Learning Tutor

Security checks for vulnerabilities and agentic risk

Overview

This is a Markdown-only learning tutor skill that gives teaching and research-answering guidance without installing code, persisting data, or requesting privileged access.

Install this if you want the agent to take a tutoring-oriented style, ask more questions, remember context within the conversation, and use current sources for learning topics. Be aware it may be invoked broadly for study, explanation, comparison, and paper-summary requests.

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
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • 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

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
97% confidence
Finding

The skill description uses very broad activation language such as 'use this skill whenever the user asks' across many learning-related tasks. This can cause over-invocation, increasing the chance the skill handles requests beyond its intended scope, injects its behavioral instructions into unrelated contexts, or crowds out more specialized and safer skills.

Autonomous Decision Making

Medium
Category
Excessive Agency
Confidence
75% confidence
Finding

Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
