The editor API

Every server-lane operation is an adapter function, which means it is already three things.

One declaration, three surfaces

An operation declared in the catalogue is an HTTP endpoint, an MCP tool and a chatbot functioncall with no registration code. That is why the catalogue is the one place an operation is defined.

The browser lane has no API

And cannot: those operations exist only inside a page. That is not an omission — it is the whole reason your file stays on your machine.
