Scored across 6 tools
Each tool has a clearly distinct purpose with no ambiguity: get_gem_owners retrieves owners of a gem, get_gem_reverse_dependencies finds dependent gems, get_gem_versions lists versions, get_owner_gems shows gems owned by a user/org, get_rubygem_info provides general gem information, and search_rubygems searches for gems. The descriptions clearly differentiate their functions, making misselection unlikely.
All tools follow a consistent verb_noun pattern with 'get_' or 'search_' prefixes followed by descriptive nouns (e.g., get_gem_owners, search_rubygems). The naming is uniform throughout, using snake_case consistently without any deviations or mixed conventions.
With 6 tools, the count is well-scoped for a RubyGems server, covering key operations like searching, retrieving info, versions, dependencies, and ownership. Each tool earns its place without feeling excessive or insufficient for the domain's typical needs.
The tool set provides comprehensive read-only coverage for querying RubyGems, including search, info retrieval, version history, dependencies, and ownership. A minor gap exists in write operations (e.g., publishing or managing gems), but this is reasonable for a query-focused server, and agents can work around this limitation.
