## What it is
ActiveDecorator is a Ruby gem that provides ORM-agnostic, object-oriented view helpers for Rails applications. It automatically mixes decorator modules into model objects only within the view context, keeping views and helpers clean and object-oriented.

## Use cases
- decorate Rails models for view rendering
- keep view logic object-oriented instead of procedural helpers
- format model attributes in views without cluttering helpers
- auto-decorate model collections and associations in partials
- call ActionView helpers like link_to from decorator modules

## When to choose
- you use Rails 4 through 8 and want lightweight, implicit decorators
- you prefer decorator modules over presenter objects with explicit wrapping
- you want decorators that can call ActionView helper methods directly
- you use ActiveRecord, ActiveResource, or any plain Ruby object ORM

## When to avoid
- you use Sinatra, Hanami, or non-Rails frameworks
- you need standalone presenter objects usable outside the view context
- you prefer explicit decoration like Draper's `decorates` style

- artifact type: library
