That's why people "meet".

However, a "standup" was invented to solve a particular problem: people, in isolation, do not always understand that they are stuck, and talking it through lets fellow humans identify their challenge.

The stand up part is mostly to encourage keeping it concise and short, so you only focus on what is actionable between all participants (waiting on a review, I am looking at this for the 3rd day and I think I am ok, anyone wants to brainstorm this...).

With agents, they get similarly stuck (completely or in a loop), and with each keeping a different context at any given moment, they might still be able to help each other.

Obviously, their memories are not like humans' (there is no "I touched that two months ago, let's discuss after"), but there might be a different sweet spot where having them sync regularly (every 1M tokens instead of daily?) might be useful as they are also parallelizing work.
