Scored across 11 tools
Each tool has a distinctly separate purpose: archiving, deleting, flagging, listing, marking read/unread, moving, reading, searching, and unflagging. No overlap in functionality.
All tool names follow a consistent verb_noun pattern in snake_case (e.g., archive_emails, delete_emails, list_folders). No mixing of conventions.
11 tools is an appropriate number for an email management server, covering core operations without being overly numerous or sparse.
The tool set covers reading, searching, and organizing emails, but lacks tools for composing, sending, or drafting emails, which are significant missing operations for an email server.
