Individual skill
aws-cloudformation
Authors, validates, and troubleshoots AWS CloudFormation templates. Covers template authoring with secure defaults, local validation with either cfn-lint or cloudformation-validate, cfn-guard security and compliance checks as a recommended default, account-aware CloudFormation service pre-deployment validation, CloudFormation Express mode for faster deployments, and root-cause diagnosis of failed stacks using CloudFormation events and CloudTrail correlation. Also covers author-time template intelligence with the CloudFormation Language Server and published cloudformation-validate libraries.

# CloudFormation
## Overview
Domain expertise for the full CloudFormation lifecycle: authoring templates, validating them before deployment, and diagnosing failures after deployment. Works with plain CloudFormation (YAML/JSON). For CDK, use a CDK-focused skill if available.
