Enable Ruby LSP in Claude Code — Quick Setup Guide

Ruby LSP is a language server for Ruby built by Shopify. It provides go-to-definition, document symbols, hover information, and diagnostics. In your editor - VS Code, Neovim, Zed - you probably already use it and do not even notice because it just works. In Claude Code, having LSP support means Claude can ask for things like: List classes/methods/constants in a file Jump to where a symbol is defined Find all usages of a symbol Get type info/docs for a symbol Search symbols across the whole project Find implementations of an interface Trace call hierarchy.
