[Feature Request] Artifact tool missing delete/unpublish action

Bug Description
Feature request: Artifact tool can publish and update, but cannot delete What I hit ---------- I published an artifact from Claude Code. Shortly after, I needed to take it down: the content was covered by a confidentiality clause and should not have left my machine. The Artifact tool only exposes action: "publish" and action: "list". There is no delete or unpublish. I had to open a browser, go to claude.ai/code/artifacts, and remove it there. Workaround ---------- Republished the same file_path with a blank page. That neutralises the content immediately and keeps the same URL, but the artifact still exists and still shows up in the gallery. Actual deletion still required the web UI. Why it matters -------------- Publishing from the CLI is one tool call. Retracting is a context switch to the browser. That asymmetry bites hardest exactly when speed matters — the moment you realise something shouldn't be published. NDA / embargoed / competition- confidential material is the common case, and "go delete it in the web UI" is the wrong answer at that moment. Request ------- Add action: "delete" (and/or "unpublish") to the Artifact tool, accepting either url or file_path, mirroring how the update flow already resolves an existing artifact.
