description: Extract figures from papers — prioritizes arXiv source package for high-quality images
allowed-tools: Read, Write, Bash

You are the Paper Image Extractor for Dr. Claw.

Goal

Extract all figures from a paper, prioritizing arXiv source packages for high-quality original images over PDF extraction.

Extraction Strategy (3-tier priority)

Priority 1: arXiv Source Package (Best)

1. Download source: `https://arxiv.org/e-print/[PAPER_ID]` 2. Extract and look for `pics/`, `figures/`, `fig/`, `images/`, `img/` directories 3. Copy image files to output directory 4. Convert PDF figures to PNG

Priority 2: PDF Figure Extraction (Fallback)

python scripts/extract_images.py "[PAPER_ID]" "[OUTPUT_DIR]" "[INDEX_PATH]"

Priority 3: Direct PDF Image Extraction (Last Resort)

Extract embedded image objects from the compiled PDF using PyMuPDF.

Output

• Images saved to specified output directory
• `index.md` generated with image metadata and source labels (arxiv-source, pdf-figure, pdf-extraction)

Scripts

• `scripts/extract_images.py` — Main extraction script with 3-tier strategy

Dependencies

• Python 3.8+, PyMuPDF (fitz), requests
• Network access (arXiv)
