 - **Keep it clear**: Write code that is easy to read, maintain, and explain.
 - **Match the house style**: Reuse existing patterns, naming, and conventions.
 - **Search smart**: Prefer `ast-grep` for semantic queries; fall back to `rg`/`grep` when needed.
+- **Build with Tailwind CSS & Shadcn UI**: Use components from `@packages/ui` (Shadcn UI + Tailwind CSS) for every new UI component; never add `antd` or `styled-components`.
 - **Log centrally**: Route all logging through `loggerService` with the right context—no `console.log`.
 - **Research via subagent**: Lean on `subagent` for external docs, APIs, news, and references.
 - **Always propose before executing**: Before making any changes, clearly explain your planned approach and wait for explicit user approval to ensure alignment and prevent unwanted modifications.

 - **Renderer Process** (`src/renderer/`): React UI with Redux state management
 - **Preload Scripts** (`src/preload/`): Secure IPC bridge
 
-### Key Components
-- **AI Core** (`src/renderer/src/aiCore/`): Middleware pipeline for multiple AI providers.
-- **Services** (`src/main/services/`): MCPService, KnowledgeService, WindowService, etc.
-- **Build System**: Electron-Vite with experimental rolldown-vite, yarn workspaces.
-- **State Management**: Redux Toolkit (`src/renderer/src/store/`) for predictable state.
+### Key Architectural Components
+
+#### Main Process Services (`src/main/services/`)
+
+- **MCPService**: Model Context Protocol server management
+- **KnowledgeService**: Document processing and knowledge base management
+- **FileStorage/S3Storage/WebDav**: Multiple storage backends
+- **WindowService**: Multi-window management (main, mini, selection windows)
+- **ProxyManager**: Network proxy handling
+- **SearchService**: Full-text search capabilities
+
+#### AI Core (`src/renderer/src/aiCore/`)
+
+- **Middleware System**: Composable pipeline for AI request processing
+- **Client Factory**: Supports multiple AI providers (OpenAI, Anthropic, Gemini, etc.)
+- **Stream Processing**: Real-time response handling
+
+#### Data Management
+
+- **Cache System**: Three-layer caching (memory/shared/persist) with React hooks integration
+- **Preferences**: Type-safe configuration management with multi-window synchronization
+- **User Data**: SQLite-based storage with Drizzle ORM for business data
+
+#### Knowledge Management
+
+- **Embeddings**: Vector search with multiple providers (OpenAI, Voyage, etc.)
+- **OCR**: Document text extraction (system OCR, Doc2x, Mineru)
+- **Preprocessing**: Document preparation pipeline
+- **Loaders**: Support for various file formats (PDF, DOCX, EPUB, etc.)
+
+### Build System
+
+- **Electron-Vite**: Development and build tooling (v4.0.0)
+- **Rolldown-Vite**: Using experimental rolldown-vite instead of standard vite
+- **Workspaces**: Monorepo structure with `packages/` directory
+- **Multiple Entry Points**: Main app, mini window, selection toolbar
+- **Styled Components**: CSS-in-JS styling with SWC optimization
+
+### Testing Strategy
+
+- **Vitest**: Unit and integration testing
+- **Playwright**: End-to-end testing
+- **Component Testing**: React Testing Library
+- **Coverage**: Available via `yarn test:coverage`
+
+### Key Patterns
+
+- **IPC Communication**: Secure main-renderer communication via preload scripts
+- **Service Layer**: Clear separation between UI and business logic
+- **Plugin Architecture**: Extensible via MCP servers and middleware
+- **Multi-language Support**: i18n with dynamic loading
+- **Theme System**: Light/dark themes with custom CSS variables
+
+### UI Design
+
+The project is in the process of migrating from antd & styled-components to Tailwind CSS and Shadcn UI. Please use components from `@packages/ui` to build UI components. The use of antd and styled-components is prohibited.
