+# 如何为 AI Provider 编写中间件
+
+本文档旨在指导开发者如何为我们的 AI Provider 框架创建和集成自定义中间件。中间件提供了一种强大而灵活的方式来增强、修改或观察 Provider 方法的调用过程，例如日志记录、缓存、请求/响应转换、错误处理等。
+
+## 架构概览
+
+我们的中间件架构借鉴了 Redux 的三段式设计，并结合了 JavaScript Proxy 来动态地将中间件应用于 Provider 的方法。
+
+- **Proxy**: 拦截对 Provider 方法的调用，并将调用引导至中间件链。
+- **中间件链**: 一系列按顺序执行的中间件函数。每个中间件都可以处理请求/响应，然后将控制权传递给链中的下一个中间件，或者在某些情况下提前终止链。
+- **上下文 (Context)**: 一个在中间件之间传递的对象，携带了关于当前调用的信息（如方法名、原始参数、Provider 实例、以及中间件自定义的数据）。
+
+## 中间件的类型
+
+目前主要支持两种类型的中间件，它们共享相似的结构但针对不同的场景：
+
+1.  **`CompletionsMiddleware`**: 专门为 `completions` 方法设计。这是最常用的中间件类型，因为它允许对 AI 模型的核心聊天/文本生成功能进行精细控制。
+2.  **`ProviderMethodMiddleware`**: 通用中间件，可以应用于 Provider 上的任何其他方法（例如，`translate`, `summarize` 等，如果这些方法也通过中间件系统包装）。
+
+## 编写一个 `CompletionsMiddleware`
+
+`CompletionsMiddleware` 的基本签名（TypeScript 类型）如下：
+
+```typescript
+import { AiProviderMiddlewareCompletionsContext, CompletionsParams, MiddlewareAPI } from './AiProviderMiddlewareTypes' // 假设类型定义文件路径
+
+export type CompletionsMiddleware = (
+  api: MiddlewareAPI<AiProviderMiddlewareCompletionsContext, [CompletionsParams]>
+) => (
+  next: (context: AiProviderMiddlewareCompletionsContext, params: CompletionsParams) => Promise<any> // next 返回 Promise<any> 代表原始SDK响应或下游中间件的结果
+) => (context: AiProviderMiddlewareCompletionsContext, params: CompletionsParams) => Promise<void> // 最内层函数通常返回 Promise<void>，因为结果通过 onChunk 或 context 副作用传递
+```
+
+让我们分解这个三段式结构：
+
+1.  **第一层函数 `(api) => { ... }`**:
+
+    - 接收一个 `api` 对象。
+    - `api` 对象提供了以下方法：
+      - `api.getContext()`: 获取当前调用的上下文对象 (`AiProviderMiddlewareCompletionsContext`)。
+      - `api.getOriginalArgs()`: 获取传递给 `completions` 方法的原始参数数组 (即 `[CompletionsParams]`)。
+      - `api.getProviderId()`: 获取当前 Provider 的 ID。
+      - `api.getProviderInstance()`: 获取原始的 Provider 实例。
+    - 此函数通常用于进行一次性的设置或获取所需的服务/配置。它返回第二层函数。
+
+2.  **第二层函数 `(next) => { ... }`**:
+
+    - 接收一个 `next` 函数。
+    - `next` 函数代表了中间件链中的下一个环节。调用 `next(context, params)` 会将控制权传递给下一个中间件，或者如果当前中间件是链中的最后一个，则会调用核心的 Provider 方法逻辑 (例如，实际的 SDK 调用)。
+    - `next` 函数接收当前的 `context` 和 `params` (这些可能已被上游中间件修改)。
+    - **重要的是**：`next` 的返回类型通常是 `Promise<any>`。对于 `completions` 方法，如果 `next` 调用了实际的 SDK，它将返回原始的 SDK 响应（例如，OpenAI 的流对象或 JSON 对象）。你需要处理这个响应。
+    - 此函数返回第三层（也是最核心的）函数。
+
+3.  **第三层函数 `(context, params) => { ... }`**:
+    - 这是执行中间件主要逻辑的地方。
+    - 它接收当前的 `context` (`AiProviderMiddlewareCompletionsContext`) 和 `params` (`CompletionsParams`)。
+    - 在此函数中，你可以：
+      - **在调用 `next` 之前**:
+        - 读取或修改 `params`。例如，添加默认参数、转换消息格式。
+        - 读取或修改 `context`。例如，设置一个时间戳用于后续计算延迟。
+        - 执行某些检查，如果不满足条件，可以不调用 `next` 而直接返回或抛出错误（例如，参数校验失败）。
+      - **调用 `await next(context, params)`**:
+        - 这是将控制权传递给下游的关键步骤。
+        - `next` 的返回值是原始的 SDK 响应或下游中间件的结果，你需要根据情况处理它（例如，如果是流，则开始消费流）。
+      - **在调用 `next` 之后**:
+        - 处理 `next` 的返回结果。例如，如果 `next` 返回了一个流，你可以在这里开始迭代处理这个流，并通过 `context.onChunk` 发送数据块。
+        - 基于 `context` 的变化或 `next` 的结果执行进一步操作。例如，计算总耗时、记录日志。
+        - 修改最终结果（尽管对于 `completions`，结果通常通过 `onChunk` 副作用发出）。
+
+### 示例：一个简单的日志中间件
+
+```typescript
+import {
+  AiProviderMiddlewareCompletionsContext,
+  CompletionsParams,
+  MiddlewareAPI,
+  OnChunkFunction // 假设 OnChunkFunction 类型被导出
+} from './AiProviderMiddlewareTypes' // 调整路径
+import { ChunkType } from '@renderer/types' // 调整路径
+
+export const createSimpleLoggingMiddleware = (): CompletionsMiddleware => {
+  return (api: MiddlewareAPI<AiProviderMiddlewareCompletionsContext, [CompletionsParams]>) => {
