# CloudFormation

Catch a bad template before the stack rolls back on you

## What this does

You describe your infrastructure in a template file, and either you are writing one or one has just failed on you. This helps you author it, check it before it goes out, and when a deployment does break, work back from the events to what actually caused it. Useful whether you are starting the file or staring at a failure.

### Top 3 things it does for you

- Write a template with sensible defaults already in place
- Check a template before you deploy it
- Find out why a stack deployment failed

A scan is named by the exact content it read, not by a version number. A different version is a different artifact, and nothing here applies to a version AIR has not scanned.

## About CloudFormation

Three moments with AWS CloudFormation templates: writing one, checking one, and working out why one failed. This covers all three.

On authoring, it starts from secure defaults. Before you deploy, it uses pre-deployment validation - cfn-lint, cfn-guard and change sets - to catch what would otherwise fail live. And when a stack has already failed, it diagnoses the root cause by reading CloudFormation events alongside CloudTrail.

## Questions

### Is CloudFormation safe to install?

AIR scanned this exact version of CloudFormation and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit b33847dd218c, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/aws-cloudformation.

### How do I install CloudFormation?

Open https://airmarket.ai/app/aws-cloudformation on Air Market and use the install action: Air Market hands Claude a prompt naming this exact skill, and Claude sets it up. Source, pinned to the exact commit this listing describes: https://github.com/aws/agent-toolkit-for-aws/tree/b33847dd218c6ceef176cd5efdcfff50560faf7d/skills/core-skills/aws-cloudformation. Install from that link, not the branch.
