+# Qwen Code CLI LSP 集成实现方案分析
+
+## 1. 项目概述
+
+本方案旨在将 LSP（Language Server Protocol）能力原生集成到 Qwen Code CLI 中，使 AI 代理能够利用代码导航、定义查找、引用查找等功能。LSP 将作为与 MCP 并行的一级扩展机制实现。
+
+## 2. 技术方案对比
+
+### 2.1 Piebald-AI/claude-code-lsps 方案
+- **架构**: 客户端直接与每个 LSP 通信，通过 `.lsp.json` 配置文件声明服务器命令/参数、stdio 传输和文件扩展名路由
+- **用户配置**: 低摩擦，只需放置 `.lsp.json` 配置并确保 LSP 二进制文件已安装
+- **安全**: LSP 子进程以用户权限运行，无内置信任门控
+- **功能覆盖**: 可以暴露完整的 LSP 表面（hover、诊断、代码操作、重命名等）
+
+### 2.2 原生 LSP 客户端方案（推荐方案）
+- **架构**: Qwen Code CLI 直接作为 LSP 客户端，与语言服务器建立 JSON-RPC 连接
+- **用户配置**: 支持内置预设 + 用户自定义 `.lsp.json` 配置
+- **安全**: 与 MCP 共享相同的安全控制（信任工作区、允许/拒绝列表、确认提示）
+- **功能覆盖**: 暴露完整的 LSP 功能（流式诊断、代码操作、重命名、语义标记等）
+
+### 2.3 cclsp + MCP 方案（备选）
+- **架构**: 通过 MCP 协议调用 cclsp 作为 LSP 桥接
+- **用户配置**: 需要 MCP 配置
+- **安全**: 通过 MCP 安全控制
+- **功能覆盖**: 依赖于 cclsp 映射的 MCP 工具
+
+## 3. 原生 LSP 集成详细计划
+
+### 3.1 方案选择
+- **推荐方案**: 原生 LSP 客户端作为主要路径，因为它提供完整 LSP 功能、更低延迟和更好的用户体验
+- **兼容层**: 保留 cclsp+MCP 作为现有 MCP 工作流的兼容桥接
+- **并行架构**: LSP 和 MCP 作为独立的扩展机制共存，共享安全策略
+
+### 3.2 实现步骤
+
+#### 3.2.1 创建原生 LSP 服务
+在 `packages/cli/src/services/lsp/` 目录下创建 `NativeLspService` 类，处理：
+- 工作区语言检测
+- 自动发现和启动语言服务器
+- 与现有文档/编辑模型同步
+- LSP 能力直接暴露给代理
+
+#### 3.2.2 配置支持
+- 支持内置预设配置（常见语言服务器）
+- 支持用户自定义 `.lsp.json` 配置文件
+- 与 MCP 配置共存，共享信任控制
+
+#### 3.2.3 集成启动流程
+- 在 `packages/cli/src/config/config.ts` 中的 `loadCliConfig` 函数内集成
+- 确保 LSP 服务与 MCP 服务共享相同的安全控制机制
+- 处理沙箱预检和主运行的重复调用问题
+
+#### 3.2.4 功能标志配置
+- 在 `packages/cli/src/config/settingsSchema.ts` 中添加新的设置项
+- 提供全局开关（如 `lsp.enabled=false`）允许用户禁用 LSP 功能
+- 尊重 `mcp.allowed`/`mcp.excluded` 和文件夹信任设置
+
+#### 3.2.5 安全控制
+- 与 MCP 共享相同的安全控制机制
+- 在信任工作区中自动启用，在非信任工作区中提示用户
+- 实现路径允许列表和进程启动确认
+
+#### 3.2.6 错误处理与用户通知
+- 检测缺失的语言服务器并提供安装命令
+- 通过现有 MCP 状态 UI 显示错误信息
+- 实现重试/退避机制，检测沙箱环境并抑制自动启动
+
+### 3.3 需要确认的不确定项
+
+1. **启动集成点**：在 `loadCliConfig` 中集成原生 LSP 服务，需确保与 MCP 服务的协调
+
+2. **配置优先级**：如果用户已有 cclsp MCP 配置，应保持并存还是优先使用原生 LSP
+
+3. **功能开关设计**：开关应该是全局级别的，LSP 和 MCP 可独立启用/禁用
+
+4. **共享安全模型**：如何在代码中复用 MCP 的信任/安全控制逻辑
+
+5. **语言服务器管理**：如何管理 LSP 服务器生命周期并与文档编辑模型同步
+
+6. **依赖检测机制**：检测 LSP 服务器可用性，失败时提供降级选项
+
+7. **测试策略**：需要测试 LSP 与 MCP 的并行运行，以及共享安全控制
+
+### 3.4 安全考虑
+
+- 与 MCP 共享相同的安全控制模型
+- 仅在受信任工作区中启用自动 LSP 功能
+- 提供用户确认机制用于启动新的 LSP 服务器
+- 防止路径劫持，使用安全的路径解析
+
+### 3.5 高级 LSP 功能支持
+
+- **完整 LSP 功能**: 支持流式诊断、代码操作、重命名、语义高亮、工作区编辑等
+- **兼容 Claude 配置**: 支持导入 Claude Code 风格的 `.lsp.json` 配置
+- **性能优化**: 优化 LSP 服务器启动时间和内存使用
+
+### 3.6 用户体验
+
+- 提供安装提示而非自动安装
+- 在统一的状态界面显示 LSP 和 MCP 服务器状态
+- 提供独立开关让用户控制 LSP 和 MCP 功能
+- 为只读/沙箱环境提供安全的配置处理和清晰的错误消息
+