+    // console.log(`[LoggingMiddleware] Initialized for provider: ${api.getProviderId()}`);
+
+    return (next: (context: AiProviderMiddlewareCompletionsContext, params: CompletionsParams) => Promise<any>) => {
+      return async (context: AiProviderMiddlewareCompletionsContext, params: CompletionsParams): Promise<void> => {
+        const startTime = Date.now()
+        // 从 context 中获取 onChunk (它最初来自 params.onChunk)
+        const onChunk = context.onChunk
+
+        console.log(
+          `[LoggingMiddleware] Request for ${context.methodName} with params:`,
+          params.messages?.[params.messages.length - 1]?.content
+        )
+
+        try {
+          // 调用下一个中间件或核心逻辑
+          // `rawSdkResponse` 是来自下游的原始响应 (例如 OpenAIStream 或 ChatCompletion 对象)
+          const rawSdkResponse = await next(context, params)
+
+          // 此处简单示例不处理 rawSdkResponse，假设下游中间件 (如 StreamingResponseHandler)
+          // 会处理它并通过 onChunk 发送数据。
+          // 如果这个日志中间件在 StreamingResponseHandler 之后，那么流已经被处理。
+          // 如果在之前，那么它需要自己处理 rawSdkResponse 或确保下游会处理。
+
+          const duration = Date.now() - startTime
+          console.log(`[LoggingMiddleware] Request for ${context.methodName} completed in ${duration}ms.`)
+
+          // 假设下游已经通过 onChunk 发送了所有数据。
+          // 如果这个中间件是链的末端，并且需要确保 BLOCK_COMPLETE 被发送，
+          // 它可能需要更复杂的逻辑来跟踪何时所有数据都已发送。
+        } catch (error) {
+          const duration = Date.now() - startTime
+          console.error(`[LoggingMiddleware] Request for ${context.methodName} failed after ${duration}ms:`, error)
+
+          // 如果 onChunk 可用，可以尝试发送一个错误块
+          if (onChunk) {
+            onChunk({
+              type: ChunkType.ERROR,
+              error: { message: (error as Error).message, name: (error as Error).name, stack: (error as Error).stack }
+            })
+            // 考虑是否还需要发送 BLOCK_COMPLETE 来结束流
+            onChunk({ type: ChunkType.BLOCK_COMPLETE, response: {} })
+          }
+          throw error // 重新抛出错误，以便上层或全局错误处理器可以捕获
+        }
+      }
+    }
+  }
+}
+```
+
+### `AiProviderMiddlewareCompletionsContext` 的重要性
+
+`AiProviderMiddlewareCompletionsContext` 是在中间件之间传递状态和数据的核心。它通常包含：
+
+- `methodName`: 当前调用的方法名 (总是 `'completions'`)。
+- `originalArgs`: 传递给 `completions` 的原始参数数组。
+- `providerId`: Provider 的 ID。
+- `_providerInstance`: Provider 实例。
+- `onChunk`: 从原始 `CompletionsParams` 传入的回调函数，用于流式发送数据块。**所有中间件都应该通过 `context.onChunk` 来发送数据。**
+- `messages`, `model`, `assistant`, `mcpTools`: 从原始 `CompletionsParams` 中提取的常用字段，方便访问。
+- **自定义字段**: 中间件可以向上下文中添加自定义字段，以供后续中间件使用。例如，一个缓存中间件可能会添加 `context.cacheHit = true`。
+
+**关键**: 当你在中间件中修改 `params` 或 `context` 时，这些修改会向下游中间件传播（如果它们在 `next` 调用之前修改）。
+
+### 中间件的顺序
+
+中间件的执行顺序非常重要。它们在 `AiProviderMiddlewareConfig` 的数组中定义的顺序就是它们的执行顺序。
+
+- 请求首先通过第一个中间件，然后是第二个，依此类推。
+- 响应（或 `next` 的调用结果）则以相反的顺序"冒泡"回来。
+
+例如，如果链是 `[AuthMiddleware, CacheMiddleware, LoggingMiddleware]`：
+
+1.  `AuthMiddleware` 先执行其 "调用 `next` 之前" 的逻辑。
+2.  然后 `CacheMiddleware` 执行其 "调用 `next` 之前" 的逻辑。
+3.  然后 `LoggingMiddleware` 执行其 "调用 `next` 之前" 的逻辑。
+4.  核心SDK调用（或链的末端）。
+5.  `LoggingMiddleware` 先接收到结果，执行其 "调用 `next` 之后" 的逻辑。
+6.  然后 `CacheMiddleware` 接收到结果（可能已被 LoggingMiddleware 修改的上下文），执行其 "调用 `next` 之后" 的逻辑（例如，存储结果）。
+7.  最后 `AuthMiddleware` 接收到结果，执行其 "调用 `next` 之后" 的逻辑。
+
+### 注册中间件
+
+中间件在 `src/renderer/src/providers/middleware/register.ts` (或其他类似的配置文件) 中进行注册。
+
