Security checks for vulnerabilities and agentic risk

Overview

This skill is a local household-cleaner safety checker that warns users not to make dangerous mixtures and provides first-aid guidance.

This appears appropriate for local household safety checks. Users should treat it as first-aid-level guidance only, read actual product labels, and contact poison control or emergency services for real exposures or breathing symptoms.

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
