A Ruby Interface file generator for gems, core types and the Ruby standard library

A static architecture linter for Ruby and Rails. Declare your components, dependencies, and boundaries in one file, then check every change in CI. It indexes source with Rubydex and never boots the app.

Auditions scripts, gems, Rack apps, and Rails applications for the ability to run under Ractors: static analysis of Ractor-isolation violations plus dynamic in-Ractor probing, with explanations and fixes.

A set of rubocop settings used in my own projects.Support for: vanilla ruby, rspec, rails.

Catenary generates selective, translation-validated lowered Ruby for Rails 8.1+ applications running on Ruby 4.0+.

Static and observational runtime fiber-scheduler auditor for Ruby and Rails

Moult sheds dead code. `moult hotspots` ranks files by a complexity x churn score (Prism-parsed ABC complexity per method x per-file git churn); `moult deadcode` lists confidence-graded unused-method and unused-constant candidates over a rubydex definition graph, with Rails entrypoint awareness. Every finding carries a confidence and its reasons, never a claim of certain death.

Maps a Rails app so assistants stop guessing — static context files and a read-only MCP server.

Ripple Effect maps the blast radius of Ruby on Rails changes. It combines Ruby-aware static indexing with Rails semantics (callbacks, associations, routes, jobs, mailers, concerns, and test references) to explain what may be affected before you refactor. It is deterministic and local: it does not boot your application, connect to your database, call an LLM, or upload your source code.

RuboCop cops and shared configuration for the Callback Systems Ruby style in Rails applications and Ruby gems.

A RuboCop extension that enforces ViewComponent best practices and conventions

RubyLens uses Rubydex to map Ruby code and generate private, local-first data for local interactive reports and cinematic visual showcases.
