Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward academic-paper search and PDF-reading helper with no hidden execution, persistence, or credential behavior found.

Before installing, be aware that the skill may activate on general PDF or paper-related requests, so users should confirm it is appropriate when handling non-academic documents or sensitive local PDFs. Its network and PDF conversion behavior is expected for the stated research workflow.

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

Vague Triggers

Medium
Confidence
95% confidence
Finding
The trigger list includes broad generic terms such as "academic," "papers," and "pdf," which can cause the skill to activate in situations far beyond its intended scope. This increases the chance of unintended invocation, context hijacking, or the agent selecting this skill when a different tool would be more appropriate, though the skill content itself is not otherwise overtly dangerous.
