@matiasperrone-exo this is unclean, either revert the entire PR so no documentation code is present, since only removing the culprit methods will leave swagger headless, or override them correctly so they get picked up:

use AddSummitChildElement {
    add as private traitAdd;
}

#[OA\Post(...)]
public function add($summit_id)
{
    return $this->traitAdd($summit_id);
}

I defer to @smarcet on which one fits best in this case.

@martinquiroga-exo please follow this pattern swagger framework pick up the documentation automatically

LGTM its follows the approved pattern
