Read, write, and edit EPUB2/EPUB3 ebooks as an EPUB file format expert. Extract text, metadata, structure, and knowledge from EPUB files for enrichment or memory. Create valid EPUBs from scratch. Validate against the EPUB specification. Use when the user mentions epub, ebook, EPUB file, ebook format, read epub, write epub, create ebook, extract from epub, epub to text, or ebook structure. Do not use this skill for unrelated requests; route to the nearest named specialist.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# EPUB — Ebook Creation, Extraction & Enrichment Expert-level EPUB handling: read, write, edit, validate, and extract knowledge from EPUB 2 and EPUB 3 files. Ships with five Python CLI scripts and five detailed references covering the entire EPUB domain. ## When not to use - **Non-EPUB documents** — Word, PDF, plain markdown, or web-page conversion tasks do not match any script here; route them to a document-handling skill instead of forcing an EPUB tool onto a non-EPUB file. - **DRM-locked ebooks** — these scripts read and write standard OCF/EPUB containers; they do not remove or bypass digital rights management. - **Mobi/AZW/Kindle-native formats** — use a dedicated converter first; this skill neither reads nor writes Amazon-proprietary containers. ## EPUB Format Essentials An EPUB file is a **ZIP archive** (Open Container Format, OCF) with a specific internal layout. The W3C EPUB 3.3 standard uses a "three planes" model: | Plane | Contains | Key Rule | |-------|----------|----------| | **Manifest** | All resources (XHTML, images, CSS, fonts) | Every file must be listed in OPF `<manifest>` | …

How to install
mdr add magnus919/agent-skills/epub@sha256:cc5bb93f16e04fe9The line at the top of this page pins the label git:20260902.035e58d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
