+
+Base 数据查询与分析任务的执行契约。覆盖记录读取、筛选、排序、Top/Bottom N、聚合统计、分组聚合、多表关联、临时分析和查询后写入前的目标定位。
+
+具体命令参数不要在本文猜；需要时跳到对应 reference：
+
+- `+data-query`: [lark-base-data-query.md](lark-base-data-query.md)
+- 视图筛选/排序/投影: [lark-base-view-set-filter.md](lark-base-view-set-filter.md), [lark-base-view-set-sort.md](lark-base-view-set-sort.md), [lark-base-view-set-visible-fields.md](lark-base-view-set-visible-fields.md)
+- 记录读取: [lark-base-record.md](lark-base-record.md)
+
+## 0. Hard Rules
+
+- 全局问题不能用默认 `+record-list --limit N` 片面地回答。
+- `jq` / shell / 本地代码是在个人电脑或当前运行环境中处理已返回数据，只适合小范围结果；超过 200 行默认不推荐本地统计、排序或求极值，应改用 Base 云端查询服务的 filter/sort/aggregate。
+- “最高、最低、最新、最早、Top、Bottom、总数、全部、异常、最大、最小、最多、最少、优先级最高”等全局语义，必须在 Base 云端查询服务中完成筛选、排序或聚合。
+- `+record-search` 用于关键词检索字段的展示文本；可搜多类字段，但匹配的是文本表示（如人员命中 name），不要用它替代金额、状态、日期、空值等结构化条件。
+- 不要依赖已有视图，除非用户明确指定该视图，或你已读取并验证其 filter/sort/projection 符合当前问题。
+- 交付输出必须使用用户可读的真实字段值；内部 ID、`record_id`、关联记录 ID、open_id、编码字段只可作为连接键或定位键，不能替代最终输出，除非用户明确要求输出这些键值。
+- 每次读取必须做最小投影，并包含后续解释、回查或写入需要的业务 key。

+
+## 2. Execution Patterns
+
+### 2.1 结构化明细与 TopN
+
+使用视图路径：
+
+1. `+field-list` 确认筛选字段、排序字段、展示字段、业务 key。
+2. `+view-create` 创建 grid 视图。
+3. 设置 filter/sort/visible fields。
+4. `+record-list --view-id <view_id> --limit <N>` 读取结果。
+
+不要从未筛选、未排序的全表输出中手动挑选。一次性查询可用临时视图；如果这个筛选/排序结果对用户后续查看有价值，应保留为持久视图，不要删除，并告知用户视图名称和用途。视图参数细节见 view-set references。
+
+### 2.2 聚合分析与 TopN
+
+使用 `+data-query`：
+
+- 让 Base 云端查询服务完成 filters、dimensions、measures、sort、pagination.limit。
+- `pagination.limit` 是 Base 云端查询服务中的聚合结果限制，不是本地分页扫描。
+- 需要输出明细或用户可读字段时，先拿业务 key，再用 record 路径精确回查。
+- 字段类型、日期 value、DSL shape 以 [lark-base-data-query.md](lark-base-data-query.md) 为准。
+
+### 2.3 关系查询与回查
+
+- link 单元格通常是关联表 `record_id` 数组，不是用户可读内容，只是连接键。
+- 先用 `+field-list` 确认 link 字段的 `link_table`、业务唯一键和展示字段。
+- 从驱动表拿到候选记录后，用关联 `record_id` 到关联表 `+record-get` 批量读取记录内容。
+- 多跳关系逐跳建立 `record_id/key -> 用户可读字段` 映射；最终用户可读的信息。
+
+禁止：
+
+- 把 link `record_id` 当最终输出。
+- 用 `+record-search` 搜 link `record_id`。
+- 基于 ID、自增编号、link 值做语义猜测；禁止依赖字段先验、样本记忆补全交付输出。
+
+## 3. Range & Pagination Contract
+
+- `+record-list` 默认页、固定 `--limit`、本地 `jq`、shell 管道、手工浏览输出，都只覆盖已读取范围；超过 200 行不要把本地处理当作推荐路径。
+- `has_more=true`、存在下一页 offset/page token、或返回行数等于 page size，都表示可能还有未读取数据。
+- 对全局问题，只有 Base 云端查询服务已经通过 filter/sort/aggregate 收敛目标范围，或 `data-query` 已在云端完成聚合、排序和限制时，才可以用有限返回形成结论。
+- 必须全量导出时，按 CLI 分页语义串行翻页；不要并发调用 `+record-list`。
+
+## 4. Final Answer Check
+
+形成交付输出前必须能确认：
+
+- 问题范围是局部样例、单点定位、全局明细、聚合分析、多表关联，还是查询后写入。
+- 筛选、排序、聚合是否发生在 Base 云端查询服务中，而不是本地 `jq` / shell 中。
+- 如果使用 `jq` / shell，本地输入是否是 200 行以内的小范围结果；超过 200 行是否已改用 Base 云端查询服务查询。
+- 如果使用 `+record-list`，是否处理了 `has_more`，且投影包含业务 key 和解释字段。
+- 如果涉及关系查询，是否按 `record_id` 或业务 key 精确回查，交付输出是否来自关联表真实字段。
+- 交付输出能追溯到表、字段、筛选条件、排序/聚合条件和连接键。
+
+任一项无法确认时，继续查询或明确说明只能得到局部结论。