+```typescript
+// register.ts
+import { AiProviderMiddlewareConfig } from './AiProviderMiddlewareTypes'
+import { createSimpleLoggingMiddleware } from './common/SimpleLoggingMiddleware' // 假设你创建了这个文件
+import { createCompletionsLoggingMiddleware } from './common/CompletionsLoggingMiddleware' // 已有的
+
+const middlewareConfig: AiProviderMiddlewareConfig = {
+  completions: [
+    createSimpleLoggingMiddleware(), // 你新加的中间件
+    createCompletionsLoggingMiddleware() // 已有的日志中间件
+    // ... 其他 completions 中间件
+  ],
+  methods: {
+    // translate: [createGenericLoggingMiddleware()],
+    // ... 其他方法的中间件
+  }
+}
+
+export default middlewareConfig
+```
+
+### 最佳实践
+
+1.  **单一职责**: 每个中间件应专注于一个特定的功能（例如，日志、缓存、转换特定数据）。
+2.  **无副作用 (尽可能)**: 除了通过 `context` 或 `onChunk` 明确的副作用外，尽量避免修改全局状态或产生其他隐蔽的副作用。
+3.  **错误处理**:
+    - 在中间件内部使用 `try...catch` 来处理可能发生的错误。
+    - 决定是自行处理错误（例如，通过 `onChunk` 发送错误块）还是将错误重新抛出给上游。
+    - 如果重新抛出，确保错误对象包含足够的信息。
+4.  **性能考虑**: 中间件会增加请求处理的开销。避免在中间件中执行非常耗时的同步操作。对于IO密集型操作，确保它们是异步的。
+5.  **可配置性**: 使中间件的行为可通过参数或配置进行调整。例如，日志中间件可以接受一个日志级别参数。
+6.  **上下文管理**:
+    - 谨慎地向 `context` 添加数据。避免污染 `context` 或添加过大的对象。
+    - 明确你添加到 `context` 的字段的用途和生命周期。
+7.  **`next` 的调用**:
+    - 除非你有充分的理由提前终止请求（例如，缓存命中、授权失败），否则**总是确保调用 `await next(context, params)`**。否则，下游的中间件和核心逻辑将不会执行。
+    - 理解 `next` 的返回值并正确处理它，特别是当它是一个流时。你需要负责消费这个流或将其传递给另一个能够消费它的组件/中间件。
+8.  **命名清晰**: 给你的中间件和它们创建的函数起描述性的名字。
+9.  **文档和注释**: 对复杂的中间件逻辑添加注释，解释其工作原理和目的。
+
+### 调试技巧
+
+- 在中间件的关键点使用 `console.log` 或调试器来检查 `params`、`context` 的状态以及 `next` 的返回值。
+- 暂时简化中间件链，只保留你正在调试的中间件和最简单的核心逻辑，以隔离问题。
+- 编写单元测试来独立验证每个中间件的行为。
+
+通过遵循这些指南，你应该能够有效地为我们的系统创建强大且可维护的中间件。如果你有任何疑问或需要进一步的帮助，请咨询团队。

+# Cherry Studio AI Provider 技术架构文档 (新方案)
+
+## 1. 核心设计理念与目标
+
+本架构旨在重构 Cherry Studio 的 AI Provider（现称为 `aiCore`）层，以实现以下目标：
+
+- **职责清晰**：明确划分各组件的职责，降低耦合度。
+- **高度复用**：最大化业务逻辑和通用处理逻辑的复用，减少重复代码。
+- **易于扩展**：方便快捷地接入新的 AI Provider (LLM供应商) 和添加新的 AI 功能 (如翻译、摘要、图像生成等)。
+- **易于维护**：简化单个组件的复杂性，提高代码的可读性和可维护性。
+- **标准化**：统一内部数据流和接口，简化不同 Provider 之间的差异处理。
+
+核心思路是将纯粹的 **SDK 适配层 (`XxxApiClient`)**、**通用逻辑处理与智能解析层 (中间件)** 以及 **统一业务功能入口层 (`AiCoreService`)** 清晰地分离开来。
+
+## 2. 核心组件详解
+
+### 2.1. `aiCore` (原 `AiProvider` 文件夹)
+
+这是整个 AI 功能的核心模块。
+
+#### 2.1.1. `XxxApiClient` (例如 `aiCore/clients/openai/OpenAIApiClient.ts`)
+
+- **职责**：作为特定 AI Provider SDK 的纯粹适配层。
+  - **参数适配**：将应用内部统一的 `CoreRequest` 对象 (见下文) 转换为特定 SDK 所需的请求参数格式。
+  - **基础响应转换**：将 SDK 返回的原始数据块 (`RawSdkChunk`，例如 `OpenAI.Chat.Completions.ChatCompletionChunk`) 转换为一组最基础、最直接的应用层 `Chunk` 对象 (定义于 `src/renderer/src/types/chunk.ts`)。
+    - 例如：SDK 的 `delta.content` -> `TextDeltaChunk`；SDK 的 `delta.reasoning_content` -> `ThinkingDeltaChunk`；SDK 的 `delta.tool_calls` -> `RawToolCallChunk` (包含原始工具调用数据)。
+    - **关键**：`XxxApiClient` **不处理**耦合在文本内容中的复杂结构，如 `<think>` 或 `<tool_use>` 标签。
+- **特点**：极度轻量化，代码量少，易于实现和维护新的 Provider 适配。
+
+#### 2.1.2. `ApiClient.ts` (或 `BaseApiClient.ts` 的核心接口)
+
+- 定义了所有 `XxxApiClient` 必须实现的接口，如：
+  - `getSdkInstance(): Promise<TSdkInstance> | TSdkInstance`
+  - `getRequestTransformer(): RequestTransformer<TSdkParams>`
+  - `getResponseChunkTransformer(): ResponseChunkTransformer<TRawChunk, TResponseContext>`
+  - 其他可选的、与特定 Provider 相关的辅助方法 (如工具调用转换)。
+
+#### 2.1.3. `ApiClientFactory.ts`
+
+- 根据 Provider 配置动态创建和返回相应的 `XxxApiClient` 实例。
+
+#### 2.1.4. `AiCoreService.ts` (`aiCore/index.ts`)
+
+- **职责**：作为所有 AI 相关业务功能的统一入口。
+  - 提供面向应用的高层接口，例如：
