How it works
YAML Validator detects syntax and indentation errors common in infrastructure and CI/CD files. It helps catch invalid manifests before deployment pipelines fail. Combine it with platform-specific schema checks for production confidence.

FAQ
Why does valid YAML still fail in Kubernetes?
YAML can be syntactically valid but still violate Kubernetes resource schema requirements.
What indentation rule should teams standardize?
Use spaces consistently (commonly 2) and never mix tabs to avoid parser inconsistencies.
