Each tool targets a distinct data access pattern: schema, provenance, exact row lookup, fuzzy search, comparisons, top/bottom rows, and numeric stats. There is mild overlap between dataset_row and dataset_compare since both filter by column values, but their intended use cases are clearly differentiated.

All tools share a consistent dataset_ prefix and use snake_case, which makes the set look cohesive. However, the suffixes mix nouns (columns, row, stats, top, provenance) with verbs (compare, search), so the pattern is not perfectly uniform.

Seven tools is a well-scoped size for a single-dataset query server. Each tool covers a meaningful access mode without unnecessary redundancy or overwhelming the agent.

The tool set covers the core data exploration lifecycle: schema discovery, metadata, exact lookup, search, comparison, top/bottom ranking, and summary statistics. It lacks arbitrary multi-condition filtering or grouped aggregations, but those are not clearly required for the stated dataset Q&A purpose.
