 - `drive +add-comment` 的 `--content` 需要传 `reply_elements` JSON 数组字符串，例如 `--content '[{"type":"text","text":"正文"}]'`。
 - 如果 wiki 解析后不是 `doc`/`docx`，不要用 `+add-comment`。
 - 如果需要更底层地直接调用评论 V2 协议，再走原生 API：先执行 `lark-cli schema drive.file.comments.create_v2`，再执行 `lark-cli drive file.comments create_v2 ...`。全文评论省略 `anchor`，局部评论传 `anchor.block_id`。

+- **第一步永远是判断任务类型：新建日程，还是编辑已有日程。** 不要把“预约/查会议室”默认等同于“新建”。
+- **编辑已有日程时，必须先定位目标日程或实例的 `event_id`。** 用户一旦给出了既有日程锚点（标题、时间段、`这个日程`、`这场会`）并表达修改动作（加人、删人、改时间、换会议室等），默认走编辑流。
 - **默认做智能助理，不做表单填写机。** 能根据上下文补全的默认值就直接补全，避免把用户带入表单式问答。
-- **先补默认值，再判断时间是否明确。** 默认值包括标题、参会人、时长，以及在“完全无时间信息”时的默认时间范围。
+- **新建流先补默认值，编辑流先继承已定位日程信息。** 默认值包括标题、参会人、时长，以及在“完全无时间信息”时的默认时间范围；编辑流则优先复用已定位日程的标题、时间、已有参与人和会议室信息作为基线。
 - **只有三类场景才主动追问用户**：存在时间冲突、搜索结果无法唯一确定、时间语义本身有歧义。
+- **编辑流的时间基准必须明确。** 如果编辑时不改时间，则后续会议室搜索必须基于已定位日程的原始起止时间；如果既改时间又加会议室，必须先确定最终时间，再基于该时间搜索会议室。
+- **编辑流中“新增会议室”默认是增量语义。** 如果用户说的是“加会议室/再加一个会议室”，最终 `+update` 只做 `add`，默认保留已有会议室；只有在用户明确说“更换会议室/移除会议室”时，才执行旧会议室删除。
 - **明确时间**：若需要会议室，先 `+room-find`；再 `+freebusy` 判断参会人忙闲；有冲突时先说明冲突，再让用户决定继续当前时间还是改走 `+suggestion`。

+| `--description <text>` | 否 | 新日程描述。目前 API 方式不支持编辑富文本描述；如果日程描述通过客户端编辑为富文本内容，则使用 API 更新描述会导致富文本格式丢失。仅在显式传入 `--description` 时更新；若传空字符串，会把描述清空 |
+| `--start <time>` | 否 | 新开始时间（ISO 8601，如 `2026-03-12T14:00+08:00`）。更新日程时间时必须同时传 `--end` |
+| `--end <time>` | 否 | 新结束时间（ISO 8601）。更新日程时间时必须同时传 `--start` |
+| `--rrule <rrule>` | 否 | 新重复规则（RFC5545）。**不要使用 COUNT；如需限制次数，推算后转为 UNTIL** |
+| `--add-attendee-ids <id_list>` | 否 | 增量添加参会人/会议室，逗号分隔。支持用户 `ou_`、群组 `oc_`、会议室 `omm_` |
+| `--remove-attendee-ids <id_list>` | 否 | 增量移除参会人/会议室，逗号分隔。支持用户 `ou_`、群组 `oc_`、会议室 `omm_` |
+| `--notify` | 否 | 是否发送更新通知，默认 `true`。可用 `--notify=false` 静默更新 |
+| `--dry-run` | 否 | 预览 API 调用，不执行 |
+
+至少需要提供一个动作：`--summary`、`--description`、`--start/--end`、`--rrule`、`--add-attendee-ids` 或 `--remove-attendee-ids`。
+
+## 使用规则
+
+- `--add-attendee-ids` 是**增量添加**，不是替换最终参与人列表。不要用它表达“只保留这些人”。
+- 对 `--summary`、`--description`，CLI 以“是否显式传入该 flag”判断是否更新，而不是以“值是否为空”判断；如果显式传入空字符串，会把对应字段清空。
+- 只想增删参会人或会议室时，不需要同时传 `--summary`、`--start`、`--end` 等日程字段。
+- 只想修改标题、描述、时间或重复规则时，不需要同时传 `--add-attendee-ids` 或 `--remove-attendee-ids`。
+- 如需替换某个参与人、群组或会议室，使用 `--remove-attendee-ids <旧ID>` + `--add-attendee-ids <新ID>`。
+- 会议室是 resource attendee，必须使用 `omm_` ID 添加到参会人列表，不能脱离日程单独预定。
+- 更新重复性日程的某一次实例时，必须先通过 `+agenda`、`events search_event` 或实例视图定位该实例的 `event_id`。
+- 如果需要验证更新结果，等待至少 2 秒后再查询，避免同步延迟导致读到旧数据。
+- 当同一次命令组合多个动作时，执行顺序为“日程字段 -> 移除参会人 -> 添加参会人”。若中途失败，不会自动回滚已成功步骤；错误信息会说明已完成的步骤。
+
+## 高级用法（完整 API 命令）
+
+`+update` 只覆盖标题、描述、时间、重复规则，以及参会人/会议室的增量添加或移除。
+
+如需更新 `location`（地理位置，不含会议室位置）、`visibility`（日程公开范围）、自定义 `reminders`（提醒设置）、自定义 `attendee_ability`（参与人权限）、自定义 `free_busy_status`（日程忙闲状态）、`color`（颜色）、附件、视频会议信息、全天日程，或在新增参会人时配置可选参加状态 等高级参数，请改用完整的 API 命令。建议先通过 `lark-cli schema calendar.events.patch`、`lark-cli schema calendar.event.attendees.create`、`lark-cli schema calendar.event.attendees.batch_delete` 查看完整参数定义。
+
+> 完整 API 命令的时间参数是 **Unix 秒字符串**（非 ISO 8601）。
+
+## 预约/改约会议室场景
+
+如果用户要“改会议时间”“换会议室”“给现有日程加会议室”，必须先阅读 [`lark-calendar-schedule-meeting.md`](lark-calendar-schedule-meeting.md) 并按其中工作流处理：
+
+- 明确时间且需要会议室：先 `+room-find`，再按需 `+freebusy`，用户确认后再 `+update`。
+- 模糊时间或无时间：先 `+suggestion`，如需会议室再批量 `+room-find`，用户确认后再 `+update`。
+- 面临时间方案或会议室方案选择时，必须先展示候选方案并等待用户确认。
+
+## 参会人类型
+
+| 前缀 | 类型 | 说明 |
+|------|------|------|
+| `ou_` | user | 飞书用户 open_id |
+| `oc_` | chat | 飞书群组 |
+| `omm_` | resource | 会议室 |
+
+> [!CAUTION]
+> 这是**写入操作**。执行前必须确认用户意图，特别是移除参会人/会议室或移动会议时间。

-**CRITICAL — 开始前 MUST 先用 Read 工具读取 [`../lark-shared/SKILL.md`](../lark-shared/SKILL.md)，其中包含认证、权限处理**
-
-## 核心概念
-
-### 文档类型与 Token
-
-飞书开放平台中，不同类型的文档有不同的 URL 格式和 Token 处理方式。在进行文档操作（如添加评论、下载文件等）时，必须先获取正确的 `file_token`。
-
-### 文档 URL 格式与 Token 处理
-
-| URL 格式 | 示例                                                      | Token 类型 | 处理方式 |
-|----------|---------------------------------------------------------|-----------|----------|
-| `/docx/` | `https://example.larksuite.com/docx/doxcnxxxxxxxxx`    | `file_token` | URL 路径中的 token 直接作为 `file_token` 使用 |
-| `/doc/` | `https://example.larksuite.com/doc/doccnxxxxxxxxx`     | `file_token` | URL 路径中的 token 直接作为 `file_token` 使用 |
-| `/wiki/` | `https://example.larksuite.com/wiki/wikcnxxxxxxxxx`    | `wiki_token` | ⚠️ **不能直接使用**，需要先查询获取真实的 `obj_token` |
-| `/sheets/` | `https://example.larksuite.com/sheets/shtcnxxxxxxxxx`  | `file_token` | URL 路径中的 token 直接作为 `file_token` 使用 |
-| `/drive/folder/` | `https://example.larksuite.com/drive/folder/fldcnxxxx` | `folder_token` | URL 路径中的 token 作为文件夹 token 使用 |
-
-### Wiki 链接特殊处理（关键！）
-
-知识库链接（`/wiki/TOKEN`）背后可能是云文档、电子表格、多维表格等不同类型的文档。**不能直接假设 URL 中的 token 就是 file_token**，必须先查询实际类型和真实 token。
-
-#### 处理流程
-
-1. **使用 `wiki.spaces.get_node` 查询节点信息**
-   ```bash
-   lark-cli wiki spaces get_node --params '{"token":"wiki_token"}'
-   ```
-
-2. **从返回结果中提取关键信息**
-   - `node.obj_type`：文档类型（docx/doc/sheet/bitable/slides/file/mindnote）
-   - `node.obj_token`：**真实的文档 token**（用于后续操作）
-   - `node.title`：文档标题
-
-3. **根据 `obj_type` 使用对应的 API**
-
-   | obj_type | 说明 | 使用的 API |
-   |----------|------|-----------|
-   | `docx` | 新版云文档 | `drive file.comments.*`、`docx.*` |
-   | `doc` | 旧版云文档 | `drive file.comments.*` |
-   | `sheet` | 电子表格 | `sheets.*` |
-   | `bitable` | 多维表格 | `bitable.*` |
-   | `slides` | 幻灯片 | `drive.*` |
-   | `file` | 文件 | `drive.*` |
-   | `mindnote` | 思维导图 | `drive.*` |
-
-#### 查询示例
+> **⚠️ API 版本：本 skill 使用 v2 API。所有 `docs +create`、`docs +fetch`、`docs +update` 命令必须携带 `--api-version v2`。**
 
 ```bash
-# 查询 wiki 节点
-lark-cli wiki spaces get_node --params '{"token":"wiki_token"}'
+# 常用示例
+lark-cli docs +fetch  --api-version v2 --doc "文档URL或token"
+lark-cli docs +create --api-version v2 --content '<title>标题</title><p>内容</p>'
+lark-cli docs +update --api-version v2 --doc "文档URL或token" --command append --content '<p>内容</p>'
 ```
 
-返回结果示例：
-```json
-{
-   "node": {
-      "obj_type": "docx",
-      "obj_token": "xxxx",
-      "title": "标题",
-      "node_type": "origin",
-      "space_id": "12345678910"
-   }
-}
-```
+## 前置条件 — 执行操作前必读
 
-### 资源关系
+**CRITICAL — 执行对应操作前，MUST 先用 Read 工具读取以下文件，缺一不可：**
+1. [`../lark-shared/SKILL.md`](../lark-shared/SKILL.md) — 认证、权限处理、全局参数（所有操作通用）

+3. **创建或编辑文档内容** → 必读 [`lark-doc-xml.md`](references/lark-doc-xml.md)（XML 语法规则，仅当用户明确要求 Markdown 时改读 [`lark-doc-md.md`](references/lark-doc-md.md)）；从零创建时加读 [`lark-doc-create-workflow.md`](references/style/lark-doc-create-workflow.md)；编辑已有文档时加读 [`lark-doc-update-workflow.md`](references/style/lark-doc-update-workflow.md)

