 ## 🚀 快速开始

-### 前置要求
+### 使用前置要求

- 微信<=4.0 需要获取自己微信本地数据库的密码， 获取方式参考： [Mac 导出微信聊天记录](https://blog.vcvit.me/2024/08/02/mac-export-wechat-chat-records/)
- 如果无法获取本地数据库密码 则无法使用当前项目
+- **微信版本**:
+  - 微信 4.0+: 已支持部分能力，仍在持续迭代与兼容性验证中；如需更成熟的完整方案，推荐使用 [WeFlow](https://github.com/hicccc77/WeFlow) [Chatlog](https://github.com/sjzar/chatlog)
+- 如无法获取本地数据库密码，则无法使用当前项目
 - Node.js (推荐 v16+)
- pnpm (推荐) 或 npm
+- pnpm@7
 - 解密后的微信数据库文件 (`.db`) 和对应的密钥
- [DeepSeek API Key](https://www.deepseek.com/) (用于 AI 总结功能)
+- AI API Key（支持 OpenAI 兼容 API，可选 DeepSeek/GPT/Claude/Moonshot 等）

-### 安装
+### 环境变量配置 (.env)
+
+可选配置项，可在 `.env` 文件中设置：
+
+| 变量名                  | 说明                        | 示例                        |
+| ----------------------- | --------------------------- | --------------------------- |
+| `VITE_DB_KEY`           | 微信数据库密钥 (32字节hex)  | `YOUR_DB_KEY_HERE`          |
+| `VITE_IMAGE_XOR_KEY`    | 图片解密 XOR 密钥 (hex格式) | `0x40`                      |
+| `VITE_IMAGE_AES_KEY`    | 图片解密 AES 密钥 (16字符)  | `YOUR_AES_KEY_HERE`         |
+| `VITE_DEEPSEEK_API_KEY` | DeepSeek API Key            | `sk-xxx`                    |
+| `VITE_AI_BASE_URL`      | AI API 地址                 | `https://api.deepseek.com`  |
+| `VITE_AI_MODEL`         | AI 模型                     | `deepseek-chat`             |
+| `VITE_FILTER_MSG_TYPES` | 过滤的消息类型              | `分享消息,图片,表情包,视频` |
+
+#### 图片解密密钥说明
+
+微信 4.0+ 的图片以 `.dat` 文件存储，需要密钥解密：
+
+- **XOR Key**: 单字节 hex 值（如 `0x40`），用于简单的字节异或解密
+- **AES Key**: 16字符字符串，用于 AES-128-ECB 解密
+
+这两个密钥可以通过以下方式获取：
+
+1. 从 WeFlow/Chatlog 设置中导出
+2. 使用内存扫描工具从微信进程中自动提取（待实现）
+
+## 🤖 AI 集成（本地 HTTP API）
+
+WechatExplorer 内置了一个本地 HTTP API 服务，默认监听 `127.0.0.1:6131`（纯本地，无鉴权），让你能够从 **Claude Desktop / Claude Code / Codex / curl / 任何脚本** 读取已经解锁的微信聊天记录。
+
+### 启用本地 API
+
+API 服务在 WechatExplorer 启动时自动启用，**不需要任何配置**。只需要：
+1. 安装并启动 WechatExplorer
+2. 完成首次密钥配置（主窗口第一步），解锁 WCDB 数据库
+3. API 即在 `http://127.0.0.1:6131` 可用
+
+### 7×24 提供 API（菜单栏常驻模式）
+
+默认情况下，关闭主窗口时 macOS 会让 app 继续运行，但 Windows / Linux 会退出。如果希望主窗口关闭后 API 服务仍可用，启用菜单栏模式：

 ```bash
-# 克隆项目
-git clone https://github.com/your-username/WechatExplorer.git
-
-# 进入目录
-cd WechatExplorer
-
-# 安装依赖
-pnpm install
+# 任选一种方式
+WXE_TRAY=1 open /Applications/WechatExplorer.app
+/Applications/WechatExplorer.app/Contents/MacOS/WechatExplorer --tray
