Ask HN: How did you set up a multi-agent orchestration for personal use? (opens in new tab)

I am about to start a bigger project with several subprojects and want to be a human in the loop of otherwise fairly automated loop, which should ideally use different agents for different roles (coding, design, testing, supervision, etc). I know this approach is becoming increasingly common and I wonder if there's already some tooling that facilitates that? Or do you simply use some specific model as a coordinator?
