WP_CLI::add_wp_hook() Edit

Add a callback to a WordPress action or filterFilter Filters are one of the two types of Hooks https://codex.wordpress.org/Plugin_API/Hooks. They provide a way for functions to modify data of other functions. They are the counterpart to Actions. Unlike Actions, filters are meant to work in an isolated manner, and should never have side effects such as affecting global variables and output..

add_action() without needing access to add_action(). If WordPress is
already loaded though, you should use add_action() (and add_filter())
