Security checks for vulnerabilities and agentic risk

Overview

This skill is a transparent literature-search workflow with optional, user-confirmed Zotero import and no bundled executable code.

Install this if you want a structured literature-search and Zotero-import workflow. Before using Zotero features, configure credentials through environment variables or a secret store, confirm the target collection and exact items to import, and avoid authorizing PDF uploads unless the files are open access or you have rights to add them.

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
