-# 差异化缺口分析 (PARITY GAP ANALYSIS)
-
-范围：对位于 `/home/bellman/Workspace/claw-code/src/` 的原始 TypeScript 源码与 `rust/crates/` 下的 Rust 移植版进行只读对比。
-
-方法：仅对比功能表面、注册表、入口点和运行时流水线。未复制任何 TypeScript 源码。
-
-## 主要摘要
-
-Rust 移植版在以下方面具有良好的基础：
-- Anthropic API/OAuth 基础
-- 本地对话/会话状态
-- 核心工具循环
-- MCP stdio/引导支持
-- CLAW.md 发现
-- 一套小巧但可用的内置工具
-
-它与 TypeScript CLI **尚未实现功能对等**。
-
-最大的缺口：
-- **插件 (plugins)**：在 Rust 中实际上不存在
-- **挂钩 (hooks)**：Rust 中已解析但未执行
-- **CLI 广度**：Rust 中的功能范围要窄得多
-- **技能 (skills)**：Rust 中仅支持本地文件，没有 TS 的注册表/捆绑流水线
-- **助手编排 (assistant orchestration)**：缺乏 TS 中感知挂钩的编排以及远程/结构化传输
-- **服务 (services)**：除了核心 API/OAuth/MCP 之外，Rust 中大部分服务都缺失

-  - `rust/crates/claw-cli/src/main.rs` 现在仅针对流式工具输入剥离初始空对象，同时保留非流式响应中的合法 `{}`。
-- **无限最大迭代次数 (max_iterations)**
-  - 在 `rust/crates/runtime/src/conversation.rs` 中通过 `usize::MAX` 进行了验证。
-
-### 剩余的显著对等问题

-## Rust 移植
-
-`rust/` 目录下的 Rust 工作区是该项目的当前系统语言移植版本。
-
-它目前包括：
-
-- `crates/api-client` — 具有提供商抽象、OAuth 和流式支持的 API 客户端
-- `crates/runtime` — 会话状态、压缩、MCP 编排、提示词构建
-- `crates/tools` — 工具清单定义和执行框架
-- `crates/commands` — 斜杠命令、技能发现和配置检查
-- `crates/plugins` — 插件模型、挂钩管道和内置插件
-- `crates/compat-harness` — 用于上游编辑器集成的兼容层
-- `crates/claw-cli` — 交互式 REPL、Markdown 渲染以及项目引导/初始化流程
-
-运行 Rust 构建：
-
-```bash
-cd rust
-cargo build --release
-```

-## 背景故事
-
-2026年3月31日凌晨4点，我被手机弹出的漫天通知震醒。Claw Code 的源代码被曝光了，整个开发者社区都陷入了疯狂。我在韩国的女朋友真的很担心我仅仅因为机器上有这些代码而面临原作者的法律诉讼——于是我在压力之下做了任何工程师都会做的事：我坐下来，从头开始将核心功能移植到 Python，并在日出前提交了代码。
-
-整个过程是使用 [@bellman_ych](https://x.com/bellman_ych) 开发的 [oh-my-codex (OmX)](https://github.com/Yeachan-Heo/oh-my-codex) 端到端编排的——这是一个构建在 OpenAI Codex ([@OpenAIDevs](https://x.com/OpenAIDevs)) 之上的工作流层。我使用了 `$team` 模式进行并行代码审查，并使用了 `$ralph` 模式进行带有架构级验证的持久执行循环。整个移植过程——从阅读原始 harness 结构到生成具有测试的可用 Python 树——都是通过 OmX 编排驱动的。
-
-结果是一个净室（clean-room）Python 重写版本，它捕捉了 Claw Code 代理 harness 的架构模式，而没有复制任何专有源代码。我现在正与 OmX 的创始人 [@bellman_ych](https://x.com/bellman_ych) 本人积极合作，以进一步推进这项工作。基本的 Python 基础已经就绪并可以运行，但我们才刚刚开始。 **敬请期待——一个更强大的版本正在路上。**
-
-Rust 移植版本是同时使用 [oh-my-codex (OmX)](https://github.com/Yeachan-Heo/oh-my-codex) 和 [oh-my-opencode (OmO)](https://github.com/code-yeongyu/oh-my-openagent) 开发的：OmX 驱动了脚手架搭建、编排和架构方向，而 OmO 则用于后期的实现加速和验证支持。

