+## 1. Patch Environment Overview
+
+The original Claude Code's Computer Use feature (internal codename **Chicago**) depends on three components that are not publicly available:
+
+| Component | Purpose | Availability |
+|-----------|---------|-------------|
+| `@ant/computer-use-swift` | Screenshots, display enumeration | Anthropic private npm package |
+| `@ant/computer-use-input` | Mouse/keyboard simulation | Anthropic private npm package |
+| GrowthBook remote config | Feature flags, kill switch | Anthropic internal service |
+
+Our approach: **preserve the original MCP tool definitions and security mechanisms, only replace the execution layer and feature flag controls**.
+
+
+
+### What We Changed
+
+```
+Original Claude Code Claude Code Haha (Patched)
+──────────────────── ─────────────────────────
+@ant/computer-use-swift ──replaced──→ Python Bridge (mac_helper.py)
+@ant/computer-use-input ──replaced──→ pyautogui + pyobjc
+GrowthBook feature flags ──bypassed──→ gates.ts hardcoded return true
+Subscription check (Max/Pro) ──bypassed──→ getChicagoEnabled() = true
+Build macro CHICAGO_MCP ──replaced──→ true
+isDefaultDisabledBuiltin ──modified──→ returns false
+```
+
+### What We Kept Intact
+
+- **MCP tool definitions** (24 tools with their schema and parameter validation)
+- **9-layer security gates** (TCC permissions, app allowlist, permission tiers, pixel validation, etc.)
+- **App classification system** (191 bundle IDs categorized with permission mappings)
+- **Session context management** (global lock, screenshot cache, state synchronization)
+- **Keyboard shortcut blocklist** (system-level dangerous operation interception)
+
+### Feature Flag Bypass Details
+
+The original code uses three layers of gating to restrict Computer Use access:
+
+```typescript
+// Original code (simplified)
+function getChicagoEnabled(): boolean {
+ // Layer 1: GrowthBook remote config
+ const config = getDynamicConfig('tengu_malort_pedway')
+ // Layer 2: Subscription check
+ const hasSubscription = hasRequiredSubscription() // Max/Pro
+ // Layer 3: Build-time macro
+ return feature('CHICAGO_MCP') && config.enabled && hasSubscription
+}
+```
+
+Our modification:
+
+```typescript
+// gates.ts — our change
+export function getChicagoEnabled(): boolean {
+ return true // ← all three gate layers bypassed
+}
+```
+
+**Note**: Sub-gates (pixelValidation, mouseAnimation, etc.) still retain the original logic and can be controlled via configuration.
+
+---
+
+## 2. Layered Architecture
+
+Computer Use uses a **6-layer architecture** with clear responsibilities and boundaries:
+
+```
+┌─────────────────────────────────────────────────────────────┐
+│ Layer 1 — MCP Tool Interface │
+│ tools.ts: 24 tool schemas + parameter validation │
+│ buildComputerUseTools() → MCP Tool Definition │
+├─────────────────────────────────────────────────────────────┤
+│ Layer 2 — Tool Dispatch & Security Control │
+│ toolCalls.ts: handleToolCall() + 9 security gates │
+│ deniedApps.ts: 191 app classifications + permission tiers │
+├─────────────────────────────────────────────────────────────┤
+│ Layer 3 — MCP Server Binding │
+│ mcpServer.ts: session context + global lock + screenshot │
+│ bindSessionContext() → per-call overrides │
+├─────────────────────────────────────────────────────────────┤
+│ Layer 4 — CLI Integration │
+│ wrapper.tsx: permission dialogs + state read/write │
+│ setup.ts: MCP config initialization │
+│ gates.ts: feature flags (bypassed) │
+├─────────────────────────────────────────────────────────────┤
+│ Layer 5 — Python Bridge IPC [PATCH] │
+│ pythonBridge.ts: venv mgmt + JSON RPC + error handling │
+│ callPythonHelper(command, payload) → T │
+├─────────────────────────────────────────────────────────────┤
+│ Layer 6 — Python Runtime Execution [PATCH] │
+│ mac_helper.py: pyautogui + mss + pyobjc │
+│ 660 lines of Python implementing all system interactions │
+└─────────────────────────────────────────────────────────────┘
+```
+
+Layers marked **[PATCH]** are our replaced/new code. **All other layers** are preserved from the original Claude Code.
+
+### Why This Layering?
