OSX Harness

I believe that best harness existing today is a plain Linux system. Cli tools already in place, extremely powerful and been designed to process text and perform any kind of task.

This harness been created to give a security-isolated workspace for running Pi.dev and BB without touching the macOS host

• installs necessary packager on machine using Brew
• configure Ollama with gpt-oss:20b
• spins up a Lima virtual machine with a Debian 13
• prepares that VM , installs Pi.dev and BB inside VM
• configures the Pi.dev agent to talk to a local Ollama server

Brew must be installed

brew bundle --file=Brewfile

mise build

alias pi="limactl shell --sync . bb-rig mise trust -y; limactl shell --sync . bb-rig pi"
cd $HOME/Projects/amazing_project
pi

It will sync your current directory to VM and after session you will be able to accept or reject changes
