dsh-work-chat-switch · 聊天 / 工作

ChatGPT-style switch in the top-left corner of the DeepSeek Harness sidebar, plus an embedded official web chat in the main column.

Button	Tooltip	What it does
聊天 / Chat	无限制使用 / Unlimited use	Switches the central column to https://chat.deepseek.com/, embedded in a desktop <webview> guest
工作 / Work	使用API额度 / Uses API quota	Switches back to the Conversation and creates the next blank session with the API-key provider (deepseek-official)

Install

In the desktop app: open Plugins → Add, paste dsh-work-chat-switch, and confirm. The bundle inserts one Host row and loads its Client half immediately, so the Chat / Work pair appears without a restart.

From a terminal, if dsh is on your PATH:

dsh plugin add dsh-work-chat-switch

A checkout can also be installed as a local bundle (Plugins → Add → local path). No build step and no install-script approval is involved: the published tarball is plain JavaScript.

How it works

The switch

The shipped New Session button is drawn by @deepseek-ai/dsh-client-ui-sidebar and has no plugin slot. This bundle measures that button, hides it with visibility: hidden (its layout box stays, so nothing below moves), and draws the Chat / Work pair in the exact same rectangle from shell.overlay. If the button cannot be found — another build, a shell without it, or the collapsed sidebar rail — the original is restored untouched and the plugin draws nothing.

Switching covers the central column with a frosted layer, swaps the view underneath it, and clears the frost: 250 ms hold + 250 ms fade. Both buttons are disabled while the switch runs.

The Chat panel

chat.deepseek.com answers with Content-Security-Policy: frame-ancestors 'none', so it cannot be iframed. The Desktop app creates browser guests only through its own lease-gated bridge, and this panel uses that same bridge:

1. dshDesktop.browser.acquire(partitionKey) reserves a guest and returns a lease plus the approved partition.
2. A <webview name="<lease>" partition="<approved>" src="about:blank#<lease>"> is attached; the main process rejects any guest without a matching lease.
3. After dom-ready the element navigates to the chat page.

The guest is sandboxed, permissionless, download-blocked, and confined to http(s) navigation. The partition is the app's process-lifetime browser storage: a login entered in the panel survives until the app quits and is shared by every Chat panel in that run, but it is not written to disk. That is a property of the desktop browser, not of this plugin.

Work

Work uses the regular Host session API: uiWorkspace.connectWorkspace, remote.session.selectModel, uiWorkspace.openSession. If no API-key model is routable, it falls back to the deployment default model and shows a short notice under the buttons.

Requirements and limitations

• Verified against DSH desktop 0.2.2-rc.1; package.json declares engines.dsh >= 0.2.2-rc.1 so a market install can be gated by version.
• Desktop app only for the embedded page: the web build has no lease bridge, and the page refuses iframes. Without it the panel shows a message.
• Work needs an API Key (the deepseek-official provider). Without one it falls back to the deployment default model and shows a notice under the buttons — the session still opens.
• The chat page itself must be reachable from your network, and the account must be usable in your region; a blocked or failed load is reported under the panel.
• The Chat login is per app run (process-lifetime partition), as above.
• The switch replaces shipped sidebar chrome; a DSH upgrade that renames or replaces that button can break the replacement (the fallback keeps the app usable but the pair may not appear).
• The New Session keyboard shortcut still starts a session with the deployment default model; the switch only applies to the two buttons.
