You'll notice
Artifact listings now also include artifacts shared with you from an external source, merged with your own
What
When Claude Code lists artifacts, it now also queries a second source of externally-shared artifacts (unless the listing scope is explicitly "mine") and merges those results in, marked as shared and external, with duplicates by slug removed. Whether the listing was truncated now also accounts for this second source running out of results.
Why
This lets artifact listings surface artifacts that were shared with you from outside your own set, rather than only your own artifacts.
