How many tools are needed for types & docs for Ruby on Rails?

I know it’s OK to code without types and docs, but if you want them (like Java, TypeScript, Python, etc.), below is the setup you may have to go through. I’m thinking about having a new project-create-toolkit to include all of them, otherwise it’s painful and waste of time to manually set up each of them for every new Ruby on Rails project.

Install and setup the gems:

Linter: 
gem 'rubocop', require: false
Static Type Checker: 
gem 'sorbet', :group => :development
gem 'sorbet-runtime'
gem 'tapioca', require: false, :group => :development
gem 'webrick'
Type Annotation: 
gem "rbs"
Annotate controllers with route info: 
gem "chusaku", require: false
Annotate models and routes 
gem 'annotate'

In lib/tasks, create `routes.rake`

task routes: :environment do
Rails.application.eager_load!
models = ApplicationRecord.descendants.collect(&:name).join('|').downcase
controllers = ApplicationController.descendants.collect(&:name)
controllers = (controllers.map { |controller| controller[0..-11].downcase }).join('|')
if models
puts `bundle exec rails routes -g "#{models}|#{controllers}"`
else
puts `bundle exec rails routes -g "#{controllers}"`
end
end

Install and setup VS Code Extensions:

Most importantly, Shopify’s Ruby extension set, but also add all those for ERBs, etc.
