Yeah I get that there is a consumer side, I was mainly referring to the technical spec - the "protocol"

I invented something like this months ago to pull up a calculator, browser, etc. in the chat UI (try it chat.blacksand.cloud)

If you prompt what is "2 + 2" it will respond with "4" and render a calculator tool in the chat. It knows what tool to render based on this system.

I guess that is what they are formalizing.

I get it now, cool.
