-This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
-
-## Project Overview
-
-Claw Code is a local coding-agent CLI tool written in safe Rust. It is a clean-room implementation inspired by Claude Code, providing an interactive REPL, one-shot prompts, workspace-aware tools, local agent workflows, and plugin support. The project name and references throughout use "claw" / "Claw Code".
-
-## Build & Run Commands
-
-```bash
-# Build release binary (produces target/release/claw)
-cargo build --release -p claw-cli
-
-# Run from source (interactive REPL)
-cargo run --bin claw --
-
-# Run one-shot prompt
-cargo run --bin claw -- prompt "summarize this workspace"
-
-# Install locally
-cargo install --path crates/claw-cli --locked
-
-# Run the HTTP server binary
-cargo run --bin claw-server
-```
-
-## Verification Commands
-
-```bash
-# Format check
-cargo fmt
-
-# Lint (workspace-level clippy with deny warnings)
-cargo clippy --workspace --all-targets -- -D warnings
-
-# Run all tests
-cargo test --workspace
-
-# Run tests for a specific crate
-cargo test -p api
-cargo test -p runtime
-
-# Run a single test by name
-cargo test -p <crate> -- <test_name>
-
-# Integration tests in crates/api/tests/ use mock TCP servers (no network needed)
-# One smoke test is #[ignore] — run with: cargo test -p api -- --ignored
-```
-
-## Workspace Architecture
-
-Cargo workspace with `resolver = "2"`. All crates live under `crates/`.
-

-
-### Core Crates
-
-- **`claw-cli`** — User-facing binary (`claw`). REPL loop with markdown rendering (pulldown-cmark + syntect), argument parsing, OAuth flow. Entry point: `crates/claw-cli/src/main.rs`.
-
-- **`runtime`** — Session management, conversation runtime, permissions, system prompt construction, context compaction, MCP stdio management, and hook execution. Key types: `Session` (versioned message history), `ConversationRuntime<C, T>` (generic over `ApiClient` + `ToolExecutor` traits), `PermissionMode`, `McpServerManager`, `HookRunner`.
-
-- **`api`** — HTTP client for LLM providers with SSE streaming. `ClawApiClient` (Anthropic-compatible), `OpenAiCompatClient`, and `Provider` trait. `ProviderKind` enum distinguishes ClawApi, Xai, OpenAi. Request/response types: `MessageRequest`, `StreamEvent`, `ToolDefinition`.
-
-- **`tools`** — Built-in tool definitions and dispatch. `GlobalToolRegistry` is a lazy-static singleton. Tools: Read, Write, Edit, Glob, Grep, Bash, LSP, Task*, Cron*, Worktree*. Each tool has a `ToolSpec` with JSON schema.
-
-- **`commands`** — Slash command registry and handlers (`/help`, `/config`, `/compact`, `/resume`, `/plugins`, `/agents`, `/doctor`, etc.). `SlashCommandSpec` defines each command's name, aliases, description, and category.
-
-- **`plugins`** — Plugin discovery and lifecycle. `PluginManager` loads builtin, bundled, and external (from `~/.claw/plugins/`) plugins. Plugins can provide additional tools via `PluginTool`.
-
-- **`server`** — Axum-based HTTP server (`claw-server`). REST endpoints for session CRUD + SSE event streaming. `AppState` holds shared session store.
-
-- **`lsp`** — Language Server Protocol types and process management for code intelligence features.
-
-- **`compat-harness`** — Extracts command/tool/bootstrap-plan manifests from upstream TypeScript source files (for compatibility tracking). Uses `CLAUDE_CODE_UPSTREAM` env var to locate the upstream repo.
-
-## Key Architectural Patterns
-
-- **Trait-based abstraction**: `ApiClient`, `ToolExecutor`, `Provider` traits enable swappable implementations. `ConversationRuntime` is generic over client and executor.
-- **Static registries**: `GlobalToolRegistry` and slash command specs use lazy-static initialization with compile-time definitions.
-- **SSE streaming**: API responses stream through `MessageStream` (async iterator) to the terminal renderer or server SSE endpoints.
-- **Permission model**: `PermissionMode` enum — ReadOnly, WorkspaceWrite, DangerFullAccess. Configurable via `.claw.json` (`permissions.defaultMode`).
-- **Hook system**: Pre/post tool execution hooks via `HookRunner` in the runtime crate.
-
-## Configuration & Environment
-
-- `.claw.json` — Project-level config (permissions, etc.)
-- `.claw/` — Project directory for hooks, plugins, local settings
-- `~/.claw/` — User-level config directory
-- `.env` — API keys (gitignored): `ANTHROPIC_API_KEY`, `ANTHROPIC_BASE_URL`, `XAI_API_KEY`, `XAI_BASE_URL`
-- `CLAW.md` — Workspace instructions loaded into the system prompt (analogous to CLAUDE.md but for claw itself)
-
-## Lint Rules
-
-- `unsafe_code` is **forbidden** at workspace level
-- Clippy `all` + `pedantic` lints are warnings; some pedantic lints are allowed (`module_name_repetitions`, `missing_panics_doc`, `missing_errors_doc`)
-- CI runs: `cargo check --workspace`, `cargo test --workspace`, `cargo build --release` on Ubuntu and macOS
-
-## Language
-
-Code comments, commit messages, and documentation are primarily in Chinese (中文). UI strings and exported symbol names are in English.

