dsh-session-delete

Deleting a session in DeepSeek Harness Web usually means navigating to the sidebar, finding the right conversation, clicking the ellipsis menu, and choosing delete. The catch: that sidebar row menu is hardcoded by the product and exposes no slots for third-party plugins, so there is no safe point of attachment for an add-on. dsh-session-delete closes that gap by placing a single red trash-can button in the officially extensible conversation.session.header.utilities slot, right next to the Session log export button, without obscuring or replacing any native interface.

Clicking the icon triggers a confirmation dialog that follows the current UI language. Upon confirmation it calls the official ctx.workspaces.archiveSession client API: the session is persisted as archived, removed from the sidebar list instantly, and—if it was the active session—the view resets to a blank new-conversation state. A brief "Deleting…" loading indicator keeps the action transparent, and any failure surfaces a clear error message.

The entire plugin runs in the browser, writes nothing to the host side, and disappears completely on uninstall. It is a good fit for DeepSeek Harness users who create sessions frequently and want a quick, safe, one-click way to clean up old conversations without touching host code or risking UI conflicts.
