Three drift vectors hit every deployed agent
Prompts rot as the model behind them changes. Models update on cycles set by the vendor, not by you. Data shifts as the business shifts. Each of these is a slow degradation that nobody notices until something downstream breaks.
Monitoring is non-negotiable
Production agents need monitoring on the dimensions that matter: cost, latency, success rate against an evaluation suite, and the user-facing outcomes the agent is supposed to deliver. Without that telemetry, the system runs blind.
Governance is part of operations
Access controls, audit logs, and the governance posture do not stay current on their own. Managed operations carries the governance work forward with the system.
