dsh-workspace-split

Keep several live sessions of DeepSeek Harness side by side and type in any of them. Built for supervising several projects at once: you see every session's progress on one screen instead of clicking through tabs.

What it does

A grid of live sessions. Rows and columns are yours to choose, up to 5 × 6. Each tile holds a running session with its full transcript.
Every tile is typable, attachments included. Each cell has its own composer; paste, drop, or pick a PNG / JPEG / WebP / GIF, or attach any other file through the + menu. Uploads are staged through ctx.fileUpload and sent as file parts with the text. The split layout never changes on its own.
Model, reasoning effort, and access mode per tile. The seat under the composer reads the same Session projections and Remote catalogs as Chat, and writes through session.selectModel / /permission <preset>; switching to full access asks for the same risk confirmation.
Slash commands and @ references. A /command line runs through session.command without spending a turn, and @ lists files and sessions through the public reference providers before inserting the same plain-text token Chat uses.
Approvals and questions answer in the tile. An approval or ask_user_question waiting on that Session replaces the composer with a compact card; answering calls the same pending object Chat's panel uses.
Context occupancy. The footer shows the same projected / window token reading as Chat, and hides itself when the projection is absent.
Session or project per tile. Pin one session, or pin a project and switch between that project's sessions inside the tile; a free tile's picker puts the project badge on every row (the same badge as the header) and filters by title or project, with arrow keys and Enter.
Archiving frees the tile. Archive a session in the sidebar and any tile holding it lets go as soon as the Host confirms the archive (one update later; the grid keeps no optimistic copy): a session tile empties, a project tile only drops the session and keeps its scope. Archived sessions leave the tile pickers and drop resolution, and come back when you unarchive them.
Real-time status. A dot on each title shows whether the session is working, and a colored project badge before the title keeps the Session's project visible after the tile has been open for a while.
A click counts as read. The "completed" dot the sidebar lights when a session finishes goes out when you click that tile in split view — no trip back to Chat.
Density that follows the tile. Narrow tiles shrink their text automatically so a small cell still shows a useful amount; Ctrl + wheel over one tile changes that tile alone. The header follows the tile-width density, but not the manual override, so titles stay aligned and do not look oversized beside the transcript.
Markdown and math. Tables, code, task lists, and TeX rendered with KaTeX.
Open an image full-window. Click a picture in the transcript and it fills the window; click anywhere or press Escape to close. The preview renders outside the tile, so per-tile zoom and clipping cannot shrink or cut it.
The process, not just the answer. Reasoning and tool calls fold into one per-turn process group with its elapsed time, a tool call marks itself running until its result arrives, and a status line names what the session is doing. A failed turn shows the provider error instead of ending in silence; with an empty draft the send seat becomes Stop.
Queue, steer, remove. Prompts queued behind a running turn are listed above the composer with Steer and Remove, matching Chat's QueueDock.
Tool calls you can open. Arguments and output inline, failures marked.
Turn rail. Ticks down the right edge jump between turns, including turns not loaded yet.
Layout survives restarts. Grid, assignments, and per-cell zoom are restored.

How sessions are wired

Sessions come from the public ctx.sessions API (list, retain, the event source), and input goes out through session.prompt. Each tile's transcript, Markdown, tool cards, and composer are rendered by this plugin itself, with styles built on DSH's theme variables and visual rules so they match the app.

Everything DSH-specific is consumed through public services and Remote namespaces — ctx.fileUpload, ctx.uiSession, ctx.remote.session, ctx.remote.permissionPresets, ctx.remote.fileReferences, and ctx.remote.sessionReferenceResolver — with one deliberate exception: clearing the completion dot. DSH clears completionUnread only for the main view and exposes no write path, so the tile reads the uiSession instance's own acknowledgement set (completionUnread plus publishStatus()). The reasoning and the fallback are in TECH 13.5, and the plugin moves to the public method as soon as DSH ships one.

test/dsh-contract.test.js asserts those methods and type names — the two private members included — against the installed DSH build, so an upstream rename fails a gate with the exact missing symbol instead of silently breaking a tile; when the private members are gone the dot simply stays lit. Set DSH_CONTRACT_ROOT to check another installation; the test skips when no DSH install is present.

Requirements

DeepSeek Harness 0.2.1-rc.2 or newer (desktop or web).
Desktop app or dsh web; the same build works in both.

Install

dsh plugin add @metal-huang/dsh-workspace-split

Then restart the app (or reload the web page). The toggle appears at the bottom of the sidebar, next to your account.

Installing from a local checkout

git clone https://github.com/metal-huang/dsh-workspace-split.git
cd dsh-workspace-split
npm install
cd packages/dsh-workspace-split && npm install && npm run build
dsh plugin add "$PWD/packages/dsh-workspace-split"

Use

Action	Where
Enter or leave split view	Left-click the ⊞ at the sidebar's bottom
Choose the grid	Right-click that same ⊞
Assign a session	Use a tile's header picker, or drag a session row from the sidebar into the tile
Rename a session	The ✎ next to the tile's title
Resize text in one tile	`Ctrl` + wheel over that tile
Raise the cell limit	Settings → General → Split grid

The cap defaults to 10 cells for the whole screen (12 hard limit per window, both configurable). Six cells fit comfortably; past six, opening more asks for confirmation.

Development

npm install          # repo tooling
npm run check        # lint + duplication + format + tests
npm run build        # rebuild the client bundle
npm run release      # publish a snapshot for the desktop profile

packages/dsh-workspace-split/src/client.js is the source. client.js next to it is generated and not tracked by git — npm install in that package builds it through prepare, and npm run build rebuilds it. Never edit it by hand.

See AGENTS.md for the repository rules and docs/ for the product and design notes.
