Curious if there's a demo/screenshot on what questions developers should expect and what acceptable answers look like. Checked out the repo but didn't find the showcase.
Cool! I watched the demo. The concept makes sense. Quick thought: free-text answers might be high friction for adoption. Not sure if you'd consider various verification method, but something like multiple choice questions or "highlight the relevant code chunk" could be lower effort for the developer, and easier to evaluate programmatically too.
