Error llms-txt-invalid

llms.txt follows the spec

What this check means

Checks that your llms.txt has the structure the llmstxt.org spec defines: an H1 title, a blockquote summary, and at least one section of links.

Why it matters

Parsers read llms.txt positionally. A file missing its title or summary still downloads fine but yields nothing useful when parsed, so the effort of publishing it is wasted.

How we detect it

We parse the file and require a level-one heading, a blockquote immediately following it, and at least one H2 section containing link items.

How to fix it

Open with "# Your Site Name", follow it with "> a one-sentence description", then group links under "## Section" headings.

Check whether this applies to your site.
