Use Cases & Benefits
- Transforms technical books and document collections into structured agent skills for on-demand study and reference within AI coding assistants.
- Reduces token usage drastically by pre-compiling knowledge into compact, chapter-based skills, avoiding costly repeated context loading and hallucinations.
- Use for integrating your personal or company technical books into GitHub Copilot CLI, Claude Code, or Amp workflows for instant, accurate knowledge retrieval.
- Use for converting internal documentation, runbooks, or onboarding guides into searchable agent skills to streamline developer and team access to key information.
- Use for merging research papers, notes, or standards into unified skills that update over time, enabling deep, structured exploration of specialized knowledge.

From the README
Turn any technical book, document folder, or collection of sources into a unified agent skill — ready to study, reference, and use while you work in GitHub Copilot CLI, Amp, or Claude Code.
🏆 #10 Python Repository of the Day and #25 Repository of the Day on Trendshift (May 23, 2026)
24×–51× fewer tokens than dumping the book into context to answer one question, measured on real books (how it's measured).
How it works, in 3 steps:
You buy a great technical book. You read it once. Three months later you can't remember chapter 7 existed.
book-to-skill solves this by turning the book into a structured skill your agent loads on demand.
Once installed, you just type
/your-book-slug replicationand the agent reads the right chapter and answers from the actual content. No hallucination. No digging through PDFs. The book becomes part of your workflow.Works with any host that supports the open Agent Skills standard — GitHub Copilot CLI, Amp, and Claude Code all read the same
SKILL.mdformat.Running
/book-to-skill your-book.pdf(or a folder, glob, or list of files) creates a full skill in your agent's skills directory (~/.copilot/skills/<slug>/for Copilot CLI,~/.agents/skills/<slug>/for Amp or cross-agent,~/.claude/skills/<slug>/for Claude Code):Chapter files are loaded on-demand — they don't count against the skill budget until you ask about that topic.
