What it checks
The extension requests /llms.txt and checks the body against the format at
llmstxt.org. A file is flagged when:
- the body is HTML rather than Markdown, which usually means a soft 404;
- the body is under 50 bytes;
- there is no H1 (a line starting with
#), which the format requires; - there are no Markdown links.
It also sends a HEAD request for /llms-full.txt and notes it if present.
That file is a common convention, not part of the llms.txt format, so it never
passes this check on its own.
llms.txt is widely published but has no confirmed consumer yet, so this is a
bonus check: it adds points when present and costs nothing when absent.
Results

How to fix
Publish a Markdown file at /llms.txt with an H1 naming the project and links
to your most important pages:
