feat: enable Computer Use with macOS + Windows + Linux support
Phase 1: Replace @ant/computer-use-mcp stub (12 files, 6517 lines). Phase 2: Remove 8 macOS-only guards in src/: - main.tsx: remove getPlatform()==='macos' check - swiftLoader.ts: remove darwin-only throw - executor.ts: extend platform guard, clipboard dispatch, paste key - drainRunLoop.ts: skip CFRunLoop pump on non-darwin - escHotkey.ts: non-darwin returns false (Ctrl+C fallback) - hostAdapter.ts: non-darwin permissions granted - common.ts: dynamic platform + screenshotFiltering - gates.ts: enabled:true, subscription check removed Phase 3: Add Linux backends (xdotool/scrot/xrandr/wmctrl): - computer-use-input/backends/linux.ts (173 lines) - computer-use-swift/backends/linux.ts (278 lines) Verified on Windows x64: mouse, screenshot, displays, foreground app. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

# Computer Use — macOS / Windows / Linux 跨平台实施计划
|
||||
|
||||
更新时间:2026-04-03
|
||||
参考项目:`E:\源码\claude-code-source-main\claude-code-source-main`
|
||||
|
||||
## 1. 现状
|
||||
|
||||
参考项目的 Computer Use **仅支持 macOS**——从入口到底层全部写死 darwin。我们的项目在 Phase 1-3 中已经完成了:
|
||||
|
||||
- ✅ `@ant/computer-use-mcp` stub 替换为完整实现(12 文件)
|
||||
- ✅ `@ant/computer-use-input` 拆为 dispatcher + backends(darwin + win32)
|
||||
- ✅ `@ant/computer-use-swift` 拆为 dispatcher + backends(darwin + win32)
|
||||
- ✅ `CHICAGO_MCP` 编译开关已开
|
||||
- ❌ `src/` 层有 6 处 macOS 硬编码阻塞
|
||||
|
||||
## 2. 阻塞点全景
|
||||
|
||||
### 2.1 入口层
|
||||
|
||||
| # | 文件:行号 | 阻塞代码 | 影响 |
|
||||
|---|----------|---------|------|
|
||||
| 1 | `src/main.tsx:1605` | `getPlatform() === 'macos'` | 整个 CU 初始化被跳过 |
|
||||
|
||||
### 2.2 加载层
|
||||
|
||||
| # | 文件:行号 | 阻塞代码 | 影响 |
|
||||
|---|----------|---------|------|
|
||||
| 2 | `src/utils/computerUse/swiftLoader.ts:16` | `process.platform !== 'darwin'` → throw | 截图、应用管理全部不可用 |
|
||||
| 3 | `src/utils/computerUse/executor.ts:263` | `process.platform !== 'darwin'` → throw | 整个 executor 工厂函数不可用 |
|
||||
|
||||
### 2.3 macOS 特有依赖
|
||||
|
||||
| # | 文件:行号 | 依赖 | macOS 实现 | 需要替代方案 |
|
||||
|---|----------|------|-----------|------------|
|
||||
| 4 | `executor.ts:70-88` | 剪贴板 | `pbcopy`/`pbpaste` | Win: PowerShell `Get/Set-Clipboard`;Linux: `xclip`/`wl-copy` |
|
||||
| 5 | `drainRunLoop.ts:21` | CFRunLoop pump | `cu._drainMainRunLoop()` | 非 darwin:直接执行 fn(),不需要 pump |
|
||||
| 6 | `escHotkey.ts:28` | ESC 热键 | CGEventTap | 非 darwin:返回 false(已有 Ctrl+C fallback) |
|
||||
| 7 | `hostAdapter.ts:48-54` | 系统权限 | TCC accessibility + screenRecording | Win:直接 granted;Linux:检查 xdotool |
