llms.txt links resolve

What it checks

The extension reads /llms.txt and collects its Markdown links. It then requests up to the first 8 links that point to the same origin as the site, using HEAD and falling back to GET when the server refuses HEAD. A link passes if it returns a successful response.

Links to other domains are listed but never requested. Fetching them would send a request from your browser to whatever address the site put in its file, and whether a third party’s page works says nothing about the site being scanned.

If the site has no readable /llms.txt, this check does not apply, so a site is not charged for a missing file twice. Whether the file exists is covered by llms.txt present.

Results

Status	When
Pass	Every sampled same-origin link resolves
Warn	One or more sampled same-origin links do not resolve
N/A	There is no readable /llms.txt, it has no Markdown links, or all its links point to other domains

How to fix

Fix or remove the broken links. Agents treat llms.txt as an index, so every dead link costs them a wasted request. The evidence panel lists each broken link with the status it returned.

Point the file at your own documents. Links to other domains are not checked.
