    A4/5.0

    Scored across 5 tools

    Disambiguation5/5

    Each tool targets a distinct resource and action: search vs. retrieve for both main entities and sub-units, and roles retrieval for a specific entity. There is no overlap or ambiguity among the five tools.

    Naming Consistency5/5

    All tool names follow the same Norwegian verb_noun pattern: 'sok_' for searching and 'hent_' for retrieving, with the entity type appended. This creates a predictable and coherent naming convention across the entire set.

    Tool Count5/5

    Five tools is a well-scoped count for a business registry lookup server, covering the two core entity types (foretak and underenheter) with both search and detail retrieval, plus a roles endpoint. It feels complete without being bloated.

    Completeness4/5

    The tool set covers the essential read-only operations for the domain: searching and retrieving main entities and sub-units, and fetching roles. A minor gap is the lack of a direct endpoint to list all sub-units for a given parent company, but this can be worked around via the search tool by filtering on the parent's organization number.
