Building Reliable AI Agents Demands Engineering Discipline, Not Vibes

The post argues that working with AI agents requires systematic engineering practices—prompt engineering as a discipline with measurable constraints, not trial-and-error tinkering. This reflects a real split in developer communities between those shipping production systems (who care about reproducibility, versioning, testing) and those experimenting with demos (who celebrate "surprising" emergent behaviors). The distinction matters because it determines whether AI tooling becomes commodified infrastructure or remains artisanal craft.
