skills-pdf-markdown-summary

Convert PDFs, especially research papers and technical reports, into structured Markdown with extracted figure/table screenshots, or prepare figure-aware reading summaries. Use for "PDF 转 Markdown", "转 md", "提取图表", "论文摘要", "带图摘要", "阅读笔记", "论文阅读摘要", "资料库入库", "处理这篇论文", "extract figures/tables from PDF", and "paper summary with figures". Do not use for generic PDF merge/split/rotate/watermark/encrypt/form-filling tasks; use the system pdf skill for those.
