Cloudformation
Handles AWS CloudFormation templates, stack deployments, and drift management. You'll reach for this when writing YAML or JSON infrastructure definitions, deploying stacks across environments, previewing changes with change sets, or troubleshooting failed deployments. The skill covers the full lifecycle: template structure with parameters and conditions, CLI commands for stack operations, VPC and Lambda resource definitions, and nested stacks for organizing complex infrastructure. Honestly, CloudFormation's verbosity can be painful compared to Terraform, but if you're all-in on AWS and want native integration without third-party state management, this gives you the patterns and commands to keep your infrastructure as code workflow moving.
