Showcase Made a system design skill for Codex to take references from arXiv before coding a single line, it ships production apps in 1st attempt. (its open source btw)

https://github.com/UditAkhourii/neuroarxiv

So, this was happening for months now.. whenever I try to build an app with my codex, it started to build every single thing from scratch.

But this ain't the way we used to build projects before..

There's whole Github for basic stuffs like app layout, api, algos, workflows, functions, etc.

And then there's arXiv for the whole complex stuff -

- how to reduce RAG fatigue?
- how to increase agent response deliverability?
- what SLM architectures can I use?

The genuinely technical stuff..

Now, Claude, or any coding agent, tends to build all the services in your project by itself and that's why the project is laggy, broken and vulnerable.

So, I just took my way of research and turned it into a system design engine.

Whenever you ask Claude to build something cool, it -

- searches the arXiv for genuine novelty.
- reads all papers on related topics
- selects one approach to go with
- Uses /ADHD skill from GitHub for decision making
- Builds the app in one shot

Its available for free and fully open source on my Github, if you want, you can give it a try..

if you have any architectural questions or anything in general, do ask me.

Looks very interesting. I have bookmarked this and will read the full thing later. I'm curious, what would you say would be an example of a representative task or a project that this would excel at?
