AgentRank: verify an agent before you pay

Security checks for vulnerabilities and agentic risk

Overview

This skill is a small, disclosed lookup guide for checking an agent or service reputation before trusting or paying it.

Install only if you are comfortable sending the wallet address or domain you want checked to AgentRank/Crest Deployment Systems LLC. Treat the returned score as one input to a trust decision, not as proof of safety or financial advice.

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