-记录读取由 6 个功能组合完成：选路、字段投影、视图预处理、分页与范围、返回结构解释、link 关联读取。
-
-## 1. 读取选路
-
-| 场景 | 使用方式 | 规则 |
-|------|------|------|
-| 已知 `record_id` | `+record-get` | 只读单条记录，不要用 search/list 反查。 |
-| 明确关键词检索 | `+record-search` | 只用于文本关键词检索；金额、状态、日期等结构化条件不要用 search。 |
-| 普通明细读取 / 导出 / 查看前 N 条 | `+record-list` | 优先加 `--view-id` 时只读该视图可见记录与可见字段；或者加 `--field-id` 手动裁剪字段；不传 `--view-id` 时会读取全表。 |
-| 明确筛选 / 排序 / Top N / Bottom N 且需要原始记录或 `record_id` | 创建带 filter + sort 的临时视图 + `+record-list --view-id` | 让视图完成 filter/sort projection，LLM 不擅长手工筛选排序，建议用视图完成。 |
-| 统计 / 聚合结果且不需要 `record_id` | 转到 [`lark-base-data-query.md`](lark-base-data-query.md) | `data-query` 是特殊分析 DSL，不是记录读取工具。 |
-
-## 2. 字段投影
-
-- `FieldListFirst`: 不清楚字段结构时先 `+field-list`，确认筛选字段、排序字段、展示字段、关联字段、业务唯一键字段。
-- `UseRealField`: 字段名和字段 ID 必须来自 `+field-list` 返回，不要凭自然语言猜字段名。
-- `MinimalProjection`: 每次读取只返回本次任务需要的字段；`+record-list` 用重复 `--field-id`，视图读取用 `+view-set-visible-fields`。
-- `FieldScopePriority`: 返回字段优先级为显式投影字段（`+record-list --field-id` / `record-search select_fields`） > 视图可见字段 > 全表字段；需要稳定列范围时必须显式投影。
-- `LongFieldAvoidance`: 默认不要读取 `trace`、`raw`、长文本、附件等高噪声字段，除非任务明确需要。
-- `BusinessKey`: 后续要定位、更新或解释记录时，投影中必须包含可识别业务字段，例如订单号、日报ID、姓名、编号。
-
-## 3. 视图预处理
-
-适用于结构化筛选、排序、最高/最低、倒数、Top/Bottom N、按条件找记录等场景。
-
-1. `+field-list` 获取字段 ID、字段名和字段类型。
-2. `+view-create` 创建临时 `grid` 视图，名称带任务语义，例如 `tmp_query_销售额升序`。
-3. `+view-set-filter` 设置筛选条件；空值是否参与必须按用户语义判断。
-4. `+view-set-sort` 设置排序条件；最高/最新用降序，最低/最早/倒数用升序。
-5. `+view-set-visible-fields` 设置投影字段，只保留业务键、排序字段、筛选解释字段、需要展示或二跳的字段。
-6. `+record-list --view-id <view_id> --limit <N>` 读取结果；不要再从未排序全表输出中手动挑选。
-
-## 4. 分页与范围
-
-- `ViewScope`: URL 带 `view_id` 时先判断用户是否要求“该视图下”；全表问题不要误用 URL 视图范围，应该根据需求创建合适的临时视图完成查询任务。
-- `ViewIdScope`: `+record-list --view-id` 是作用域参数；仅用于用户指定的视图，或本次任务主动创建的临时筛选 / 排序 / 投影视图。
-- `NeedAllPages`: 用户要求全部、导出、统计、最高/最低且未用视图/limit 限定时，必须检查 `has_more` 并串行翻页。
-- `LimitWhenScoped`: 用户只要示例、前 N 条、Top/Bottom N，使用 `--limit` 控制结果规模。
-- `NoConcurrentList`: `+record-list` 禁止并发调用；分页和多表读取必须串行。
-- `DataQueryScope`: `data-query` 的筛选 DSL 与视图筛选不是同一套语法；不要混用。
-
-## 5. 返回结构解释
-
-- `ColumnMapping`: `fields` / `field_id_list` 定义 `data` 每列含义；解释记录前先建立列到字段名的映射。
-- `RowMapping`: `record_id_list[i]` 与 `data[i]` 是同一行；需要后续定位、更新或关联时，按下标整理成 `record_id + 字段名:值` 的小表。
-- `BusinessMatch`: 后续引用目标记录时按业务字段匹配，不靠肉眼数行号。
-- `FieldType`: 按字段类型解释值；数字、货币、日期、人员、formula、lookup、attachment、link 不要当普通文本处理。
-- `EmptyValue`: 空值参与筛选或排序前必须明确语义；不要默认把空值当 `0`、空字符串或有效状态。
-- `AnswerCheck`: 最终回答前复核答案记录来自读取结果、筛选排序已应用、字段含义和 record_id 映射无误。
-
-## 6. link 关联字段读取
-
-link 字段是关联单元格；读取结果通常是关联表的 `record_id` 数组，不是用户可读名称。
-
-| 步骤 | 做法 |
-|------|------|
-| 识别 link 字段 | 用 `+field-list` 查看字段类型为 `link`，并读取 `link_table` 确认关联目标表。 |
-| 读取当前表 | 在当前表 `+record-list` / `+record-get` 中保留 link 字段和业务键字段。 |
-| 解析单元格值 | link 单元格通常形如 `[{"id":"rec..."}]`；提取其中每个 `id` 作为关联表 `record_id`。 |
-| 读取关联表 | 到 `link_table` 使用 `+record-get --record-id <rec...>` 或裁剪后的 `+record-list` 读取显示字段。 |
-| 建立映射 | 形成 `关联record_id -> 显示字段值` 映射，再回填当前表结果。 |
-| 多值处理 | 多个关联值保持原顺序；可去重批量读取，但回答时按原单元格顺序输出。 |
-
-禁止事项：
-
-- 不要把 link 单元格里的 `record_id` 当作最终答案。
-- 不要用 `+record-search` 搜索 link `record_id` 来查关联记录。
-- 不要凭关联 `record_id` 猜名称、负责人、门店等显示值。
-- 不要只看当前表字段名推断关联表结构；跨表读取前必须拿关联表字段结构。
-
-## 7. 命令 help
-
-- `HelpFirst`: 参数、示例、JSON shape 和取值约束以 `lark-cli base +record-get --help`、`+record-search --help`、`+record-list --help` 为准。
-- `RecordSearchJson`: 构造 `+record-search --json` 前先看 `+record-search --help`，确认 `keyword/search_fields/select_fields/view_id/offset/limit` 的结构和约束。
-- `RecordListProjection`: 构造 `+record-list` 前先看 `+record-list --help`，确认 `--field-id`、`--view-id`、`--offset`、`--limit` 的语义。

