TDQS

A3.7/5.0

Scored across 7 tools

Disambiguation4/5

Each tool targets a distinct query mode—schema, provenance, exact lookup, substring search, multi-value comparison, statistics, and top/bottom ranking. dataset_row and dataset_compare are arguably similar, but the compare tool is clearly scoped to ordered multi-value comparisons, so the overlap is manageable.

Naming Consistency4/5

All tools share a consistent dataset_ prefix and snake_case naming, which makes them highly predictable. The suffixes mix nouns (columns, stats) and verbs (search, compare), so it is not a strict verb_noun pattern, but the convention is still coherent.

Tool Count5/5

Seven tools is well-scoped for a dataset querying server. Each tool covers a distinct data exploration need without redundancy, and the count is comfortably within the ideal range.

Completeness5/5

The server covers schema discovery, provenance attribution, exact and fuzzy row retrieval, comparison queries, numeric aggregations, and ranking. For a read-only single-dataset server, there are no obvious gaps that would block normal usage.

Available Tools

7 tools
dataset_columnsDataset columns and shapeAInspect

The columns, which of them are numeric, the row count and the provenance banner of the Proofzo dataset. Call this first to learn the schema.

Inputs: no named parameters.

dataset_compareCompare rows side by sideAInspect

The rows of the Proofzo dataset whose column is any of the given values, in the order given — for "X vs Y" questions.

Inputs: column (required), values (required).

dataset_provenanceWhere this data comes from, and how to cite itAInspect

The source, the date it was computed, the licence and the citation for the Proofzo dataset. Read this to attribute a figure correctly.

Inputs: no named parameters.

dataset_rowLook a row up by an exact keyCInspect

The rows of the Proofzo dataset where a column equals a value exactly (case-insensitive).

Inputs: value (required), column (required).

dataset_statsSummary statistics for a numeric columnAInspect

count, min, max, mean, median and sum of a numeric column of the Proofzo dataset (grouping commas and currency are handled; non-numeric rows are excluded and counted).

Inputs: column (required).

dataset_topRank rows by a numeric columnCInspect

The highest (or lowest) rows of the Proofzo dataset by a numeric column — "which is the most/least X".

Inputs: column (required), limit, ascending.
