dsh-plugin-desktop

English | Русский | 中文

Opens the DeepSeek Harness Web UI in a native window instead of a browser tab.

The plugin does not start a harness of its own. By the time it loads, the process is already listening, so the window simply attaches to it. Ownership stays in one place: the harness outlives the window, and closing the window never takes the server down.

Requirements

The window itself is a separate application, DSH Desktop. The plugin locates and launches it; without it the UI stays in the browser and a warning goes to the log.

Windows only for now.

Installation

dsh plugin --profile web add dsh-plugin-desktop

From a local directory:

dsh plugin --profile web add ./dsh-plugin-desktop

Check that the layer is in place without booting the harness:

dsh --profile web --dump-config

Configuration

The bundle patch already takes the host and port from the webStartup service, that is, from whatever the web app actually bound to.

Field	Meaning
port	Harness port. Taken from webStartup by default.
host	Address. The window only opens for a loopback address.
executable	Full path to dsh-desktop.exe when the search fails.

The search looks in %LOCALAPPDATA%\DSH Desktop, %LOCALAPPDATA%\Programs\DSH Desktop, %PROGRAMFILES%\DSH Desktop, then along PATH.

To override the path in your own profile — $DSH_HOME/profiles/web/cordis.patch.yml:

- id: desktop
  config:
    executable: 'C:\Tools\DSH Desktop\dsh-desktop.exe'

A patch replaces a row's whole config, so an override must restate every field it needs, not only the changed one.

Behaviour

• Server bound to a non-loopback address — the window does not open and the log explains why: a browser is the right surface there.
• The app is already running — a second launch raises the existing window.
• The plugin is unloaded — the window closes, the harness keeps running.
