uml-viewer scans a Ruby or Rails project with Prism and shows it as a UML diagram in the browser. Red arrows show dependencies that break the Dependency Rule between Rails layers. Box colors show CRAP from a SimpleCov run. A right-click sends a command to a Claude Code session, which explains the code, changes the policy or writes a proposal. Nothing is written into the viewed project. Based on the ideas of unclebob/uml-viewer by Robert C. Martin (Uncle Bob), a Clojure tool. No code is copied.
