The toolset establishes a clear primary entry point (lookup_dongguk_rule) and explicitly labels search_rule, search_rule_deep, get_rule_content, and get_rule_toc as auxiliary, so the intended hierarchy is mostly clear. However, multiple overlapping retrieval/search tools still create some risk of misselection for an agent that does not carefully follow the Korean-language guidance.

All names use snake_case and are mostly verb_noun (get_rule_toc, list_rule_history, search_rule_deep, verify_rule_citations). The adjective_noun 'applicable_rule' is a minor outlier, and auxiliary qualifiers like 'deep' and 'dongguk' are not fully systematic, but overall naming is predictable.

Ten tools is well within the appropriate range for a regulation-domain server, and each covers a distinct operation: primary lookup, candidate search, content/TOC retrieval, history, version comparison, date-applicable lookup, citation verification, and service info. No tool appears purely redundant at the count level.

Coverage is broad: search, retrieval, TOC, history, version diff, point-in-time lookup, citation verification, and service diagnostics are all present. A minor gap is the absence of a direct 'get full regulation by LAW_ID' tool without first querying or drilling into the TOC/article, though agents can work around it.
