Claude Code v2.1.239 21 Aug 2026

Artifacts toggle no longer shows a setting that failed to save

You'll notice

Useful3 Signal1

Settings

The Artifacts settings toggle now reverts and reports an error if the setting fails to save.

What

Turning Artifacts on or off in settings now waits for the write to finish, and if it fails the row reverts to what is actually stored and the error is returned.

Details

The write was previously fired without waiting, so a failed save left the UI showing the new state anyway.
Both the enableArtifact and disableArtifact values are restored from current settings on failure.

Evidence

enableArtifact

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