# Android项目全局上下文文档
## 1. 项目概况
语言：Kotlin、少量 Java 本地库代码
架构：Jetpack Compose 单 Activity UI，未形成标准 MVVM；当前主要通过 Composable 局部状态、StateFlow 全局 Manager、SharedPreferences 持久化驱动界面
技术栈：AndroidX、Jetpack Compose、Material3、Haze 毛玻璃、OkHttp、Gson、ZXing、Google Play Services Location、LeakCanary、Android Instrumentation Test
Gradle/SDK版本：Android Gradle Plugin 8.9.1，Kotlin 2.1.0，Compose BOM 2024.10.00，compileSdk 36，targetSdk 36，minSdk 33，Java/Kotlin JVM 1.8
项目作用：智能家居控制面板应用，提供登录、房间管理、设备控制展示、场景、自动化、设置、背景壁纸、多语言、天气展示，并预留 CAN/MQTT 设备柜通信能力
模块：settings.gradle.kts 当前仅 include :app；仓库内存在 blurview Android Library 源码和 test/BlurView-master 示例/测试目录，但未接入当前主工程构建
## 2. 包结构与模块职责
com.example.smarthome：应用入口层
包含 SmartHomeApp、MainActivity、MainActivityCompose、MainActivityHaze、MainActivityAlternative。生产入口是 MainActivity，负责初始化语言/用户管理器、隐藏系统栏、挂载 activity_main.xml 中的 ComposeView 并渲染 AppRoot。
com.example.smarthome.data：数据、状态和服务层
UserManager 管理登录状态、用户信息、手机号验证码模拟登录和用户资料持久化。
LanguageManager 管理多语言枚举、翻译字典、语言持久化和切换语言后的应用重启。
BackgroundManager 管理背景壁纸列表、当前背景 StateFlow 和持久化。
WeatherService 使用定位、HTTP 天气接口、缓存和模拟兜底获取天气。
DeviceManager 聚合 MQTT 与 CAN 服务，向 UI 暴露设备控制统一入口。
MqttService.kt 定义 MQTT 常量、实体、接口和模拟实现。
CanService.kt 定义 CAN 常量、命令、实体、接口和模拟实现。
com.example.smarthome.ui：Compose UI 层
MainScaffold 是主界面核心，承载控制台、房间内容、设备卡片、空调/灯光/图表、顶部栏、导航相关组件。
LoginScreen、PhoneLoginScreen 提供微信扫码模拟登录和手机号验证码登录。
SettingsScreen 提供设置、语言、背景、房间管理、退出登录。
RoomDialog 提供添加/编辑/删除房间弹窗。
SceneScreen 管理场景开关。
AutomationScreen 管理自动化列表增删改状态。
SecurityScreen 管理安防状态展示与本地开关。
StatisticsScreen 展示静态能耗统计。
SmartHomeScreen、HomeScreen、Neumorph*、LiquidIndicator 是备用/实验性界面或通用视觉组件。
Previews 提供多尺寸 Compose 预览。
com.example.smarthome.ui.theme：主题层
SmartHomeTheme 使用 Material3 darkColorScheme，当前为固定深色主题。
eightbitlab.com.blurview：本地 BlurView 库源码
包含 BlurView、BlurController、PreDrawBlurController、RenderScriptBlur、RenderNodeBlurController 等传统 View 毛玻璃实现；当前未被 :app 依赖。
## 3. 分层与数据流
启动流程：MainActivity.onCreate -> LanguageManager.init(context) -> UserManager.init(context) -> 隐藏状态栏/导航栏 -> ComposeView.setContent -> SmartHomeTheme -> AppRoot。
