TDQS
Scored across 8 tools
Each tool targets a distinct aspect of code analysis: definitions, references, callers, impact, module overview, and Rails-specific associations/routes. No overlap in purpose.
All tool names follow a consistent snake_case pattern with a clear verb_noun or noun_of structure, making them predictable.
8 tools is well-scoped for a code analysis server, covering both general and Rails-specific functionality without bloat.
The set covers key analysis operations (definitions, references, callers, impact, module overview, routes, associations). A minor gap is the lack of a tool to list all modules without a specific path.
