What problem does it solve? Translating an entire book manually is slow and error-prone, and feeding a whole book into a single AI context causes truncation and quality loss. This Skill automates full-book translation by splitting the source into chunks and translating them with parallel sub-agents. ## Core Features & Use Cases - Multi-format pipeline: Converts PDF, DOCX, or EPUB input into Markdown chunks, then rebuilds translated output as HTML, DOCX, EPUB, and PDF. - Parallel sub-agent translation: Assigns one chunk per sub-agent with configurable concurrency (default 8) to avoid context overflow and output truncation. - Resumable and verifiable: Tracks progress via a manifest, detects missing or empty output chunks, and retries failed chunks automatically. - Use Case: Translate an English EPUB novel into Chinese by pointing the Skill at the file; it chunks the book, translates each chunk in parallel, and produces a finished EPUB and PDF with the translated title. ## Quick Start Translate the book at /path/to/book.epub into Chinese and generate the translated EPUB and PDF files.
