Security checks for vulnerabilities and agentic risk

Overview

This Kindle skill only guides the agent to summarize public Kindle pages and explicitly avoids private account data and copyright-bypass help.

Install this if you want an agent helper for summarizing public Kindle pages. Be aware the skill instructions are written in Chinese and the homepage field formatting may affect platform parsing, but the artifact does not ask for private account access or sensitive local permissions.

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
