Everything from the last N hours, grouped by chat. The catch-up tool. `include_system` adds WhatsApp's own notices, `types` narrows to one or more message types, `include_previews` attaches a small image of each photo, `compact` halves it for a routine catch-up.
get_unanswered
Who is waiting on the user: chats whose last word is theirs and asks for something, with the ask quoted. Groups only when the user was @-mentioned or replied to.
set_contact_note
Remember something about a person, on this machine only; it then shows next to their name everywhere.
mark_handled
Take a chat off `get_unanswered` until the other side writes again. Nothing changes on WhatsApp.
get_stories
The stories (status updates) received in the last day, by author, with previews on request. They show nowhere else.
wait_for_messages
Block up to 55 s until a message arrives, then return it with a cursor for the next call. `addressed_to_me` wakes only for direct messages, @-mentions and replies.
search_messages
Text search across the locally held messages; `since`, `until` and `from` narrow it.