+    - `executeCompletions(params: CompletionsParams): Promise<AggregatedCompletionsResult>`
+    - `translateText(params: TranslateParams): Promise<AggregatedTranslateResult>`
+    - `summarizeText(params: SummarizeParams): Promise<AggregatedSummarizeResult>`
+    - 未来可能的 `generateImage(prompt: string): Promise<ImageResult>` 等。
+  - **返回 `Promise`**：每个服务方法返回一个 `Promise`，该 `Promise` 会在整个（可能是流式的）操作完成后，以包含所有聚合结果（如完整文本、工具调用详情、最终的`usage`/`metrics`等）的对象来 `resolve`。
+  - **支持流式回调**：服务方法的参数 (如 `CompletionsParams`) 依然包含 `onChunk` 回调，用于向调用方实时推送处理过程中的 `Chunk` 数据，实现流式UI更新。
+  - **封装特定任务的提示工程 (Prompt Engineering)**：
+    - 例如，`translateText` 方法内部会构建一个包含特定翻译指令的 `CoreRequest`。
+  - **编排和调用中间件链**：通过内部的 `MiddlewareBuilder` (参见 `middleware/BUILDER_USAGE.md`) 实例，根据调用的业务方法和参数，动态构建和组织合适的中间件序列，然后通过 `applyCompletionsMiddlewares` 等组合函数执行。
+  - 获取 `ApiClient` 实例并将其注入到中间件上游的 `Context` 中。
+  - **将 `Promise` 的 `resolve` 和 `reject` 函数传递给中间件链** (通过 `Context`)，以便 `FinalChunkConsumerAndNotifierMiddleware` 可以在操作完成或发生错误时结束该 `Promise`。
+- **优势**：
+  - 业务逻辑（如翻译、摘要的提示构建和流程控制）只需实现一次，即可支持所有通过 `ApiClient` 接入的底层 Provider。
+  - **支持外部编排**：调用方可以 `await` 服务方法以获取最终聚合结果，然后将此结果作为后续操作的输入，轻松实现多步骤工作流。
+  - **支持内部组合**：服务自身也可以通过 `await` 调用其他原子服务方法来构建更复杂的组合功能。
+
+#### 2.1.5. `coreRequestTypes.ts` (或 `types.ts`)
+
+- 定义核心的、Provider 无关的内部请求结构，例如：
+  - `CoreCompletionsRequest`: 包含标准化后的消息列表、模型配置、工具列表、最大Token数、是否流式输出等。
+  - `CoreTranslateRequest`, `CoreSummarizeRequest` 等 (如果与 `CoreCompletionsRequest` 结构差异较大，否则可复用并添加任务类型标记)。
+
+### 2.2. `middleware`
+
+中间件层负责处理请求和响应流中的通用逻辑和特定特性。其设计和使用遵循 `middleware/BUILDER_USAGE.md` 中定义的规范。
+
+**核心组件包括：**
+
+- **`MiddlewareBuilder`**: 一个通用的、提供流式API的类，用于动态构建中间件链。它支持从基础链开始，根据条件添加、插入、替换或移除中间件。
+- **`applyCompletionsMiddlewares`**: 负责接收 `MiddlewareBuilder` 构建的链并按顺序执行，专门用于 Completions 流程。
+- **`MiddlewareRegistry`**: 集中管理所有可用中间件的注册表，提供统一的中间件访问接口。
+- **各种独立的中间件模块** (存放于 `common/`, `core/`, `feat/` 子目录)。
+
+#### 2.2.1. `middlewareTypes.ts`
+
+- 定义中间件的核心类型，如 `AiProviderMiddlewareContext` (扩展后包含 `_apiClientInstance` 和 `_coreRequest`)、`MiddlewareAPI`、`CompletionsMiddleware` 等。
+
+#### 2.2.2. 核心中间件 (`middleware/core/`)
+
+- **`TransformCoreToSdkParamsMiddleware.ts`**: 调用 `ApiClient.getRequestTransformer()` 将 `CoreRequest` 转换为特定 SDK 的参数，并存入上下文。
+- **`RequestExecutionMiddleware.ts`**: 调用 `ApiClient.getSdkInstance()` 获取 SDK 实例，并使用转换后的参数执行实际的 API 调用，返回原始 SDK 流。
+- **`StreamAdapterMiddleware.ts`**: 将各种形态的原始 SDK 流 (如异步迭代器) 统一适配为 `ReadableStream<RawSdkChunk>`。
+  - **`RawSdkChunk`**：指特定AI提供商SDK在流式响应中返回的、未经应用层统一处理的原始数据块格式 (例如 OpenAI 的 `ChatCompletionChunk`，Gemini 的 `GenerateContentResponse` 中的部分等)。
+- **`RawSdkChunkToAppChunkMiddleware.ts`**: (新增) 消费 `ReadableStream<RawSdkChunk>`，在其内部对每个 `RawSdkChunk` 调用 `ApiClient.getResponseChunkTransformer()`，将其转换为一个或多个基础的应用层 `Chunk` 对象，并输出 `ReadableStream<Chunk>`。
+
+#### 2.2.3. 特性中间件 (`middleware/feat/`)
+
+这些中间件消费由 `ResponseTransformMiddleware` 输出的、相对标准化的 `Chunk` 流，并处理更复杂的逻辑。
+
+- **`ThinkingTagExtractionMiddleware.ts`**: 检查 `TextDeltaChunk`，解析其中可能包含的 `<think>...</think>` 文本内嵌标签，生成 `ThinkingDeltaChunk` 和 `ThinkingCompleteChunk`。
+- **`ToolUseExtractionMiddleware.ts`**: 检查 `TextDeltaChunk`，解析其中可能包含的 `<tool_use>...</tool_use>` 文本内嵌标签，生成工具调用相关的 Chunk。如果 `ApiClient` 输出了原生工具调用数据，此中间件也负责将其转换为标准格式。
+
+#### 2.2.4. 核心处理中间件 (`middleware/core/`)
+
+- **`TransformCoreToSdkParamsMiddleware.ts`**: 调用 `ApiClient.getRequestTransformer()` 将 `CoreRequest` 转换为特定 SDK 的参数，并存入上下文。