+## 4. 实施总结
+
+### 4.1 已完成的工作
+1. **NativeLspService 类**：创建了核心服务类，包含语言检测、配置合并、LSP 连接管理等功能
+2. **LSP 连接工厂**：实现了基于 stdio 的 LSP 连接创建和管理
+3. **语言检测机制**：实现了基于文件扩展名和项目配置文件的语言自动检测
+4. **配置系统**：实现了内置预设、用户配置和 Claude 兼容配置的合并
+5. **安全控制**：实现了与 MCP 共享的安全控制机制，包括信任检查、用户确认、路径安全验证
+6. **CLI 集成**：在 `loadCliConfig` 函数中集成了 LSP 服务初始化点
+
+### 4.2 关键组件
+
+#### 4.2.1 LspConnectionFactory
+- 使用 `vscode-jsonrpc` 和 `vscode-languageserver-protocol` 实现 LSP 连接
+- 支持 stdio 传输方式，可以扩展支持 TCP 传输
+- 提供连接创建、初始化和关闭的完整生命周期管理
+
+#### 4.2.2 NativeLspService
+- **语言检测**：扫描项目文件和配置文件来识别编程语言
+- **配置合并**：按优先级合并内置预设、用户配置和兼容层配置
+- **LSP 服务器管理**：启动、停止和状态管理
+- **安全控制**：与 MCP 共享的信任和确认机制
+
+#### 4.2.3 配置架构
+- **内置预设**：为常见语言提供默认 LSP 服务器配置
+- **用户配置**：支持 `.lsp.json` 文件格式
+- **Claude 兼容**：可导入 Claude Code 的 LSP 配置
+
+### 4.3 依赖管理
+- 使用 `vscode-languageserver-protocol` 进行 LSP 协议通信
+- 使用 `vscode-jsonrpc` 进行 JSON-RPC 消息传递
+- 使用 `vscode-languageserver-textdocument` 管理文档版本
+
+### 4.4 安全特性
+- 工作区信任检查
+- 用户确认机制（对于非信任工作区）
+- 命令存在性验证
+- 路径安全性检查
+
+## 5. 总结
+
+原生 LSP 客户端是当前最符合 Qwen Code 架构的选择，它提供了完整的 LSP 功能、更低的延迟和更好的用户体验。LSP 作为与 MCP 并行的一级扩展机制，将与 MCP 共享安全控制策略，但提供更丰富的代码智能功能。cclsp+MCP 可作为兼容层保留，以支持现有的 MCP 工作流。
+
+该实现方案将使 Qwen Code CLI 具备完整的 LSP 功能，包括代码跳转、引用查找、自动补全、代码诊断等，为 AI 代理提供更丰富的代码理解能力。

+# LSP 调试指南
+
+本指南介绍如何调试 packages/cli 中的 LSP (Language Server Protocol) 功能。
+
+## 1. 启用调试模式
+
+CLI 支持调试模式，可以提供额外的日志信息：
+
+```bash
+# 使用 debug 标志运行
+qwen --debug [你的命令]
+
+# 或设置环境变量
+DEBUG=true qwen [你的命令]
+DEBUG_MODE=true qwen [你的命令]
+```
+
+## 2. LSP 配置选项
+
+LSP 功能通过设置系统配置，包含以下选项：
+
+- `lsp.enabled`: 启用/禁用原生 LSP 客户端（默认为 `false`）
+- `lsp.allowed`: 允许的 LSP 服务器名称白名单
+- `lsp.excluded`: 排除的 LSP 服务器名称黑名单
+
+在 settings.json 中的示例配置：
+
+```json
+{
+  "lsp": {
+    "enabled": true,
+    "allowed": ["typescript-language-server", "pylsp"],
+    "excluded": ["gopls"]
+  }
+}
+```
+
+也可以在 `settings.json` 中配置 `lsp.languageServers`，格式与 `.lsp.json` 一致。
+
+## 3. NativeLspService 调试功能
+
+`NativeLspService` 类包含几个调试功能：
+
+### 3.1 控制台日志
+
+服务向控制台输出状态消息：
+
+- `LSP 服务器 ${name} 启动成功` - 服务器成功启动
+- `LSP 服务器 ${name} 启动失败` - 服务器启动失败
+- `工作区不受信任，跳过 LSP 服务器发现` - 工作区不受信任，跳过发现
+
+### 3.2 错误处理
+
+服务具有全面的错误处理和详细的错误消息
+
+### 3.3 状态跟踪
+
+您可以通过 `getStatus()` 方法检查所有 LSP 服务器的状态
+
+## 4. 调试命令
+
+```bash
+# 启用调试运行
+qwen --debug --prompt "调试 LSP 功能"
+
+# 检查在您的项目中检测到哪些 LSP 服务器
+# 系统会自动检测语言和相应的 LSP 服务器
+```
+
+## 5. 手动 LSP 服务器配置
+
+您还可以在项目根目录使用 `.lsp.json` 文件手动配置 LSP 服务器。
+推荐使用新格式（以服务器名称为键），旧格式仍然兼容但会提示迁移：
+
+```json
+{
+  "languageServers": {
+    "pylsp": {
