This skill appears to do what it claims (calls the mineru-open-api CLI and optionally uses a MINERU_TOKEN). Before installing or using it with sensitive documents: 1) Confirm whether the mineru-open-api CLI processes files locally or uploads them to mineru.net (check the CLI source and MinerU privacy/API docs). 2) Inspect the npm package and the GitHub repository referenced to ensure the code matches your expectations. 3) Test with non-sensitive sample files first. 4) If you must use real data and the CLI uploads files, limit risk by using a least-privilege token, rotating it if possible, and reviewing MinerU's data retention/privacy policy. 5) If you cannot confirm local-only processing and data confidentiality is required, avoid sending sensitive slides to the service.
