I'm surprised there aren't more tools out there for starting a new project with some default config files. There's `cargo new` but it's Rust specific and very minimal. create-react-app is React specific. The only option I know of is cookiecutter. Surely it's a common problem?

I find it odd that people recommend Docker for sandboxing agentic coding tools. Isn't it easier to just create a separate user account on the machine? It's an established security boundary, and viewing output is easy (just make the user's home directory world readable).

It took me way too long to realise that Arc<Mutex<T>> is basically a way to create multiple &mut T references (with runtime constraints). This means that you can use plain &T and &mut T in the vast majority of your code. Most code doesn't need to care there's a mutex.
