Security audit

Xss

Security checks for vulnerabilities and agentic risk

Overview

This is a simple local reference skill that only prints guidance text and shows no credential access, network use, persistence, or destructive behavior.

Before installing, understand that this appears to be a generic XSS/devtools reference helper rather than a specialized security tool. It should not need credentials, network access, elevated permissions, or persistent background behavior; treat any future version requesting those capabilities as a reason to re-review.

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

Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.

Finding

The description and 'When to Use' section describe activation in very general terms such as 'working with xss' and 'need quick reference,' without defining specific trigger phrases, boundaries, or exclusion conditions. This ambiguity could cause the skill to be invoked in a wide range of ordinary development conversations rather than only when the user explicitly wants this reference tool.
