You'll notice
Auto-replies to Artifact comments can no longer resume for accounts signed in outside the artifact's organization
What
Claude Code's automatic-reply system for Artifact comments gains a new refusal reason, public_outside_org. If an Artifact is public and the account currently signed in is outside the organization that owns it, automatic replies can no longer be resumed. When this happens, Claude Code tells the user about it and is instructed not to retry.
Why
This closes a case where an account outside an Artifact's organization could re-arm automatic replies on a public Artifact, which presumably isn't meant to be allowed across an organization boundary.
