DSH Session Manager

A client plugin for DeepSeek Harness web that adds a right-click context menu on sidebar conversation rows and a Session manager entry at the sidebar footer.

It answers the frequent request "the three-dot menu has too few options compared to Codex". The stock three-dot menu is hard-coded (no public session-row action slot in 0.1.0-rc.6), so this plugin works around it instead: right-click any session row for a full action menu, and use the footer button for the current session.

Features

Right-click a conversation in the sidebar:

Action	Backing
Pin / Unpin chat	localStorage (dsh.session-pins.v1) — shared with dsh-session-pins
Mark as unread / read	Local state (dsh.session-unread.v1) with a dot on the row; opening a session marks it read
Rename chat	Official sessions.binding(id).session.rename() + a rename dialog
Archive chat	Official workspaces.archiveSession()
Continue in new chat	Official sessions.fork() then open the child
Open in file explorer	Official workspaces.openPath() on the session's workspace
Copy working directory	Workspace path from the workspaces store
Copy session title / ID	Clipboard (writeClipboard)
Copy deep link	Copies <origin>/?session=<id> — opens the session when dsh-deeplink is installed
Open in new window	window.open(.../?session=<id>) — needs dsh-deeplink to land on the session

Sidebar footer "Session manager" (current session): export session ZIP, archive, fork, copy title / ID.

Not implemented (no backend in rc.6): continue in a new working tree, delete-session.

Install

dsh plugin --profile web add github:Semidia/dsh-session-manager#v0.1.1
# recommended companion for deep links:
dsh plugin --profile web add github:qyw233/dsh-deeplink#main
dsh web

Restart dsh web once after adding, then hard-refresh the page. No official package is patched except one additive data-session-id attribute on the session row (see below).

How it works

• A one-line additive patch adds data-session-id to the sidebar session row (@deepseek-ai/dsh-client-ui-workspace → SessionNodeItem). Without it, no public API exposes which session a row represents.
• The plugin registers a capture-phase contextmenu listener and a menu in the public shell.overlay slot, positioned at the cursor via the primitives Menu (portal + getAnchorRect).
• The footer entry registers in the public sidebar.footer.action slot (additive cell, id session-manager, same slot as Session Pins).
• All session/workspace actions use public client services (sessions, workspaces, locale, slots); no private host APIs.

The data-session-id row patch lives in the installed @deepseek-ai/dsh-client-ui-workspace package and is overwritten on a dsh upgrade — re-apply it (one line) after upgrading.

Compatibility

Targets @deepseek-ai/dsh@0.1.0-rc.6. DeepSeek Harness is in developer preview; a new release candidate may change the slot contracts this plugin relies on until compatibility is reviewed.