登录数据流：AppRoot collect UserManager.isLoggedIn。未登录显示 LoginScreen；微信模拟登录调用 UserManager.login，手机号登录调用 UserManager.sendVerifyCode、verifyCode、loginWithPhone；登录成功后 UserManager.isLoggedIn 变为 true，自动切换到 MainContent。
主界面数据流：MainContent 从 smart_home_prefs.rooms 加载房间列表，使用 Compose remember/mutableStateOf 保存 selectedRoom、selectedNavItem、rooms，通过回调传给 MainScaffold。房间增删改由 saveRooms 写入 SharedPreferences 后更新 Compose 状态。
导航数据流：MainScaffold 根据 selectedNavItem 分发页面：0 控制台、1 场景、2 自动化、3 设置。SecurityScreen、StatisticsScreen 和部分导航组件已存在，但当前主 switch 未接入对应页面。
控制台数据流：DashboardContent -> RoomSelector -> RoomContent。总览房间显示环境、安全健康、模式、灯光、所有设备；具体房间显示空调卡、状态图、灯光行、设备网格。多数设备/图表数据为 UI 局部状态或静态模拟数据。
设置数据流：SettingsContent -> SettingsContentList。语言通过 LanguageManager.currentLanguage collect，切换语言写入 language_prefs 并重启应用；背景通过 BackgroundManager.selectedBackground collect，切换背景写入 background_prefs；退出登录调用 UserManager.logout。
场景/自动化/安防数据流：SceneScreen 使用 SharedPreferences("scenes") 保存场景激活状态；AutomationScreen 使用 SharedPreferences("automations").automation_list 和 Gson 保存自动化列表；SecurityScreen 使用 smart_home_prefs.security_armed 保存安防开关。
设备通信数据流：UI 可通过 rememberDeviceManager() 获取 DeviceManager。DeviceManager.initialize 打开 CAN 串口，并在 MQTT 参数完整时初始化/连接 MQTT；业务方法调用 ICanService 发送开门、上电、LED、查询等命令；CAN 回调进入 handleCanResponse，必要时触发后续 CAN 查询或 MQTT 上报。当前 CAN/MQTT 均是模拟实现，真实客户端代码以 TODO 注释保留。
线程规则：Compose 状态更新主要在主线程组合环境内完成；网络天气请求在 WeatherService.getWeather 中通过 withContext(Dispatchers.IO) 执行；DeviceManager 使用 CoroutineScope(SupervisorJob() + Dispatchers.IO) 初始化 CAN/MQTT；CAN/MQTT 的 MutableStateFlow 可跨线程更新，但新增真实硬件/网络回调时需注意线程切换和生命周期释放。
## 4. 核心基类
当前项目没有自定义 BaseActivity、BaseFragment、BaseViewModel、Repository 基类。
Activity 基类使用系统/AndroidX 类：MainActivity、MainActivityCompose、MainActivityHaze 继承 ComponentActivity；MainActivityAlternative 继承 AppCompatActivity。
全局状态封装以 singleton object/class manager 为主：UserManager、LanguageManager、BackgroundManager、WeatherService、DeviceManager、MqttServiceImpl、CanServiceImpl。
