All imports, builds, and execution use Bun APIs. +- **Build**: `build.ts` 执行 `Bun.build()` with `splitting: true`，入口 `src/entrypoints/cli.tsx`，输出 `dist/cli.js` + chunk files。Build 默认启用 19 个 feature（见下方 Feature Flag 段）。构建后自动替换 `import.meta.require` 为 Node.js 兼容版本（产物 bun/node 都可运行）。 +- **Dev mode**: `scripts/dev.ts` 通过 Bun `-d` flag 注入 `MACRO.*` defines，运行 `src/entrypoints/cli.tsx`。默认启用全部 feature。 +- **Module system**: ESM (`"type": "module"`), TSX with `react-jsx` transform. +- **Monorepo**: Bun workspaces — 14 个 internal packages in `packages/` resolved via `workspace:*`。 +- **Lint/Format**: Biome (`biome.json`)。`bun run lint` / `bun run lint:fix` / `bun run format`。 +- **Defines**: 集中管理在 `scripts/defines.ts`。当前版本 `2.1.888`。 +- **CI**: GitHub Actions — `ci.yml`（构建+测试）、`release-rcs.yml`（RCS 发布）、`update-contributors.yml`（自动更新贡献者）。 + +### Entry & Bootstrap + +1. **`src/entrypoints/cli.tsx`** (323 行) — True entrypoint。`main()` 函数按优先级处理多条快速路径： + - `--version` / `-v` — 零模块加载 + - `--dump-system-prompt` — feature-gated (DUMP_SYSTEM_PROMPT) + - `--Codex-in-chrome-mcp` / `--chrome-native-host` + - `--computer-use-mcp` — 独立 MCP server 模式 + - `--daemon-worker=` — feature-gated (DAEMON) + - `remote-control` / `rc` / `remote` / `sync` / `bridge` — feature-gated (BRIDGE_MODE) + - `daemon` [subcommand] — feature-gated (DAEMON) + - `ps` / `logs` / `attach` / `kill` / `--bg` — feature-gated (BG_SESSIONS) + - `new` / `list` / `reply` — Template job commands + - `environment-runner` / `self-hosted-runner` — BYOC runner + - `--tmux` + `--worktree` 组合 + - 默认路径：加载 `main.tsx` 启动完整 CLI +2. **`src/main.tsx`** (~6970 行) — Commander.js CLI definition。注册大量 subcommands：`mcp` (serve/add/remove/list...)、`server`、`ssh`、`open`、`auth`、`plugin`、`agents`、`auto-mode`、`doctor`、`update` 等。主 `.action()` 处理器负责权限、MCP、会话恢复、REPL/Headless 模式分发。 +3. **`src/entrypoints/init.ts`** — One-time initialization (telemetry, config, trust dialog)。 + +### Core Loop + +- **`src/query.ts`** — The main API query function. Sends messages to Codex API, handles streaming responses, processes tool calls, and manages the conversation turn loop. +- **`src/QueryEngine.ts`** — Higher-level orchestrator wrapping `query()`. Manages conversation state, compaction, file history snapshots, attribution, and turn-level bookkeeping. Used by the REPL screen. +- **`src/screens/REPL.tsx`** — The interactive REPL screen (React/Ink component). Handles user input, message display, tool permission prompts, and keyboard shortcuts. + +### API Layer + +- **`src/services/api/Codex.ts`** — Core API client. Builds request params (system prompt, messages, tools, betas), calls the Anthropic SDK streaming endpoint, and processes `BetaRawMessageStreamEvent` events. +- **7 providers**: `firstParty` (Anthropic direct), `bedrock` (AWS), `vertex` (Google Cloud), `foundry`, `openai`, `gemini`, `grok` (xAI)。 +- Provider selection in `src/utils/model/providers.ts`。优先级：modelType 参数 > 环境变量 > 默认 firstParty。 + +### Tool System + +- **`src/Tool.ts`** — Tool interface definition (`Tool` type) and utilities (`findToolByName`, `toolMatchesName`). +- **`src/tools.ts`** (387 行) — Tool registry. Assembles the tool list; some tools are conditionally loaded via `feature()` flags or `process.env.USER_TYPE`. +- **`src/tools//`** — 55 个 tool 目录。主要分类： + - **文件操作**: FileEditTool, FileReadTool, FileWriteTool, GlobTool, GrepTool + - **Shell/执行**: BashTool, PowerShellTool, REPLTool + - **Agent 系统**: AgentTool, TaskCreateTool, TaskUpdateTool, TaskListTool, TaskGetTool + - **规划**: EnterPlanModeTool, ExitPlanModeV2Tool, VerifyPlanExecutionTool + - **Web/MCP**: WebFetchTool, WebSearchTool, MCPTool, McpAuthTool + - **调度**: CronCreateTool, CronDeleteTool, CronListTool + - **其他**: LSPTool, ConfigTool, SkillTool, EnterWorktreeTool, ExitWorktreeTool 等 +- **`src/tools/shared/`** — Tool 共享工具函数。 + +### UI Layer (Ink) + +- **`src/ink.ts`** — Ink render wrapper with ThemeProvider injection. +- **`packages/@ant/ink/`** — Custom Ink framework（forked/internal），包含 components、core、hooks、keybindings、theme、utils。注意：不是 `src/ink/`。 +- **`src/components/`** — 149 个组件目录/文件，渲染于终端 Ink 环境中。