## What it is

Open source tool that turns technical books and document collections into a skill, with SKILL.md, chapters, glossary and cheatsheet.

## What it’s for

For studying a book with the agent's help, or making manuals, brand guides and specs searchable without blowing up the context.

## Benefits

- Accepts PDF, EPUB, DOCX, HTML, RTF, MOBI/AZW and markdown
- Generates a skill with a chapter index, per-chapter files, glossary and patterns
- Lets you add material to an existing skill and publish to GitHub
- Validates the rules specific to each agent

## Caveats

- According to the project, it uses 24 to 51 times fewer tokens than loading the whole book; the author's own measurement.
- Respect the usage rights of the content: the MIT license covers the converter, not the documents.
- Scanned PDFs need OCR first.
