Extraction Workflow

1. Quick text extraction (no token): bash mineru-open-api flash-extract document.pdf (Outputs Markdown text to stdout)

2. Save extracted text: bash mineru-open-api flash-extract document.pdf -o ./output/

3. OCR for scanned PDFs: bash mineru-open-api extract scanned.pdf --ocr -o ./output/

4. Batch text extraction: bash mineru-open-api extract *.pdf -f md -o ./results/

Key Rules

• Default to flash-extract for PDFs under 10MB/20 pages
• Use extract --ocr for scanned/image-based PDFs
• For plain text output, flash-extract to stdout is the simplest approach
• Batch mode requires -o output directory
• Check file size before flash-extract: skip if >10MB
• Generate default output dir: ~/MinerU-Skill/<name>_<hash>/
