So it's a (somewhat more) sane version of Yegge's Gas Town? https://steve-yegge.medium.com/welcome-to-gas-town-4f25ee16d...

author here! I am not sure if I would phrase it as sane Gas Town. The design constraints are very different. For example, I tried to optimized for output density (the number of tokens that I didn't have to rewrite because the output quality was bad), instead of treating it as a distributed system and coordination problem. SGAI, for example, runs one agent at a time - maybe one day it will run more agents in parallel, but only as much that I can obtain better outputs (not more outputs).

Also, I am not a cryptocurrency enthusiast - and therefore, I wouldn't accept creating a memecoin out of it.

I have been working on this for my own use until recently, when I shared with the rest of the team, and we thought it would be nice to let the world see it.

I have been interested in autonomous code development for quite some time (at least since March/April 2025) - and summer '25 is when I felt the models were good enough to be pushed to autonomy.

I wrote a bit about it[0], and sgai is the incarnation of my take on AI autonomous coding.

sgai is not even v0 yet, a lot of work to be done to improve its implementation - but I think it should be usable enough for those willing to give it a try.

Sgai (pronounced "Sky") - That's a bit of a stretch

You know, I tried to convince people of a number of various other pronunciations. But when we saw it written down, everyone just naturally pronounced it "sky." My natural impulse was to avoid it, since there are already a ton of AI-related things called Sky, but I think I've accepted that it was inevitable.

Besides -- and I've obviously thought about this a little too much -- when you actually say the word "sky," are you using a hard k? After saying it out loud to myself about a billion times (and long after the word lost all meaning) I think I actually use a hard g.

Depends on the language no? Works in German

Interesting license choice, modified MIT it seems, with this additional clause:

> No licensee or downstream recipient may use the Software (including any modified or derivative versions) to directly compete with the original Licensor by offering it to third parties as a hosted, managed, or Software-as-a-Service (SaaS) product or cloud service where the primary value of the service is the functionality of the Software itself.

Doesn't that kind of conflict with the "including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software" part of regular MIT, which your custom license also includes for some reason?

I think you might be better of with just not trying to do it "kind of open source but also not" and just say "Copyright 2026 Sandgarden.com" or whatever, instead of the mix of proprietary and open source. Then you get 100% "full control" over what people can do with the source, and don't have to worry about anything when it comes to licensing :)

author here! the decision was mine; if anything, the senior leadership was fine with an unencumbered open-source license. What I didn't want was someone using it to make a business out of this tool without me in the mix.

In a sense, a futile effort; because if you reverse engineer a nlspec and rebuild it, then you can have it with any license you may want.

I wasn't doubting it wasn't you making the decision! :)

I was more curious why go with modifying a FOSS license (which clearly isn't the right choice if you want to prevent others from doing whatever with it) instead of just straight up keeping full copyright to yourself/the company and a "regular" license?

Then you get exactly what you want, without also sending double-messages about that people can do whatever they want, which is what you're trying to prevent.

He said why, he wanted to open source it with the mentioned exception.

I think there are also licenses that do that, and revert to full MIT after some time, but the author decided to roll their own.

What’s the problem with that? He can license it however he wants and the reason he mentions is perfectly valid tbh

Legal writing is like code: it's a specific domain, that requires special expertise to write properly.

If you see a problem with a non-programmer writing code, then you should see a problem with a non-lawyer writing licenses.

Terrible decision.

OSS licenses (and existing commercial ones) are tried and true (and re-used) for a reason, while your license very well may not even hold up in court!

I mean, I'm not a lawyer, and I assume you aren't either ... would you hire someone who isn't a programmer to write your code for you? Then why are you doing your own lawyering without a law degree?

Very nice, the automated setup instructions for opencode are a genius touch, more people should do that.

Is this already your daily driver for coding projects?

author here! it is my daily driver for quite some time; with that said, its current shape is a bit of a more recent development. Initially, I would manually handle jj workspaces and fire out screen/tmux sessions; but over time, I figure it would be nice to have an UI that I could browse from anywhere through a VPN.

It does take some investment -- by adding customizations through the overlay folder (`sgai/` directory at the root of the repository) -- but eventually it should be able to code in a way that you would approve in a PR.
