+# TradeMate 产品策略：Agent Skills + 浏览器插件
+
+## 一、市场背景
+
+### 1.1 AI Agent Skills 生态（2026）
+
+SKILL.md 开放标准已被 20+ 工具原生支持，包括 Cursor、Claude Code、OpenAI Codex CLI、OpenCode、Gemini CLI、GitHub Copilot、VS Code 等。这意味着**一份 SKILL.md 文件可以分发到几乎所有主流 AI 编程工具**。
+
+商业化现状：
+- 头部 skill 月收入 $500-$3,000，中位数 < $50/月
+- 定价 $5-$25 一次性购买为主，订阅制尚在试验
+- 平台抽成：Agensi 等第三方市场抽 20%
+
+### 1.2 外贸工具浏览器插件生态
+
+Chrome Web Store 上已有数十款外贸工具插件：
+- **Topease** — AI 客户开发、邮箱提取、LinkedIn 线索
+- **瞬悉** — 商品采集、店铺分析、AI 生成标题/开发信
+- **生意助手** — 国际站选品/搬品
+- **外贸侠** — 询盘分析、访客分析、聊天记录分析
+- **信风AI** — 海关数据、社媒拓客、AI 电话
+
+共同特征：
+- 全部为 Chrome 插件
+- 核心卖点：获客 + 运营提效
+- 定价：几十到几百人民币/月
+- 模式：免费版限制用量 → 付费订阅
+
+## 二、TradeMate 的定位
+
+TradeMate 的核心优势：
+- **已有完整后端 API**：翻译、客户管理、营销生成、客户发现、报价单等
+- **多 AI 提供商**：商汤、NVIDIA、阿里翻译，不依赖单一厂商
+- **轻量级**：无需部署，已有 Vue 3 前端工作台
+
+定位差异化：**不做阿里国际站垂直插件，做通用的外贸 AI 工作台**，覆盖从获客到成交的全链路。
+
+## 三、三产品线架构

+
+三者关系：
+- **共享同一后端 API**，不重复开发逻辑
+- **项目本身**是全功能工作台
+- **Agent Skills** 是给 AI 编程助手用的轻量能力包
+- **浏览器插件**是非技术用户最顺手的入口
+- 用户可以从任一入口开始使用，随需求升级自然流向其他产品
+
+## 四、Agent Skills 规划
+
+### 4.1 Skill 列表
+
+| Skill 名称 | 功能 | 调用后端 API |
+|-----------|------|-------------|
+| `translate-reply` | AI 翻译 + 智能回复生成 | `POST /api/v1/translate`, `POST /api/v1/translate/reply` |
+| `customer-discovery` | Google 搜索客户 + 信息提取 | `POST /api/v1/discovery/search` |
+| `marketing-content` | 营销文案/关键词生成 | `POST /api/v1/marketing/generate`, `POST /api/v1/marketing/keywords` |
+| `quotation-gen` | 从询盘生成报价单 | `POST /api/v1/quotations` |
+| `followup-scan` | 沉默客户扫描 + 提醒 | `POST /api/v1/followup/scan` |
+
+### 4.2 分发策略
+
+1. **免费发布**到 Agensi.io、cursor.directory、skills.sh
+2. 内置在项目 `.opencode/skills/` 中，项目自身用 OpenCode 开发时可直接使用
+3. 每个 SKILL.md 描述清晰的目标、输入、输出，独立可用
+
+### 4.3 格式标准
+
+遵循 SKILL.md 标准格式：
+- `name` — 技能名称
+- `description` — 一句话说明
+- `trigger` — 触发关键词
+- `steps` — 执行步骤
+- `api_endpoints` — 调用的后端接口（需用户自行配置 BASE_URL 和 API Key）
+
+## 五、浏览器插件规划
+
+### 5.1 功能模块
+
+| 模块 | 功能 | 对应后端 |
+|------|------|---------|
+| AI 翻译 | 输入文本自动翻译、划词翻译 | `POST /api/v1/translate` |
+| 智能回复 | 根据客户询盘生成回复建议 | `POST /api/v1/translate/reply` |
+| 客户发现 | 输入关键词搜索目标客户 | `POST /api/v1/discovery/search` |
+| 营销文案 | 生成营销内容/关键词 | `POST /api/v1/marketing/generate` |
+| 快速报价 | 从询盘内容生成报价单 | `POST /api/v1/quotations` |
+
+### 5.2 技术架构
+
+```

+```
+
+### 5.3 统一积分体系
+
+三产品线共享同一套积分系统（后端已实现）：
+
+```
+                     ┌─────────────────────────┐
+                     │    TradeMate 后端         │
+                     │    CreditService          │
+                     │    ┌──────────────────┐  │
+                     │    │  积分池             │  │
+                     │    │  Free: 30 一次性    │  │
