+# 文档统计：总字数 / 总字符数
+
+当用户需要统计 Docx / Wiki 文档的总字数或总字符数时，使用本 skill 附带脚本 `scripts/doc_word_stat.py`。统计口径以该脚本为准，不要改用其他方式自行计算，也不要只读取 simple 摘要后统计。
+
+## 调用方式
+
+在线文档使用 XML full 内容，并让脚本读取 `docs +fetch --format json` 的 envelope：
+
+```bash
+lark-cli docs +fetch --doc "$URL" --doc-format xml --detail full --format json \
+  | python3 skills/lark-doc/scripts/doc_word_stat.py --protocol xml --lark-json --pretty
+```
+
+`$URL` 可以是用户给出的 docx/wiki URL，也可以是可被 `docs +fetch` 解析的 token。
+
+如需在自动化或回归验证中发现未覆盖块类型，追加严格参数：
+
+```bash
+lark-cli docs +fetch --doc "$URL" --doc-format xml --detail full --format json \
+  | python3 skills/lark-doc/scripts/doc_word_stat.py --protocol xml --lark-json --pretty --fail-on-unsupported --fail-on-unknown
+```
+
+## 如何读取结果
+
+脚本输出 JSON。对用户汇报时默认只读两个核心字段：
+
+- `word_count`：总字数。按语义单位统计汉字、英文单词/URL/code path、数字、中文标点；普通贴着英文的英文标点不计入，但独立 ASCII 符号、中文之间的 `/` 等以脚本结果为准。
+- `char_count`：总字符数。统计汉字、英文字母、数字、中英文标点和脚本识别的可见符号；空格不计入。
+
+其余字段用于排查或解释：
+
+- `breakdown`：拆分统计来源，例如 `han_chars`、`english_words`、`digits`、`chinese_punctuations`。
+- `unknown_blocks`：脚本遇到未知 XML/Markdown 块类型；通常表示需要扩展解析规则。
+- `unsupported_blocks`：脚本识别到块类型，但当前无法可靠提取可见文本。
+- `diagnostics.has_unknown` / `diagnostics.has_unsupported`：快速判断统计是否存在覆盖风险。
+
+如果 `unknown_blocks` 或 `unsupported_blocks` 非空，回复用户时要说明“已统计可提取文本，但存在未覆盖块，结果可能偏低”，并列出对应块类型。为空时可直接给出结果。
+
+## 输出示例
+
+输入正文等价于：`标题` + `一个苹果是 an apple。` 时，输出形态如下：
+
+```json
+{
+  "word_count": 10,
+  "char_count": 15,
+  "breakdown": {
+    "han_chars": 7,
+    "english_words": 2,
+    "number_words": 0,
+    "chinese_punctuations": 1,
+    "english_letters": 7,
+    "digits": 0,
+    "english_punctuations": 0,
+    "symbol_words": 0,
+    "symbol_chars": 0
+  },
+  "protocol": "xml",
+  "unknown_blocks": [],
+  "unsupported_blocks": [],
+  "diagnostics": {
+    "has_unknown": false,

+    "types": {},
+    "unknown_types": {},
+    "unsupported_types": {},
+    "actions": {}
+  }
+}

+

+2. 输入是长数字 `meeting_id`，不是 9 位会议号。若用户只给 9 位会议号，先按当前身份执行 `+meeting-list-active` 并按 `meeting_no` 匹配，匹配到唯一会议后再发送；不要为了发消息自动入会。

+6. 不要编造列表外的 `emoji_type`，也不要把 natural language 硬编码成不存在的 key；如果用户只给语义，可在完整列表中选择最接近的 key，无法判断时先确认。

