The four raw-data tools and the synthesized-answer tool are explicitly differentiated by their descriptions, and simulation/payment-marker tools have distinct roles. The only overlap is between complete_household_profile and update_household_profile, both of which save profile facts; their contexts differ but an agent could occasionally confuse them.

All tool names use snake_case with a clear verb_noun style (get_*, complete_*, update_*, mark_*, simulate_*). The pattern is consistent throughout, with no mixing of conventions.

Nine tools is well-scoped for a household finance advisory server: four raw-data retrievals, one synthesized answer, two profile writes, one simulation, and one payment marker. Each tool earns its place.

The set covers profile updates, raw data retrieval, budget answers, simulation, and marking a bill paid. Minor gaps exist: there is no tool to persist a simulated payment change or to directly add/update obligation details, but core advisory workflows are covered.