|
||||
| 8 | `common.ts:56` | 平台标识 | `platform: 'darwin'` 硬编码 | 动态获取 |
|
||||
| 9 | `executor.ts:180` | 粘贴快捷键 | `command+v` | Win/Linux:`ctrl+v` |
|
||||
|
||||
### 2.4 缺失的 Linux 后端
|
||||
|
||||
| 包 | macOS | Windows | Linux |
|
||||
|---|-------|---------|-------|
|
||||
| `computer-use-input/backends/` | ✅ darwin.ts | ✅ win32.ts | ❌ 需新建 linux.ts |
|
||||
| `computer-use-swift/backends/` | ✅ darwin.ts | ✅ win32.ts | ❌ 需新建 linux.ts |
|
||||
|
||||
## 3. 每个平台的能力依赖
|
||||
|

## 4. 执行步骤
|
||||
|
||||
### Phase 1:已完成 ✅
|
||||
|
||||
- [x] `@ant/computer-use-mcp` stub → 完整实现
|
||||
- [x] `@ant/computer-use-input` dispatcher + darwin/win32 backends
|
||||
- [x] `@ant/computer-use-swift` dispatcher + darwin/win32 backends
|
||||
- [x] `CHICAGO_MCP` 编译开关
|
||||
|
||||
### Phase 2:移除 6 处 macOS 硬编码(解锁 macOS + Windows)
|
||||
|
||||
**改动原则:macOS 代码路径不变,只在每处 darwin 守卫后加 win32/linux 分支。**
|
||||
|
||||
| 步骤 | 文件 | 改动 |
|
||||
|------|------|------|
|
||||
| 2.1 | `src/main.tsx:1605` | `getPlatform() === 'macos'` → 去掉平台限制,或改为 `!== 'unknown'` |
|
||||
| 2.2 | `src/utils/computerUse/swiftLoader.ts:16-18` | 移除 `process.platform !== 'darwin'` throw。`@ant/computer-use-swift/index.ts` 已有跨平台 dispatch |
|
||||
| 2.3 | `src/utils/computerUse/executor.ts:263-267` | 移除 `process.platform !== 'darwin'` throw。改为检查 input/swift isSupported |
|
||||
| 2.4 | `src/utils/computerUse/executor.ts:70-88` | 剪贴板函数按平台分发:darwin→pbcopy/pbpaste,win32→PowerShell Get/Set-Clipboard,linux→xclip |
|
||||
| 2.5 | `src/utils/computerUse/executor.ts:180` | `typeViaClipboard` 中 `command+v` → 非 darwin 时用 `ctrl+v` |
|
||||
| 2.6 | `src/utils/computerUse/executor.ts:273` | `const cu = requireComputerUseSwift()` → 改为 `new ComputerUseAPI()`(从 package 直接实例化,不走 swiftLoader throw) |
|
||||
| 2.7 | `src/utils/computerUse/drainRunLoop.ts` | 开头加 `if (process.platform !== 'darwin') return fn()` |
|
||||
| 2.8 | `src/utils/computerUse/escHotkey.ts` | `registerEscHotkey` 非 darwin 返回 false(已有 Ctrl+C fallback) |
|
||||
| 2.9 | `src/utils/computerUse/hostAdapter.ts:48-54` | `ensureOsPermissions` 非 darwin 返回 `{ granted: true }` |
|
||||
| 2.10 | `src/utils/computerUse/common.ts:56` | `platform: 'darwin'` → `platform: process.platform === 'win32' ? 'windows' : process.platform === 'linux' ? 'linux' : 'darwin'` |
|
||||
| 2.11 | `src/utils/computerUse/common.ts:55` | `screenshotFiltering: 'native'` → 非 darwin 时 `'none'`(Windows/Linux 截图不支持 per-app 过滤) |
|
||||
