Scored across 11 tools
Most tools map to a single distinct action: read, delete, archive, flag, move, etc. The only mild overlap is between list_emails and search_emails, but their descriptions distinguish recent folder listing from filtered search.
All tool names follow a clear snake_case verb_noun pattern, such as list_emails, delete_emails, and move_emails. Paired operations like mark_as_read/mark_as_unread and flag_emails/unflag_emails reinforce the predictable naming scheme.
Eleven tools is a well-scoped set for an email management server. Each tool covers a necessary common operation without bloating the surface with redundant aliases or overly granular actions.
The set thoroughly covers reading, searching, deleting, archiving, moving, and flagging emails, but it omits sending/composing email entirely, which is a core Yahoo Mail workflow. It also lacks folder creation or renaming, leaving obvious lifecycle gaps.
