Summary

The Cloud Data Agent Builder gives data analysts a user-friendly tool to add advanced context engineering to a custom-built agent. The goal was to meet data experts where they were and give them the tools to build high-accuracy data agents that could be shared with their colleagues.

Currently in private preview, initial evaluations showed a promising +10-20% increase in agent accuracy when using the structured context of the builder.
