What
The artifacts dialog now shows a delete key hint, but only for artifacts you own and only when the session is not a remote one. Deleting keeps the panel open while the request is in flight and blocks Enter, rename, pin and refresh until it finishes.
Details
- An artifact that was already gone is reported as such rather than as a failure: "Artifact was already deleted".
- Delete telemetry now records where it came from (
dialog) and how long since the artifact was last updated. - The hint is suppressed when the remote-session environment marker
CLAUDE_CODE_REMOTEis set.
Evidence
Artifact was already deleted
Strings lifted out of the shipped bundle, so the claim above can be checked against them.

A small documentation edit on Connect Claude Code to an LLM gateway touched a line naming /artifacts after this was published.
