Claude Code v2.1.242

Resuming a session restores Artifact watches up to a cap

You'll notice
Useful3 Signal2
Artifacts

Resuming re-arms your recorded Artifact watches up to the session limit and names any it couldn't restore.

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.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