 # 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。
+本项目为不同实现语言和任务目标进行了重构版本，并分布在不同的分支中。
 
-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。

-```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"

-# API 模块 (api)
-
-本模块提供了与大型语言模型 (LLM) 服务提供商（主要是 Anthropic 的 Claude 和兼容 OpenAI 的服务）进行交互的高层抽象和客户端。
-
-## 概览
-
-`api` 模块负责以下职责：
-- 标准化与不同 AI 提供商的通信。
-- 通过服务器发送事件 (SSE) 处理流式响应。
-- 管理身份验证源（API 密钥、OAuth 令牌）。
-- 提供消息、工具和使用情况跟踪的共享数据结构。
-
-## 关键特性
-
-- **提供商抽象 (Provider Abstraction)**：支持多种 AI 后端，包括：
-  - `ClawApiClient`: Claude 模型的主要提供商。
-  - `OpenAiCompatClient`: 支持兼容 OpenAI 的 API（如本地模型、专门的提供商）。
-- **流式支持 (Streaming Support)**：健壮的 SSE 解析实现 (`SseParser`)，用于处理实时的内容生成。
-- **工具集成 (Tool Integration)**：为 `ToolDefinition`、`ToolChoice` 和 `ToolResultContentBlock` 提供强类型定义，支持智能代理 (Agentic) 工作流。
-- **身份验证管理 (Auth Management)**：用于解析启动身份验证源和管理 OAuth 令牌的实用工具。
-- **模型智能 (Model Intelligence)**：解析模型别名和计算最大标记 (Token) 限制的元数据及辅助函数。
-
-## 实现逻辑
-
-### 核心模块
-
-- **`client.rs`**: 定义了 `ProviderClient` 特性 (Trait) 和基础客户端逻辑。它使用 `reqwest` 处理 HTTP 请求，并管理消息流的生命周期。
-- **`types.rs`**: 包含 API 的核心数据模型，如 `InputMessage`、`OutputContentBlock` 以及 `MessageRequest`/`MessageResponse`。
-- **`sse.rs`**: 实现了一个状态化的 SSE 解析器，能够处理分段的数据块并发出类型化的 `StreamEvent`。
-- **`providers/`**: 包含针对不同 LLM 端点的特定逻辑，将它们的独特格式映射到本模块使用的共享类型。
-
-### 数据流
-
-1. 构建包含模型详情、消息和工具定义的 `MessageRequest`。
-2. `ApiClient` 将此请求转换为提供商特定的 HTTP 请求。
-3. 如果启用了流式传输，客户端返回一个 `MessageStream`，该流使用 `SseParser` 来产生 `StreamEvent`。
-4. 最终响应包含用于跟踪 Token 消耗的 `Usage` 信息。
-
-## 使用示例
-
-```rust
-use api::{ApiClient, MessageRequest, InputMessage};
-
-// 示例初始化（已简化）
-let client = ApiClient::new(auth_source);
-let request = MessageRequest {
-    model: "claude-3-5-sonnet-20241022".to_string(),
-    messages: vec![InputMessage::user("你好，世界！")],
-    ..Default::default()
-};
-
-let stream = client.create_message_stream(request).await?;
-```

