WHAT IT DOES

What zernio_remove_contact_tag does on Zernio

AI agents use zernio_remove_contact_tag to create or update resources in Zernio, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Zernio environment.

RISK

Why zernio_remove_contact_tag is rated Medium

Removing a tag from a contact modifies the contact's metadata. While this is a modification (Write), it is potentially reversible since the tag could be re-added. It does not delete the contact itself or the tag definition, just the association. Severity is medium because misuse could alter contact categorization/segmentation at scale in a CRM context.