## 5. 现有通用封装
网络：WeatherService 使用 OkHttp 访问 7timer、wttr.in、ip-api；LoginScreen 使用 HttpURLConnection 预留微信扫码登录接口；MqttServiceImpl 预留真实 MQTT 客户端接入点但当前只模拟连接和发布日志。
本地存储：广泛使用 SharedPreferences，包括 user_prefs、users_database、language_prefs、background_prefs、smart_home_prefs、scenes、automations、mqtt_prefs。
状态封装：使用 MutableStateFlow/StateFlow 暴露登录、用户、语言、背景、MQTT 连接、CAN 连接、最后 CAN 响应、当前设备操作等状态。
工具方法：tr(key) 多语言快捷函数；rememberSelectedBackground()、rememberDeviceManager()、rememberMqttConnectionState()、rememberCanConnectionState() Compose 便捷函数；Context.getMqttService()、Context.getCanService() 扩展；generateQRCode 使用 ZXing 生成二维码；Context.findActivity() 用于从 Context 查找 Activity。
UI 通用组件：BackgroundSelector、LanguageSelectDialog、EditRoomsDialog、AddRoomDialog、CustomSwitch、GradientButton、CustomSlider、LightSlider、BlurGlassCard、FloatingBottomNav、SideNavRail、NeumorphButton、LiquidIndicator 等。
## 6. 开发约束
- 最小改动，禁止随意重构稳定代码
- 遵守分层架构，不跨层调用
- 优先复用现有代码，不重复造轮子
- 沿用项目现有第三方方案
- 当前没有标准 ViewModel/Repository 层；新增功能应优先沿用现有 Manager + StateFlow + Compose 状态方式，除非明确要求架构升级
- 修改房间、登录、语言、背景等功能时，应复用现有 SharedPreferences key 和 Manager，不要引入新的重复存储
- 修改设备通信时，应通过 DeviceManager、IMqttService、ICanService 接口扩展，不要让 UI 直接拼 CAN 帧或 MQTT topic
- 修改 UI 时优先复用 MainScaffold.kt、SettingsScreen.kt、RoomDialog.kt 中已有组件和视觉风格
- 注意 SecurityScreen、StatisticsScreen 当前未接入生产导航 switch，接入前需确认导航索引设计
- 注意 UiAdaptationTest 引用了当前源码中不存在的 ControlPanel，测试维护前需先确认目标组件
## 7. 核心实体与全局常量
核心实体：
UserManager.UserInfo：用户 ID、手机号、昵称、头像、注册/登录时间、性别、生日、邮箱、地址。
BackgroundOption：背景 id、名称、资源、缩略图、描述、是否深色。
WeatherInfo：温度、天气、湿度、空气质量、AQI、城市。
DoorInfo：格口/柜子/设备状态、接口、电压、SN、PVD、PRO、MFG、电量、维修状态。
DeviceEvent：借还/丢失等设备事件上报字段。
CanMessage、CanResponse：CAN 命令和响应数据。
Scene：场景 id、名称、描述、图标、渐变、激活状态。
Automation：自动化 id、名称、触发条件、动作、启用状态。
SecurityEvent：安全事件标题、时间、类型、描述。
Device：UI 设备卡片名称、副标题、图标、开关状态。
ScanStatusResult、ScanStatus：扫码登录状态。
全局常量：
LoginConfig：BASE_URL、GET_QR_CODE、CHECK_STATUS、POLL_INTERVAL、QR_EXPIRE_TIME、USE_MOCK。
MqttConstants：MQTT host、API host、端口、发布/订阅 topic 前后缀、QoS。
CanConstants：默认串口 /dev/ttyS4、波特率 115200、CAN 帧头/长度/帧尾、门开关状态。
