    A4.3/5.0

    Scored across 9 tools

    Disambiguation5/5

    Each tool has a clearly distinct purpose: schema discovery, table listing, detailed table description, column search, relationship traversal, data preview, query execution, query planning, and documentation export. There is no practical overlap; even sample_rows and run_select differ in that one is a convenience for previewing a table and the other is for arbitrary read-only queries.

    Naming Consistency4/5

    Eight of nine tools follow a clear verb_noun snake_case pattern (list_schemas, describe_table, run_select, etc.), making the set predictable. The single exception is table_relationships, which uses a noun_noun form, creating a minor inconsistency without causing confusion.

    Tool Count5/5

    Nine tools is well-scoped for a PostgreSQL schema and querying server. Each tool fills a distinct role in the workflow from schema discovery to query tuning, and none feel redundant or bolted on.

    Completeness5/5

    The tool surface covers the full read-only lifecycle: schema/table discovery, column search, relationship mapping, data sampling, safe SELECT execution, query planning, and exporting a data dictionary. There are no obvious dead ends for an agent exploring or querying a database, and the explicit lack of write mode is a deliberate boundary rather than a gap.
