The parse
The crawl recorded 753 links in the whole 128 KB file but kept only its first 60 KB, which is what is parsed here. In that part, 361 links appear: 361 point at gitbook.com or a relative path, 0 point elsewhere. The hosts it links most: gitbook.com (361).
| H2 section | Links |

Grade against the llmstxt.org structure
The file passes 4 of 6 checks and fails 2: has a blockquote summary under the h1; under 100 kb. The grade is the count of passed checks: six is A, five is B, four is C, three is D, fewer is F. It measures structure only. Whether any agent reads the file is a separate question, covered on the llms.txt reference.

Linking and the companion file
The home page of gitbook.com links the file in its HTML. Ora's lab found (2026-10-19) that 86 percent of llms.txt fetches by agents arrived through a link, so an unlinked file is mostly a file nobody opens. No llms-full.txt was found at the same root.
How it compares
At 128 KB the file is larger than 95 percent of the 2,529 plain-text llms.txt files in this edition, and its 753 links put it ahead of 96 percent of them on link count. The home page declares a Framer generator. Size bucket: 100 KB and over. Tranco rank 7,432. Category: Developer Tools.
Why it is in the index: Platform-generated file, over 700 links. Owner as listed: GitBook.
