Agent mode

The operating mode in which an AI system uses tools, carries state across multiple steps, and acts on external systems with limited per-action human supervision. Most enterprise software vendors use 'agent mode' to label features where their AI both proposes and executes — distinguishing it from suggest-only assistant features.

Agent mode is configuration-dependent, not vendor-fixed. The same product is often both: Claude with computer-use is in agent mode; Claude in plain chat is not. Microsoft 365 Copilot in suggest-mode is an assistant; Copilot Agent Mode is an agent. Procurement teams that buy a product without specifying which mode it ships in inherit governance liability they didn't budget for.
