-└── services/             # 客户端服务 (调用 tRPC 或直接访问 Model)
-```
-
-## 核心架构分层
-
-LobeChat 的后端设计注重模块化、可测试性和灵活性，以适应不同的运行环境（如浏览器端 PGLite、服务端远程 PostgreSQL 以及 Electron 桌面应用）。
-
-其主要分层如下：
-
-1.  客户端服务层 (`src/services`):
-    - 位于 src/services/。
-    - 这是客户端业务逻辑的核心层，负责封装各种业务操作和数据处理逻辑。
-    - 环境适配: 根据不同的运行环境，服务层会选择合适的数据访问方式：
-      - 本地数据库模式: 直接调用 `Model` 层进行数据操作，适用于浏览器 PGLite 和本地 Electron 应用。
-      - 远程数据库模式: 通过 `tRPC` 客户端调用服务端 API，适用于需要云同步的场景。
-    - 类型转换: 对于简单的数据类型转换，直接在此层进行类型断言，如 `this.pluginModel.query() as Promise<LobeTool[]>`
-    - 每个服务模块通常包含 `client.ts`（本地模式）、`server.ts`（远程模式）和 `type.ts`（接口定义）文件，在实现时应该确保本地模式和远程模式业务逻辑实现一致，只是数据库不同。
-
-2.  API 接口层 (`TRPC`):
-    - 位于 src/server/routers/
-    - 使用 `tRPC` 构建类型安全的 API。Router 根据运行时环境（如 Edge Functions, Node.js Lambda）进行组织。
-    - 负责接收客户端请求，并将其路由到相应的 `Service` 层进行处理。
-    - 新建 lambda 端点时可以参考 src/server/routers/lambda/\_template.ts
-
-3.  仓库层 (`Repositories`):
-    - 位于 src/database/repositories/。
-    - 主要处理复杂的跨表查询和数据聚合逻辑，特别是当需要从多个 `Model` 获取数据并进行组合时。
-    - 与 `Model` 层不同，`Repository` 层专注于复杂的业务查询场景，而不涉及简单的领域模型转换。
-    - 当业务逻辑涉及多表关联、复杂的数据统计或需要事务处理时，会使用 `Repository` 层。
-    - 如果数据操作简单（仅涉及单个 `Model`），则通常直接在 `src/services` 层调用 `Model` 并进行简单的类型断言。
-
-4.  模型层 (`Models`):
-    - 位于 src/database/models/ (例如 src/database/models/plugin.ts 和 src/database/models/document.ts)。
-    - 提供对数据库中各个表（由 src/database/schemas/ 中的 Drizzle ORM schema 定义）的基本 CRUD (创建、读取、更新、删除) 操作和简单的查询能力。
-    - `Model` 类专注于单个数据表的直接操作，不涉及复杂的领域模型转换，这些转换通常在上层的 `src/services` 中通过类型断言完成。
-    - model（例如 Topic） 层接口经常需要从对应的 schema 层导入 NewTopic 和 TopicItem
-    - 创建新的 model 时可以参考 src/database/models/\_template.ts
-
-5.  数据库 (`Database`):
-    - 客户端模式 (浏览器/PWA): 使用 PGLite (基于 WASM 的 PostgreSQL)，数据存储在用户浏览器本地。
-    - 服务端模式 (云部署): 使用远程 PostgreSQL 数据库。
-    - Electron 桌面应用:
-      - Electron 客户端会启动一个本地 Node.js 服务。
-      - 本地服务通过 `tRPC` 与 Electron 的渲染进程通信。
-      - 数据库选择依赖于是否开启云同步功能：
-        - 云同步开启: 连接到远程 PostgreSQL 数据库。
-        - 云同步关闭: 使用 PGLite (通过 Node.js 的 WASM 实现) 在本地存储数据。
-
-## 数据流向说明
-
-### 浏览器/PWA 模式
-
-```
-UI (React) → Zustand action -> Client Service → Model Layer → PGLite (本地数据库)
-```
-
-### 服务端模式
-
-```
-UI (React) → Zustand action → Client Service -> TRPC Client → TRPC Routers  → Repositories/Models → Remote PostgreSQL
-```
-
-### Electron 桌面应用模式
-
-```
-UI (Electron Renderer) → Zustand action → Client Service -> TRPC Client → 本地 Node.js 服务 → TRPC Routers → Repositories/Models → PGLite/Remote PostgreSQL (取决于云同步设置)
-```
-
-## 服务层 (Server Services)
-
-- 位于 src/server/services/。
-- 核心职责是封装独立的、可复用的业务逻辑单元。这些服务应易于测试。
-- 平台差异抽象: 一个关键特性是通过其内部的 `impls` 子目录（例如 src/server/services/file/impls 包含 s3.ts 和 local.ts）来抹平不同运行环境带来的差异（例如云端使用 S3 存储，桌面版使用本地文件系统）。这使得上层（如 `tRPC` routers）无需关心底层具体实现。
-- 目标是使 `tRPC` router 层的逻辑尽可能纯粹，专注于请求处理和业务流程编排。
-- 服务可能会调用 `Repository` 层或直接调用 `Model` 层进行数据持久化和检索，也可能调用其他服务。
-
-## 最佳实践 (Best Practices)
-
-### 数据库操作封装原则
-
-**连续的数据库操作应该封装到 Model 层**
-
-当业务逻辑涉及多个相关的数据库操作时，建议将这些操作封装到 Model 层中，而不是在上层（Service 或 Router 层）中进行多次数据库调用。
-
-**优势：**
-
-- **代码复用**: Client DB 环境的 service 实现和 Server DB 的 lambda 层实现可以复用相同的 Model 方法
-- **事务一致性**: 相关的数据库操作可以在同一个方法中管理，便于维护数据一致性
-- **性能优化**: 减少数据库连接次数，提高查询效率
-- **职责清晰**: Model 层专注数据访问，上层专注业务协调
-
-**示例：**
-
-```typescript
-// ✅ 推荐：在 Model 层封装连续的数据库操作
-class GenerationBatchModel {
-  async delete(id: string): Promise<{ deletedBatch: BatchItem; thumbnailUrls: string[] }> {
-    // 1. 查询相关数据
-    const batchWithGenerations = await this.db.query.generationBatches.findFirst({...});
-
-    // 2. 收集需要处理的数据
-    const thumbnailUrls = [...];
-
-    // 3. 执行删除操作
-    const [deletedBatch] = await this.db.delete(generationBatches)...;
-
-    return { deletedBatch, thumbnailUrls };
-  }
-}
-
-// ✅ 上层使用简洁
-const { thumbnailUrls } = await model.delete(id);
-await fileService.deleteFiles(thumbnailUrls);
-```
-
-### 文件操作与数据库操作的执行顺序
-
-**删除操作原则：数据库删除在前，文件删除在后**
-
-当业务逻辑同时涉及数据库记录和文件系统操作时，应该遵循"数据库优先"的原则。
-
-**原因：**
-
-- **用户体验优先**: 如果先删除文件再删除数据库记录，可能出现文件已删除但数据库记录仍存在的情况，用户访问时会遇到文件不存在的错误
-- **影响程度较小**: 如果先删除数据库记录再删除文件，即使文件删除失败，用户也看不到这个记录，只是造成一些存储空间浪费，对用户体验影响更小
-- **数据一致性**: 数据库记录是业务逻辑的核心，应该优先保证其一致性
-
-**示例：**
-
-```typescript
-// ✅ 推荐：先删除数据库记录，再删除文件
-async deleteGeneration(id: string) {
-  // 1. 先删除数据库记录
-  const deletedGeneration = await generationModel.delete(id);
-
-  // 2. 再删除相关文件
-  if (deletedGeneration.asset?.thumbnailUrl) {
-    await fileService.deleteFile(deletedGeneration.asset.thumbnailUrl);
-  }
-}
-
-// ❌ 不推荐：先删除文件
-async deleteGeneration(id: string) {
-  const generation = await generationModel.findById(id);
-
-  // 如果这里删除成功，但后面数据库删除失败，用户会遇到访问错误
-  await fileService.deleteFile(generation.asset.thumbnailUrl);
-  await generationModel.delete(id); // 可能失败
-}
-```
-
-**创建操作原则：数据库创建在前，文件操作在后**
-
-创建操作同样应该优先处理数据库记录，确保数据的一致性和完整性。