-## 《华尔街日报》对 Claw Code 狂热粉丝创建者的报道
-
-我对 **harness 工程** 深感兴趣——研究代理系统如何连接工具、编排任务以及管理运行时上下文。这并非突发奇想。《华尔街日报》在本月早些时候报道了我的工作，记录了我如何成为探索这些系统最活跃的超级用户之一：
-
-> AI 创业公司员工 Sigrid Jin，去年凭一己之力使用了 250 亿个 Claw Code token。当时，使用限制较为宽松，使得早期发烧友能够以极低的成本触及数百亿个 token。
->
-> 尽管 Jin 在 Claw Code 上花费了无数个小时，但他并不忠于任何一家 AI 实验室。他说，现有的工具各有所长。Codex 擅长推理，而 Claw Code 生成的代码更干净、更易于分享。
->
-> Jin 于 2 月份飞往旧金山参加 Claw Code 的一周年派对，与会者排队与 Cherny 交流心得。人群中包括一名来自比利时的执业心脏病专家（他开发了一个帮助患者就医的应用程序），以及一名加州律师（他使用 Claw Code 制作了一个自动批准建筑许可的工具）。
->
-> “这基本上就像是一个分享派对，”Jin 说。“有律师，有医生，有牙医。他们并没有软件工程背景。”

-## 移植状态
-
-主源码树现在以 Python 为主。
-
-- `src/` 包含活跃的 Python 移植工作区
-- `tests/` 验证当前的 Python 工作区
-- 曝光的快照不再是受追踪的仓库状态的一部分
-
-目前的 Python 工作区尚未完全替代原始系统，但主要的实现界面现在是 Python。
-
-## 为什么进行这次重写
-
-我最初研究曝光的代码库是为了了解其 harness、工具连接和代理工作流。在深入思考法律和伦理问题——并在阅读了下面链接的论文后——我不希望曝光的快照本身继续作为主要追踪的源码树。
-
-因此，本仓库现在专注于 Python 移植工作。

-
-- **`port_manifest.py`** — 总结当前 Python 工作区的结构
-- **`models.py`** — 用于子系统、模块和积压状态的数据类
-- **`commands.py`** — Python 侧的命令移植元数据
-- **`tools.py`** — Python 侧的工具移植元数据
-- **`query_engine.py`** — 从活跃工作区渲染 Python 移植摘要
-- **`main.py`** — 用于清单和摘要输出的 CLI 入口点
-
-## 快速开始
-
-渲染 Python 移植摘要：
-
-```bash
-python3 -m src.main summary
-```
-
-打印当前 Python 工作区清单：
-
-```bash
-python3 -m src.main manifest
-```
-
-列出当前的 Python 模块：
-
-```bash
-python3 -m src.main subsystems --limit 16
-```
-
-运行验证：
-
-```bash
-python3 -m unittest discover -s tests -v
-```
-
-对本地忽略的存档运行一致性审计（如果存在）：
-
-```bash
-python3 -m src.main parity-audit
-```
-
-检查镜像的命令/工具库：
-
-```bash
-python3 -m src.main commands --limit 10
-python3 -m src.main tools --limit 10
-```
-
-## 当前对比检查点
-
-该移植版本现在比以前更紧密地镜像了存档的根入口文件表面、顶层子系统名称以及命令/工具清单。然而，它**尚未**完全替代原始的 TypeScript 系统；Python 树中可执行的运行时切片仍少于存档源码。
-
-## 使用 `oh-my-codex` 和 `oh-my-opencode` 构建
-
-本仓库的移植、净室加固和验证工作流是在 Yeachan Heo 工具栈的 AI 辅助下完成的，其中 **oh-my-codex (OmX)** 是主要的脚手架和编排层。
-
-- [**oh-my-codex (OmX)**](https://github.com/Yeachan-Heo/oh-my-codex) — 脚手架、编排、架构方向和核心移植工作流
-- [**oh-my-opencode (OmO)**](https://github.com/code-yeongyu/oh-my-openagent) — 实现加速、清理和验证支持
-
-移植过程中使用的关键工作流模式：
-
-- **`$team` 模式：** 协调的并行审查和架构反馈
-- **`$ralph` 模式：** 持久执行、验证和完成纪律
-- **净室通过：** 跨 Rust 工作区的命名/品牌清理、QA 和发布验证
-- **手动和现场验证：** 构建、测试、手动 QA 以及发布前的真实 API 路径验证