CanCommands：LON、LOF、LST、PON、POF、RON、GON、AOF、PVD、MFG、PRO、DSN、CON、1VER、1LEN、1MD5、1MDE。
OperationType：借、还、维修、批量出入柜、格口上断电、灯光、设备信息、固件版本、开门、异常检测等操作码。
LanguageManager.Language：中文、英文、韩文、日文、俄文。
Mode：HOME、AWAY、FUN、MOVIE。
## 8. 协作约定
生成本文档后，后续我只提供待修改局部代码，不再发送完整工程。所有修改基于这份上下文；信息不足、架构冲突请主动提问，不要自行猜测。回复仅输出改动代码+简短说明。

# My Coffee 瑞幸咖啡下单助手
## 前置条件
**必需 MCP Server**: `my-coffee`
优先使用名为 `my-coffee` 的 MCP server；若当前智能体暴露的是同一瑞幸订单 MCP 的其它别名，以实际可用 server 名为准。
**MCP 配置**:
```json
{
"my-coffee": {
"type": "streamableHttp",
"url": "https://gwmcp.lkcoffee.com/order/user/mcp",
"headers": {
"Authorization": "Bearer ${LUCKIN_MCP_TOKEN}"
}
}
}
```
**安全说明**:
- `LUCKIN_MCP_TOKEN` 读取优先级：环境变量 `LUCKIN_MCP_TOKEN` > 当前对话用户明确提供的 token > 本地文件 `~/.my-coffee/LUCKIN_MCP_TOKEN`（仅在用户明确同意记录后可使用）。
- 如果用户在当前或历史消息里发过完整 token，应先尝试该 token，不要直接让用户重新登录平台获取。
- 用户发送 token 时必须先询问是否记录到 `~/.my-coffee/LUCKIN_MCP_TOKEN` 供后续对话复用；只有用户明确同意才可写入，禁止静默保存。
- 写入 token 前确保目录存在（`mkdir -p ~/.my-coffee`）；写入后建议限制权限（如 `chmod 600 ~/.my-coffee/LUCKIN_MCP_TOKEN`）。
- 用户要求撤销保存时，删除本地 token 文件 `~/.my-coffee/LUCKIN_MCP_TOKEN`，并明确告知“后续将不再从本地文件复用 token”。
- 除非用户明确要求 MCP 配置，否则不要输出 Authorization token。
- 真实 MCP 请求必须使用完整 token：优先 `Authorization: Bearer ${LUCKIN_MCP_TOKEN}`；若用户已提供 token，则使用用户提供的完整原文。
- 禁止执行 `Bearer ***`、`Bearer xxx…yyy`、`Bearer <token>` 等占位 Authorization；如果没有环境变量且用户也没提供 token，只提示用户配置或提供 `LUCKIN_MCP_TOKEN` 后重试。
- 首次调用某 MCP 工具前，或不确定参数时，先读取对应工具 descriptor/schema；本文参数只是快速参考，实际以 schema 为准。
- 创建订单可能生成真实支付二维码，回复只保留必要的订单和支付信息。
## MCP 调用模式
优先调用当前智能体已配置的 `my-coffee` MCP 工具。若当前智能体没有配置 MCP server，但可拿到有效 token（环境变量 / 用户在对话中提供 / 本地文件 `~/.my-coffee/LUCKIN_MCP_TOKEN`），使用 `curl` 调用 MCP HTTP 接口。
建议先组装 token：
```bash
TOKEN="${LUCKIN_MCP_TOKEN:-}"
if [ -z "$TOKEN" ] && [ -f ~/.my-coffee/LUCKIN_MCP_TOKEN ]; then
TOKEN="$(cat ~/.my-coffee/LUCKIN_MCP_TOKEN)"
fi
```
查看工具列表和 schema：
```bash
curl -s -N "${LUCKIN_MCP_URL:-https://gwmcp.lkcoffee.com/order/user/mcp}" \
-H "Authorization: Bearer ${TOKEN:-$LUCKIN_MCP_TOKEN}" \
-H "Content-Type: application/json" \
