Graph Summary is one of the book Q&A Graph Commands, invoked as a slash command.

Generates an overall analysis report of the book's knowledge graph. It summarizes scale and structure, analyzes node-type distribution, lists the highest-degree core nodes and tightest concept pairs, and gives an overall assessment with exploration suggestions. Ideal for a bird's-eye view.

> Example: Type /summary — no arguments needed; produces the whole-book graph overview report.
