Context
63 sites in the index share the category SEO. 24 transactional sites share it.
How we grade
Three tiers. Every listing shows which one it has reached, and when. The rubric.
tier 1Declared
The site says agents are welcome in its robots.txt. A permission, not a capability.
tier 2Probe-verified
We fetched the site and tested each signal ourselves. Dated, repeatable, re-checked on a schedule.
tier 3Behaviourally verified
An agent completed the action end to end — booked, bought, submitted — and it worked.
Own this site?
2 checks did not pass when we last looked: llms.txt, MCP server card answers. Each is a small, specific fix; the rubric says exactly what we look for.
Behavioural verification — an agent completing your key actions end to end, with the date published here — opens to a small founding cohort first. Leave an email to be in it.
