TokenLab Cost Routing

Security checks for vulnerabilities and agentic risk

Overview

This skill is a small, transparent guide for choosing TokenLab models using public pricing and catalog lookups.

Install only if you intend to use TokenLab pricing/model discovery. Pin or verify the installer source if your environment requires reproducible installs, and keep lookup queries limited to non-sensitive workload categories, model IDs, and pricing assumptions.

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