-# Role Description
-
-- You are a senior full-stack engineer skilled in performance optimization, security, and design systems.
-- You excel at reviewing code and providing constructive feedback.
-- Your task is to review submitted Git diffs **in Chinese** and return a structured review report.
-- Review style: concise, direct, focused on what matters most, with actionable suggestions.
-
-## Before the Review
-
-Gather the modified code and context. Please strictly follow the process below:
-
-1. Use `read_file` to read [package.json](mdc:package.json)
-2. Use terminal to run command `git diff HEAD | cat` to obtain the diff and list the changed files. If you recieived empty result, run the same command once more.
-3. Use `read_file` to open each changed file.
-4. Use `read_file` to read [rules-attach.mdc](mdc:.cursor/rules/rules-attach.mdc). Even if you think it's unnecessary, you must read it.
-5. combine changed files, step3 and `agent_requestable_workspace_rules`, list the rules which need to read
-6. Use `read_file` to read the rules list in step 5
-
-## Review
-
-### Code Style
-
-read [typescript.mdc](mdc:.cursor/rules/typescript.mdc) for the consolidated project code style and optimization rules.
-
-### Code Optimization
-
-The optimization checklist has been consolidated into [typescript.mdc](mdc:.cursor/rules/typescript.mdc): loops, debouncing/throttling, design system components, theming tokens, concurrency with `Promise.*`, minimal DB column selection, and package reuse.
-
-### Obvious Bugs
-
-- Do not silently swallow errors in `catch` blocks; at minimum, log them.
-- Revert temporary code used only for testing (e.g., debug logs, temporary configs).
-- Remove empty handlers (e.g., an empty `onClick`).
-- Confirm the UI degrades gracefully for unauthenticated users.
-- Don't leave any debug logs in the code (except when using the `debug` module properly).
-  - When using the `debug` module, avoid `import { log } from 'debug'` as it logs directly to console. Use proper debug namespaces instead.
-- Check logs for sensitive information like api key, etc
-
-## After the Review: output
-
-1. Summary
-   - Start with a brief explanation of what the change set does.
-   - Summarize the changes for each modified file (or logical group).
-2. Comments Issues
-   - List the most critical issues first.
-   - Use an ordered list, which will be convenient for me to reference later.
-   - For each issue:
-     - Mark severity tag (`❌ Must fix`, `⚠️ Should fix`, `💅 Nitpick`)
-     - Provode file path to the relevant file.
-     - Provide recommended fix
-   - End with a **git commit** command, instruct the author to run it.
-     - We use gitmoji to label commit messages, format: [emoji] <type>(<scope>): <subject>

