/new-feature — Scaffold CQRS Class + Spec

Create a new command, query, or service class following the project's CQRS conventions.

Usage

• /new-feature command LogSomething — create a command
• /new-feature query SomeStats — create a query
• /new-feature service SomeCalculator — create a service

If no arguments provided, ask the user: "What type (command/query/service) and what name?"

Scaffolding Rules

1. Determine the Layer

2. Create the Class File

File name: lib/rails_error_dashboard/<type>s/<snake_case_name>.rb

Follow this pattern (read an existing file from the same directory for reference):

• Module: RailsErrorDashboard::<Type>s::<ClassName>
• Factory method: def self.call(...)
• Constructor: def initialize(...)
• Instance method: def call
• Commands: rescue errors, never raise in capture path
• Queries: return data, never mutate
• Services: pure computation, no DB access

3. Create the Spec File

Spec path: spec/<type>s/rails_error_dashboard/<snake_case_name>_spec.rb

Follow this pattern (read an existing spec from the same directory for reference):

• RSpec.describe RailsErrorDashboard::<Type>s::<ClassName> do
• Test self.call factory method
• Test main behavior
• Test edge cases (nil input, empty data, errors)
• Commands: test that errors are rescued (never raise)
• Queries: test filters, sorting, empty results
• Services: test computation accuracy, edge cases

4. Register if Needed

• If the class needs to be autoloaded, check if lib/rails_error_dashboard.rb needs an autoload entry
• If the class adds a dashboard feature, check if config/routes.rb needs a route
• If the class adds a config option, add it to lib/rails_error_dashboard/configuration.rb

Before Creating

Always read at least one existing file from the target directory to match:

• Exact module nesting
• Code style (rails-omakase, array brackets with inner spaces)
• Error handling patterns
• ActiveSupport::Notifications instrumentation (commands)

After Creating

1. Run the new spec to verify it passes:

   bundle exec rspec spec/<type>s/rails_error_dashboard/<snake_case_name>_spec.rb

2. Run RuboCop on the new files:

   bundle exec rubocop lib/rails_error_dashboard/<type>s/<snake_case_name>.rb spec/<type>s/rails_error_dashboard/<snake_case_name>_spec.rb