-## 绘图需求识别与挖掘
-
-用户很少主动提"画板"——**默认**使用飞书画板承载图表，命中以下任一信号即触发：
-- 用户提到图表类型：架构图、流程图、时序图、组织图、路线图、对比图、鱼骨图、飞轮图、思维导图等
-- 用户表达可视化意图：画一下、梳理关系、画个流程、给我一个图、方便汇报等
-- 文档主题涉及结构关系、流程走向、时间线、数据对比
-
-以下场景不加图：用户明确拒绝、合同/法律条款/合规声明等严谨连续文本、原样转录任务。
-
-> [!CAUTION]
-> 命中后，**MUST** 先读取 [`references/lark-doc-whiteboard.md`](references/lark-doc-whiteboard.md) 并**严格按其流程执行**。
->
-> **绝对禁止**用 `whiteboard-cli` 渲染 PNG 后通过 `docs +media-insert` 插入文档——图表必须通过 `lark-cli whiteboard +update` 写入画板 block，这是唯一合法路径。
+> **格式选择规则（全局）：**
+> - **创建 / 导入场景**（`docs +create`，或 `docs +update --command append/overwrite` 的整段写入）：XML 和 Markdown 都可以。用户提供 `.md` 本地文件、或明确说"导入 Markdown"时，直接用 Markdown；否则默认 XML（可用 callout、grid、checkbox 等富 block）。
+> - **精准编辑场景**（`docs +update` 的 `str_replace` / `block_insert_after` / `block_replace` / `block_delete` / `block_move_after` 等局部精修指令）：优先使用 XML（`--doc-format xml`，即默认值）。XML 能稳定表达 block 结构和样式，局部精修更可控；不要因为 Markdown 更简单就自行切换。
 
 ## 快速决策
-- 用户说“看一下文档里的图片/附件/素材”“预览素材”，优先用 `lark-cli docs +media-preview`。
-- 用户明确说“下载素材”，再用 `lark-cli docs +media-download`。
-- 如果目标明确是画板 / whiteboard / 画板缩略图，只能用 `lark-cli docs +media-download --type whiteboard`，不要用 `+media-preview`。
-- 用户说“找一个表格”“按名称搜电子表格”“找报表”“最近打开的表格”，先用 `lark-cli docs +search` 做资源发现。
-- `docs +search` 不是只搜文档 / Wiki；结果里会直接返回 `SHEET` 等云空间对象。
-- 拿到 spreadsheet URL / token 后，再切到 `lark-sheets` 做对象内部读取、筛选、写入等操作。
-- 用户说“给文档加评论”“查看评论”“回复评论”“给评论加表情 / reaction”“删除评论表情 / reaction”，**不要留在 `lark-doc`**，直接切到 `lark-drive` 处理。
+- 用户需要在文档内**创建、复制或移动**资源块（画板、电子表格、多维表格等）时，必须先读取 [`lark-doc-xml.md`](references/lark-doc-xml.md) 的「三、资源块」章节
+- 用户说"看一下文档里的图片/附件/素材""预览素材" → 用 `lark-cli docs +media-preview`
+- 用户明确说"下载素材" → 用 `lark-cli docs +media-download`
+- 如果目标是画板/whiteboard/画板缩略图 → 只能用 `lark-cli docs +media-download --type whiteboard`（不要用 `+media-preview`）
+- 用户说"找一个表格""按名称搜电子表格""找报表""最近打开的表格""最近我编辑过的 xxx" → 直接用 `lark-cli drive +search`（参考 [`lark-drive`](../lark-drive/references/lark-drive-search.md)）。**老的 `docs +search` 已进入维护期、后续会下线，不要再新增依赖。**
+- `drive +search` 结果里会直接返回 `SHEET` / `Base` / `FOLDER` 等云空间对象，是资源发现的统一入口
+- 拿到 spreadsheet URL/token 后 → 切到 `lark-sheets` 做对象内部操作
+- 用户说"给文档加评论""查看评论""回复评论""给评论加/删除表情 reaction" → 切到 `lark-drive` 处理
+- 文档内容中出现嵌入的 `<sheet>`、`<bitable>` 或 `<cite file-type="sheets|bitable">` 标签时 → **必须主动提取 token 并切到对应技能下钻读取内部数据**，不能只呈现标签本身
 
-## 补充说明 
-`docs +search` 除了搜索文档 / Wiki，也承担“先定位云空间对象，再切回对应业务 skill 操作”的资源发现入口角色；当用户口头说“表格 / 报表”时，也优先从这里开始。
+| 标签 / 属性 | 提取字段 | 切到技能 |
+|-|-|-|
+| `<sheet token="..." sheet-id="...">` | `token` -> spreadsheet_token, `sheet-id` | [`lark-sheets`](../lark-sheets/SKILL.md) |
+| `<bitable token="..." table-id="...">` | `token` -> app_token, `table-id` | [`lark-base`](../lark-base/SKILL.md) |
+| `<cite type="doc" file-type="sheets" token="..." sheet-id="...">` | 同 `<sheet>` | [`lark-sheets`](../lark-sheets/SKILL.md) |
+| `<cite type="doc" file-type="bitable" token="..." table-id="...">` | 同 `<bitable>` | [`lark-base`](../lark-base/SKILL.md) |
+| `<synced_reference src-token="..." src-block-id="...">` | `src-token` -> doc_token, `src-block-id` -> block_id | 用 `docs +fetch` 读取 src-token 文档，定位 block |
+
+**补充：** 云空间资源发现统一走 [`drive +search`](../lark-drive/references/lark-drive-search.md)；当用户口头说"表格/报表/最近我编辑过的 xxx"时，也优先从 `drive +search` 开始。老的 `docs +search` 只在沿用 `--filter` JSON 的存量脚本里保留，后续会下线。

-- **`doc_id`**（string）：文档的唯一标识符（token），格式如 `doxcnXXXXXXXXXXXXXXXXXXX`
-- **`doc_url`**（string）：文档的访问链接，可直接在浏览器中打开
-- **`message`**（string）：操作结果消息，如"文档创建成功"
-- **`permission_grant`**（object，可选）：仅 `--as bot` 时返回，说明是否已自动为当前 CLI 用户授予可管理权限
+- **`document.new_blocks`**：本次操作新增的 block 列表（如画板）。`block_id` 可用于 `docs +update` 的 `--block-id` 做精确编辑；`block_token` 是资源块（如画板）的 token，可交给 `lark-whiteboard` 等 skill 继续操作
 
-> [!IMPORTANT]
-> 当文档创建在 `wiki_node` 或 `wiki_space` 下时，返回的 `doc_url` 可能是 `/wiki/...` 形式的知识库链接，而不是 `/docx/...` 形式的文档链接。

 > - `status = skipped`：本地没有可用的当前用户 `open_id`，因此不会自动授权；可提示用户先完成 `lark-cli auth login`，再让 AI / agent 继续使用应用身份（bot）授予当前用户权限
 > - `status = failed`：文档已创建成功，但自动授权用户失败；会带上失败原因，并提示稍后重试或继续使用 bot 身份处理该文档
 >

-## 重要：创建文档后的可视化流程
-
-如果文档中包含空白画板（`<whiteboard type="blank"></whiteboard>`），**必须继续以下步骤**：
-
-1. 从返回值的 `data.board_tokens` 字段记录所有新建画板的 token
-2. 读取 `../../lark-whiteboard/SKILL.md`，跳至"渲染 & 写入画板"章节，为每个 board_token 生成并写入实际内容
-3. 确认所有画板都有实际内容后，任务才算完成

-**仅创建空白画板是不够的！** 如果只创建空白画板而不填充内容，任务将被视为未完成。
-
-> ⚠️ **警告**：务必检查返回值中是否有 `board_tokens` 字段。如果有，说明创建了空白画板，必须继续填充内容！
-
 ## 参数
 
-| 参数 | 必填 | 说明 |
-|------|------|------|
-| `--markdown` | 是 | 文档的 Markdown 内容（Lark-flavored Markdown 格式） |
-| `--title` | 否 | 文档标题 |
-| `--folder-token` | 否 | 父文件夹 token（与 `--wiki-node`、`--wiki-space` 互斥） |
-| `--wiki-node` | 否 | 知识库节点 token 或 URL（与 `--folder-token`、`--wiki-space` 互斥） |
-| `--wiki-space` | 否 | 知识空间 ID，特殊值 `my_library` 表示个人知识库（与 `--folder-token`、`--wiki-node` 互斥） |
-
-### markdown（必填）
-文档的 Markdown 内容，使用 Lark-flavored Markdown 格式。
-
-调用本工具的 markdown 内容应当尽量结构清晰，样式丰富，有很高的可读性。合理地使用 callout 高亮块、分栏、表格、图片和空白画板等能力，做到图文并茂。
-
-你需要遵循以下原则：
-- **结构清晰**：标题层级 ≤ 4 层，用 Callout 突出关键信息
-- **视觉节奏**：用分割线、分栏、表格打破大段纯文字
-- **图文交融**：流程、架构或草图需要可视化时，优先使用图片、表格或空白画板
-- **克制留白**：Callout 不过度、加粗只强调核心词
-- **主动画板**：文档涉及架构、流程、组织、时间线、因果等逻辑关系时，**必须**在 markdown 对应章节的文字内容之后插入 `<whiteboard type="blank"></whiteboard>` 占位，每个图表对应一个标签。**禁止**用 `whiteboard-cli` 渲染的 PNG/SVG 图片替代画板。创建完成后从返回值 `data.board_tokens` 取 token，读取 `../../lark-whiteboard/SKILL.md` 的"渲染 & 写入画板"章节为每个 token 写入图表内容。例：文档含"系统整体架构""分层架构""部署架构"各需插入一个画板，"类图"也需插入一个画板（走 Mermaid 路由）。
-
-当用户有明确的样式、风格需求时，应当以用户的需求为准！
-
-**重要提示**：
-- **禁止重复标题**：markdown 内容开头不要写与 title 相同的一级标题！title 参数已经是文档标题，markdown 应直接从正文内容开始
-- **目录**：飞书自动生成，无需手动添加
-- Markdown 语法必须符合 Lark-flavored Markdown 规范，详见下方"内容格式"章节
-- 创建较长的文档时，强烈建议配合 `docs +update --mode append`，进行分段的创建，提高成功率
-
-### folder-token（可选）
-父文件夹的 token。如果不提供，文档将创建在用户的个人空间根目录。
-
-folder_token 可以从飞书文件夹 URL 中获取，格式如：`https://xxx.feishu.cn/drive/folder/fldcnXXXX`，其中 `fldcnXXXX` 即为 folder_token。
-
-### wiki-node（可选）
-知识库节点 token 或 URL（可选，传入则在该节点下创建文档，与 folder-token 和 wiki-space 互斥）
-
-wiki_node 可以从飞书知识库页面 URL 中获取，格式如：`https://xxx.feishu.cn/wiki/wikcnXXXX`，其中 `wikcnXXXX` 即为 wiki_node token。
-
-### wiki-space（可选）
-知识空间 ID（可选，传入则在该空间根目录下创建文档。特殊值 `my_library` 表示用户的个人知识库。与 wiki-node 和 folder-token 互斥）
-
-wiki_space 可以从知识空间设置页面 URL 中获取，格式如：`https://xxx.feishu.cn/wiki/settings/7000000000000000000`，其中 `7000000000000000000` 即为 wiki_space ID。
-
-**参数优先级**：wiki-node > wiki-space > folder-token
-
-## 示例
-
-### 示例 1：创建简单文档
-
-```bash
-lark-cli docs +create --title "项目计划" --markdown "## 项目概述
-
-这是一个新项目。
-
-## 目标
-
-- 目标 1
-- 目标 2"
-```
-
-### 示例 2：使用飞书扩展语法
-
-```bash
-lark-cli docs +create --title "产品需求" --markdown '<callout emoji="💡" background-color="light-blue">
-重要需求说明
-</callout>'
-```
-
-# 内容格式
-
-文档内容使用 **Lark-flavored Markdown** 格式，这是标准 Markdown 的扩展版本，支持飞书文档的所有块类型和富文本格式。
-
-## 通用规则
-
-- 使用标准 Markdown 语法作为基础
-- 使用自定义 XML 标签实现飞书特有功能（具体标签见各功能章节）
-- 只有当字符会被解释为 Markdown / Lark 富文本语法时，才需要使用反斜杠转义：``* ~ ` $ [ ] < > { } | ^``
-- 普通文本中的孤立字符不要过度转义。例如 `5 * 3`、`version~1.0`、`final_trajectory` 通常应保持原样，只有像 `*斜体*`、`**粗体**`、`~~删除线~~` 这种会触发格式化的写法，想按字面量显示时才需要转义
-
----
-
-## 基础块类型
-
-### 文本（段落）
-
-```markdown
-普通文本段落
-
-段落中的**粗体文字**
-
-多个段落之间用空行分隔。
-
-居中文本 {align="center"}
-右对齐文本 {align="right"}
-```
-
-**段落对齐**：支持 `{align="left|center|right"}` 语法。可与颜色组合：`{color="blue" align="center"}`
-
-### 标题
-
-飞书支持 9 级标题。H1-H6 使用标准 Markdown 语法，H7-H9 使用 HTML 标签：
-
-```markdown
-# 一级标题
-## 二级标题
-### 三级标题
-#### 四级标题
-##### 五级标题
-###### 六级标题
-<h7>七级标题</h7>
-<h8>八级标题</h8>
-<h9>九级标题</h9>
-
-# 带颜色的标题 {color="blue"}
-## 红色标题 {color="red"}
-# 居中标题 {align="center"}
-## 蓝色居中标题 {color="blue" align="center"}
-```
-
-**标题属性**：支持 `{color="颜色名"}` 和 `{align="left|center|right"}` 语法，可组合使用。颜色值：red, orange, yellow, green, blue, purple, gray。请谨慎使用该能力。
-
-### 列表
-
-有序列表、无序列表嵌套使用 tab 或者 2 空格缩进：
-
-```markdown
-- 无序项1
-  - 无序项1.a
-  - 无序项1.b
-
-1. 有序项1
-2. 有序项2
-
-- [ ] 待办
-- [x] 已完成
-```
-
-### 引用块
-
-```markdown
-> 这是一段引用
-> 可以跨多行
-
-> 引用中支持**加粗**和*斜体*等格式
-```
-
-### 代码块
-
-**注意**：只支持围栏代码块（` ``` `），不支持缩进代码块。
-
-````markdown
-```python
-print("Hello")
-```
-````
-
-支持语言：python, javascript, go, java, sql, json, yaml, shell 等。
-
-### 分割线