+
+| Layer | Source | Reusability |
+|-------|--------|------------|
+| Layer 1-2 | `vendor/computer-use-mcp/` | Platform-agnostic, reusable for Electron, Web hosts |
+| Layer 3 | `vendor/computer-use-mcp/` | Platform-agnostic, standard MCP protocol |
+| Layer 4 | `utils/computerUse/` | CLI-specific, bound to app state |
+| Layer 5-6 | `utils/computerUse/` + `runtime/` | macOS-specific, Python implementation |
+
+---
+
+## 3. MCP Tool Layer
+
+### 24 Tools Overview
+
+Computer Use exposes 24 tools to the model via MCP (Model Context Protocol):
+
+| Category | Tools | Permission Tier |
+|----------|-------|----------------|
+| **Permission** | `request_access`, `list_granted_applications` | None required |
+| **Screenshot** | `screenshot`, `zoom` | read |
+| **Mouse Click** | `left_click`, `double_click`, `triple_click` | click |
+| **Mouse Advanced** | `right_click`, `middle_click`, `left_click_drag` | full |
+| **Mouse Move** | `mouse_move`, `cursor_position`, `scroll` | click |
+| **Mouse Low-level** | `left_mouse_down`, `left_mouse_up` | full |
+| **Keyboard** | `type`, `key`, `hold_key` | full |
+| **Application** | `open_application`, `switch_display` | full |
+| **Clipboard** | `read_clipboard`, `write_clipboard` | full |
+| **Batch** | `computer_batch` | Inherits from sub-operations |
+| **Wait** | `wait` | None required |
+
+### Coordinate System
+
+The model interacts with the screen through two coordinate modes:
+
+```
+pixels mode (default):
+ Model sees screenshot size (1176 x 784)
+ Model outputs coordinate [588, 392]
+ scaleCoord() conversion:
+ x_logical = (588 * displayWidth / 1176) + originX
+ y_logical = (392 * displayHeight / 784) + originY
+
+normalized_0_100 mode:
+ Model outputs coordinate [50, 50] (percentage)
+ scaleCoord() conversion:
+ x_logical = (50 / 100) * displayWidth + originX
+ y_logical = (50 / 100) * displayHeight + originY
+```
+
+Screenshot dimensions are calculated by `imageResize.ts` to ensure:
+- Long edge <= 1568 pixels
+- Token budget <= 1568 (vision encoder at 28px/token)
+- Aspect ratio preserved
+
+### App Classification System
+
+`deniedApps.ts` precisely classifies 191 applications:
+
+**Browsers** (55 bundle IDs) -> tier `read`
+```
+Safari, Chrome, Firefox, Arc, Edge, Opera, Brave, Vivaldi...
+Reason: browser operations should use Chrome MCP, not blind clicking
+```
+
+**Terminals** (102 bundle IDs) -> tier `click`
+```
+Terminal, iTerm2, VS Code, Cursor, JetBrains IDEs, Xcode...
+Reason: terminal operations should use Bash Tool, limited to click only
+```
+
+**Trading** (34 bundle IDs) -> tier `read`
+```
+Webull, Fidelity, Interactive Brokers, Binance, Kraken...
+Reason: financial operations are extremely high-risk, screenshot only
+```
+
+**Completely Blocked** (policy deny list):
+```
+Netflix, Spotify, Apple Music, Kindle...
+Reason: copyright compliance, rejected without permission dialog
+```
+
+---
+
+## 4. Security Gate System
+
+Every input action (click, keyboard, drag) must pass through **9 security gates** before execution:
+
+
+
+### Gate Details
+
+#### Gate 1: Kill Switch
+```typescript
+if (adapter.isDisabled()) return errorResult("Computer Use is disabled")
+```
+Reads `getChicagoEnabled()` — always returns `true` in patched version.
+
+#### Gate 2: TCC Permission Check
+```typescript
+await adapter.ensureOsPermissions()
+// → Python: check_permissions
+// → Accessibility: osascript "tell System Events..."
+// → Screen Recording: CGDisplayCaptureDisplay()
+```
+Reports error if macOS Accessibility or Screen Recording permissions are missing.
+
+#### Gate 3: Global Mutex Lock
+```typescript
+await tryAcquireComputerUseLock(sessionId)
+// File lock: ~/.claude/computer-use.lock
+// JSON: { sessionId, pid, acquiredAt }
+```
+Ensures only one Claude session can control the computer at a time. Supports stale PID recovery.
+
+#### Gate 4: Hide Non-Allowlisted Apps
+```typescript
+await executor.prepareForAction(allowlistBundleIds)
+// Hide all app windows not in the allowlist
+// Ensures screenshots only contain authorized apps
+```
+
+#### Gate 5: Frontmost App Check
+```typescript
+const frontmost = await executor.getFrontmostApp()
+if (!allowlist.includes(frontmost.bundleId)) {
+ return errorResult("Application not authorized")
+}
+```
+Even after passing the allowlist, verifies the current foreground app is authorized.
+
+#### Gate 6: Permission Tier Check
+
+Three-tier permission model:
+
+| Tier | Allowed Operations | Prohibited Operations |
+|------|-------------------|----------------------|
+| `read` | Screenshot viewing | Any input action |
+| `click` | Left click, scroll | Right-click, drag, keyboard input |
+| `full` | All operations | No restrictions |
+
+```typescript
+function tierSatisfies(tier: CuAppPermTier, required: ActionKind): boolean {
+ const order = { read: 0, click: 1, full: 2 }
+ return order[tier] >= order[required]
+}
+```
+
+**Anti-subversion**: If permissions are insufficient, the response includes a `TIER_ANTI_SUBVERSION` hint to prevent the model from bypassing restrictions via AppleScript or System Events.
+
+#### Gate 7: Clipboard Guard
+
+**Threat model**:
+```
+1. Agent calls write_clipboard("rm -rf /")
+2. Switches to Terminal (click-tier allows clicking)
+3. Model clicks Terminal's paste button
+4. Malicious command executed
+```
+
+**Protection**:
+```
+When click-tier app becomes frontmost:
+ → Save current clipboard content (stash)
+ → Clear clipboard
+ → Re-clear after each operation
+
+When non-click-tier app becomes frontmost:
+ → Restore original clipboard content
+```
+
+#### Gate 8: Pixel Validation (Staleness Guard)
+
+```
+Last screenshot Current actual screen
+┌────────────┐ ┌────────────┐
+│ Button A │ │ Dialog │ ← UI has changed
+│ [756,342] │ │ Confirm? │
+└────────────┘ └────────────┘
+
+Validation: sample 9x9 pixel grid at [756,342]
+ → Compare last screenshot vs live screenshot pixels
+ → Different → reject click + prompt to re-screenshot
+ → Same → allow click
+```
+
+**Note**: In patched version, `pixelValidation` is off by default (`hostAdapter.cropRawPatch()` returns null).
