## 代码模式

### API 响应格式 (FastAPI)

```python
from pydantic import BaseModel
from typing import Generic, TypeVar, Optional

T = TypeVar('T')

class ApiResponse(BaseModel, Generic[T]):
    success: bool
    data: Optional[T] = None
    error: Optional[str] = None

    @classmethod
    def ok(cls, data: T) -> "ApiResponse[T]":
        return cls(success=True, data=data)

    @classmethod
    def fail(cls, error: str) -> "ApiResponse[T]":
        return cls(success=False, error=error)
```

### 前端 API 调用 (TypeScript)

```typescript
interface ApiResponse<T> {
  success: boolean
  data?: T
  error?: string
}

async function fetchApi<T>(
  endpoint: string,
  options?: RequestInit
): Promise<ApiResponse<T>> {
  try {
    const response = await fetch(`/api${endpoint}`, {
      ...options,
      headers: {
        'Content-Type': 'application/json',
        ...options?.headers,
      },
    })

    if (!response.ok) {
      return { success: false, error: `HTTP ${response.status}` }
    }

    return await response.json()
  } catch (error) {
    return { success: false, error: String(error) }
  }
}
```

### Claude AI 集成 (结构化输出)

```python
from anthropic import Anthropic
from pydantic import BaseModel

class AnalysisResult(BaseModel):
    summary: str
    key_points: list[str]
    confidence: float

async def analyze_with_claude(content: str) -> AnalysisResult:
    client = Anthropic()

    response = client.messages.create(
        model="claude-sonnet-4-5-20250514",
        max_tokens=1024,
        messages=[{"role": "user", "content": content}],
        tools=[{
            "name": "provide_analysis",
            "description": "Provide structured analysis",
            "input_schema": AnalysisResult.model_json_schema()
        }],
        tool_choice={"type": "tool", "name": "provide_analysis"}
    )

    # 提取工具使用(tool_use)结果
    tool_use = next(
        block for block in response.content
        if block.type == "tool_use"
    )

    return AnalysisResult(**tool_use.input)
```

### 自定义 Hooks (React)

```typescript
import { useState, useCallback } from 'react'

interface UseApiState<T> {
  data: T | null
  loading: boolean
  error: string | null
}

export function useApi<T>(
  fetchFn: () => Promise<ApiResponse<T>>
) {
  const [state, setState] = useState<UseApiState<T>>({
    data: null,
    loading: false,
    error: null,
  })

  const execute = useCallback(async () => {
    setState(prev => ({ ...prev, loading: true, error: null }))

    const result = await fetchFn()

    if (result.success) {
      setState({ data: result.data!, loading: false, error: null })
    } else {
      setState({ data: null, loading: false, error: result.error! })
    }
  }, [fetchFn])

  return { ...state, execute }
}
```

---

## 测试要求

### 后端 (pytest)

```bash
# 运行所有测试
poetry run pytest tests/

# 运行并生成覆盖率报告
poetry run pytest tests/ --cov=. --cov-report=html

# 运行特定测试文件
poetry run pytest tests/test_auth.py -v
```

**测试结构:**
```python
import pytest
from httpx import AsyncClient
from main import app

@pytest.fixture
async def client():
    async with AsyncClient(app=app, base_url="http://test") as ac:
        yield ac

@pytest.mark.asyncio
async def test_health_check(client: AsyncClient):
    response = await client.get("/health")
    assert response.status_code == 200
    assert response.json()["status"] == "healthy"
```

### 前端 (React Testing Library)

```bash
# 运行测试
npm run test

# 运行并生成覆盖率报告
npm run test -- --coverage

# 运行 E2E 测试
npm run test:e2e
```

**测试结构:**
```typescript
import { render, screen, fireEvent } from '@testing-library/react'
import { WorkspacePanel } from './WorkspacePanel'

describe('WorkspacePanel', () => {
  it('renders workspace correctly', () => {
    render(<WorkspacePanel />)
    expect(screen.getByRole('main')).toBeInTheDocument()
  })

  it('handles session creation', async () => {
    render(<WorkspacePanel />)
    fireEvent.click(screen.getByText('New Session'))
    expect(await screen.findByText('Session created')).toBeInTheDocument()
  })
})
```

## 部署工作流

### 部署前检查清单

- [ ] 所有测试均在本地通过
- [ ] `npm run build` 成功(前端)
- [ ] `poetry run pytest` 通过(后端)
- [ ] 无硬编码密钥
- [ ] 环境变量已记录
- [ ] 数据库迁移已就绪

### 部署命令

```bash
# 构建并部署前端
cd frontend && npm run build
gcloud run deploy frontend --source .

# 构建并部署后端
cd backend
gcloud run deploy backend --source .
```

### 环境变量

```bash
# 前端 (.env.local)
NEXT_PUBLIC_API_URL=https://api.example.com
NEXT_PUBLIC_SUPABASE_URL=https://xxx.supabase.co
NEXT_PUBLIC_SUPABASE_ANON_KEY=eyJ...

# 后端 (.env)
DATABASE_URL=postgresql://...
ANTHROPIC_API_KEY=sk-ant-...
SUPABASE_URL=https://xxx.supabase.co
SUPABASE_KEY=eyJ...
```

## 关键规则

1. **不得使用表情符号**(No emojis):在代码、注释或文档中不得使用表情符号
2. **不可变性**(Immutability):永远不要直接修改对象或数组
3. **TDD**:在实现之前编写测试
4. **最低 80% 覆盖率**
5. **采用多个小文件**:通常 200-400 行,最多 800 行
6. **不得使用 console.log**:生产代码中不得使用 console.log
7. **正确的错误处理**:使用 try/catch 进行错误处理
8. **输入验证**:使用 Pydantic/Zod 进行输入验证
