Security checks for vulnerabilities and agentic risk

Overview

This is a simple greeting-style trading-label helper with no sensitive access or persistence, though its documentation is Chinese-only and overstates the actual functionality.

Before installing, understand that this skill appears to be a minimal demo or placeholder rather than a real quant-analysis tool. Non-Chinese users may need translation of the documentation, but the inspected package does not request sensitive access or perform high-impact actions.

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
