Why "Build an AI Agent" Is the Wrong Starting Point for AI Systems

The industry is obsessed with agents and prompting. That focus is not wrong—but it is incomplete. Real production systems require architecture, determinism, integration, and human interaction.

It is whether it can generate systems—coherent, deployable, and reliable. That requires design, not just generation.
