Drift alerts notify you when Nomotic detects a statistically significant shift in an agent’s behavior. Catching drift early — before it becomes a problem — is one of the core reasons to use behavioral governance rather than static access control.
What Nomotic monitors for drift
Agent behavioral drift — changes in action types, targets, timing, verdict rates, or UCS scores that diverge from the agent’s established baseline.
Human drift — a pattern where your team’s reviewers become less effective over time in the escalation workflow. Rising approval rates, falling reversal rates, and long streaks of consecutive approvals without challenge are all signals of human drift.
Types of drift alerts
Verdict drift — the agent’s ALLOW rate changed more than 20% week over week. Could indicate a policy change that is too loose or too tight, or genuine behavioral change in the agent.
UCS decline — the agent’s average confidence score has trended down for more than 7 days. Often indicates the agent is taking on new action types it isn’t well calibrated for.
Trust erosion — the agent’s trust score has declined more than 0.1 over the analysis period.
Escalation surge — the rate of escalations from this agent has increased significantly.
Where alerts appear
Drift alerts appear in the Alerts section of the main navigation. Each alert shows the affected agent, the type of drift, the severity, and when it was first detected. You can acknowledge an alert (marking it as seen) or resolve it (marking it as addressed).
Responding to a drift alert
The right response depends on the type of drift. For verdict drift or UCS decline, start by reviewing recent evaluations in the audit trail to understand what changed. For trust erosion, look at whether the agent’s action mix has shifted or whether a recent deployment changed its behavior. For escalation surge, check whether new action types are being introduced that need policy tuning.
Drift alerts are available on Team and above plans.
