Chapter 22
22Agents
22.1What 'agent' actually means
Planned: A loop of plan-act-observe; autonomy as a spectrum, not a binary.
22.2Planning and memory
Planned: Decomposition, scratchpads, and external memory; ReAct-style loops.
22.3Multi-agent systems
Planned: Orchestrator/worker patterns; when more agents help and when they just add noise.
22.4Why agents are hard
Planned: Error compounding over long horizons; evaluation and cost.
