That online builder is very cool, well done!
I've been trying out similar things to help internal teams to use systems and languages like Rego (for Open Policy Agent) to have a visual and more 'a la carte' experience when starting out, so they don't have to jump straight to learning all syntax and patterns for a language they might have never seen before.
Thanks, Codex helped to put that together in like 20 minutes. Try feeding your agent the idea about an interactive config builder, give it the upstream URL with your condos, and see if it can whip up something for you.
