Scored across 3 tools
Each tool has a distinct purpose: listing supported TLDs, refreshing the server list, and performing WHOIS lookups. There is no functional overlap, so agents can easily select the correct tool.
All tool names use snake_case with a verb-noun structure (list_supported_tlds, refresh_whois_servers). whois_lookup deviates slightly by placing the verb at the end, but the pattern is still clear and consistent overall.
Three tools is well-scoped for a WHOIS lookup service. Each tool serves an essential function with no redundancy or bloat, striking an appropriate balance for the domain.
The tool set covers all necessary operations: querying supported TLDs, updating the server list, and performing lookups. No obvious gaps exist for the core functionality of a WHOIS lookup service.
