The tools mostly target distinct resources and actions: source search vs. source retrieval, statute finding vs. article retrieval vs. outline/history/annex, citation auditing vs. precedent tracing, and contract risk scanning. The main mild overlap is that research_run and toolbox act as orchestration/catalog layers that conceptually touch specialized tools, but their descriptions still make roles clear.

All names use lowercase snake_case, and most follow a readable noun_verb pattern such as source_search, statute_find, article_get, annex_get, source_get, citation_audit, and precedent_trace. Exceptions such as statute_history, statute_outline, contract_risk_scan, and toolbox are still clear, so this is a minor deviation rather than inconsistency.

Twelve tools is well within the ideal 3-15 range for a legal research server and each tool covers a distinct facet: search, retrieval, statute structure, amendment history, annexes, citation audit, precedent tracing, contract scanning, and orchestration. No tool appears redundant or excessive for the stated scope.

The surface broadly covers the legal research lifecycle: statute discovery, article retrieval, annexes, amendment history, source search/retrieval, citation auditing, precedent tracing, contract risk scanning, and auxiliary features via toolbox. Minor gaps such as direct legal-term definitions or amendment alerts are relegated to toolbox rather than first-class tools, but core workflows have no dead ends.