-# Claw CLI 模块 (claw-cli)
-
-本模块实现了 Claw 应用程序的主要命令行界面 (CLI)。它提供了交互式的 REPL 环境和非交互式的命令执行功能。
-
-## 概览
-
-`claw-cli` 模块是整个项目的“胶水”，负责编排 `runtime`、`api`、`tools` 和 `plugins` 模块之间的交互。它捕获用户输入，管理应用程序状态，并以用户友好的格式渲染 AI 响应。
-
-## 关键特性
-
-- **交互式 REPL**：一个功能齐全的 Read-Eval-Print Loop，用于与 AI 对话，支持：
-  - 通过 `rustyline` 实现多行输入和命令历史。
-  - 实时的 Markdown 流式显示和代码语法高亮。
-  - 为耗时的工具调用显示动态的加载动画 (Spinner) 和进度指示器。
-- **子命令**：
-  - `prompt`：运行单次 Prompt 并退出（单次模式）。
-  - `login`/`logout`：处理与 Claw 平台的 OAuth 身份验证。
-  - `init`：初始化新项目/仓库以配合 Claw 使用。
-  - `resume`：恢复并继续之前的对话会话。
-  - `agents`/`skills`：管理并发现可用的智能体和技能。
-- **权限管理**：对工具执行权限的细粒度控制：
-  - `read-only`：安全的分析模式。
-  - `workspace-write`：允许在当前工作区内进行修改。
-  - `danger-full-access`：高级任务的无限制访问。
-- **OAuth 流程**：集成了本地 HTTP 服务器，无缝处理用户机器上的 OAuth 回调重定向。
-
-## 实现逻辑
-
-### 核心模块
-
-- **`main.rs`**: 主要入口点。负责解析命令行参数、初始化环境，并调度到适当的操作（REPL 或子命令）。
-- **`render/`**: 包含 `TerminalRenderer` 和 Markdown 流渲染逻辑。使用 `syntect` 进行语法高亮，并使用 `crossterm` 进行终端操作。
-- **`input/`**: 处理用户输入捕获，包括对多行 Prompt 和斜杠命令 (Slash Command) 的特殊处理。
-- **`init.rs`**: 处理项目级初始化和仓库设置。
-
-### 交互循环流程
-
-1. CLI 初始化 `ConversationRuntime` 并加载项目上下文。
-2. 使用 `rustyline` 进入捕获用户输入的循环。
-3. 检查用户输入是否为“斜杠命令”（如 `/compact`、`/model`）。
-4. 普通 Prompt 通过 `runtime` 发送给 AI。
-5. AI 事件（文本增量、工具调用）逐步渲染到终端。
-6. 会话定期保存，以便将来可以恢复。
-
-## 使用方法
-
-主二进制程序名为 `claw`。
-
-```bash
-# 启动交互式 REPL
-claw
-
-# 运行单次 Prompt
-claw prompt "解释一下这个项目的架构"
-
-# 登录服务
-claw login
-```

-# 命令模块 (commands)
-
-本模块负责定义和管理 Claw 交互界面中使用的“斜杠命令”(Slash Commands)，并提供相关的解析和执行逻辑。
-
-## 概览
-
-`commands` 模块的主要职责包括：
-- 定义所有可用的斜杠命令及其元数据（别名、说明、类别等）。
-- 提供命令注册表 (`CommandRegistry`)，用于在 CLI 中发现和分发命令。
-- 实现复杂的管理命令，如插件管理 (`/plugins`)、智能体查看 (`/agents`) 和技能查看 (`/skills`)。
-- 提供命令建议功能，支持基于编辑距离 (Levenshtein distance) 的模糊匹配。
-
-## 关键特性
-
-- **斜杠命令规范 (SlashCommandSpec)**：每个命令都包含详尽的元数据，包括所属类别（核心、工作区、会话、Git、自动化）以及是否支持在恢复会话时执行。
-- **命令分类**：
-  - **核心 (Core)**：`/help`, `/status`, `/model`, `/permissions`, `/cost` 等。
-  - **工作区 (Workspace)**：`/config`, `/memory`, `/diff`, `/teleport` 等。
-  - **会话 (Session)**：`/clear`, `/resume`, `/export`, `/session` 等。
-  - **Git 交互**：`/branch`, `/commit`, `/pr`, `/issue` 等。
-  - **自动化 (Automation)**：`/plugins`, `/agents`, `/skills`, `/ultraplan` 等。
-- **模糊匹配与建议**：当用户输入错误的命令时，系统会自动推荐最接近的合法命令。
-- **插件集成**：`/plugins` 命令允许用户动态安装、启用、禁用或卸载插件，并能通知运行时重新加载环境。
-
-## 实现逻辑
-
-### 核心模块
-
-- **`lib.rs`**: 包含了绝大部分逻辑。
-  - **`SlashCommand` 枚举**: 定义了所有命令的强类型表示。
-  - **`SlashCommandSpec` 结构体**: 存储命令的静态配置信息。
-  - **`handle_plugins_slash_command`**: 处理复杂的插件管理工作流。
-  - **`suggest_slash_commands`**: 实现基于 Levenshtein 距离的建议算法。
-
-### 工作流程
-
-1. 用户在 REPL 中输入以 `/` 开头的字符串。
-2. `claw-cli` 调用 `SlashCommand::parse` 进行解析。
-3. 解析后的命令被分发到相应的处理器。
-4. 处理结果（通常包含要显示给用户的消息，以及可选的会话更新或运行时重新加载请求）返回给 CLI。
-
-## 使用示例 (内部)
-
-```rust
-use commands::{SlashCommand, suggest_slash_commands};
-
-// 解析命令
-if let Some(cmd) = SlashCommand::parse("/model sonnet") {
-    // 处理模型切换逻辑
-}
-
-// 获取建议
-let suggestions = suggest_slash_commands("hpel", 3);
-// 返回 ["/help"]
-```

