Agent UI v0.1.0 Specification

This page is a historical note. The v0.1.0 specification is superseded by the runtime-first latest specification.

Current guidance

New implementations should ignore v0.1.0 manifest mechanics and implement:

• typed runtime event projection
• message part separation
• tool UI and human-in-the-loop surfaces
• artifact/canvas handoff
• timeline/evidence surfaces
• progressive old-session hydration
• queue vs steer behavior
• controlled writes through runtime, artifact, and evidence APIs

Preserved concept

The preserved idea is surface separation: Conversation, Process, Task, Artifact, and Evidence answer different user questions and should not be collapsed into one plain transcript.
