Respira’s ACF tools cover field reads and writes, field group management, repeater and flexible content operations, options pages, and relationship fields. Every write creates a snapshot and routes through your approval settings, so bulk ACF updates never corrupt a site. `wordpress_create_acf_field_group` Create an ACF (Advanced Custom Fields) field group. Requires ACF (free or Pro) active on the site — call wordpress\_get\_site\_context first to confirm. Stored in wp\_option respira\_custom\_acf\_field\_groups and registered via acf\_add\_local\_field\_group() on acf/init. Use to bind structured fields (text, number, image, post relation) to specific post types via the location rules.