+# im +flag-cancel
+
+> **Prerequisite:** Read [`../lark-shared/SKILL.md`](../../lark-shared/SKILL.md) for authentication, global parameters, and security rules.
+
+This skill maps to shortcut: `lark-cli im +flag-cancel`. Underlying API: `POST /open-apis/im/v1/flags/cancel`.
+
+## Double-Cancel Behavior (Important)
+
+A message can have flags on both layers simultaneously:
+- Message layer: `(default, message)`
+- Feed layer: `(thread, feed)` or `(msg_thread, feed)` depending on chat type
+
+**When no `--flag-type` is specified, the shortcut performs double-cancel**: removes both message layer and feed layer flags. The server handles cancel requests for non-existent flags idempotently, so this is safe.
+
+**Feed layer item_type is determined by chat_mode**:
+- Topic-style chat (`chat_mode=topic`) → `item_type=thread`
+- Regular chat (`chat_mode=group`) → `item_type=msg_thread`
+
+## Commands
+
+```bash
+# Double-cancel both layers (recommended default)
+lark-cli im +flag-cancel --as user --message-id om_xxx
+
+# Only cancel message layer
+lark-cli im +flag-cancel --as user --message-id om_xxx --flag-type message
+
+# Only cancel feed layer (need to specify item-type)
+lark-cli im +flag-cancel --as user --message-id om_xxx --item-type thread --flag-type feed
+
+# Preview request
+lark-cli im +flag-cancel --as user --message-id om_xxx --dry-run
+```
+
+## Parameters
+
+| Parameter | Required | Description |
+|------|------|------|
+| `--message-id <om_xxx>` | Required | Message ID |
+| `--flag-type <name>` | No | `message` or `feed`; **when omitted, double-cancels both layers** |
+| `--item-type <name>` | No | `default\|thread\|msg_thread`; required when `--flag-type feed` |
+| `--as user` | Required | Currently only supports user identity |
+
+## Idempotency
+
+The server doesn't return an error for cancel requests when the flag doesn't exist, so repeated `+cancel` calls are idempotent.
+
+## Permissions
+
+- Required scopes: `im:feed.flag:write`, `im:message.group_msg:get_as_user`, `im:message.p2p_msg:get_as_user`, `im:chat:read`
+- The message/chat read scopes are used by the default double-cancel path to auto-detect the feed-layer item type.
+
+## Note
+
+- **Do not call +flag-list for verification**: If the cancel API returns success, the flag is removed. Calling +flag-list to verify is expensive (requires full pagination) and unnecessary.
+
+## Finding Message ID Efficiently
+
+If you have message content but not the message ID:
+
+1. **Use `+messages-search`** to find the message by content, then extract `message_id` from the result
+2. **Do NOT use `+flag-list`** to find the message — it requires full pagination and is very inefficient
+
+```bash
+# Search by message content to find message_id
+lark-cli im +messages-search --as user --query "message content here" -q '.data.items[0].message_id'

+# im +flag-create

+> **Prerequisite:** Read [`../lark-shared/SKILL.md`](../../lark-shared/SKILL.md) for authentication, global parameters, and security rules.
+
+This skill maps to shortcut: `lark-cli im +flag-create`. Underlying API: `POST /open-apis/im/v1/flags`.
+
+## Default Behavior
+
+- **Message-layer flag** (default): `item_type=default, flag_type=message`
+- **Feed-layer flag**: Use `--flag-type feed` — automatically detects chat type to determine `item_type`:
+  - Topic-style chat (`chat_mode=topic`) → `item_type=thread`
+  - Regular chat (`chat_mode=group`) → `item_type=msg_thread`
+
+## Commands
+
+```bash
+# Flag a message (default: message-layer)
+lark-cli im +flag-create --as user --message-id om_xxx
+
+# Create feed-layer flag (auto-detects chat type)
+lark-cli im +flag-create --as user --message-id om_xxx --flag-type feed
+
+# Explicit item-type override (rarely needed)
+lark-cli im +flag-create --as user --message-id om_xxx --item-type thread --flag-type feed
+
+# Preview request (dry-run, doesn't send)
+lark-cli im +flag-create --as user --message-id om_xxx --dry-run
+```
+
+## Parameters
+
+| Parameter | Required | Description |
+|------|------|------|
+| `--message-id <om_xxx>` | Required | Message ID |
+| `--flag-type <name>` | No | `message` (default) or `feed` |
+| `--item-type <name>` | No | Override auto-detection: `default\|thread\|msg_thread` (rarely needed) |
+| `--as user` | Required | Currently only supports user identity |
+
+## Valid Combinations
+
+The server only accepts these `(item_type, flag_type)` pairs:
+
+- `(default, message)` — regular message flag
+- `(thread, feed)` — feed flag in topic-style chat
+- `(msg_thread, feed)` — feed flag in regular chat
+
+## Permissions
+
+- Required scopes: `im:feed.flag:write`, `im:message.group_msg:get_as_user`, `im:message.p2p_msg:get_as_user`, `im:chat:read`
+- The message/chat read scopes are used when `--flag-type feed` is used without explicit `--item-type` so the CLI can auto-detect chat type.
+- If missing, CLI will prompt with `lark-cli auth login --scope "..."`
+
+## Note
+
+- **Do not call +flag-list for verification**: If the create API returns success, the flag is created. Calling +flag-list to verify is expensive (requires full pagination) and unnecessary.
+

+If you have message content but not the message ID:

+1. **Use `+messages-search`** to find the message by content, then extract `message_id` from the result

+## Sorting Rules (Important)
+
+The API returns data sorted by `update_time` in **ascending order**, meaning **oldest first, newest last**. When `has_more=true`, you cannot simply take the first page's items as the latest flags — you must paginate through all pages and take the last item on the last page as the newest.

