It is interface design for language models. Treating prompts as products changes how teams build them.
Engineering implies a fixed spec and a right answer. Prompts are closer to interface design: you are shaping how a system behaves for real people with messy inputs.
That reframing pays off. Products get versioned, tested, reviewed, and owned. Treat prompts the same way and the magic-incantation energy disappears.
What actually moves output quality - and the small set of habits that beat clever one-liners every time.
A repeatable four-part structure for prompts that stay reliable as your product and models change.
Copy-ready building blocks - from role priming to output contracts - with annotated before/after examples.
