Checks
- The paste has one H1, a blockquote summary, and every H2 section contains an absolute http(s) markdown link.
The shape this checker counts
The llms.txt proposal uses one H1 for the site or project name, and that H1 is the only required section. A blockquote carries a short summary. Freeform notes can sit before the first H2. Each H2 starts a file list of markdown links, [name](url), with optional notes after a colon. A heading written exactly as Optional holds links an agent can skip. This page counts those parts in the paste.
The counts describe the text in the box. They do not show whether a host returns that file at /llms.txt, which status it returned, or which crawler fetched it. Vaneform publishes its own agent navigation at /llms.txt, and indexable pages point at it with rel="describedby". The AI crawler page reads allow and deny for robots.txt on one path.
