Yes. But only for the coding. The rest is still done by me (hardware testing, QEMU, debugging, instructions, ideas, and so on).

I have forked, cloned, and built (had to pin a specific nightly Rust for it to build). When I run it, it crashed at login; I reran it with VNC, was able to login as root, issue ls and uptime, but then it crashed. My AI is debugging...

so the built-in nano helps a lot, since the help output scrolled off the screen. I tried to use head, less, and more. I could redirect help output to a file (but until I found nano, could not page that). I also looked for dd.

The VNC UI seems generally stable, I was able to log in as all three users, and issue many commands.

Is there a bundled assembler or compiler. How can I write apps for this? Do you have a way to cross-compile and mount a shared folder or scp binaries in?

Hey. Sorry I couldn't reply sooner (I was asleep). Here's how it works: you put your files directly from your main OS into the "inyect" folder (where the `bin` folder and other items are located). You add your binaries there and then rebuild the ISO. That way, when you boot up MesaOS, your file(s) should be inside.

My AI wrote scripts to launch and attach. I was able to do a lot login in as root. One bug: when I run the ring3 demo, the shell stops accepting input.

In my fork, I've added ./experiments where I hacked together a shell wrapper for a no_std Rust app to implement head -<n>.

help > help.txt <script path>/head -2 help.txt

works. This shows how I can cross-compile code to run in the MesaOS shell. This is a workaround until I have better libraries/APIs for argc/argv handling, file I/O, etc. Fun!
