Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward image-to-Markdown OCR helper, with disclosed cloud processing and no evidence of hidden persistence or malicious behavior.

Before installing, be comfortable with adding the mineru-open-api CLI from a package registry and with sending images to MinerU's cloud OCR service. Avoid using it for highly sensitive images unless that cloud processing and the provider's retention claim meet your needs.

Vulnerability Patterns

Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
Insecure DependenciesIntroduces malicious components through unsafe dependency sources
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
