Linking and the companion file
The home page of metamask.io 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. An llms-full.txt is served at the same root.
How it compares
At 40 KB the file is larger than 89 percent of the 2,529 plain-text llms.txt files in this edition, and its 131 links put it ahead of 84 percent of them on link count. The home page declares no generator. Size bucket: 10 to 50 KB. Tranco rank 2,234. Category: Top 10,000, no category.
