deusyu/translate-book — reverse-engineered prompt

Build me a Claude Code skill that can translate a whole book file into another language without me manually copying chapters around.

I want to be able to give it a PDF, DOCX, or EPUB and say something simple like “translate this book to Chinese” or “translate this EPUB to Japanese”. It should convert the book, split it into manageable chunks, translate the chunks in parallel, keep names and important terms consistent with a glossary, then merge everything back together.

Please make it safe to resume if something fails, so it doesn’t redo the whole book. It should check that every source chunk has a matching translated chunk before building the final files. The final output should include a readable Markdown file plus HTML with a table of contents, DOCX, EPUB, and PDF.

Use Python scripts where needed, and assume Calibre, Pandoc, and Claude Code are available. Look up current docs online if you need to.
