But we’re not even dealing with a programming language in any classical sense here. Interacting with an LLM coding system is a multi-mode communication system with on-demand, purpose-generated ephemeral UI. That doesn’t fit any of the established categories, so I think carrying over constraints from them doesn’t make sense either.

Nope, it's a fixed, coded and shipped UI: the agent TUI.

Even Claude Code can whip up interactive, tabbed, multiple choice questions for example. If you use the superpowers plugin, it'll sometimes spawn a small web server demoing UI concepts or previewing more complex choices using LLM-generated HTML. Claude Code on the web will do even more involved React apps on the fly next to the chat. There's no technical reasons this couldn't get more complex, or vertically integrated with code editors.

I'd definitely call that on-demand, purpose-generated ephemeral UI.