 ```

-### 配置
+启用后：
+- macOS dock 图标自动隐藏
+- 菜单栏出现 WechatExplorer 图标（可点击重新打开主窗口、查看 API 状态）
+- 主窗口关闭后 API 服务继续运行

-复制 `.env.example` 文件为 `.env`，并填写相关配置（可选，也可以在应用内设置）：
+### API 端点一览
+
+| 端点 | 说明 |
+|------|------|
+| `GET /api/v1/health` | 健康检查 |
+| `GET /api/v1/current_time` | 获取当前本地时间（用于"今天/昨天"换算） |
+| `GET /api/v1/contact?filter=xxx` | 联系人 / 群聊列表 |
+| `GET /api/v1/chatroom?keyword=xxx` | 搜索群聊 |
+| `GET /api/v1/chatlog?talker=xxx&time=2026-07-03` | 聊天记录 |
+| `GET /api/v1/group_snapshot?md5=xxx` | 群成员快照 |
+| `GET /api/v1/resolve?q=群昵称` | 把昵称/wxid/md5 解析成 md5 |
+
+详细参数、返回结构、时间格式见 [`docs/skill/wechatexplorer-reader/SKILL.md`](./docs/skill/wechatexplorer-reader/SKILL.md)。
+
+### 让 Claude 自动总结你的群聊
+
+复制 [`docs/skill/wechatexplorer-reader/SKILL.md`](./docs/skill/wechatexplorer-reader/SKILL.md) 到 `~/.claude/skills/`，然后在 Claude Desktop 里说：
+
+> "今天 技术交流群 聊了啥？"
+
+Claude 会自动：
+1. 调 `current_time` 拿到今天日期
+2. 调 `chatroom` 找到目标群
+3. 调 `chatlog` 拿 JSON 聊天记录
+4. 自己用 LLM 生成总结报告
+
+### curl 示例

 ```bash
-cp .env.example .env
-```
+# 健康检查
+curl http://127.0.0.1:6131/api/v1/health

-### 开发模式运行
+# 今天 摸鱼交流群 的聊天记录
+curl -G "http://127.0.0.1:6131/api/v1/chatlog" \
+  --data-urlencode "talker=摸鱼交流群" \
+  --data-urlencode "time=$(date +%Y-%m-%d)"

-```bash
-pnpm dev
-```
-
-### 打包构建
-
-```bash
-# Windows
-pnpm build:win
-
-# macOS
-pnpm build:mac
-
-# Linux
-pnpm build:linux
+# 把群昵称解析成 md5
+curl -G "http://127.0.0.1:6131/api/v1/resolve" \
+  --data-urlencode "q=摸鱼交流群"
 ```

+description: 通过本地 HTTP API 读取 WechatExplorer 解锁后的微信聊天数据(本地服务由 WechatExplorer.app 提供)。当用户提到微信聊天记录、群消息、看看群里说了什么、查一下微信、分析微信对话、总结群聊等场景时,使用此技能。注意:此技能的数据源是用户本机 WechatExplorer app,而非 chatlog/WeFlow。
+---
+
+# WechatExplorer Reader
+
+通过本地 HTTP API(`http://127.0.0.1:6131`)读取 WechatExplorer 已经解锁的微信数据库内容。
+
+## 数据源
+
+- **本服务由 WechatExplorer.app 提供**,数据完全在本地处理,不会上传任何服务器
+- 用户必须在 WechatExplorer 主窗口完成**首次密钥配置**(解锁 WCDB 数据库)
+- 默认监听 `127.0.0.1:6131`,仅本机可访问,无需鉴权
+
+## 前置条件
+
+1. **安装并启动 WechatExplorer.app**(从项目 release 页面下载)
+2. **首次启动时完成密钥配置**:在主界面第一步输入微信数据库密钥(64 位 hex),完成 WCDB 初始化
+3. **如需 7×24 提供 API**:用 `WXE_TRAY=1` 或 `--tray` 参数启动 app,启用菜单栏常驻模式(主窗口关闭后服务仍在)
+
+## API 列表
+
+GET 用于读取数据,`POST /api/v1/report` 用于生成群日报(HTML + 长图)。所有端点返回 JSON。
+
+| 端点 | 用途 | 关键参数 |
+|------|------|---------|
