Duplicate content
The Duplicate content ECA workflow adds a "Duplicate" action to content items and pre-fills the add form with a copy of the original, so an editor can create a new item based on an existing one.
This model is provided by the Drupal CMS Content Type Base recipe (drupal_cms_content_type_base). The screenshot below shows the model open in the Workflow Modeler.

How It Works
The model uses three events to add the "Duplicate" entry point and then to copy the original content:
Event, Operation links: Adds a Duplicate link to each content item's list of operations. The link points to the "add content" form for the same type, with a duplicate query argument carrying the original item's ID.
Event, Alter local task: Adds the same Duplicate entry as a tab on the content item.
Event, Prepare entity form: When the add form opens with a duplicate argument, the workflow loads the original item, shows a message ("You are duplicating …"), and clones the original's field values into the new item so the form is pre-filled. The new item starts unpublished.
A create access? condition first checks that the current user is allowed to create that content type, so the Duplicate action only appears for users who can use it.
Viewing the Model
Go to Administration \ Configuration \ Workflow \ ECA, find Duplicate content, and open it in the Workflow Modeler to see how the events, condition, and clone actions connect.