-<column>
-
-左栏内容
-
-</column>
-<column>
-
-右栏内容
-
-</column>
-</grid>
-```

-</grid>
-```
-
-**属性**: `cols`(列数 2-5), `width`(列宽百分比，总和为 100，等宽时可省略)
-
-### 表格
-
-#### 标准 Markdown 表格
-
-```markdown
-| 列 1 | 列 2 | 列 3 |
-|------|------|------|
-| 单元格 1 | 单元格 2 | 单元格 3 |
-| 单元格 4 | 单元格 5 | 单元格 6 |
-```
-
-#### 飞书增强表格
-
-当单元格需要复杂内容（列表、代码块、高亮块等）时使用。
-
-**层级结构**（必须严格遵守）：
-```
-<lark-table>                    <- 表格容器
-  <lark-tr>                     <- 行（直接子元素只能是 lark-tr）
-    <lark-td>内容</lark-td>     <- 单元格（直接子元素只能是 lark-td）
-    <lark-td>内容</lark-td>     <- 每行的 lark-td 数量必须相同！
-  </lark-tr>
-</lark-table>
-```
-
-**属性**：
-- `column-widths`：列宽，逗号分隔像素值，总宽约 730
-- `header-row`：首行是否为表头（`"true"` 或 `"false"`）
-- `header-column`：首列是否为表头（`"true"` 或 `"false"`）
-
-**单元格写法**：内容前后必须空行
-```html
-<lark-td>
-
-这里写内容
-
-</lark-td>
-```
-
-**完整示例**（2行3列）：
-```html
-<lark-table column-widths="200,250,280" header-row="true">
-<lark-tr>
-<lark-td>
-
-**表头1**
-
-</lark-td>
-<lark-td>
-
-**表头2**
-
-</lark-td>
-<lark-td>
-
-**表头3**
-
-</lark-td>
-</lark-tr>
-<lark-tr>
-<lark-td>
-
-普通文本
-
-</lark-td>
-<lark-td>
-
-- 列表项1
-- 列表项2
-
-</lark-td>
-<lark-td>
-
-代码内容
-
-</lark-td>
-</lark-tr>
-</lark-table>
-```
-
-**限制**：单元格内不支持 Grid 和嵌套表格
-
-**合并单元格**：读取时返回 `rowspan/colspan` 属性，创建暂不支持
-
-**禁止**：
-- 混用 Markdown 表格语法（`|---|`）
-- 使用 `<br/>` 换行
-- 遗漏 `<lark-td>` 标签
-
-### 图片
-
-```html
-<image url="https://example.com/image.png" width="800" height="600" align="center" caption="图片描述文字"/>
-```
-
-**属性**: url (必需，系统会自动下载并上传), width, height, align (left/center/right), caption
-
-**注意**: 不支持直接使用 `token` 属性（如 `<image token="xxx"/>`），只支持 URL 方式。系统会自动下载图片并上传到飞书。
-
-支持 PNG/JPG/GIF/WebP/BMP，最大 10MB
-
-**图片/文件插入方式选择**：
-- **有公开可访问的图片 URL** → 直接在 `docs +create` / `docs +update` 的 markdown 中使用 `<image url="..."/>` 一步到位
-- **本地图片或文件** → 先用 `docs +create` / `docs +update` 创建或更新文档文本内容，再用 `lark-doc-media-insert`（docs +media-insert）将本地图片或文件追加到文档末尾
-
-### 文件
-
-```html
-<file url="https://example.com/document.pdf" name="文档.pdf" view-type="1"/>
-```
-
-**属性**:

-- view-type (1=卡片视图, 2=预览视图，可选)
-
-**注意**: 不支持直接使用 `token` 属性（如 `<file token="xxx"/>`）
-
-### 画板
-
-创建空白画板时，直接在 markdown 中写 `<whiteboard type="blank"></whiteboard>`。
-
-自然语言请求示例：
-- “帮我创建一个带单个空白画板的文档”
-- “帮我创建一个文档，里面放两个空白画板”
-
-```bash
-# 创建带单个空白画板的文档
-lark-cli docs +create --title "空白画板示例" --markdown '<whiteboard type="blank"></whiteboard>'
-```
-
-```html
-<whiteboard type="blank"></whiteboard>
-```
-
-一次创建多个空白画板时，在同一个 markdown 里重复多个标签：
-
-```html
-<whiteboard type="blank"></whiteboard>
-<whiteboard type="blank"></whiteboard>
-```
-
-#### 读取画板
-
-读取时返回 `<whiteboard>` 标签：
-
-```html
-<whiteboard token="xxx" align="center" width="800" height="600"/>
-```
-
-**重要说明**：
-- 创建空白画板时，直接使用 `<whiteboard type="blank"></whiteboard>`
-- 读取时只能获取 token，可通过 media-download 查看内容，无法直接读出画板内部内容
-- 画板编辑：详见 [../../lark-whiteboard/SKILL.md](../../lark-whiteboard/SKILL.md)

 ## 最佳实践
 
-- **空行分隔**：不同块类型之间用空行分隔
-- **转义字符**：只有在字符会触发格式化时才用 `\` 转义。例如想输出字面量 `*斜体*` 时写成 `\*斜体\*`；但 `5 * 3`、`version~1.0`、`final_trajectory` 这类普通文本通常不需要转义
-- **图片**：使用 URL，系统自动下载上传
-- **分栏**：列宽总和必须为 100
-- **表格选择**：简单数据用 Markdown，复杂嵌套用 `<lark-table>`
-- **提及**：@用户用 `<mention-user>`，@文档用 `<mention-doc>`
-- **目录**：飞书自动生成，无需手动添加
+- 文档标题从内容中自动提取（XML `<title>` 或 Markdown `#`），不要在内容开头重复写标题
+- 创建较长的文档时，先创建基础内容，再用 `docs +update --command block_insert_after` 分段追加
+- **视觉丰富度**：必须遵循 [`lark-doc-style.md`](style/lark-doc-style.md) 中的样式指南，主动使用结构化 block 丰富文档

+| **编辑**：任何修改文档内容的需求 | `full` | 包含 block ID + 样式属性 + 引用元数据，提供完整文档结构信息 |
+
+
+## 选 `--scope`（读取范围）
+
+`--scope` 和 `--detail` 正交可组合。**省略 `--scope` 即读整篇；获取一小节时优先用局部读取。**
+
+| 模式 | 何时用 | 关键参数 | 行为要点 |
+|-|-|-|-|
+| `outline` | 不知道结构，先看目录 | `--max-depth`（标题层级上限） | 扁平列出所有标题，**包括嵌在容器里的内嵌标题**（如 callout 里的 h3）；这些 id 可直接作后续 `section` / `range` 端点 |
+| `section` | 读某个标题对应的整节 | `--start-block-id`（必填） | 顶层标题 → 展开到下一同级/更高级标题前；容器内节点（含内嵌标题） → 按"最小包容单元"返回容器/表格切片，不做 heading 扩展；顶层非标题块 → 仅该块 |
+| `range` | 已知精确起止 | `--start-block-id` / `--end-block-id` 至少一个；`-1` = 读到末尾 | 两端同顶层 → 顶层序列切片；两端同一容器 → 容器整体；两端同一表格 → 瘦身切片；**跨顶层 → 端点所在顶层块整块输出，不做瘦身** |
+| `keyword` | 只有模糊关键词 | `--keyword`（不区分大小写、子串，`\|` 分隔多词 OR） | 每处命中按"最小包容单元"输出；**自动去重**（同容器多命中 → 单个容器，同表格多行命中 → 合并切片） |
+
+**设置 `--scope` 时共用** `--context-before` / `--context-after` / `--max-depth`。
+
+- `--max-depth`：`outline` = 标题层级上限（3 = h1~h3）；其它模式 = 被选块的子树遍历深度（`-1` 不限，`0` 仅块自身）。
+- `--context-before/--context-after`：**只对整块顶层单元生效**；命中落在容器/表格内（返回容器或切片）时 before/after 被忽略，需要更大范围改用 `section` / `range` 显式指定。
+
+**决策顺序**（核心原则：**局部获取优于全量获取**，能精确到节/区间就绝不全量拉取；**任何文档的第一次读取都应从 `outline` 开始**）：
+1. **第一次接触文档 / 不知道结构** → 先 `outline` 探测目录（**强制首步，无论文档是"目标"还是"引用源"**），再回到 2/3 精读
+2. 改/读某个**标题对应的整节** → `section`（最省心，**首选精读方式**）
+3. 精确自定义起止 / 跨节连续区间 → `range`
+4. 只有模糊关键词 → `keyword`
+5. **兜底**：确实需要整篇文档时才不传 `--scope`（默认整篇）；**不要为了省事就读整篇**，局部模式上下文更省、响应更快
+
+**推荐双步流程**：`outline --max-depth 3` 拿目录 → `section --start-block-id <标题id> --detail with-ids` 精读该节。
+
+## 局部读取的输出结构：`<fragment>` 与 `<excerpt>`
+
+设置 `--scope` 时返回的 `content` 被一个 `<fragment>` 节点包裹，属性包含 `mode` / `requested-start` / `requested-end` / `keyword`（按需）。子节点只有两种形态：
+
+- **顶层块**：完整块直接作为 `<fragment>` 的子节点，无额外包裹。
+- **`<excerpt top-block-id="..." parent-block-path="...">`**：非顶层节选（容器整体 / 表格瘦身切片）。
+  - `top-block-id`：所在顶层块 id，想看该块全貌时作 `section` / `range` 锚点再拉一次。
+  - `parent-block-path`：从顶层块到 excerpt 内容直接父节点的 id 路径，`/` 分隔（表格切片时即表格自身 id）。
+
+**看到 `<excerpt>` 即意味着这是节选**，不能假设看到了该顶层块的全貌。
+
+**表格默认瘦身**：即便 `<table>` 本身是顶层块也只返回 thead + 命中 tr。想拿整张表 → `range --start-block-id <table-id> --end-block-id <table-id>`；切片范围恰好覆盖全部 tr 时 SDK 自动升级为整块、不包 `<excerpt>`。
+
+## 返回值
+
+```json
+{
+  "ok": true,
+  "identity": "user",
+  "data": {
+    "document": {
+      "document_id": "doxcnXXXX",
+      "revision_id": 12,
+      "content": "<title>标题</title><p>文档内容...</p>"
+    }
+  }
+}
+```
+
+`content` 的格式由 `--doc-format` 决定。设置 `--scope` 时会被 `<fragment>` 包裹，详见上文"局部读取的输出结构"。

