Module activity 

Structured progress updates: ACTIVITY_SNAPSHOT, ACTIVITY_DELTA.

Activities are how an agent reports what it is doing — searching, reading files, waiting on an API — in a shape the client renders itself, rather than as prose in the reply.

Structs

ActivityDeltaEvent

Mutates an activity’s content with a JSON Patch document.

ActivitySnapshotEvent

Publishes the full content of an activity.
