Azure CLI (az) AI Skill Guide (Claude)

Overview & Engine Architecture

The Azure CLI (az) calls Azure Resource Manager (ARM). Work is scoped by tenant → subscription → resource group → resource. Auth is interactive login, service principal, managed identity, or federated OIDC (GitHub Actions). Agents always resolve tenant, subscription, and location before mutating—Azure often returns NotFound / “subscription doesn’t exist” when the real issue is wrong context or missing RBAC, not a missing resource name.