+```
+
+## Parameters
+
+| Parameter | Default | Description |
+|------|------|------|
+| `--page-size <n>` | 50 | Range 1-50 (server max is 50) |
+| `--page-token <token>` | empty | Pagination token from previous page; empty string must still be provided |
+| `--page-all` | false | Auto-paginate to fetch all pages and merge results |
+| `--page-limit <n>` | 20 | Max pages in `--page-all` mode (max 1000) |
+| `--enrich-feed-thread` | true | Auto-enrich feed-layer thread entries with message content (calls `im.messages.mget`) |
+| `--as user` | Required | Currently only supports user identity |
+
+## Response Structure
+
+The response has `data` as the main body, with fields described below:
+
+| Field | Type | Description |
+|------|------|------|
+| `flag_items` | array | List of currently existing (not canceled) flags, sorted by `update_time` ascending |
+| `delete_flag_items` | array | List of previously canceled flags, sorted by `update_time` ascending |
+| `messages` | array | Message content inlined by the server for `(default, message)` type flags |
+| `has_more` | boolean | Whether there's a next page |
+| `page_token` | string | Pagination token for the next page |
+
+Note: `(thread, feed)` / `(msg_thread, feed)` entries are automatically enriched via `mget` by the shortcut, and written to the corresponding entry's `message` field.
+
+## Limitations
+
+- **delete_flag_items are not enriched**: Message content is only fetched for active flags (`flag_items`), not canceled flags (`delete_flag_items`). If you need message content for a canceled flag, query the message separately using `+messages-mget --message-ids <item_id>`.
+
+## Response Example (Sanitized)
+
+```json
+{
+  "data": {
+    "delete_flag_items": [
+      {
+        "create_time": "xxx",
+        "flag_type": "xxx",
+        "item_id": "xxx",
+        "item_type": "xxx",
+        "update_time": "xxx"
+      }
+    ],
+    "flag_items": [
+      {
+        "create_time": "xxx",
+        "flag_type": "xxx",
+        "item_id": "xxx",
+        "item_type": "xxx",
+        "update_time": "xxx"
+      }
+    ],
+    "has_more": false,
+    "messages": [],
+    "page_token": "xxx"
+  }
+}
+```
+
+## Permissions
+
+- Base scope: `im:feed.flag:read`
+- Additional scopes only when `--enrich-feed-thread=true` needs to fetch missing message content: `im:message.group_msg:get_as_user`, `im:message.p2p_msg:get_as_user`

+
+## 核心场景
+
+### 1. 加入正在进行的会议（写操作）
+
+1. 只有用户明确表达"让 Agent **真实入会**"（参会机器人、会中助手、代为旁听、代参会）时才用 `+meeting-join`。只是查数据不要入会。
+2. `+meeting-join --meeting-number` 只接受 **9 位纯数字**会议号，不是会议链接整串、也不是 `meeting_id`。
+3. 返回体中的 `meeting.id` **必须立刻记录**——后续 `+meeting-events` / `+meeting-leave` 都靠它，**不能用 9 位会议号替代**。
+4. 入会对所有参会人可见，执行前核实 9 位会议号来源，避免误入错会。
+5. 仅支持 `user` 身份，需提前 `lark-cli auth login`。
+6. 若入会失败，优先查看 `+meeting-join` reference 的错误排查段落，重点确认会议号、密码、会议状态、等候室 / 审批以及会议是否禁止当前身份加入。
+
+### 2. 感知会中事件（读操作）
+
+1. 用户要看"会议里正在发生什么"（参会人加入/离开、聊天、转写、屏幕共享）时，用 `+meeting-events`。
+2. 输入是 **`meeting_id`**（长数字 ID），不是 9 位会议号。
+3. Bot 必须**真实参会过**（先 `+meeting-join`），否则事件流通常不可见。具体的状态边界、结束后宽限窗口与错误码（如 `10005 / 20001 / 20002`）请查看 `+meeting-events` reference。
+4. **不能做会后复盘**，**不能替代参会人快照查询**。如果会议已结束：
+   - 想拿纪要文档或逐字稿文档 token：用 `lark-cli vc +notes --meeting-ids <meeting.id>`
+   - 想拿 AI 产物（summary / todos / chapters）或导出逐字稿文件：先用 `lark-cli vc +recording --meeting-ids <meeting.id>` 拿 `minute_token`，再用 `lark-cli vc +notes --minute-tokens <minute_token>`
+   - 想看参会人快照：用 `vc meeting get --with-participants`（见 [`lark-vc`](../lark-vc/SKILL.md)）
+5. **默认必须使用** **`--page-all`**，除非用户明确要求“只查一页”，或确实需要控制返回体大小。
+6. 输出格式默认优先 `--format pretty`（时间线更易读）；只有在需要完整保留原始消息流与结构化字段时，才使用 `--format json`。
+7. **必须识别分页信号**：只要响应里出现 `has_more=true`、pretty 里的 `more available`，或返回了非空 `page_token`，就不能把当前结果当作完整事件流；默认应继续分页，或明确告诉用户当前只是部分结果。
+8. 保留响应里的 `page_token`，下次增量拉取直接续，不要从头再拉。
+9. **只要你是基于** **`+meeting-events`** **来回答一场正在进行中的会议内容，就不能直接复用旧结果。** 无论用户是在问“现在/刚刚/最新”的状态，还是让你“总结一下这个会议讲什么”，都必须先重新拉一次当前事件流，确认拿到的是最新信息，再基于最新结果回答。只有在用户明确要求基于某次历史快照继续分析时，才可以复用旧结果。
+
+### 3. 离开会议（写操作）
+
+1. 任务完成、或用户要求结束时，用 `+meeting-leave --meeting-id <从 +meeting-join 拿到的 meeting.id>`。
+2. `--meeting-id` **必须**是 `+meeting-join` 返回的长数字 `meeting.id`，**不接受 9 位会议号**。
+3. 离会**立即生效**，机器人从会议的参会人列表中消失，对其他参会人可见；若需要重新入会，再跑一次 `+meeting-join` 即可（非真正"不可逆"）。
+4. 仅支持 `user` 身份。
+
+### 4. Agent 参会最小闭环示范
+
+```bash
+# 1. 入会，捕获 meeting.id
+JOIN=$(lark-cli vc +meeting-join --meeting-number 123456789 --format json)
+MID=$(echo "$JOIN" | jq -r '.data.meeting.id')
+
+# 2. 会中轮询事件
+#    默认用 --page-all 拉全当前可见事件；下次增量优先复用 page_token
+#    典型间隔 10-30 秒
+lark-cli vc +meeting-events --meeting-id "$MID" --page-all --format pretty
+
+# 3. 任务完成或用户要求结束时离会
+lark-cli vc +meeting-leave --meeting-id "$MID"
+
+# 4. 会后可选：取纪要 / 逐字稿（跨到 lark-vc）
+lark-cli vc +notes --meeting-ids "$MID"
+```

