Plugins

Archive, unarchive, and delete sessions from a settings page.

Real session deletion with trash and restore, archived cleanup, and batch delete from settings.

Per-message delete for DSH: remove a user message, one reply step, or a whole assistant reply from the derived model context through the official surface-replace contract, and hide it from the visible transcript without rewriting the append-only log.

Per-message delete for DeepSeek Harness — a trash icon beside the copy button on every chat message that removes that message from the derived model context (and the visible transcript) via the official surface-replace contract

Delete sessions from the DSH Web sidebar: adds a Delete action to the session row menu with a risk-consent dialog, then removes the session log, workspace accounting and live session state.

A minimal DeepSeek Harness Web plugin that appends a delete-session item below the archive-session item in the sidebar session row menu, resolved by an exact displayTitle + relative-time match.
