dsh-computer-use 是 DeepSeek Harness 的跨平台 Computer Use 插件,为 AI Agent 增加一套可观察、可约束、可验证的桌面操作能力。
它不是传统的鼠标宏:Agent 必须先观察目标窗口,再基于新鲜快照执行动作。点击、双击和右键操作通过 cua-driver 的独立虚拟光标完成,用户可以看到操作过程,而不是让程序悄悄发送一串不可见事件。
适合用于:
本项目是开源社区插件,不是 DeepSeek 官方产品,也不代表 DeepSeek 的官方立场。
普通文本 Agent 可以生成答案,但无法直接完成很多桌面任务。dsh-computer-use 把桌面交互拆成三个阶段:
观察 Observation → 决策 Decision → 受约束执行 Guarded Action

核心原则:
element 编号,坐标模式保留视觉操作自由度;| 能力 | 说明 |
|---|---|
| 屏幕观察 | 读取目标窗口元数据、Accessibility/AX/UIA 元素和坐标 |
| 三种观察模式 | ax 零视觉 Token、native 主模型直读图片、vision 视觉观察者 |
| 独立虚拟光标 | 点击、双击、右键会显示虚拟光标移动和操作过程,不抢用户真实鼠标 |
| 文本与快捷键 | 输入文本、发送 return、cmd+c、ctrl+shift+p 等按键 |
| 滚动与拖拽 | 支持上下左右滚动和窗口本地截图坐标拖拽 |
| 应用管理 | 列出运行中的应用,后台启动应用,按需前置窗口 |
| 安全护栏 | 快照 TTL、应用白名单、危险操作审批、密码框保护 |
| 跨平台 | macOS 已验证;Windows/Linux 需按真实环境完成平台验收 |
| 工具 | 作用 | 主要参数 |
|---|---|---|

普通桌面用户建议先下载 harness-desktop。它是一个开箱即用的 DeepSeek Harness 桌面客户端,支持 macOS、Windows 和 Linux。
1. 下载并启动 harness-desktop
2. 完成首启配置
3. 安装本插件
4. 重启 harness-desktop
5. 在对话中让 Agent 操作桌面
git clone https://github.com/988hj7tczd-oss/dsh-computer-use.git
cd dsh-computer-use
# 先预演,不写入配置
./install.sh --dry-run
# 安装到用户级 patch 层
./install.sh
# 安装后重启 harness-desktop
安装脚本只做两件事:
$DSH_HOME/profiles/web/node_modules/dsh-computer-use;$DSH_HOME/cordis.patch.yml 注册插件。脚本使用用户级 patch 层,不修改项目代码,也不修改其他 profile 的配置。
install.sh 默认使用 macOS 的 DSH_HOME 路径。Windows 或 Linux 用户请先指定自己的 DSH home:
export DSH_HOME="/path/to/your/dsh-home"
./install.sh --dry-run
./install.sh
如果系统不支持符号链接,请使用宿主 DSH 的插件管理方式,或按照 docs/store-evidence.md 中的手动安装说明操作。
npm install -g dsh-computer-use
安装后仍需要让 DSH profile 加载该 bundle,并确认 cua-driver 已经安装且在 PATH 中,或设置:
export CUA_DRIVER_BIN=/path/to/cua-driver
在 Windows 官方安装器布局中,插件还会自动探测
%USERPROFILE%\\.cua-driver\\packages\\current\\cua-driver.exe;GUI 宿主的 PATH 不完整时无需手工把目录加入 PATH。
安装完成后重启宿主,再通过 app_list 或 screen_observe 验证工具是否出现。
安装并授权后,可以让 Agent 执行下面的任务:
请完成以下桌面任务:
1. 使用 app_list 列出正在运行的应用;
2. 使用 app_launch 打开一个普通桌面应用;
3. 使用 screen_observe 观察目标窗口;
4. 找到目标按钮,优先使用 element 编号点击;
5. 使用 computer_type 输入一段非敏感测试文本;
6. 再次使用 screen_observe 验证文本已经出现;
7. 如果界面发生变化,请重新观察,不要使用旧元素编号继续操作;
8. 如果动作被安全护栏拒绝,请报告拒绝原因,不要绕过护栏。

