AutoGineer summary
Written by AutoGineer from the skill’s own files, not by the author
This skill provides a standardized workflow for provisioning a production-grade VPC on AWS. It automates the creation of essential networking components, including public and private subnets across multiple Availability Zones, internet gateways, NAT gateways, and security groups. The process adheres to AWS Well-Architected principles, ensuring DNS support is enabled and CIDR blocks are managed effectively. It includes validation steps to ensure regional availability and provides guidance on secure access configurations.
What it does
- Validates AWS region availability and retrieves zone information.
- Creates and configures a VPC with DNS hostnames and resolution enabled.
- Provisions an Internet Gateway and attaches it to the VPC.
- Sets up NAT Gateways for high-availability outbound traffic.
- Configures route tables for public and private subnet traffic flow.
- Applies tiered security groups with configurable access controls.
When to use it
- When you need to deploy a new, production-ready VPC from scratch.
- When you require a multi-AZ network architecture for high availability.
- When you need to ensure your VPC follows AWS Well-Architected networking standards.
- When you need automated CIDR planning and consistent resource tagging.
Advantages
- Ensures consistent, repeatable infrastructure deployment.
- Reduces manual configuration errors in complex networking setups.
- Promotes high availability by distributing subnets across multiple zones.
- Enforces security best practices through tiered security group management.
Usage examples
- “Create a production VPC named my-app-vpc in us-east-1 with 3 AZs.”
- The agent will validate the region, create the VPC, enable DNS, and provision the required subnets, gateways, and security groups across 3 AZs.
- “Set up a new VPC for staging with SSH access enabled.”
- The agent will execute the workflow with the 'staging' environment tag and configure the security groups to allow SSH access based on the provided CIDR.

Creating a Production-Ready VPC Across Multiple Availability Zones
Overview
Domain expertise for creating production-ready VPC infrastructure distributed across multiple Availability Zones. Covers VPC creation with DNS support, public and private subnet layout with automatic CIDR calculation, internet gateway, NAT gateways for high-availability outbound access, route table configuration, and tiered security groups following AWS Well-Architected principles.
Create a production VPC
To create a fully configured multi-AZ VPC with public/private subnets, NAT gateways, route tables, and security groups, follow the procedure exactly. See Production VPC creation procedure.
Key parameters:
vpc_name(required): Name prefix for all resourcesregion(required): Target AWS regionallowed_web_cidrs(required): CIDR blocks allowed for web access — allow 0.0.0.0/0 only if explicitly requestedvpc_cidr(optional, default10.0.0.0/16): VPC CIDR blockavailability_zones(optional, default 3): Number of AZs (2–6)environment(required): Environment tagenable_ssh_access(optional, default false): Whether to create SSH security group
Troubleshooting
Insufficient Availability Zones
The target region must have at least 2 available AZs. Use aws ec2 describe-availability-zones to verify.
NAT Gateway creation delays
NAT Gateways can take several minutes to become available. The procedure waits for availability before configuring route tables.
Security group CIDR warnings
The procedure warns about 0.0.0.0/0 for web access CIDRs and recommends specific IP ranges for production workloads, but allows it if explicitly requested.