+
+UI Library: `@packages/ui`
+
+### Database Architecture
+
+- **Database**: SQLite (`cherrystudio.sqlite`) + libsql driver
+- **ORM**: Drizzle ORM with comprehensive migration system
+- **Schemas**: Located in `src/main/data/db/schemas/` directory
+
+#### Database Standards
+
+- **Table Naming**: Use singular form with snake_case (e.g., `topic`, `message`, `app_state`)
+- **Schema Exports**: Export using `xxxTable` pattern (e.g., `topicTable`, `appStateTable`)
+- **Field Definition**: Drizzle auto-infers field names, no need to add default field names
+- **JSON Fields**: For JSON support, add `{ mode: 'json' }`, refer to `preference.ts` table definition
+- **JSON Serialization**: For JSON fields, no need to manually serialize/deserialize when reading/writing to database, Drizzle handles this automatically
+- **Timestamps**: Use existing `crudTimestamps` utility
+- **Migrations**: Generate via `yarn run migrations:generate`
+
+## Data Access Patterns
+
+The application uses three distinct data management systems. Choose the appropriate system based on data characteristics:
+
+### Cache System
+- **Purpose**: Temporary data that can be regenerated
+- **Lifecycle**: Component-level (memory), window-level (shared), or persistent (survives restart)
+- **Use Cases**: API response caching, computed results, temporary UI state
+- **APIs**: `useCache`, `useSharedCache`, `usePersistCache` hooks, or `cacheService`
+
+### Preference System
+- **Purpose**: User configuration and application settings
+- **Lifecycle**: Permanent until user changes
+- **Use Cases**: Theme, language, editor settings, user preferences
+- **APIs**: `usePreference`, `usePreferences` hooks, or `preferenceService`
+
+### User Data API
+- **Purpose**: Core business data (conversations, files, notes, etc.)
+- **Lifecycle**: Permanent business records
+- **Use Cases**: Topics, messages, files, knowledge base, user-generated content
+- **APIs**: `useDataApi` hook or `dataApiService` for direct calls
+
+### Selection Guidelines
+
+- **Use Cache** for data that can be lost without impact (computed values, API responses)
+- **Use Preferences** for user settings that affect app behavior (UI configuration, feature flags)
+- **Use User Data API** for irreplaceable business data (conversations, documents, user content)
+
+## Logging Standards
+
+### Usage
 
-### Logging
 ```typescript
 import { loggerService } from '@logger'
 const logger = loggerService.withContext('moduleName')

+# 模型和供应商参数化配置实现方案
+
+## 📋 项目概述
+
+本文档描述了在 `@packages/catalog/` 下实现模型和供应商参数化配置的方案，目标是将现有的硬编码逻辑重构为元数据驱动的配置系统。
+
+## 🎯 目标
+
+### 主要目标
+- 将硬编码的模型识别逻辑转换为 JSON 配置驱动
+- 解决"同一模型在不同供应商下有差异"的问题
+- 提供类型安全的配置系统（使用 Zod）
+- 支持未来通过配置更新添加新模型
+
+### 痛点解决
+- **当前问题**：`src/renderer/src/config/models/` 下复杂的正则表达式和硬编码逻辑
+- **期望状态**：配置以 JSON 形式存在，代码中使用 Zod Schema 验证
