Users define their editorial rules in YAML (see Settings -> Secretary) according to a number of built-in rule functions. For example, Secretary can show a warning if you’ve forgotten to set a Featured Image for your post, by adding the <code>featured-image</code> rule to your YAML config.
Secretary comes with a number of rules out of the box, but you can write your own custom plugins for Secretary by calling <code>SecretaryRules::register</code>. See example at https://github.com/ChrisBAshton/secretary-rule-gallery-at-top, and API documentation at https://github.com/ChrisBAshton/secretary.
