Excel To Markdown

This skill appears to do what it says: it runs the mineru-open-api CLI to upload and convert documents to Markdown. Before installing or using it, consider: (1) privacy — flash-extract uploads files to MinerU's cloud (verify mineru.net's privacy/storage policy if documents contain sensitive or confidential data); (2) supply-chain trust — prefer installing the CLI from known, verified package sources and check the npm/go package details and repository to ensure authenticity; (3) URL handling — be cautious about passing internal or private URLs (risk of server-side request forgery or exposing private data); (4) for very large or sensitive documents, prefer local/offline conversion tools or verify that the vendor offers guaranteed non-persistence. If you need, I can help locate the mineru-open-api npm package and GitHub repo to inspect release authenticity and source code.