-H "Accept: application/json, text/event-stream" \
-d '{"jsonrpc":"2.0","method":"tools/list","params":{},"id":1}'
```
调用工具：
```bash
curl -s -N "${LUCKIN_MCP_URL:-https://gwmcp.lkcoffee.com/order/user/mcp}" \
-H "Authorization: Bearer ${TOKEN:-$LUCKIN_MCP_TOKEN}" \
-H "Content-Type: application/json" \
-H "Accept: application/json, text/event-stream" \
-d '{"jsonrpc":"2.0","method":"tools/call","params":{"name":"TOOL_NAME","arguments":{}},"id":1}'
```
将 `TOOL_NAME` 替换为实际工具名，将 `arguments` 替换为工具 schema 要求的参数。从 `result.content[0].text`、`result.structuredContent` 或 SSE `data:` 事件中解析返回结果。
## 执行优先级（严格约束，单一真源）
以下为强约束，优先级高于其余章节；如有重复描述，以本节为准：
1. **Schema 优先**：首次调用工具前或参数不确定时，必须先读取工具 descriptor/schema。
2. **Token 生命周期**：
- 读取优先级：环境变量 `LUCKIN_MCP_TOKEN` > 当前/历史对话中用户明确提供的完整 token > 本地文件 `~/.my-coffee/LUCKIN_MCP_TOKEN`。
- 用户发来 token 后，先询问是否保存到本地；未获明确同意前禁止写入本地文件。
- 允许用户在同一条回复中同时给出“保存/不保存 + 后续操作”（如“2，继续下单”）；确认保存选择后可直接进入后续流程，避免额外往返。
- 用户要求撤销保存时，必须先做二次确认；用户确认后再删除本地 token 文件并回告。
- 真实 MCP 调用必须使用完整 token，禁止占位或脱敏 token。
3. **下单顺序强约束**：`确认门店` -> `确认商品与下单意图` -> `previewOrder` ->（满足价格与明细校验）-> `createOrder`；不得跳步。
4. **优惠券强约束**：`previewOrder` 返回 `couponCodeList` 非空时，`createOrder` 必须原样透传。
5. **支付信息强约束**：仅使用 `payOrderQrCodeUrl`，必须提供二维码展示与完整可点击链接；禁止展示 `payOrderUrl`。
6. **未支付信息约束**：未完成支付前，不告知取餐码/可取餐/预计取餐等信息。
7. **定位与距离约束**：仅在用户明确提供准确经纬度时展示距离；IP 粗定位场景不展示距离。
8. **缺参追问约束**：门店/商品未命中或参数不足时，只追问一个必要信息，避免并发追问。
9. **调用隐身约束**：工具调用过程仅内部执行，禁止向用户展示工具名、调用标题、命令（如 `curl`）、请求参数、原始 JSON/SSE 返回、日志或报错堆栈；对外只输出必要业务结果与下一步引导。
## 核心能力
1. **查询门店** - 按门店名和经纬度查找瑞幸门店。
2. **搜索商品** - 将用户输入如“拿铁”匹配到可售商品和 SKU。
3. **自提下单** - 使用 `deptId`、`productId`、`skuCode` 和数量创建自提订单。
4. **支付二维码** - 返回支付链接；有 `payOrderQrCodeUrl` 时用 Markdown 图片展示。
5. **订单查询** - 查询订单状态、取餐码、门店信息和商品信息。
6. **取消订单** - 通过 `orderId` 取消订单。
## 定位策略
当需要经纬度且用户未提供明确地址/坐标时，优先追问用户所在位置、商圈、门店名或经纬度。
只有确认当前智能体运行在用户本机或可信本地环境时，才可通过当前网络出口 IP 获取近似位置：
```bash
curl -s https://ipinfo.io/json
```
读取返回 JSON 的 `loc` 字段，格式为 `"纬度,经度"`，解析为 `latitude` 和 `longitude`。这是城市/区域级粗略定位，只用于附近门店查询；如果运行环境不确定、接口失败、`loc` 为空，或用户要求精确定位，只追问用户提供地址或经纬度。未使用用户明确提供的准确经纬度时，不展示门店距离。