+## 参数
+
+| 参数 | 必填 | 说明 |
+|------|------|------|
+| `--meeting-id <id>` | 是 | 会议 ID（长数字 ID，不是 9 位会议号） |
+| `--start <time>` | 否 | 起始时间，支持 ISO 8601 / `YYYY-MM-DD` / Unix 秒 |
+| `--end <time>` | 否 | 结束时间，支持 ISO 8601 / `YYYY-MM-DD` / Unix 秒 |
+| `--page-token <token>` | 否 | 从指定分页游标继续拉取下一页 |
+| `--page-size <n>` | 否 | 单页模式每页大小。CLI 会自动夹紧到 `20-100`；传 `--page-all` 时固定使用 `100` |
+| `--page-all` | 否 | 自动分页，直到没有更多页面为止（内部有安全上限） |
+| `--format <fmt>` | 否 | 输出格式：json (CLI 默认) / pretty（本 skill 推荐默认） / table / ndjson / csv |
+| `--dry-run` | 否 | 预览 API 调用，不执行 |
+
+## 核心约束
+
+### 1. 输入必须是 meeting_id，不是 9 位会议号
+
+`--meeting-id` 必须是会议的长数字 ID。它通常来自：
+- `+meeting-join` 返回体中的 `meeting.id`
+- `+search` 结果中的 `id`
+
+**不要**把 9 位会议号（`--meeting-number`）传给这个命令。
+
+### 2. 仅支持 user 身份
+
+该命令仅支持 `user` 身份。
+
+### 3. bot 必须在会中，或在会议结束后的 5 分钟宽限窗口内曾经在会中
+
+这是查询“bot 在会中观察到的事件”的接口。若 bot 已离会、未入会、或会议已经无法再判断 bot 身份，后端通常会报：
+- `bot is not in meeting, no permission`
+
+因此，最稳妥的调用顺序通常是：
+
+```bash
+# 先入会
+lark-cli vc +meeting-join --meeting-number 123456789
+
+# 记录返回的 meeting.id
+
+# 再查询事件
+lark-cli vc +meeting-events --meeting-id <meeting.id>
+```
+
+更精确地说，后端当前的判断规则是：
+
+- **会议进行中**：要求 bot **当前仍在会中**
+- **会议已结束后的 5 分钟内**：只要 bot **曾经在这场会中出现过**，仍可拉取事件
+- **会议结束超过 5 分钟**：按会议结束处理，通常不再返回事件流
+- **bot 从未真实入会过**：即使会议仍在进行或刚结束，也会返回 `10005 bot is not in meeting`
+
+### 4. 自动分页规则
+
+- **先分清两层默认值**：
+  - shortcut 本身：不传 `--page-all` 时，只查 1 页。
+  - 本 skill 的默认策略：除非用户明确要求只看一页，或你确实需要控制返回体大小，否则默认**必须主动带 `--page-all`**，把当前可见事件尽量一次拉全。
+- 传 `--page-all`：开启自动分页，直到没有更多页面为止。
+- `--page-all` 时，CLI 固定使用最大 `page_size=100`。
+
+执行准则：
+
+- **默认命令模板**：`lark-cli vc +meeting-events --meeting-id <meeting.id> --page-all --format pretty`
+- 如果你发现自己执行成了不带 `--page-all` 的单页查询，而响应里又出现 `has_more=true` / `more available` / 非空 `page_token`，应立刻意识到这只是部分结果。
+- 遇到上述情况，默认补救方式是继续使用返回的 `page_token` 续拉，例如：`lark-cli vc +meeting-events --meeting-id <meeting.id> --page-token <returned_page_token> --page-all --format pretty`
+- 只有在用户明确要求“就看第一页”“先不要翻页”时，才不要默认带 `--page-all`
+- 只要你是基于 `+meeting-events` 来回答一场**正在进行中的会议内容**，就不能直接复用上一次查询结果。无论用户是在问“现在是谁在说话”“刚刚发生了什么”“最新事件有哪些”，还是让你“总结一下这个会议讲什么”，都必须先重新执行一次 `+meeting-events`，确认拿到的是最新事件流，再回答用户。只有在用户明确要求基于某次历史快照继续分析时，才可以复用旧结果。
+
+### 5. pretty / json 输出差异
+
+- `--format pretty`：输出会议主题、会议时间和逐条时间线，适合快速理解“发生了什么”，也是本 skill 的默认推荐格式。
+- `--format json`：保留完整原始 `events[]` 结构——参会人 open_id、聊天原文、share_doc、分页字段都在原始响应里，适合提取字段、联动其他命令或做进一步程序处理。
+
+**选型原则**：只要目标是告诉用户“发生了什么”，默认就用 `--page-all --format pretty`；只有在需要完整原始消息流和结构化字段时，才改用 `json`。
+
+> **注意**：pretty 输出中的正文文本会做单行转义，真实换行会显示为 `\n`，避免打乱时间线布局。
+
+### 6. 内容理解模式：共享文档不能只看标题
+
+当用户意图是：
+
+- “总结这个会议”
+- “这个会议讲了什么”
+- “有哪些结论 / 待办 / 关键讨论”
+- “共享文档里在讲什么”
+
+不要只基于事件时间线直接回答。此时 `+meeting-events` 只是**线索发现器**，不是最终信息源。
+
+执行准则：
+
+- 这类问题默认先用 `lark-cli vc +meeting-events --meeting-id <meeting.id> --page-all --format json` 拉取最新事件流。
+- 如果事件中出现共享文档线索，例如：
+  - `magic_share_started`
+  - `share_doc.title`
+  - `share_doc.url`
+- 必须继续读取共享文档内容，再生成总结，不能只根据“开始共享了某文档”这条事件和文档标题来概括会议内容。
+- 若存在多个共享文档，优先读取**最近一次共享**的文档。
+- 若文档读取失败，必须明确说明“以下总结仅基于会中事件流，未成功读取共享文档内容”。
+
+### 7. 关于 `page_token` 的返回与续拉
+
+- 不管这次是只查 1 页，还是通过 `--page-all` 已经把当前可见事件都拿完，都应把最后拿到的 `page_token` 一并保留下来并返回给用户。
+- 只要响应里出现 `has_more=true`、pretty 里出现 `more available`，或返回了非空 `page_token`，就必须先判断当前结果是否完整；默认情况下，这意味着你还需要继续分页。
+- 如果没有使用 `--page-all`，但出现了上述分页信号，默认应继续用返回的 `page_token` 拉下一页，而不是直接结束。只有在用户明确不要继续翻页时，才可以停止并明确说明当前结果不完整。
+- 下次继续“查新增事件”时，应优先复用上一次保存的 `page_token`，而不是从头全量再拉一次。
+- 只有在用户明确要求“从头回放全部事件”时，才忽略历史 `page_token`，重新从第一页开始。
+- 但如果用户要你回答的是**当前这场会正在讲什么**，而不是“上一次之后新增了什么”，也要先做一次新的事件查询，再决定是否需要基于旧 `page_token` 继续补拉。
+
+## 返回结构
+
+常见顶层字段：
+
+| 字段 | 说明 |
+|------|------|
+| `events` | 事件列表 |
+| `has_more` | 是否还有下一页 |
+| `page_token` | 下一页游标 |
+
+事件 `event_type` 常见类型：
+
+| event_type | 含义 |
+|-----------|------|
+| `participant_joined` | 有参会人加入会议 |
+| `participant_left` | 有参会人离开会议 |
+| `chat_received` | 收到会中聊天消息 |
+| `transcript_received` | 收到转写文本 |
+| `magic_share_started` | 开始共享内容 / 文档 |
+| `magic_share_ended` | 结束共享 |
+
+## pretty 输出示例
+
+```text
+会议主题：张三的视频会议
+会议时间：2026-04-17 15:28:52（进行中）
+
+[00:00:33] 明日之虾BOE(ou_xxx) 加入了会议