+- **可维护性**：新模型发布时只需更新 JSON 配置，无需修改代码
+
+## 🏗️ 架构设计
+
+### 三层分离的元数据架构
+
+```
+1. Base Model Catalog (models/*.json)
+   ├─ 模型基础信息（ID、能力、模态、限制、价格）
+   └─ 官方/标准配置
+
+2. Provider Catalog (providers/*.json)
+   ├─ 供应商特性（端点支持、API 兼容性）
+   └─ 认证和定价模型
+
+3. Provider Model Overrides (overrides/*.json)
+   ├─ 供应商对特定模型的覆盖
+   └─ 解决"同一模型不同供应商差异"问题
+```
+
+### 简化后的文件结构

+
+```typescript

+  }).optional(),
+
+  // 限制覆盖
+  limits: z.object({

+
+## 🔄 实现计划
+
+### Phase 1: 基础架构 (2-3 days)
+
+**目标**：建立核心架构和类型系统
+
+**任务**：
+1. **Schema 定义**
+   - 实现 `model.schema.ts`、`provider.schema.ts`、`override.schema.ts`
+   - 所有 Schema 使用 Zod 验证
+   - 导出 TypeScript 类型
+
+2. **配置加载器**
+   ```typescript
+   // packages/catalog/src/services/ConfigLoader.ts
+   export class ConfigLoader {
+     loadModels(): ModelConfig[]
+     loadProviders(): ProviderConfig[]
+     loadOverrides(): ProviderModelOverride[]
+     validate(): boolean
+   }
+   ```
+
+3. **目录服务**
+   ```typescript
+   // packages/catalog/src/services/CatalogService.ts
+   export class CatalogService {
+     // 实现所有查询 API
+   }
+   ```
+
+**验收标准**：
+- ✅ 所有 Schema 定义完成，通过 Zod 验证
+- ✅ ConfigLoader 可以加载和验证 JSON 文件
+- ✅ CatalogService 基础 API 实现
+- ✅ 单元测试覆盖核心功能
+
+### Phase 2: 数据迁移 (1-2 days)
+
+**目标**：从现有硬编码逻辑生成 JSON 配置
+
+**任务**：
+1. **迁移工具**
+   ```typescript
+   // packages/catalog/src/utils/migrate.ts
+   export class MigrationTool {
+     // 从 src/renderer/src/config/models/ 提取模型配置
+     extractModelConfigs(): ModelConfig[]
+
+     // 提取供应商配置
+     extractProviderConfigs(): ProviderConfig[]
+
+     // 写入 JSON 文件
+     writeConfigs(models: ModelConfig[], providers: ProviderConfig[]): void
+
+     // 简单验证
+     validate(): boolean
+   }
+   ```
+
+2. **迁移脚本**
+   ```bash
+   # 运行迁移
+   yarn catalog:migrate
+   ```
+
+3. **手动审核**
+   - 检查生成的配置文件
+   - 补充缺失的价格和限制信息
+   - 调整不准确的能力定义
+
+**验收标准**：
+- ✅ 迁移工具能够提取现有配置
+- ✅ 生成的配置通过 Schema 验证
+- ✅ 手动审核完成，配置准确
+
+### Phase 3: 集成替换 (2-3 days)
+
+**目标**：替换现有硬编码逻辑
+
+**任务**：
+1. **向后兼容层**
+   ```typescript
+   // packages/catalog/src/index.ts
+   export const isFunctionCallingModel = (model: Model): boolean =>
+     catalog.hasCapability(model.id, 'FUNCTION_CALL', model.provider)
+   ```
+
+2. **逐步替换**
+   - 替换 `src/renderer/src/config/models/` 中的函数
+   - 更新所有调用点
+   - 确保测试通过
+
+3. **集成测试**
+   - 端到端测试
+   - 性能测试
+   - 兼容性测试
+
+**验收标准**：
+- ✅ 所有现有测试通过
+- ✅ 新配置系统与旧系统行为一致
+- ✅ 性能不低于原有实现
+
+### 延迟实现 ⏸️
+
+以下功能在初期版本不实现，等待实际需求：
+
+- ⏸️ **在线配置更新**：等到有用户需求再实现
+- ⏸️ **复杂缓存机制**：等出现性能问题再优化
+- ⏸️ **配置版本控制**：简化为文件级别的版本号
+
+## 🧪 测试策略
+
+### 测试覆盖
+
+1. **Schema 测试**
+   ```typescript
+   describe('ModelConfig Schema', () => {
+     it('validates correct config', () => {
+       expect(() => ModelConfigSchema.parse(validConfig)).not.toThrow()
+     })
+
+     it('rejects invalid config', () => {
