+description: 飞书/Lark 聚合能力入口：当用户需求涉及本文件列出的任一飞书能力时使用；仅负责选择并加载已安装到本 suite 的 lark-* 子能力，不替代具体子能力的操作细节。
+metadata:
+  requires:
+    bins:
+      - lark-cli
+---
+
+# Lark Suite
+
+你是飞书/Lark 能力的聚合路由层。你的职责是先判断用户要使用哪个 `lark-*` 子能力，再读取并遵循对应子能力的说明。
+
+`lark-suite` 不直接承载具体 API 操作步骤。除非对应子能力已被读取，否则不要仅根据本文件拼命令、猜参数或执行复杂操作。
+
+## 使用流程
+
+1. 根据用户意图从下方路由表选择一个或多个子能力；即使用户尚未提供链接、ID 或具体工作表，也先选择能力，再由子能力询问缺失信息。
+2. 读取对应子能力说明，优先使用 `references/subskills/<skill-name>/SKILL.md`。
+3. 如果目标能力没有出现在本文件中，不代表当前环境不可用；检查是否存在相关的独立 `lark-*` skill。
+4. 如果已选中的子能力说明列出必读、前置或继续阅读的文件，只读取该子能力当前任务所需的前置文件；不要读取无关子能力。
+5. 按目标子能力的说明执行；认证、租户、身份、权限和通用排障优先遵循 `lark-shared`。
+
+`lark-shared` 是共享基础能力，不作为 `--collected-skills` 的可选项。为了保证 suite 内子能力可用，hybrid 布局会同时保留顶层 `lark-shared`，并在 `lark-suite/references/subskills/lark-shared/SKILL.md` 中维护一份副本。
+
+多步任务可以组合多个子能力，但每一步都应由具体子能力驱动。例如“查联系人并发消息”先用 `lark-contact` 解析身份，再用 `lark-im` 发消息。
+
+## 能力路由
+
+根据用户意图从以下条目选择对应子能力；如果一个任务涉及多个能力，按实际操作顺序逐步读取并使用对应子能力。