-## 重要：图片、文件、画板的处理
+## 图片、文件、画板的处理
 
-**文档中的图片、文件、画板需要通过独立的 media shortcut 单独获取。**
+**文档中的素材以 XML 标签形式出现：**
 
-### 识别格式
-
-返回的 Markdown 中，媒体文件以 HTML 标签形式出现：
-
-- **图片**：
-  ```html
-  <image token="Z1FjxxxxxxxxxxxxxxxxxxxtnAc" width="1833" height="2491" align="center"/>
-  ```
-
-- **文件**：
-  ```html
-  <view type="1">
-    <file token="Z1FjxxxxxxxxxxxxxxxxxxxtnAc" name="skills.zip"/>
-  </view>
-  ```
-
-- **画板**：
-  ```html
-  <whiteboard token="Z1FjxxxxxxxxxxxxxxxxxxxtnAc"/>
-  ```
-- 画板编辑：详见 [SKILL.md](../SKILL.md#重要说明画板编辑)
-
-### 获取步骤
-
-1. 从 HTML 标签中提取 `token` 属性值
-2. 如果目标是图片/文件素材，且用户只是想查看/预览，调用 [`lark-doc-media-preview`](lark-doc-media-preview.md)（`docs +media-preview`）：
-   ```bash
-   lark-cli docs +media-preview --token "提取的token" --output ./preview_media
-   ```
-3. 如果用户明确要下载，或目标是 `<whiteboard token="..."/>`，调用 [`lark-doc-media-download`](lark-doc-media-download.md)（`docs +media-download`）：
-   ```bash
-   lark-cli docs +media-download --token "提取的token" --output ./downloaded_media
-   ```
-
-## Wiki URL 处理策略
-
-知识库链接（`/wiki/TOKEN`）背后可能是云文档、电子表格、多维表格等不同类型的文档。当不确定类型时，**不能直接假设是云文档**，必须先查询实际类型。
-
-### 处理流程
-
-1. **先调用 lark-wiki 解析 wiki token**
-2. **从返回的 `node` 中获取 `obj_type`（实际文档类型）和 `obj_token`（实际文档 token）**
-3. **根据 `obj_type` 调用对应工具**：
-
-| obj_type | 工具 | 说明 |
-|----------|------|------|
-| `docx` | `lark-doc-fetch` | 云文档 |
-| `sheet` | `lark-sheet` | 电子表格 |
-| `bitable` | `lark-base` | 多维表格 |
-| 其他 | 告知用户暂不支持 | — |
-
-## 重要：任务卡片（task 标签）
-
-`docs +fetch` 默认不会查询/展开文档中内嵌的任务详情（例如任务标题、状态、负责人等）。
-它会在返回的 Markdown 中保留任务引用，并返回任务 ID（GUID），例如：
-
-```html
-<task task-id="30597dc9-262e-4597-97f4-f8efcd1aeb95"></task>
+```xml
+<img token="..." url="https://..." width="..." height="..."/>
+<source token="..." url="https://..." name="skills.zip"/>
+<whiteboard token="..."/>
 ```
 
-如果用户需要查看该任务的详情，需要用返回的 `task-id` 再调用任务 CLI 查询：
+- `<img>` / `<source>` 带 `url` 时，直接用该 URL 下载即可（普通 HTTP GET），无需走 shortcut。
+- 没有 `url`、或只想预览 → `docs +media-preview --token <token> --output ./preview_media`
+- 明确下载，或目标是 `<whiteboard>`（画板只能走 shortcut） → `docs +media-download --token <token> --output ./downloaded_media`
 
-```bash
-lark-cli task tasks get --as user --params '{"task_guid":"30597dc9-262e-4597-97f4-f8efcd1aeb95"}'
-```
+## 嵌入电子表格 / 多维表格
 
-## 工具组合
-
-| 需求 | 工具 |
-|------|------|
-| 获取文档文本 | `docs +fetch` |
-| 预览图片/文件素材 | `docs +media-preview` |
-| 下载图片/文件/画板 | `docs +media-download` |
-| 创建新文档 | `docs +create` |
-| 更新文档内容 | `docs +update` |
+返回中可能含 `<sheet>`、`<bitable>`、`<cite file-type="sheets|bitable">`。内部数据无法通过 `docs +fetch` 获取，提取 `token` 等属性后切到 [`lark-sheets`](../../lark-sheets/SKILL.md) / [`lark-base`](../../lark-base/SKILL.md) 下钻，详见 [SKILL.md 快速决策](../SKILL.md) 路由表。

+# Markdown 格式参考
+
+`docs +fetch / +create / +update` 使用 `--doc-format markdown` 时适用。
+
+## 转义规则
+
+> **⚠️ 当文本中包含以下字符且不想触发 Markdown 语法时**，需用 `\` 前缀转义。转义分为**无条件转义**（行内任意位置生效）和**位置敏感转义**（仅特定位置才需要）两类。
+
+### 无条件转义（行内生效，任何位置都要转义）
+
+| 符号 | Markdown 语法用途 | 转义写法 | 示例 |
+|------|-------------------|----------|------|
+| `\` | 转义符本身 | `\\` | `C:\\Users` → C:\Users |
+| `` ` `` | 行内代码 | `` \` `` | `` 用 \` 包裹 `` |
+| `*` | 斜体 / 加粗 | `\*` | `3 \* 5 = 15` → 3 \* 5 = 15 |
+| `_` | 斜体 / 加粗 | `\_` | `foo\_bar\_baz` → foo\_bar\_baz |
+| `[` `]` | 链接文本 | `\[` `\]` | `\[非链接\]` |
+| `$` | 数学公式定界 | `\$` | `价格 \$100` |
+| `~` | 删除线（GFM `~~text~~`） | `\~` | `a\~\~b\~\~c` → a~~b~~c |
+| `<` | XML 标签起始（`<b>`、`<img>` 等会被当作标签解析并生效） | `\<` | 字面量 `<b>` 须写为 `\<b>`；`a < b` 建议写为 `a \< b` |
+
+### 位置敏感转义（仅在特定位置才需要转义）
+
+| 符号 | Markdown 语法用途 | 转义条件 | 示例 |
+|------|-------------------|----------|------|
+| `#` | 标题 | **仅行首**（去除前导空白后）| 行首 `\# 这不是标题`；行内 `A # B` 无需转义 |
+| `+` | 无序列表 | **仅行首**（去除前导空白后）| 行首 `\+ item`；行内 `1 + 2` 无需转义 |
+| `-` | 无序列表 / 分隔线 | **仅行首**（去除前导空白后）| 行首 `\- item`；行内 `A - B` 无需转义 |
+| `>` | 引用块 | **仅行首**（去除前导空白后）| 行首 `\> 不是引用`；行内 `a > b` 无需转义 |
+| `\|` | 表格 cell 分隔 | **仅在 GFM 表格 cell 内** | cell 内 `A \| B`；行内普通文本 `a \| b` 无需转义 |
+
+**不需要转义的场景：**
+- 在 `` ` `` 行内代码或 ` ``` ` 代码块内，所有符号均为字面量，无需转义
+- `$...$` 数学公式内部，符号为 LaTeX 语法，不受 Markdown 转义影响
+
+**导出已转义，不要反转义：**
+`docs +fetch --doc-format markdown` 导出的内容中，特殊字符**已经被转义过了**（例如 `\[`、`\|`、`\\` 等）。这些 `\` 是有意义的——去掉会导致后续写入时字符被 Markdown 语法吞掉。**不要反转义或去掉 `\`。**
+
+**写入时必须转义：**
+使用 `docs +create` 或 `docs +update` 的 `--doc-format markdown` 写入内容时，字面文本中的特殊字符同样必须转义。`--pattern` 参数中也必须使用转义形式才能正确匹配。
+
+**导出 → 更新 工作流示例：**
+
+1. `docs +fetch` 导出得到 `C:\\Users\\test\[1\]`
+2. 用 `str_replace --pattern 'C:\\Users\\test\[1\]'` 匹配（直接使用导出的转义形式）
+3. `--content` 中的替换内容也要保持转义：`C:\\Users\\prod\[2\]`
+
+自行构造 Markdown 内容写入时同理：如字面文本 `a]b` 应写为 `a\]b`，`C:\Users` 应写为 `C:\\Users`。
+
+## Shell 传参
+- **首选文件传参**：`--content` 支持 `@path/to/file.md`（读文件）和 `-`（读 stdin），彻底绕开 shell 转义；多行、含特殊字符、长文本强烈推荐。字面量以 `@` 开头时用 `@@` 转义（`--pattern` 不支持 `@file`）
+- **默认用单引号 `'...'`**：完全字面量，`$`、`` ` ``、`\`、`>`、`\<b>` 等全部原样保留
+- **双引号 `"..."`**：会展开 `$变量`、反引号和 `$(...)` 命令替换，`\` 仍参与转义，易踩坑
+- **`$'...'` ANSI-C 引号**：按 C 转义解析，`\n`=换行、`\\`=单个 `\`；**zsh 下未知转义（如 `\<`）的 `\` 会被吞**，要保留字面 `\` 必须写 `\\`。只在确实需要 `\n`/`\t` 时用
+- **多行内容**：用 `<<'EOF'` heredoc，EOF 必须带引号，否则仍展开 `$`
+- **`\n` 在 `'...'` 和 `"..."` 里都是字面量**，不是换行；要真换行用 `$'...\n...'` 或 heredoc
+
+## 图片语法
+
+Markdown 格式支持通过 URL 插入网络图片，图片将自动从 HTTP 下载：
+```markdown
+![alt text](https://example.com/photo.png)
+```
+- `alt text` 为图片描述（可选，可留空）
+- URL 支持 `http://` 和 `https://` 协议
+- 对应的 XML 格式为：`<img href="https://example.com/photo.png"/>`
+
+## Markdown 不支持的 Block 类型
+
+非原生 Markdown 语法的内容（如下划线、高亮框(Callout)、勾选框、多维表格、画板、思维导图、电子表格、网格布局、引用(@文档/@人)、按钮、日期提醒、行内文件、文字颜色/背景色、同步块等）采用 XML 语法表示，详见 [`lark-doc-xml.md`](lark-doc-xml.md)。
+> **⚠️ XML 标签会被解析并生效**：即使在 `--doc-format markdown` 下，`<b>`、`<u>`、`<img>` 等 XML 标签也会被识别为对应的富文本节点，**不会**按字面量显示。如需字面量输出尖括号包裹的文本（例如示例中的 `<tag>`），必须转义左尖括号：`\<b>`、`\<img>`。

-   - 适合替换短文本、关键词等
+```bash
+# 简单文本替换
+lark-cli docs +update --api-version v2 --doc "<doc_id>" --command str_replace \
+  --pattern "张三" --content "李四"
 
-**转义说明**：如果要匹配的内容本身包含 `...`，使用 `\.\.\.` 表示字面量的三个点。
+# 替换为富文本（加粗 + 链接）
+lark-cli docs +update --api-version v2 --doc "<doc_id>" --command str_replace \
+  --pattern "旧链接" --content '<b>新链接</b> <a href="https://example.com">点击查看</a>'
 
-示例：
-- `你好...世界` → 匹配从"你好"到"世界"之间的任意内容
-- `你好\.\.\.世界` → 匹配字面量 "你好...世界"
+# 仅当用户明确要求时才使用 Markdown
+lark-cli docs +update --api-version v2 --doc "<doc_id>" --command str_replace \
+  --doc-format markdown --pattern "旧内容" --content "新内容"
 
-**建议**：如果文档中有多个 `...`，建议使用更长的上下文来精确定位，避免歧义。
+# Markdown 模式下支持跨行匹配（--pattern 与 --content 都需要真实换行；"..."/'...' 里的 \n 是字面量）
+# 多行内容推荐 heredoc 或 --content @file.md，避免 shell 转义踩坑
+lark-cli docs +update --api-version v2 --doc "<doc_id>" --command str_replace \
+  --doc-format markdown \
+  --pattern "$(printf '## 旧标题\n\n第一段原文\n\n第二段原文')" \
+  --content - <<'EOF'
+## 新标题
 
-## selection-by-title - 标题定位
+改写后的第一段
 
-格式：`## 章节标题`（可带或不带 # 前缀）
+改写后的第二段
+EOF
 
-自动定位整个章节（从该标题到下一个同级或更高级标题之前）。
+# Markdown 模式下使用 `前缀...后缀` 省略号匹配首尾特征明显的大段内容
+# 下例会把「## 旧标题」到「结束语。」之间的所有内容整体替换
+lark-cli docs +update --api-version v2 --doc "<doc_id>" --command str_replace \
+  --doc-format markdown \
+  --pattern "## 旧标题...结束语。" \
+  --content - <<'EOF'
+## 新标题
 
-**示例**：
-- `## 功能说明` → 定位二级标题"功能说明"及其下所有内容
-- `功能说明` → 定位任意级别的"功能说明"标题及其内容
+重写后的正文...
 
-# 可选参数
+新的结束语。
+EOF
 
-## new-title
+# 删除文本：--content 传空字符串即可
+lark-cli docs +update --api-version v2 --doc "<doc_id>" --command str_replace \
+  --pattern "废弃的内容" --content ""
+```
 
-更新文档标题。如果提供此参数，将在更新文档内容后同步更新文档标题。
+### block_insert_after — 在指定 block 之后插入
 
-**特性**：
-- 仅支持纯文本，不支持富文本格式
-- 长度限制：1-800 字符
-- 可以与任何 mode 配合使用
-- 标题更新在内容更新之后执行
+```bash
+lark-cli docs +update --api-version v2 --doc "<doc_id>" --command block_insert_after \
+  --block-id "目标 block_id" \
+  --content '<h2>新章节</h2><ul><li>要点 1</li><li>要点 2</li></ul>'
+```
 
-# 返回值
+### block_replace — 替换指定 block
 
-## 成功
+```bash
+lark-cli docs +update --api-version v2 --doc "<doc_id>" --command block_replace \
+  --block-id "目标 block_id" \
+  --content '<p>替换后的段落内容</p>'
+```
+
+### block_delete — 删除指定 block
+
+```bash
+lark-cli docs +update --api-version v2 --doc "<doc_id>" --command block_delete \
+  --block-id "目标 block_id"
+```
+
+### overwrite — 全文覆盖
+
+```bash
+lark-cli docs +update --api-version v2 --doc "<doc_id>" --command overwrite \
+  --content '<title>全新文档</title><h1>概述</h1><p>新的内容</p>'
+```
+
+> ⚠️ 会清空文档后重写，可能丢失图片、评论等。仅在需要完全重建文档时使用。
+
+### append — 在文档末尾追加
+
+```bash
+lark-cli docs +update --api-version v2 --doc "<doc_id>" --command append \
+  --content '<h2>新增章节</h2><p>追加的内容</p>'
+```
+
+> 等价于 `block_insert_after --block-id -1`，无需先获取 block ID。
+
+### block_copy_insert_after — 复制块并插入
+
+将一个或多个源块复制到锚点块之后，源块保持不变。`--src-block-ids` 为逗号分隔的源块 ID，按顺序依次插入到锚点之后。
+
+```bash
+# 复制多个块（按顺序插入：anchor → a → b → c）
+lark-cli docs +update --api-version v2 --doc "<doc_id>" --command block_copy_insert_after \
+  --block-id "锚点 block_id" \
+  --src-block-ids "block_a,block_b,block_c"
+```
+
+### block_move_after — 移动已有 block
+
+将文档中已有的 block 移动到指定锚点之后。使用 `--src-block-ids` 指定要移动的块 ID，无需 `--content`。
+
+```bash
+# 移动到页面末尾
+lark-cli docs +update --api-version v2 --doc "<doc_id>" --command block_move_after \
+  --block-id "-1表示末尾，page_id表示开头，blk" \
+  --src-block-ids "block_a,block_b"
+```
+
+## 返回值
 
