\r \r
Paper to Markdown - Researcher Tool\r
\r Convert PDF files to clean Markdown using MinerU Open API. No API key required.\r \r
Quick Start\r
\r
# Paper to Markdown - Researcher Tool\r
mineru-open-api flash-extract report.pdf\r
\r
# Paper to Markdown - Researcher Tool\r
mineru-open-api flash-extract https://cdn-mineru.openxlab.org.cn/demo/example.pdf\r
\r
# Paper to Markdown - Researcher Tool\r
mineru-open-api flash-extract report.pdf -o ./output/\r
\r
# Paper to Markdown - Researcher Tool\r
mineru-open-api flash-extract report.pdf --pages 1-10\r
```\r
\r
## Language Rule\r
\r
You MUST reply to the user in the SAME language they use. This is non-negotiable.\r
\r
## Capabilities\r
\r
- Extracts text, tables, and formulas from PDF\r
- Supports both local files and URLs directly\r
- Page range selection with `--pages`\r
- Language hint with `--language` (default: `ch`, use `en` for English)\r
- No API key, no signup, no authentication\r
- Max 10MB / 20 pages per document\r
\r
## When to Use\r
\r
- User asks to "read", "extract", "convert", or "parse" a PDF\r
- User shares a PDF file or PDF link and asks for its content\r
- User wants to summarize or analyze a PDF document\r
- User needs PDF content in Markdown format\r
\r
## CLI Reference\r
\r
Run `mineru-open-api flash-extract --help` for all available options.\r
\r
## Data Flow\r
\r
`flash-extract` sends the document to the MinerU API (mineru.net) for processing and returns Markdown. This is a stateless API call — no account, no persistent storage. MinerU is an open-source project by OpenDataLab (Shanghai AI Lab): https://github.com/opendatalab/MinerU\r
\r
## Notes\r
\r
- Output is Markdown only; images/tables/formulas may be replaced with placeholders\r
- For larger files (up to 200MB/600 pages) or precision extraction with full assets, use `mineru-open-api extract` (requires auth via `mineru-open-api auth`)\r
- If the CLI cannot be installed via npm/uv/go, download it from https://mineru.net/ecosystem?tab=cli\r
安全使用建议
This skill is coherent with its description, but it uploads PDFs to mineru.net for processing. Do not use it for sensitive or confidential documents unless you accept that those files will be transmitted to that service. Prefer installing mineru-open-api via a package manager (npm/go) rather than downloading binaries from a website. If you care about supply-chain risk, review the mineru-open-api package source (GitHub repo referenced in SKILL.md) before installing, test the tool on non-sensitive sample PDFs, and check MinerU's privacy policy or hosting details to understand retention/processing guarantees.
功能分析
Type: OpenClaw Skill
Name: paper-to-markdown
Version: 1.0.0
The skill is a legitimate wrapper for the 'mineru-open-api' CLI tool, designed to convert PDF documents to Markdown via the MinerU API (mineru.net). While the tool sends document content to an external third-party service operated by OpenDataLab (Shanghai AI Lab), this data flow is explicitly disclosed in the SKILL.md documentation and is necessary for the stated functionality. No evidence of malicious intent, obfuscation, or unauthorized data exfiltration was found.
能力评估
Purpose & Capability
Name/description ask for PDF→Markdown conversion and the skill only requires the mineru-open-api CLI and invokes its flash-extract/extract commands. The declared install targets (npm, uv, go) and the homepage/repo references align with the stated purpose.
Instruction Scope
SKILL.md instructs the agent to run mineru-open-api flash-extract on local files or URLs and explicitly states the CLI sends the document to the MinerU API (mineru.net). The instructions do not ask the agent to read unrelated files or environment variables, but do transmit user-provided documents to a third-party endpoint — a privacy/data-exfiltration consideration rather than a functional mismatch.
Install Mechanism
Install options are npm/uv/go packages for mineru-open-api which is proportionate. The SKILL.md also suggests downloading a CLI from mineru.net as a fallback; direct downloads are higher-risk than package-manager installs and should be verified before use.
Credentials
No environment variables, credentials, or config paths are required. The lack of required secrets is consistent with the claim that basic flash-extract does not need an API key; a separate auth flow is only mentioned for larger/precision extraction.
Persistence & Privilege
The skill is not always: true and does not request persistent elevated privileges or modify other skills. It simply invokes an external CLI at runtime.