+- **`SdkCallMiddleware.ts`**: 调用 `ApiClient.getSdkInstance()` 获取 SDK 实例，并使用转换后的参数执行实际的 API 调用，返回原始 SDK 流。
+- **`StreamAdapterMiddleware.ts`**: 将各种形态的原始 SDK 流统一适配为标准流格式。
+- **`ResponseTransformMiddleware.ts`**: 将原始 SDK 响应转换为应用层标准 `Chunk` 对象。
+- **`TextChunkMiddleware.ts`**: 处理文本相关的 Chunk 流。
+- **`ThinkChunkMiddleware.ts`**: 处理思考相关的 Chunk 流。
+- **`McpToolChunkMiddleware.ts`**: 处理工具调用相关的 Chunk 流。
+- **`WebSearchMiddleware.ts`**: 处理 Web 搜索相关逻辑。
+
+#### 2.2.5. 通用中间件 (`middleware/common/`)
+
+- **`LoggingMiddleware.ts`**: 请求和响应日志。
+- **`AbortHandlerMiddleware.ts`**: 处理请求中止。
+- **`FinalChunkConsumerMiddleware.ts`**: 消费最终的 `Chunk` 流，通过 `context.onChunk` 回调通知应用层实时数据。
+  - **累积数据**：在流式处理过程中，累积关键数据，如文本片段、工具调用信息、`usage`/`metrics` 等。
+  - **结束 `Promise`**：当输入流结束时，使用累积的聚合结果来完成整个处理流程。
+  - 在流结束时，发送包含最终累加信息的完成信号。
+
+### 2.3. `types/chunk.ts`
+
+- 定义应用全局统一的 `Chunk` 类型及其所有变体。这包括基础类型 (如 `TextDeltaChunk`, `ThinkingDeltaChunk`)、SDK原生数据传递类型 (如 `RawToolCallChunk`, `RawFinishChunk` - 作为 `ApiClient` 转换的中间产物)，以及功能性类型 (如 `McpToolCallRequestChunk`, `WebSearchCompleteChunk`)。

+## 3. 核心执行流程 (以 `AiCoreService.executeCompletions` 为例)
+
+```markdown
+**应用层 (例如 UI 组件)**
+||
+\\/
+**`AiProvider.completions` (`aiCore/index.ts`)**
+(1. prepare ApiClient instance. 2. use `CompletionsMiddlewareBuilder.withDefaults()` to build middleware chain. 3. call `applyCompletionsMiddlewares`)
+||
+\\/
+**`applyCompletionsMiddlewares` (`middleware/composer.ts`)**

+||
+\\/
+**[ 预处理阶段中间件 ]**
+(例如: `FinalChunkConsumerMiddleware`, `TransformCoreToSdkParamsMiddleware`, `AbortHandlerMiddleware`)
+|| (Context 中准备好 SDK 请求参数)

+## 5. 迁移和实施建议
+
+- **小步快跑，逐步迭代**：优先完成核心流程的重构（例如 `completions`），再逐步迁移其他功能（`translate` 等）和其他 Provider。
+- **优先定义核心类型**：`CoreRequest`, `Chunk`, `ApiClient` 接口是整个架构的基石。
+- **为 `ApiClient` 瘦身**：将现有 `XxxProvider` 中的复杂逻辑剥离到新的中间件或 `AiCoreService` 中。
+- **强化中间件**：让中间件承担起更多解析和特性处理的责任。
+- **编写单元测试和集成测试**：确保每个组件和整体流程的正确性。
+
+此架构旨在提供一个更健壮、更灵活、更易于维护的 AI 功能核心，支撑 Cherry Studio 未来的发展。
+
+## 6. 迁移策略与实施建议
+
+本节内容提炼自早期的 `migrate.md` 文档，并根据最新的架构讨论进行了调整。
+
+**目标架构核心组件回顾：**
+
+与第 2 节描述的核心组件一致，主要包括 `XxxApiClient`, `AiCoreService`, 中间件链, `CoreRequest` 类型, 和标准化的 `Chunk` 类型。
+
+**迁移步骤：**
+
+**Phase 0: 准备工作和类型定义**
+
+1.  **定义核心数据结构 (TypeScript 类型)：**
+    - `CoreCompletionsRequest` (Type)：定义应用内部统一的对话请求结构。
+    - `Chunk` (Type - 检查并按需扩展现有 `src/renderer/src/types/chunk.ts`)：定义所有可能的通用Chunk类型。
+    - 为其他API（翻译、总结）定义类似的 `CoreXxxRequest` (Type)。
+2.  **定义 `ApiClient` 接口：** 明确 `getRequestTransformer`, `getResponseChunkTransformer`, `getSdkInstance` 等核心方法。
+3.  **调整 `AiProviderMiddlewareContext`：**
+    - 确保包含 `_apiClientInstance: ApiClient<any,any,any>`。
+    - 确保包含 `_coreRequest: CoreRequestType`。
+    - 考虑添加 `resolvePromise: (value: AggregatedResultType) => void` 和 `rejectPromise: (reason?: any) => void` 用于 `AiCoreService` 的 Promise 返回。
+
+**Phase 1: 实现第一个 `ApiClient` (以 `OpenAIApiClient` 为例)**
+
+1.  **创建 `OpenAIApiClient` 类：** 实现 `ApiClient` 接口。
+2.  **迁移SDK实例和配置。**
+3.  **实现 `getRequestTransformer()`：** 将 `CoreCompletionsRequest` 转换为 OpenAI SDK 参数。
+4.  **实现 `getResponseChunkTransformer()`：** 将 `OpenAI.Chat.Completions.ChatCompletionChunk` 转换为基础的 `

+# MiddlewareBuilder 使用指南
+
+`MiddlewareBuilder` 是一个用于动态构建和管理中间件链的工具，提供灵活的中间件组织和配置能力。
+
+## 主要特性
+
+### 1. 统一的中间件命名
+
+所有中间件都通过导出的 `MIDDLEWARE_NAME` 常量标识：
+
+```typescript
+// 中间件文件示例
+export const MIDDLEWARE_NAME = 'SdkCallMiddleware'
+export const SdkCallMiddleware: CompletionsMiddleware = ...
