[FEATURE] Allow deleting/unpublishing an Artifact #74589

Preflight Checklist

• I have searched existing requests and this feature hasn't been requested yet
• This is a single feature request (not multiple features)

Problem Statement

Once an Artifact has been published from a Claude Code session, there is no way to delete or unpublish it:

1. The Artifact tool available to the model can only publish/redeploy — there is no delete operation. The closest workaround is redeploying an empty stub page over it, which still leaves the URL and the gallery entry alive.
2. The artifact link stays pinned in the bar below the chat prompt box for the rest of the session, with no way to dismiss it.

Proposed Solution

• A delete/unpublish operation for artifacts, available both to the model (Artifact tool) and to the user.
• A way to dismiss the pinned artifact link from the bar below the prompt box.

Alternative Solutions

Redeploying a blank page over the artifact to wipe its content. This is not removal: the URL keeps resolving, the gallery entry remains, and the pinned link stays in the CLI for the session.

Priority

Medium - Would be very helpful

Interactive mode (TUI)

Use Case Example

1. Ask Claude to build an HTML report; it publishes it as an Artifact.
2. Decide you don't want it published after all.
3. Currently: no way to remove it — the best you get is blanking the content, and the link stays pinned under the prompt box.
4. With this feature: delete the artifact and the pinned link disappears.