+| `GET /api/v1/health` | 健康检查 + 是否已初始化 | — |
+| `GET /api/v1/current_time` | 获取当前本地时间(用于"今天/昨天"换算) | — |
+| `GET /api/v1/contact` | 联系人 / 群聊列表 | `filter`(昵称模糊)、`type`(`user` \| `group`) |
+| `GET /api/v1/chatroom` | 群聊列表(等同 contact?type=group) | `keyword` |
+| `GET /api/v1/recent_chat` | 最近会话 | `limit`(默认 50) |
+| `GET /api/v1/chatlog` | 聊天记录 | `talker`、`time` 或 `startTime`/`endTime` |
+| `GET /api/v1/group_snapshot` | 群成员快照 | `md5` |
+| `GET /api/v1/resolve` | 把昵称/wxid/md5 解析成 md5 | `q` |
+| `POST /api/v1/report` | 生成群聊日报 HTML + 长图 PNG | JSON body(见下文,推荐传 `metadata.talker` 让服务端自动反推真头像) |
+
+### `talker` 参数可接受的值
+
+`chatlog` 和 `recent_chat` 的 `talker` / 列表项 ID 支持以下三种形式,服务端会按 `nickname → wxid → md5` 顺序匹配:
+
+1. **群昵称 / 好友备注**(模糊匹配,如 `技术交流`、`摸鱼群`)
+2. **微信 wxid**(如 `wxid_abc123`、`gh_xxxxx@chatroom`)
+3. **会话 md5**(如 `49023470180@chatroom` 的 md5 哈希,可在 `contact` 接口里看到)
+
+不确定时先调 `GET /api/v1/resolve?q=<输入>` 校验,返回 `{ md5, m_nsUsrName, m_nsNickName, type, ... }`。
+
+### `chatroom` 与 `contact?type=group` 字段一致性
+
+`/chatroom` 和 `/contact?type=group` 返回的是**同一个集合**(都是 `listContacts().filter(type==='group')`),字段也完全一致:
+
+```json
+{
+  "m_nsUsrName": "49023470180@chatroom",   // wxid, 用作 chatlog 的 talker
+  "m_nsNickName": { "buffer": "...", "type": "Buffer" },  // nickname 原 buffer
+  "type": "group",
+  "md5": "..."
+}
+```
+
+需要 `displayName` 时从 `m_nsNickName` 里解析;需要拉消息就传 `m_nsUsrName` 当 talker。
+
+## 时间范围格式(`time` 参数)
+
+支持以下格式:
+
+| 输入 | 含义 |
+|------|------|
+| `2026-07-03` | 单日 00:00:00 ~ 23:59:59 |
+| `2026-07-01~2026-07-03` | 日期范围(闭区间) |
+| `2026-07-03/14:30` | 单分钟(从 14:30:00 起 60 秒) |
+| `2026-07-03/14:30~2026-07-03/15:30` | 精确到分钟的范围 |
+
+也可以直接传 unix 秒级时间戳作为 `startTime` 和 `endTime`。
+
+### "今天 / 昨天 / 本周" 的时区语义
+
+所有 `time` / `startTime` / `endTime` 都按**用户本机时区**解析(由 `current_time` 里的 `timezone` 字段给出,典型为 `Asia/Shanghai`)。含义如下:
+
+- "今天 2026-07-03" → 本机 2026-07-03 00:00:00 ~ 23:59:59(北京时间 24 小时),**不是** UTC 当天
+- "昨天" → 本机昨天 0 点 ~ 23:59:59
+- "本周" → 本周一 0 点 ~ 当前时刻(按本机时区所在周的周一)
+
+跨时区时(如用户在国外):仍以本机时区为准,需要按 UTC 处理时显式传 unix 时间戳。
+
+## 时间预检工作流(Time-Aware Workflow)
+
+**重要**:只要用户请求中包含"今天"、"昨天"、"本周"、"刚才"等相对时间概念,**禁止**直接生成日期字符串。
+
+**步骤 1**:先调用 `current_time` 工具获取本地 RFC3339 时间。
+**步骤 2**:根据返回的时间计算对应的 `time` 参数。
+**步骤 3**:用计算后的参数调 `chatlog`。
+
+示例:
+- 用户: "今天 摸鱼交流群 聊了啥?"