+
+本 skill 对应 shortcut：`lark-cli vc +meeting-message-send`（调用 `POST /open-apis/vc/v1/bots/message`）。
+
+## 适用场景
+
+- 用户要求“在会里发一句话”“提示大家”“给当前会议发消息”。
+- 用户要求发送会中表情，例如“发个点赞”“发个 OK”“发个爱心”。
+- 用户要求表达会中反馈，例如“听不到”“看不到”“声音清楚”“效果不错”。
+- 只用于正在进行中的会议；已结束会议不支持。
+
+## 身份规则
+
+`meeting_id` 从哪种身份路径拿到，发送消息时就沿用哪种身份：
+
+| meeting_id 来源 | 发送时身份 |
+| --- | --- |
+| `+meeting-list-active --as user` | `+meeting-message-send --as user` |
+| `+meeting-list-active --as bot --user-id <user_open_id>` | `+meeting-message-send --as bot` |
+| `+meeting-join --as bot` 返回的 `meeting.id` | `+meeting-message-send --as bot` |
+
+不要把用户身份发现的 `meeting_id` 改用应用身份发送，也不要把应用身份发现的 `meeting_id` 改用用户身份发送，除非用户明确要求切换。
+
+## 参数
+
+| 参数 | 说明 |
+| --- | --- |
+| `--meeting-id` | 必填，长数字 `meeting_id`，不是 9 位会议号 |
+| `--msg-type` | 可选，`text` 或 `reaction`；只传 `--text` 或只传 `--emoji-type` 时可自动推断 |
+| `--text` | 文本消息内容 |
+| `--emoji-type` | 会中 reaction emoji key，大小写敏感，必须从本文“完整 `emoji_type` 列表”中选择 |
+| `--uuid` | 可选，幂等 key；不传则服务端生成 |
+
+CLI 会把 `--text` 或 `--emoji-type` 统一映射到 OpenAPI 请求体的 `content` 字段；`meeting_id` 也在请求体中传递。
+
+## 文本消息
+
+```bash
+lark-cli vc +meeting-message-send --as user --meeting-id <meeting_id> --text "稍等，我在看文档"
+```
+
+文本消息会出现在会议内的文本互动区。不要把它当成绑定群消息发送能力；如果用户明确要求发到群聊，路由到 `lark-im`。
+
+## 会中表情
+
+会中 reaction 支持普通 Feishu reaction emoji，也支持 4 个 VC 反馈 key。
+
+常见语义：
+
+| 用户表达 | 推荐 `emoji_type` |
+| --- | --- |
+| 点赞、赞一下、认可 | `THUMBSUP` |
+| +1、加一、附议、同上 | `JIAYI` |
+| OK、好的 | `OK` |
+| 收到、了解 | `Get` |
+| 爱心、红心 | `HEART` |
+| 喜欢、爱了 | `LOVE` |
+| 比心 | `FINGERHEART` |
+| 看起来没问题、可以继续 | `LGTM` |
+| 搞定、已完成 | `DONE` |
+| -1、减一 | `MinusOne` |
+| 不赞同、踩 | `ThumbsDown` |
+| 听不到、没声音 | `VC_NoSound` |
+| 看不到、画面有问题 | `VC_CanNotSee` |
+| 声音清楚 | `VC_SoundsClear` |
+| 会议画面效果不错、画面看起来可以 | `VC_LooksGood` |
+
+```bash
+lark-cli vc +meeting-message-send --as bot --meeting-id <meeting_id> --msg-type reaction --emoji-type LOVE
+lark-cli vc +meeting-message-send --as bot --meeting-id <meeting_id> --msg-type reaction --emoji-type VC_NoSound
+```
+
+不要编造列表外的 `emoji_type`，也不要把 mixed-case 值改成全大写，例如 `EatingFood`、`CheckMark`、`StatusInFlight` 都要按原值传。
+
+如果用户给的是自然语言语义，可以在下方列表中选择语义最接近的 key；如果不确定，先向用户确认。

+## 9 位会议号处理
+
+如果用户给的是 9 位会议号并要求发送会中消息：
+
+1. 先按当前身份执行 `+meeting-list-active`。
+2. 在返回结果中按 `meeting_no` 匹配该 9 位会议号。
+3. 匹配到唯一会议后取长数字 `meeting_id`。
+4. 用发现该会议时的同一身份执行 `+meeting-message-send`。
+
+匹配失败时不要自动入会。只有用户明确要求“让应用机器人入会/旁听/代参会”时，才改用 `+meeting-join`。
+
+## 权限和前置条件
+
+- 用户身份：当前用户必须正在该会议中。
+- 应用身份：应用机器人必须正在该会议中。
+- 会议需要开启会中智能体/Agent 能力开关。
+- 需要 `vc:meeting.message:write` 权限；应用身份还需要应用已安装、数据范围已配置。
+
+应用身份权限错误时，不要引导用户反复 `auth login`。按主 skill 的“应用身份权限配置检查”处理。
