Skill Learner

Security checks for vulnerabilities and agentic risk

Overview

This is a guidance-only skill for recognizing repeated work and suggesting reusable skill knowledge, with no executable code or hidden access.

Before installing, understand that this skill may prompt the agent to notice repeated workflows and suggest skill or rule changes. Review any recommended new skill, script, or local rule before allowing it to be created or modified.

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

Category: Not specified by scanner
Confidence: 92% confidence
Finding: The manifest description says to use the skill when 'patterns repeat,' when the user corrects the same kind of mistake, or when a task keeps requiring the same instructions, which are broad conditions that can arise in many normal interactions. It does not provide concrete trigger phrases, exclusions, or negative examples clarifying when the skill should not be invoked.