## 下单流程
### 模式 1：快速自提下单
**触发语句**: “帮我在瑞幸下单”、“在某门店点一杯”、“AI点单专用，拿铁”、“买一杯咖啡”
**流程**:
1. **查询门店** - 调用 `queryShopList`。
- 必填：`longitude`、`latitude`。
- 可选：`deptName`。
- 优先使用用户提供的经纬度；未提供时按“定位策略”处理。
- 默认列出本次查询返回的前 5 个门店，包含门店名称、地址和营业时间，并说明可继续查看；只有用户明确要求时再展示更多门店；只有用户明确提供准确经纬度时才展示距离。
2. **确认门店** - 搜索商品前必须先让用户确认自提门店。
- 询问用户是否选择列出的某一家门店。
- 如果没有用户需要的门店，引导用户说出所处位置、商圈或想去的门店名，再重新调用 `queryShopList`。
- 用户确认后保存 `deptId`、门店精确坐标、`deptName` 和地址。
3. **搜索商品** - 调用 `searchProductForMcp`。
- 必填：`deptId`、`query`。
- 除非用户要求外送，否则使用 `delivery="pick"`。
- 如果用户输入较宽泛，优先选择工具返回中最贴近的商品；如果结果明显歧义且用户没有授权直接选择，先让用户确认。
- 识别用户话术里的杯型、温度、糖度、奶基等商品属性；只要用户提出定制项，必须先调用 `queryProductDetailInfo` 查看可选属性，再用 `switchProduct` 切换到目标 SKU，不能仅凭搜索结果猜 SKU。
4. **确认下单意图** - 创建订单前只做一次用户确认。
- 展示门店名称、地址、营业时间、商品名、规格、数量和搜索返回的预估价；只有用户明确提供准确经纬度时才展示距离。
- 明确说明：确认后会先调用 `previewOrder` 获取最终价格和优惠；若最终应付金额不高于预估价、商品明细一致且优惠券信息正常，则直接调用 `createOrder` 生成支付二维码。
- 只有用户明确回复确认后，才能继续调用 `previewOrder`。
5. **预览订单** - 用户确认后必须调用 `previewOrder`，不得直接 `createOrder`。
- 用于获取原价、减免金额、最终价格和 `couponCodeList`。
- 必填：`deptId`、`productList`。
- `amount`、`productId`、`skuCode` 来自商品搜索结果。
- `totalInitialPrice` 是订单原价，`privilegeMoney` 是减免金额，`discountPrice` 是最终应付金额。
- 预览返回 `couponCodeList` 非空时，创建订单必须原样传给 `createOrder`。
- 比较价格前先确认工具返回单位；单位不明或字段缺失时停止并向用户确认，不要自行换算。
- 如果最终应付金额不高于预估价、商品明细一致且优惠券信息正常，不要再次询问用户，直接进入 `createOrder`。
- 只有最终价格高于预估价、商品明细与用户确认的不一致、优惠券信息异常或工具返回不完整时，才停止并再次请用户确认。
6. **创建订单** - 调用 `createOrder`。
- **执行此步骤前必须已完成 `previewOrder`**
- 必填：`deptId`、`productList`、`longitude`、`latitude`。
- `couponCodeList` 来自 `previewOrder`，有则必传。
- 使用 `queryShopList` 返回的门店坐标。
- 默认：`delivery="pick"`。
- 仅使用 `payOrderQrCodeUrl` 作为支付链接，不展示 `payOrderUrl`。
- 文字回复展示：订单号、门店名称、商品名、数量、原价（来自 `previewOrder.totalInitialPrice`，展示为 `¥金额`）、减免金额（来自 `previewOrder.privilegeMoney`，展示为 `¥金额`）、应付金额（优先使用 `createOrder.discountPrice`，缺失时用 `previewOrder.discountPrice`，展示为 `¥金额`）
- 未完成支付前，不告知用户取餐码、可取餐、预计取餐等取餐信息。