+      "command": "pylsp",
+      "args": [],
+      "languages": ["python"],
+      "transport": "stdio",
+      "settings": {},
+      "workspaceFolder": null,
+      "startupTimeout": 10000,
+      "shutdownTimeout": 3000,
+      "restartOnCrash": true,
+      "maxRestarts": 3,
+      "trustRequired": true
+    }
+  }
+}
+```
+
+旧格式示例：
+
+```json
+{
+  "python": {
+    "command": "pylsp",
+    "args": [],
+    "transport": "stdio",
+    "trustRequired": true
+  }
+}
+```
+
+## 6. LSP 问题排查
+
+### 6.1 检查 LSP 服务器是否已安装
+
+- 对于 TypeScript/JavaScript: `typescript-language-server`
+- 对于 Python: `pylsp`
+- 对于 Go: `gopls`
+
+### 6.2 验证工作区信任
+
+- LSP 服务器可能需要受信任的工作区才能启动
+- 检查 `security.folderTrust.enabled` 设置
+
+### 6.3 查看日志
+
+- 查找以 `LSP 服务器` 开头的控制台消息
+- 检查命令存在性和路径安全性问题
+
+## 7. LSP 服务启动流程
+
+LSP 服务的启动遵循以下流程：
+
+1. **发现和准备**: `discoverAndPrepare()` 方法检测工作区中的编程语言
+2. **创建服务器句柄**: 根据检测到的语言创建对应的服务器句柄
+3. **启动服务器**: `start()` 方法启动所有服务器句柄
+4. **状态管理**: 服务器状态在 `NOT_STARTED`, `IN_PROGRESS`, `READY`, `FAILED` 之间转换
+
+## 8. 调试技巧
+
+- 使用 `--debug` 标志查看详细的启动过程
+- 检查工作区是否受信任（影响 LSP 服务器启动）
+- 确认 LSP 服务器命令在系统 PATH 中可用
+- 使用 `getStatus()` 方法监控服务器运行状态

+# LSP 工具重构计划
+
+## 背景
+
+对比 Claude Code 的 LSP tool 定义和当前实现，发现以下关键差异：
+
+### Claude Code 的设计（目标）
+
+```json
+{
+  "name": "LSP",
+  "operations": [
+    "goToDefinition",
+    "findReferences",
+    "hover",
+    "documentSymbol",
+    "workspaceSymbol",
+    "goToImplementation",
+    "prepareCallHierarchy",
+    "incomingCalls",
+    "outgoingCalls"
+  ],
+  "required_params": ["operation", "filePath", "line", "character"]
+}
+```
+
+### 当前实现
+
+- **分散的 3 个工具**：`lsp_go_to_definition`, `lsp_find_references`, `lsp_workspace_symbol`
+- **支持 3 个操作**：goToDefinition, findReferences, workspaceSymbol
+- **缺少 6 个操作**：hover, documentSymbol, goToImplementation, prepareCallHierarchy, incomingCalls, outgoingCalls
+
+---
+
+## 重构目标
+
+1. **统一工具设计**：将 3 个分散的工具合并为 1 个统一的 `LSP` 工具
+2. **扩展操作支持**：添加缺失的 6 个 LSP 操作
+3. **简化参数设计**：统一使用 operation + filePath + line + character 方式
+4. **保持向后兼容**：旧工具名称继续支持
+
+---
+
+## 实施步骤
+
+### Step 1: 扩展类型定义
+
+**文件**: `packages/core/src/lsp/types.ts`
+
+新增类型：
+
+```typescript
+// Hover 结果
+interface LspHoverResult {
+  contents: string | { language: string; value: string }[];
+  range?: LspRange;
+}
+
+// Call Hierarchy 类型
+interface LspCallHierarchyItem {
+  name: string;
+  kind: number;
+  uri: string;
+  range: LspRange;
+  selectionRange: LspRange;
+  detail?: string;
+  data?: unknown;
+  serverName?: string;
