Why use a YAML formatter?

YAML configuration files used in Kubernetes, Docker Compose, GitHub Actions, and Ansible can grow unruly when edited by many contributors. Mixed 2-space and 4-space indentation, inconsistent quoting of string values, and mixed block vs flow scalar styles make YAML hard to review. QuickKit's YAML formatter uses Prettier's YAML plugin to normalize indentation to 2 spaces, standardize string quoting, and reformat block sequences and mappings consistently. The result is YAML that renders correctly in any parser and is easy to diff in pull requests.