screen_observe 验证结果
每一次界面明显变化后,都应重新调用 screen_observe。元素编号属于某一次观察快照,不应跨页面、弹窗或长时间等待复用。
screen_observe 的 mode 有三种选择:
| 模式 | 原理 | 成本 | 适用场景 |
|---|---|---|---|
ax(默认) |
读取 AX/UIA 界面树并返回编号和坐标 | 不消耗视觉 Token | 原生应用、元素树完整的界面 |
native |
将截图作为图片块交给当前对话模型 | 图片 Token;不额外调用视觉观察者 | Canvas、游戏、Electron 或 AX 树为空的界面 |
vision |
通过 Harness 的 ctx.llm 调用视觉模型,返回结构化元素列表 |
额外一次视觉模型调用 | 当前主模型不支持图片输入时 |
native 模式当前对话模型必须声明支持 image 输入,例如视觉模型。插件通过 Harness attachments 传递图片,不额外发起独立视觉 API 请求。
screen_observe(mode="native")
vision 模式默认观察模型为:
provider: deepseek-official
model: deepseek-v4-flash-vision-exp
老版本 Harness 需要在模型配置中声明:
models:
- id: deepseek-v4-flash-vision-exp
input: [text, image]
当 DeepSeek 视觉观察者不可用时,插件可以尝试 GLM 视觉兜底。GLM 兜底需要 ZHIPU_API_KEY,并可能受到免费模型访问量限制。
当 AX/UIA 树为空时,插件会尝试:
native(当前路由支持图片时)
→ vision(宿主存在可用视觉模型时)
→ ax(返回可用的界面树信息或明确错误)
从 v0.2.0 起,所有坐标均为:
窗口本地截图像素(window-local screenshot pixels)
这意味着:
screen_observe 输出的 @(x,y) 与 computer_click(x=,y=) 使用同一坐标系;screen_zoom 时,返回图片是局部区域,但点击仍应使用整窗截图坐标。优先使用:
computer_click(element=5)
只有在元素无法通过 AX/UIA 识别,或视觉模式给出坐标时,才使用:
computer_click(x=640, y=420)
screen_observe,动作不会执行;allowedApps 后,只允许指定应用接受操作;AXSecureTextField / AXPasswordField 时拒绝自动输入;allowed-once 不切换焦点、不重试;cua-driver;语义安全检测依赖观察到的元素标签,主要对 element 编号模式有效:
x/y 坐标模式无法提前知道目标语义,主要依赖快照 TTL 和可见操作;computer_type 和 computer_key 作用于当前焦点时,无法预判最终目标内容;computer_key 不会阻止 cmd+q、ctrl+alt+delete 等系统快捷键;插件配置位于 DSH 的用户级 patch 层:

maxElements: 500
allowedApps: []

安装脚本或 bundle patch 可能覆盖代码层默认值。请以实际生成的
$DSH_HOME/cordis.patch.yml为准;多步任务建议显式写入ttlMs,不要依赖隐式默认值。
| 平台 | 状态 | 说明 |
|---|---|---|
| macOS | ✅ 已验证 | 可能需要 Accessibility 和 Screen Recording 权限 |
| Windows | ⛔ BLOCKED | 当前无 Windows 10/11 真机;路径和按键逻辑已测试,真实 GUI 未验收 |
| Linux | ⛔ 未验证 | 桌面环境、Accessibility 栈和窗口管理器可能影响元素识别 |
测试通过不代表所有应用的界面树都完全一致。AX/UIA 不完整时,请使用 native 或 vision 模式,并在提交问题时附上操作系统、目标应用和 screen_observe 输出。
| 现象 | 常见原因 | 处理方式 |
|---|---|---|
cua-driver not found |
引擎不在 PATH 或官方安装器路径不可用 | 安装 cua-driver,确认 ~/.cua-driver/packages/current/cua-driver.exe 存在,或设置 CUA_DRIVER_BIN |
| 没有可见窗口 | 图形会话或窗口权限不可用 | 确认目标应用正在运行并重新观察 |
| 快照已过期 | 超过 ttlMs |
重新调用 screen_observe |
| 元素编号点击失败 | 界面已经变化 | 重新观察后再使用新编号 |
| AX/UIA 树为空 | Canvas、游戏、Electron 或特殊窗口 | 使用 native 或 vision |
| native 被拒绝 | 当前主模型没有 image 输入能力 | 切换视觉模型或使用 vision |
| vision 模型不可用 | provider/model 未注册 image 输入 | 配置 visionProvider / visionModel |
| GLM fallback 不可用 | 没有 ZHIPU_API_KEY 或遇到限流 |
配置 Key,或使用 Harness 视觉模型 |
| 危险操作被拒绝 | 需要用户审批 | 检查审批提示,不要绕过安全护栏 |
| Windows 管理员窗口无法操作 | 目标窗口权限级别更高 | 使用普通用户窗口 |

