feat(sdk): type turn.resumed and background.changed system events - #180
Merged
Conversation
The broker emits `turn.resumed` when the agent resumes the last turn on its own (a background task finished) and `background.changed` while idle whenever the set of background tasks holding the devbox awake changes. Both previously classified as `unknown`. Adds the SystemEvent members, parsing, guards, re-exports in every module, and docs. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
The parser passes unknown kinds through, so the type must say so or an exhaustive switch typechecks and misses at runtime. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

What
Adds two broker system events to the SDK's typed
SystemEventunion, shared by the ACP, Claude, and Codex modules:turn.resumed{ turnId }: the agent resumed the last turn on its own, typically because a background task it started finished. SameturnIdas the turn it continues; ends with anotherturn.completed. Parsed liketurn.started.background.changed{ active: BackgroundTask[] }: emitted only while no turn is running, whenever the set of background tasks holding the devbox awake differs from what was last reported.BackgroundTaskis{ id, kind }withkindone ofcommand,agent,workflow; unknown kinds pass through as opaque strings. An emptyactivemeans the agent's background work is done.Both previously classified as
kind: "unknown". AddsSYSTEM_EVENT_TYPESentries, parsing intryParseSystemEvent,isTurnResumedEvent/isBackgroundChangedEventguards with narrowed types, re-exports from/shared,/acp,/claude,/codex, and README / AGENTS docs.Why
Broker side:
turn.resumedis on main (runloopai/runloop#11635);background.changedis runloopai/runloop#11652. The wire shape here matches that PR. Draft until #11652 lands so the shape is final.Checklist
