Scored across 2 tools
Each tool has a clearly distinct purpose: one discovers an email address from a name and domain, the other checks if an existing email is deliverable. No overlap or confusion.
Both tools follow a consistent verb_noun pattern: find_email_by_name and verify_email. The naming is predictable and readable.
Only two tools, which is slightly below the typical 3-15 range, but they cover the core functions of an email lookup/verification service and each tool is essential.
The stated domain is email discovery and validation, and the two tools provide a complete workflow: find an email, then verify it. No obvious gaps for the intended use case.
