Cloudformation

The CloudFormation skill enables AI agents to programmatically provision, update, and delete AWS infrastructure using Infrastructure as Code templates. It automates the deployment of resources like EC2 instances, S3 buckets, and VPCs by translating high-level requirements into executable JSON or YAML definitions.

When to use it

• Rapid Provisioning: Spin up complete environments (e.g., dev/staging) from a single template without manual console clicks.
• Consistency & Compliance: Enforce standardized resource configurations across multiple AWS accounts or regions to prevent drift.
• Disaster Recovery: Quickly recreate critical infrastructure states after an outage by re-applying saved templates.
• CI/CD Integration: Automate infrastructure changes as part of a deployment pipeline triggered by code commits.

Key capabilities

• Parse and execute CloudFormation JSON and YAML templates.
• Manage resource stacks (create, update, delete).
• Handle stack outputs to retrieve post-provisioning data (e.g., public IPs).
• Validate template syntax before execution.

Example prompts

• "Create a new AWS CloudFormation stack in us-east-1 with an S3 bucket and a private EC2 instance running Ubuntu."
• "Update the existing 'production-vpc' stack to increase the subnet size from /24 to /20."
• "Delete all stacks associated with the keyword 'dev-environment' to clean up unused resources."

Tips & gotchas

Ensure your AWS credentials have cloudformation:CreateStack and related permissions before running provisioning tasks. Always review generated templates in a sandbox environment first, as incorrect parameters can lead to unintended resource costs or security gaps.
