Rules
Normal sudoku rules apply.
The digits X and Y in a cage (reading left to right or top to bottom) indicate that the digit in row X column Y is equal to X+Y.
Each cage indexes a different cell.
Solution code: Column 5

I remembered watching Simon solve "Coordinate Arrows" by Piatato which featured similar logic (using arrows instead of cages), so I found it quite easy. Very enjoyable nonetheless!

Hmm, I remember having solved some similar indexing puzzles here where instead of cages there were arrows ( the shaft indexed row and the tip the column, being the sum of shaft and row the number that had to be placed). I suppose knowing the logic helped me a lot. 2.5 stars for me

Smooth start, just a little trickier finding what to look for in the midgame. Had a great time, thanks!

Beautiful!!! A bit of counting a bit of sudoku!

The highest quality puzzle! :-)

Out oft curiosity: This puzzle seems to be inspired by "Signposts" Form NotVeryNeat, right?

ND: It is funny that you say that, because I solved it last week (when it was featured on Artisanal Sudoku), but I had set this puzzle last month or so.
But the logic is really similar indeed.
Also, like amirs pointed out, this is not really a novel idea (from NotVeryNeat or me), look at the puzzle Coordinate Arrows from Piatato featured 3 years ago on CtC. This is probably what inspired me at first.

Thank you very much for creating and sharing one of the best indexing puzzles I’ve ever seen and solved. Amazing!

Lovely coordinate arrows puzzle!

For the first 10 minutes I've been convinced that this couldn't solve. But once you get a grip of the beautiful logic it just flows. Fantastic ruleset and setting, thanks a lot for sharing!
