TDQS

B3.1/5.0

Scored 2026-06-14 23:35 across 3 tools

Disambiguation5/5

Each tool has a distinct purpose: ingesting documents, querying a table, and retrieving table details. No overlap exists.

Naming Consistency5/5

All tool names follow a consistent verb_noun pattern (ingest_docs, query_table, table_details) using snake_case.

Tool Count4/5

Three tools is minimal but appropriate for a basic LanceDB server covering ingestion, querying, and metadata inspection. Slightly limited but not unreasonable.

Completeness3/5

Covers core operations (ingest, query, details) but lacks delete, update, or list tables, which are notable gaps for a database server.