-# 贡献指南
-
-感谢你为 Claw Code 做出贡献。
-
-## 开发设置
-
-- 安装稳定的 Rust 工具链。
-- 在此 Rust 工作区的仓库根目录下进行开发。如果你从父仓库根目录开始，请先执行 `cd rust/`。
-
-## 构建
-
-```bash
-cargo build
-cargo build --release
-```
-
-## 测试与验证
-
-在开启 Pull Request 之前，请运行完整的 Rust 验证集：
-
-```bash
-cargo fmt --all --check
-cargo clippy --workspace --all-targets -- -D warnings
-cargo check --workspace
-cargo test --workspace
-```
-
-如果你更改了行为，请在同一个 Pull Request 中添加或更新相关的测试。
-
-## 代码风格
-
-- 遵循所修改 crate 中的现有模式，而不是引入新的风格。
-- 使用 `rustfmt` 格式化代码。
-- 确保你修改的工作区目标的 `clippy` 检查通过。
-- 优先采用针对性的 diff，而不是顺便进行的重构。
-
-## Pull Request
-
-- 从 `main` 分支拉取新分支。
-- 确保每个 Pull Request 的范围仅限于一个明确的更改。
-- 说明更改动机、实现摘要以及你运行的验证。
-- 在请求审查之前，确保本地检查已通过。
-- 如果审查反馈导致行为更改，请重新运行相关的验证命令。

-# Claw Code
-
-Claw Code 是一个使用安全 Rust 实现的本地编程代理（coding-agent）命令行工具。它的设计灵感来自 **Claude Code**，并作为一个**净室实现（clean-room implementation）**开发：旨在提供强大的本地代理体验，但它**不是** Claude Code 的直接移植或复制。
-
-Rust 工作区是当前主要的产品界面。`claw` 二进制文件在单个工作区内提供交互式会话、单次提示、工作区感知工具、本地代理工作流以及支持插件的操作。
-
-## 当前状态
-
-- **版本：** `0.1.0`
-- **发布阶段：** 初始公开发布，源码编译分发
-- **主要实现：** 本仓库中的 Rust 工作区
-- **平台焦点：** macOS 和 Linux 开发工作站
-
-## 安装、构建与运行
-
-### 准备工作
-
-- Rust 稳定版工具链
-- Cargo
-- 你想使用的模型的提供商凭据
-
-### 身份验证
-
-兼容 Anthropic 的模型：
-
-```bash
-export ANTHROPIC_API_KEY="..."
-# 使用兼容的端点时可选
-export ANTHROPIC_BASE_URL="https://api.anthropic.com"
-```
-
-Grok 模型：
-
-```bash
-export XAI_API_KEY="..."
-# 使用兼容的端点时可选
-export XAI_BASE_URL="https://api.x.ai"
-```
-
-也可以使用 OAuth 登录：
-
-```bash
-cargo run --bin claw -- login
-```
-
-### 本地安装
-
-```bash
-cargo install --path crates/claw-cli --locked
-```
-
-### 从源码构建
-
-```bash
-cargo build --release -p claw-cli
-```
-
-### 运行
-
-在工作区内运行：
-
-```bash
-cargo run --bin claw -- --help
-cargo run --bin claw --
-cargo run --bin claw -- prompt "总结此工作区"
-cargo run --bin claw -- --model sonnet "审查最新更改"
-```
-
-运行发布版本：
-
-```bash
-./target/release/claw
-./target/release/claw prompt "解释 crates/runtime"
-```
-
-## 支持的功能
-
-- 交互式 REPL 和单次提示执行
-- 已保存会话的检查和恢复流程
-- 内置工作区工具：shell、文件读/写/编辑、搜索、网页获取/搜索、待办事项和笔记本更新
-- 斜杠命令：状态、压缩、配置检查、差异（diff）、导出、会话管理和版本报告
-- 本地代理和技能发现：通过 `claw agents` 和 `claw skills`
-- 通过命令行和斜杠命令界面发现并管理插件
-- OAuth 登录/注销，以及从命令行选择模型/提供商
-- 工作区感知的指令/配置加载（`CLAW.md`、配置文件、权限、插件设置）
-
-## 当前限制
-
-- 目前公开发布**仅限源码构建**；此工作区尚未设置 crates.io 发布
-- GitHub CI 验证 `cargo check`、`cargo test` 和发布构建，但尚未提供自动化的发布打包
-- 当前 CI 目标为 Ubuntu 和 macOS；Windows 的发布就绪性仍待建立
-- 一些实时提供商集成覆盖是可选的，因为它们需要外部凭据 and 网络访问
-- 命令界面可能会在 `0.x` 系列期间继续演进
-
-## 实现现状
-
-Rust 工作区是当前的产品实现。目前包含以下 crate：
-
-- `claw-cli` — 面向用户的二进制文件
-- `api` — 提供商客户端和流式处理
-- `runtime` — 会话、配置、权限、提示词和运行时循环
-- `tools` — 内置工具实现
-- `commands` — 斜杠命令注册和处理程序
-- `plugins` — 插件发现、注册和生命周期支持
-- `lsp` — 语言服务器协议支持类型和进程助手
-- `server` 和 `compat-harness` — 支持服务和兼容性工具
-
-## 路线图
-
-- 发布打包好的构件，用于公共安装
-- 添加可重复的发布工作流和长期维护的变更日志（changelog）规范
-- 将平台验证扩展到当前 CI 矩阵之外
-- 添加更多以任务为中心的示例和操作员文档
-- 继续加强 Rust 实现的功能覆盖并磨炼用户体验（UX）
-
-## 发行版本说明
-
-- 0.1.0 发行说明草案：[`docs/releases/0.1.0.md`](docs/releases/0.1.0.md)

