Born out of my frustration with powershell’s slow startup and confusing syntax I have long wanted to build a shell and scripting language in .NET. I have been working on it for a long time and thanks to Claude, I was able to finally get it over the line. I daily drive it as my shell on Windows, and really happy with it so far.Please try it and let me know where it can improve!

Could you build this?

Partial A basic CLI wrapper or scripting language can be guided by AI, but building a fully featured, high-performance interactive shell with custom typing, job control, and terminal emulation in .NET is non-trivial.

What it would actually take: The architecture requires a lexer, parser, type checker, and bytecode/interpreter compiler in .NET, along with a custom Read-Eval-Print Loop (REPL) handling VT100 ANSI sequences, autocompletion, and syntax highlighting. The hard parts are OS process management (pipes, redirection, signals, and background/foreground job control across Windows and POSIX) and typed pipeline semantics. This requires solid expertise in compiler construction and cross-platform operating system internals.
