AI-based oversight systems monitor autonomous agents in production to ensure reliable, compliant operation. They track decision traces, maintain immutable logs, evaluate performance metrics, detect anomalies, and enforce policy constraints in real time, issuing alerts and enabling rapid rollbacks. Governance frameworks combine rule-based checks and model-based auditors to assess agent actions against safety and compliance standards. Continuous auditing, version control, access management, and explainability tools support accountability, reduce drift, and help teams scale agent deployments responsibly.
