Agent Web

Security checks for vulnerabilities and agentic risk

Overview

This skill openly sends a user-provided public URL to a disclosed web service to return clean markdown, with no local code execution, persistence, or hidden privilege request found.

Install this only if you are comfortable sending the URLs you choose, and the fetched page content, to the disclosed third-party service. Do not use it for private, authenticated, confidential, or access-controlled pages.

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
