Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Flog-Driven Development
You point flog to a file, or directory, and it provides you with a score. The higher the score, the more attention you might want to pay to it. As for how flog calculates the number, I'll let flog summarize itself again:
-
Improve Code in Your Ruby Application with RubyCritic
Flog checks how difficult your code is to test. It sets a complexity score for each line of code and sums up the score for each method and class.
-
Gems that can identify churn, complexity, duplication and smells.

First commits in a Ruby on Rails app
Rubycritic uses reek under the hood so I added a reek config files at .reek.yml with the following content:
-
Code Reviewing a Ruby on Rails application.
Reek is a code smell detection tool for Ruby that helps identify potential design issues. It analyzes your codebase and provides feedback on areas that might benefit from refactoring or improvement. Here's an overview of what Reek is and how to use it:
-
Improve Code in Your Ruby Application with RubyCritic
$ reek app/controllers/erp/orders_controller.rb Inspecting 1 file(s): S app/controllers/erp/orders_controller.rb -- 1 warning: [91]:UncommunicativeVariableName: Erp::OrdersController#create has the variable name 'e' [https://github.com/troessner/reek/blob/v6.1.1/docs/Uncommunicative-Variable-Name.md]

The best way to review my code for code smells?
Beside RuboCop, I found reek very useful. https://github.com/troessner/reek