+
+#### Gate 9: System Shortcut Interception
+
+`keyBlocklist.ts` blocks dangerous shortcuts:
+
+| Shortcut | Dangerous Action |
+|----------|-----------------|
+| `Cmd+Q` | Quit application |
+| `Shift+Cmd+Q` | Log out |
+| `Option+Cmd+Esc` | Force quit dialog |
+| `Cmd+Tab` | App switcher |
+| `Cmd+Space` | Spotlight |
+| `Ctrl+Cmd+Q` | Lock screen |
+
+---
+
+## 5. Python Bridge Mechanism
+
+
+
+### Architecture Design
+
+Original Claude Code uses compiled Swift native modules (.node NAPI plugins) to directly call macOS APIs. We replaced this layer with **Python subprocess + JSON RPC**:
+
+```
+TypeScript (Bun Runtime) Python (venv)
+┌────────────────────┐ ┌────────────────────┐
+│ executor.ts │ │ mac_helper.py │
+│ │ execFile() │ │
+│ callPythonHelper │ ──────────────→ │ main() │
+│ ('click', │ command + │ ├─ parse argv │
+│ {x:756,y:342}) │ --payload JSON │ ├─ dispatch() │
+│ │ │ └─ click() │
+│ ← JSON.parse ──── │ ←────────────── │ pyautogui │
+│ {ok:true, │ stdout JSON │ │
+│ result:true} │ │ json_output(...) │
+└────────────────────┘ └────────────────────┘
+```
+
+### Bootstrap Flow
+
+First call to `callPythonHelper()` automatically completes environment setup:
+
+```
+ensureBootstrapped()
+ │
+ ├─ Check if .runtime/venv/bin/python3 exists
+ │ └─ Missing → python3 -m venv .runtime/venv/
+ │
+ ├─ Check if pip is available
+ │ └─ Missing → python3 -m ensurepip --upgrade
+ │
+ ├─ Compute SHA256 of runtime/requirements.txt
+ │ └─ Compare with .runtime/requirements.sha256
+ │ └─ Different → pip install -r requirements.txt
+ │ Write new SHA256 hash
+ │ └─ Same → skip installation
+ │
+ └─ Ready, return venv Python path
+```
+
+**Dependencies** (`runtime/requirements.txt`):
+
+| Library | Purpose |
+|---------|---------|
+| `mss` | High-performance screen capture |
+| `Pillow` | JPEG encoding and image processing |
+| `pyautogui` | Mouse click, keyboard input |
+| `pyobjc-core` | macOS Objective-C bridge |
+| `pyobjc-framework-Cocoa` | NSWorkspace (app management), NSPasteboard (clipboard) |
+| `pyobjc-framework-Quartz` | CGDisplay (monitors), CGWindow (window list) |
+
+### Command Mapping
+
+`mac_helper.py` (660 lines) implements the following commands:
+
+| Command | Python Implementation | Return Value |
+|---------|----------------------|-------------|
+| `screenshot` | `mss.grab()` + `PIL.Image` JPEG encoding | `{base64, width, height, displayWidth, displayHeight}` |
+| `zoom` | `mss.grab(region)` region capture | `{base64, width, height}` |
+| `click` | `pyautogui.moveTo()` + `pyautogui.click()` | `true` |
+| `key` | `pyautogui.hotkey()` / `pyautogui.press()` | `true` |
+| `type` | `pyautogui.write(interval=0.008)` | `true` |
+| `drag` | `pyautogui.dragTo(duration=0.2)` | `true` |
+| `scroll` | `pyautogui.scroll()` / `pyautogui.hscroll()` | `true` |
+| `hold_key` | `pyautogui.keyDown()` + `sleep` + `pyautogui.keyUp()` | `true` |
+| `frontmost_app` | `NSWorkspace.frontmostApplication()` | `{bundleId, displayName}` |
+| `list_displays` | `CGGetActiveDisplayList()` + `CGDisplayBounds()` | `[DisplayGeometry...]` |
+| `open_app` | `NSWorkspace.launchApplicationAtURL_options_` | `void` |
+| `read_clipboard` | `NSPasteboard.stringForType_()` | `string` |
+| `write_clipboard` | `NSPasteboard.setString_forType_()` | `void` |
+| `check_permissions` | `osascript` + `CGDisplayCaptureDisplay` | `{accessibility, screenRecording}` |
+
+### Error Handling
+
+```python
+# mac_helper.py unified error handling
+def main():
+ try:
+ result = dispatch(command, payload)
+ json_output({"ok": True, "result": result})
+ except Exception as e:
+ error_output({"ok": False, "error": {"message": str(e)}})
+```
+
+TypeScript side:
+```typescript
+// pythonBridge.ts
+const parsed = JSON.parse(stdout)
+if (!parsed.ok) {
+ throw new Error(parsed.error.message) // → MCP tool error
