Definition
Plain language
A system that lets several AI agents work on the same live system at once by tapping the loser of a clash on the shoulder instead of throwing away its work.
As stated in the literature
A concurrency-control framework for multi-agent systems that replaces locking and abort-restart with notification-and-repair, using agent self-healing, saga-style compensating actions, fixed precedence ranks, and trajectory logs to achieve serializability.
Why it matters: It lets multiple AI agents safely operate on the same live system at once without wasting work or corrupting shared data.
For example, if two AI agents try to edit the same shopping cart at once, CoAgent tells the lower-priority one to adjust and repair its work rather than discarding everything it did.
