fix(whatsapp): skip reply prefix in bot mode#3931
Merged
Conversation
The WhatsApp bridge prepends '⚕ *Hermes Agent*\n────────────\n' to every outgoing message. In self-chat mode this is necessary to distinguish the bot's responses from the user's own messages. In bot mode the messages already come from a different number, making the prefix redundant and cluttered. Now only prepends the prefix when WHATSAPP_MODE is 'self-chat' (the default). Bot mode messages are sent clean.

Summary
The WhatsApp bridge prepends
⚕ *Hermes Agent*\n────────────\nto every outgoing message. In self-chat mode (where bot and user share the same number), this is necessary to tell messages apart. In bot mode (separate number), it's redundant — the sender identity is already clear from the phone number.Fix
formatOutgoingMessage()inscripts/whatsapp-bridge/bridge.jsnow skips the prefix whenWHATSAPP_MODEis notself-chat.Self-chat mode (default): prefix still applied, echo detection still works.
Bot mode: clean messages, no prefix.
Users can still override with
WHATSAPP_REPLY_PREFIXenv var regardless of mode.Change
