Scored across 7 tools
Each tool targets a distinct calendar concept: checking business days, adding/counting them, finding gotobi dates, month-end info, fiscal periods, and holiday lists. No two tools have overlapping purposes, and descriptions clearly distinguish edge cases.
Most tools use a verb_noun pattern (is_business_day, add_business_days, list_holidays), but a few deviate into noun phrases (month_end_info, fiscal_period) or adjective_noun (next_gotobi). All names are lowercase snake_case, so the inconsistency is minor and readability is preserved.
Seven tools is well within the ideal 3-15 range and matches the server's focused scope. Each tool serves a distinct core function for Japanese business calendar operations, with no redundant or unnecessary additions.
The surface covers primary business-day calculations, holiday listing, gotobi dates, month-end adjustments, and fiscal periods. Minor gaps include explicit next/previous business-day convenience functions and management of company-specific holidays, but existing tools can work around these.