 ```json
 {
-  "success": true,
-  "doc_id": "文档ID",
-  "mode": "使用的模式",
-  "board_tokens": ["可选：新建画板 token 列表"],
-  "message": "文档更新成功（xxx模式）",

+      ]
+    },
+    "result": "success",
+    "updated_blocks_count": 3,
+    "warnings": []
+  }
 }
 ```
 
-如果本次 `docs +update` 创建了画板，响应会额外返回 `board_tokens`。在 CLI 的成功 JSON 输出里，后续编辑画板应读取 `data.board_tokens`。
+| 字段 | 说明 |
+|------|------|
+| `result` | `success` \| `partial_success` \| `failed` |
+| `updated_blocks_count` | 实际更新的 block 数量 |
+| `warnings` | 警告信息列表 |
+| `document.new_blocks` | 本次操作新增的 block 列表（如画板）。`block_id` 可用于后续精确编辑；`block_token` 是资源块 token（如画板）可交给 `lark-whiteboard` 等 skill 继续操作 |
 
-## 异步模式（大文档超时）
+## 典型工作流
 
-```json
-{
-  "task_id": "async_task_xxxx",
-  "message": "文档更新已提交异步处理，请使用 task_id 查询状态",
-  "log_id": "请求日志ID"
-}
-```
+### 精确 block 级更新
 
-## 错误
+1. **获取文档内容和 block ID**：
+   ```bash
+   lark-cli docs +fetch --api-version v2 --doc "<doc_id>" --detail with-ids
+   ```
 
-```json
-{
-  "error": "[错误码] 错误消息\n💡 Suggestion: 修复建议\n📍 Context: 上下文信息",
-  "log_id": "请求日志ID"
-}
-```
+2. **定位目标 block**：从返回的 XML 中找到要修改的 block 及其 `id` 属性
 
----
+3. **执行更新**：
+   ```bash
+   # 替换特定 block
+   lark-cli docs +update --api-version v2 --doc "<doc_id>" --command block_replace \
+     --block-id "blkcnXXXX" --content "<p>新内容</p>"
 
-# 使用示例
+   # 在某 block 后插入
+   lark-cli docs +update --api-version v2 --doc "<doc_id>" --command block_insert_after \
+     --block-id "blkcnXXXX" --content "<h2>追加的章节</h2>"
+   ```
 
-## append - 追加到末尾
+### 简单文本替换
+
+不需要 block ID，直接匹配替换：
 