+```
+
+### 2. NamedMiddleware 接口
+
+中间件使用统一的 `NamedMiddleware` 接口格式：
+
+```typescript
+interface NamedMiddleware<TMiddleware = any> {
+  name: string
+  middleware: TMiddleware
+}
+```
+
+### 3. 中间件注册表
+
+通过 `MiddlewareRegistry` 集中管理所有可用中间件：
+
+```typescript
+import { MiddlewareRegistry } from './register'
+
+// 通过名称获取中间件
+const sdkCallMiddleware = MiddlewareRegistry['SdkCallMiddleware']
+```
+
+## 基本用法
+
+### 1. 使用默认中间件链
+
+```typescript
+import { CompletionsMiddlewareBuilder } from './builder'
+
+const builder = CompletionsMiddlewareBuilder.withDefaults()
+const middlewares = builder.build()
+```
+
+### 2. 自定义中间件链
+
+```typescript
+import { createCompletionsBuilder, MiddlewareRegistry } from './builder'
+
+const builder = createCompletionsBuilder([
+  MiddlewareRegistry['AbortHandlerMiddleware'],
+  MiddlewareRegistry['TextChunkMiddleware']
+])
+
+const middlewares = builder.build()
+```
+
+### 3. 动态调整中间件链
+
+```typescript
+const builder = CompletionsMiddlewareBuilder.withDefaults()
+
+// 根据条件添加、移除、替换中间件
+if (needsLogging) {
+  builder.prepend(MiddlewareRegistry['GenericLoggingMiddleware'])
+}
+
+if (disableTools) {
+  builder.remove('McpToolChunkMiddleware')
+}
+
+if (customThinking) {
+  builder.replace('ThinkingTagExtractionMiddleware', customThinkingMiddleware)
+}
+
+const middlewares = builder.build()
+```
+
+### 4. 链式操作
+
+```typescript
+const middlewares = CompletionsMiddlewareBuilder.withDefaults()
+  .add(MiddlewareRegistry['CustomMiddleware'])
+  .insertBefore('SdkCallMiddleware', MiddlewareRegistry['SecurityCheckMiddleware'])
+  .remove('WebSearchMiddleware')
+  .build()
+```
+
+## API 参考
+
+### CompletionsMiddlewareBuilder
+
+**静态方法：**
+
+- `static withDefaults()`: 创建带有默认中间件链的构建器
+
+**实例方法：**
+
+- `add(middleware: NamedMiddleware)`: 在链末尾添加中间件
+- `prepend(middleware: NamedMiddleware)`: 在链开头添加中间件
+- `insertAfter(targetName: string, middleware: NamedMiddleware)`: 在指定中间件后插入
+- `insertBefore(targetName: string, middleware: NamedMiddleware)`: 在指定中间件前插入
+- `replace(targetName: string, middleware: NamedMiddleware)`: 替换指定中间件
+- `remove(targetName: string)`: 移除指定中间件
+- `has(name: string)`: 检查是否包含指定中间件
+- `build()`: 构建最终的中间件数组
+- `getChain()`: 获取当前链（包含名称信息）
+- `clear()`: 清空中间件链
+- `execute(context, params, middlewareExecutor)`: 直接执行构建好的中间件链
+
+### 工厂函数
+
+- `createCompletionsBuilder(baseChain?)`: 创建 Completions 中间件构建器
+- `createMethodBuilder(baseChain?)`: 创建通用方法中间件构建器
+- `addMiddlewareName(middleware, name)`: 为中间件添加名称属性的辅助函数
+
+### 中间件注册表
+
+- `MiddlewareRegistry`: 所有注册中间件的集中访问点
+- `getMiddleware(name)`: 根据名称获取中间件
+- `getRegisteredMiddlewareNames()`: 获取所有注册的中间件名称
+- `DefaultCompletionsNamedMiddlewares`: 默认的 Completions 中间件链（NamedMiddleware 格式）
+
+## 类型安全
+
+构建器提供完整的 TypeScript 类型支持：
+
+- `CompletionsMiddlewareBuilder` 专门用于 `CompletionsMiddleware` 类型
+- `MethodMiddlewareBuilder` 用于通用的 `MethodMiddleware` 类型
+- 所有中间件操作都基于 `NamedMiddleware<TMiddleware>` 接口
+
+## 默认中间件链
+
+默认的 Completions 中间件执行顺序：
+
+1. `FinalChunkConsumerMiddleware` - 最终消费者
+2. `TransformCoreToSdkParamsMiddleware` - 参数转换
+3. `AbortHandlerMiddleware` - 中止处理
+4. `McpToolChunkMiddleware` - 工具处理
+5. `WebSearchMiddleware` - Web搜索处理
+6. `TextChunkMiddleware` - 文本处理
+7. `ThinkingTagExtractionMiddleware` - 思考标签提取处理
+8. `ThinkChunkMiddleware` - 思考处理
+9. `ResponseTransformMiddleware` - 响应转换
+10. `StreamAdapterMiddleware` - 流适配器
+11. `SdkCallMiddleware` - SDK调用
+
+## 在 AiProvider 中的使用
+
+```typescript
