It is surprising that Claude would use that many subagents, since we prompt Claude not to use subagents unless asked. You can verify this actually by intercepting the network traffic to see the system prompt.
It is also surprising that a few agents would cause you to run out of tokens that quickly.
1. Which model were you using?
2. Which plan are you using? Pro/Max/Ultra
3. Can you run /bug in that session and share the feedback id here? Happy to debug.
I was using Fable 5.2 on Max 5x -- I had Max 20x a few months ago but had to downsize.
I did ask a lot of it, but didn't expect it to fan out that far, nor even for that to be quite so expensive.

I used one of the Fable resets to continue on. That got me through it and I was satisfied with the result, I just can't believe I needed one for that task.
This use-case should be extraordinarily normal, it's insane for it to cost so much.
