Study Plan Builder Skill

Security checks for vulnerabilities and agentic risk

Overview

This skill is a simple study-planning template guide with no executable code, persistence, credential handling, or hidden behavior.

Safe to install for study planning. Users should still avoid pasting private personal data or copyrighted notes they cannot share, and the publisher could narrow the trigger wording to make activation more precise.

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
Vulnerability Patterns
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Vague Triggers

Finding

The activation guidance is broad enough to match many generic education requests, which can cause the skill to trigger outside its intended narrow context. Over-broad routing is risky because it can override more appropriate skills or inject templated behavior where the user did not explicitly ask for this workflow, reducing reliability and potentially bypassing safer, more specialized handling.

Vague Triggers

Category

Confidence

Finding

The example prompt uses very generic language that could act as a broad trigger for ordinary planning requests, increasing the chance of accidental activation. In skill-routing systems, generic trigger phrases can cause prompt collisions and unintended skill selection, which is a control-plane weakness even when the skill content itself is otherwise safe.