+export default class AiProvider {
+  public async completions(params: CompletionsParams): Promise<CompletionsResult> {
+    // 1. 构建中间件链
+    const builder = CompletionsMiddlewareBuilder.withDefaults()
+
+    // 2. 根据参数动态调整
+    if (params.enableCustomFeature) {
+      builder.insertAfter('StreamAdapterMiddleware', customFeatureMiddleware)
+    }
+
+    // 3. 应用中间件
+    const middlewares = builder.build()
+    const wrappedMethod = applyCompletionsMiddlewares(this.apiClient, this.apiClient.createCompletions, middlewares)
+
+    return wrappedMethod(params)
+  }
+}
+```
+
+## 注意事项
+
+1. **类型兼容性**：`MethodMiddleware` 和 `CompletionsMiddleware` 不兼容，需要使用对应的构建器
+2. **中间件名称**：所有中间件必须导出 `MIDDLEWARE_NAME` 常量用于标识
+3. **注册表管理**：新增中间件需要在 `register.ts` 中注册
+4. **默认链**：默认链通过 `DefaultCompletionsNamedMiddlewares` 提供，支持延迟加载避免循环依赖
+
+这种设计使得中间件链的构建既灵活又类型安全，同时保持了简洁的 API 接口。

+# Cherry Studio 中间件规范
+
+本文档定义了 Cherry Studio `aiCore` 模块中中间件的设计、实现和使用规范。目标是建立一个灵活、可维护且易于扩展的中间件系统。
+
+## 1. 核心概念
+
+### 1.1. 中间件 (Middleware)
+
+中间件是一个函数或对象，它在 AI 请求的处理流程中的特定阶段执行，可以访问和修改请求上下文 (`AiProviderMiddlewareContext`)、请求参数 (`Params`)，并控制是否将请求传递给下一个中间件或终止流程。
+
+每个中间件应该专注于一个单一的横切关注点，例如日志记录、错误处理、流适配、特性解析等。
+
+### 1.2. `AiProviderMiddlewareContext` (上下文对象)
+
+这是一个在整个中间件链执行过程中传递的对象，包含以下核心信息：
+
+- `_apiClientInstance: ApiClient<any,any,any>`: 当前选定的、已实例化的 AI Provider 客户端。
+- `_coreRequest: CoreRequestType`: 标准化的内部核心请求对象。
+- `resolvePromise: (value: AggregatedResultType) => void`: 用于在整个操作成功完成时解析 `AiCoreService` 返回的 Promise。
+- `rejectPromise: (reason?: any) => void`: 用于在发生错误时拒绝 `AiCoreService` 返回的 Promise。
+- `onChunk?: (chunk: Chunk) => void`: 应用层提供的流式数据块回调。
+- `abortController?: AbortController`: 用于中止请求的控制器。
+- 其他中间件可能读写的、与当前请求相关的动态数据。
+
+### 1.3. `MiddlewareName` (中间件名称)
+
+为了方便动态操作（如插入、替换、移除）中间件，每个重要的、可能被其他逻辑引用的中间件都应该有一个唯一的、可识别的名称。推荐使用 TypeScript 的 `enum` 来定义：
+
+```typescript
+// example
+export enum MiddlewareName {
+  LOGGING_START = 'LoggingStartMiddleware',
+  LOGGING_END = 'LoggingEndMiddleware',
+  ERROR_HANDLING = 'ErrorHandlingMiddleware',
+  ABORT_HANDLER = 'AbortHandlerMiddleware',
+  // Core Flow
+  TRANSFORM_CORE_TO_SDK_PARAMS = 'TransformCoreToSdkParamsMiddleware',
+  REQUEST_EXECUTION = 'RequestExecutionMiddleware',
+  STREAM_ADAPTER = 'StreamAdapterMiddleware',
+  RAW_SDK_CHUNK_TO_APP_CHUNK = 'RawSdkChunkToAppChunkMiddleware',
+  // Features
+  THINKING_TAG_EXTRACTION = 'ThinkingTagExtractionMiddleware',
+  TOOL_USE_TAG_EXTRACTION = 'ToolUseTagExtractionMiddleware',
+  MCP_TOOL_HANDLER = 'McpToolHandlerMiddleware',
+  // Finalization
+  FINAL_CHUNK_CONSUMER = 'FinalChunkConsumerAndNotifierMiddleware'
+  // Add more as needed
+}
+```
+
+中间件实例需要某种方式暴露其 `MiddlewareName`，例如通过一个 `name` 属性。
+
+### 1.4. 中间件执行结构
+
+我们采用一种灵活的中间件执行结构。一个中间件通常是一个函数，它接收 `Context`、`Params`，以及一个 `next` 函数（用于调用链中的下一个中间件）。
+
+```typescript
+// 简化形式的中间件函数签名
+type MiddlewareFunction = (
+  context: AiProviderMiddlewareContext,
+  params: any, // e.g., CompletionsParams
+  next: () => Promise<void> // next 通常返回 Promise 以支持异步操作
+) => Promise<void> // 中间件自身也可能返回 Promise
+
+// 或者更经典的 Koa/Express 风格 (三段式)
+// type MiddlewareFactory = (api?: MiddlewareApi) =>
+//                          (nextMiddleware: (ctx: AiProviderMiddlewareContext, params: any) => Promise<void>) =>
+//                              (context: AiProviderMiddlewareContext, params: any) => Promise<void>;
+// 当前设计更倾向于上述简化的 MiddlewareFunction，由 MiddlewareExecutor 负责 next 的编排。
+```
+