| 2.12 | `src/utils/computerUse/gates.ts:13` | `enabled: false` → `enabled: true`(无 GrowthBook 时默认可用) |
|
||||
| 2.13 | `src/utils/computerUse/gates.ts:39-43` | `hasRequiredSubscription()` → 直接返回 `true` |
|
||||
|
||||
### Phase 3:新增 Linux 后端
|
||||
|
||||
| 步骤 | 文件 | 内容 |
|
||||
|------|------|------|
|
||||
| 3.1 | `packages/@ant/computer-use-input/src/backends/linux.ts` | xdotool 键鼠(mousemove/click/key/type/getactivewindow) |
|
||||
| 3.2 | `packages/@ant/computer-use-swift/src/backends/linux.ts` | scrot/grim 截图 + xrandr 显示器 + wmctrl 窗口管理 |
|
||||
| 3.3 | `packages/@ant/computer-use-input/src/index.ts` | dispatcher 加 `case 'linux'` |
|
||||
| 3.4 | `packages/@ant/computer-use-swift/src/index.ts` | dispatcher 加 `case 'linux'` |
|
||||
|
||||
### Phase 4:验证
|
||||
|
||||
| 测试项 | macOS | Windows | Linux |
|
||||
|--------|-------|---------|-------|
|
||||
| build 成功 | ✅ | 验证 | 验证 |
|
||||
| MCP 工具列表非空 | 验证 | 验证 | 验证 |
|
||||
| 鼠标移动 | 验证 | ✅ 已通过 | 验证 |
|
||||
| 截图 | 验证 | ✅ 已通过 | 验证 |
|
||||
| 键盘输入 | 验证 | 验证 | 验证 |
|
||||
| 前台窗口 | 验证 | ✅ 已通过 | 验证 |
|
||||
| 剪贴板 | 验证 | 验证 | 验证 |
|
||||
|
||||
## 5. 文件改动总览
|
||||
|
||||
### 不动的文件(14 个)
|
||||
|
||||
`cleanup.ts`、`computerUseLock.ts`、`wrapper.tsx`、`toolRendering.tsx`、`mcpServer.ts`、`setup.ts`、`appNames.ts`、`inputLoader.ts`、`src/services/mcp/client.ts`、`@ant/computer-use-mcp/src/*`(Phase 1 已完成)、`backends/darwin.ts`(两个包都不动)
|
||||
|
||||
### 改 src/ 的文件(8 个)
|
||||
|
||||
| 文件 | 改动量 | 风险 |
|
||||
|------|--------|------|
|
||||
| `main.tsx` | 1 行 | 低 |
|
||||
| `swiftLoader.ts` | 2 行 | 低 |
|
||||
| `executor.ts` | ~40 行(剪贴板分发 + 平台守卫 + paste 快捷键) | **中** |
|
||||
| `drainRunLoop.ts` | 1 行 | 低 |
|
||||
| `escHotkey.ts` | 3 行 | 低 |
|
||||
| `hostAdapter.ts` | 5 行 | 低 |
|
||||
| `common.ts` | 3 行 | 低 |
|
||||
| `gates.ts` | 3 行 | 低 |
|
||||
|
||||
### 新增文件(2 个)
|
||||
|
||||
| 文件 | 行数估算 |
|
||||
|------|---------|
|
||||
| `packages/@ant/computer-use-input/src/backends/linux.ts` | ~150 行 |
|
||||
| `packages/@ant/computer-use-swift/src/backends/linux.ts` | ~200 行 |
|
||||
|
||||
## 6. Linux 依赖工具
|
||||
|
||||
| 工具 | 用途 | 安装命令(Ubuntu) |
|
||||
|------|------|-------------------|
|
||||
| `xdotool` | 键鼠模拟 + 窗口管理 | `sudo apt install xdotool` |
|
||||
| `scrot` 或 `gnome-screenshot` | 截图 | `sudo apt install scrot` |
|
||||
| `xrandr` | 显示器信息 | 通常已预装 |
|
||||
| `xclip` | 剪贴板 | `sudo apt install xclip` |
|
||||
| `wmctrl` | 窗口列表/切换 | `sudo apt install wmctrl` |
|
||||
|
||||
Wayland 环境需要替代工具:`ydotool`(替代 xdotool)、`grim`(替代 scrot)、`wl-clipboard`(替代 xclip)。初期可先只支持 X11,Wayland 标记为 todo。
|
||||
|
||||
