An AI agent that has been hijacked still looks busy. It keeps
answering, keeps closing tasks — it just does it for a different goal. Counting its activity won't
catch that. So we measure something else: the shape of its behaviour over time.
1We learn what normal looks like
From your agent's own healthy history we compute its typical mix of behaviours. That mix is the
reference — measured, never decided by hand.
2We watch the mix move
Every few minutes we compare what the agent is doing now against that reference. A small gap is
normal. A gap that grows and stays is an agent drifting off its job.
3We can stop it
Past a threshold the conversation is held: the agent stops being allowed to act on its own
and a human is asked. Nothing is deleted, everything is logged.
The one number to know: DRIFT. 0 means the agent is behaving exactly like
its healthy self. Above 0.25 it is wandering. Above 0.35 it is treated as off-mission.
Everything else on this page is detail behind that one number.
