Sorry I don't remember. My son explained it to me a couple of years ago. Must be on the internet somewhere.

Use of the word "spiral" is unhelpful

Could be another kata...?

Yeah. To confuse the devil.

Ok

Fixed, thanks.

Fixed, thanks.

Ok, fixed. Thanks.

The random tests call your compose function 100 times. As with the example tests, there are multiple assertions which check the validity of the string returned by your code

I think an example would be too much of a spoiler

Whatabout to disallow the text "builtins" in the solution?

I have updated the description to describe the restrictions implemented in the tests.

Hopefully that will suffice, but I can republish if it's really necessary

Ok, I have made adjustments. Thanks.
