Security audit

Xlsx To Markdown

Security checks across malware telemetry and agentic risk

Overview

This is a disclosed Office-document-to-Markdown skill whose main risk is that documents are uploaded to MinerU’s cloud service for conversion.

Install only if you are comfortable using MinerU’s CLI and cloud processing. Do not use it for confidential, regulated, or private Office documents unless uploading them to MinerU is acceptable, and only authenticate with MinerU if you need the larger-file workflow.

Vague Triggers

Finding
The skill’s trigger guidance is broad enough to activate on generic requests to read, extract, summarize, or analyze office documents, which can cause the agent to invoke this skill in situations where a safer local parser or a privacy-preserving workflow would be more appropriate. In this skill, that overbroad routing is more dangerous because the documented behavior sends documents or URLs to a third-party cloud API without authentication, increasing the chance of unintended external data disclosure.
