What would you need to see before letting an AI edit your live website?

I've been building websites with AI for a while now, and the building part is easy. Running the site afterwards is where it fell apart for me. With WordPress plus AI every page came out a little different. With a site written as plain HTML by Claude Code, the rest of the team and our freelancers couldn't edit it anymore.

So we built Caelo, an open-source CMS where the AI only builds from your own design system, works in a draft, and changes to how pages look get a Lighthouse check before they can go out. By default a person clicks publish. It launched on Product Hunt today: Caelo

But I'm curious where others draw the line. Would you let an AI change text on your live site directly? Layouts? Anything at all? And what would have to be in place before you'd trust it?
