Send WhatsApp messages to other people or search/sync WhatsApp history via the wacli CLI (not for normal user chats). Use when the user asks to send a WhatsApp message, text someone on WhatsApp, search WhatsApp chat history, sync WhatsApp conversations, backfill message history, or forward a file via WhatsApp to a third party.
Use wacli only when the user explicitly asks you to message someone else on WhatsApp or when they ask to sync/search WhatsApp history.
Do NOT use wacli for normal user chats; Otto routes WhatsApp conversations automatically.
If the user is chatting with you on WhatsApp, you should not reach for this tool unless they ask you to contact a third party.
