Yah. You are describing basically every youtube I have seen on openclaw use-cases: news digests, morning debriefs, etc. I am sure this is useful but not something that you specifically need sub-agents for.

In the context of coding assistants sub-agents are mostly useful to breakdown a more complex tasks in smaller chunks so that refactoring can be done without loosing context. But this is a completely different problem domain that requires burning through a lot of tokens.

In theory I get why it might be useful but what I am trying to say that applications at the moment are limited due to the fact that it is just overkill for most AI interactions.
