Linking and the companion file
The crawl did not read this home page, so the link was not tested. 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 40 KB the file is larger than 89 percent of the 2,529 plain-text llms.txt files in this edition, and its 260 links put it ahead of 92 percent of them on link count. The home page declares no generator. Size bucket: 10 to 50 KB. Tranco rank 572. Category: Top 10,000, no category.
Live file: https://comcast.com/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.
