Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed connector to an external TEACHAiD/SPU web service and does not install code, persist locally, or hide its network use.

Install only if you intend your agent to contact the TEACHAiD/SPU web service. Review remote responses before allowing purchases, financial/accounting actions, curriculum changes, or sharing private student, business, payment, or account information.

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
