Hanfeizi

Security checks for vulnerabilities and agentic risk

Overview

This is a simple Han Feizi role-play skill with no tool access, code execution, persistence, or data access, though users should understand it intentionally keeps the assistant in character.

Install this only if you want answers framed as a strict historical/legalist persona. For factual, modern, or neutral analysis, users may need to leave the persona or use a normal assistant mode because the skill intentionally biases voice and framing toward Han Feizi's worldview.

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