dsh-computer-use is a cross-platform Computer Use plugin for DeepSeek Harness. It gives an AI agent an observable, guarded, and verifiable desktop action layer.
The plugin is designed around an explicit loop:
Observe → Decide → Execute with Guardrails → Observe and Verify
It can inspect desktop windows, expose actionable AX/UIA elements, use a screenshot-based visual fallback, and operate through an isolated virtual cursor. It is useful for desktop automation, Computer Use research, internal workflows, and agentic applications that need bounded desktop actions.
This is a community plugin, not an official DeepSeek product and not affiliated with DeepSeek.
ax, native, or vision observation modes;Download harness-desktop, the ready-to-use DeepSeek Harness desktop client. After the host is installed, install this plugin and restart the host.
git clone https://github.com/988hj7tczd-oss/dsh-computer-use.git
cd dsh-computer-use
./install.sh --dry-run
./install.sh
The installer creates a user-level plugin link and registers the bundle in the DSH home patch layer. It does not modify project source files or other profiles.
On Windows or Linux, set DSH_HOME to the actual DSH home directory before running the script:
export DSH_HOME="/path/to/your/dsh-home"
./install.sh
npm install -g dsh-computer-use
Make sure the host loads the bundle and that cua-driver is available in PATH, or set CUA_DRIVER_BIN to its absolute path.
On Windows, the official installer layout is also detected automatically at
%USERPROFILE%\\.cua-driver\\packages\\current\\cua-driver.exe, which covers GUI hosts whose PATH does not include the driver.
| Tool | Purpose | Main parameters |
|---|---|---|
screen_observe |
Observe a window, AX/UIA elements, coordinates, or a screenshot | window, mode, query, maxElements |

computer_type |
Type into the focused or selected field | text, optional element |
computer_key |
Send a key or shortcut | key, e.g. return, cmd+c |
computer_scroll |
Scroll a target window | direction, amount, optional element |
computer_drag |
Drag between screenshot coordinates | from_x, from_y, to_x, to_y |
computer_wait |
Wait for a page load or animation | ms, max 60000 |

A snapshot is observation-local. If the UI changes, observe again before using an element index or coordinate from the previous state.
| Mode | How it works | Best for |
|---|---|---|
ax |
Returns a compact AX/UIA tree with indexed elements and coordinates | Native applications with usable accessibility data |
native |
Returns the screenshot as an image block for the current multimodal model | Canvas, games, Electron, or windows with incomplete AX/UIA data |
vision |
Uses a Harness ctx.llm vision model to describe the screenshot |
Text-only main models that need a separate observer |
native requires the current route to declare image input support. vision uses the configured visionProvider and visionModel; the default model is deepseek-v4-flash-vision-exp. The optional GLM fallback requires ZHIPU_API_KEY and may be rate-limited.
When the accessibility tree is empty, the fallback order is:
native → vision → ax
The plugin chooses a path that is available and returns an explicit error when no visual route can be used.
Since v0.2.0, all coordinates are window-local screenshot pixels:
screen_observe and coordinates accepted by computer_click share the same space;screen_zoom returns a cropped image, but click coordinates remain coordinates in the full-window screenshot space.Prefer semantic element actions:
computer_click(element=5)
Use x,y when the target is not exposed through AX/UIA or when a visual observer provides coordinates.
The plugin includes:
allowedApps can restrict the operation scope;cua-driver with fixed argv;Semantic checks are strongest for element-based actions. Coordinate actions and unfocused computer_type/computer_key calls cannot predict the final semantic target. computer_key does not validate system shortcuts. Do not give this capability to an untrusted agent, and always type passwords and secrets yourself.
If the driver reports background_unavailable, the plugin asks for one-time approval before retrying in foreground mode where the current tool/platform supports it; that retry may bring the target window forward. Rejecting or lacking approval leaves the action refused.

| Platform | Status | Notes |
|---|---|---|
| macOS | ✅ Verified | Accessibility and Screen Recording permissions may be required |
| Windows | ⛔ Blocked | Logic/path coverage exists; real GUI validation requires a Windows 10/11 regular-user desktop session |
| Linux | ⛔ Not verified | Desktop environment, accessibility stack, and window manager can affect element discovery |
The macOS path has been verified in the project evidence. Windows and Linux still require a real platform run before they can be advertised as fully tested. This does not mean every application exposes an identical accessibility tree. For incomplete AX/UIA data, use native or vision and include the OS, target application, and observation output in bug reports.
| Symptom | Likely cause | Action |
|---|---|---|
cua-driver not found |
Driver is not in PATH or the official installer path is unavailable |
Install it, confirm ~/.cua-driver/packages/current/cua-driver.exe exists, or set CUA_DRIVER_BIN |
| No visible windows | Missing graphical session or permission | Confirm the target app is visible and observe again |
| Snapshot expired | ttlMs elapsed |
Call screen_observe again |
| Element click failed | The UI changed | Observe again and use the new index |
| Empty AX/UIA tree | Canvas, game, Electron, or special window | Use native or vision |
native rejected |
Main route is not image-capable | Switch to an image-capable model or use vision |
| Vision model unavailable | Provider/model lacks image input declaration | Configure visionProvider / visionModel |
| GLM fallback unavailable | Missing ZHIPU_API_KEY or rate limit |
Configure the key or use a Harness vision model |
background_unavailable |
Driver cannot deliver keyboard/text in the background | Approve the one-time foreground retry if changing window focus is acceptable |
| Risky action rejected | User approval was not granted | Follow the approval result; do not bypass the guard |
| Windows elevated window rejected | Target has a higher privilege level | Use a regular-user window |
