Factual Claim Verifier

Security checks for vulnerabilities and agentic risk

Overview

This is a plain fact-checking skill that tells the agent to review and rewrite factual claims without taking external actions.

Before installing, be aware that this skill may cause the agent to fact-check drafts more often and browse for current claims when needed. It is suitable for publication review, but users should still decide when to publish or act on any recommendations.

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

Finding

The trigger guidance is intentionally expansive and includes a catch-all instruction to use the skill whenever a draft contains factual assertions that matter. In an agentic environment, this can cause the skill to activate on many ordinary review or drafting tasks, potentially overriding more appropriate workflows, increasing unnecessary browsing or verification actions, and creating prompt-routing confusion.