-# Guide to Optimize Output(Response) Rendering
-
-## File Path and Code Symbol Rendering
-
-- When rendering file paths, use backtick wrapping instead of markdown links so they can be parsed as clickable links in Cursor IDE.
-  - Good: `src/components/Button.tsx`
-  - Bad: [src/components/Button.tsx](src/components/Button.tsx)
-
-- Don't use line and column number in file path, this will make file path not clickable in Cursor IDE.
-  - Good: `src/components/Button.tsx` `10:20` (add a space between the file path and the line and column number)
-  - Bad: `src/components/Button.tsx:10:20`
-
-- When rendering functions, variables, or other code symbols, use backtick wrapping so they can be parsed as navigable links in Cursor IDE
-  - Good: The `useState` hook in `MyComponent`
-  - Bad: The useState hook in MyComponent
-
-## Markdown Render
-
-- don't use br tag to wrap in table cell
-
-## Terminal Command Output
-
-- If terminal commands don't produce output, it's likely due to paging issues. Try piping the command to `cat` to ensure full output is displayed.
-  - Good: `git show commit_hash -- file.txt | cat`
-  - Good: `git log --oneline | cat`
-  - Reason: Some git commands use pagers by default, which may prevent output from being captured properly

 ## Architecture Map
 
-- Presentation: `src/features`, `src/components`, `src/layout` — UI composition, global providers
-- State: `src/store` — Zustand slices, selectors, middleware
-- Client Services: `src/services/<domain>/{client|server}.ts` — client: PGLite; server: tRPC bridge
-- API Routers: `src/app/(backend)/webapi` (REST), `src/app/(backend)/trpc/{edge|lambda|async|desktop|tools}`; Lambda router triggers Async router for long-running tasks (e.g., image)
-- Server Services: `src/server/services` (business logic), `src/server/modules` (infra adapters)
-- Data Access: `packages/database/src/{schemas,models,repositories}` — Schema (Drizzle), Model (CRUD), Repository (complex queries)
-- Integrations: `src/libs` — analytics, auth, trpc, logging, runtime helpers
+- UI Components: `src/components`, `src/features`
+- Global providers: `src/layout`
+- Zustand stores: `src/store`
+- Client Services: `src/services/`
+  - clientDB: `src/services/<domain>/client.ts`
+  - serverDB: `src/services/<domain>/server.ts`
+- API Routers:
+  - `src/app/(backend)/webapi` (REST)
+  - `src/server/routers/{edge|lambda|async|desktop|tools}` (tRPC)
+- Server:
+  - Services(can access serverDB): `src/server/services`
+  - Modules(can't access db): `src/server/modules` (Server only Third-party Service Module)
+- Database:
+  - Schema (Drizzle): `packages/database/src/schemas`
+  - Model (CRUD): `packages/database/src/models`

