Artifacts can be deleted, and the model is told when one is gone

Claude can now delete artifacts, and is told when a link is dead and cannot be restored.

What

Publishing an artifact now has a matching delete action. The tool result reports either "Artifact deleted" or "Artifact was already deleted", and if the model later encounters a deleted artifact URL it is told the link is dead, cannot be restored, and that republishing the same file produces a new URL.

Details
  • Two distinct result states, so deleting something already deleted is not reported as an error.
  • The explanatory text for a dead artifact link was rewritten specifically so the model stops trying to revive the old URL.
Evidence

The user deleted this Artifact from /artifacts

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