-# 兼容性测试套件模块 (compat-harness)
-
-本模块提供了一套工具，专门用于分析和提取上游引用实现（如原始的 `claude-code` TypeScript 源码）中的元数据，以确保 Rust 版本的实现与其保持功能兼容。
-
-## 概览
-
-`compat-harness` 的主要职责是：
-- 定位上游仓库的源码路径。
-- 从 TypeScript 源码文件中提取命令 (`commands`)、工具 (`tools`) 和启动阶段 (`bootstrap phases`) 的定义。
-- 自动生成功能清单 (`ExtractedManifest`)，供运行时或测试使用，以验证 Rust 版本的覆盖率。
-
-## 关键特性
-
-- **上游路径解析 (UpstreamPaths)**：能够自动识别多种常见的上游仓库目录结构，并支持通过环境变量 `CLAUDE_CODE_UPSTREAM` 进行覆盖。
-- **静态代码分析**：通过解析 TypeScript 源码，识别特定的代码模式（如 `export const INTERNAL_ONLY_COMMANDS` 或基于 `feature()` 的功能开关）。
-- **清单提取 (Manifest Extraction)**：
-  - **命令提取**：识别内置命令、仅限内部使用的命令以及受功能开关控制的命令。
-  - **工具提取**：识别基础工具和条件加载的工具。
-  - **启动计划提取**：分析 CLI 入口文件，重建启动时的各个阶段（如 `FastPathVersion`, `MainRuntime` 等）。
-
-## 实现逻辑
-
-### 核心模块
-
-- **`lib.rs`**: 包含了核心的提取逻辑。
-  - **`UpstreamPaths` 结构体**: 封装了寻找 `commands.ts`、`tools.ts` 和 `cli.tsx` 的逻辑。
-  - **`extract_commands` & `extract_tools`**: 使用字符串解析技术，识别 TypeScript 的 `import` 和赋值操作，提取符号名称。
-  - **`extract_bootstrap_plan`**: 搜索特定的标志性字符串（如 `--version` 或 `daemon-worker`），从而推断出上游程序的启动流程。
-
-### 工作流程
-
-1. 模块根据预设路径或环境变量寻找上游 `claude-code` 仓库。
-2. 读取关键的 `.ts` 或 `.tsx` 文件内容。
-3. 执行正则表达式风格的行解析，提取出所有定义的命令和工具名称。
-4. 将提取结果组织成 `ExtractedManifest` 对象。
-
-## 使用示例 (内部测试)
-
-```rust
-use compat_harness::{UpstreamPaths, extract_manifest};
-
-// 指定工作区目录，自动寻找上游路径
-let paths = UpstreamPaths::from_workspace_dir("path/to/workspace");
-// 提取功能清单
-if let Ok(manifest) = extract_manifest(&paths) {
-    println!("上游发现 {} 个工具", manifest.tools.entries().len());
-}
-```

