Context engineering: the art of feeding LLMs

You build a RAG pipeline, connect it to Azure OpenAI, and the answers come back… meh. Generic. Sometimes it ignores the context you sent. Sometimes it makes things up. The model is powerful, but input quality usually determines most of the result. Context engineering is the discipline of assembling that input so the model gives you what you actually need. It is not just “prompt engineering” with a fresher label. It is engineering: structure, constraints, and trade-offs. ...
