Nice! This solves a real problem. I have a drawer full of identical USB-C cables and no idea which ones support Thunderbolt. The menu bar approach is perfect for this :) You don't need a full app, just a glance when you plug something in.

Interesting that Matz built this in about a month with Claude. The limitations (no eval, no metaprogramming) basically define a 'compilable Ruby subset'.. similar to what mruby does but targeting native executables instead of embedded. The pragmatic approach of generating C rather than LLVM IR makes sense for a first version you get portability and debuggability for free.

Interesting to see this gaining traction so fast. The git-first approach for AI context is a smart differentiator from Obsidian, it lets you see exactly what the AI changed vs what you wrote.