 ```bash
-lark-cli docs +update --doc "文档ID或URL" --mode append --markdown "## 新章节
-
-追加的内容..."
+lark-cli docs +update --api-version v2 --doc "<doc_id>" --command str_replace \
+  --pattern "v1.0" --content "v2.0"
 ```
 
-## replace_range - 定位替换
+## 画板处理
 
-使用 `--selection-with-ellipsis`：
-```bash
-lark-cli docs +update --doc "文档ID" --mode replace_range --selection-with-ellipsis "## 旧标题...旧结尾。" --markdown "## 新标题
+> **`docs +update` 不能直接编辑已有画板的内容。** 本命令只能**新增**画板块；要修改已有画板，先用 `docs +fetch` 取到 `<whiteboard token="...">`，再切到 [`lark-whiteboard`](../../lark-whiteboard/SKILL.md) 用 `whiteboard +update` 写入。
 
-新的内容..."
-```
+画板的语法选型与插入示例见 [`lark-doc-style.md`](style/lark-doc-style.md) 的「画板语法与插入」章节。
 
-使用 `--selection-by-title`（替换整个章节）：
-```bash
-lark-cli docs +update --doc "文档ID" --mode replace_range --selection-by-title "## 功能说明" --markdown "## 功能说明
+## 最佳实践
 
-更新后的内容..."
-```
-
-## replace_all - 全文替换
-
-```bash
-lark-cli docs +update --doc "文档ID" --mode replace_all --selection-with-ellipsis "张三" --markdown "李四"
-```
-
-返回值包含 `replace_count` 字段，表示替换的次数。
-
-**注意**：
-- 与 `replace_range` 不同，`replace_all` 允许多个匹配
-- 如果没有找到匹配内容，会返回错误
-- `--markdown` 可以为空字符串，表示删除所有匹配内容
-
-## delete_range - 删除内容
-
-```bash
-lark-cli docs +update --doc "文档ID" --mode delete_range --selection-by-title "## 废弃章节"
-```
-
-注意：delete_range 模式不需要 `--markdown` 参数。
-
-## overwrite - 完全覆盖
-
-⚠️ 会清空文档后重写，可能丢失图片、评论等，仅在需要完全重建文档时使用。
-
-```bash
-lark-cli docs +update --doc "文档ID" --mode overwrite --markdown "# 新文档
-
-全新的内容..."
-```
-
-## 创建空白画板
-
-当用户要“新增空白画板”时，不要用 Mermaid 占位图；直接按 whiteboard 标签传 `--markdown`。
-
-自然语言请求示例：
-- “给我在这个文档末尾新增一个空白画板”
-
-```bash
-# 追加一个空白画板
-lark-cli docs +update --doc "文档ID" --mode append --markdown '<whiteboard type="blank"></whiteboard>'
-
-# 在指定内容后新增两个空白画板
-lark-cli docs +update --doc "文档ID" --mode insert_after --selection-with-ellipsis "有序列表" --markdown $'<whiteboard type="blank"></whiteboard>\n<whiteboard type="blank"></whiteboard>'
-```
-
-成功后，响应里的 `data.board_tokens` 就是新建画板的 token 列表；如果后续要继续编辑这些画板，直接使用这些 token。
-
----
-
-# 最佳实践
-
-## 重要：画板编辑
-
-> **⚠️ docs +update 不能编辑已有画板内容，但可以创建新的空白画板**
-
-画板编辑：详见 [SKILL.md](../SKILL.md#重要说明画板编辑)
-
-## 小粒度精确替换
-
-修改文档内容时，**定位范围越小越安全**。尤其是表格、分栏等嵌套块，应精确定位到需要修改的文本，避免影响其他内容。
-
-## 保护不可重建的内容
-
-图片、画板、电子表格、多维表格、任务等内容以 token 形式存储，**无法读出后原样写入**。
-
-**保护策略**：
-- 替换时避开包含这些内容的区域
-- 精确定位到纯文本部分进行修改
-
-## 分步更新优于整体覆盖
-
-修改多处内容时：
-- ✅ 多次小范围替换，逐步修改
-- ⚠️ 谨慎使用 `overwrite` 重写整个文档，除非你认为风险完全可控
-
-**原因**：局部更新保留原有媒体、评论、协作历史，更安全可靠。
-
-## insert 模式扩大定位范围时注意插入位置
-
-使用 `insert_before` 或 `insert_after` 时，如果目标内容重复出现，需要扩大 `--selection-with-ellipsis` 范围来唯一定位。
-
-**关键**：插入位置基于匹配范围的**边界**：
-- `insert_after` → 插入在匹配范围的**结尾**之后
-- `insert_before` → 插入在匹配范围的**开头**之前
-
-## 修复画板语法错误
-
-当 `docs +create` 或 `docs +update` 返回画板写入失败的 warning 时：
-1. warning 中包含 whiteboard 标签（如 `<whiteboard token="xxx"/>`）
-2. 分析错误信息，修正 Mermaid/PlantUML 语法
-3. 用 `--mode replace_range` 替换：`--selection-with-ellipsis` 使用 warning 中的 whiteboard 标签，`--markdown` 提供修正后的代码块
-4. 重新提交验证

-# 注意事项
-
-- **Markdown 语法**：支持飞书扩展语法，详见 [lark-doc-create](lark-doc-create.md) 工具文档
+- **精确操作优于全文覆盖**：使用 `block_replace`/`block_insert_after` 精确修改，避免 `overwrite` 全文覆盖
+- **str_replace 的匹配范围取决于格式**：
+  - **XML 模式（默认）**：`--pattern` 只支持**行内**匹配，不支持跨行 / 跨 block。段落、整块或容器级（列表、表格、分栏、引用块等）改动请改用 `block_replace` 指定 block_id 重建。
+  - **Markdown 模式**（`--doc-format markdown`）：`--pattern` 同时支持**行内和跨行**匹配，还支持 `前缀...后缀` 省略号语法（用 `...` 串联首尾片段匹配一大段内容），可以一次替换多行文本；但仍建议优先按最小片段匹配，跨 block 容器级重写仍优先用 `block_replace`，避免副作用。
+- **保护不可重建的内容**：图片、画板、电子表格等以 token 形式存储，替换时避开这些 block
+- **str_replace 的 replacement 支持富文本**：可以用行内标签 `<b>`、`<a>`、`<cite>`、`<latex>` 等替换普通文本为富文本
+- **同一 block 只能被 replace 一次**：多次修改同一 block 请合并为一次 block_replace
+- **block_delete 支持批量**：用逗号分隔多个 block_id 一次删除
+- **复杂结构重组**：将多个段落转换为 grid / table 等复杂布局时，分步操作比 overwrite 更安全：
+  1. 用 `block_insert_after` 在目标位置插入新的富文本结构
+  2. 用 `block_delete` 批量删除旧的 block
+  3. 这样可以保留文档中其他不相关的内容（图片、评论等）
+- **视觉丰富度**：插入或替换内容时，同样遵循 [`lark-doc-style.md`](style/lark-doc-style.md) 中的样式指南，主动使用结构化 block

+
+## 列表分组
+- 连续同类型列表项自动合并为一个 `<ul>` 或 `<ol>`
+- 嵌套子列表放在 `<li>` 内部
+- 新增列表项必须包在 `<ul>` 或 `<ol>` 内：

+- `<colgroup>` / `<col>` 定义列宽，紧跟 `<table>` 之后：`<col span="2" width="100"/>`
+- `<th>` / `<td>` 增加 `background-color` 和 `vertical-align`（top | middle | bottom）
+- 有表头时第一行在 `<thead>` 用 `<th>`，其余在 `<tbody>` 用 `<td>`
+- 合并单元格仅起始格输出 `colspan` / `rowspan`，被合并的格不出现
+
+# 六、美化系统
+- 颜色优先使用命名色，也可写 `rgb(r,g,b)` / `rgba(r,g,b,a)`。**基础色（6 色）**：gray, red, orange, yellow, green, blue
+  | 属性 | 支持的命名色 |                                                                                                                                                                                                        
+  |-|-|
+  | 文字颜色 `<span text-color>` | 基础色 |

+  | 按钮背景 `<button background-color>` | 同文字背景 |
+- 常用 emoji： 💡(默认)✅❌⚠️📝❓❗👍❤️📌🏁⭐
+
+# 七、**重要规则**
+## 转义规则：标签本身 **禁止转义**，只有标签内部的文本内容才需要转义
+
+**错误** ❌：`&lt;p&gt;内容&lt;/p&gt;`（把标签也转义了）
+**正确** ✅：`<p>A &amp; B 的对比：1 &lt; 2</p>`（标签保持原样，文本中的 `&` 和 `<` 才转义）
+
+转义字符表：
+- `<` → `&lt;`
+- `>` → `&gt;`
+- `&` → `&amp;`
+- `\n`（换行符） → `<br/>`

+# 从零创作工作流
+
+用户提供主题、需求或简要说明，需要生成一份新的飞书文档时，遵循本工作流。
+
+## 核心方法论 — Code-Act Loop
+
+通过自适应的 **Code-Act Loop** 驱动文档创作，而非固定模板式的工作流。每次任务都循环执行：
+
+1. **Plan（规划）** — 根据用户目标和文档当前状态，评估下一步该做什么
+2. **Execute（执行）** — 运行相应的 `lark-cli docs` 命令，或 **spawn** Agent 子任务并行推进
+3. **Observe（观察）** — 检查命令输出，验证正确性，核查样式是否达标
+4. **Iterate（迭代）** — 如需调整，回到 Plan 继续循环
+
+循环在文档达到质量标准且满足用户需求时结束。不要试图一次性产出完美内容——迭代打磨效果更好。根据用户实际需求灵活决定文档结构和版块，而不是套用固定模板。
+
+
+## 典型 Code-Act Loop 流程
+
+### 第一波 — 规划与骨架（串行）
+
+1. 分析用户需求：受众、目的、范围
+2. 设计大纲——每个 h1/h2 章节至少规划 1 个非文本 block
+3. `docs +create --api-version v2` 创建文档：标题 + 开头 `<callout>` + 骨架（各级标题 + 简短占位摘要）
+
+### 第二波 — 内容撰写（并行 Agent）
+
+4. Spawn Agent 并行撰写各章节。每个 Agent 需收到：
+   - 文档 token、负责的章节范围、期望的 block 类型
+   - `lark-doc-xml.md` 和 `lark-doc-style.md` 的完整路径（Agent 须先读取）
+   - 使用 `docs +update --command append` 或 `block_insert_after` 写入
+
+### 第三波 — 整合审查 + 画板意图识别（串行）
+
+5. `docs +fetch --detail with-ids` 获取文档，审查整体效果
+6. 评估样式达标（富 block 密度、元素多样性、连续 `<p>` 数量）
+7. **画板意图识别**：逐章节扫描，按 `lark-doc-style.md`「画板意图识别」表判断是否有段落适合用图表达。记录需要插图的章节及推荐的画板类型
+
+### 第四波 — 润色与图表（并行 Agent）
+8. Spawn Agent 定向改进：（结合 `lark-doc-style.md` 润色）
+   - **优先处理第三波识别出的画板需求**：简单图直接 `<whiteboard type="mermaid|plantuml">`，复杂图 spawn Agent 使用 **lark-whiteboard** skill
+   - 文字密集章节转为 `<table>`/`<grid>`/`<callout>`
+   - 主要章节间补充 `<hr/>`
+   - 本地图片使用 `docs +media-insert` 插入
+
+
+## Agent 子任务要求
+
+Spawn Agent 时必须提供：文档 token、章节范围（标题/block ID）、`lark-doc-xml.md` 和 `lark-doc-style.md` 路径、具体的 `docs +update` command 和 `--block-id`。
+
+章节较多时，先 `docs +create` 建骨架，再分段 `append` 追加，比一次性超长 `--content` 更可靠。

+# 文档样式指南
+
+创建或编辑文档时，必须遵循本指南，使用结构化 block 提升可读性和视觉层次。
+
+## 一、核心原则
+
+1. **结构优于文字**：能用结构化 block 表达的信息，不用纯文本段落
+2. **Front-load 结论**：文档以 `<callout>` 开头概括核心结论；每章节首段点明要旨
+3. **视觉节奏**：连续纯文本不超过 3 段；不同主题章节间用 `<hr/>` 分隔
+4. **最少惊讶**：同类信息使用同类元素，全篇风格统一
+
+## 二、元素选择指南
+
+涉及图表需求时，简单图用 `<whiteboard type="mermaid/plantuml">` 内嵌，复杂图使用 **lark-whiteboard** skill。
+
+| 场景 | 推荐方案 |
+|-|-|
+| 核心结论 / 摘要 / 注意事项 | `<callout>` + emoji + 背景色 |
+| 方案对比 / 优劣势 / Before vs After | `<grid>` 2 列分栏 |
+| 3+ 属性的结构化数据 / 指标表 | `<table>` + 表头背景色 |
+| 任务清单 / 检查项 | `<checkbox>` |
+| 代码片段 | `<pre lang="x" caption="说明">` |
+| 引用 / 公式 | `<blockquote>` / `<latex>` |
+| 操作入口 / 跳转链接 | `<button>` / `<a type="url-preview">` |
+| 简单流程图 / 时序图 / 状态机 / 甘特图 | `<whiteboard type="mermaid/plantuml">` |
+| 复杂架构图 / 数据图 / 思维导图 / 组织架构 | **lark-whiteboard** skill |
+
+### 画板意图识别
+
+撰写或审查每个段落/章节时，**必须判断该内容是否适合用图表达**。满足以下任一特征时，应使用画板而非纯文本：
+
+| 内容特征 | 信号词 / 模式 | 推荐画板类型 |
+|-|-|-|
+| 多步骤的操作流程或决策路径 | "先…然后…最后"、"步骤 1/2/3"、"如果…则…否则" | 流程图 / 泳道图 |
+| 系统或模块间的依赖与交互 | "调用"、"依赖"、"上游/下游"、"请求→响应" | 架构图 |
+| 上下级或从属关系 | "汇报给"、"下属"、"隶属"、"团队结构" | 组织架构图 |
+| 时间线或阶段演进 | "Q1/Q2"、"里程碑"、"阶段一→阶段二"、日期序列 | 时间线 / 里程碑 |
+| 因果分析或问题归因 | "根因"、"原因"、"导致"、"影响因素" | 鱼骨图 |
+| 两个及以上方案/对象的多维度对比 | "vs"、"方案 A/B"、"优劣"、"对比" | 对比图 |
+| 层级递进或优先级排序 | "基础→进阶→高级"、"L1/L2/L3"、"核心→外围" | 金字塔图 |
