This Skill helps you extract view-specific logic from your Rails models into dedicated presenter objects, leading to cleaner, more maintainable code and simpler views.
User model with methods like display_name and status_badge_class that are only used in the UI. This Skill will help you move that logic into a UserPresenter.Use the presenter-agent skill to create a presenter for the Product model that formats the price as currency and provides a status_label method.

To extract view-specific logic from Rails models into presenters, you generate Ruby presenter objects using SimpleDelegator. This moves presentation methods into dedicated classes, cleanly separating display concerns from core model logic.
The best way to clean up formatting methods in Ruby on Rails views is moving that logic into dedicated presenter classes. Encapsulating view-specific formatting like currency display or status labels in presenters keeps your views concise and maintainable.
SimpleDelegator works for creating Rails view models by delegating undefined method calls back to the wrapped model object. This allows presenters to inherit model behavior while adding presentation-specific formatting and display logic.
RSpec tests are written alongside each Rails presenter generated with SimpleDelegator. You need RSpec to verify that the encapsulated view-specific formatting and display logic behaves correctly within the dedicated presenter classes.
Yes, you can move conditional display logic like status badge classes out of your Rails models. By creating a dedicated presenter object, you encapsulate UI-specific presentation code, ensuring models remain strictly for domain logic.
