Scored across 7 tools
Each tool has a reasonably distinct role: search_docs finds, get_docs retrieves, compare_versions diffs symbols, and lookup_package_docs queries PyPI metadata rather than docs. The main overlap is that whatsnew_for_version partly duplicates get_docs(slug='whatsnew/X.Y'), which the description itself acknowledges, but the ordered browsing and kind filtering give it a separate niche.
All seven tools use snake_case and a verb_noun or verb_object pattern (get_docs, list_versions, search_docs, compare_versions, detect_python_version, lookup_package_docs). The only off-pattern name is whatsnew_for_version, where the leading token is not a verb, but it remains readable and predictable.
Seven tools is well within the ideal 3-15 range for a documentation server. Each tool maps to a distinct capability (retrieval, search, versioning, detection, package metadata, changelog browsing) and none feel redundant.
The surface covers discovery (list_versions, detect_python_version), search, retrieval, cross-version diffing, changelog browsing, and third-party package URLs. Minor gaps exist, such as listing all symbols in a module or enumerating searchable kinds/scopes without trial, but core agent workflows are fully supported.