-# LSP 模块 (lsp)
-
-本模块实现了语言服务协议 (Language Server Protocol, LSP) 的客户端功能，允许系统通过集成的编程语言服务器获取代码的语义信息、错误诊断和符号导航。
-
-## 概览
-
-`lsp` 模块的主要职责是：
-- 管理多个 LSP 服务器的生命周期（启动、初始化、关闭）。
-- 与服务器进行异步 JSON-RPC 通信。
-- 提供跨语言的代码智能功能，如：
-  - **转到定义 (Go to Definition)**
-  - **查找引用 (Find References)**
-  - **工作区诊断 (Workspace Diagnostics)**
-- 为 AI 提示词 (Prompt) 提供上下文增强，将代码中的实时错误和符号关系反馈给 LLM。
-
-## 关键特性
-
-- **LspManager**: 核心管理类，负责协调不同语言的服务器配置和文档状态。
-- **上下文增强 (Context Enrichment)**：定义了 `LspContextEnrichment` 结构，能够将复杂的 LSP 响应（如诊断信息和定义）转换为易于 AI 理解的 Markdown 格式。
-- **多服务器支持**：支持根据文件扩展名将请求路由到不同的语言服务器（如 `rust-analyzer`, `pyright` 等）。
-- **同步机制**：处理文档的 `didOpen`、`didChange` 和 `didSave` 消息，确保服务器拥有最新的代码视图。
-
-## 实现逻辑
-
-### 核心模块
-
-- **`manager.rs`**: 实现了 `LspManager`。它维护一个服务器池，并提供高层 API 来执行跨服务器的请求。
-- **`client.rs`**: 实现底层的 LSP 客户端逻辑，处理基于 `tokio` 的异步 I/O 和 JSON-RPC 消息的分帧与解析。
-- **`types.rs`**: 定义了本模块使用的专用数据类型，并对 `lsp-types` 库中的类型进行了简化和包装，以便于内部使用。
-- **`error.rs`**: 定义了 LSP 相关的错误处理。
-
-### 工作流程
-
-1. 系统根据配置初始化 `LspManager`。
-2. 当打开一个文件时，`LspManager` 启动相应的服务器并发送 `initialize` 请求。
-3. `LspManager` 跟踪文档的打开状态，并在内容变化时同步到服务器。
-4. 当需要对某个符号进行分析时，调用 `go_to_definition` 等方法，模块负责发送请求并解析返回的 `Location`。
-5. 诊断信息异步通过 `textDocument/publishDiagnostics` 通知到达，模块会缓存这些信息供后续查询。
-
-## 使用示例 (内部)
-
-```rust
-use lsp::{LspManager, LspServerConfig};
-
-// 配置并初始化管理器
-let configs = vec![LspServerConfig {
-    name: "rust-analyzer".to_string(),
-    command: "rust-analyzer".to_string(),
-    ..Default::default()
-}];
-let manager = LspManager::new(configs)?;
-
-// 获取某个位置的上下文增强信息
-let enrichment = manager.context_enrichment(&file_path, position).await?;
-println!("{}", enrichment.render_prompt_section());
-```

-# 插件模块 (plugins)
-
-本模块实现了 Claw 的插件系统，允许通过外部扩展来增强 AI 的功能，包括自定义工具、命令以及在工具执行前后运行的钩子 (Hooks)。
-
-## 概览
-
-`plugins` 模块的主要职责是：
-- 定义插件的清单格式 (`plugin.json`) 和元数据结构。
-- 管理插件的完整生命周期：安装、加载、初始化、启用/禁用、更新和卸载。
-- 提供插件类型的抽象：
-  - **Builtin (内置)**：编译在程序内部的插件。
-  - **Bundled (绑定)**：随应用程序分发但作为独立文件存在的插件。
-  - **External (外部)**：用户自行安装或从远程仓库下载的插件。
-- 实现插件隔离与执行机制，支持插件定义的自定义工具。
-
-## 关键特性
-
-- **插件清单 (PluginManifest)**：每个插件必须包含一个 `plugin.json`，详细说明其名称、版本、所需权限、钩子、生命周期脚本以及它所暴露的工具。
-- **自定义工具 (PluginTool)**：插件可以定义全新的工具供 AI 调用。这些工具在执行时被作为独立的外部进程启动。
-- **钩子系统 (Hooks)**：支持 `PreToolUse` 和 `PostToolUse` 钩子，允许插件在 AI 调用任何工具之前或之后执行特定的逻辑。
-- **生命周期管理**：提供 `Init` 和 `Shutdown` 阶段，允许插件在加载时进行环境准备，在卸载或关闭时进行清理。
-- **权限模型**：强制要求插件声明权限（`read`, `write`, `execute`），并为定义的工具指定安全级别（`read-only`, `workspace-write`, `danger-full-access`）。
-
-## 实现逻辑
-
-### 核心模块
-
-- **`lib.rs`**: 包含了插件定义的各种结构体（Manifest, Metadata, Tool, Permission 等）以及插件特性的定义。
-- **`manager.rs`**: 实现了 `PluginManager`，负责插件在磁盘上的组织、注册表的维护以及安装/更新逻辑。
-- **`hooks.rs`**: 实现了钩子执行器 (`HookRunner`)，负责在正确的时机触发插件定义的脚本。
-
-### 插件加载与执行流程
-
-1. `PluginManager` 扫描指定的目录（内置、绑定及外部安装目录）。
-2. 读取并验证每个插件的 `plugin.json`。
-3. 如果插件被启用，则初始化该插件并将其定义的工具注册到系统的全局工具注册表中。
-4. 当 AI 调用插件工具时，系统根据清单中定义的命令行信息启动一个子进程，并通过标准输入/环境变量传递参数。
-5. 钩子逻辑会在工具执行的生命周期内被自动触发。
-

