Scored across 5 tools
Each tool targets a distinct calculation: single-sale fee, multi-unit payout, reference rates, reverse target pricing, and cross-platform comparison. However, fee and payout overlap on the core 'fees and net for a sale' purpose, so an agent could occasionally misselect between them without careful reading.
Names are all lowercase but mix conventions: fee, payout, and platforms are bare nouns, price_for_target uses snake_case, and compare is a bare verb. The set is readable but lacks a predictable pattern.
Five tools is well-scoped for a fee-calculation domain, with each tool earning its place and no redundant filler.
The surface covers the full lifecycle: lookup rates, compute fee/net for one sale, aggregate payout for multiple units, reverse-solve a target price, and compare across platforms. Gaps are minor, such as no regional/non-USD or historical rate support, which is excusable given the stated US/USD scope.
