Cloud mode delivers over SMTP and returns the new message ID; local mode sends through Mail.app, which only sends plain text and returns no ID. There is no draft step, so the message goes out as soon as the tool runs.search-emailsSearches one mail folder (inbox by default) by free text, sender, subject and unread state; the filters combine as AND. Results carry the same summary fields as list-emails, including the ref handle that read-email and mark-as-read take.mark-as-readMarks an email as read or unreadlist-foldersLists all email folderslist-eventsLists upcoming calendar events within a look-ahead window (30 days by default, up to 365). Each event carries its title, start and end times, and the ref handle that update-event and delete-event take as their eventUrl argument.create-eventCreates a new calendar eventupdate-eventUpdates an existing calendar event. Only the fields you pass are changed.
