Quick brief
Use cfn-lint when an agent needs to review or gate AWS CloudFormation changes before deployment. It can validate template structure, catch invalid properties, check region-specific resource rules, and surface intrinsic-function mistakes before they become failed stack operations. The scope is tightly bounded to pre-deploy CloudFormation validation, which keeps this from collapsing into a general AWS product listing.
