Most tools target distinct actions: register, send, read, poll for updates, update status, list, board overview, and thread view. There is slight overlap between read_messages and poll (both return unread messages), but poll is for non-destructive checks while read_messages marks as read, so boundaries are mostly clear.

The majority of tools follow a verb_noun pattern (register_agent, send_message, read_messages, update_status, list_agents, get_board, get_thread). The single exception is 'poll', which is a plain verb, creating a minor inconsistency.

Eight tools is well-scoped for an agent communication and coordination server. Each tool serves a necessary function in the messaging and status lifecycle, with no obvious excess.

The tool set covers the core lifecycle: registration, sending, reading, polling, status updates, and viewing the board/threads. Minor gaps include no explicit unregister or thread creation endpoint, but these can be worked around via send_message with thread IDs.
