list_emails and search_emails both return email lists, but search_emails adds filtering criteria while list_emails is purely chronological. get_email and send_email target distinct resources and actions, making overall selection clear.

All tools follow a consistent verb_noun pattern (list_emails, search_emails, get_email, send_email). The convention is predictable and easy to scan.

Core read and send operations are covered, but common email lifecycle actions like delete, mark read/unread, move, and list folders are missing. Agents can handle simple tasks but will hit dead ends for routine mailbox management.
