Scored across 8 tools
Each tool targets a distinct action: email lookup, email verification, domain email listing, person/company enrichment, people/company search, and combined reporting. No two tools overlap in purpose, and the descriptions clearly differentiate them.
Most tools follow a clear verb_noun pattern (find-email, verify-email, enrich-person, search-people, etc.), but 'domain-search' and 'lead-report' are noun-heavy deviations. The overall hyphenated lowercase style is consistent, so only minor inconsistency exists.
With 8 tools, the set is well-scoped for a lead generation/enrichment server. Each tool serves a clear function without redundancy, and the count falls comfortably within the ideal range.
The tools cover the full lead generation workflow: discovery (search-people, search-companies), email lookup (find-email, domain-search), verification (verify-email), enrichment (enrich-person, enrich-company), and synthesis (lead-report). No major gaps or dead ends are apparent.
