Put Guardian in front of the agent you already have.

from nrtvix import GuardedToolbox

tools = GuardedToolbox(bridge)          # your workspace + agent identity

result = tools.call("refund_order", order="ORDER-1042", amount=180)

if result.status == "executed":
    ...                                 # done by the trusted gateway
elif result.status == "awaiting_approval":
    ...                                 # tell the customer it is with the owner
else:
    ...                                 # blocked or refused: do not retry
