Firstly, I didn't say "read the manual", I said "read the links I shared". And that's a pretty reasonable comment to make given I took the time to find examples knowing that I couldn't easily type them out on my phone. And if you bothered to open the links you'd realize they were brief and to the point. I was actually trying to be helpful.

Secondly, your "receipts" were incorrect. Neither of your examples follows the examples I cited, and your second example creates a key named "Description:>-", which is clearly wrong. Hence why ">-" needs to be after the colon.

Here is more examples and evidence of how to use >- and why your "receipts" were also incorrect:

Here you can clearly see my example:

    Foo: >-
      hello
      world

produces:

    { "Foo": "hello world" }

which is correct.

Whereas your example:

    Bar:>-:
      hello
      world

produces

    { "Bar:\u003e-": "hello world" }

which is incorrect.

One final point: I don't understand why you're being so argumentative here. I posted a lesser-known YAML feature in case it helps some people and you've turned it into some kind of pissing match based on bad-faith interpretations of my comments. There was no need for you to do that.
