Scored across 4 tools
Each tool has a distinct retrieval shape: query-based search, key-based clause read, document listing, and document outline read. The only near-pair is get_clause vs. get_document, but the descriptions explicitly disambiguate by stating one returns words and the other returns structure without text.
All four tools follow a clean verb_noun snake_case pattern (search_policies, get_clause, list_documents, get_document). The verbs match the operation type precisely, with no mixed conventions.
Four tools is well within a sensible range and each maps to a necessary step in a read-only legal-lookup workflow: discover documents, browse outline, search, and read a clause. Nothing feels padded or missing for the scope.
The read-only surface covers the core loop of search → locate → read clause, plus document/version discovery. Minor gaps remain: no way to request a specific historical version of a clause, and get_document only exposes top-level structure, forcing extra get_clause calls for deep article traversal.
