Scored across 7 tools
fetch and get_place both return published figures for a single UK area, differing mostly in input (page path vs area) and detail level, so agents could easily misselect. search vs search_places and search_places vs lookup_postcode also overlap on name/postcode lookups, though descriptions do provide some separation.
Most names follow a verb_noun snake_case pattern (compare_places, get_place, get_ranking, lookup_postcode), with only bare verbs fetch and search deviating. The convention is otherwise predictable and readable.
Seven tools is well-scoped for a UK area-statistics retrieval service, with each tool covering a distinct lookup facet (place, postcode, comparison, ranking, search). No redundant or trivial entries.
The surface covers name lookup, postcode lookup, single-area retrieval, comparison, and cross-area ranking, which is solid lifecycle coverage for read-oriented data access. Minor gaps exist, such as no explicit tool to list available measures/topics or retrieve multi-period time series.
