# Claude Code (Reverse-Engineered)
2+
3+
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。
4+
5+
## 核心能力
6+
7+
- API 通信（Anthropic SDK / Bedrock / Vertex）
8+
- Bash / FileRead / FileWrite / FileEdit 等核心工具
9+
- REPL 交互界面（ink 终端渲染）
10+
- 对话历史与会话管理
11+
- 权限系统
12+
- Agent / 子代理系统
13+
14+
## 已删减模块
15+
16+
| 模块 | 处理方式 |
17+
|------|----------|
18+
| Computer Use (`@ant/computer-use-*`) | stub |
19+
| Claude for Chrome MCP | stub |
20+
| Magic Docs / Voice Mode / LSP Server | 移除 |
21+
| Analytics / GrowthBook / Sentry | 空实现 |
22+
| Plugins / Marketplace / Desktop Upsell | 移除 |
23+
| Ultraplan / Tungsten / Auto Dream | 移除 |
24+
| MCP OAuth/IDP | 简化 |
25+
| DAEMON / BRIDGE / BG_SESSIONS / TEMPLATES 等 | feature flag 关闭 |
26+
27+
## 快速开始
28+
29+
### 环境要求
30+
31+
- [Bun](https://bun.sh/) >= 1.0
32+
- Node.js >= 18（部分依赖需要）
33+
- 有效的 Anthropic API Key（或 Bedrock / Vertex 凭据）
34+
35+
### 安装
36+
37+
```bash
38+
bun install
39+
```
40+
41+
### 运行
42+
43+
```bash
44+
# 开发模式（watch）
45+
bun run dev
46+
47+
# 直接运行
48+
bun run src/entrypoints/cli.tsx
49+
50+
# 管道模式（-p）
51+
echo "say hello" | bun run src/entrypoints/cli.tsx -p
52+
53+
# 构建
54+
bun run build
55+
```
56+
57+
构建产物输出到 `dist/cli.js`（~25 MB，5300+ 模块）。
58+
59+

```
86+
87+
## 技术说明
88+
89+
### 运行时 Polyfill
90+
91+
入口文件 `src/entrypoints/cli.tsx` 顶部注入了必要的 polyfill：
92+
93+
- `feature()` — 所有 feature flag 返回 `false`，跳过未实现分支
94+
- `globalThis.MACRO` — 模拟构建时宏注入（VERSION 等）
95+
96+
### 类型状态
97+
98+
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**。
99+
100+
### Monorepo
101+
102+
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。
103+
104+
## 许可证
105+
106+
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）
110+
111+
### 5.1 背景
112+
113+
`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：
114+
```
115+
ERROR Object is not a constructor (evaluating 'new ColorDiff(patch, firstLine, filePath, fileContent)')
116+
```
117+
同时 `@ant/*`、其他 `*-napi` 包也只有 `declare module` 类型声明，无运行时实现。
118+
119+
### 5.2 方案
120+
121+
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。
122+
123+
### 5.3 创建的 workspace 包
124+
125+
| 包名 | 路径 | 类型 |
126+
|------|------|------|
127+
| `color-diff-napi` | `packages/color-diff-napi/` | 完整实现（~1000行 TS，从 `src/native-ts/color-diff/` 移入） |
128+
| `modifiers-napi` | `packages/modifiers-napi/` | stub（macOS 修饰键检测） |
129+
| `audio-capture-napi` | `packages/audio-capture-napi/` | stub |
130+
| `image-processor-napi` | `packages/image-processor-napi/` | stub |
131+
| `url-handler-napi` | `packages/url-handler-napi/` | stub |
132+
| `@ant/claude-for-chrome-mcp` | `packages/@ant/claude-for-chrome-mcp/` | stub |
133+
| `@ant/computer-use-mcp` | `packages/@ant/computer-use-mcp/` | stub（含 subpath exports: sentinelApps, types） |
134+
| `@ant/computer-use-input` | `packages/@ant/computer-use-input/` | stub |
135+
| `@ant/computer-use-swift` | `packages/@ant/computer-use-swift/` | stub |
136+
137+
### 5.4 新增的 npm 依赖
138+
139+
| 包名 | 原因 |
140+
|------|------|
141+
| `@opentelemetry/semantic-conventions` | 构建报错缺失 |
142+
| `fflate` | `src/utils/dxt/zip.ts` 动态 import |
143+
| `vscode-jsonrpc` | `src/services/lsp/LSPClient.ts` import |
144+
| `@aws-sdk/credential-provider-node` | `src/utils/proxy.ts` 动态 import |
145+
146+
### 5.5 关键变更
147+
148+
- `package.json`：添加 `workspaces`，添加所有 workspace 包和缺失 npm 依赖
149+
- `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`
150+
- `src/native-ts/color-diff/` → `packages/color-diff-napi/src/`：移动并内联了对 `stringWidth` 和 `logError` 的依赖
151+
- 删除 `node_modules/color-diff-napi/` 手工 stub
152+
153+
### 5.6 构建验证
154+
155+
```
156+
$ bun run build
157+
Bundled 5326 modules in 491ms
158+
cli.js 25.74 MB (entry point)
159+
```
