Context Engineering

Context Engineering is the practice of designing, structuring, and optimizing the prompt context window to maximize the accuracy and efficiency of Large Language Models. It focuses on how raw data, historical messages, and systemic rules are retrieved, formatted, and pruned before being sent to the model.

Frequently Asked Questions

How does context engineering differ from prompt engineering?

Prompt engineering focuses on instruction phrasing and templates. Context engineering focuses on the data infrastructure and retrieval logic that feeds the prompt.

What is a common technique in context engineering?

Vector-based retrieval filtering, reranking, and dynamic context summaries to avoid exceeding token limits.

FAQ: Real-time context engine, agent memory, and retrieval

AI agents are getting better at reasoning, planning, and using tools. But even the smartest model can give a bad answer if it has the wrong context, stale data, or too much irrelevant information. That is why context engineering is becoming a critica...