+- AI: 先 `GET /api/v1/current_time` → 得到 `2026-07-03T14:30:00+08:00` → 计算 `time=2026-07-03` → `GET /api/v1/chatlog?talker=摸鱼交流群&time=2026-07-03`
+
+## 多步上下文检索(强制)
+
+当查询特定话题或特定发送者发言时,**必须**按以下流程操作:
+
+1. **初步定位**:用 `contact` 或 `chatroom` 端点确定群聊 md5 / wxid
+2. **粗查**:用 `chatlog` + 较宽时间范围找到相关消息时间点
+3. **精查**:对每个关键时间点分别查前后 15-30 分钟(不带任何 keyword 过滤),用完整上下文分析
+
+**禁止**:仅凭一次粗查结果直接回答用户。
+
+## 生成群日报(POST /api/v1/report)
+
+当用户希望输出**可视化群日报**(长图 PNG + HTML 邮件版)时,用这个端点。WechatExplorer 内置 `mobile_daily_report.html` 模板,渲染后会同时落盘 `htmlPath` 和 `pngPath`,并返回 `imageDataUrl` 可直接预览。

+- `heroParticipants`:数组,模板会把每个名字当 key 去 `metadata.avatars[name]` 取头像图
+- `avatars`:对象,**每个 `heroParticipants` 里的名字都必须有这个 key**(没有就传 `""`,**不要省略整段**),否则模板渲染会抛 `Cannot read properties of undefined (reading '<名字>')` 报 500
+
+`report` 的以下字段**必须存在**(空就传 `[]`,**不能省略**),否则模板遍历时会抛 `Cannot read properties of undefined (reading 'map')` 报 500:
+
+- `report.topics`(至少 1 个,完全没话题就改用纯文本总结,不要硬生成空日报)
+- `report.resources`
+- `report.importantMessages`
+- `report.quotes`
+- `report.qa`
+- `report.analytics.topicHeat`
+- `report.analytics.topSpeakers`(至少 1 个)
+- `report.keywords`
+
+最小安全示例:
+
+```json
+{
+  "report": {
+    "overview": "...",
+    "topics": [],
+    "resources": [],
+    "importantMessages": [],
+    "quotes": [],
+    "qa": [],
+    "analytics": { "topicHeat": [], "activeTimeline": "", "topSpeakers": [] },
+    "keywords": []
+  },
+  "metadata": {
+    "groupName": "技术交流",
+    "reportDate": "2026-07-07",
+    "dateRange": "2026-07-07 全天",
+    "heroParticipants": ["张三", "李四"],
+    "avatars": { "张三": "", "李四": "" }
+  }
+}
+```
+
+`report.importantMessages[].time` 用 `HH:mm` 格式(不要 ISO 时间戳);`report.analytics.topicHeat[].score` 数字 0-10。
+
+### 4 个数字格子的内容必须紧凑(避免塌陷)
+
+模板顶部的 4 个统计格(`消息数 / 活跃人数 / 时间跨度 / 主要话题`)宽度均分,内容过长会被截断或换行:
+
+| 字段 | 推荐格式 | 反例(会撑爆格子) |
