Prompt engineering
The practice of designing prompts to elicit reliable, high-quality outputs.
Prompt engineering is undervalued in 2026 — partly because the term has been used to describe both serious work (system prompt design, output structuring, few-shot example curation, constrained decoding) and trivial work ("let me try rewording it"). The serious version is real engineering with measurable outcomes against an eval harness; the trivial version is folklore.
