+# AGENTS.md - EmailBill Project Guidelines
+
+Full-stack budget tracking app with .NET 10 backend and Vue 3 frontend.
+
+## Project Structure
+
+```
+EmailBill/
+├── Common/           # Shared utilities and abstractions
+├── Entity/           # Database entities (FreeSql ORM)
+├── Repository/       # Data access layer
+├── Service/          # Business logic layer
+├── WebApi/           # ASP.NET Core Web API
+├── WebApi.Test/      # Backend tests (xUnit)
+└── Web/              # Vue 3 frontend (Vite + Vant UI)
+```
+
+## Build & Test Commands
+
+### Backend (.NET 10)
+```bash
+# Build and run
+dotnet build EmailBill.sln
+dotnet run --project WebApi/WebApi.csproj
+
+# Run all tests
+dotnet test WebApi.Test/WebApi.Test.csproj
+
+# Run single test class
+dotnet test --filter "FullyQualifiedName~BudgetStatsTest"
+
+# Run single test method
+dotnet test --filter "FullyQualifiedName~BudgetStatsTest.GetCategoryStats_月度_Test"
+
+# Clean
+dotnet clean EmailBill.sln
+```
+
+### Frontend (Vue 3)
+```bash
+cd Web
+
+# Setup and dev
+pnpm install
+pnpm dev
+
+# Build and preview
+pnpm build
+pnpm preview
+
+# Lint and format
+pnpm lint          # ESLint with auto-fix
+pnpm format        # Prettier formatting
+```
+
+## C# Code Style
+
+**Namespaces & Imports:**
+- File-scoped namespaces: `namespace Entity;`
+- Global usings in `Common/GlobalUsings.cs`
+- Sort using statements alphabetically
+
+**Naming:**
+- Classes/Methods: `PascalCase`
+- Interfaces: `IPascalCase`
+- Private fields: `_camelCase`
+- Parameters/locals: `camelCase`
+
+**Entities:**
+- Inherit from `BaseEntity`
+- Use `[Column]` attributes for FreeSql ORM
+- IDs via Snowflake: `YitIdHelper.NextId()`
+- Use XML docs (`///`) for public APIs
+- **Chinese comments for business logic** (per `.github/csharpe.prompt.md`)
+
+**Best Practices:**
+- Use modern C# syntax (records, pattern matching, nullable types)
+- Use `IDateTimeProvider` instead of `DateTime.Now` for testability
+- Avoid deep nesting, keep code flat and readable
+- Reuse utilities from `Common` project
+
+**Example:**
+```csharp
+namespace Entity;
+
+/// <summary>
+/// 实体基类
+/// </summary>
+public abstract class BaseEntity
+{
+    [Column(IsPrimary = true)]
+    public long Id { get; set; } = YitIdHelper.NextId();
+    
+    public DateTime CreateTime { get; set; } = DateTime.Now;
+}
+```
+
+## Vue/TypeScript Style
+
+**Component Structure:**
+```vue
+<template>
+  <van-config-provider :theme="theme">
+    <div class="component-name">
+      <!-- Content -->
+    </div>
+  </van-config-provider>
+</template>
+
+<script setup lang="ts">
+import { ref } from 'vue'
+import { useMessageStore } from '@/stores/message'
+
+const messageStore = useMessageStore()
+</script>
+
+<style scoped lang="scss">
+.component-name {
+  padding: 16px;
+}
+</style>
+```
+
+**Rules:**
+- Composition API with `<script setup lang="ts">`
+- Import order: Vue APIs → external libs → internal modules
+- Use `@/` alias for absolute imports, avoid `../../../`
+- Vant UI components: `<van-*>`
+- Pinia for state, Vue Router for navigation
+- SCSS with BEM naming, mobile-first design
+
+**ESLint Rules (see `Web/eslint.config.js`):**
+- 2-space indentation
+- Single quotes, no semicolons
+- `const` over `let`, no `var`
+- Always use `===` (strict equality)
+- `space-before-function-paren: 'always'`
+- Max 1 empty line between blocks
+- Vue: multi-word component names disabled
+
+**Prettier Rules (see `Web/.prettierrc.json`):**
+- Single quotes, no semicolons
+- Trailing commas: none
+- Print width: 100 chars
+
+## Testing
+
+**Backend (xUnit + NSubstitute + FluentAssertions):**
+```csharp
+public class BudgetStatsTest : BaseTest
+{
+    private readonly IBudgetRepository _repo = Substitute.For<IBudgetRepository>();
+    
+    [Fact]
+    public async Task GetCategoryStats_月度_Test()
+    {
+        // Arrange
+        _repo.GetAllAsync().Returns(testData);
+        
+        // Act
+        var result = await _service.GetCategoryStatsAsync(category, date);
+        
+        // Assert
+        result.Month.Limit.Should().Be(2500);
+    }
+}
+```
+- Arrange-Act-Assert pattern
+- Constructor injection for dependencies
+- Use Chinese test method names for domain clarity
+
+**Frontend:**
+- Vue Test Utils for components
+- axios-mock-adapter for API mocking
+
+## Development Workflow
+
+1. **Before committing backend:** `dotnet test`
+2. **Before committing frontend:** `pnpm lint && pnpm build`
+3. **Database migrations:** Use FreeSql (check `Repository/`)
+4. **API docs:** Scalar OpenAPI viewer
+
+## Environment
+
+**Required:**
+- .NET 10 SDK
+- Node.js 20.19+ or 22.12+
+- pnpm
+
+**Database:** SQLite (embedded)
+
+**Config:**
+- Backend: `appsettings.json`
+- Frontend: `.env.development` / `.env.production`
+
+## Critical Guidelines (from `.github/csharpe.prompt.md`)
+
+- 优先使用新C#语法 (Use modern C# syntax)
+- 优先使用中文注释 (Prefer Chinese comments for business logic)
+- 优先复用已有方法 (Reuse existing methods)
+- 不要深嵌套代码 (Avoid deep nesting)
+- 保持代码简洁易读 (Keep code clean and readable)