+                     │    │  Starter: 200/月    │  │
+                     │    │  Pro: 1000/月       │  │
+                     │    │  Enterprise: 2500/月│  │
+                     │    └──────────────────┘  │
+                     └─────────────────────────┘
+                              │
+        ┌─────────────────────┼─────────────────────┐
+        │                     │                     │
+  网页工作台            浏览器插件              Agent Skills
+  (消耗积分)            (消耗积分)             (需要有效 Token)
+```
+
+**关键设计**：
+- 积分（credits）是唯一货币，跨三产品线通用
+- 用户在一个地方订阅，所有入口自动升级
+- 后端已有 `CreditService` + `SubscriptionPlan` + `CreditPackage` 完整体系
+- 浏览器插件通过 API 自动获取当前用户积分余额和套餐信息
+
+**消耗标准**（后端已定义 `DEFAULT_CONSUMPTION_RATES`）：
+
+| 功能 | 消耗积分 | 说明 |
+|------|---------|------|
+| 翻译 | 1/1000 字符 | 每日前 1000 字符免费 |
+| 客户搜索 (lead_search) | 10 | 单次 Google 搜索 + 结果提取 |
+| 客户分析 (company_analysis) | 5 | 单个网站信息提取 |
+| 营销生成 (marketing_content) | 5 | 单次 AI 文案生成 |
+| 智能回复 (reply_suggest) | 2 | 单次回复建议生成 |
+| 竞品分析 | 10 | 单次竞品对比 |
+| 报价单 | 2 | 从询盘生成报价单 |
+| AI 对话 | 1/10 条 | AI 数字员工对话 |
+
+### 5.4 认证方案
+
+- 使用 JWT Token 认证，与项目本身共享同一套用户体系
+- 首次使用输入 API 地址和 Token（或扫码登录）
+- Token 存储在 `chrome.storage.local`
+
+### 5.5 定价模型
+
+#### 5.5.1 月度订阅
+
+| 层级 | 月付 | 年付 (折合/月) | 月积分 | 核心权益 |
+|------|------|---------------|--------|---------|
+| **Free** | ¥0 | — | 30 一次性 + 1000字/天免费翻译 | 体验客户搜索 x3 + 基本翻译 |
+| **Starter** | ¥9.9 | ¥99 (¥8.25) | 200 | 解除日限，含翻译/回复/发现/营销/报价 |
+| **Professional** | ¥49 | ¥499 (¥41.6) | 1000 | AI 数字员工 + 团队 (3人) + 优先支持 |
+| **Enterprise** | ¥99 | ¥999 (¥83.3) | 2500 | 不限团队 + API 调用 + SLA 保障 |
+
+**Free → Starter 转化逻辑**：
+- 新用户一次性赠送 30 积分 ≈ 3 次客户搜索 或 6 次营销生成
+- 用完即触发升级提示，不走"每日限制"——集中的体验窗口比分散的每日限额更能驱动转化
+- 每日 1000 字免费翻译作为持续留存钩子，不让用户完全流失
+
+**Starter ¥9.9/月**：
+- 200 积分/月 ≈ 20 次客户搜索 或 40 次营销生成
+- 足够轻度 SOHO 用户日常使用 20 天
+- 不是"无限量"（后端 AI 调用有成本），但大部分用户用不完 200 积分
+- 积分的**滚动/过期策略**：未用完的积分最多累积到月配额的 2x，鼓励持续付费
+
+**Professional ¥49/月** — 利润引擎：
+- AI 数字员工（AgentOrchestrator）是差异化的核心功能
+- 1000 积分 ≈ 100 次客户搜索，覆盖重度用户
+- 团队协作（3 人）增加粘性和替换成本
+
+**Enterprise ¥99/月** — 高价值客户：
+- 不限团队成员数
+- 开放 API 调用权限（用于自定义集成）
+- SLA 保障
+
+#### 5.5.2 一次性积分包（低门槛入门付费）
+
+为"偶尔用用"的用户设计，降低首次付费心理门槛：
+
+| 积分包 | 价格 | 折合单价 | 有效期 |
+|-------|------|---------|-------|
+| 50 积分 | ¥2.9 | 0.058/积分 | 30 天 |
+| 200 积分 | ¥9.9 | 0.050/积分 | 90 天 |
+| 600 积分 | ¥24.9 | 0.042/积分 | 180 天 |
+
+积分包的作用：
+- 用完 Free 额度的用户只需花 **¥2.9** 就能继续用，而不是直接跳到 ¥9.9/月
+- ¥2.9 的支付摩擦远低于 ¥9.9，付费转化率会显著提升
+- 多次购买积分包后，用户自然过渡到订阅（"我每个月都花 ¥9.9 买积分包，不如直接订阅"）
+
+#### 5.5.3 三产品线统一定价映射
+
+```
+                  Free          Starter (¥9.9)    Professional (¥49)    Enterprise (¥99)
