What
When you resume a session, Claude Code now re-arms the Artifact watches it had recorded instead of giving up as soon as one live watch exists. It restores as many as the per-session limit allows and tells you which ones it could not, either because the limit was reached or because the watch could not be proven still valid.
Details
- Cap message: "this session can watch at most <N> Artifacts at once. Ask Claude to stop watching one, then publish one of these again, to turn its replies back on."
- The other case asks you to have Claude watch the Artifact again or publish it again.
- No flag gates this.
