marketplace listing drafts, with no hidden code or store-control behavior found.

Before installing, verify you are comfortable sending product listing details to the Lingxiao MCP service. Use the free draft/check tools for local-style validation, and only use paid copy generation when you intentionally provide an account and confirm the charge.

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 entirely in Chinese and states when the skill should be used, but does not indicate multilingual support or user choice of language. Under the policy, forcing a specific language without opt-in is a natural-language policy violation unless the locale restriction is documented and justified.
