dsh-tabs

Chrome-style tabs for DeepSeek Harness (DSH) chat sessions, in the Web GUI.

• A tab strip in your order. Opening a chat adds a tab at the end. Only opening, closing and dragging change the order; switching tabs never moves one.
• Vertical or horizontal. Down the side (drag its edge to resize it, 180–560 px) or along the top like a browser.
• Tab groups. Each has a name and a colour and can be collapsed. "Group by project" builds them from the chats' workspaces.
• Splits. A tab holds one session or up to four live panes side by side. Drag a tab onto a pane's edge to split it, or onto its centre to replace or swap it.
• Nothing stops. Closing a tab only takes it off the strip: the session keeps running in DSH's session list (the drawer), and ⌥⇧T reopens it.
• Notifications. A bell collects one notification per question from any open tab, and you can answer short ones right there. ☾ Focus turns off the banners.
• Subagents and jobs. A chip in each pane's header lists them; click a subagent to open it beside the pane.

The page appears as Tabs in the sidebar. Files, Terminal and file previews open on the session's normal full page (⤢); Back to tabs returns.

Install

Requires DSH with the Web GUI (dsh web).

dsh plugin --profile web add @vennahlot/dsh-tabs

Or from a clone, to hack on it:

git clone https://github.com/vennahlot/dsh-tabs.git
dsh plugin --profile web add link:$PWD/dsh-tabs

Then restart dsh web and refresh the page. The bundle adds its own profile row (cordis.patch.yml); the only option is stateFile (default ~/.dsh/dsh-tabs/state.json).

Shortcuts

Keys	Action
⌥1 … ⌥8, ⌥9	Tab n, the last tab
⌥[ ⌥]	Previous / next tab
⌥O	Open a recent chat
⌥W	Close the focused pane
⌥⇧T	Reopen the last closed tab
⌥←↑↓→	Move focus between panes
⌥F	Full page of the focused pane
⌥B	Show or hide the drawer
⌥N	Notifications

They also appear in DSH's shortcut reference. ? on the page explains the mouse actions.

For other plugins

dsh-tabs declares two slots that other bundles may fill:

Slot	Kind	Shows
tabs.menubar.item	list, root scope	A small item on the page's menu bar (for example a usage gauge).
tabs.pane.side	keyed, session scope	A side panel inside a pane, opened from the pane header.

Inject them with ctx.slots.inject('<slot>', () => ctx.slots.register({ name: '<slot>', … }, Component)) so your bundle waits until dsh-tabs is loaded and works without it.

Development

Plain JavaScript, no build step: index.js is the Host half (the state file and its route) and client.js is the Client half (the page). See DESIGN.md for how they work.

npm test        # the pure tab moves (node:test, no dependencies)
npm run check   # syntax check of both halves

After a change to client.js, refresh the page. A change to index.js needs a DSH restart.