+}
+return parsed.result
+```
+
+---
+
+## 6. Screenshot-Analyze-Act Loop
+
+A complete Computer Use interaction consists of multiple **screenshot-analyze-act** cycles:
+
+### Typical Interaction Flow
+
+```

+
+### Coordinate Conversion
+
+**What the model sees** vs **actual screen** are different coordinate spaces:
+
+```
+Physical screen (2560 x 1600, Retina 2x)
+ ├─ Logical size: 1280 x 800
+ └─ Physical pixels: 2560 x 1600
+
+After imageResize:
+ ├─ Scaled size: 1176 x 735 (≤1568px budget)
+ └─ This is the screenshot size the model "sees"
+
+Model outputs coordinate: [588, 368] (in image space)
+
+scaleCoord conversion:
+ x_logical = (588 / 1176) * 1280 + originX = 640
+ y_logical = (368 / 735) * 800 + originY = 400
+
+Python executes:
+ pyautogui.moveTo(640, 400) ← logical coords (macOS handles Retina)
+```
+
+### Screenshot Cache & State Sync
+
+```
+bindSessionContext closure
+ │
+ ├─ lastScreenshot (in-memory)
+ │ ├─ base64: JPEG data (for pixel validation)
+ │ ├─ width/height: model-visible dimensions
+ │ └─ displayWidth/displayHeight/originX/originY: display geometry
+ │
+ └─ AppState.computerUseMcpState (persisted)
+ ├─ allowedApps: AppGrant[] — authorized app list
+ ├─ grantFlags: {...} — clipboard/system shortcut permissions
+ ├─ selectedDisplayId?: number — selected display
+ ├─ lastScreenshotDims?: {...} — screenshot geometry (survives restart)
+ └─ hiddenDuringTurn?: Set — apps hidden this turn

+
+## 8. Design Trade-offs
+
+### Why Python Bridge?
+
+| Dimension | Native Swift (.node) | Python Bridge |
+|-----------|---------------------|---------------|
+| **Performance** | ~0ms (in-process call) | ~50-100ms (subprocess startup) |
+| **Readability** | Not readable after compilation | 660 lines of clear Python |
+| **Modifiability** | Requires Swift build environment | Edit .py files directly |
+| **Dependencies** | Specific Bun version NAPI | Any Python 3.8+ |
+| **Cross-platform** | macOS only | pyautogui/mss are natively cross-platform |
+| **User experience** | Imperceptible | Imperceptible (model thinking takes 2-5s) |
+
+**Conclusion**: The 50-100ms extra latency is completely negligible in Computer Use scenarios — the model typically takes 2-5 seconds for screenshot analysis and decision-making, so users won't notice the additional 100ms for underlying operations.
+
+### Approaches We Tried But Abandoned
+
+**Approach 1: Extract native .node modules**
+- Successfully extracted `computer-use-swift.node` (ARM64 424KB) from the Claude Code binary
+- Synchronous methods worked, but **Swift async method continuations never resumed**
+- Root cause: .node files compiled for Claude Code's built-in Bun, incompatible with user's Bun version
+
+**Approach 2: Empty stub packages**
+- Code compiled but all operations threw errors — no actual execution capability

+
+---
+
+## 一、补丁环境总览
+
+Claude Code 原版的 Computer Use 功能(内部代号 **Chicago**)依赖三个不可公开获取的组件:
+
+| 组件 | 作用 | 获取方式 |
+|------|------|----------|
+| `@ant/computer-use-swift` | 屏幕截图、显示器枚举 | Anthropic 私有 npm 包 |
+| `@ant/computer-use-input` | 鼠标/键盘模拟 | Anthropic 私有 npm 包 |
+| GrowthBook 远程配置 | 灰度控制、功能开关 | Anthropic 内部服务 |
+
+我们的方案是:**保留原始 MCP 工具定义和安全机制不变,仅替换底层执行层和灰度控制**。
+
+
+
+### 我们做了什么
+
+```
+原始 Claude Code Claude Code Haha (补丁版)
+───────────────── ─────────────────────────
+@ant/computer-use-swift ──替换为──→ Python Bridge (mac_helper.py)
+@ant/computer-use-input ──替换为──→ pyautogui + pyobjc
+GrowthBook 灰度控制 ──绕过──→ gates.ts 硬编码 return true
+订阅检查 (Max/Pro) ──绕过──→ getChicagoEnabled() = true
+编译宏 CHICAGO_MCP ──替换为──→ true
+isDefaultDisabledBuiltin ──修改──→ 返回 false
+```
+
+### 我们没有改什么
+
+- **MCP 工具定义**(24 个工具的 schema 和参数校验)
+- **9 层安全关卡**(TCC 权限、应用白名单、权限等级、像素验证等)
+- **应用分类系统**(191 个 bundle ID 的分类和权限映射)
+- **会话上下文管理**(全局锁、截图缓存、状态同步)
+- **键盘快捷键阻止列表**(系统级危险操作拦截)
+
+### 灰度绕过细节
