This is my goto SDK, it comes in multiple languages too. I'm going to be wrapping the Go ADK in CUE Nov/Dec, along with Dagger, and rebuild my personal harness from scratch which I worked on last Nov/Dec.

ADK has a graph/workflow concept too: https://adk.dev/graphs/

Are you this guy? https://github.com/hofstadter-io/hof/tree/_next Third time I've seen CUE mentioned in this context in as many days.
