I had the same question. I think this is in the space of being like the 'trillian' or 'matrix' of ai agents, using multi provider coding agent from a single interface plus some bells and whistles.

But I think within claude code and codex subagent support has improved a lot lately and it doesn't seem this would improve that much over that native support if you only use one provider.

The benefit is not spinning up sub-agents, but spinning up parallel workstreams. They basically took 90% of the friction out of working with and using worktrees. I was using Linear a lot (and enjoying it!) for my issue tracking, but at some point I realized it's more productive to just create a new worktree in Conductor for any bug/feature and cut out the middleman.
