What are common YAML syntax errors?

Common errors include inconsistent indentation (YAML requires spaces, not tabs), missing colons, improper list formatting, and unquoted strings containing special characters.

Can I use this for Kubernetes configs?

Yes, the validator works perfectly for Kubernetes YAML files. It checks syntax but not Kubernetes-specific schema requirements (use kubectl for that).
