Context Engineering Best Practices: A Hands-On Guide
Blog post from Hex
In the realm of AI analytics, context engineering is emphasized as a crucial practice for ensuring that AI systems produce accurate and reproducible results, rather than relying solely on prompt engineering. While prompts determine how to ask questions, context engineering focuses on what the AI knows prior to answering, involving the endorsement of trustworthy tables, creation of workspace rules, and development of semantic models. This structured environment allows AI to accurately interpret data, reducing errors such as inconsistent metrics, incorrect joins, and confidently wrong answers. Hex's State of Data Teams 2026 report highlights trust as a primary concern in AI adoption, with context engineering identified as a key solution to enhance AI's reliability. The process of building context is iterative, involving layers from endorsed tables to observability mechanisms, allowing teams to progressively deepen their AI's understanding and improve data-driven decision-making. By prioritizing context over prompts, data teams can ensure more consistent and trustworthy outcomes, making AI analytics more reliable and actionable.
