This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
This is a reverse-engineered / decompiled version of Anthropic's official Claude Code CLI tool. The goal is to restore core functionality while trimming secondary capabilities. Many modules are stubbed or feature-flagged off. The codebase has ~1341 tsc errors from decompilation (mostly unknown/never/{} types) — these do not block Bun runtime execution.

- Runtime: Bun (not Node.js). All imports, builds, and execution use Bun APIs.
- Build:
build.ts执行Bun.build()withsplitting: 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-dflag 注入MACRO.*defines,运行src/entrypoints/cli.tsx。默认启用全部 feature。 - Module system: ESM (
"type": "module"), TSX withreact-jsxtransform. - Monorepo: Bun workspaces — 14 个 internal packages in
packages/resolved viaworkspace:*。 - 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)。

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.
src/services/api/claude.ts— Core API client. Builds request params (system prompt, messages, tools, betas), calls the Anthropic SDK streaming endpoint, and processesBetaRawMessageStreamEventevents.- 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。
src/Tool.ts— Tool interface definition (Tooltype) and utilities (findToolByName,toolMatchesName).src/tools.ts(387 行) — Tool registry.

src/tools/shared/— Tool 共享工具函数。
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 renderingPromptInput/— User input handlingpermissions/— Tool permission approval UIdesign-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.
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).

src/bridge/(~37 files) — Remote Control / Bridge 模式。feature-gated byBRIDGE_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:
claude remote-control/claude rc/claude bridge。 - 详见
docs/features/remote-control-self-hosting.md。
src/daemon/— Daemon 模式(长驻 supervisor)。feature-gated byDAEMON。包含main.ts(entry)和workerRegistry.ts(worker 管理)。
src/context.ts— Builds system/user context for the API call (git status, date, CLAUDE.md contents, memory files).src/utils/claudemd.ts— Discovers and loads CLAUDE.md files from project hierarchy.
Feature flags control which functionality is enabled at runtime. 代码中统一通过 import { feature } from 'bun:bundle' 导入,调用 feature('FLAG_NAME') 返回 boolean。
启用方式: 环境变量 FEATURE_<FLAG_NAME>=1。例如 FEATURE_BUDDY=1 bun run dev。
Build 默认 features(19 个,见 build.ts):
- 基础:
BUDDY,TRANSCRIPT_CLASSIFIER,BRIDGE_MODE,AGENT_TRIGGERS_REMOTE,CHICAGO_MCP,VOICE_MODE - 统计/缓存:
SHOT_STATS,PROMPT_CACHE_BREAK_DETECTION,TOKEN_BUDGET - P0 本地:
AGENT_TRIGGERS,ULTRATHINK,BUILTIN_EXPLORE_PLAN_AGENTS,LODESTONE - P1 API 依赖:
EXTRACT_MEMORIES,VERIFICATION_AGENT,KAIROS_BRIEF,AWAY_SUMMARY,ULTRAPLAN - P2:
DAEMON
Dev mode 默认: 全部启用(见 scripts/dev.ts)。
类型声明: src/types/internal-modules.d.ts 中声明了 bun:bundle 模块的 feature 函数签名。
新增功能的正确做法: 保留 import { feature } from 'bun:bundle' + feature('FLAG_NAME') 的标准模式,在运行时通过环境变量或配置控制,不要绕过 feature flag 直接 import。
所有兼容层均采用流适配器模式:将第三方 API 格式转为 Anthropic 内部格式,下游代码完全不改。
通过 CLAUDE_CODE_USE_OPENAI=1 启用,支持 Ollama/DeepSeek/vLLM 等任意 OpenAI Chat Completions 协议端点。含 DeepSeek thinking mode 支持。
src/services/api/openai/— client、消息/工具转换、流适配、模型映射- 关键环境变量:
CLAUDE_CODE_USE_OPENAI、OPENAI_API_KEY、OPENAI_BASE_URL、OPENAI_MODEL
通过 CLAUDE_CODE_USE_GEMINI=1 启用。独立环境变量体系。
src/services/api/gemini/— client、模型映射、类型定义- 关键环境变量:
GEMINI_API_KEY(必填)、GEMINI_MODEL(直接指定)、GEMINI_DEFAULT_SONNET_MODEL/GEMINI_DEFAULT_OPUS_MODEL(按能力映射) - 模型映射优先级:
GEMINI_MODEL>GEMINI_DEFAULT_*_MODEL>ANTHROPIC_DEFAULT_*_MODEL(已废弃) > 原样返回
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

src/types/global.d.ts— DeclaresMACRO,BUILD_TARGET,BUILD_ENVand internal Anthropic-only identifiers.src/types/internal-modules.d.ts— Type declarations forbun: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.
- 框架:
bun:test(内置断言 + mock) - 当前状态: 2453 tests / 137 files / 0 fail / 4015 expect() calls
- 单元测试: 就近放置于
src/**/__tests__/,文件名<module>.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-napi11 tests)
- Don't try to fix all tsc errors — they're from decompilation and don't affect runtime.
- 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:bundleimport —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。src/path alias — tsconfig mapssrc/*to./src/*. Imports likeimport { ... } from 'src/utils/...'are valid.- MACRO defines — 集中管理在
scripts/defines.ts。Dev mode 通过bun -d注入,build 通过Bun.build({ define })注入。修改版本号等常量只改这个文件。 - 构建产物兼容 Node.js —
build.ts会自动后处理import.meta.require,产物可直接用node dist/cli.js运行。 - Biome 配置 — 大量 lint 规则被关闭(decompiled 代码不适合严格 lint)。
.tsx文件用 120 行宽 + 强制分号;其他文件 80 行宽 + 按需分号。 - Ink 框架在
packages/@ant/ink/— 不是src/ink/(该目录不存在)。Ink 相关的组件、hooks、keybindings 都在 packages 中。 - Provider 优先级 —
modelType参数 > 环境变量 > 默认firstParty。新增 provider 需在src/utils/model/providers.ts注册。
本代码库经过系统性类型修复,已消除非测试代码中的所有 as any。后续开发应遵守以下规则:
- 禁止在非测试代码中使用
as any— 测试文件中as any用于 mock 数据是可以接受的。生产代码中如果遇到类型不匹配,优先用以下方式解决:- 补充缺失的类型声明或 interface
- 使用
as unknown as SpecificType双重断言(比as any安全,至少表达了目标类型) - 使用
Record<string, unknown>替代any访问未知结构的对象 - 用类型守卫(type guard)收窄联合类型
msg.request模式 — SDK control request 的某些子类型不在 Zod schema 中,访问其属性时使用const req = msg.request as Record<string, unknown>然后通过req.propertyName as string访问。- Ink 颜色类型 — Text 组件的
colorprop 是有限联合类型,需要强转时用as keyof Theme而非as any。 - API 兼容层类型 — OpenAI/Gemini/Grok 兼容层的 stream、request body、error 等使用对应的 SDK 类型(如
ChatCompletionChunk、ChatCompletionCreateParamsStreaming),已在各index.ts中导入。 - Transport 消息类型 — Bridge 的
transport.write()/transport.writeBatch()使用StdoutMessage类型,已在src/bridge/中导入。
