Transcript context
…Yeah. So basically there needs to be like this kind of house stack and owning the whole loop. I think that is very well established. And it sounds like you might be like sharing more about that in the future, right? Yeah. I think we’re excited to do We’re gonna talk about Symphony in a little bit, but like the way we distribute it as a spec, which I think folks are calling Ghost Libraries on Twitter. This is like a such a cool name. It does mean it becomes much cheaper to share software with the world, right? You define a spec, how you could build your own specifying as much as is required for a coding agent to reassemble it locally. The flow here is very cool. Like we have taken. All the scaffolding that has existed in our proprietary repo spun up a new one. Ask Codex with our repo as a reference. Write the spec. We tell it. Spin up a team ox spawn a disconnected codex to implement the spec. Wait for it to be done. Spawn another codex and another team ox to review the spec com or review the implementation compared to upstream and update the spec so it diverges less. And then you just loop over and over Ralph style until you get a spec that is with high fidelity able to reproduce the system as it is. It’s fantastic. And you’re basically, you’re not really adding any of your human bias in there, right? That’s correct. A lot of times people write a spec and be like, okay, I think it should be done this way, and you’ll riff on something. And it’s no, the agent could have just handled it like you’re still scaffolding in a sense, right? I want it done this way. It can determine its spec better.…
