Agents drift. Running them properly is a discipline, not an afterthought.
AgentOps is the operational discipline of running AI agents in production: tracing what they do, evaluating whether they are still doing it correctly, controlling cost, and reverting safely when they are not. Agents degrade for reasons that have nothing to do with the model being wrong. A supplier updates a model version. Someone edits a prompt. A tool schema changes. A source document is revised. Each is individually harmless and collectively capable of changing behaviour without anyone noticing, which is why most agent incidents in production trace back to tool-call failures, truncated context and runaway loops rather than to the model itself.
