AWS CloudFormation infrastructure as code for stack management. Use when writing templates, deploying stacks, managing drift, troubleshooting deployments, or organizing infrastructure with nested stacks.
npx skills add itsmostafa/aws-agent-skills --skill cloudformation --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# AWS CloudFormation AWS CloudFormation provisions and manages AWS resources using templates. Define infrastructure as code, version control it, and deploy consistently across environments. ## Table of Contents - [Core Concepts](#core-concepts) - [Common Patterns](#common-patterns) - [CLI Reference](#cli-reference) - [Best Practices](#best-practices) - [Troubleshooting](#troubleshooting) - [References](#references) ## Core Concepts ### Templates JSON or YAML files defining AWS resources. Key sections: - **Parameters**: Input values - **Mappings**: Static lookup tables - **Conditions**: Conditional resource creation - **Resources**: AWS resources (required) - **Outputs**: Return values ### Stacks Collection of resources managed as a single unit. Created from templates. ### Change Sets Preview changes before executing updates. ### Stack Sets Deploy stacks across multiple accounts and regions. ## Common Patterns ### Basic Template Structure ```yaml AWSTemplateFormatVersion: '2010-09-09' Description: My infrastructure template Parameters: Environment: Type: String AllowedValues: [dev, staging, prod] Default: dev Mappings: EnvironmentConfig: dev: InstanceType: t3.micro prod: InstanceTyp

What does the cloudformation skill do?
AWS CloudFormation infrastructure as code for stack management. Use when writing templates, deploying stacks, managing drift, troubleshooting deployments, or organizing infrastructure with nested stacks.
How do I install it?
Run `npx skills add itsmostafa/aws-agent-skills --skill cloudformation --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From itsmostafa/aws-agent-skills, a repository with 1,139 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