+| 数值趋势或周期变化 | 带数字的时间序列、"增长/下降"、百分比变化 | 折线图 / 柱状图 |
+| 漏斗或转化率 | "转化率"、"漏斗"、"从…到…留存" | 漏斗图 |
+| 发散或归纳的思维结构 | "要点"、"维度"、"分支"、多层嵌套列表 | 思维导图 |
+| 循环或飞轮效应 | "正循环"、"飞轮"、"闭环"、"A 驱动 B 驱动 C" | 飞轮图 |
+| 占比分布 | "占比"、"份额"、"分布"、百分比加总 ≈100% | 饼图 / 树状图 |
+
+**判断规则：**
+- 简单图（节点 ≤ 10、无需精细排版）→ `<whiteboard type="mermaid/plantuml">` 内嵌
+- 复杂图（节点 > 10、需自定义布局/样式、数据图表）→ spawn Agent 使用 **lark-whiteboard** skill
+
+### 画板语法与插入
+
+> **提醒：** `docs +update` 不能编辑已有画板内容；下面的语法都是**新增**画板块。修改已有画板需切到 [`lark-whiteboard`](../../../lark-whiteboard/SKILL.md)。
+
+#### 内嵌 Mermaid / PlantUML（首选）
+简单图直接用 `<whiteboard type="mermaid|plantuml">语法</whiteboard>`，作为 block 嵌入文档。
+
+#### DSL 画板（Mermaid / PlantUML 不够用时）
+需要架构图、对比图、组织架构等复杂结构时：
+1. 用 `<whiteboard type="blank"></whiteboard>` 通过 `docs +create` / `docs +update` 插入空白画板
+2. 从响应 `data.document.new_blocks` 中提取画板 `block_token`
+3. 切到 [`lark-whiteboard`](../../../lark-whiteboard/SKILL.md) skill 设计并上传 DSL
+
+更完整的协同流程见 [`lark-doc-whiteboard.md`](../lark-doc-whiteboard.md)。
+
+## 三、颜色语义
+
+全篇保持语义一致，同一语义必须使用同一颜色：
+
+| 语义 | emoji 前缀 | callout 背景色 | 文字色 |
+|-|-|-|-|
+| 信息、说明 | ℹ️ "说明：" | `light-blue` | `blue` |
+| 成功、推荐 | ✅ "推荐：" | `light-green` | `green` |
+| 警告 / 错误 / 风险 | ⚠️❌ | `light-red` | `red` |
+| 注意、待确认 | ❗"注意：" | `light-yellow` | `yellow` |
+| 中性、辅助 | — | `light-gray` | — |
+
+- 表头统一 `background-color="light-gray"`
+- 关键指标用 `<span text-color="green/red">` 突出，**必须同时用 ↑↓ 或 +/- 标注方向**（色觉无障碍）
+
+## 四、排版规范
+
+- 标题层级 ≤ 4 层，段落单段 ≤ 5 行，列表嵌套 ≤ 2 层，Grid ≤ 3 列
+- 文档开头用 `<callout>` front-load 结论；
+
+## 五、丰富度自检
+
+生成内容后必须自检，**未达标时主动优化**：
+
+| 指标 | 达标标准 |
+|-|-|
+| 富 block 密度 | ≥ 40%（非纯文本 block 数 ÷ 总 block 数） |
+| 元素多样性 | ≥ 3 种不同 block 类型 |
+| 连续纯文本 | ≤ 3 段连续 `<p>` |
+| 章节丰富度 | 每 h1/h2 ≥ 1 个非纯文本 block |
+| 开头 callout | 必须 |
+| 视觉节奏 | 不同主题章节间有 `<hr/>` |

+# 改写增强工作流
+
+用户提供已有文档链接或 token，需要改写、润色、补充或重排版时，遵循本工作流。
+
+## 核心方法论 — Code-Act Loop
+通过自适应的 **Code-Act Loop** 驱动文档改写，而非固定模板式的工作流。每次任务都循环执行：
+1. **Plan（规划）** — 根据用户目标和文档当前状态，评估下一步该做什么
+2. **Execute（执行）** — 运行相应的 `lark-cli docs` 命令，或 **spawn** Agent 子任务并行推进
+3. **Observe（观察）** — 检查命令输出，验证正确性，核查样式是否达标
+4. **Iterate（迭代）** — 如需调整，回到 Plan 继续循环
+
+## 核心原则：精准手术优于全量覆盖
+1. **精准手术**：只改用户指定的 block，不改其他 block。
+2. **全量覆盖**：如果用户明确要改整篇，才用 `overwrite` 命令。
+3. **保真约束**：改写时原文里的 `<cite type="user">`（@人）、`<cite type="doc">`（@文档）、`<img>`、`<source>`、`<whiteboard>`、`<sheet>`、`<bitable>`、`<synced_reference>` 等行内组件和资源块一律原样保留（含所有 token / user-id / doc-id 属性），不许替换成纯文本姓名、链接或占位符。
+
+## 工作流程
+
+### 第一波 — 分析 + 画板意图识别（串行）
+
+1. **选择读取范围**（节省上下文的关键）：
+   - 用户只改某一节 / 文档较大 → 先 `docs +fetch --api-version v2 --scope outline --max-depth 2` 拿目录，再 `docs +fetch --api-version v2 --scope section --start-block-id <目标标题id> --detail with-ids` 精读该节（`section` 会自动展开到下一个同级/更高级标题前，不用手动算结束 block id）
+   - 需要精确跨节区间 → `docs +fetch --api-version v2 --scope range --start-block-id xxx --end-block-id yyy`（或 `--end-block-id -1` 读到末尾）
+   - 用户只给了模糊关键词 → `docs +fetch --api-version v2 --scope keyword --keyword xxx --context-before 1 --context-after 1 --detail with-ids`
+   - 用户明确要改整篇 → `docs +fetch --api-version v2 --detail with-ids`
+   - 详见 [`lark-doc-fetch.md`](../lark-doc-fetch.md) "意图引导：选择正确的 --scope"
+2. 系统性评估：结构清晰度、富 block 密度（≥40%）、元素多样性（≥3种）、连续 `<p>` 是否超过 3 段、是否有开头 callout 和章节 `<hr/>`
+3. **画板意图识别**：逐章节扫描，按 `lark-doc-style.md`「画板意图识别」表判断哪些段落的信息适合用图表达。记录需要插图的章节（block ID）及推荐的画板类型
+4. 向用户简要说明改进计划（包含识别出的画板机会）
+
+### 第二波 — 定向改写（并行 Agent）
+
+5. Spawn Agent 在不重叠的章节上并行改进，各 Agent 收到文档 token 和特定 block ID：（见 `lark-doc-style.md`）
+   - 开头适当添加 `<callout>`、重组引言
+   - 纯文本转为 `<grid>`/`<table>`/`<whiteboard>`
+   - **对第一波识别出的画板候选段落**：简单图直接 `<whiteboard type="mermaid|plantuml">`，复杂图 spawn Agent 使用 **lark-whiteboard** skill
+   - 添加流程图、对比分栏等富 block
+
+### 第三波 — 验证（串行）
+
+5. 获取更新后文档局部内容，重新检查样式指标
+6. 未达标则定向修正，向用户呈现结果
+
+## Agent 子任务要求
+
+Spawn Agent 时必须提供：文档 token、章节范围（标题/block ID）、`lark-doc-xml.md` 和 `lark-doc-style.md` 路径、具体的 `docs +update` command 和 `--block-id`。
+
+**上下文节省提示**：Agent 如需在自己负责的章节内重新读取内容，优先用 `docs +fetch --api-version v2 --scope section --start-block-id <章节标题id>`（自动覆盖整节），或 `--scope range --start-block-id xxx --end-block-id yyy` 精确区间，只拉自己的章节，不要重复拉全文。

 - `--content` 接收结构化评论元素数组；`type` 支持 `text`、`mention_user`、`link`。为便于书写，`mention_user` / `link` 元素可以直接把用户 ID 或链接地址放在 `text` 字段中，shortcut 会转换成 OpenAPI 所需字段。
 - `type=text` 的评论文本不能直接包含 `<`、`>`；应优先传 `&lt;`、`&gt;`。shortcut 在发送前也会自动将 `<`、`>` 转义为 `&lt;`、`&gt;` 作为兜底。
-- 局部评论走 `locate-doc` 时，内部固定使用 `limit=10`。
-- 当 `locate-doc` 命中多处时，shortcut 会中止并提示用户继续收窄 `--selection-with-ellipsis`，不支持手动指定匹配序号。
 - 写入评论前会自动生成符合 OpenAPI 定义的请求体：
-- 统一接口：`POST /new_comments`
-- 统一字段：`file_type` + `reply_elements`
-- 全文评论：省略 `anchor`
-- 局部评论：传入 `anchor.block_id`
+  - 统一接口：`POST /new_comments`
+  - 统一字段：`file_type` + `reply_elements`
+  - 全文评论：省略 `anchor`
+  - 局部评论：传入 `anchor.block_id`
 - `--dry-run` 仅预览调用链和请求体，不会实际写入。
 - 如果需要更底层的控制，仍可改用 `lark-cli schema drive.file.comments.create_v2` + `lark-cli drive file.comments create_v2`。

+
+> **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。
+
+基于 Search v2 接口 `POST /open-apis/search/v2/doc_wiki/search`，以**用户身份**统一搜索云空间对象。
+
+和老的 `docs +search` 相比：
+
+- 把常用过滤条件全部**扁平化为独立 flag**（`--edited-since`、`--mine`、`--doc-types`、`--folder-tokens` 等），不再要求用户或 AI 手写嵌套 `--filter` JSON
+- 额外暴露了 4 个"我"维度：`my_edit_time`（我编辑过）、`my_comment_time`（我评论过）、`open_time`（我打开过）、`create_time`（文档创建时间）——直接对应用户自然语言里的"最近我编辑过的"、"我评论过的"等表达
+- 自动处理 `my_edit_time` / `my_comment_time` 的小时级聚合（服务端存储粒度）：亚小时输入会向整点 snap，并在 stderr 打出提示
+- `--mine` 一键从当前登录用户的 open_id 填 `creator_ids`，不必再先去查 contact
+
+> **资源发现入口统一**：`drive +search` 同样返回 `SHEET` / `Base` / `FOLDER` 等全部云空间对象，不只是文档 / Wiki。用户说"找一个表格"、"找报表"、"最近打开的表格"时，也从这里开始；定位后再切到对应业务 skill（如 `lark-sheets`）做对象内部操作。

+
+## 参数
+
+### 核心
+
+| 参数 | 必填 | 说明 |
+|---|---|---|
+| `--query <text>` | 否 | 搜索关键词；支持服务端高级语法（`intitle:`、`""`、`OR`、`-`）。空字符串或省略表示纯 filter 浏览 |
+| `--page-size <n>` | 否 | 每页数量，默认 15，最大 20。超过 20 自动 clamp；非正数（≤0）回落 15；**非数字值直接返回 validation 错误** |
+| `--page-token <token>` | 否 | 上一次响应里的 `page_token`，用于翻页 |
+| `--format` | 否 | `json`（默认）/ `pretty` |
+
+### 身份（creator 维度）
+
+| 参数 | 映射 | 说明 |
+|---|---|---|
+| `--mine` | `creator_ids = [当前用户 open_id]` | bool。一键"我创建的"；从当前登录用户身份（`runtime.UserOpenId()`）解析 open_id，取不到直接报错（提示运行 `lark-cli auth login`） |
+| `--creator-ids ou_x,ou_y` | `creator_ids = [...]` | 显式 open_id 列表，逗号分隔；**与 `--mine` 互斥** |
+
+### 时间维度（每个维度一对 since/until）
+
+| 参数 | 映射 API 字段 | 是否小时 snap |
+|---|---|---|
+| `--edited-since` / `--edited-until` | `my_edit_time.start` / `.end` | ✅ start 向下取整，end 向上取整 |
+| `--commented-since` / `--commented-until` | `my_comment_time.start` / `.end` | ✅ 同上 |
+| `--opened-since` / `--opened-until` | `open_time.start` / `.end` | ❌ 原样透传 |
+| `--created-since` / `--created-until` | `create_time.start` / `.end` | ❌ 原样透传（文档创建时间，非"我"语义）|
+
+### 作用域
+
+| 参数 | 映射 | 说明 |
+|---|---|---|
+| `--doc-types docx,sheet` | `doc_types` | 逗号分隔。允许值：`doc,sheet,bitable,mindnote,file,wiki,docx,folder,catalog,slides,shortcut` |
+| `--folder-tokens fld_a,fld_b` | `folder_tokens`（仅 doc_filter） | 存在时只发 `doc_filter`；**与 `--space-ids` 互斥** |
+| `--space-ids sp_x` | `space_ids`（仅 wiki_filter） | 存在时只发 `wiki_filter`；**与 `--folder-tokens` 互斥** |
+| `--chat-ids oc_x` | `chat_ids` | 逗号分隔 |
+| `--sharer-ids ou_x` | `sharer_ids` | 逗号分隔，open_id |
+
+### 其他
+
+| 参数 | 映射 | 说明 |
+|---|---|---|
+| `--only-title` | `only_title: true` | bool |
+| `--only-comment` | `only_comment: true` | bool |
+| `--sort <value>` | `sort_type`（转大写枚举） | 允许值：`default, edit_time, edit_time_asc, open_time, create_time` |
+
+> `--sort`：CLI 只暴露服务端**正式支持**的 5 个值。服务端 enum 里 `CREATE_TIME_ASC` 协议标注"暂不支持"，`ENTITY_CREATE_TIME_ASC` / `ENTITY_CREATE_TIME_DESC` 已废弃，CLI 直接不放出来，传了会被 cobra enum 校验拒掉。
+
+## 时间值格式
+
+所有 `--*-since` / `--*-until` 共用：
+
+| 输入 | 含义 |
+|---|---|
+| `7d` / `30d` | N 天前的当前时刻 |
+| `1m` | 30 天前（固定 30 天，**不是**日历月）|
+| `3m` / `6m` | 90 / 180 天前 |
+| `1y` | 365 天前 |
+| `2026-04-01` | 本地时区 00:00:00 |
+| `2026-04-01 10:00:00` / `2026-04-01T10:00:00` | 本地时区具体时刻 |
+| `2026-04-01T10:00:00+08:00` | RFC3339 带时区 |
