Datacenter designs become codified rules, retrieval of hundreds of past designs, and a fleet of specialist agents that size fabrics, render configs, and generate BOMs — delivering a claimed 10x productivity speedup and turning a 6‑week sizing exercise into minutes for hundreds of analyses now deployed in production. The system uses deterministic IP addressing, capacity models, and a grounding/validation layer so agents draft real, deployable topologies but cannot yet own end‑to‑end orchestration; humans remain approvers. Expect autonomous sizing, grounded agents, and validation as the remaining hard problem.