+           URL: https://...
+[00:01:32] 张三(ou_xxx): [reaction] JIAYI
+```
+
+## 如何获取输入参数
+
+| 输入参数 | 获取方式 |
+|---------|---------|
+| `meeting-id` | `+meeting-join` 返回的 `meeting.id`；或 `+search` 结果中的 `id` |
+| `start` / `end` | 用户给出的时间范围；如未给出则默认取全量可见事件 |
+| `page-token` | 上一页或上一次查询结果中保存的 `page_token`；建议持久化保存，便于下次继续拉取新增事件 |
+
+## Agent 组合场景
+
+### 场景 1：入会后查看会中发生了什么
+
+```bash
+# 第 1 步：加入会议，记录返回的 meeting.id
+lark-cli vc +meeting-join --meeting-number 123456789
+
+# 第 2 步：查询事件流
+lark-cli vc +meeting-events --meeting-id <meeting.id> --page-all --format pretty
+```
+
+### 场景 2：过滤某段时间内的事件
+
+```bash
+lark-cli vc +meeting-events \
+  --meeting-id <meeting.id> \
+  --start 2026-04-17T15:00:00+08:00 \
+  --end 2026-04-17T16:00:00+08:00 \
+  --page-all \
+  --format pretty
+```
+
+### 场景 3：基于上一次的 `page_token` 继续查新增事件
+
+```bash
+# 上一次查询结束后，保留最后返回的 page_token
+# 这次直接从该游标继续拉新增事件
+lark-cli vc +meeting-events \
+  --meeting-id <meeting.id> \
+  --page-token <last_page_token> \
+  --page-all \
+  --format pretty
+```
+
+适用规则：
+
+- 当用户说“继续看新事件”“看上次之后新增了什么”时，优先使用上一次保存的 `page_token`。
+- 如果这次返回里仍有 `has_more=true`、pretty 里出现 `more available`，或又返回了新的 `page_token`，说明新增事件还没拉完，应继续分页，而不是把当前页误当成完整增量结果。
+- 只有在用户明确要求“从头回放全部事件”时，才忽略已有 `page_token`，重新从第一页开始。
+
+## 常见错误与排查
+
+| 错误现象 | 根本原因 | 解决方案 |
+|---------|---------|---------|
+| `--meeting-id is required` | 未传入 `--meeting-id` | 传入长数字 `meeting.id` |
+| `10005 bot is not in meeting` | bot 从未真实入会该会议；或会议已结束但 bot 从未在会中出现过 | 先 `+meeting-join --meeting-number <9位号>` 真实入会再查；如果会议已经结束且当时 bot 没进过会，本接口也拉不到数据。**如果只是想看参会人快照，改用 `lark-cli vc meeting get --params '{"meeting_id":"<meeting.id>"}' --with-participants`**（不依赖 bot 身份参会） |
+| `20001 meeting_status_MEETING_END` | 会议已结束且已超出后端允许的 5 分钟宽限窗口 | 本接口不再适合继续拉取事件。若要拿纪要文档或逐字稿 token，用 `lark-cli vc +notes --meeting-ids <meeting.id>`；若要拿 AI 产物（summary / todos / chapters）或导出逐字稿文件，先用 `lark-cli vc +recording --meeting-ids <meeting.id>` 拿 `minute_token`，再用 `lark-cli vc +notes --minute-tokens <minute_token>`；参会人请用 `lark-cli vc meeting get --params '{"meeting_id":"<meeting.id>"}' --with-participants` |
+| `20002 meeting not exist` | `meeting_id` 错误，或会议实例当前已不可获取（常见于把 9 位会议号当 meeting_id 传） | 确认传入的是长数字 `meeting_id`，不是 9 位会议号 |
+| `HTTP 404` / `HTTP 500` | 服务端当前无法找到或处理该会议实例 | 换一个正在进行且 bot 可见的 meeting_id，或排查后端问题 |
+
+## 提示
+
+- 这是**会中事件流**查询，不适合拿来搜历史会议记录；搜历史会议请用 `+search`。
+- 如果会议已经结束，不要卡在 `+meeting-events`：  
+  - 想拿纪要文档或逐字稿 token：用 `lark-cli vc +notes --meeting-ids <meeting.id>`
+  - 想拿 AI 产物（summary / todos / chapters）或导出逐字稿文件：先用 `lark-cli vc +recording --meeting-ids <meeting.id>` 拿 `minute_token`，再用 `lark-cli vc +notes --minute-tokens <minute_token>`
+- 事件列表是否完整，取决于 bot 何时入会、何时离会，以及后端当前可见的会中事件范围。对于已结束会议，通常只在**结束后 5 分钟内**、且 bot **曾经在会中**时还能继续拉到事件。
+- 查询"谁参加过某会议"请用 `vc meeting get --params '{"meeting_id":"<id>","with_participants":true}'`——这是参会人**快照** API，不依赖 bot 是否参会，对已结束会议也可查；**不要** 用 `+meeting-events` 做参会人查询。

