# 项目指南技能(Project Guidelines Skill,示例) 这是一个特定项目的技能(Skill)示例。请将其用作你自定义项目的模板。 基于真实的生产应用:[Zenith](https://zenith.chat) - AI 驱动的客户发现平台。 --- ## 何时使用 (When to Use) 在处理该特定项目时参考此技能。项目技能包含: - 架构概览 (Architecture overview) - 文件结构 (File structure) - 代码模式 (Code patterns) - 测试要求 (Testing requirements) - 部署工作流 (Deployment workflow) --- ## 架构概览 (Architecture Overview) **技术栈 (Tech Stack):** - **前端 (Frontend)**:Next.js 15 (App Router), TypeScript, React - **后端 (Backend)**:FastAPI (Python), Pydantic 模型 - **数据库 (Database)**:Supabase (PostgreSQL) - **AI**:Claude API(支持工具调用与结构化输出) - **部署 (Deployment)**:Google Cloud Run - **测试 (Testing)**:Playwright (E2E), pytest (后端), React Testing Library **服务 (Services):** ``` ┌─────────────────────────────────────────────────────────────┐ │ Frontend │ │ Next.js 15 + TypeScript + TailwindCSS │ │ Deployed: Vercel / Cloud Run │ └─────────────────────────────────────────────────────────────┘ │ ▼ ┌─────────────────────────────────────────────────────────────┐ │ Backend │ │ FastAPI + Python 3.11 + Pydantic │ │ Deployed: Cloud Run │ └─────────────────────────────────────────────────────────────┘ │ ┌───────────────┼───────────────┐ ▼ ▼ ▼ ┌──────────┐ ┌──────────┐ ┌──────────┐ │ Supabase │ │ Claude │ │ Redis │ │ Database │ │ API │ │ Cache │ └──────────┘ └──────────┘ └──────────┘ ``` --- ## 文件结构 (File Structure) ``` project/ ├── frontend/ │ └── src/ │ ├── app/ # Next.js App Router 页面 │ │ ├── api/ # API 路由 │ │ ├── (auth)/ # 身份验证保护的路由 │ │ └── workspace/ # 主应用工作区 │ ├── components/ # React 组件 │ │ ├── ui/ # 基础 UI 组件 │ │ ├── forms/ # 表单组件 │ │ └── layouts/ # 布局组件 │ ├── hooks/ # 自定义 React 钩子 (Hooks) │ ├── lib/ # 工具库 │ ├── types/ # TypeScript 类型定义 │ └── config/ # 配置 │ ├── backend/ │ ├── routers/ # FastAPI 路由处理器 │ ├── models.py # Pydantic 模型 │ ├── main.py # FastAPI 应用入口 │ ├── auth_system.py # 身份验证系统 │ ├── database.py # 数据库操作 │ ├── services/ # 业务逻辑 │ └── tests/ # pytest 测试 │ ├── deploy/ # 部署配置 ├── docs/ # 文档 └── scripts/ # 工具脚本 ``` --- ## 代码模式 (Code Patterns) ### 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 { success: boolean data?: T error?: string } async function fetchApi( endpoint: string, options?: RequestInit ): Promise> { 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"} ) # 提取工具调用结果 tool_use = next( block for block in response.content if block.type == "tool_use" ) return AnalysisResult(**tool_use.input) ``` ### 自定义钩子 (React Hooks) ```typescript import { useState, useCallback } from 'react' interface UseApiState { data: T | null loading: boolean error: string | null } export function useApi( fetchFn: () => Promise> ) { const [state, setState] = useState>({ 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 (Testing Requirements) ### 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() expect(screen.getByRole('main')).toBeInTheDocument() }) it('handles session creation', async () => { render() fireEvent.click(screen.getByText('New Session')) expect(await screen.findByText('Session created')).toBeInTheDocument() }) }) ``` --- ## 部署工作流 (Deployment Workflow) ### 部署前自查清单 (Pre-Deployment Checklist) - [ ] 所有测试在本地通过 - [ ] `npm run build` 成功 (前端) - [ ] `poetry run pytest` 通过 (后端) - [ ] 无硬编码的秘钥 (Secrets) - [ ] 环境变量已记录文档 - [ ] 数据库迁移就绪 ### 部署命令 (Deployment Commands) ```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 (Environment Variables) ```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... ``` --- ## 核心规则 (Critical Rules) 1. 代码、注释或文档中**严禁使用 Emoji** 2. **不可变性 (Immutability)** - 永远不要直接改变对象或数组 3. **测试驱动开发 (TDD)** - 在实现之前编写测试 4. 最小 **80% 测试覆盖率** 5. **大量小文件** - 通常为 200-400 行,最多 800 行 6. 生产代码中**严禁使用 console.log** 7. 使用 try/catch 进行**妥善的错误处理** 8. 使用 Pydantic/Zod 进行**输入验证** --- ## 相关技能 (Related Skills) - `coding-standards.md` - 通用代码最佳实践 - `backend-patterns.md` - API 与数据库模式 - `frontend-patterns.md` - React 与 Next.js 模式 - `tdd-workflow/` - 测试驱动开发 (TDD) 方法论
