dsh-computer-use-windows

English | 中文

A Windows-only Computer Use plugin for DeepSeek Harness. It is based on 988hj7tczd-oss/dsh-computer-use and uses cua-driver for Windows UI Automation, an isolated agent cursor, and window-scoped actions. Optional screenshot understanding is provided by Zhipu GLM.

Requirements

• Windows 11 (currently tested on 10.0.22000.2538, x86_64)
• DeepSeek Harness Web profile
• Node.js 24.14.0 (tested version)
• cua-driver 0.21.0 (tested version)

This repository is intended for Windows only.

Tools

Installation

1. Install and start cua-driver

Follow the official cua-driver instructions, then verify the installation:

cua-driver --version
cua-driver doctor --json

If the executable is not in PATH, set:

$env:CUA_DRIVER_BIN = "C:\path\to\cua-driver.exe"

The plugin also probes this common Windows installer location:

%LOCALAPPDATA%\Programs\Cua\cua-driver\bin\cua-driver.exe

Start the daemon:

cua-driver serve --socket "\.\pipe\cua-driver"

2. Add the plugin to the DSH Web profile

Use the included native Windows installer (recommended):

.\tools\install-windows.ps1

It links the plugin into the Web profile, updates the profile package.json, and verifies that dsh-tools resolves to one host-owned instance. Restart the existing dsh web host afterward.

Manual setup is also available. Clone the repository:

git clone https://github.com/qphotoai/dsh-computer-use-windows.git
cd dsh-computer-use-windows

Link the checkout from the Web profile and add it to that profile's package.json:

{
  "dependencies": {
    "dsh-computer-use": "link:C:/path/to/dsh-computer-use-windows"
  },
  "dsh": {
    "profile": {
      "bundles": ["dsh-computer-use"]
    }
  }
}

Do not install another profile-local copy of @deepseek-ai/dsh-tools. The plugin must resolve the exact host-owned module instance; otherwise scheduler identity mismatches can cause undefined.prepare.

Verify the module identity:

$env:DSH_PROFILE_ROOT = "$HOME/.dsh/profiles/web"
node tools/verify-host-modules.mjs

pluginPath and hostPath must be identical. Restart the existing dsh web host afterward.

Uninstall:

.\tools\uninstall-windows.ps1

Usage

Observe before acting:

screen_observe(window="Calculator", mode="ax")
computer_click(element=26)

• window accepts a title substring or PID.
• Element numbers belong to the latest observation.
• A snapshot is valid for about 15 seconds by default; observe again after expiry.
• Prefer mode="ax" for native Windows applications.
• Use mode="vision" for Canvas, images, or incomplete UIA data.

Optional Zhipu Vision

Set a Zhipu API key through the environment:

$env:ZHIPU_API_KEY = "your key"

Alternatively, store a single-line key in:

%USERPROFILE%\.zhipu-key

Restrict the file to the current Windows user and never commit it.

Call vision mode with:

screen_observe(window="target window", mode="vision")

The current implementation calls Zhipu GLM; it does not automatically use the chat model's native vision capability. Vision may misread labels or coordinates, so observe again after an action.

Configuration

The default cordis.patch.yml registers:

- insert:
    - id: dsh-computer-use
      name: dsh-computer-use
      config:
        ttlMs: 15000
        maxElements: 500

Optional settings:

config:
  ttlMs: 15000
  maxElements: 500
  allowedApps: []
  cursorTheme: com.dsh.computeruse.rainbow

• allowedApps: application allowlist; an empty array disables the restriction.
• cursorTheme: ID of a cursor theme already installed in cua-driver; the driver default is used when unavailable.

The upstream theme.lottie and tools/make_theme.py are retained. Follow cua-driver documentation to compile and install cursor themes.

Development

node --check index.js
Get-ChildItem lib -Filter *.js | ForEach-Object { node --check $_.FullName }
node --test test/*.test.js
$env:DSH_PROFILE_ROOT = "$HOME/.dsh/profiles/web"
node tools/verify-host-modules.mjs
