## 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
