Agent-First UI v0.1.0: Describe the Interface, Don't Ship It
The first release of Agent-First UI — a protocol where a tool describes its interface as data instead of shipping UI code. A trusted host you own renders the screens and actions, redacts secrets, and gates risky operations, so nothing the tool sends can run on your machine. v0.1.0 ships the wire protocol, a JSON schema, conformance fixtures, and a lightweight Rust SDK.
