What
If file sync stops during a cloud session, Claude Code now asks the host to show a dialog saying sync is offline and that it will work on local files only until service is restored, instead of failing quietly.
Details
- The outcome is reported as
not_shown,dialog,dialog_unansweredorfailed. - No feature flag; if the host does not advertise support for the dialog, the outcome is recorded as
not_shownand nothing is displayed. - Error text passed to the host has control and ignorable characters stripped and is truncated with an ellipsis.
