A4.1/5.0
Scored across 7 tools
Disambiguation5/5
Each tool occupies a distinct niche: search returns snippets, where_does_term_appear gives only hit counts, lookup_citation retrieves full text, browse_structure shows hierarchy, what_changed lists dates, compare_versions shows diffs, and list_agencies maps agencies to titles. The descriptions explicitly cross-reference each other to guide the correct choice.
Naming Consistency4/5
Most tools follow a clear verb_noun pattern (lookup_citation, search_regulations, browse_structure, compare_versions, list_agencies), but two tools use interrogative phrases (where_does_term_appear, what_changed). This is a minor deviation that remains readable and predictable, but it is not perfectly uniform.
Tool Count5/5
Seven tools is well within the ideal range for a focused legal-research server. Each tool serves a distinct and necessary function for navigating, searching, and analyzing the CFR without redundancy or bloat.
Completeness5/5
The tool set covers the full research workflow: orientation (list_agencies, where_does_term_appear), discovery (search_regulations, browse_structure), retrieval (lookup_citation), and historical analysis (what_changed, compare_versions). There are no obvious dead ends; each tool refers to others for follow-up, creating a coherent end-to-end experience.
