What llms.txt is
A file at /llms.txt listing the pages a site considers worth reading, in markdown, as a curated entry point rather than a crawl. Read llmstxt.org — it is the authority on the design and we are not trying to be.
If you are looking for an llms.txt checker or validator: we are not one, and we do not validate the file's structure. What we publish is a dated probe result per site — whether the file was there when we last fetched it, and what else that site does. If that is what you need, the per-site reports below are it.
How we test it
We fetch /llms.txt and require a 200 with a non-empty body. We do not grade its structure.
This is the weakest of the signals we count and we say so on every report: a file that exists is a declaration, not a capability. It appears in tier 1 for that reason.

llms.txt is one signal among several. The rubric says exactly what we look for and how each tier is reached, and a probe can be requested — the probe decides, never the request.