+
+原始代码通过三层门控限制 Computer Use 的访问:
+
+```typescript
+// 原始代码(简化)
+function getChicagoEnabled(): boolean {
+ // 层1:GrowthBook 远程配置
+ const config = getDynamicConfig('tengu_malort_pedway')
+ // 层2:订阅检查
+ const hasSubscription = hasRequiredSubscription() // Max/Pro
+ // 层3:编译时宏
+ return feature('CHICAGO_MCP') && config.enabled && hasSubscription
+}
+```
+
+我们的处理:
+
+```typescript
+// gates.ts — 我们的修改
+export function getChicagoEnabled(): boolean {
+ return true // ← 三层门控全部绕过
+}
+```
+
+**注意**:子开关(pixelValidation、mouseAnimation 等)仍然保留原始逻辑,可通过配置控制。
+
+---
+
+## 二、分层架构
+
+Computer Use 采用 **6 层架构**,每层职责清晰、边界明确:
+
+```
+┌─────────────────────────────────────────────────────────────┐
+│ Layer 1 — MCP 工具接口层 │
+│ tools.ts: 24 个工具 schema + 参数校验 │
+│ buildComputerUseTools() → MCP Tool Definition │
+├─────────────────────────────────────────────────────────────┤
+│ Layer 2 — 工具调度与安全控制层 │
+│ toolCalls.ts: handleToolCall() + 9 层安全关卡 │
+│ deniedApps.ts: 191 个应用分类 + 权限等级 │
+├─────────────────────────────────────────────────────────────┤
+│ Layer 3 — MCP 服务器绑定层 │
+│ mcpServer.ts: 会话上下文 + 全局锁 + 截图缓存 │
+│ bindSessionContext() → per-call overrides │
+├─────────────────────────────────────────────────────────────┤
+│ Layer 4 — CLI 集成层 │
+│ wrapper.tsx: 权限对话框 + 状态读写 │
+│ setup.ts: MCP 配置初始化 │
+│ gates.ts: 灰度控制(已绕过) │
+├─────────────────────────────────────────────────────────────┤
+│ Layer 5 — Python Bridge 进程通信层 [补丁] │
+│ pythonBridge.ts: venv 管理 + JSON RPC + 错误处理 │
+│ callPythonHelper(command, payload) → T │
+├─────────────────────────────────────────────────────────────┤
+│ Layer 6 — Python 运行时执行层 [补丁] │
+│ mac_helper.py: pyautogui + mss + pyobjc │
+│ 660 行 Python 实现所有系统交互 │
+└─────────────────────────────────────────────────────────────┘
+```
+
+**标 `[补丁]` 的层**是我们替换/新增的代码,**其余层完全保留**原始 Claude Code 的逻辑。
+
+### 为什么这样分层?
+
+| 层 | 来源 | 可复用性 |
+|----|------|----------|
+| Layer 1-2 | `vendor/computer-use-mcp/` | 平台无关,可用于 Electron、Web 等宿主 |
+| Layer 3 | `vendor/computer-use-mcp/` | 平台无关,MCP 标准协议 |
+| Layer 4 | `utils/computerUse/` | CLI 专用,绑定应用状态 |
+| Layer 5-6 | `utils/computerUse/` + `runtime/` | macOS 专用,Python 实现 |
+
+---
+
+## 三、MCP 工具层
+
+### 24 个工具一览
+
+Computer Use 通过 MCP(Model Context Protocol)暴露 24 个工具给模型:
+
+| 类别 | 工具 | 权限等级 |
+|------|------|----------|
+| **权限** | `request_access`, `list_granted_applications` | 无需权限 |
+| **截屏** | `screenshot`, `zoom` | read |
+| **鼠标点击** | `left_click`, `double_click`, `triple_click` | click |
+| **鼠标高级** | `right_click`, `middle_click`, `left_click_drag` | full |
+| **鼠标移动** | `mouse_move`, `cursor_position`, `scroll` | click |
+| **鼠标底层** | `left_mouse_down`, `left_mouse_up` | full |
+| **键盘** | `type`, `key`, `hold_key` | full |
+| **应用** | `open_application`, `switch_display` | full |
+| **剪贴板** | `read_clipboard`, `write_clipboard` | full |
+| **批量** | `computer_batch` | 继承子操作 |
+| **等待** | `wait` | 无需权限 |
+
+### 坐标系统
+
+模型通过两种坐标模式与屏幕交互:
+
+```
+pixels 模式(默认):
+ 模型看到截图尺寸 (1176 x 784)
+ 模型输出坐标 [588, 392]
+ scaleCoord() 转换:
+ x_logical = (588 * displayWidth / 1176) + originX
+ y_logical = (392 * displayHeight / 784) + originY
+
+normalized_0_100 模式:
+ 模型输出坐标 [50, 50](百分比)
+ scaleCoord() 转换:
+ x_logical = (50 / 100) * displayWidth + originX
+ y_logical = (50 / 100) * displayHeight + originY
+```
+
+截图尺寸经过 `imageResize.ts` 计算,确保:
+- 长边 ≤ 1568 像素
+- Token 预算 ≤ 1568(视觉编码器 28px/token)
+- 保持宽高比
+
+### 应用分类系统
+
+`deniedApps.ts` 对 191 个应用进行精细分类:
+
+**浏览器类**(55 个 bundle ID)→ 权限等级 `read`
+```
+Safari, Chrome, Firefox, Arc, Edge, Opera, Brave, Vivaldi...
+理由:浏览器操作应使用 Chrome MCP,而非盲点击
+```
+
+**终端类**(102 个 bundle ID)→ 权限等级 `click`
+```
+Terminal, iTerm2, VS Code, Cursor, JetBrains 全家桶, Xcode...
+理由:终端操作应使用 Bash Tool,限制为只能点击不能输入
+```
+
+**交易类**(34 个 bundle ID)→ 权限等级 `read`
+```
+Webull, Fidelity, Interactive Brokers, Binance, Kraken...
