If you have to deal with tools that need to be configured with yaml, give https://rcl-lang.org/ https://rcl-lang.org/ a try! It can be "coded" to avoid duplication, with real variables, functions, and loops. It can show you the result that it evaluates to. It can do debug tracing, and it has a built-in build command to generate files like GitHub Actions workflows from an RCL file.
