Agents에는 더 많은 프롬프트가 아니라 제어 흐름이 필요하다

Most AI agent development emphasizes prompt engineering, but production reliability requires deterministic control flow and programmatic scaffolding rather than relying solely on LLM capabilities. This challenges vendor marketing that promotes all-encompassing managed agents, revealing that the real bottleneck is system design, not model performance. Understanding this distinction is essential for teams building trustworthy agents that must perform consistently at scale.
