A new permission reason tells Claude to just retry an artifact action once when the review was based on stale sharing data
When Claude tries to act on an artifact (a generated file or page shown in the conversation), the request is checked against sharing details like ownership, viewers, live-share status, or a stopped watch. That check can now come back with a new reason called server_context_stale, meaning the information used for the review was out of date rather than the action actually being denied. Claude is told to simply repeat the identical call once, and it will be reviewed again against the artifact's current state.
Separately, when an artifact action fails because the artifact changed while it was being reviewed, the interface now shows a specific message explaining that, instead of a generic error.
This stops Claude from treating a timing glitch as a real permission denial, so a single stale check no longer blocks an otherwise valid artifact action.