-# Claw Code 0.1.0 发行说明（草案）
-
-## 摘要
-
-Claw Code `0.1.0` 是当前 Rust 实现的第一个公开发布准备里程碑。Claw Code 的灵感来自 Claude Code，并作为一个净室（clean-room）Rust 实现构建；它不是直接的移植或复制。此版本专注于可用的本地 CLI 体验：交互式会话、非交互式提示词、工作区工具、配置加载、会话、插件以及本地代理/技能发现。
-
-## 亮点
-
-- Claw Code 的首个公开 `0.1.0` 发行候选版本
-- 作为当前主要产品界面的安全 Rust 实现
-- 用于交互式和单次编码代理工作流的 `claw` CLI
-- 内置工作区工具：用于 shell、文件操作、搜索、网页获取/搜索、待办事项跟踪和笔记本更新
-- 斜杠命令界面：用于状态、压缩、配置检查、会话、差异/导出以及版本信息
-- 本地插件、代理和技能的发现/管理界面
-- OAuth 登录/注销以及模型/提供商选择
-
-## 安装与运行
-
-此版本目前旨在通过源码构建：
-
-```bash
-cargo install --path crates/claw-cli --locked
-# 或者
-cargo build --release -p claw-cli
-```
-
-运行：
-
-```bash
-claw
-claw prompt "总结此仓库"
-```
-
-## 已知限制
-
-- 仅限源码构建分发；尚未发布打包好的发行构件
-- CI 目前覆盖 Ubuntu 和 macOS 的发布构建、检查和测试
-- Windows 的发布就绪性尚未建立
-- 部分集成覆盖是可选的，因为需要实时提供商凭据和网络访问
-- 公开接口可能会在 `0.x` 版本系列期间继续演进
-
-## 推荐的发行定位
-
-将 `0.1.0` 定位为 Claw Code 当前 Rust 实现的首个公开发布版本，面向习惯于从源码构建的早期采用者。功能表面已足够广泛以支持实际使用，而打包和发布自动化可以在后续版本中继续改进。
-
-## 用于此草案的验证
-
-- 通过 `Cargo.toml` 验证了工作区版本
-- 通过 `cargo metadata` 验证了 `claw` 二进制文件/包路径
-- 通过 `cargo run --quiet --bin claw -- --help` 验证了 CLI 命令表面
-- 通过 `.github/workflows/ci.yml` 验证了 CI 覆盖范围
