Scored across 9 tools
The two index advisors are cleanly separated by input source (user-supplied SELECTs vs. pg_stat_statements workload), and read paths (list_schemas, list_objects, get_object_details) are distinct. Minor overlap exists between explain_query and execute_sql's EXPLAIN mode, and between get_top_queries and diagnose's slow-query/log checks, but descriptions make the intended split clear.
Nearly all tools follow a predictable snake_case verb_noun pattern (list_schemas, list_objects, get_top_queries, analyze_workload_indexes). The lone bare verb 'diagnose' is the only deviation, though it is still readable and distinct.
Nine tools is well-scoped for a read-only Postgres diagnostics/monitoring server, with no redundant entries and each tool earning its place. Nothing feels padded or missing at the count level.
The surface covers discovery, inspection, ad-hoc querying, plan explanation, index advising, and health checks — a solid lifecycle for a diagnostic (non-mutating) server. Gaps are minor: no direct access to server settings/pg_settings or explicit index list, though get_object_details and diagnose cover much of that indirectly.
