Agent

An AI system that takes actions in the world toward a goal, typically in a loop and with some autonomy, rather than only producing an output and waiting. Because an agent acts (sends, moves, deletes, calls other systems) faster than a human can review each step, it is the class of system for which a scoped deployment, containment, and a tested kill switch are essential rather than optional.

A system that plans a multi-step approach toward a goal, chooses and calls tools, connects to other systems and agents through defined protocols, and executes real actions, not merely descriptions of actions. Defined by the framework through eight core components: model, instructions, memory, planning and reasoning, tools, protocols, controls, and logging and monitoring.

an AI system that can perceive, reason, and act toward a goal, distinguished from a chatbot by its ability to take actions, not just produce text. (see Topic 0.2)

An AI system that takes actions in the world (calls tools, changes records, moves money, sends messages) rather than only producing text for a human to act on. The action, not the intelligence, is what makes logging it a governance duty.
