Double Check Article

Security checks for vulnerabilities and agentic risk

Overview

This is a narrow Chinese proofreading skill with no executable code, persistence, credential access, or hidden behavior.

Install this if you want an opt-in helper for reviewing Chinese text. It should not be expected to proofread other languages unless the skill is revised to say so.

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 and title/instructions state that the skill is for checking and improving Chinese articles only, with no indication that language choice is optional or user-selectable. This is a natural-language locale policy concern because it imposes a specific language constraint without explicit opt-in or justification as a region-specific tool.
