Knowledge Digest

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed learning-material generator that creates local study assets and does not show hidden, destructive, or credential-seeking behavior.

Before installing, be aware that this skill can process uploaded learning materials and may use search or generation tools to create files. Use it with documents you are comfortable sharing with the active agent/tools, and review externally sourced courseware when you choose the search-based path.

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
94% confidence
Finding

The trigger description is extremely broad and includes generic phrases like 'learning materials,' 'study notes,' and 'quiz generation,' which can cause the skill to activate for ordinary user requests that were not intended to invoke this workflow. Overbroad activation increases the chance the agent will unexpectedly process uploaded files or launch downstream generation/search behavior without clear user intent, which is a security and consent boundary issue.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The workflow instructs the agent to search the web and compile external materials when the user lacks source material, but the skill description does not clearly warn users of this behavior upfront. This can lead to unexpected data egress, incorporation of untrusted content, and user confusion about whether outputs came from provided materials versus externally gathered sources.
