Turn any book into an agent skill
Stop Re-Reading That Book: Turn It Into an Agent Skill That Actually Gets Used.
You bought the technical book, read it once, and three months later can't remember chapter 7 even existed. Searching the PDF gives you page numbers, not answers. Asking your coding agent about it gets you a hallucination. Notes become a 200-line doc you never open.
book-to-skill fixes this — it distills any book, doc folder, or pile of sources into a structured agent skill your coding assistant loads on demand.
How it works (3 steps)
- Point it —
/book-to-skill ./my-book.pdf(also folders, globs, or mixed file lists). - It distills — frameworks, decision rules, anti-patterns, and one file per chapter. Structure, not a summary.
- Your agent loads it — ask
/my-book replicationand it reads the right chapter and answers from the real content. No hallucination.
Why it's worth it
- 24×–51× fewer tokens than dumping the book into context (it pays the "navigation tax" once, at conversion).
- Portable — follows the open Agent Skills standard, so the same
SKILL.mdworks in GitHub Copilot CLI, Amp, and Claude Code. - Beyond books — internal runbooks, brand/design systems, research clusters, RFCs and API specs all become queryable skills.
- Broad format support — PDF, EPUB, DOCX, MD, HTML, RTF, MOBI.
A conversion produces a tidy skill tree: a small SKILL.md core, on-demand chapters/, plus glossary.md, patterns.md, and cheatsheet.md.
