Prompt Engineering is a Legacy Skill

Context over Tricks

In 2024, we spent hours optimizing "system prompts" and finding magic phrases like "take a deep breath" to get better results. In 2026, with models like GPT-5.2 and Claude 5, the model understands intent instantly. The era of "Prompt Engineering" as a pseudo-mystical art is over.

The New Skill: Data Curation

Instead of prompt engineering, successful developers focus on context curation—feeding the model the right documents and examples to ground its reasoning. Garbage in, garbage out still applies, but now it's about the data, not the prompt syntax.

RAG (Retrieval Augmented Generation) pipelines are the new prompt engineering. How do you chunk your data? How do you rank it? How do you present it to the model? These are the high-leverage questions today.

Evaluation Driven Development (EDD)

The other side of the coin is evaluation. You don't improve prompts by guessing; you improve them by running benchmarks. Tools that allow you to systematically test your prompts against 100 test cases are the IDEs of the prompt era.
