AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

This skill guides users through a 7-phase pipeline to design and deploy Azure infrastructure. It processes workload descriptions to generate Bicep or Terraform code, supporting both greenfield deployments and additive updates to existing environments. The process includes research, planning, user approval, and automated validation using security and syntax checks before deployment.

What it does

  • Extracts insights from workload descriptions to inform infrastructure planning.
  • Researches Azure best practices and service-specific documentation.
  • Generates infrastructure plans and corresponding Bicep or Terraform code.
  • Validates generated IaC using syntax checks and security scanning tools.
  • Supports additive deployments for existing environments without modifying referenced resources.
  • Manages multi-resource topologies including networking, identity, and compliance configurations.

When to use it

  • When planning Azure infrastructure from a workload or architecture description.
  • When designing hub-spoke networks, landing zones, or multi-region topologies.
  • When setting up networking components like VNets, firewalls, and private endpoints.
  • When generating subscription-scope or multi-resource-group infrastructure code.

Advantages

  • Follows a structured, gated pipeline to ensure plan approval and code validation.
  • Integrates security scanning and syntax validation into the generation workflow.
  • Provides support for referencing existing resources to avoid accidental recreation.
  • Utilizes specific Azure schema data to ensure accurate resource definitions.

Usage examples

“Plan Azure infrastructure for a hub-spoke network with firewalls.”
The agent initiates the 7-phase pipeline, researching networking best practices and generating the corresponding IaC for the requested topology.
“Architect an Azure landing zone.”
The agent guides the user through requirements extraction and resource planning, resulting in a structured infrastructure plan and Bicep or Terraform files.

Workflow (Start Here)

Follow the step-by-step instructions in workflow.md to execute the 7 phases of infrastructure planning and provisioning.

Architecture

The skill runs a 7-phase, gated pipeline. Input is triaged into one of two flows:

  • Greenfield — only new requirements; run the phases straight through.

  • Referenced (brownfield) — the user supplies something that already exists (a live resource / resource group / subscription, IaC or an infra plan, or a requirements doc). The same phases run, plus referenced-workload.md: existing resources are inventoried and referenced (never recreated), the new workload is wired into them, and Phase 7 deploys additively (incremental only — never modifying or destroying the referenced resources).

Every phase advances only after its gate passes. Phase 5 requires explicit user approval; Phase 6 is a hardened, self-verifying gate — the generated IaC must be secure-by-default, pass local validation (az bicep build / terraform validate) with zero errors, pass a checkov security scan with no unresolved high/critical findings, and the skill must show the command output and emit a completion self-check before advancing; Phase 7 requires an explicit, risk-acknowledged deploy confirmation.

