Definition
The how-to-build guide contrasts three architectures: traditional software, LLM agents that choose their own next step, and AI-powered software where code handles deterministic work and keeps control flow. In the third, each AI task is atomic and constrained.
The summary is blunt: build a normal software workflow and insert System One only where AI is needed. Control flow, rules, and side effects stay in code; the model handles narrow judgments over unstructured input.
