Whether a sub-agent should inherit the full context of the main thread depends on the situation.

“I think that probably the weirdest thing about how I think about context right now is when you split out to a sub-agent.”

“Because sub-agents can benefit from inheriting your entire context of the main thread or not. Uh, sometimes, uh, there's a regular disagreement on, on that, and then sometimes you want to condense what the sub-agent does, and researchers put it back onto the main thread.”
