You'll notice
The warning for artifacts shared from outside your org now says specifically if you can edit them
What
When Claude explains that an artifact (a file or piece of content Claude created and shared) came from a different organization, the message now tells you more precisely what kind of access you have. If you have write access, the message now says so explicitly, calling out that the content is untrusted third-party content authored outside your org, rather than using a generic label that didn't distinguish writers from viewers.
Why
Knowing whether you can only view or also edit an externally-sourced artifact helps you judge how much to trust it and what risk comes with it, since content from outside your organization should be treated as untrusted.
