services/oauth/） + +两者各有优劣。按技术划分的优势是关注点分离明确，劣势是跨领域修改需要改多个项目。考虑到 CLI 工具的特性，建议在现有技术分层基础上，通过命名空间和目录结构体现领域边界： + +```csharp +// FreeCode.Tools 内部按领域组织目录 +FreeCode.Tools/ +├── FileSystem/ (Read, Write, Edit, Glob) +├── Shell/ (Bash, PowerShell) +├── Search/ (Grep, ToolSearch) +├── Agent/ (AgentTool, SendMessageTool) +├── Web/ (WebFetch, WebSearch, WebBrowser) +├── Mcp/ (MCPTool, McpAuthTool) +├── PlanMode/ (EnterPlanMode, ExitPlanMode) +├── Tasks/ (TaskCreate, TaskList, ...) +└── Cron/ (CronCreate, CronDelete, CronList) +``` + +### 2.4 数据流 + +``` +用户输入 + → Program.Main() / QuickPathHandler + → IAppRunner.RunAsync() + → IQueryEngine.SubmitMessageAsync(content) + → IPromptBuilder.BuildAsync() // 6 段式 System Prompt + → IToolRegistry.GetToolsAsync() // 工具描述 + →

分发） + → AppendMessage() // 追加消息到历史 + → PostQueryProcessing() // 记忆提取 + → TerminalUI 渲染输出 +``` + +--- + +## 三、关键设计问题详解 + +### 问题 3.1 [Critical] ToolRegistry 巨型 switch 分发 + +**位置**: `src/FreeCode.Tools/ToolRegistry.cs:162-213` + +**问题描述**: +`ExecuteToolAsync` 方法包含一个 48 个 case 的 switch 表达式。每添加一个新工具需要同时修改三处：`GetBaseTools()` 注册列表（第 64-110 行）、switch 表达式（第 162-213 行）、Input/Output DTO 类。这严重违反 Open-Closed 原则。 + +**根因**: `ToolBase` 缺少统一的 `ExecuteAsync(JsonElement, ToolExecutionContext, CancellationToken)` 方法，导致 ToolRegistry 必须知道每个工具的具体类型才能调用泛型 `ExecuteAsync`。 + +**建议方案**: 责任链 + 统一执行入口 + +```csharp +// 方案一：ToolBase 添加通用执行方法（最小改动） +public abstract class ToolBase : ITool +{ + public virtual Task<(string Output, bool IsAllowed, bool ShouldContinue)> ExecuteFromJsonAsync( + JsonElement input, ToolExecutionContext context, CancellationToken ct) + { + // 默认实现：子类可以 override 或保持自动反序列化 + throw new NotImplementedException($"Tool '{Name}' must implement ExecuteFromJsonAsync"); + } +} + +// ToolRegistry 简化为： +public async Task<(string, bool, bool)> ExecuteToolAsync(...) +{ + // ... + if (tool is ToolBase toolBase) + return await toolBase.ExecuteFromJsonAsync(input, executionContext, ct); + if (tool is McpToolWrapper mcpTool) + return await ExecuteMcpToolAsync(mcpTool, input, ct); + throw new NotSupportedException($"No executor for tool: {tool.Name}"); +} +``` + +```csharp +// 方案二：责任链模式（更灵活，适合插件扩展） +public interface IToolExecutor +{ + bool CanExecute(ITool tool); + Task<(string Output, bool IsAllowed, bool ShouldContinue)> ExecuteAsync( + ITool tool, JsonElement input, ToolExecutionContext context, CancellationToken ct); +} + +public class ToolExecutorPipeline +{ + private readonly IToolExecutor[] _executors; + + public async Task<(string, bool, bool)> ExecuteAsync(ITool tool, JsonElement input, ...) + { + foreach (var executor in _executors) + { + if (executor.CanExecute(tool)) + return await executor.ExecuteAsync(tool, input, context, ct); + } + throw new NotSupportedException($"No executor for tool: {tool.Name}"); + } +} +``` + +--- + +### 问题 3.2 [Critical] IAppStateStore 弱类型 `object` 接口 + +**位置**: `src/FreeCode.Core/Interfaces/IAppStateStore.cs` (全文 11 行) + +**问题描述**: +核心状态接口使用 `object` 作为状态类型，迫使所有消费者进行强制类型转换。在 C# 的强类型系统中，这是不可接受的。 + +**连锁影响**: +| 消费者 | 位置 | 问题 | +|--------|------|------| +| AppStateStore | `AppStateStore.cs:33` | `as AppState ?? throw new InvalidCastException()` | +| ToolRegistry | `ToolRegistry.cs:288-295` | `GetProperty("PermissionMode")` 反射 | +| 所有消费者 | 各处 | `(AppState)store.GetState()` 强转 | +| Update 重载 | `AppStateStore.cs:91-95` | `Func` 包装为 `Func` | + +**建议方案**: 直接强类型化（推荐，改动最小） + +```csharp +// 直接暴露 AppState +public interface IAppStateStore +{ + AppState GetState(); // 强类型返回 + void Update(Func updater); // 强类型更新 + IDisposable Subscribe(Action listener); // 强类型通知 + event EventHandler? StateChanged; +} +``` + +**消除反射**: `ToolRegistry.ResolvePermissionMode` 从反射改为直接调用： + +```csharp +// 改前（反射） +private static PermissionMode ResolvePermissionMode(object appState) + => appState.GetType().GetProperty("PermissionMode")?.GetValue(appState) is PermissionMode pm + ? pm : PermissionMode.Default; + +// 改后（直接访问） +private static PermissionMode ResolvePermissionMode(AppState appState) + => appState.PermissionMode; +``` + +--- + +### 问题 3.3 [Critical] QueryEngine 神类 + Func 委托注入 + +**位置**: `src/FreeCode.Engine/QueryEngine.cs` (全文 423 行) + +**问题描述**: +1. 构造函数接收 **9 个参数**（第 12-20 行），其中 `toolExecutor` 是一个复杂的 `Func<...>` 委托 +2. 单一类承担 6+ 职责：流式响应、工具执行、消息管理、JSON 序列化、Token 估算、CancellationToken 管理 + +```csharp +public sealed class QueryEngine( + IApiProviderRouter apiProviderRouter, + IToolRegistry toolRegistry, // 为什么既注入 IToolRegistry 又注入 toolExecutor？ + IPermissionEngine permissionEngine, // 同样的冗余 + IPromptBuilder promptBuilder, + ISessionMemoryService sessionMemoryService, + IFeatureFlagService featureFlagService, + Func>? toolExecutor, // ← 反模式 + ILogger logger) : IQueryEngine +``` + +**建议拆分方案**: + +```csharp +// 1. IToolExecutor — 从 IToolRegistry 中提取工具执行职责 +public interface IToolExecutor +{ + Task<(string Output, bool IsAllowed, bool ShouldContinue)> ExecuteAsync( + string toolName, JsonElement input, ToolPermissionContext? context, CancellationToken ct); +} + +// 2. IMessageStore — 消息管理职责 +public interface IMessageStore +{ + void Append(Message message); + IReadOnlyList GetAll(); + TokenUsage EstimateUsage(); +} + +// 3. 重构后的 QueryEngine +public sealed class QueryEngine( + IApiProviderRouter apiProviderRouter, + IToolExecutor toolExecutor, // 替代 Func + IToolRegistry + IPromptBuilder promptBuilder, + IMessageStore messageStore, // 替代内部 _messages + ISessionMemoryService sessionMemoryService, + IFeatureFlagService featureFlagService, + ILogger logger) : IQueryEngine +``` + +--- + +### 问题 3.4 [High] AppState 巨型 Record — 单体状态 + +**位置**: `src/FreeCode.State/AppState.cs` (49 个属性) + +**问题描述**: +单个 `AppState` record 包含 49 个属性，涵盖配置、权限、任务、MCP、插件、远程、UI、Agent 等所有领域。任何属性变更都触发 `with {}` 重建，所有订阅者都收到通知。 + +**建议方案**: 分片状态管理 + +```csharp +// 按领域拆分状态切片 +public sealed record AppState +{ + public ConversationState Conversation { get; init; } = new(); + public McpState Mcp { get; init; } = McpState.Empty; + public TaskState Tasks { get; init; } = new(); + public UiState Ui { get; init; } = new(); + public PluginState Plugins { get; init; } = PluginState.Empty; +} + +// 支持选择性订阅 +public interface IStateSlice +{ + T Value { get; } + IObservable Observe(); + void Update(Func updater); +} + +// 组合管理器 +public class AppStateManager +{ + public IStateSlice Conversation { get; } + public IStateSlice Mcp { get; } + public IStateSlice Tasks { get; } + public IStateSlice Ui { get; } +} +``` + +--- + +### 问题 3.5 [High] PermissionEngine 从 IServiceProvider 获取工具 + +**位置**: `src/FreeCode.Services/PermissionEngine.cs:13` + +```csharp +var tool = context.Services.GetService(typeof(ITool)) as ITool; +var isReadOnly = tool?.IsReadOnly(input) ??