+理由:金融操作风险极高,仅允许截图查看
+```
+
+**完全禁止**(策略拒绝名单):
+```
+Netflix, Spotify, Apple Music, Kindle...
+理由:版权合规,不进入权限对话框直接拒绝
+```
+
+---
+
+## 四、安全关卡体系
+
+每个输入操作(点击、键盘、拖拽)在执行前需通过 **9 层安全关卡**:
+
+
+
+### 关卡详解
+
+#### Gate 1:Kill Switch
+```typescript
+if (adapter.isDisabled()) return errorResult("Computer Use is disabled")
+```
+读取 `getChicagoEnabled()` — 在补丁版中永远返回 `true`。
+
+#### Gate 2:TCC 权限检查
+```typescript
+await adapter.ensureOsPermissions()
+// → Python: check_permissions
+// → Accessibility: osascript "tell System Events..."
+// → Screen Recording: CGDisplayCaptureDisplay()
+```
+如果缺少 macOS Accessibility 或 Screen Recording 权限,直接报错。
+
+#### Gate 3:全局互斥锁
+```typescript
+await tryAcquireComputerUseLock(sessionId)
+// 文件锁: ~/.claude/computer-use.lock
+// JSON: { sessionId, pid, acquiredAt }
+```
+确保同一时间只有一个 Claude 会话可以控制电脑。支持 stale PID 恢复。
+
+#### Gate 4:隐藏非白名单应用
+```typescript
+await executor.prepareForAction(allowlistBundleIds)
+// 隐藏所有不在白名单中的应用窗口
+// 确保截图中只出现授权应用
+```
+
+#### Gate 5:前台应用检查
+```typescript
+const frontmost = await executor.getFrontmostApp()
+if (!allowlist.includes(frontmost.bundleId)) {
+ return errorResult("Application not authorized")
+}
+```
+即使通过了白名单,还需确认当前前台应用是已授权的。
+
+#### Gate 6:权限等级检查
+
+三级权限模型:
+
+| Tier | 允许的操作 | 禁止的操作 |
+|------|-----------|-----------|
+| `read` | 截图查看 | 任何输入操作 |
+| `click` | 左键点击、滚动 | 右键、拖拽、键盘输入 |
+| `full` | 全部操作 | 无限制 |
+
+```typescript
+function tierSatisfies(tier: CuAppPermTier, required: ActionKind): boolean {
+ const order = { read: 0, click: 1, full: 2 }
+ return order[tier] >= order[required]
+}
+```
+
+**反绕过机制**:如果权限不足,响应中会附加 `TIER_ANTI_SUBVERSION` 提示,防止模型通过 AppleScript 或 System Events 绕过限制。
+
+#### Gate 7:剪贴板防护
+
+**威胁模型**:
+```
+1. Agent 调用 write_clipboard("rm -rf /")
+2. 切换到 Terminal(click-tier 允许点击)
+3. 模型点击 Terminal 的粘贴按钮
+4. 恶意命令被执行
+```
+
+**防护机制**:
+```
+当 click-tier 应用成为前台时:
+ → 保存当前剪贴板内容(stash)
+ → 清空剪贴板
+ → 每次操作后再次清空
+
+当非 click-tier 应用成为前台时:
+ → 恢复原始剪贴板内容
+```
+
+#### Gate 8:像素验证(Staleness Guard)
+
+```
+上次截图 当前实际屏幕
+┌────────────┐ ┌────────────┐
+│ 按钮A │ │ 对话框 │ ← UI 已变化
+│ [756,342] │ │ 确认? │
+└────────────┘ └────────────┘
+
+像素验证:在 [756,342] 取 9×9 网格
+ → 对比上次截图 vs 实时截图的像素
+ → 不同 → 拒绝点击 + 提示重新截图
+ → 相同 → 允许点击
+```
+
+**注意**:补丁版中 `pixelValidation` 默认关闭(`hostAdapter.cropRawPatch()` 返回 null)。
+
+#### Gate 9:系统快捷键拦截
+
+`keyBlocklist.ts` 阻止危险快捷键:
+
+| 快捷键 | 危险操作 |
+|--------|---------|
+| `⌘Q` | 退出应用 |
+| `⇧⌘Q` | 登出系统 |
+| `⌥⌘⎋` | 强制退出对话框 |
+| `⌘Tab` | 应用切换器 |
+| `⌘Space` | Spotlight |
+| `⌃⌘Q` | 锁屏 |
+
+---
+
+## 五、Python Bridge 机制
+
+
+
+### 架构设计
+
+原始 Claude Code 使用编译好的 Swift 原生模块(.node NAPI 插件)直接调用 macOS API。我们用 **Python 子进程 + JSON RPC** 替代了这一层:
+
+```
+TypeScript (Bun 运行时) Python (venv)
+┌────────────────────┐ ┌────────────────────┐
+│ executor.ts │ │ mac_helper.py │
+│ │ execFile() │ │
+│ callPythonHelper │ ──────────────→ │ main() │
+│ ('click', │ command + │ ├─ 解析 argv │
+│ {x:756,y:342}) │ --payload JSON │ ├─ dispatch() │
+│ │ │ └─ click() │
+│ ← JSON.parse ──── │ ←────────────── │ pyautogui │
+│ {ok:true, │ stdout JSON │ │
