book-to-skill: Convert Technical Books and Docs into Agent Skills

Repositoryvirgiliojr94/book-to-skillTool

book-to-skill is an open-source tool that transforms technical books and document folders into standardised agent skills. It enables software engineers to reference and study documentation directly inside coding agents like Claude Code, GitHub Copilot CLI, Amp, or Hermes Agent.

Key points

  1. Converts various formats (PDF, EPUB, DOCX, MD, HTML, RTF, MOBI) and folders into unified agent skills.
  2. Integrates with popular agent interfaces, including Claude Code, GitHub Copilot CLI, Amp, and Hermes Agent.
  3. Claims a 24x to 51x reduction in token usage for single-question retrieval compared to dumping entire books into context.
  4. Written in Python, licensed under the MIT License, and adheres to the open Agent Skills standard.

Why it matters

While large language models support expanding context windows, loading entire technical books remains slow, costly, and prone to retrieval degradation. Pre-processing documentation into modular skills delivers disciplined context engineering for day-to-day software development.

Analysis

The project addresses context bloat and navigation friction when consulting long-form reference material through AI coding assistants. By packaging documents directly as agent skills rather than relying on heavy ad-hoc prompting, it targets developers wanting persistent reference knowledge. Boasting over 28,000 GitHub stars and active maintenance, it demonstrates remarkable adoption and production maturity.

    Cole's AI Skills: Modular Skill Files for Coding Agents

    The GitHub repository 'coleam00/skills' provides a collection of 33 practical skills designed for AI coding agents such as Claude Code. Instead of maintaining a monolithic 2,000-line CLAUDE.md instruction file, each skill resides in a standalone folder with a SKILL.md file and is loaded on demand. The set revolves around a standard development cycle: prime, plan, implement, validate, review, commit, and PR.
