Security checks for vulnerabilities and agentic risk

Overview

This is a simple Chinese-language philosophy coaching skill with no code execution, data access, or persistence behavior.

Install this if you want a Chinese-language coach for examining assumptions and arguments through Descartes-style methodic doubt. Non-Chinese users may find the triggers and guidance less accessible, but the artifact does not show security-sensitive behavior.

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

Natural-Language Policy Violations

Medium

Category: Not specified by scanner
Confidence: 93% confidence
Finding: The markdown explicitly presents the skill as '中文使用说明' and all invocation guidance and trigger phrases are defined only in Chinese. This constitutes a natural-language locale restriction without any opt-in, alternative language path, or justification that the skill is intended only for a Chinese-language context.
