Wenchang Review

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward draft-review helper with no code execution, persistence, credential access, or hidden high-impact behavior.

Before installing, note that the skill includes author promotional links and examples oriented toward Chinese publishing platforms, but its behavior is limited to reviewing or editing drafts you provide.

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