+│ result:true} │ │ json_output(...) │
+└────────────────────┘ └────────────────────┘
+```
+
+### 启动引导流程
+
+首次调用 `callPythonHelper()` 时自动完成环境初始化:
+
+```
+ensureBootstrapped()
+ │
+ ├─ 检查 .runtime/venv/bin/python3 是否存在
+ │ └─ 不存在 → python3 -m venv .runtime/venv/
+ │
+ ├─ 检查 pip 是否可用
+ │ └─ 不可用 → python3 -m ensurepip --upgrade
+ │
+ ├─ 计算 runtime/requirements.txt 的 SHA256
+ │ └─ 与 .runtime/requirements.sha256 对比
+ │ └─ 不同 → pip install -r requirements.txt
+ │ 写入新的 SHA256 哈希
+ │ └─ 相同 → 跳过安装
+ │
+ └─ 就绪,返回 venv Python 路径
+```
+
+**依赖清单**(`runtime/requirements.txt`):
+
+| 库 | 用途 |
+|----|------|
+| `mss` | 高性能屏幕截图 |
+| `Pillow` | JPEG 编码和图像处理 |
+| `pyautogui` | 鼠标点击、键盘输入 |
+| `pyobjc-core` | macOS Objective-C 桥接 |
+| `pyobjc-framework-Cocoa` | NSWorkspace(应用管理)、NSPasteboard(剪贴板) |
+| `pyobjc-framework-Quartz` | CGDisplay(显示器)、CGWindow(窗口列表) |
+
+### 命令映射表
+
+`mac_helper.py`(660 行)实现了以下命令:
+
+| 命令 | Python 实现 | 返回值 |

+### 错误处理
+
+```python
+# mac_helper.py 的统一错误处理
+def main():
+ try:
+ result = dispatch(command, payload)
+ json_output({"ok": True, "result": result})
+ except Exception as e:
+ error_output({"ok": False, "error": {"message": str(e)}})
+```
+
+TypeScript 端:
+```typescript
+// pythonBridge.ts
+const parsed = JSON.parse(stdout)
+if (!parsed.ok) {
+ throw new Error(parsed.error.message) // → MCP tool error
+}
+return parsed.result
+```

+
+## 六、截图-分析-操作闭环
+
+一个完整的 Computer Use 交互由多个 **截图-分析-操作** 循环组成:
+
+### 典型交互流程
+
+```
+用户: "帮我打开网易云音乐,搜索一首歌"
+
+┌─ 循环 1:发现并打开应用 ─────────────────────────────────┐
+│ │
+│ Step 1: request_access │
+│ → 弹出权限对话框,用户授权允许操作的应用 │
+│ → 设置 allowedApps, grantFlags │
+│ │
+│ Step 2: screenshot │
+│ → 截取全屏 → JPEG 编码 → base64 │
+│ → 缓存截图尺寸 (lastScreenshotDims) │
+│ → 返回给模型 │
+│ │
+│ Step 3: 模型分析截图 │
+│ → "桌面上没有网易云音乐,需要打开它" │
+│ → 决定调用 open_application │
+│ │
+│ Step 4: open_application("com.netease.163music") │
+│ → Gate 1-9 全部通过 │
+│ → Python: NSWorkspace.launchApplicationAtURL_() │
+│ │
+└──────────────────────────────────────────────────────────┘
+
+┌─ 循环 2:定位搜索框 ────────────────────────────────────┐
+│ │
+│ Step 5: screenshot │
+│ → 截取全屏(网易云已打开) │
+│ → 更新 lastScreenshotDims │
+│ │
+│ Step 6: 模型分析截图 │
+│ → 视觉识别搜索框位置 → (756, 342) │
+│ → 决定点击搜索框 │
+│ │
+│ Step 7: left_click({coordinate: [756, 342]}) │
+│ → Gate 4: 隐藏非白名单应用 │
+│ → Gate 5: 前台是网易云 ✓ │
+│ → Gate 6: tier=full ≥ click ✓ │
+│ → Gate 7: 非 click-tier 应用,跳过 │
+│ → scaleCoord(756, 342) 转换为屏幕坐标 │
+│ → Python: pyautogui.click(x_logical, y_logical) │
+│ │
+└──────────────────────────────────────────────────────────┘
+
+┌─ 循环 3:输入搜索词 ────────────────────────────────────┐
+│ │
+│ Step 8: type({text: "喜欢你"}) │
+│ → Gate 6: tier=full ≥ keyboard ✓ │
+│ → Python: pyautogui.write("喜欢你", interval=0.008) │
+│ │
+│ Step 9: screenshot │
+│ → 确认搜索结果已出现 │
+│ → 模型分析:"搜索结果列表中第一个就是目标歌曲" │
+│ │
+│ Step 10: left_click({coordinate: [...]}) │
+│ → 点击目标歌曲 │
+│ │
+└──────────────────────────────────────────────────────────┘
+```
+
+### 坐标转换的关键
+
+**模型看到的**和**屏幕实际的**是不同的坐标空间:
+
+```
+原始屏幕 (2560 x 1600, Retina 2x)
+ ├─ 逻辑尺寸: 1280 x 800
+ └─ 物理像素: 2560 x 1600
