What does Context Engineering mean?
The practice of designing what an AI system sees before it answers: instructions, retrieved facts, tools, memory, examples, state, and the boring metadata that keeps the magic from falling apart.
Context engineering means treating the context window like a product surface. You decide which information, tools, examples, and constraints the model gets for a task.
Origin and usage
Gained traction in 2025 as builders argued that reliable AI apps need more than clever prompts; they need managed context systems.

Practitioner term amplified by builders in 2025 and later discussed in survey literature; not a single-origin academic phrase.
Examples
- The prompt was fine; the failure was context engineering.
- Context engineering is why the agent saw the right repo notes instead of guessing from stale memory.
