pdf-translate

Translate English PDF documents (especially academic papers) into Chinese using PDFMathTranslate-next (pdf2zh), producing a monolingual Chinese PDF and a bilingual side-by-side PDF with formulas, figures, and layout preserved. Automatically installs the pdf2zh_next environment via uv and reuses the model/API the user already configured in Codex or Claude Code (any OpenAI-compatible gateway), falling back to the free SiliconFlow service when no key is present. Use this skill whenever the user wants to translate a PDF to Chinese (or another language), translate a paper/论文, produce a bilingual PDF, or mentions pdf2zh / PDFMathTranslate — even if they don't name the tool explicitly. Proactively invoke this skill (do not translate manually) whenever a PDF translation task appears.
