alt Hacker NewsAh do you mean sub-agents? I do understand that if I summon a sub-agent and give it e.g. code reviewing instructions, it will not fill up the context of the main conversation. But my point is that giving the sub-agent the instruction "review this code as if you were a staff engineer" (literally those words) should cover most use cases (but I can't prove this, unfortunately).
I do think you're right that you should be cautious about writing too convoluted sub-agents.
I'd rather use more of them that are brief and specialized, than try to over-correct on having a single agent try to "remember" too many rules. Not really because the description itself will eat too much context, but because having the sub-agent work for too long will accumulate too much context and dilute your initial instructions anyway.
