1. A method comprising:
forming a wellbore assembly by:
installing a second wellbore tubular within a hollow volume defined by a first wellbore tubular, wherein the second wellbore tubular installed within the hollow volume defines a tubing-to-tubing annulus (TTA) between an outer wall of the second wellbore tubular and an inner wall of the first wellbore tubular,
attaching a first connection at a first end of the wellbore assembly, the first connection attached to the first wellbore tubular and the second wellbore tubular, the first connection coupling the first end of the wellbore assembly to a wellbore tool, and
attaching a second connection at a second end of the wellbore assembly opposite the first end of the wellbore assembly, the second connection attached to the first wellbore tubular and the second wellbore tubular, the second connection coupling the second end of the wellbore assembly to a wellbore tool;

installing the wellbore assembly within a wellbore;
while performing wellbore operations within the wellbore, periodically measuring a pressure within the TTA; and
based on a result of periodically measuring the pressure within the TTA, determining a leak in the second wellbore tubular.
