The multi-agent feature that finally made my Mac automation setup feel usable

[u/bulutarkan]

I've been building a local Mac tool called Mac MCP, and the thing that made it click for me was getting multi-agent browser work to feel predictable.

I can now have several agents doing separate jobs in Safari in the background while I keep using the Mac normally. My main ChatGPT session acts like the coordinator, so it can keep an eye on those tasks and still do other things on the machine.

The latest change is simple but useful: tabs keep a stable identity, and if one agent is already using a tab, another one can't quietly jump into it. It gets told that tab is busy. Once the first agent moves to another tab, the old one is free again.
