Argues Tool Engineering Will Replace Prompt Engineering as AI Skill of Choice

A developer writer contends that prompt engineering, once a prized skill, is becoming obsolete as language models grow more capable. He points to three drivers: models now grasp plain-language requests without elaborate scaffolding, very large context windows reduce the need for compression tricks, and fine-tuning and retrieval-augmented generation solve problems that prompt hacks once addressed. He proposes a successor discipline, Tool Engineering, centered on building, selecting, and orchestrating the tools AI agents use to act in the real world. The piece argues that a model without tools can reason but cannot take actions such as booking a hotel or running a database query. Developers who keep investing in prompt techniques, he warns, risk becoming increasingly irrelevant.
