llms-full.txt file

The long form of llms.txt — the site content or documentation as one Markdown file, for tools that will read the whole thing in one go.

• Help center

/llms-full.txt is the companion of llms.txt. Where llms.txt is a short map with links, the full version contains the content itself — typically the whole documentation or the key pages of the site — merged into a single Markdown file. A tool that wants to answer questions about your product can read it in one request instead of crawling dozens of pages and stripping out navigation, scripts and layout.

The file is most useful for documentation sites, developer tools and products with a lot of reference material. For a small brochure site it adds little, and like llms.txt it is an informal convention: nothing requires it and the report treats a missing file as a plain fact, not as a warning.

How SiteScan checks

The scan requests /llms-full.txt without following redirects. It counts as published when the answer is a 200 with a non-empty body that is not HTML or XML. A soft 404 page or a redirect to the homepage does not count.

How to produce one

Generate it at build time rather than writing it by hand, so it never drifts from the real content: many documentation generators and static-site plugins can emit it. Strip navigation and boilerplate, keep headings and code samples, and serve it as text/plain or text/markdown. More on the topic: AI visibility.
