This wraps rust-analyzer's LSP capabilities into Claude, so you can ask "where is Config defined?" or "who uses this function?" in plain English instead of clicking around your editor. It handles go to definition, find references, hover info, and workspace symbol search. The multilingual trigger support is a nice touch if you're working with international teams. The output formatting looks clean with code snippets and reference tables. Honestly most useful when you're exploring an unfamiliar codebase or doing pre-refactoring impact analysis. Just make sure rust-analyzer is actually running or you'll get nothing back.