+|------|---------|----------------|
+| `metadata.messageCount` | 纯数字 `"1234"` | `"约 1.2k 条"` |
+| `metadata.activeUsers` | 纯数字 `"56"` | `"大约 50 多人"` |
+| `metadata.timeSpan` | **持续时长紧凑半角** `"1 h"` / `"30 min"` / `"2 d"` | `"1 小时"` / `"7 小时"` / `"1天3小时"` |
+| `metadata.topicCount` 等 | 数字 / 短中文 | 长句子 |
+
+`timeSpan` 是**首条到末条消息的持续时长**,不是时间区间。**单位用半角空格分隔**:
+
+- `< 1 h` → `"30 min"`
+- `1~24 h` → `"1 h"` / `"7 h"`(整数,向上取整)
+- `> 24 h` → `"2 d"`(整数,向上取整)
+
+**首末条消息的具体时间点**:`dateRange` 字段会显示完整日期 + 起止时间(无长度限制),模板里 dateRange 是 hero 区的副标题,跟 stat 格子分开。
+
+**区间叙事**(如"主要集中在上午 10 点-12 点")放 `report.analytics.activeTimeline`,那是模板里单独一段的描述,不被 stat 格子限制。
+
+**不传 timeSpan**:服务端会用空字符串渲染(stat 格会空),subagent 应当总是算好时长填进来,或者 renderer 端会自动算(见 renderer 源码)。
+
+### 头像:服务端自动反推(推荐)
+
+**v1.4 起无需手动拼 `avatars` 字典**。在 `metadata` 里加 `talker`(群昵称/wxid/md5 都行),服务端会用 `getGroupSnapshot` 拉全量群成员,按 `nickname → avatar` 自动反推填进 `metadata.avatars`。LLM 总结里出现的 `heroParticipants` / `topics[].participants` / `topSpeakers[].name` 等所有名字都会被覆盖。
+
+**优先级**:客户端传的 `avatars[name]`(非空字符串) > 服务端反推 > 占位 SVG(姓名首字母 + 随机色块)。
+
+**回退**:不传 `talker` 时按 `metadata.avatars` 字典取;还取不到则生成 SVG 占位(`fallbackAvatar`),**不会变空白方块**(v1.4 修了 data URL 正则,SVG 占位能正常嵌入)。
+
+**手动覆盖**:仍可传 `avatars` 字典强制使用自定义头像,例如 `{"张三": "data:image/jpeg;base64,..."}`。
+
+**P2 风险**:群里有两人同名(如"杨伟")时,服务端只取首条;客户端可手动覆盖。
+
+## 隐私安全原则
+
+1. **最小化原则**:只返回用户明确请求的内容,不过度展开无关聊天
+2. **本地处理**:所有数据来自用户本机,API 不缓存、不转发
+3. **摘要优先**:对于大量聊天记录,先提供摘要而非完整 dump
+4. **用户确认**:涉及敏感内容时,先展示摘要,让用户决定是否继续深入
+
+## 典型工作流示例
+
+**示例 1:今日群聊总结(纯文本)**
+1. `GET /api/v1/current_time` → 获取今天日期
+2. `GET /api/v1/chatroom?keyword=技术交流` → 找到目标群 md5
+3. `GET /api/v1/chatlog?talker=技术交流&time=2026-07-03` → 拉取今天的聊天
+4. AI 用 LLM 生成总结报告(话题 TOP N、最活跃发言者等)
+
+**示例 2:搜索特定消息上下文**
+1. `GET /api/v1/chatlog?talker=摸鱼群&time=2026-07-01~2026-07-03` → 粗查近 3 天
+2. 在返回的消息中定位关键词出现的时间点 T1, T2, ...
