Tools mostly have distinct purposes, but get_unread_emails and list_recent_emails both list emails (with different filters), and read_email vs summarize_email both fetch a specific email. Descriptions clarify the differences, so confusion is unlikely.

All tools follow a consistent verb_noun pattern in snake_case (e.g., get_unread_emails, mark_as_read, send_email). Minor modifiers like 'unread' or 'recent' do not break the convention.

8 tools is well within the ideal 3-15 range and covers a balanced set of email operations without unnecessary bloat. Each tool has a clear purpose.

Core email workflows (list, read, search, send, reply, mark read) are covered. Missing operations like delete, archive, or attachment handling are minor gaps that agents can work around for most use cases.