+
+imageResize 计算后:
+ ├─ 缩放后尺寸: 1176 x 735 (≤1568px 预算)
+ └─ 这就是模型"看到"的截图尺寸
+
+模型输出坐标: [588, 368](图像空间的像素位置)
+
+scaleCoord 转换:
+ x_logical = (588 / 1176) * 1280 + originX = 640 + 0 = 640
+ y_logical = (368 / 735) * 800 + originY = 400 + 0 = 400
+
+Python 执行:
+ pyautogui.moveTo(640, 400) ← 逻辑坐标(macOS 自动处理 Retina)
+```
+
+### 截图缓存与状态同步
+
+```
+bindSessionContext 闭包
+ │
+ ├─ lastScreenshot (内存)
+ │ ├─ base64: JPEG 数据(用于 pixel validation)
+ │ ├─ width/height: 模型看到的尺寸
+ │ └─ displayWidth/displayHeight/originX/originY: 显示器几何
+ │
+ └─ AppState.computerUseMcpState (持久化)
+ ├─ allowedApps: AppGrant[] — 已授权应用列表
+ ├─ grantFlags: {...} — 剪贴板/系统快捷键权限
+ ├─ selectedDisplayId?: number — 选定的显示器
+ ├─ lastScreenshotDims?: {...} — 截图几何(跨重启恢复)
+ └─ hiddenDuringTurn?: Set — 本轮隐藏的应用
+```

+## 七、关键源文件索引
+
+### vendor/computer-use-mcp/(原始代码层)
+
+| 文件 | 行数 | 职责 |
+|------|------|------|
+| `types.ts` | 622 | 权限模型、会话上下文、全部类型定义 |
+| `tools.ts` | 707 | 24 个 MCP 工具的 schema 和参数校验 |
+| `toolCalls.ts` | 1600+ | **核心**:工具派发、9 层安全关卡、权限流程 |
+| `deniedApps.ts` | 554 | 191 个应用的分类(browser/terminal/trading)和权限映射 |
+| `sentinelApps.ts` | 44 | 敏感应用预警标签(shell/filesystem/system_settings) |
+| `mcpServer.ts` | 314 | MCP 服务器工厂、会话上下文绑定、全局锁 |
+| `pixelCompare.ts` | 172 | 点击目标像素验证(staleness guard) |

+| `keyBlocklist.ts` | 154 | 系统快捷键拦截(⌘Q、⌘Tab 等) |
+| `executor.ts` | 101 | ComputerExecutor 接口定义 |
+| `subGates.ts` | 20 | 灰度子开关预设组合 |
+
+### utils/computerUse/(CLI 适配层)
+
+| 文件 | 行数 | 职责 | 补丁? |
+|------|------|------|-------|
+| `executor.ts` | 231 | ComputerExecutor 的 Python bridge 实现 | ✅ 重写 |
+| `pythonBridge.ts` | 111 | Python 子进程管理、venv 引导、JSON RPC | ✅ 新增 |
+| `hostAdapter.ts` | 54 | HostAdapter 实现(权限检查、灰度读取) | 部分修改 |
+| `gates.ts` | 51 | GrowthBook 灰度控制(`getChicagoEnabled` 绕过) | ✅ 修改 |
+| `wrapper.tsx` | 300+ | 会话上下文构建、权限对话框、锁管理 | 未修改 |
+| `setup.ts` | 54 | MCP 配置初始化 | 未修改 |
+| `computerUseLock.ts` | 216 | 全局文件锁(`~/.claude/computer-use.lock`) | 未修改 |
+| `common.ts` | 62 | 常量定义(server name、bundle ID) | 未修改 |
+| `cleanup.ts` | — | turn-end 清理(应用恢复、剪贴板恢复) | 未修改 |
+| `toolRendering.tsx` | — | 工具结果 UI 渲染 | 未修改 |
+
+### runtime/(Python 运行时)
+
+| 文件 | 行数 | 职责 | 补丁? |
+|------|------|------|-------|
+| `mac_helper.py` | 660 | 所有系统交互的 Python 实现 | ✅ 新增 |
+| `requirements.txt` | 6 | Python 依赖声明 | ✅ 新增 |
+
+---
+
+## 八、设计权衡
+
+### 为什么选择 Python Bridge?
+
+| 维度 | 原生 Swift (.node) | Python Bridge |
+|------|-------------------|---------------|
+| **性能** | ~0ms(进程内调用) | ~50-100ms(子进程启动) |
+| **可读性** | 编译后不可读 | 660 行清晰的 Python |
+| **可修改性** | 需要 Swift 编译环境 | 直接编辑 .py 文件 |
+| **依赖** | 特定 Bun 版本的 NAPI | 任意 Python 3.8+ |
+| **跨平台** | 仅 macOS | pyautogui/mss 天然跨平台 |
+| **用户体验** | 无感知 | 无感知(模型思考时间秒级) |
+
+**结论**:50-100ms 的额外延迟在 Computer Use 的场景下完全可以忽略——模型分析截图和决策的时间通常是 2-5 秒,用户不会注意到底层操作多了 100ms。
+
+### 我们尝试过但放弃的方案
+
+**方案一:提取原生 .node 模块**
+- 从 Claude Code 二进制中成功提取了 `computer-use-swift.node`(ARM64 424KB)
+- 同步方法正常工作,但 **Swift 异步方法的 continuation 永远不会 resume**
+- 根因:.node 文件针对 Claude Code 内置 Bun 编译,与用户 Bun 版本不兼容
+
+**方案二:空 Stub 包**
+- 代码能编译但所有操作报错——没有实际执行能力
+
+---
