 Admin status is set inside the group (Telegram UI). Admin bots always receive all
 group messages, so use admin if you need full visibility.
 
+### Bot-to-bot messages (Telegram limitation)
+**Telegram Bot API does not deliver messages sent by other bots** — even if:
+- Your bot is a group admin
+- Privacy mode is disabled
+
+This is a [Telegram Bot API limitation](https://core.telegram.org/bots/faq#why-does-my-bot-not-see-messages-from-other-bots) designed to prevent feedback loops. Your bot cannot read messages from other bots in groups or DMs.

+If you need bot-to-bot communication, use out-of-band methods (HTTP calls, queues, or databases) instead of relying on Telegram group messages.

 ## How it works (behavior)
 - Inbound messages are normalized into the shared channel envelope with reply context and media placeholders.
 - Group replies require a mention by default (native @mention or `agents.list[].groupChat.mentionPatterns` / `messages.groupChat.mentionPatterns`).