 ## Data Flow Architecture
 
-### Unified Flow Pattern
-
-```
-UI Layer → State Management → Client Service → [Environment Branch] → Database
-   ↓              ↓               ↓                    ↓                ↓
- React         Zustand     Environment         Local/Remote        PGLite/
-Components      Store      Adaptation            Routing          PostgreSQL
-```
-
-### Environment-Specific Routing
-
-| Mode            | UI       | Service Route          | Database            |
-| --------------- | -------- | ---------------------- | ------------------- |
-| **Browser/PWA** | React    | Direct Model Access    | PGLite (Local)      |
-| **Server**      | React    | tRPC → Server Services | PostgreSQL (Remote) |
-| **Desktop**     | Electron | tRPC → Local Node.js   | PGLite/PostgreSQL\* |
-
-_\*Depends on cloud sync configuration_
-
-### Key Characteristics
-
-- **Type Safety**: End-to-end type safety via tRPC and Drizzle ORM
-- **Local/Remote Dual Mode**: PGLite enables user data ownership and local control
-
-## Quick Map
-
-- App Routes: `src/app` — UI routes (App Router) and backend routes under `(backend)`
-- Web API: `src/app/(backend)/webapi` — REST-like endpoints
-- tRPC Routers: `src/server/routers` — typed RPC endpoints by runtime
-- Client Services: `src/services` — environment-adaptive client-side business logic
-- Server Services: `src/server/services` — platform-agnostic business logic
-- Database: `packages/database` — schemas/models/repositories/migrations
-- State: `src/store` — Zustand stores and slices
-- Integrations: `src/libs` — analytics/auth/trpc/logging/runtime helpers
-- Tools: `src/tools` — built-in tool system
-
-## Common Tasks
-
-- Add Web API route: `src/app/(backend)/webapi/<module>/route.ts`
-- Add tRPC endpoint: `src/server/routers/{edge|lambda|desktop}/...`
-- Add client/server service: `src/services/<domain>/{client|server}.ts` (client: PGLite; server: tRPC)
-- Add server service: `src/server/services/<domain>`
-- Add a new model/provider: `src/config/modelProviders/<provider>.ts` + `packages/model-bank/src/aiModels/<provider>.ts` + `packages/model-runtime/src/<provider>/index.ts`
-- Add DB schema/model/repository: `packages/database/src/{schemas|models|repositories}`
-- Add Zustand slice: `src/store/<domain>/slices`
-
-## Env Modes
-
-- `NEXT_PUBLIC_CLIENT_DB`: selects client DB mode (e.g., `pglite`) vs server-backed
-- `NEXT_PUBLIC_IS_DESKTOP_APP`: enables desktop-specific routes and behavior
-- `NEXT_PUBLIC_SERVICE_MODE`: controls service routing preference (client/server)
-
-## Boundaries
-
-- Keep client logic in `src/services`; server-only logic stays in `src/server/services`
-- Don’t mix Web API (`webapi/`) with tRPC (`src/server/routers/`)
-- Place business UI under `src/features`, global reusable UI under `src/components`
+- **Browser/PWA**: React UI → Client Service → Direct Model Access → PGLite (Web WASM)
+- **Server**: React UI → Client Service → tRPC Lambda → Server Services → PostgreSQL (Remote)
+- **Desktop**:
+  - Cloud sync disabled: Electron UI → Client Service → tRPC Lambda → Local Server Services → PGLite (Node WASM)
+  - Cloud sync enabled: Electron UI → Client Service → tRPC Lambda → Cloud Server Services → PostgreSQL (Remote)

-You are an expert in UI/UX design, proficient in web interaction patterns, responsive design, accessibility, and user behavior optimization. You excel at improving user retention and paid conversion rates through various interaction details.
-
-## Problem Solving
-
-- When modifying existing code, clearly describe the differences and reasons for the changes
-- Provide alternative solutions that may be better overall or superior in specific aspects
-- Provide optimization suggestions for deprecated API usage
-- Cite sources whenever possible at the end, not inline
-- When you provide multiple solutions, provide the recommended solution first, and note it as `Recommended`
-- Express uncertainty when there might not be a correct answer, instead of take action by guessing and assuming
-
-## Code Implementation
-
-- Focus on maintainable over being performant
-- Be sure to reference file path
-- If doc links or required files are missing, ask for them before proceeding with the task rather than making assumptions
-- If you're unable to get valid result when using tools, please clearly state in the output

+- use the most accurate type possible (e.g., prefer `Record<PropertyKey, unknown>` over `object` and `any`).
 - prefer `interface` over `type` for object shapes (e.g., React component props). Keep `type` for unions, intersections, and utility types.

-- prefer `@ts-expect-error` over `@ts-ignore`
-- prefer `Record<string, any>` over `any`
-
-- **Avoid unnecessary null checks**: Before adding `xxx !== null`, `?.`, `??`, or `!.`, read the type definition to confirm the necessary. **Example:**
-
-  ```typescript
-  // ❌ Wrong: budget.spend and budget.maxBudget is number, not number | null
-  if (budget.spend !== null && budget.maxBudget !== null && budget.spend >= budget.maxBudget) {
