CI typically seems much more dependent on bash/unixy sorts of tools to get things done. This seems to not really support that workflow, requiring code to define pipelines instead.
If it's intended to do CI, how do you deal with CI-style tasks, like shuffling around files between pipeline steps? Or the corollary, what does this do that makes it easier to do CI in practice than with typical unix command based workflows? Inherently, it seems like "Create a golang script that can start a subprocess that runs a test suite" is more overhead than "run a test suite".
At first glance, it looks like more of a competitor to, say, AWS step functions, but it doesn't sound like that's what you're targeting.
