The Complete Agent Stack
A 14-part guide to what a data agent needs before people can rely on its answers.
Most data agents work in the demo and start failing within a couple of months. The model rarely changes in that time. The business, the data and the definitions around it do, and an agent without the right context has no way to keep up.
The complete agent stack is how we think about building agents that last. It has four layers, and each guide in this series covers one feature in one layer. Read it from the foundation up, or go straight to the layer you're working on.
Each layer builds on the one below it, and the improvement loop feeds back into the ontology.
Layer 1: Ontology
Your data described clearly, with permissions enforced outside the agent.
