## What it does

The skill runs OCR over scans and image PDFs, adds a text layer behind the images, and makes the document searchable. It handles forms, tables and handwriting, though handwriting quality drops sharply — the skill itself recommends manual review for those pages.

What's inside: skill metadata plus output templates for plain text, structured extraction with sections and tables, and a searchable PDF. MCP integration goes through the `office-mcp` server and the `extract_text_from_pdf` tool. Metadata lists English and Chinese; the language section also covers Spanish, French, German, Italian, Japanese, Korean, Arabic, Hebrew and Hindi.

Check the source scan before you run it: 300 DPI or higher, a straight page, clear contrast. Low resolution or shadows will drag accuracy down, so it's worth rescanning or cleaning the image first. Cursive handwriting lands at 30–60% expected accuracy, which means you can't skip proofreading on those documents.
