Does it support both YAML and JSON templates?

While it can process both, the skill specifically recommends and prioritizes YAML for superior readability and maintainability in production environments.

How does it improve infrastructure security?

It enforces the use of pseudo-parameters over hardcoded ARNs, recommends DeletionPolicies for stateful resources, and suggests using cfn-nag for CI/CD security audits.

Can this skill help with existing CloudFormation errors?

Yes, it specializes in troubleshooting stack creation failures, resolving UPDATE_ROLLBACK_FAILED states, and identifying resource drift.

Can I use this skill for AWS CDK or Terraform?

No, this skill is specifically optimized for raw CloudFormation templates. If you are using CDK or Terraform, you should use skills tailored to those frameworks.

Infraestructura en la Nube

Optimizes AWS CloudFormation templates using production-ready patterns, nested stack architectures, and infrastructure-as-code best practices.

This skill empowers Claude to architect, write, and audit AWS CloudFormation templates with a focus on maintainability, cost-efficiency, and reliability. It provides expert guidance on implementing nested or cross-stack architectures, troubleshooting complex deployment failures, and ensuring resource safety with deletion policies. By enforcing standards like YAML preference, parameterization, and validation, it helps developers build robust infrastructure-as-code (IaC) solutions while avoiding common pitfalls like hardcoded ARNs or monolithic templates.
