Why it matters
ai.txt is an informal convention for a site policy on AI use. Few agents read it. This check reports if the file exists and does not change the score.
How to fix it
Publish /ai.txt only when you also keep robots.txt and Content-Usage rules aligned with it.
-
Write your AI use policy in /ai.txt as plain text.
-
Make sure that robots.txt and Content-Usage say the same.
Verify
curl -sf https://{domain}/ai.txt
Expected: HTTP 200 with a plain-text policy
