+# Claude Code (Reverse-Engineered)
+
+Anthropic 官方 [Claude Code](https://docs.anthropic.com/en/docs/claude-code) CLI 工具的源码反编译/逆向还原项目。目标是将 Claude Code 核心功能跑通，必要时删减次级能力。
+
+## 核心能力
+
+- API 通信（Anthropic SDK / Bedrock / Vertex）
+- Bash / FileRead / FileWrite / FileEdit 等核心工具
+- REPL 交互界面（ink 终端渲染）
+- 对话历史与会话管理
+- 权限系统
+- Agent / 子代理系统
+
+## 已删减模块
+
+| 模块 | 处理方式 |
+|------|----------|
+| Computer Use (`@ant/computer-use-*`) | stub |
+| Claude for Chrome MCP | stub |
+| Magic Docs / Voice Mode / LSP Server | 移除 |
+| Analytics / GrowthBook / Sentry | 空实现 |
+| Plugins / Marketplace / Desktop Upsell | 移除 |
+| Ultraplan / Tungsten / Auto Dream | 移除 |
+| MCP OAuth/IDP | 简化 |
+| DAEMON / BRIDGE / BG_SESSIONS / TEMPLATES 等 | feature flag 关闭 |
+
+## 快速开始
+
+### 环境要求
+
+- [Bun](https://bun.sh/) >= 1.0
+- Node.js >= 18（部分依赖需要）
+- 有效的 Anthropic API Key（或 Bedrock / Vertex 凭据）
+
+### 安装
+
+```bash
+bun install
+```
+
+### 运行
+
+```bash
+# 开发模式（watch）
+bun run dev
+
+# 直接运行
+bun run src/entrypoints/cli.tsx
+
+# 管道模式（-p）
+echo "say hello" | bun run src/entrypoints/cli.tsx -p
+
+# 构建
+bun run build
+```
+
+构建产物输出到 `dist/cli.js`（~25 MB，5300+ 模块）。

+```
+
+## 技术说明
+
+### 运行时 Polyfill
+
+入口文件 `src/entrypoints/cli.tsx` 顶部注入了必要的 polyfill：
+
+- `feature()` — 所有 feature flag 返回 `false`，跳过未实现分支
+- `globalThis.MACRO` — 模拟构建时宏注入（VERSION 等）
+
+### 类型状态
+
+仍有 ~1341 个 tsc 错误，均为反编译产生的源码级类型问题（`unknown` / `never` / `{}`），**不影响 Bun 运行时**。
+
+### Monorepo
+
+项目采用 Bun workspaces 管理内部包。原先手工放在 `node_modules/` 下的 stub 已统一迁入 `packages/`，通过 `workspace:*` 解析。
+
+## 许可证
+
+本项目仅供学习研究用途。Claude Code 的所有权利归 [Anthropic](https://www.anthropic.com/) 所有。

+## 五、Monorepo 改造（2026-03-31）
+
+### 5.1 背景
+
+`color-diff-napi` 原先是手工放在 `node_modules/` 下的 stub 文件，导出的是普通对象而非 class，导致 `new ColorDiff(...)` 报错：
+```
+ERROR Object is not a constructor (evaluating 'new ColorDiff(patch, firstLine, filePath, fileContent)')
+```
+同时 `@ant/*`、其他 `*-napi` 包也只有 `declare module` 类型声明，无运行时实现。
+
+### 5.2 方案
+
+将项目改造为 **Bun workspaces monorepo**，所有内部包统一放在 `packages/` 下，通过 `workspace:*` 依赖解析。
+
+### 5.3 创建的 workspace 包
+
+| 包名 | 路径 | 类型 |
+|------|------|------|
+| `color-diff-napi` | `packages/color-diff-napi/` | 完整实现（~1000行 TS，从 `src/native-ts/color-diff/` 移入） |
+| `modifiers-napi` | `packages/modifiers-napi/` | stub（macOS 修饰键检测） |
+| `audio-capture-napi` | `packages/audio-capture-napi/` | stub |
+| `image-processor-napi` | `packages/image-processor-napi/` | stub |
+| `url-handler-napi` | `packages/url-handler-napi/` | stub |
+| `@ant/claude-for-chrome-mcp` | `packages/@ant/claude-for-chrome-mcp/` | stub |
+| `@ant/computer-use-mcp` | `packages/@ant/computer-use-mcp/` | stub（含 subpath exports: sentinelApps, types） |
+| `@ant/computer-use-input` | `packages/@ant/computer-use-input/` | stub |
+| `@ant/computer-use-swift` | `packages/@ant/computer-use-swift/` | stub |
+
+### 5.4 新增的 npm 依赖
+
+| 包名 | 原因 |
+|------|------|
+| `@opentelemetry/semantic-conventions` | 构建报错缺失 |
+| `fflate` | `src/utils/dxt/zip.ts` 动态 import |
+| `vscode-jsonrpc` | `src/services/lsp/LSPClient.ts` import |
+| `@aws-sdk/credential-provider-node` | `src/utils/proxy.ts` 动态 import |
+
+### 5.5 关键变更
+
+- `package.json`：添加 `workspaces`，添加所有 workspace 包和缺失 npm 依赖
+- `src/types/internal-modules.d.ts`：删除已移入 monorepo 的 `declare module` 块，仅保留 `bun:bundle`、`bun:ffi`、`@anthropic-ai/mcpb`
+- `src/native-ts/color-diff/` → `packages/color-diff-napi/src/`：移动并内联了对 `stringWidth` 和 `logError` 的依赖
+- 删除 `node_modules/color-diff-napi/` 手工 stub
+
