readthedocs.io llms.txt
In short
readthedocs.io serves a 7.0 KB llms.txt with 5 H2 sections and 40 links, graded C on the llmstxt.org structure (4 of 6 checks). It lacks a blockquote summary and same-site links. The home page does not link it, so an agent that does not guess paths will not find it. An llms-full.txt is served too. Read 4 November 2026.

# Your Documentation Infrastructure Layer
Connect your Git repository and treat docs like code. We run the hard parts: builds, previews, auth -- so you can focus on creating great docs.
## For engineering and docs teams
Your engineering team shouldn't have to run a docs platform team. We run the infrastructure so your writers and developers ship documentation, instead of worrying about pipelines.

Grade against the llmstxt.org structure
The file passes 4 of 6 checks and fails 2: has a blockquote summary under the h1; at least 80 percent of links point at the same site. 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.
| Check | Result | Detail |
|---|---|---|
| Starts with an H1 naming the site or project | Pass | H1: Your Documentation Infrastructure Layer |
| Has a blockquote summary under the H1 | Fail | No blockquote summary before the first H2. |
| Has at least one H2 section that lists links | Pass | 5 H2 sections, 4 with links. |
| At least 80 percent of links point at the same site | Fail | 2 of 34 links stay on readthedocs.io (6 percent). |
| Under 100 KB | Pass | 7136 bytes as served. |
| Plain markdown, no HTML | Pass | No HTML document markers in the body. |
Ora's cached score
Not scored by Ora. GET ora.ai/api/score/readthedocs.io answered 404 DOMAIN_NOT_SCANNED on 5 November 2026, so Ora holds no cached score for this domain. This site asked for a cached score only and never requested a scan. A scan by the site's owner would add one.
Linking and the companion file
The home page of readthedocs.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 7.0 KB the file is larger than 47 percent of the 2,529 plain-text llms.txt files in this edition, and its 40 links put it ahead of 54 percent of them on link count. The home page declares a Pelican generator. Size bucket: 2 to 10 KB. Tranco rank 890. Category: Top 10,000, no category.
Live file: https://readthedocs.io/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.
