Awesome to see this. Like a few others here, I hand-rolled (well, Codex-rolled) something similar that works great for me. I keep going back and forth on open-sourcing it, but my hunch is people won't really adopt these kinds of things anyway.

Everyone ends up with a workflow shaped really tightly around how they work, and it's gotten so cheap to just build and evolve your own as the models and harnesses change that picking up someone else's stops making much sense.