+# vc +meeting-join
+
+> **前置条件：** 先阅读 [`../lark-shared/SKILL.md`](../../lark-shared/SKILL.md) 了解认证、全局参数和安全规则。
+
+通过 9 位会议号加入一场正在进行的视频会议（bot join）。这是一次**写操作**，会实际让当前身份加入会议。
+
+本 skill 对应 shortcut：`lark-cli vc +meeting-join`（调用 `POST /open-apis/vc/v1/bots/join`）。
+
+## 命令
+
+```bash
+# 仅指定会议号（无密码）
+lark-cli vc +meeting-join --meeting-number 123456789
+
+# 指定会议号 + 密码
+lark-cli vc +meeting-join --meeting-number 123456789 --password 8888

+
+# 预览 API 调用（不实际加入会议）
+lark-cli vc +meeting-join --meeting-number 123456789 --dry-run
+```
+
+## 参数
+
+| 参数 | 必填 | 说明 |
+|------|------|------|
+| `--meeting-number <no>` | 是 | 会议号，必须为 **9 位纯数字** |
+| `--password <pw>` | 否 | 会议密码，仅在该会议设置了入会密码时传入 |
+| `--format <fmt>` | 否 | 输出格式：json (默认) / pretty / table / ndjson / csv |
+| `--dry-run` | 否 | 预览 API 调用，不执行 |
+
+## 核心约束
+
+### 1. 仅支持 user 身份
+
+该命令仅支持 `user` 身份。
+
+### 2. 会议号格式严格校验
+
+`--meeting-number` 必须是 9 位纯数字，否则本地校验直接报错：
+`--meeting-number must be exactly 9 digits`。
+
+常见错误来源：
+- 把会议链接整条粘进来（应仅取尾部的 9 位数字）
+- 把 `meeting_id`（长数字 ID）当成会议号传入（两者不是同一个东西）
+
+### 3. 会议必须已开始且允许入会
+
+- 会议必须处于**进行中**状态，bot 无法加入尚未开始或已结束的会议。
+- 若会议设置了**等候室 / 入会审批**，bot 可能需要主持人放行后才真正入会。
+- 若返回 `HTTP 403: no permission`（错误码 `121003`），不要只理解成“账号没权限”。这类报错更常见的原因是：会议参数或会控配置当前不满足入会条件，例如会议号填错、密码未传或错误、会议尚未开始、等候室 / 入会审批未放行、会议禁止外部/特定身份加入等。应先确认这些配置项，再重试。
+
+### 4. 机器人入会后对其他参会人可见
+
+这是一次真实入会操作，机器人会立即出现在参会人列表中，其他参会人可见，并产生会议日志。误入错会的社交成本高于技术成本——执行前优先确认 9 位会议号的来源（用户输入 / 会议链接末尾），不要臆造。参数格式有疑问时可用 `--dry-run` 预览请求体。
+
+## 输出结果
+
+接口返回会议基本信息，字段视具体响应而定，常见字段：
+
+| 字段 | 说明 |
+|------|------|
+| `meeting.id` | 会议 ID（可后续传给 `+meeting-leave --meeting-id`） |
+| `meeting.meeting_no` | 会议号（与入参一致） |
+| `meeting.topic` | 会议主题 |
+| `meeting.start_time` | 会议开始时间 |
+
+> **重要**：拿到 `meeting.id` 后务必保留，退出会议（`+meeting-leave`）需要使用它，而不是会议号。
+
+## 如何获取输入参数
+
+| 输入参数 | 获取方式 |
+|---------|---------|
+| `meeting-number` | 会议号由主持人分享；也可从会议链接尾部解析 9 位数字 |
+| `password` | 若会议设置了入会密码，由主持人提供 |
+
+## Agent 组合场景
+
+### 场景 1：加入会议 → 离开会议（最小闭环）
+
+```bash
+# 第 1 步：加入会议，记录返回的 meeting.id
+lark-cli vc +meeting-join --meeting-number 123456789
+
+# 第 2 步：完成任务后，使用上一步返回的 meeting.id 离开会议
+lark-cli vc +meeting-leave --meeting-id <meeting.id>
+```
+
+### 场景 2：加入会议 → 会后拉取纪要 / 录制
+
+```bash
+# 第 1 步：加入并参会
+lark-cli vc +meeting-join --meeting-number 123456789
+
+# 第 2 步：离会
+lark-cli vc +meeting-leave --meeting-id <meeting.id>
+
+# 第 3 步：会议结束后，查询录制（拿到 minute_token）
+lark-cli vc +recording --meeting-ids <meeting.id>
+
+# 第 4 步：查询会议纪要（总结 / 待办 / 章节 / 逐字稿）
+lark-cli vc +notes --meeting-ids <meeting.id>
+```
+
+## 常见错误与排查
+
+| 错误现象 | 根本原因 | 解决方案 |
+|---------|---------|---------|
+| `--meeting-number must be exactly 9 digits` | 会议号不是 9 位纯数字 | 检查是否误传了会议链接或 meeting_id |
+| 会议密码错误 | `--password` 错误或未提供 | 向主持人确认会议密码 |
+| 会议不存在 / 已结束 | 会议号错误或会议未进行中 | 确认会议正在进行中 |
+| `HTTP 403: no permission` / `121003` | 入会前置条件不满足，通常不是单纯 scope 问题 | 依次确认：1）会议允许智能体加入；2）会议号正确；3）如有密码，已正确传入 `--password`；4）会议已开始；5）等候室 / 入会审批已放行；6）会议未禁止当前身份加入（如限制外部、限制 bot、仅特定成员可入会）；确认后重试 |
+| 入会被拒绝 | 等候室 / 入会审批 / 限制外部入会 | 联系主持人放行或调整会议设置 |
+
+## 提示
+
+- 仅在 Agent 需要**真实加入**会议（例如参会机器人、会中助手）时使用；只拉取会议数据不需要入会。
+- 入会会让机器人立即出现在参会列表；若要回退，直接 `+meeting-leave` 即可。参数格式不确定时可选 `--dry-run` 预览，但不是必经步骤。
+- 执行成功后，立即记录返回的 `meeting.id`，用于后续 `+meeting-leave` / `+meeting-events`。

