Best AI coding harnesses

... inside of Base Camp, so they will do work on a to-do in Base Camp, or they'll work, do work on a card. And it turns out that a collaboration tool that's optimized for asynchronous communication is actually the right format versus these harnesses are a little more like chat. And chat, which was, I mean, the original format for these things, is not the right thing because you're sitting around waiting. It entices you to sit around and wait, versus when you're dealing with something like Base Camp and you can just give an agent a to-do item, you don't expect to hear back immediately. So I don't know what the final form is gonna take, but I've been using all of the harnesses. So I use them inside of Herdr, and Herdr has panes. So oftentimes I'll run Claude up top, and then I'll run Codex down below, and then maybe I also have an OpenCode set up. But I will say just very recently, I found that the human in the loop is the limit here. So I've started setting up more automated systems. I've been building an Omarchy bot that can do more autonomous development on Omarchy that is just On a regular schedule process, all depending to do or PRs and issues, and then send me an email using the Hey CLI, and then I just get this email. Here's 12 PRs that are either ready to go or I think you should close. And then I just make the final determination there.

Yes, but in an exhilarating way. Like, one of the things I always loved about race cars was when I would stumble out of the car absolutely smashed and barely able to hold my head up, and I'd lay down on the garage floor and just think, "Holy fuck, I'm alive." That's the kind of exhaustion, mental exhaustion I'm feeling at moments with the agents right now.
`2:44:34`
It's physical. It's just... I mean, I bet it's the same thing with jujitsu, right? Like, it's actually satisfying to feel exhausted. It feels like you've applied yourself. And I feel that with the mental exhaustion you can get from agents.
`2:44:49`
Yes. If you drive in difficult conditions, especially if you drive in the rain, where you're constantly managing the thing right at the knife's edge. But most of the time, I just enjoyed the physical exhaustion.

It's funny. It's actually very similar with racing. There's some tracks, like Le Mans, where you get time to relax. There's the Mulsanne straights where it's kinda long. You're going fast, but in a straight line, you can take a breath. And then there are other tracks where it's just coming full on all the time, and you don't have any moment to relax, and you stumble out of the car after an hour in each, and it's very different how exhausted you are. And this is exactly what I'm finding with the agents too, that when you're running at max human capacity-... you're just constantly in a corner.
