Docs Lookup

Security checks for vulnerabilities and agentic risk

Overview

This skill is a focused documentation lookup helper that clearly discloses sending short search queries to an external documentation API.

Before installing, understand that documentation questions may be sent to docs.agentutil.net and paid query/lookup endpoints are described; avoid sending secrets or proprietary code in lookup queries and approve any paid x402 use deliberately.

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