关键组件： + - `App.tsx` — Root provider (AppState, Stats, FpsMetrics) + - `Messages.tsx` / `MessageRow.tsx` — Conversation message rendering + - `PromptInput/` — User input handling + - `permissions/` — Tool permission approval UI + - `design-system/` — 复用 UI 组件（Dialog, FuzzyPicker, ProgressBar, ThemeProvider 等） +- Components use React Compiler runtime (`react/compiler-runtime`) — decompiled output has `_c()` memoization calls throughout. + +### State Management + +- **`src/state/AppState.tsx`** — Central app state type and context provider. Contains messages, tools, permissions, MCP connections, etc. +- **`src/state/AppStateStore.ts`** — Default state and store factory. +- **`src/state/store.ts`** — Zustand-style store for AppState (`createStore`). +- **`src/state/selectors.ts`** — State selectors. +- **`src/bootstrap/state.ts`** — Module-level singletons for session-global state (session ID, CWD, project root, token counts, model overrides, client type, permission mode). + +### Workspace Packages + +| Package | 说明 | +|---------|------| +| `packages/@ant/ink/` | Forked Ink 框架（components、hooks、keybindings、theme） | +|

Control + +- **`src/bridge/`** (~37 files) — Remote Control / Bridge 模式。feature-gated by `BRIDGE_MODE`。包含 bridge API、会话管理、JWT 认证、消息传输、权限回调等。Entry: `bridgeMain.ts`。 +- **`packages/remote-control-server/`** — 自托管 RCS，支持 Docker 部署，含 Web UI 控制面板。通过 `bun run rcs` 启动。 +- CLI 快速路径: `Codex remote-control` / `Codex rc` / `Codex bridge`。 +- 详见

`ANTHROPIC_DEFAULT_*_MODEL`(已废弃) > 原样返回 + +#### Grok 兼容层 + +通过 `CLAUDE_CODE_USE_GROK=1` 启用。自定义模型映射支持 xAI Grok API。 + +- **`src/services/api/grok/`** — client、模型映射 + +详见各兼容层的 docs 文档。 + +### Stubbed/Deleted Modules + +| Module | Status | +|--------|--------| +| Computer Use (`@ant/*`) | Restored — macOS + Windows + Linux（后端完整度不一） | +| `*-napi` packages | `audio-capture-napi`、`image-processor-napi` 已恢复；`color-diff-napi` 完整；`modifiers-napi`、`url-handler-napi` 仍为 stub | +| Voice Mode | Restored — Push-to-Talk 语音输入（需 Anthropic OAuth） | +| OpenAI/Gemini/Grok 兼容层 | Restored | +| Remote Control Server | Restored — 自托管 RCS + Web UI | +| Analytics / GrowthBook / Sentry | Empty implementations | +| Magic Docs / LSP Server | Removed | +| Plugins / Marketplace | Removed | +| MCP OAuth | Simplified | + +### Key Type Files + +- **`src/types/global.d.ts`** — Declares `MACRO`, `BUILD_TARGET`, `BUILD_ENV` and internal Anthropic-only identifiers. +- **`src/types/internal-modules.d.ts`** — Type declarations for `bun:bundle`, `bun:ffi`, `@anthropic-ai/mcpb`. +- **`src/types/message.ts`** — Message type hierarchy (UserMessage, AssistantMessage, SystemMessage, etc.). +- **`src/types/permissions.ts`** — Permission mode and result types. + +## Testing + +- **框架**: `bun:test`（内置断言 + mock） +- **当前状态**: 2472 tests / 138 files / 0 fail +- **单元测试**: 就近放置于 `src/**/__tests__/`，文件名 `.test.ts` +- **集成测试**: `tests/integration/` — 4 个文件（cli-arguments, context-build, message-pipeline, tool-chain） +- **共享 mock/fixture**: `tests/mocks/`（api-responses, file-system, fixtures/） +- **命名**: `describe("functionName")` + `test("behavior description")`，英文 +- **Mock 模式**: 对重依赖模块使用 `mock.module()` + `await import()` 解锁（必须内联在测试文件中，不能从共享 helper 导入） +- **包测试**: `packages/` 下各包也有独立测试（如 `color-diff-napi` 11 tests） + +### 类型检查 + +项目使用 TypeScript strict 模式，**tsc 必须零错误**。每次修改后运行： + +```bash +bunx tsc --noEmit +``` + +**类型规范**： +- 生产代码禁止 `as any`；测试文件中 mock 数据可用 `as any` +- 类型不匹配优先用 `as unknown as SpecificType` 双重断言，或补充 interface +- 未知结构对象用 `Record` 替代 `any` +- 联合类型用类型守卫（type guard）收窄，不要强转 +- `msg.request` 属性访问：`const req = msg.request as Record` +- Ink `color` prop：用 `as keyof Theme` 而非 `as any` + +## Working with This Codebase + +- **tsc must pass** — `bunx tsc --noEmit` 必须零错误，任何修改都不能引入新的类型错误。 +- **Feature flags** — 默认全部关闭（`feature()` 返回 `false`）。Dev/build 各有自己的默认启用列表。不要在 `cli.tsx` 中重定义 `feature` 函数。 +- **React Compiler output** — Components have decompiled memoization boilerplate (`const $ = _c(N)`). This is normal. +- **`bun:bundle` import** — `import { feature } from 'bun:bundle'` 是 Bun 内置模块，由运行时/构建器解析。不要用自定义函数替代它。**`feature()` 只能直接用在 `if` 语句或三元表达式的条件位置**（Bun 编译器限制），不能赋值给变量、不能放在箭头函数体里、不能作为 `&&` 链的一部分。正确：`if (feature('X')) {}` 或 `feature('X') ? a : b`。 +- **`src/` path alias** — tsconfig maps `src/*` to `./src/*`.
