The division of labor gets much easier to sustain when the handoff itself is explicit: who owns the next step, what evidence came back, and which decision still belongs to the engineer. I work on Alook, where people and local agents can share one room and keep those messages and follow-ups visible across tools: https://alook.ai. Copilot and Claude Code still do their respective jobs; the shared room is the coordination layer around them, not a replacement for repository evidence or human approval.
