signoff-ui is React components for the step where a person signs off on what an agent does. DiffReview gives the agent back each file with only the accepted hunks applied, the rejected hunks and the reviewer's comments. ApprovalCard shows exactly what will run and lets you approve once, for the session or always. For AI SDK 6 and 7, AG-UI and ACP agents, inside assistant-ui, AI Elements or your own chat.
