But you're describing it in a way that is useless to anything but an LLM. It would have been much better if the description language had been more formalized.

To speculate about this, perhaps the informality is the point. A full formal specification of something is somewhere between daunting and Sisyphean, and we're more likely to see supposedly formal documentation that nonetheless is incomplete or contains gaps to be filled with background knowledge or common sense.

A mandatory but informal specification in plain language might be just the trick, particularly since vibe-APIing encourages rapid iteration and experimentation.

The description includes an input and output json schema.

Only input, not output.

You're not looking at the latest version. They added output schemas.
