Extract text and layout structure from images using OCR (Optical Character Recognition). Use this skill whenever the user provides or mentions an image file (screenshot, photo, scanned document, receipt, whiteboard photo, PDF page, etc.) and wants to extract text from it, understand its layout, or get structured information about what's on the image. This skill handles both Chinese and English text, and can identify layout regions (navigation bars, headers, footers, main content, tables, figures, etc.). Also use when the user says "OCR", "提取文字", "图片里的文字", "识别截图", "text from image", "scan this", "read this image" or similar phrases. Do NOT use for pure image generation, image editing, or image classification tasks that don't involve text extraction.

Convert academic PDF papers (especially Chinese academic papers) to well-structured Markdown. Use when the user needs to extract full content from PDF academic papers (thesis, dissertations, journal articles) and convert to Markdown format. Handles text extraction, OCR fallback for font-encoded/custom-encoding PDFs, layout-aware structuring (title/sections/figures/tables/formulas/references), table extraction, math formula preservation, figure caption formatting, and reference list formatting. Not for general PDF manipulation, form filling, or PDF creation tasks.