`src/FreeCode.Tools/ToolRegistry.cs:162-213` + +**问题描述**: +`ExecuteToolAsync` 方法包含一个 48 个 case 的 switch 表达式，每添加一个新工具需要同时修改三处：注册列表（GetBaseTools）、switch 表达式、Input/Output DTO 类。这是典型的 Open-Closed 原则违反。 + +```csharp +// 当前实现 — 每增加一个工具就要改这里 +return tool.Name switch +{ + "Agent" => await ExecuteAsync(...), + "Bash" => await ExecuteAsync(...), + "Read" => await ExecuteAsync(...), + // ... 48 个 case + _ => ($"Unsupported tool execution for {tool.Name}", true, false) +}; +``` + +**根因**: `ToolBase` 缺少统一的 `ExecuteAsync(JsonElement, ToolExecutionContext, CancellationToken)` 方法，导致 ToolRegistry 必须知道每个工具的具体类型才能调用泛型 `ExecuteAsync`。 + +**建议方案**: 在 `ToolBase` 中添加基于 `JsonElement` 的统一执行入口： + +```csharp +// 建议方案：ToolBase 添加通用执行方法 +public abstract class ToolBase : ITool +{ + // 新增：统一的 JSON 执行入口 + public abstract Task<(string Output, bool IsAllowed, bool ShouldContinue)> ExecuteFromJsonAsync( + JsonElement input, ToolExecutionContext context, CancellationToken ct); + + // 子类实现 + public override Task<(string, bool, bool)> ExecuteFromJsonAsync( + JsonElement input, ToolExecutionContext context, CancellationToken ct) + { + var typedInput = JsonSerializer.Deserialize(input.GetRawText())!; + // ... execute logic + } +} + +// ToolRegistry 简化为： +if (tool is ToolBase toolBase) +{ + return await toolBase.ExecuteFromJsonAsync(input, executionContext, ct); +} +``` + +--- + +### 问题 3.2 [Critical] IAppStateStore 弱类型 `object` 接口 + +**位置**: `src/FreeCode.Core/Interfaces/IAppStateStore.cs` (全部 11 行) + +**问题描述**: +核心状态接口使用 `object` 作为状态类型，迫使所有消费者进行强制类型转换。这完全违背了 C# 强类型系统的设计理念。 + +```csharp +// 当前 — 弱类型 +public interface IAppStateStore +{ + object GetState(); // 返回 object + void Update(Func updater); // Func + IDisposable Subscribe(Action listener); // Action + event EventHandler? StateChanged; +} +``` + +**连锁影响**: +- `AppStateStore.cs:33` — 需要 `as AppState ?? throw new InvalidCastException()` +- `ToolRegistry.cs:288-295` — `ResolvePermissionMode` 使用反射 `GetProperty("PermissionMode")` +- 所有状态消费者都需要 `(AppState)store.GetState()` 强转 + +**建议方案**: 使用泛型接口或直接暴露 AppState： + +```csharp +// 方案A：泛型接口 +public interface IStateStore where TState : notnull +{ + TState GetState(); + void Update(Func updater); + IDisposable Subscribe(Action listener); + event EventHandler>?
