Context engineering is the emerging successor discipline to prompt engineering, focused on managing the full context window including system instructions, metadata, API tools, and tokens — especially for agentic applications (2025 onward)
Summary
As AI systems grow more autonomous, the critical skill shifts from crafting a single well-worded prompt to architecting the entire information environment an agent works in, including system instructions, tool definitions, metadata, and token budgets all at once. This matters because the quality of an agent's output now depends less on the question you ask and more on how you structure everything it can see and act on.
Dependents
These beliefs depend on this one:
- IN context-engineering-inherits-structural-limits-of-inference-control — Context engineering, as the successor discipline to prompt engineering, inherits the structural limits of inference-time control: the same self-undermining dynamics — prompt fragility compounding with context expansion while the authority hierarchy serves as both defense and attack surface — apply to context engineering's broader scope of system instructions, retrieval context, token budgets, and provenance tracking, meaning the discipline's operational practices manage but cannot resolve the fundamental vulnerability.