+`MiddlewareExecutor` (或 `applyMiddlewares`) 会负责管理 `next` 的调用。
+
+## 2. `MiddlewareBuilder` (通用中间件构建器)
+
+为了动态构建和管理中间件链，我们引入一个通用的 `MiddlewareBuilder` 类。
+
+### 2.1. 设计理念
+
+`MiddlewareBuilder` 提供了一个流式 API，用于以声明式的方式构建中间件链。它允许从一个基础链开始，然后根据特定条件添加、插入、替换或移除中间件。
+
+### 2.2. API 概览
+
+```typescript
+class MiddlewareBuilder {
+  constructor(baseChain?: Middleware[])
+
+  add(middleware: Middleware): this
+  prepend(middleware: Middleware): this
+  insertAfter(targetName: MiddlewareName, middlewareToInsert: Middleware): this
+  insertBefore(targetName: MiddlewareName, middlewareToInsert: Middleware): this
+  replace(targetName: MiddlewareName, newMiddleware: Middleware): this
+  remove(targetName: MiddlewareName): this
+
+  build(): Middleware[] // 返回构建好的中间件数组
+
+  // 可选：直接执行链
+  execute(
+    context: AiProviderMiddlewareContext,
+    params: any,
+    middlewareExecutor: (chain: Middleware[], context: AiProviderMiddlewareContext, params: any) => void
+  ): void
+}
+```
+
+### 2.3. 使用示例
+
+```typescript
+// 1. 定义一些中间件实例 (假设它们有 .name 属性)
+const loggingStart = { name: MiddlewareName.LOGGING_START, fn: loggingStartFn }
+const requestExec = { name: MiddlewareName.REQUEST_EXECUTION, fn: requestExecFn }
+const streamAdapter = { name: MiddlewareName.STREAM_ADAPTER, fn: streamAdapterFn }
+const customFeature = { name: MiddlewareName.CUSTOM_FEATURE, fn: customFeatureFn } // 假设自定义
+
+// 2. 定义一个基础链 (可选)
+const BASE_CHAIN: Middleware[] = [loggingStart, requestExec, streamAdapter]
+
+// 3. 使用 MiddlewareBuilder
+const builder = new MiddlewareBuilder(BASE_CHAIN)
+
+if (params.needsCustomFeature) {
+  builder.insertAfter(MiddlewareName.STREAM_ADAPTER, customFeature)
+}
+
+if (params.isHighSecurityContext) {
+  builder.insertBefore(MiddlewareName.REQUEST_EXECUTION, высокоSecurityCheckMiddleware)
+}
+
+if (params.overrideLogging) {
+  builder.replace(MiddlewareName.LOGGING_START, newSpecialLoggingMiddleware)
+}
+
+// 4. 获取最终链
+const finalChain = builder.build()
+
+// 5. 执行 (通过外部执行器)
+// middlewareExecutor(finalChain, context, params);
+// 或者 builder.execute(context, params, middlewareExecutor);
+```
+
+## 3. `MiddlewareExecutor` / `applyMiddlewares` (中间件执行器)
+
+这是负责接收 `MiddlewareBuilder` 构建的中间件链并实际执行它们的组件。
+
+### 3.1. 职责
+
+- 接收 `Middleware[]`, `AiProviderMiddlewareContext`, `Params`。
+- 按顺序迭代中间件。
+- 为每个中间件提供正确的 `next` 函数，该函数在被调用时会执行链中的下一个中间件。
+- 处理中间件执行过程中的Promise（如果中间件是异步的）。
+- 基础的错误捕获（具体错误处理应由链内的 `ErrorHandlingMiddleware` 负责）。
+
+## 4. 在 `AiCoreService` 中使用
+
+`AiCoreService` 中的每个核心业务方法 (如 `executeCompletions`) 将负责：
+
+1.  准备基础数据：实例化 `ApiClient`，转换 `Params` 为 `CoreRequest`。
+2.  实例化 `MiddlewareBuilder`，可能会传入一个特定于该业务方法的基础中间件链。
+3.  根据 `Params` 和 `CoreRequest` 中的条件，调用 `MiddlewareBuilder` 的方法来动态调整中间件链。
+4.  调用 `MiddlewareBuilder.build()` 获取最终的中间件链。
+5.  创建完整的 `AiProviderMiddlewareContext` (包含 `resolvePromise`, `rejectPromise` 等)。
+6.  调用 `MiddlewareExecutor` (或 `applyMiddlewares`) 来执行构建好的链。
+
+## 5. 组合功能
+
+对于组合功能（例如 "Completions then Translate"）：
+
+- 不推荐创建一个单一、庞大的 `MiddlewareBuilder` 来处理整个组合流程。
+- 推荐在 `AiCoreService` 中创建一个新的方法，该方法按顺序 `await` 调用底层的原子 `AiCoreService` 方法（例如，先 `await this.executeCompletions(...)`，然后用其结果 `await this.translateText(...)`）。
+- 每个被调用的原子方法内部会使用其自身的 `MiddlewareBuilder` 实例来构建和执行其特定阶段的中间件链。
+- 这种方式最大化了复用，并保持了各部分职责的清晰。
+
+## 6. 中间件命名和发现
+
+为中间件赋予唯一的 `MiddlewareName` 对于 `MiddlewareBuilder` 的 `insertAfter`, `insertBefore`, `replace`, `remove` 等操作至关重要。确保中间件实例能够以某种方式暴露其名称（例如，一个 `name` 属性）。
