Best for

• Developers who want to query technical books from inside their coding agent
• Teams turning internal docs, runbooks, or specs into a reusable skill
• Reducing token usage versus loading whole documents into context
• Users of multiple Agent Skills hosts like Claude Code, Codex, Copilot CLI, and OpenCode

Our take

Pairs a deterministic Python extractor with an agent-driven generator that produces SKILL.md, per-chapter files, a glossary, patterns, and a cheatsheet loaded on demand. Format support depends on optional extractors such as docling, pdftotext, ebooklib, or Calibre, and scanned PDFs need OCR first. The README claims 24x to 51x fewer tokens than dumping a book into context, with methodology documented in the repo.
