This article is out of date and kept only so old links still land somewhere useful.
The slash commands it listed (/wp-setup, /wp-status, /wp-list and so on) belonged to an older way of installing WordPress for Cowork. They no longer exist. You now connect your site as a Claude connector and simply ask in plain English: “list my draft posts”, “design a landing page for…”, “back up my site”.
Start here: How to connect your WordPress site, then what to try first. For a checkup of the connection, use Cowork → Run the check in wp-admin.
