+## Channel Support
+
+OCM is a local UI for OpenClaw. The core features (agent trees, routing, models/auth, ops, backups) are channel-agnostic.
+
+Current focus:
+
+- **Telegram** — best supported and most documented today
+- **Discord** — supported (recommended for private channels/threads + strict allowlist)
+- **Feishu / Lark (飞书)** — supported (Beta; enterprise-oriented setup)
+- **WhatsApp** — **not supported for sub-agent workflows** (platform constraints make reliable multi-agent isolation + routing hard)
+
 ## Telegram Workflow & Safety
 
 OCM is designed primarily for **Telegram-based OpenClaw workflows**:

+## Q: 为什么 OCM 暂时不支持 WhatsApp 的 sub-agent 工作流？
+
+WhatsApp 在 bot/group 自动化能力上有较多平台限制（接入方式、权限与路由粒度、稳定性等）。
+
+OCM 的 sub-agent 模式依赖清晰的“会话边界 + 路由 + 最小权限”来保证安全和可维护性。
+因此我们目前不把 WhatsApp 作为 sub-agent 的推荐渠道，暂不支持该模式。
+
+如果未来支持 WhatsApp，更可能是 **单聊通知/轻量交互** 方向，而不是多 sub-agent 的群聊拓扑。

 - Group Privacy = OFF
 
+## Discord safety
+
+Recommended defaults (especially for open-source / shared servers):
+
+- Prefer **private channels / private threads** as agent boundaries.
+- Use a strict **allowlist** of channels/threads the bot is allowed to respond in.
+- Apply **least-privilege** Discord permissions when installing the bot (only what you need).
+- Avoid running memory-enabled agents in public channels.
+
+## Feishu / Lark (飞书) safety
+
+Feishu is enterprise-oriented and typically requires more permission setup:
+
+- Request the smallest permission scope possible for your app/bot.
+- Treat group visibility as a security boundary (who can see the bot’s outputs).
+- Prefer separate chats/spaces for different agents to reduce context bleed.
+
+## WhatsApp note
+
+WhatsApp is not a recommended target for sub-agent topology workflows. Constraints in bot/group automation make reliable multi-agent isolation + routing difficult.

+OCM is expanding beyond Telegram:
+
+- **Discord**: recommended to use **private channels/threads** as boundaries + strict allowlist routing.
+- **Feishu / Lark (飞书)**: supported (Beta); enterprise-oriented setup with stronger permission/visibility considerations.

+### 其他渠道说明
+
+OCM 正在扩展 Telegram 之外的渠道支持：
+
+- **Discord**：建议用**私密频道/私密 thread**作为边界，并启用严格 allowlist 路由。
+- **飞书 / Lark**：支持（Beta）；企业协作场景更强，但权限/可见性边界需要更谨慎。
+- **WhatsApp**：不适合做 sub-agent 群聊拓扑（暂不支持）。