-- 图片必须上传到**目标画板**（`--parent-node` 设为目标画板 token），跨画板的 token 不可用

 ## Metrics
 - Denominator: 29 leaf commands
-- Covered: 2
-- Coverage: 6.9%
+- Covered: 7
+- Coverage: 24.1%
 
 ## Summary
 - TestDrive_FilesCreateFolderWorkflow: proves `drive files create_folder` in `create_folder as bot`; helper asserts the returned folder token and registers best-effort cleanup via `drive files delete`.
 - TestDrive_StatusWorkflow: proves `drive +status` against a real Drive folder. Seeds the remote side via `drive +upload` (`unchanged.txt`, `modified.txt`, `remote-only.txt`), seeds local files with the matching/diverging contents, and asserts every output bucket (`unchanged`, `modified`, `new_local`, `new_remote`) holds exactly the expected `rel_path` and `file_token`. Cleans up uploaded files and the parent folder via best-effort cleanup hooks.
+- TestDrive_DuplicateRemoteWorkflow: proves the duplicate-remote workflows against the real backend. One subtest uploads two same-name files into the same Drive folder and asserts `drive +status` and default `drive +pull` both fail with `duplicate_remote_path`, while `drive +pull --on-duplicate-remote=rename` succeeds, downloads both files, and writes a hashed renamed sibling locally. The other subtest uploads duplicate remote files, runs `drive +push --on-duplicate-remote=newest --if-exists=overwrite --delete-remote --yes`, and then re-runs `drive +status` to prove the mirror converged to a single unchanged `dup.txt`.
 - TestDrive_ApplyPermissionDryRun / TestDrive_ApplyPermissionDryRunRejectsFullAccess: dry-run coverage for `drive +apply-permission`; asserts URL→type inference for docx/sheet/slides, explicit `--type` overriding URL inference when both a recognized URL and `--type` are supplied, bare-token + explicit `--type` path, request method/URL/type-query/perm/remark body shape, optional `remark` omission when unset, and client-side rejection of `--perm full_access`. Runs without hitting the live API.
 - TestDriveExportDryRun_FileNameMetadata: dry-run coverage for `drive +export`; asserts export task request shape and local `--file-name` / `--output-dir` metadata without calling live APIs.
+- TestDrive_PullDryRun / TestDrive_PullDryRunAcceptsDuplicateRemoteStrategies: dry-run coverage for `drive +pull`; asserts the list-files request shape, Validate-stage safety guards, and acceptance of `--on-duplicate-remote=rename|newest|oldest` by the real CLI binary.
+- TestDrive_PushDryRun / TestDrive_PushDryRunAcceptsDuplicateRemoteStrategies: dry-run coverage for `drive +push`; asserts the list-files request shape, Validate-stage safety guards, conditional delete preflight, and acceptance of `--on-duplicate-remote=newest|oldest` by the real CLI binary.
 - Cleanup note: `drive files delete` is only exercised in cleanup and is intentionally left uncovered.
-- Blocked area: live upload, live export, comment, permission, subscription, and reply flows still need deterministic remote fixtures and filesystem setup.
-- Dry-run note: `drive_upload_dryrun_test.go::TestDriveUploadDryRun_WikiTarget` covers the wiki-target request shape for `drive +upload`, but there is still no live upload workflow coverage.
+- Blocked area: live export, comment, permission, subscription, and reply flows still need deterministic remote fixtures and filesystem setup.
+- Dry-run note: `drive_upload_dryrun_test.go::TestDriveUploadDryRun_WikiTarget` covers the wiki-target request shape for `drive +upload`; live duplicate/status workflows also use real `+upload` to seed remote fixtures.
