Every time I mention coding agent harnesses, somebody shows up asking: “but why don’t you use Pi?” or “why not Oh-My-Pi?”

I hate that question when it comes like that.

Not because I have anything against Pi. I don’t. The problem is that almost nobody explains the why. What is the concrete benefit? What problem does it solve better than Claude Code or OpenCode? Which use case is clearly better there? Which limitation does it remove?