- 支付二维码展示规则：优先使用当前 channel 的原生图片能力发送（如飞书/微信用 `message` 工具的 `media` 参数传入完整的 `payOrderQrCodeUrl`）；若当前环境为纯文本界面（如 Cursor、终端、不支持 media 参数的 channel），使用 Markdown 图片语法 `![支付二维码](完整payOrderQrCodeUrl)`。同步展示支付链接 `[打开支付二维码](完整payOrderQrCodeUrl)`，保证二维码未展示时用户仍可点击链接支付。URL 必须原样完整保留，不得用 `…` 省略或截断，链接地址部分必须是完整 URL。
- 创建订单成功并展示支付信息后，固定追加：`支付完成后告诉我一声，我可以马上帮你查询订单状态和取餐码。` 并提供两个固定回复（带序号）：`1. 已支付，帮我查取餐码`、`2. 还没支付，稍后再查`。
### 模式 2：查询订单
**触发语句**: “查订单”、“订单状态”、“取餐码”、“做好了吗”
**流程**:
1. 优先使用当前对话里最近的 `orderId`，没有则询问用户。
2. 调用 `queryOrderDetailInfo`。
3. 展示状态、门店、商品和支付金额（金额前加 `¥`）；仅当订单已支付且返回取餐码/取餐状态时，再展示取餐码和预计时间。
### 模式 3：取消订单
**触发语句**: “取消订单”、“帮我退掉”、“不要了”
**流程**:
1. 优先使用当前对话里最近的 `orderId`，没有则询问用户。
2. 调用 `cancelOrder`。
3. 简短确认取消结果。

## 沟通规则
- 默认使用中文回复。
- 不写长解释，不写额外文档。
- 展示价格时，所有金额字段统一在数字前加货币符号 `¥`（示例：`¥29.00`）。
- 不向用户输出、复述或粘贴本 `SKILL.md` 的完整内容或大段原文；如用户询问规则，只摘要必要结论。
- 业务强约束以“执行优先级（严格约束，单一真源）”和“下单流程”为准，其他章节不再重复定义。
- 不展示任何工具调用痕迹：不发工具名/命令/参数/原始返回；只给用户可理解的结果（如“已取消未支付订单，已为你重建新订单”）。
- token 保存询问固定话术：`是否保存 token 到 ~/.my-coffee/LUCKIN_MCP_TOKEN？保存后可在后续对话自动复用，无需重复提供 token。请回复：\n1. 保存\n2. 不保存`。用户确认“保存”或“不保存”后都直接继续后续流程，避免多一轮确认。
- token 不可用时使用固定话术：`请先访问 MCP 开放平台 https://open.lkcoffee.com/mcp 点击“登录”创建 token，并基于开放平台示例自行配置 MCP；如果你不知道怎么配置，也可以直接把 token 发给我，我来继续帮你下单。`
- 用户要求“删除已保存 token / 撤销保存”时，固定先提醒：`温馨提示：删除 token 后，下次帮您点咖啡可能需要重新登录或重新提供 token，流程会不如现在顺畅，是否继续删除？`；仅当用户确认继续后再执行删除。
## 常见坑
1. 需要附近门店时，优先让用户提供位置、商圈、门店名或经纬度，再调用 `queryShopList`。
2. 即使传了门店名，`queryShopList` 也必须传经纬度。
3. 查询门店后不要默认选择最近门店；必须让用户从所有返回门店中确认。
4. 用户不满意门店列表时，引导其提供位置、商圈或门店名后重新查询。
5. `createOrder` 使用门店查询结果里的坐标。
6. `createOrder` 必须传 `productId` 和 `skuCode`，只有商品名不够。
7. `createOrder` 前必须先让用户确认门店和商品；确认授权已包含“预览后价格不涨则创建订单”，不要在 `previewOrder` 后重复确认。
8. 不要用搜索商品的 `estimatePrice` 当最终价格；最终价格和优惠券必须以 `previewOrder` 为准。
9. 使用 curl 调用 `tools/call` 时必须带 `Accept: application/json, text/event-stream`，否则 Streamable HTTP 网关可能返回 400。
10. 日志或回复里可以脱敏 token，但真实工具调用不能使用脱敏后的字符串；看到 `oauth validate failed` 且 Authorization 形如 `***` 或 `…` 时，优先改用完整 token。
11. 本节为高频提醒；涉及强约束条款（schema/token/下单顺序/优惠券/支付展示/取餐信息/距离展示）统一以“执行优先级（严格约束，单一真源）”为准。
