My point is pi-coding-agent [1] is a very well designed and implemented open source project that we all can learn from as software engineers. His blog post about his decision making [2] is also very well written.

I should've given original links instead of noisy HN threads.

pi-conding-agent itself is not a product yet and it won't have much value to end users other than those using the products built on top of it.
