Ui Master Static

Security checks for vulnerabilities and agentic risk

Overview

This is a static UI/CSS guidance skill with local examples and no hidden privileged behavior.

Install this if you want a vanilla CSS/BEM UI reference skill. Review generated UI code normally, especially optional animation, localStorage, and Houdini Paint API snippets, but the artifact itself does not request unusual access or authority.

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
