Phy Frontend Design

Security checks for vulnerabilities and agentic risk

Overview

This is a frontend design guidance skill with no executable code, persistence, credential handling, or hidden behavior found.

Before installing, understand that this skill may influence many frontend-building or styling requests and push the agent toward bold, distinctive visual choices. Review generated UI code as usual, especially if it adds third-party libraries or remote assets during a later task.

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

Finding

The skill description is broadly scoped to trigger on many common frontend-related requests, including websites, pages, components, styling, and applications. In an agentic environment, this can cause over-activation and inappropriate routing, leading the skill to influence tasks beyond its intended boundaries and increasing the chance that adversarial or irrelevant instructions are applied.
