Frequently asked questions

Why does my YAML fail to parse?

Almost always indentation — YAML is whitespace-sensitive and does not allow tabs for indentation. The error message names the line.

Is my config uploaded?

No. Parsing happens locally, which matters because CI and Kubernetes configs often contain internal hostnames.
