Scored across 6 tools
Each tool occupies a distinct phase of the data lifecycle: list_sources (source metadata), search (fan-out discovery), resolve (full record), operate (remote tabular inspection), fetch (download), and relate (join hints). The descriptions explicitly state boundaries (e.g. resolve returns the full record, fetch returns paths, relate is HINTS ONLY), so an agent can pick the right tool without confusion.
All names are lowercase snake_case and verb-oriented (search, resolve, fetch, operate, relate), giving a predictable pattern. The only minor deviation is list_sources, a two-word verb_noun form among single verbs, but it remains readable and consistent in style.
Six tools is well-scoped for a multi-repo data aggregation server; each tool maps to a necessary capability (source listing, search, resolve, fetch, inspect, relate) with no redundant or filler entries. Nothing feels thin or bloated.
The surface covers the full workflow from source awareness (list_sources) through discovery (search), record retrieval (resolve), file download (fetch), remote inspection (operate), and cross-dataset linkage (relate). No obvious dead ends for the stated aggregation purpose; relate being hints-only is an explicit design choice rather than a gap.