+       expect(() => ModelConfigSchema.parse(invalidConfig)).toThrow()
+     })
+   })
+   ```
+
+2. **服务测试**
+   ```typescript
+   describe('CatalogService', () => {
+     it('returns model with overrides applied', () => {
+       const model = catalog.getModel('claude-3-5-sonnet', 'openrouter')
+       expect(model?.pricing).toEqual(expectedPricing)
+     })
+
+     it('checks capabilities correctly', () => {
+       expect(catalog.hasCapability('gpt-4', 'FUNCTION_CALL')).toBe(true)
+     })
+   })
+   ```
+
+3. **兼容性测试**
+   ```typescript
+   describe('Backward Compatibility', () => {
+     it('produces same results as legacy', () => {
+       expect(isFunctionCallingModel(testModel)).toBe(legacyResult)
+     })
+   })
+   ```
+
+## 📖 使用指南
+
+### 基本用法
+
+```typescript
+import { catalog } from '@cherrystudio/catalog'
+
+// 检查模型能力
+const canCallFunctions = catalog.hasCapability('gpt-4', 'FUNCTION_CALL')
+const canReason = catalog.hasCapability('o1-preview', 'REASONING')
+
+// 获取模型配置
+const modelConfig = catalog.getModel('claude-3-5-sonnet', 'openrouter')
+
+// 查找模型
+const visionModels = catalog.findModels({
+  capabilities: ['IMAGE_RECOGNITION'],
+  providers: ['anthropic', 'openai']
+})
+
+// 检查供应商能力
+const hasMapping = catalog.hasProviderCapability('openrouter', 'MODEL_MAPPING')
+```
+
+### 供应商查询
+
+```typescript
+// 查找具有特定能力的供应商
+const providersWithFallback = catalog.findProviders({
+  capabilities: ['FALLBACK_ROUTING', 'AUTO_RETRY']
+})
+
+// 查找统一定价的供应商
+const unifiedPricingProviders = catalog.findProviders({
+  pricingModel: 'UNIFIED'
+})
+```
+
+## 📝 维护指南
+
+### 添加新模型
+
+1. 编辑对应的模型配置文件
+2. 添加模型信息
+3. 运行验证：`yarn catalog:validate`
+4. 提交 PR
+
+### 添加新供应商
+
+1. 编辑 `providers.json`
+2. 添加供应商配置
+3. 如需覆盖，添加到 `overrides.json`
+4. 验证并提交
+
+## 🔧 开发工具
+
+### 命令行
+
+```json
+{
+  "scripts": {
+    "catalog:validate": "tsx scripts/validate.ts",
+    "catalog:migrate": "tsx scripts/migrate.ts",
+    "catalog:test": "vitest run",
+    "catalog:build": "tsdown"
+  }
+}
+```
+
+## 📚 迁移对照表
+
+| 旧函数 | 新 API |
+|--------|--------|
+| `isFunctionCallingModel(model)` | `catalog.hasCapability(model.id, 'FUNCTION_CALL', model.provider)` |
+| `isReasoningModel(model)` | `catalog.hasCapability(model.id, 'REASONING', model.provider)` |
+| `isVisionModel(model)` | `catalog.hasCapability(model.id, 'IMAGE_RECOGNITION', model.provider)` |
+| `getThinkModelType(model)` | `catalog.getReasoningConfig(model.id, model.provider)` |

+This is a [Next.js](https://nextjs.org) project bootstrapped with [`create-next-app`](https://nextjs.org/docs/app/api-reference/cli/create-next-app).
+
+## Getting Started
+
+First, run the development server:
+
+```bash
+npm run dev
+# or
+yarn dev
+# or
+pnpm dev
+# or
+bun dev
+```
+
+Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.
