I've hit problems where YAML generated by one implementation will hit parsing quirks in another implementation. Now my advice is: If you have something that consumes YAML, generate JSON and feed it that instead. YAML is defined to be a superset of JSON, and every implementation should be able to handle it fine.

For those interested, the problem was with the string "08". At least at the time, the pyYAML generator I was using would render it as 08 (without quotes), which is not parsable as a number because the leading 0 indicates the number is in octal, but 8 isn't a valid octal digit. Since it wasn't parsable as a number, it should default to being treated as a string. However the golang parser disagreed and instead raised an error because "8" was not a valid octal digit.

Yeah exactly, generate json instead. I now have some GitHub Actions config in Python, and some in Nix. Nix is actually really nice for this. Like yaml it has less line noise than json and it support comments, but unlike yaml the language is extremely simple without weird corner cases to make it "easier", and it has variables and functions so you can write reusable jobs.
