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.