Networking (Connectivity) Pairing Constraints

Azure Bastion
Paired WithConstraint
VNetRequires a subnet named exactly AzureBastionSubnet with minimum /26 prefix.
Developer SKUDoes NOT require AzureBastionSubnet or public IP. Deploys as shared infrastructure. Only connects to VMs in the same VNet.
Public IPRequires Standard SKU public IP with Static allocation.
NSGNSG on AzureBastionSubnet requires mandatory inbound (HTTPS 443 from Internet, GatewayManager 443) and outbound rules (see Bastion NSG docs).
VMsTarget VMs must be in the same VNet as Bastion (or peered VNets with Standard/Premium SKU).
Azure Firewall
Paired WithConstraint
VNetRequires a subnet named exactly AzureFirewallSubnet with minimum /26 prefix.
Basic TierAdditionally requires AzureFirewallManagementSubnet with /26 minimum and its own public IP.
Public IPRequires Standard SKU public IP with Static allocation.
Firewall PolicyCannot use both firewallPolicy.id and classic rule collections simultaneously. Policy tier must match or exceed firewall tier.
ZonesIn zone-redundant mode, all associated public IPs must also be zone-redundant (Standard SKU).
Virtual WANAZFW_Hub SKU name must reference virtualHub.id instead of ipConfigurations.
VPN Gateway
Paired WithConstraint
VNetRequires a subnet named exactly GatewaySubnet with minimum /27 prefix. Use /26+ for 16 ExpressRoute circuits or for ExpressRoute/VPN coexistence.
Public IPBasic VPN SKU requires Basic public IP. VpnGw1+ requires Standard public IP.
Active-ActiveRequires 2 public IPs and 2 IP configurations. Only supported with VpnGw1+.
Zone-RedundantMust use AZ SKU variant (e.g., VpnGw1AZ). Requires Standard SKU public IPs. AZ SKU cannot be downgraded to non-AZ (one-way migration only).
ExpressRouteCan coexist with VPN gateway on the same GatewaySubnet (requires /27 or larger). Not supported with Basic SKU. Route-based VPN required.
PolicyBasedLimited to 1 S2S tunnel, no P2S, no VNet-to-VNet. Use RouteBased for most scenarios.
Basic SKUBasic VPN Gateway does not support BGP, IPv6, RADIUS authentication, IKEv2 P2S, or ExpressRoute coexistence. Max 10 S2S tunnels.
GatewaySubnet UDRDo not apply UDR with 0.0.0.0/0 next hop on GatewaySubnet. ExpressRoute gateways require management controller access — this route breaks it.
GatewaySubnet BGPBGP route propagation must remain enabled on GatewaySubnet. Disabling causes the gateway to become non-functional.
DNS Private ResolverDNS Private Resolver in a VNet with an ExpressRoute gateway and wildcard forwarding rules can cause management connectivity problems.
DNS Zone
Paired WithConstraint
Domain RegistrarNS records from properties.nameServers must be configured at your domain registrar to delegate the domain to Azure DNS.
App ServiceCreate a CNAME record pointing to {app-name}.azurewebsites.net for custom domains. Add a TXT verification record.
Front DoorCreate a CNAME record pointing to the Front Door endpoint. Add a _dnsauth TXT record for domain validation.
Application GatewayCreate an A record pointing to the Application Gateway public IP, or a CNAME to the public IP DNS name.
Traffic ManagerCreate a CNAME record pointing to the Traffic Manager profile {name}.trafficmanager.net.
Child ZonesDelegate subdomains by creating NS records in the parent zone pointing to the child zone's Azure name servers.
Private DNS Zone
Paired WithConstraint
Virtual NetworkMust create a virtualNetworkLinks child resource to link the DNS zone to each VNet that needs resolution.
Private EndpointUse a privateDnsZoneGroups child on the Private Endpoint to auto-register A records, or manually create A record sets. One DNS record per DNS name — multiple private endpoints in different regions need separate Private DNS Zones.
VNet Link (auto-registration)Only one Private DNS Zone with registrationEnabled: true can be linked per VNet. Auto-registration creates DNS records for VMs in the VNet.
Hub-Spoke VNetLink the Private DNS Zone to the hub VNet. Spoke VNets resolve via hub DNS forwarder or VNet link.
PostgreSQL Flexible ServerFor Private Endpoint access, zone name is privatelink.postgres.database.azure.com. For VNet-integrated (private access) servers, the zone name is {name}.postgres.database.azure.com (not privatelink.*). Referenced via properties.network.privateDnsZoneArmResourceId.
MySQL Flexible ServerFor Private Endpoint access, zone name is privatelink.mysql.database.azure.com. For VNet-integrated (private access) servers, the zone name is {name}.mysql.database.azure.com (not privatelink.*). Referenced via properties.network.privateDnsZoneResourceId.
Private Endpoint
Paired WithConstraint
SubnetThe subnet must not have NSG rules that block private endpoint traffic. Subnet must have privateEndpointNetworkPolicies set to Disabled (default) for network policies to be bypassed.
Private DNS ZoneCreate a Microsoft.Network/privateDnsZones/virtualNetworkLinks to link the DNS zone to the VNet. Create an A record or use a private DNS zone group to auto-register DNS.
Private DNS Zone GroupUse privateEndpoint/privateDnsZoneGroups child resource to auto-register DNS records in the Private DNS Zone.
Key VaultGroup ID: vault. DNS zone: privatelink.vaultcore.azure.net.
Storage AccountGroup IDs: blob, file, queue, table, web, dfs. Each requires its own PE and DNS zone.
SQL ServerGroup ID: sqlServer. DNS zone: privatelink.database.windows.net.
Container RegistryGroup ID: registry. DNS zone: privatelink.azurecr.io.
