Scored across 6 tools
Each tool has a distinct role in the pipeline: search discovers resources, resolve retrieves full metadata, fetch downloads files, operate inspects remote tabular data, relate suggests joins, and list_sources describes capabilities. There is no meaningful overlap between the tools.
Five tools use a consistent single-verb imperative style (search, resolve, fetch, operate, relate), and list_sources follows the common verb_noun pattern. The only minor inconsistency is that list_sources is compound while the others are single words, but the overall style is clear and predictable.
Six tools is well-scoped for a data aggregation server: discovery, resolution, download, source inspection, remote query, and relation hinting are each represented without redundancy. The count feels neither thin nor bloated.
The tool set covers the full aggregation workflow from querying many sources to resolving records, downloading files, inspecting remote tabular data, and understanding dataset relationships. Missing mutation operations are appropriate because this is a read-oriented aggregator, not a repository management system.
