“If you think that code is context, code is prompts, it’s better from the agent behavior perspective to be able to look in a package in directory X, Y, Z, and it not to have to page so [00:40:00] deeply into directory if you C, because they have the same structure, use the same language, they have the same patterns internally.”

Transcript context
…Yeah, that was my thing. Okay, where do we see right now Codex has started Codex Model, then CLI, now there’s an app, app can let me shoot off multiple Codex is in parallel, but there’s no great team collaboration for Codex. And it seems like your team had some say into what comes out, right? So you talked to ‘em, codex kind of was a thing. From there, if you guys are on the bound, what stuff that like, you might not focus on, but what do you expect other people to be building, right? So people that are like five x 50 Xing. Should you build stuff that’s like very niche for your workflow, for your team? Should it be more general so other people can adopt? Is there a niche there? ‘Cause part of it is just okay, is everything just internal tooling? Do we have everything our own way? Like the way our team operates has our own ways that we like to communicate or is there a broader way to do it? Is it something like a issue tracker? Just thoughts if you wanna riff on that. I think TBD we have not figured this out in a general way. I do think that there is leverage to be had in making the code and the processes as much the same as possible. If you think that code is context, code is prompts, it’s better from the agent behavior perspective to be able to look in a package in directory X, Y, Z, and it not to have to page so [00:40:00] deeply into directory if you C, because they have the same structure, use the same language, they have the same patterns internally. And that same like leverage comes from aligning on a single set of skills that you’re pouring every engineer’s taste into to make sure that the agent is effective. So like in our code base, we have, I think, six skills. That’s it. And if some part of the software development loop is not being covered, our first attempt is to encode it in one of the existing setup skills, which means that we can change the agent behavior. Yeah. More cheaply than changing the human driver behavior. Yeah. Have you ever, have you experimented with agents changing their own behavior?…