-# 运行时模块 (runtime)
-
-本模块是 Claw 的核心引擎，负责协调 AI 模型、工具执行、会话管理和权限控制之间的所有交互。
-
-## 概览
-
-`runtime` 模块是整个系统的“中枢神经”，其主要职责包括：
-- **对话驱动**：管理“用户-助手-工具”的循环迭代。
-- **会话持久化**：负责会话的加载、保存及历史记录的压缩 (Compaction)。
-- **MCP 客户端**：实现模型上下文协议 (Model Context Protocol)，支持与外部 MCP 服务器通信。
-- **安全沙箱与权限**：实施基于策略的工具执行权限检查。
-- **上下文构建**：动态生成系统提示词 (System Prompt)，集成工作区上下文。
-- **消耗统计**：精确跟踪 Token 使用情况和 Token 缓存状态。
-
-## 关键特性
-
-- **ConversationRuntime**：核心驱动类，支持流式响应处理和多轮工具调用迭代。
-- **权限引擎 (Permissions)**：提供多种模式（`ReadOnly`, `WorkspaceWrite`, `DangerFullAccess`），并支持交互式权限确认。
-- **会话压缩 (Compaction)**：当对话历史过长影响性能或成本时，自动将旧消息总结为摘要，保持上下文精简。
-- **钩子集成 (Hooks)**：在工具执行的前后触发插件定义的钩子，支持干预工具输入或处理执行结果。
-- **沙箱执行 (Sandbox)**：为 Bash 等敏感工具提供受限的执行环境。
-
-## 实现逻辑
-
-### 核心子模块
-
-- **`conversation.rs`**: 定义了核心的 `ConversationRuntime` 和 `ApiClient`/`ToolExecutor` 特性。
-- **`mcp_stdio.rs` / `mcp_client.rs`**: 实现了完整的 MCP 规范，支持通过标准输入/输出与外部工具服务器交互。
-- **`session.rs`**: 定义了消息模型 (`ConversationMessage`)、内容块 (`ContentBlock`) 和会话序列化逻辑。
-- **`permissions.rs`**: 实现了权限审核逻辑和提示器接口。
-- **`compact.rs`**: 包含了基于 LLM 的会话摘要生成和历史裁剪算法。
-- **`config.rs`**: 负责加载和合并多层级的配置文件。
-
-### 对话循环流程 (run_turn)
-
-1. 将用户输入推入 `Session`。
-2. 调用 `ApiClient` 发起流式请求。
-3. 监听 `AssistantEvent`，解析文本内容和工具调用请求。
-4. **工具权限审核**：针对每个 `ToolUse`，根据 `PermissionPolicy` 决定是允许、拒绝还是询问用户。
-5. **执行工具**：若允许，则通过 `ToolExecutor`（或 MCP 客户端）执行工具，并运行相关的 `Pre/Post Hooks`。
-6. 将工具结果反馈给 AI，进入下一轮迭代，直到 AI 给出最终回复。
-
-## 使用示例 (内部)
-
-```rust
-use runtime::{ConversationRuntime, Session, PermissionPolicy, PermissionMode};
-
-// 初始化运行时
-let mut runtime = ConversationRuntime::new(
-    Session::new(),
-    api_client,
-    tool_executor,
-    PermissionPolicy::new(PermissionMode::WorkspaceWrite),
-    system_prompt,
-);
-
-// 运行一轮对话
-let summary = runtime.run_turn("帮我重构 src/lib.rs", Some(&mut cli_prompter))?;
-println!("共迭代 {} 次，消耗 {} tokens", summary.iterations, summary.usage.total_tokens());
-```

