The 200 dollar plan weekly limit runs out in like half a day or a day if you use it heavily with subagents. The 20 dollar plan is a blip.

You can build a lot of stuff this way. You can also waste it. You need good people who will use it well and usefully.

What are you doing with your subagents? I find that as long as I use Opus at the top level and Sonnet/Haiku for subagents I generally don't run into usage limits.
