    A4.5/5.0

    Scored across 11 tools

    Disambiguation4/5

    Tools are largely distinct by resource and action: search, get, cite, resolve, references, author/journal/funder lookup, snowballing, and related works. Some overlap exists between find_related_works and snowball_doi's related component, and between get_crossref_references and snowball_doi's backward citations, but descriptions clearly distinguish Crossref text similarity from OpenAlex citation graph.

    Naming Consistency4/5

    All names use snake_case and follow a mostly verb_noun pattern. However, the use of 'crossref' is inconsistent: get_crossref_* is prefixed, search_crossref is suffixed, and cite_dois/resolve_dois/snowball_doi/find_related_works omit it entirely. Still readable and predictable overall.

    Tool Count5/5

    11 tools is well-scoped for a Crossref metadata server. Each tool earns its place by covering a distinct part of literature discovery, metadata retrieval, citation formatting, or entity profiling.

    Completeness5/5

    The surface covers search, topic analysis, work metadata, citation formatting, DOI resolution, reference lists, citation snowballing, and author/journal/funder profiles. There are no obvious gaps for the stated domain of scholarly metadata discovery and analysis.
