Prompt engineering that actually works (and what does not)
Prompt engineering has a bad reputation because most of it is superstition. But underneath the "you are a helpful assistant" cargo-culting, there are a handful of techniques that reliably work — and they're grounded in how the model actually behaves. Let me separate the real patterns from the folklore. These are the ones that move quality measurably, not the magic phrases people paste around…
Prompt engineering carries a negative reputation due to superstitions, but there are techniques that reliably improve quality. These techniques are based on how the model works. The model predicts the next token based on everything before it, so prompting sets up a context for the most probable continuation. The real techniques that improve quality include being specific about output, using examples (few-shot), letting the model think before answering, assigning a purposeful role, and decomposing hard tasks into smaller prompts.
Politeness, threats, and vague superlatives do not work and are just noise. The key is to think of prompts as specifications rather than wishes. The clearer and more constrained the specification, the more reliable the output. When a prompt underperforms, focus on adding precision instead of magic words.