-# Rusty Claude CLI 模块 (rusty-claude-cli)
-
-本模块提供了 Claw 命令行界面的另一个功能完整的实现。它集成了对话、工具执行、插件扩展以及身份验证等核心功能。
-
-## 概览
-
-`rusty-claude-cli` 是一个全功能的 CLI 应用程序，其主要职责包括：
-- **用户交互**：提供交互式 REPL 和非交互式命令执行（`prompt` 子命令）。
-- **环境初始化**：处理项目初始化 (`init`) 和配置加载。
-- **身份验证**：通过本地回环服务器处理 OAuth 登录流程。
-- **状态渲染**：实现丰富的终端 UI 效果，如 Markdown 渲染、语法高亮和动态加载动画 (Spinner)。
-- **会话管理**：支持从保存的文件中恢复会话并执行追加的斜杠命令。
-
-## 与 `claw-cli` 的关系
-
-虽然 `rusty-claude-cli` 和 `claw-cli` 都生成名为 `claw` 的二进制文件，但 `rusty-claude-cli` 包含更复杂的集成逻辑：
-- 它直接引用了几乎所有的核心 crate（`runtime`, `api`, `tools`, `plugins`, `commands`）。
-- 它的 `main.rs` 实现非常庞大，包含了大量的业务编排逻辑。
-- 它可以作为一个独立的、集成度极高的 CLI 参考实现。
-
-## 关键特性
-
-- **多功能子命令**：
-  - `prompt`：快速运行单次推理。
-  - `login`/`logout`：OAuth 身份验证管理。
-  - `init`：项目环境自举。
-  - `bootstrap-plan`：查看系统的启动阶段。
-  - `dump-manifests`：从上游源码中提取并显示功能清单。
-- **增强的 REPL**：
-  - 支持多行输入和历史记录。
-  - 集成了斜杠命令处理引擎。
-  - 提供详细的消耗统计和权限模式切换报告。
-- **灵活的权限控制**：支持通过命令行参数 `--permission-mode` 或环境变量动态调整权限级别。
-
-## 实现逻辑
-
-### 核心子模块
-
-- **`main.rs`**: 程序的入口，包含了复杂的参数解析逻辑和 REPL 循环。
-- **`render.rs`**: 封装了 `TerminalRenderer` 和 `Spinner`，负责所有的终端输出美化。
-- **`input.rs`**: 处理从标准输入读取数据及命令解析。
-- **`init.rs`**: 专注于仓库的初始化和 `.claw.md` 文件的生成。
-- **`app.rs`**: 可能包含应用程序级别的高层状态管理（取决于具体实现）。
-
-### 工作流程
-
-1. 程序启动，解析命令行参数。
-2. 根据参数决定是执行单次任务还是进入 REPL 模式。
-3. 在 REPL 模式下，初始化 `ConversationRuntime`。
-4. 进入循环：读取用户输入 -> 处理斜杠命令或发送给 AI -> 渲染响应 -> 执行工具 -> 循环。
-5. 会话数据根据需要保存或恢复。
-
-## 使用示例
-
-```bash
-# 启动交互模式
-cargo run -p rusty-claude-cli --bin claw
-
-# 直接运行 Prompt
-cargo run -p rusty-claude-cli --bin claw prompt "检查代码中的内存泄漏"
-
-# 恢复之前的会话并执行压缩
-cargo run -p rusty-claude-cli --bin claw --resume session.json /compact
-```

