Each tool targets a clearly distinct concern: run_sql executes queries, get_schema returns metadata, search_briefs finds briefs semantically, get_brief retrieves one brief by pcode, and glossary_lookup defines terms. There is no meaningful overlap between these operations.

Four tools follow a verb_noun pattern: run_sql, get_schema, search_briefs, get_brief. glossary_lookup is the outlier, since it reads as noun_verb rather than lookup_glossary, but the naming is otherwise consistent and all use snake_case.

Five tools is a well-scoped size for a domain combining queryable atlas views, brief retrieval/search, and glossary references. Each tool provides a distinct capability without redundancy or unnecessary surface area.

The core workflows are covered: schema discovery, data querying, brief search, brief retrieval, and term definition. A minor gap is that there is no direct way to enumerate all pcode values or list all briefs, though search_briefs and get_schema can help agents work around this.
