Linking and the companion file
The home page of frontiersin.org does not link 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 5.1 KB the file is larger than 34 percent of the 2,529 plain-text llms.txt files in this edition, and its 39 links put it ahead of 53 percent of them on link count. The home page declares no generator. Size bucket: 2 to 10 KB. Tranco rank 869. Category: Top 10,000, no category.
Live file: https://frontiersin.org/llms.txt. Read 4 November 2026. If the file has since changed or gone, the live URL is the authority; this page records what the crawl read on that date.
