Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed local education-planning CLI with broad trigger phrases but no hidden data access, persistence, network activity, or destructive behavior.

Before installing, be aware that common education phrases may activate this skill unintentionally. Its inspected behavior is limited to running a local Python planning script and printing educational templates, with no observed network, credential, persistence, or destructive activity.

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

Vague Triggers

Medium
Confidence
93% confidence
Finding
The trigger list uses very broad, generic educational phrases like "lesson plan," "assessment," and "study schedule," which are likely to appear in normal user conversations. This can cause unintended activation of the skill, expanding its reach beyond explicit invocation and potentially granting Bash-capable functionality in contexts where the user did not mean to use this tool.
