You'd reach for this when you need to run code quality checks and transformations without leaving your Claude conversation. It exposes Ruchy's toolkit for analyzing code structure, scoring quality metrics, running linters, applying formatters, and transpiling between languages or versions. Think of it as bringing your local development workflow into the chat: ask Claude to lint a Python file, score some JavaScript for maintainability, or transpile legacy code to modern syntax. The server handles the heavy lifting of running these tools and returns results you can act on immediately. Most useful when you're iterating on code snippets or reviewing files and want automated feedback without context switching to your terminal.
