Security checks for vulnerabilities and agentic risk

Overview

This skill is a plain writing-review guide for WeChat/social copy and does not request system access, persistence, credentials, or hidden actions.

Installers should treat this as a persuasive marketing-writing helper. Review rewritten claims for truthfulness, avoid fake proof or artificial urgency, and clarify the intended platform or language when the user asks for generic copy help.

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

Natural-Language Policy Violations

Finding

The skill mixes English structure with Chinese-only usage notes and examples, and its trigger section is entirely Chinese, strongly implying operation in Chinese without an explicit opt-in or documented locale constraint. Because the file does not state that the skill is intentionally region- or platform-specific in language terms, this can be interpreted as a language/locale policy issue.

Vague Triggers

Finding

The trigger phrases are broad enough to capture generic requests for copy help, not just WeChat Moments-specific analysis. This can cause the skill to activate outside its intended scope and steer ordinary writing requests into persuasion optimization, increasing the chance of unsolicited behavioral-influence assistance or misrouting user intent.