-# 服务模块 (server)
-
-本模块提供了一个基于 HTTP 的 RESTful API 和 Server-Sent Events (SSE) 流接口，允许通过网络远程管理和与 Claw 会话进行交互。
-
-## 概览
-
-`server` 模块将 `runtime` 的核心功能封装为 Web 服务，其主要职责包括：
-- **会话管理**：提供创建、列出和获取会话详情的端点。
-- **消息分发**：接收用户消息并将其路由到相应的会话实例。
-- **实时流推送**：通过 SSE 接口实时推送会话事件（如 AI 响应消息、状态快照）。
-- **状态维护**：在内存中管理多个活跃会话的生命周期。
-
-## 关键特性
-
-- **RESTful API**：使用 `axum` 框架实现，遵循现代 Web 服务标准。
-- **事件流 (SSE)**：支持 `text/event-stream`，允许客户端实时订阅会话更新。
-- **并发处理**：利用 `tokio` 和 `broadcast` 频道，支持多个客户端同时监听同一会话的事件。
-- **快照机制**：在建立连接时发送当前会话的完整快照，确保客户端能够同步历史状态。
-
-## 实现逻辑
-
-### 核心接口 (API Routes)
-
-- `POST /sessions`: 创建一个新的对话会话。
-- `GET /sessions`: 列出所有活跃会话的简要信息。
-- `GET /sessions/{id}`: 获取指定会话的完整详细信息。
-- `POST /sessions/{id}/message`: 向指定会话发送一条新消息。
-- `GET /sessions/{id}/events`: 建立 SSE 连接，订阅该会话的实时事件流。
-
-### 核心结构
-
-- **`AppState`**: 存储全局状态，包括 `SessionStore` (由 `RwLock` 保护的哈希表) 和会话 ID 分配器。
-- **`Session`**: 封装了 `runtime::Session` 实例，并包含一个用于广播事件的 `broadcast::Sender`。
-- **`SessionEvent`**: 定义了流中传输的事件类型，包括 `Snapshot` (快照) 和 `Message` (新消息)。
-
-### 工作流程
-
-1. 启动服务并初始化 `AppState`。
-2. 客户端通过 `POST /sessions` 开启一个新会话。
-3. 客户端连接 `GET /sessions/{id}/events` 以监听响应。
-4. 客户端通过 `POST /sessions/{id}/message` 发送 Prompt。
-5. 服务端将消息存入 `runtime::Session`，并触发广播。SSE 流将该消息及后续的 AI 响应实时推送回客户端。
-
-## 使用示例 (内部)
-
-```rust
-use server::{app, AppState};
-use axum::Router;
-
-// 创建应用路由
-let state = AppState::new();
-let router = app(state);
-
-// 启动服务（示例）
-let listener = tokio::net::TcpListener::bind("0.0.0.0:3000").await.unwrap();
-axum::serve(listener, router).await.unwrap();
-```

-# 工具规范模块 (tools)
-
-本模块定义了 AI 代理可以使用的所有内置工具的规范 (Schema)、权限要求以及分发逻辑。
-
-## 概览
-
-`tools` 模块充当了 AI 认知能力与物理操作之间的桥梁，其主要职责包括：
-- **工具定义**：使用 JSON Schema 定义每个工具的输入参数结构，以便 AI 正确调用。
-- **权限映射**：为每个工具分配安全等级（如只读、工作区写入、完全访问）。
-- **工具注册表 (GlobalToolRegistry)**：统一管理内置工具和由插件提供的动态工具。
-- **分发执行**：将 AI 生成的 JSON 调用分发到 `runtime` 模块中的具体实现。
-
-## 关键特性
-
-- **内置工具集 (MVP Tools)**：
-  - **系统交互**：`bash`, `PowerShell`, `REPL`。
-  - **文件操作**：`read_file`, `write_file`, `edit_file`。
-  - **搜索与发现**：`glob_search`, `grep_search`, `ToolSearch`。
-  - **网络与辅助**：`WebSearch`, `WebFetch`, `Sleep`。
-  - **高级调度**：`Agent`（启动子代理）, `Skill`（加载专用技能）, `TodoWrite`（任务管理）。
-- **名称归一化**：支持工具别名（例如将 `grep` 映射为 `grep_search`），提高 AI 调用的稳健性。
-- **插件集成**：允许 `plugins` 模块注册自定义工具，并确保它们与内置工具不发生命名冲突。
-
-## 实现逻辑
-
-### 核心结构
-
-- **`ToolSpec`**: 核心配置结构，存储工具的元数据（名称、描述、Schema、权限）。
-- **`GlobalToolRegistry`**: 负责维护工具列表，并提供 `definitions` 方法生成供 LLM 使用的工具 API 声明。
-- **`execute_tool`**: 顶级分发函数，负责将反序列化后的输入传递给底层的执行函数。
-
-### 工作流程
-
-1. 系统初始化时，根据用户配置和加载的插件，构建 `GlobalToolRegistry`。
-2. 将工具定义转换为 AI 模型可理解的格式（由 `api` 模块处理）。
-3. 当接收到 AI 的工具调用请求时，`runtime::ConversationRuntime` 调用 `ToolExecutor`。
-4. `ToolExecutor` 委托给本模块的 `execute_tool` 函数。
-5. 本模块验证输入格式，并调用 `runtime` 提供的底层文件或进程操作 API。
-
-## 使用示例 (工具定义)
-
-```rust
-use tools::{ToolSpec, mvp_tool_specs};
-use serde_json::json;
-
-// 获取所有 MVP 工具的规范
-let specs = mvp_tool_specs();
-for spec in specs {
-    println!("工具: {}, 权限级别: {:?}", spec.name, spec.required_permission);
-}

-# 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