+网页工作台         ✓             ✓                  ✓                    ✓
+浏览器插件         ✓             ✓                  ✓                    ✓
+Agent Skills      (需自备Key)   (需自备Key)         含 Token            含 Token
+```
+
+用户只需订阅一次，所有入口通用。后端判断权限的依据是**当前用户的积分余额和订阅计划**，而不是产品入口。
+
+### 5.6 付费转化设计（升级触发器）
+
+定价只是桌子，付费转化才是把客人请进来坐下。以下是每个触点的设计：
+
+#### 5.6.1 Free 用完积分
+
+```
+触发时机：用户发起请求，后端返回 402 Payment Required
+          { "detail": "次数不足 (剩余 0.0, 需要 10)" }
+
+插件显示：
+┌──────────────────────────────────────────────┐
+│  ⚡ 体验积分已用完                             │
+│  30 次体验积分已用完，本次搜索需要 10 积分。    │
+│                                              │
+│  [买 50 积分 ¥2.9]  [订阅 Starter ¥9.9/月]   │
+│  或者下次再说                                 │
+└──────────────────────────────────────────────┘
+```
+
+#### 5.6.2 功能灰化预览
+
+```
+AI 数字员工 Tab 始终可见，但 Professional 以下层级显示：
+
+┌──────────────────────────────────────────────┐
+│  🔒 AI 数字员工                                │
+│  自动搜索客户 → 分析公司 → 生成开发信 → 保存 CRM │
+│  全流程自动化，每天可处理 10+ 潜在客户           │
+│                                              │
+│  [升级 Professional ¥49/月 解锁]              │
+└──────────────────────────────────────────────┘
+```
+
+#### 5.6.3 活跃度推送
+
+首次使用后第 3 天：
+
+```
+通知标题：TradeMate 还够用吗？
+内容：你已使用了 12 次翻译、2 次客户搜索
+      升级 Starter 可解除所有限制，仅 ¥9.9/月
+```
+
+#### 5.6.4 积分仪表盘
+
+Footer 始终显示：
+
+```
+剩余 15 积分 · 可用 1 次搜索 · 升级 ↑
+```
+
+点击"升级"弹出价格对比卡片——**即时可见可用性**是转化核心驱动力。
+
+#### 5.6.5 限时 Pro 试用
+
+在新用户注册后，自动赠送 3 天 Pro 体验（300 积分 + 完整功能）：
+- 体验结束后恢复到 Free 层
+- 体验期间展示："还剩 2 天 Pro 体验 · 到期自动降级"
+- 到期前 24 小时推送转化："Pro 体验即将结束，订阅仅 ¥9.9/月"
+
+## 六、实施路线图
+
+### Phase 1：文档 + Agent Skills（已完成）
+- [x] 产品策略文档（本文档）
+- [x] 创建 `.opencode/skills/` 目录
+- [x] 完成 `translate-reply` SKILL.md
+- [x] 完成 `customer-discovery` SKILL.md
+- [x] 完成 `marketing-content` SKILL.md
+
+### Phase 2：浏览器插件骨架（已完成）
+- [x] 创建 `browser-extension/` 项目
+- [x] 完成 manifest.json 配置
+- [x] 完成 popup 基础 UI
+- [x] 对接翻译 API
+- [x] 对接客户发现 API
+- [x] 对接营销生成 API
+- [x] 积分余额展示 + 配额不足升级引导
+
+### Phase 3：上架与运营（持续）
+- [ ] 定价模型数据库化：配置 SubscriptionPlan + CreditPackage 种子数据
+- [ ] 插件端积分展示 + 升级引导 UI 绑定实际 API 响应
+- [ ] 发布 SKILL.md 到 Agensi / cursor.directory
+- [ ] 发布 Chrome 插件到 Chrome Web Store
+- [ ] 配置 Stripe/PayPal 订阅支付（复用后端现有支付系统）
+
+## 七、兼容性保证
+
+1. **后端无侵入** — Skills 和插件调用已有 API 端点，不改动现有路由
+2. **前端无侵入** — 浏览器插件是独立项目，不修改 user-frontend/admin-frontend
+3. **数据共享** — 同一用户在不同入口产生的数据互通（共用同一数据库）
+4. **可单独部署** — 后端可独立运行，Skills 和插件只是客户端
+5. **积分互通** — 所有入口共享 `CreditService`，消费记录统一记录在 `credit_consumptions` 表
+6. **套餐配置化** — `SubscriptionPlan` 和 `CreditPackage` 存储在 DB 中，不硬编码在前端，管理员可随时调整价格和配额
