+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## 项目概述
+
+Game Group V2 — 游戏组队管理平台。用户创建/加入群组，组队开黑，管理游戏库。
+
+## 开发命令
+
+```bash
+# 前端开发（默认连接 localhost:8090 的 PocketBase）
+cd frontend && npm run dev
+
+# 前端开发环境（连接远程后端 192.168.1.14:8711，端口 7033）
+cd frontend && npm run dev:dev
+
+# 前端 UAT 环境（端口 7034）
+cd frontend && npm run dev:uat
+
+# 构建前端
+cd frontend && npm run build
+
+# 启动后端（PocketBase，端口 8711）
+cd backend && docker-compose up -d
+
+# 部署脚本（根目录）
+./deploy-backend.sh   # 部署后端
+./deploy-dev.sh       # 部署 Dev 前端
+./deploy-uat.sh       # 部署 UAT 前端
+./stop-all.sh         # 停止所有服务
+```
+
+## 技术栈
+
+- **后端**: PocketBase 0.22.4 (Docker, `ghcr.io/muchobien/pocketbase`) — 无自定义 JS hooks，业务逻辑全在前端
+- **前端**: Vue 3 + TypeScript + Pinia + Element Plus + Tailwind CSS + Vite
+- **API 通信**: PocketBase JS SDK (`pocketbase` npm 包)，cookie 认证
+- **实时通信**: PocketBase realtime subscriptions
+
+## 架构
+
+### 前端目录结构 (`frontend/src/`)
+
+- **`api/`** — 每个领域一个文件（`users.ts`, `groups.ts`, `sessions.ts`, `invitations.ts`, `games.ts`），封装 PocketBase CRUD 和过滤逻辑。`pocketbase.ts` 初始化客户端并导出认证工具函数
+- **`stores/`** — Pinia stores（`user`, `group`, `team`, `notification`），组合式 API 风格（`defineStore('name', () => {...})`）
+- **`composables/useRealtime.ts`** — 统一管理 PocketBase 实时订阅，组件卸载时自动清理
+- **`views/`** — 页面级组件，路由懒加载
+- **`components/`** — 按领域分子目录：`common/`, `game/`, `group/`, `layout/`, `team/`
+- **`types/index.ts`** — 所有 TypeScript 接口和类型定义集中在一个文件
+
+### 数据模型（PocketBase Collections）
+
+- **users** — 用户，含状态（idle/working/in_team/away）、工作时间设定、积分
+- **groups** — 群组，owner + members 关系，支持审核加入（requireApproval）
+- **team_sessions** — 临时组队，关联 sourceGroup，状态流转：recruiting → playing → finished/dissolved
+- **invitations** — 组队邀请，from/to 用户，pending/accepted/rejected
+- **games** — 游戏库，归属 group，含平台、标签、封面
+- **game_comments** / **game_favorites** — 游戏评论和收藏
+- **join_requests** — 入群申请，pending/approved/rejected
+
+### 关键模式
+
+- **Vite 代理**: 开发时 `/api` 代理到 PocketBase，路径重写去掉 `/api` 前缀（`vite.config.ts`）
+- **认证流程**: `pocketbase.ts` → cookie 持久化 → 路由守卫检查 `isAuthenticated()` → 未登录跳转 `/login`
+- **实时订阅**: 通过 `useRealtime` composable 和 `subscribe*` 函数订阅 PocketBase 变更事件，各 store 自行刷新数据
+- **样式系统**: 自定义 CSS 变量（`design.css`，`--gg-*` 前缀）+ Tailwind + Element Plus，主题色为绿色系
+
+### 后端
+
+- PocketBase 数据迁移在 `backend/pb_migrations/`，由管理面板操作自动生成
+- `backend/pb_hooks/main.js` 为占位文件，当前镜像不支持 JS VM
+- 所有业务逻辑（如入群审批、组队邀请）在前端 API 层实现
+
+## 环境配置
+
+前端通过 `.env` 文件配置：
+- `VITE_PB_URL` — PocketBase 地址（默认 `window.location.origin`）
+- `VITE_PORT` — 开发服务器端口
