Our review of Cube agent

Cube does a good job of connecting to your warehouse and bootstrapping semantics from your dbt project, but you still have to carefully review and correct what it generates. Context lives across several parts of the UI — rules, semantics, and connections — which can make maintenance feel scattered. In our experience the agent felt slow and deep dives into the model were not straightforward.
