You'll notice
Artifact tool prompts now warn when someone outside your organization may have edited the artifact
What
When Claude Code asks for permission to use an artifact tool action (such as reading, listing, or deleting files or assets), the description shown now includes a bracketed note reading "[outside writer: someone outside the user's organization may have written to this artifact]" whenever that's the case.
Why
This flags a potential trust concern before an action is approved, letting the user know the artifact may have been modified by someone outside their organization.
