This puzzle was created for a ruleless challenge. Part of the intended puzzle is to examine the given grid and figure out what you are meant to do. For completion, I have included the rules in the comment section.
Solution code: Enter row 1 followed by row 9 (18 digits, no spaces)

Love both the concept of the cages themselves, and the "deduce the clue" idea. Really fun puzzle.

Lovely! I don't think you need to have that comment there, the puzzle is obvious enough. :)

Spoiler rule: The cage in the top left of each box contains the sum for the other killer cage in that box, when read as a two digit number. For example, the [2 4] in box 6 is indicating that the other cage adds to 24 (7+8+9)
