The split is not a marketing decision. WordPress.org forbids a hosted plugin from making external calls, and every remaining part of agent readiness needs one: DNS records live at your DNS host, an alert has to be sent somewhere, and a payment needs a network on the other end.
On WordPress.org, unlimited sites
One site. Everything in Free, plus:
Up to 25 sites
PRO refuses to publish an agentic checkout manifest until there is a real endpoint behind it. An agent that promises a buyer it can complete a purchase, and then cannot, costs the merchant more than the missing feature did.
Anything a plugin genuinely cannot do is listed and explained rather than left out of the total. A tidy hundred percent that hid two categories would be a worse product than an honest eighty.
Content-Signal states a preference to systems that choose to honour it. We say so plainly, because a site owner who believes it is enforcement will make a decision on that belief.
The test is free, needs no account, and tells you what we would fix.
