With products coming out like this, many claim to do basically the same thing. How is this better than Claude Code's built in agent orchestrator? Do I need 100 agent types? How do I know the trained agents here are somehow better? Specialization doesn't equate to "better" in every case. I want to see the light but at this point it feels like these kinds of projects need a better way to benchmark how they are improving on the available state of the art. It feels like in 2018, a new browser state management tool emerging. Why does this exist?