+3. 对每个 Ti 分别查 `chatlog?talker=摸鱼群&time=Ti-15min~Ti+15min`,分析上下文
+
+**示例 3:群日报(可视化长图)**
+1. `GET /api/v1/chatlog?talker=技术交流&time=2026-07-03` → 拉今天聊天
+2. LLM 按上方 `GroupDailyReport` schema 总结出 `report` + `metadata`
+3. `POST /api/v1/report` body = 上述 JSON → 拿到 `htmlPath` / `pngPath` / `imageDataUrl`
+4. 把 `imageDataUrl` 给用户预览,把 `pngPath` 路径告诉用户用 Finder 打开
+
+## 错误处理
+
+- `503` → WechatExplorer 未初始化(密钥未配置),提示用户在主窗口完成配置
+- `404 talker not found` → talker 不存在,先调 `contact` 或 `resolve` 确认 md5/wxid
+- `400 missing required parameter` → 检查必填参数(talker / md5 / q)
+- `200` 但 `result.warnings: ['enrich skipped: talker "X" not found']` → `/report` 的 `metadata.talker` 解析失败,头像走 SVG fallback(不阻断生成)
+- `200` 但 `result.warnings: ['enriched N member avatars from snapshot (M members)']` → enrich 成功(诊断用)
+- `400 请求体为空 / 需包含 report 和 metadata` → 调用 `/report` 时 body 必须是非空 JSON,且有这两个顶层字段
+- `500 success=false` → 模板渲染失败,通常因 `report` 字段缺失或 `metadata.groupName/reportDate` 为空,检查后重试
+
+## 配置 Claude Desktop
+
+把以下加入 `~/Library/Application Support/Claude/claude_desktop_config.json`:
+
+```json
+{
+  "mcpServers": {
+    "wechatexplorer": {
+      "command": "npx",
+      "args": ["-y", "@wechatexplorer/mcp-bridge"]
+    }
+  }
+}
+```
+
+(待 P3 实现 — MCP bridge 包,在此之前可直接用 `curl` 调用 HTTP API,或通过 mcp-remote 桥接。)
+
+## 配置 Claude Code / Codex
+
+在 `~/.claude/settings.json` 或项目级 `.claude/settings.local.json` 中:
+
+```json
+{
+  "mcpServers": {
+    "wechatexplorer": {
+      "url": "http://127.0.0.1:6131"
+    }
+  }
+}
+```
+
+(视 MCP over HTTP 支持情况调整)

+
+总原则：
+1. 不得编造聊天中没有的事实、结论、参与者或链接内容。
+2. 仅使用输入中的昵称，不输出 wxid、微信 ID、会话 ID 等内部标识。
+3. 图片、表情、语音、视频或链接内容不可见时，只能描述消息类型、互动效果和上下文，不能猜图片具体内容。
+4. 先合并同一事件，再按重要性排序，避免一个事件在多个模块大段重复出现。
+5. 优先保留结论、待办、未解决问题、明确通知，再保留趣味内容。
+6. 负责人、截止日期、图片内容必须有聊天证据；没有证据就返回 null 或省略。
+7. 不为了填满模板而生成内容，没有就输出空数组。
+8. 所有候选条目尽量返回 sourceMessageIds，便于程序去重和追溯。
+9. 精简版面向 30 秒阅读，摘要必须短；完整版可以保留更多候选项。
+10. 只输出一个可被 JSON.parse 解析的 JSON 对象，不要输出 Markdown 代码块或其他文字。
+
+JSON 结构必须为：

+  "hero": {
+    "headline": "一句抓重点的日报标题",
+    "summary": "一句总结今天发生了什么，最多3行",

+- 精简版：热点最多4个、重要消息最多4条、待办最多5条、未解决最多3条、名场面最多2组、每组最多4条、关键词最多12个。
+- 完整版：可以保留更多候选项，但仍要去重和排序。
