Jarvis Fact Checker

Security checks for vulnerabilities and agentic risk

Overview

This skill only tells the agent to verify factual and legal claims before answering, with no code, persistence, credential use, or hidden actions.

Install this if you want a Russian-language fact-checking checklist for legal and factual answers. Be aware it may make the agent more cautious and may prompt source verification or uncertainty statements when sources are unavailable.

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