+}
+
+interface LspCallHierarchyIncomingCall {
+  from: LspCallHierarchyItem;
+  fromRanges: LspRange[];
+}
+
+interface LspCallHierarchyOutgoingCall {
+  to: LspCallHierarchyItem;
+  fromRanges: LspRange[];
+}
+```
+
+扩展 LspClient 接口：
+
+```typescript
+interface LspClient {
+  // 现有方法
+  workspaceSymbols(query, limit): Promise<LspSymbolInformation[]>;
+  definitions(location, serverName, limit): Promise<LspDefinition[]>;
+  references(
+    location,
+    serverName,
+    includeDeclaration,
+    limit,
+  ): Promise<LspReference[]>;
+
+  // 新增方法
+  hover(location, serverName): Promise<LspHoverResult | null>;
+  documentSymbols(uri, serverName, limit): Promise<LspSymbolInformation[]>;
+  implementations(location, serverName, limit): Promise<LspDefinition[]>;
+  prepareCallHierarchy(location, serverName): Promise<LspCallHierarchyItem[]>;
+  incomingCalls(
+    item,
+    serverName,
+    limit,
+  ): Promise<LspCallHierarchyIncomingCall[]>;
+  outgoingCalls(
+    item,
+    serverName,
+    limit,
+  ): Promise<LspCallHierarchyOutgoingCall[]>;
+}
+```
+
+### Step 2: 创建统一 LSP 工具
+
+**新文件**: `packages/core/src/tools/lsp.ts`
+
+参数设计（采用灵活的操作特定验证）：
+
+```typescript
+interface LspToolParams {
+  operation: LspOperation; // 必填
+  filePath?: string; // 位置类操作必填
+  line?: number; // 精确位置操作必填 (1-based)
+  character?: number; // 可选 (1-based)
+  query?: string; // workspaceSymbol 必填
+  callHierarchyItem?: object; // incomingCalls/outgoingCalls 必填
+  serverName?: string; // 可选
+  limit?: number; // 可选
+  includeDeclaration?: boolean; // findReferences 可选
+}
+
+type LspOperation =
+  | 'goToDefinition'
+  | 'findReferences'
+  | 'hover'
+  | 'documentSymbol'
+  | 'workspaceSymbol'
+  | 'goToImplementation'
+  | 'prepareCallHierarchy'
+  | 'incomingCalls'
+  | 'outgoingCalls';
+```
+
+各操作参数要求：
+| 操作 | filePath | line | character | query | callHierarchyItem |
+|------|----------|------|-----------|-------|-------------------|
+| goToDefinition | 必填 | 必填 | 可选 | - | - |
+| findReferences | 必填 | 必填 | 可选 | - | - |
+| hover | 必填 | 必填 | 可选 | - | - |
+| documentSymbol | 必填 | - | - | - | - |
+| workspaceSymbol | - | - | - | 必填 | - |
+| goToImplementation | 必填 | 必填 | 可选 | - | - |
+| prepareCallHierarchy | 必填 | 必填 | 可选 | - | - |
+| incomingCalls | - | - | - | - | 必填 |
+| outgoingCalls | - | - | - | - | 必填 |
+
+### Step 3: 扩展 NativeLspService
+
+**文件**: `packages/cli/src/services/lsp/NativeLspService.ts`
+
+新增 6 个方法：
+
+1. `hover()` - 调用 `textDocument/hover`
