Each tool has a distinct primary purpose: registry lookup by BIC/identifier, IBAN validation, and synthetic test data generation. The only minor overlap is that validate_ibans also returns bank/BIC data on paid plans, which slightly blurs the line with lookup_bank, but the core intents are clearly separable.

All three tools follow a clean verb_noun snake_case pattern: lookup_bank, validate_ibans, generate_test_ibans. The convention is uniform and self-explanatory with no mixed styles.

Three tools is on the lean side but reasonable for a focused IBAN/bank-intelligence utility. Each tool earns its place (validate, lookup, generate), though the surface is thin enough that it borders on minimal.

Core workflows—validating IBANs, resolving bank records, and generating test data—are covered, giving a coherent lifecycle for the domain. Minor gaps exist, such as IBAN parsing/component extraction or standalone BIC validation, but agents can work around these.
