codanna vs ScalaSemantic

codanna: Codanna provides 'X-ray vision' for AI code assistants, enabling them to understand code structure, trace relationships, and find implementations with precision. It facilitates context-first coding, eliminating the need for manual searching and speeding up R&D and pair programming workflows.; ScalaSemantic: ScalaSemantic is an MCP server that provides AI coding agents with compiler-resolved Scala facts like symbols, types, and usages via SemanticDB. It allows agents to query precise compiler knowledge rather than relying on less accurate source text grepping, significantly reducing token usage.
