Employee Onboarding Course

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed PersonWise onboarding-course workflow that installs a verified CLI only with approval and uploads user-selected materials for the requested course.

Install only if you intend to use PersonWise for onboarding courses. Expect browser OAuth, possible user-approved CLI or skill updates, use of existing course credits, and upload of the handbook or files you select; keep sensitive HR materials limited to the exact course need and use the default private access unless you really want link/public access.

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
