Scored across 7 tools
Each tool targets a distinct operation: fetching class content, finding definitions, document outline, hover info, implementations, references, and workspace symbol search. No overlap in purposes.
All tools follow a consistent 'java_<noun>' pattern with snake_case naming. The prefix and noun structure is uniform across the set.
7 tools is an appropriate number for a code navigation server. It covers essential browsing operations without being excessive or insufficient.
The tool set covers core code exploration: definition, references, implementations, hover, document outline, and symbol search. Missing features like code completion or diagnostics, but the set is reasonable for static analysis.
