Academic Figure Architecture Extractor & Analyzer

Turn paper PDFs or existing architecture images into a structured 架构图分析结果 that handoffs cleanly to color-expert and prompt skills.

Palettes: → ../docs/palettes.md (names only)
Missing info: → ../docs/missing-info-policy.md
Extractor: → scripts/extract_pdf_figures.py

Honest scope

• Prefer user-supplied figure images when available.
• PDF extraction is a real local helper (pdfimages / PyMuPDF / optional pdftoppm), not a trained detector.
• Size filter is heuristic only; architecture vs photo/table is agent judgment.
• Palette: recommend names from docs/palettes.md; hex via color-expert when needed.
