Not the person you replied to, but I'll stress the point that it is not just what you can add that Claude Code doesn't offer, but also what you don't need to add that Claude Code does offer that you don't want.

I dislike many things about Claude Code, but I'll pick subagents as one example. Don't want to use them? Tough luck. (AFAIK, it's been a while since I used CC, maybe it is configurable now or was always and I never discovered that.)

With Pi, I just didn't install an extension for that, which I suspect exists, but I have a choice of never finding out.

"hey, build a connector for z.ai GLM-5"

Can't do that with Claude =)

Claude code includes a large system prompt with every request while tool like pi does not. This could save tokens resulting in lower costs.
