What
Claude Code can "watch" an artifact (a generated file such as code or a document) so it gets notified when the artifact changes. The explanatory text for this now says background sessions can hold that watch, in addition to interactive sessions and SDK (programmatic) sessions. Subagents, teammates, and print sessions still cannot hold a watch.
Why
This means background work can stay subscribed to artifact updates the same way a session the user is actively looking at can, instead of losing that capability just for running in the background.
