Security checks for vulnerabilities and agentic risk

Overview

This skill is a simple lyrics lookup helper that sends song title and artist queries to a public lyrics API, with no hidden installation, persistence, or privileged behavior found.

Before installing, understand that any song title and artist you ask it to look up may be sent to api.lrc.cx. Avoid using it for private or sensitive unreleased song information if that disclosure matters to you.

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
