    Naming Consistency5/5

    All tool names follow a consistent verb_noun pattern with 'get_' or 'search_' prefixes, such as get_api_reference, get_backstage_examples, and search_backstage_knowledge. This predictable naming scheme enhances readability and usability.

    Tool Count5/5

    With 7 tools, the server is well-scoped for its purpose of providing Backstage knowledge and development resources. Each tool earns its place by covering distinct aspects like documentation, examples, guides, and search, without being overly sparse or bloated.
