Scored across 5 tools
Each tool targets a distinct operation: email verification, phone verification, balance checking, credit top-up, and tool listing. There is no overlap or ambiguity between them.
All tool names follow the same haul_verb_noun pattern using lowercase snake_case. This makes the API surface predictable and easy to navigate.
Five tools is well-scoped for a verification service with account management. Each tool serves a clear purpose and none feel redundant or missing.
The tool set covers the full user workflow: checking balance, verifying email or phone, adding credits via top-up, and discovering available tools. No critical gaps exist for the stated domain.
