Security checks for vulnerabilities and agentic risk

Overview

This skill is a local USB-C charging compatibility helper and its behavior matches its stated purpose.

This appears safe to install as an offline educational utility. Treat its charging verdicts as guidance and verify against actual hardware labels, certification markings, and manufacturer specs for safety-critical charging decisions.

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