+2. `documentSymbols()` - 调用 `textDocument/documentSymbol`
+3. `implementations()` - 调用 `textDocument/implementation`
+4. `prepareCallHierarchy()` - 调用 `textDocument/prepareCallHierarchy`
+5. `incomingCalls()` - 调用 `callHierarchy/incomingCalls`
+6. `outgoingCalls()` - 调用 `callHierarchy/outgoingCalls`
+
+### Step 4: 更新工具名称映射
+
+**文件**: `packages/core/src/tools/tool-names.ts`
+
+```typescript
+export const ToolNames = {
+  LSP: 'lsp', // 新增
+  // 保留旧名称（标记 deprecated）
+  LSP_WORKSPACE_SYMBOL: 'lsp_workspace_symbol',
+  LSP_GO_TO_DEFINITION: 'lsp_go_to_definition',
+  LSP_FIND_REFERENCES: 'lsp_find_references',
+} as const;
+
+export const ToolNamesMigration = {
+  lsp_go_to_definition: ToolNames.LSP,
+  lsp_find_references: ToolNames.LSP,
+  lsp_workspace_symbol: ToolNames.LSP,
+} as const;
+```
+
+### Step 5: 更新 Config 工具注册
+
+**文件**: `packages/core/src/config/config.ts`
+
+- 注册新的统一 `LspTool`
+- 保留旧工具注册（向后兼容）
+- 可通过配置选项禁用旧工具
+
+### Step 6: 向后兼容处理
+
+**文件**: 现有 3 个 LSP 工具文件
+
+- 添加 `@deprecated` 标记
+- 添加 deprecation warning 日志
+- 可选：内部转发到新工具实现
+
+---
+
+## 关键文件列表
+
+| 文件路径                                            | 操作                        |
+| --------------------------------------------------- | --------------------------- |
+| `packages/core/src/lsp/types.ts`                    | 修改 - 扩展类型定义         |
+| `packages/core/src/tools/lsp.ts`                    | 新建 - 统一 LSP 工具        |
+| `packages/core/src/tools/tool-names.ts`             | 修改 - 添加工具名称         |
+| `packages/cli/src/services/lsp/NativeLspService.ts` | 修改 - 添加 6 个新方法      |
+| `packages/core/src/config/config.ts`                | 修改 - 注册新工具           |
+| `packages/core/src/tools/lsp-*.ts` (3个)            | 修改 - 添加 deprecated 标记 |
+
+---
+
+## 验证方式
+
+1. **单元测试**：
+   - 新 `LspTool` 参数验证测试
+   - 各操作执行逻辑测试
+   - 向后兼容测试
+
+2. **集成测试**：
+   - TypeScript Language Server 测试所有 9 个操作
+   - Python LSP 测试
+   - 多服务器场景测试
+
+3. **手动验证**：
+   - 在 VS Code 中测试各操作
+   - 验证旧工具名称仍可使用
+   - 验证 deprecation warning 输出
+
+---
+
+## 风险与缓解
+
+| 风险                        | 缓解措施                               |
+| --------------------------- | -------------------------------------- |
+| 部分 LSP 服务器不支持新操作 | 独立 try-catch，返回清晰错误消息       |
+| Call Hierarchy 两步流程复杂 | 文档说明使用方式，提供示例             |
+| 向后兼容增加维护成本        | 设置明确弃用时间线，配置选项控制旧工具 |
+
+---
+
+## 后续优化建议
+
+1. 考虑是否需要支持更多 LSP 操作（如 `textDocument/rename`, `textDocument/formatting`）
+2. 考虑添加 LSP 服务器能力查询，动态返回支持的操作列表
+3. 考虑优化 TypeScript Server warm-up 逻辑，减少首次调用延迟
