A4.4/5.0
Scored across 4 tools
Disambiguation5/5
Each tool has a clearly distinct role: general offline Q&A, single-page source-bounded analysis, static preview of paid verification, and evidence-backed condition testing. The descriptions explicitly cross-reference when to use the alternatives, reducing misselection.
Naming Consistency3/5
All names use snake_case, but the set mixes Portuguese verb phrases (analisar_url, consultar_ia, verificar_condicoes) with an English noun phrase (preview_verification). The convention is readable but not fully consistent.
Tool Count5/5
Four tools is well-scoped for a focused web-verification service. Each tool covers a distinct workflow stage without redundant endpoints.
Completeness4/5
The surface covers the core lifecycle: free preview, general Q&A, page analysis, and paid condition verification with audit fields. Minor gaps include no multi-page or batch verification, but the stated single-page domain is well covered.
