The anatomy of a well-engineered prompt
Breaking a prompt down into its actual structural parts, and why a well-organized prompt is a context engineering artifact, not just good writing.
Few-shot prompting and in-context learning
How showing a model two or three examples inside the prompt can change its behavior more than paragraphs of instructions — and why this even works at all.
Chain-of-thought and giving the model room to think
Why asking a model to "think step by step" measurably improves accuracy, what's mathematically happening when it does, and how reasoning traces are just another form of context.
Lost in the middle: why context ordering matters
The real, measured research finding that models pay less attention to information buried in the middle of a long context, and what to actually do about it.