+| `1743523200`（≥ 10 位纯数字）| Unix 秒直接透传 |
+
+> `m` 绑定 month（30 天），不支持 minute——因为 `my_edit_time` / `my_comment_time` 在服务端是小时聚合，分钟粒度没意义。
+
+## 小时聚合（my_edit_time / my_comment_time）
+
+服务端对这两个字段按整点聚合，亚小时输入会被 CLI 向整点对齐：
+
+```text
+start: floor 到整点   16:23:45 → 16:00:00
+end:   ceil  到整点   16:23:45 → 17:00:00
+```
+
+发生对齐时，stderr 会打印一条 notice，例如：
+
+```text
+notice: my_edit_time has hour-level granularity server-side;
+        start 2026-04-22 16:23:00 → 2026-04-22 16:00:00
+        end   2026-04-22 16:28:00 → 2026-04-22 17:00:00
+```
+
+stdout 的 JSON 输出不受影响。`open_time` / `create_time` 不做 snap。
+
+## 输出
+
+- `--format json`（默认）：`{ total, has_more, page_token, results: [...] }`；所有 `*_time` 字段递归补 `*_time_iso`
+- `--format pretty`：4 列 table —— `type | title | edit_time | url`
+- `title_highlighted` / `summary_highlighted` 可能包含 `<h>` / `<hb>` 高亮标签，客户端对比前需先剥离
+
+> **注意**：返回体里的 `total` 字段不够准确（官方确认，仅供参考）。需要精确统计的场景，按实际 `results` 做去重和累加，不要把 `total` 当结果数承诺。
+
+## 决策规则
+
+- **和 `docs +search` 的选择**：优先使用 `drive +search`（本指令），不要再用 `docs +search`。`docs +search` 进入维护期、后续会下线。
+- **身份快捷方式**：只要用户说"我创建的"，直接 `--mine` 即可，不需要先查 contact 拿 open_id。
+- **时间维度选择**：
+  - "我编辑的"、"我修改的" → `--edited-since` / `--edited-until`
+  - "我评论的"、"我回复过的" → `--commented-since` / `--commented-until`
+  - "我看过的"、"我打开过的"、"最近看过的" → `--opened-since` / `--opened-until`
+  - "创建于"、"新建的"（文档整体维度，与"我"无关）→ `--created-since` / `--created-until`
+- **作用域选择**：
+  - "某个文件夹下" → `--folder-tokens`（doc-only）
+  - "某个 wiki 空间下" → `--space-ids`（wiki-only）
+  - 两者不能同时使用，混用会报错
+- **身份 flag 互斥**：`--mine` 和 `--creator-ids` 不要同时传，会直接报错。"我和张三创建的" 用 `--creator-ids ou_me,ou_zhangsan`（需要先拿到自己 open_id，但这种场景少见）。
+- **实体补全**：
+  - 用户说"某个群里"，先用 `lark-im` 查 `chat_id`
+  - 用户说"某人创建/分享的"（非自己），先用 `lark-contact` 查 open_id，再填 `--creator-ids` / `--sharer-ids`
+- **查询语义下推**：`--query` 支持的服务端高级语法（`intitle:`、`""`、`OR`、`-`）优先使用，不要先模糊搜再在客户端二次过滤。
+- **时间表达**：
+  - 模糊相对时间（"最近半年"、"过去 30 天"、"最近一周"）→ `--*-since 6m` / `--*-since 30d` / `--*-since 7d`，不展开成 ISO 时间
+  - **日历表达**（"上个月"、"上周"、"本月"、"前年"、"今年 3 月"等明确日历单位）→ **必须算出绝对 `YYYY-MM-DD` 边界**（如"上个月" = 上一个日历月的 1 号 → 当月 1 号），**不要近似成 `1m`/`2m`**：CLI 里 `m` 是固定 30 天、`y` 固定 365 天，跟日历差 0-3 天，月末月初尤其容易偏出去
+  - 绝对日期 → 直接 `YYYY-MM-DD` 或 RFC3339
+- **分页策略**：默认只返回第一页，并说明 `has_more` 和下一页命令。只有用户明确要"全部 / 全量 / 继续翻"才继续。单轮翻页上限 5 页。
+- **原始返回**：用户要求"原始数据"、"接口返回"时用 `--format json`，不做客户端精确过滤或摘要重写。
+
+## 权限
+
+| 操作 | 所需 scope |
+|---|---|
+| 搜索云空间对象（文档 / Wiki / 表格等资源发现） | `search:docs:read` |
+
+## 常见错误
+
+| code | 含义 | 处理 |
+|---|---|---|
+| `99992351` | `--creator-ids` / `--sharer-ids` 里有 open_id 超出**应用的通讯录可见范围**，服务端拒绝识别 | 让管理员在开发者后台把这些用户加进应用的"通讯录可见性"授权里；或把超出范围的 open_id 从参数里去掉。这和 `search:docs:read` scope 不是一回事 —— 是"应用能看见哪些人"而不是"应用能调用哪个接口" |
+
+## 时间范围自动裁剪（`--opened-*` 专有）
+
+服务端对 `open_time` 过滤**每次请求最多支持 3 个月**（90 天）窗口。其他三个时间维度（`--edited-*` / `--commented-*` / `--created-*`）**不受影响**。
+
+CLI 在发请求前会检查 `--opened-since` 到有效 `--opened-until`（没传则取 `now`）的跨度：
+
+| 跨度 | 行为 |
+|---|---|
+| ≤ 90 天 | 原样透传 |
+| 91 ~ 365 天 | **自动裁剪**到"最近一个 90 天 slice"，stderr 打一条 notice 列出所有剩余 slice 的 `--opened-since` / `--opened-until` 参数值 |
+| > 365 天 | 直接报 validation 错，要求缩小范围或自行拆分多次查询 |
+
+Notice 示例（用户原本要求"过去 8 个月"，会被拆成 3 个 slice）：
+
+```text
+notice: --opened-* window spans 240 days (~8 months), exceeds the server-side 3-month (90-day) limit.
+        this query was narrowed to the most recent slice; 3 slices total:
+          [slice 1/3 current] --opened-since 2026-01-24T21:54:02+08:00 --opened-until 2026-04-24T21:54:02+08:00
+          [slice 2/3]         --opened-since 2025-10-26T21:54:02+08:00 --opened-until 2026-01-24T21:54:02+08:00
+          [slice 3/3]         --opened-since 2025-08-27T21:54:02+08:00 --opened-until 2025-10-26T21:54:02+08:00
+        pagination: paginate within a slice via --page-token using that slice's --opened-since / --opened-until values verbatim (NOT the original relative time like '1y' / '8m' — relative times re-resolve against time.Now() and would mismatch the page_token); switch to the next slice's --opened-* flags only after has_more=false, and do not carry --page-token across slices.
+```
+
+### Agent 看到 notice 时的处理
+
+**标准流程（分页 × slice 的先后顺序）：**
+
+1. **跑 slice 1**（本次请求已自动裁剪到这个窗口），把结果呈现给用户
+2. **先在当前 slice 内翻页**：返回的 `has_more = true` 且用户想看更多时，把 `--opened-since` / `--opened-until` 改成 notice 里 `[slice 1/N current]` 行给出的**具体时间值**（**不要继续用原始的 `--opened-since 1y` 这种相对值**——CLI 每次调用都按 `time.Now()` 重算窗口，相对值 + `--page-token` 一起跑会让 page_token 绑到一个漂移的窗口上、结果静默失真），加 `--page-token` 继续翻，直到 `has_more = false`
+3. **再切换到下一个 slice**：当前 slice 翻完后，如果用户还要"更老的"，用 notice 里列的 slice 2 的 `--opened-since` / `--opened-until` 值，**其他 flag（`--query`、`--doc-types`、`--page-size`、`--sort`……）保持原样，`--page-token` 不带**，重新发请求
+4. **依次递推**：slice 2 翻完后切 slice 3，以此类推
+5. 用户只对最近一段感兴趣时，跳过第 3 步及以后 —— 避免无意义的 API 调用
+
+> `--page-token` 只在单 slice 上下文内有效；切 slice 时不要把上一个 slice 的 `page_token` 带过去。
+
+### 注意事项
+
+- `--sort` 在**单 slice 内部**是正确的。跨 slice 的全局 sort（例如"过去一年我打开过的，按 edit_time desc 排"）不被 CLI 保证，需要 agent 自行拉完多个 slice 后在客户端 re-sort 再呈现
+- 裁剪只改 request 发出去的 `open_time` 范围，`--query` / 其他 filter 不动
+- 最后一个（最老的）slice 常常不足 90 天，这是正常的截断

+# mail +decline-receipt
+
+> **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。
+
+关闭收到邮件的已读回执请求 banner，**但不向发件人发送回执**。**本命令仅在对方邮件请求了已读回执（`READ_RECEIPT_REQUEST` 标签，系统 ID `-607`）时使用**。对齐飞书客户端上已读回执 banner 右侧的"不发送"按钮。
+
+本 skill 对应 shortcut：`lark-cli mail +decline-receipt`。
+
+## 使用时机
+
+决策分支：拉信看到 `READ_RECEIPT_REQUEST` 标签 → **必须先问用户**：
+
+- 用户愿意告知对方"已读" → `+send-receipt`
+- 用户不愿意告知但想消掉提示 → `+decline-receipt`（本命令）
+- 用户既不想回执也不关心 banner → 什么都不做
+
+## 命令
+
+```bash
+# 标准用法
+lark-cli mail +decline-receipt --message-id <message-id>
+
+# 指定邮箱（公共邮箱场景）
+lark-cli mail +decline-receipt --mailbox shared@example.com --message-id <message-id>
+
+# Dry Run（不真改）
+lark-cli mail +decline-receipt --message-id <message-id> --dry-run
+```
+
+## 参数
+
+| 参数 | 必填 | 默认 | 说明 |
+|------|------|------|------|
+| `--message-id <id>` | 是 | — | 请求了已读回执的原邮件 message ID |
+| `--mailbox <email>` | 否 | `me` | 邮件归属的邮箱 |
+| `--dry-run` | 否 | — | 仅打印请求，不执行 |
+
+> 注意本命令没有 `--yes` —— 它只是移除一个本地 label，不对外发信，Risk 级别是 `write` 而非 `high-risk-write`。
+
+## 行为细节
+
+- 先 `fetchFullMessage` 拉一遍原邮件校验：若 `label_ids` 中不含 `READ_RECEIPT_REQUEST`（也不含数字 `-607`），直接返回 `already_cleared: true`，**不发请求**，幂等。
+- 标签存在时调 `PUT /user_mailboxes/<mailbox>/messages/<id>/modify`（`user_mailbox.message.modify`），body `{"remove_label_ids":["READ_RECEIPT_REQUEST"]}`。
+- **不发任何外发邮件**：等价于飞书客户端"不发送"按钮——只清除本地标签，发件人不会收到任何通知。
+
+## 返回值
+
+标签已清除（无副作用）：
+
+```json
+{
+  "ok": true,
+  "data": {
+    "message_id":             "原邮件 message ID",
+    "decline_receipt_for_id": "原邮件 message ID",
+    "declined":               false,
+    "already_cleared":        true
+  }
+}
+```
+
+本次真正移除了标签：
+
+```json
+{
+  "ok": true,
+  "data": {
+    "message_id":             "原邮件 message ID",
+    "decline_receipt_for_id": "原邮件 message ID",
+    "declined":               true
+  }
+}
+```
+
+## 典型场景
+
+### 场景 1：用户选择不发回执
+
+```bash
+# 1. 拉信
+lark-cli mail +message --message-id msg-1 --format json | jq '.data.label_ids'
+# → ["UNREAD", "READ_RECEIPT_REQUEST"]
+
+# 2. 向用户提示：
+#    "这封来自 alice@example.com 的邮件请求已读回执。主题：《周报》。
+#     要不要回一封告诉对方你已阅读？
+#     也可以选择：不发送回执，但关闭这条提示。"
+
+# 3. 用户选了"不发送" → 
+lark-cli mail +decline-receipt --message-id msg-1
+```
+
+### 场景 2：幂等重跑
+
+```bash
+# 第一次移除标签
+lark-cli mail +decline-receipt --message-id msg-1
+# → {"declined": true}
+
+# 再跑一次 —— 不会报错，也不会再发 modify 请求
+lark-cli mail +decline-receipt --message-id msg-1
+# → {"declined": false, "already_cleared": true}
+```
+
+## 不要这样做
+
+- ❌ 替用户自动 decline —— 违反隐私规则的对称面：不回执的"沉默"也属于用户选择
+- ❌ 拿 `+decline-receipt` 当"标记已读"——它只移 `READ_RECEIPT_REQUEST` 一个标签，不改 `UNREAD`
+- ❌ 在没有 `READ_RECEIPT_REQUEST` 标签的邮件上调用 —— 虽然幂等返回 `already_cleared`，但多发一次 GET 无意义
+
+## 相关命令
+
+- `lark-cli mail +send-receipt` — 同意回执（发一封系统样式的已读回执邮件）
+- `lark-cli mail +message` — 拉单封邮件（在 `label_ids` 里检查 `READ_RECEIPT_REQUEST`）
+- `lark-cli mail +send --request-receipt` — 反向：**请求**别人回执
