Dex Semantics adds declarations to your analytical models, which capture row meaning, join nature, how numbers add up, and decisional assumptions. Thanks to this, Dex scores 80% on ADE-bench with Claude Sonnet 5.5, compared to 73.3% without Dex (25% fewer tasks failed). Declarations live in your models as code, not a third-party tool. Dex then helps your agent convert declarations into your Semantic Layer of choice.

Could you build this?
Partial A declaration layer and agent integration are buildable, but showing measurable accuracy gains requires real semantic-modeling expertise and benchmark-driven iteration.
What it would actually take: The product is a semantic-layer schema for analytical models that captures row meaning, join semantics, additivity, and assumptions, then exposes it to coding agents through files and tooling. Integrating with dbt, warehouses, and BI tools is conventional engineering. The hard part is designing declaration formats that actually reduce agent errors, which needs data modeling expertise and an evaluation harness like ADE-bench to validate gains.
