Usage Guidance
This skill appears to do what it says: it installs a MinerU CLI and uploads documents to MinerU's cloud for OCR. Before installing or using it, consider: (1) MinerU processes files remotely — don't upload highly sensitive documents unless you trust their privacy policy and terms (check https://mineru.net). (2) Installing npm/go packages runs third-party code on your machine; review the package source (or use sandboxing) if you have security concerns. (3) Note the documented limits (10MB/20 pages) and that higher-precision extraction requires explicit auth. If you need offline-only OCR for sensitive content, prefer a local tool (e.g., Tesseract) instead.
Capability Analysis
Type: OpenClaw Skill
Name: scan-to-markdown
Version: 1.0.0
The scan-to-markdown skill provides OCR capabilities by wrapping the 'mineru-open-api' CLI tool. It functions by uploading documents or images to the MinerU cloud API (mineru.net) for text extraction, which is the stated purpose of the skill. No evidence of malicious intent, prompt injection, or unauthorized data exfiltration beyond the documented OCR workflow was found.
Capability Assessment
Purpose & Capability
The name/description (OCR extraction) match the declared binary dependency (mineru-open-api) and the listed install options (npm/uv/go). No unrelated credentials, binaries, or config paths are requested.
Instruction Scope
Runtime instructions call mineru-open-api flash-extract on local files or URLs and explicitly upload documents to MinerU's cloud for processing. This is expected for a cloud OCR service, but it means user data is transmitted externally — the skill does not attempt to read unrelated local files or environment variables.
Install Mechanism
Installation is provided via standard package managers (npm, uv, go install). These are expected for a CLI tool; installing npm/go packages runs third-party code on the host, which is normal but carries the usual supply-chain risk (not an incoherence with the skill purpose). No arbitrary download URLs or archive extraction were used.
Credentials
No environment variables or credentials are required for the advertised 'flash-extract' capability. The SKILL.md notes an optional auth flow for higher-precision features, which would then require credentials — that is documented and consistent.
Persistence & Privilege
Skill is not always-enabled and is user-invocable. It does not request elevated persistence or modify other skills' configurations.
