Time Convert

Security checks for vulnerabilities and agentic risk

Overview

This skill is a simple time conversion helper that clearly uses a third-party time API and does not install code, persist itself, or request sensitive access.

Before installing, consider that requests go to a third-party service and may expose your IP in rate-limited form; avoid sending sensitive event details in time strings, and note the stated paid tier if usage exceeds the free allowance.

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
