There is such a clear lack of innovation drive in this field. Every lab just copies what the other does. One of the most baffling things to me is how the once-upon-a-time good developer instinct to make everything reusable, testable, and deterministic is just getting lost into a sea of markdown begging a language model to please act a certain way. For example this repository has a "skill" definition that consists in…

Earlier quoted context omitted.

I remember a popular hn thread few yrs ago where a dev replaced their whole deployment pipeline with a prompt. it was widely ridculed at that point but now i am not so sure.

Well, that makes one of us. Replacing deterministic processes that work with lossy processes makes no sense. You’re literally reinventing the wheel every single time, what are you talking about?

Yeah. LLMs have their place and they are definitely super human at short length tasks, but I feel like a large part of the "AI boom" is trying to get the computer to do something in a worse way then it already could.

Is there a reason why so many of these agent harness are written in node.js?

codex is written in rust fwiw smol has implementations in Go, Python, Clojure, PHP https://github.com/smol-env/smol out of the box an agent only needs to be able to do http requests and call tools (which might again be just http requests or shelling out) there is no inherent reason for why an agent has to be in JavaScript or Typescript but they are popular languages and come with runtimes and libraries for http reque…

I have read the underlying paper, and found it may be useful, but not that useful. For those who want to know what it achieves: it adds hot-reload and dynamic enable/dispose capabilities to a plugin system, like the one in Pi agents, though they push the boundaries further, to the UI components and so on. For those who want to know what it does: if you have some PLT knowledge, ask your agent to explain the algebra to…
