azure-prepare plans infrastructure by analyzing source code and mapping it to one of 5 host types (containerapp, appservice, function, staticwebapp, aks). It has no logic to plan the remaining 43 resource types in this skill — VNets, Firewalls, VPN Gateways, VMs, Service Bus, Key Vault, etc. It cannot look at a workload description and decide "you need a hub-spoke VNet with NSGs and a Firewall."
This skill fills that gap: infrastructure-first planning for platform engineers, where the input is a workload description (not code) and the output covers all 48 resource types. Renaming to azure-enterprise-infra-planner makes this distinction clear.
