I would not call this a unix environment. It does not run elf binaries. It does not have a kernel. All of the commands are vibecode-reimplementations in typescript.
Yep, the title of the OP is misleading that way.
P.S. `curl -fsSL https://claude.ai/install.sh | bash` works.
You can run real Claude Code and it can use Shiro's tools
like a normal Linux system.
user@shiro:~$ curl -fsSL https://claude.ai/install.sh | bash

The gcc stub surprised me:
user@shiro:/tmp/hn$ cat main.c
#include <stdio.h>
int main()
{
printf("Hello\n");
}
user@shiro:/tmp/hn$ cc main.c -o main; ./main
Hello, World!
user@shiro:/tmp/hn$ cat main
#!/bin/sh
echo 'Hello, World!'gcc seems to be a funny stub that generates an "executable" that prints "Hello, World!" if the input file fuzzy-matches a hello world, and otherwise prints nothing.
Seems to be a few simple regexes: to "compile" you need a "main(" with either int or void before, and to trigger the hello world behavior you need printf( and a "hello" inside quotes. But that seems to be it:
void main(
//printf(" hello"> I built a browser-native Unix environment
On GitHub, it says Claude built it.
