PDF to Markdown - Extract Text, Tables, Formulas from PDF
Convert PDF files to clean Markdown using MinerU Open API. No API key required.
Quick Start
# Convert a local PDF to Markdown
mineru-open-api flash-extract report.pdf
# Convert a PDF from URL (no download needed)
mineru-open-api flash-extract https://cdn-mineru.openxlab.org.cn/demo/example.pdf
# Save to file
mineru-open-api flash-extract report.pdf -o ./output/
# Convert specific pages
mineru-open-api flash-extract report.pdf --pages 1-10
Language Rule
You MUST reply to the user in the SAME language they use. This is non-negotiable.
Capabilities
- Extracts text, tables, and formulas from PDF
- Supports both local files and URLs directly
- Page range selection with
--pages - Language hint with
--language(default:ch, useenfor English) - No API key, no signup, no authentication
- Max 10MB / 20 pages per document
When to Use
- User asks to "read", "extract", "convert", or "parse" a PDF
- User shares a PDF file or PDF link and asks for its content
- User wants to summarize or analyze a PDF document
- User needs PDF content in Markdown format
CLI Reference
Run mineru-open-api flash-extract --help for all available options.
Data Flow
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
Notes
- Output is Markdown only; images/tables/formulas may be replaced with placeholders
- For larger files (up to 200MB/600 pages) or precision extraction with full assets, use
mineru-open-api extract(requires auth viamineru-open-api auth) - If the CLI cannot be installed via npm/uv/go, download it from https://mineru.net/ecosystem?tab=cli
Usage Guidance
This skill appears to do what it claims (call the mineru-open-api CLI to convert PDFs to Markdown), but it uploads the PDFs to an external MinerU API without authentication. Before installing or using it: 1) Do not send sensitive or confidential PDFs unless you trust mineru.net and understand its retention/privacy policy. 2) Verify the mineru-open-api package source (npm/uv) or the GitHub repo referenced in the SKILL.md to ensure you install the official CLI and not a malicious package. 3) If you need offline/local processing for privacy, prefer local extraction tools instead. 4) Test with non-sensitive sample documents first, and inspect the installed binary (or its source) if you require higher assurance.
Capability Analysis
Type: OpenClaw Skill
Name: pdftomd
Version: 1.0.4
The skill is a wrapper for the MinerU Open API (mineru.net) used to convert PDF files to Markdown. It transparently discloses that documents are sent to an external API for processing and provides standard installation methods via npm, uv, or go. No malicious patterns, hidden data exfiltration, or harmful prompt injections were found in SKILL.md or the associated metadata.
Capability Assessment
Purpose & Capability
The skill is a PDF→Markdown converter and declares/uses a single CLI binary (mineru-open-api) and CLI commands that match that purpose. The install options (npm/uv/go) and referenced repo align with the MinerU project named in the README.
Instruction Scope
SKILL.md's runtime instructions are narrow and restricted to invoking mineru-open-api on local files or URLs. However, the instructions explicitly send documents to an external MinerU API (mineru.net). That is coherent with the described capability but has privacy implications: any PDF you convert is uploaded to a remote service.
Install Mechanism
Installation is via standard package ecosystems (npm, uv, go install) which is reasonable for a CLI. This is moderate-risk compared to an arbitrary download because packages come from registries and a GitHub path is provided; you should still verify the package source, version, and code before installing.
Credentials
The skill requests no environment variables, credentials, or config paths. That is proportionate to the stated functionality. The lack of auth is consistent with the claim that small files require no API key, but means uploads are unauthenticated.
Persistence & Privilege
The skill does not request persistent/always-on privileges, does not modify other skills, and has no special system path requirements. It installs a single CLI binary into the environment, which is expected behavior.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install pdftomd - After installation, invoke the skill by name or use
/pdftomd - Provide required inputs per the skill's parameter spec and get structured output