+
+You can start editing the page by modifying `app/page.tsx`. The page auto-updates as you edit the file.
+
+This project uses [`next/font`](https://nextjs.org/docs/app/building-your-application/optimizing/fonts) to automatically optimize and load [Geist](https://vercel.com/font), a new font family for Vercel.
+
+## Learn More
+
+To learn more about Next.js, take a look at the following resources:
+
+- [Next.js Documentation](https://nextjs.org/docs) - learn about Next.js features and API.
+- [Learn Next.js](https://nextjs.org/learn) - an interactive Next.js tutorial.
+
+You can check out [the Next.js GitHub repository](https://github.com/vercel/next.js) - your feedback and contributions are welcome!
+
+## Deploy on Vercel
+
+The easiest way to deploy your Next.js app is to use the [Vercel Platform](https://vercel.com/new?utm_medium=default-template&filter=next.js&utm_source=create-next-app&utm_campaign=create-next-app-readme) from the creators of Next.js.
+
+Check out our [Next.js deployment documentation](https://nextjs.org/docs/app/building-your-application/deploying) for more details.

+
+## 🏗️ System Overview
+
+This directory provides type definitions for three main data management systems:
+
+### API System (`api/`)
+- **Purpose**: Type-safe IPC communication between Main and Renderer processes
+- **Features**: RESTful patterns, error handling, business entity definitions
+- **Usage**: Ensures type safety for all data API operations
+
+### Cache System (`cache/`)
+- **Purpose**: Type definitions for three-layer caching architecture
+- **Features**: Memory/shared/persist cache schemas, TTL support, hook integration
+- **Usage**: Type-safe caching operations across the application
+
+### Preference System (`preference/`)
+- **Purpose**: User configuration and settings management
+- **Features**: 158 configuration items, default values, nested key support
+- **Usage**: Type-safe preference access and synchronization
+
+## 📋 File Categories
+
+**Framework Infrastructure** - These are TypeScript type definitions that:
+- ✅ Exist only at compile time
+- ✅ Provide type safety and IntelliSense support
+- ✅ Define contracts between application layers
+- ✅ Enable static analysis and error detection
+
+## 📖 Usage Examples
+
+### API Types
+```typescript
+// Import API types
+import type { DataRequest, DataResponse, ApiSchemas } from '@shared/data/api'
+```
+
+### Cache Types
+```typescript
+// Import cache types
+import type { UseCacheKey, UseSharedCacheKey } from '@shared/data/cache'
+```
+
+### Preference Types
+```typescript
+// Import preference types
+import type { PreferenceKeyType, PreferenceDefaultScopeType } from '@shared/data/preference'
+```
+
+## 🔧 Development Guidelines
+
+### Adding Cache Types
+1. Add cache key to `cache/cacheSchemas.ts`
+2. Define value type in `cache/cacheValueTypes.ts`
+3. Update type mappings for type safety
+
+### Adding Preference Types
+1. Add preference key to `preference/preferenceSchemas.ts`
+2. Define default value and type
+3. Preference system automatically picks up new keys
+
+### Adding API Types
+1. Define business entities in `api/apiModels.ts`
+2. Add endpoint definitions to `api/apiSchemas.ts`
+3. Export types from `api/index.ts`
+
+### Best Practices
+- Use `import type` for type-only imports
+- Follow existing naming conventions
+- Document complex types with JSDoc
+- Maintain type safety across all imports
+
+## 🔗 Related Implementation
+
+### Main Process Services
+- `src/main/data/CacheService.ts` - Main process cache management
+- `src/main/data/PreferenceService.ts` - Preference management service
+- `src/main/data/DataApiService.ts` - Data API coordination service
+
+### Renderer Process Services
+- `src/renderer/src/data/CacheService.ts` - Renderer cache service
+- `src/renderer/src/data/PreferenceService.ts` - Renderer preference service
+- `src/renderer/src/data/DataApiService.ts` - Renderer API client
