Agent coordination layer
An agent coordination layer is shared infrastructure that lets multiple AI coding agents, across developers, machines, and tools, work on one codebase without duplicating work or breaking each other's interfaces, by sharing intent, contracts, claims, and decisions in real time.
Coordination is the pre-commit problem. Version control shares finished code; a coordination layer shares what agents are ABOUT to do, what each is building now, which interfaces exist and who depends on them, which areas are claimed, so conflicts surface before the work is done twice or done incompatibly.
The test of a coordination layer is what it refuses to carry: it should move coordination metadata, never source code. That keeps it safe to span machines and organizations.
