Security checks for vulnerabilities and agentic risk

Overview

This is a straightforward Chinese social-media writing skill with no code execution, persistence, credential access, or hidden data handling.

Before installing, be aware that this skill may trigger on general writing prompts, not only explicit 小红书, 知乎, 公众号, or 抖音 requests. It appears safe as a writing assistant, but users who want narrower behavior may prefer more platform-specific activation wording.

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 activation triggers are broad enough to match many ordinary writing-related requests, which can cause the skill to activate when the user did not explicitly request this specific tool. In an agent setting, overly broad auto-activation can lead to prompt/context hijacking of normal conversations and unintended behavior selection, even though the skill itself is not directly malicious.
