Security checks for vulnerabilities and agentic risk

Overview

This is a small Chinese-language coaching prompt about media/content fit, with no code, external calls, data access, persistence, or privileged behavior.

Install this if you want a Chinese-language media-analysis coaching prompt. It appears low risk from a security perspective, but users who need multilingual behavior should confirm the skill works in their preferred language.

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
