I’m constantly using code agents to work on feature development and they are constantly getting things wrong. They can refactor high level concepts but I have to nudge them to think about the proper abstractions. I don’t see how a multiagent flow could handle those interactions. The bus factor is 1, me.

Most tests people write have to be changed if you refactor.

Upgrades, API compatibility, and cross version communication are really important in some domains. A bad design can cause huge pain downstream when you need to make a change.
