What file format does the book need to be in?

The skill is specifically designed to process books and technical documentation provided in Markdown (.md) format.

Why does this skill use subagents for extraction?

Subagents are utilized to handle the intensive task of reading specific sections and generating files in parallel, which prevents the main agent from exceeding context limits and ensures higher accuracy.

How does it handle very large books?

It uses a phased approach that starts with a Table of Contents analysis to map line ranges, allowing the AI to process the book in small, manageable chunks without reading the entire file at once.

Can I convert non-technical books into skills?

Yes, while it is optimized for technical guides with code examples, the framework can be used to structure any long-form markdown content into core concepts, rules, and workflows.
