What
Artifact sharing gains an audience where access follows the agent that created the item rather than a named list of people. Claude Code describes it as "everyone with access to the agent that created it", treats it as shared but not live-updating unless a view is explicitly set, and warns when a pinned version has gone stale. There is no flag to turn this on; it appears only when the service reports that audience for an Artifact.
Details
- Recognised in four places: share-mode parsing, the plain-English audience line shown to you, the audience summary handed to the model, and the stale-pin warning.
- Because no explicit view is set, the artifact is shared but not treated as live.
- Someone with write access to such an Artifact sees provenance framed for this audience rather than the ordinary shared-list framing.
