RouterBase API Integration

Security checks for vulnerabilities and agentic risk

Overview

This is a straightforward RouterBase API integration guide, and its external API examples are disclosed and aligned with that purpose.

Before installing, understand that this skill helps agents write code that sends model requests to RouterBase. Use it only if you intend to route prompts or application data through RouterBase, keep ROUTERBASE_API_KEY server-side, and avoid running live tests unless you explicitly want an API request made.

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
