What is context engineering and why does it matter for AI?

Context engineering is the systematic practice of controlling the information AI models consume at runtime. It matters because AI outputs are only as reliable as their inputs. Without proper context engineering, AI systems hallucinate and produce inconsistent results.

How does context engineering prevent AI hallucinations?

It prevents hallucinations by ensuring AI retrieves data from governed sources with verified lineage, unified identities, and quality controls, eliminating incorrect or misleading information from the model's knowledge context.

What are the three data pillars needed for reliable AI context?

The three pillars are provenance/lineage for audit trails, entity resolution to unify identifiers into a single source of truth, and domain constraints to validate data against business rules before it reaches the AI model.
