I just have worktrees set up with a script that pulls in my venv and git hooks so each one runs isolated. Sometimes I miss having a good way for agents to share some information between them, but that's not often.
I do think agent orchestration is the future, but I don't think it's there yet.
Anyone I talked to who actually built software found them to be bunk. Occasionally they work, but mostly they just burn tokens.
The only people I know still hyped on this approach were managers who were detached from actual engineering, primarily producing bespoke dashboard and tools.
