[Bug] Sub-agents terminate immediately due to prompt size exceeding context window

Bug Description
When Claude launches a bunch of sub-agents, they all terminate immediately, with no tool uses, no nothing. And when I asked Claude about it, it said that the prompt was too large to use, and so all the agents terminate immediately. This bug has been happening for a long while; each time Claude tries to launch sub-agents.
