This is a DEBUT for a new clue type which I have coined as Skyscraper Thermos.

-Standard Sudoku rules apply
-Killer Cages: Digits in black cages must sum to the number in the top left corner of the cage. Digits may not repeat within a cage.
-Skyscraper Thermos: each cell is the height of a building. the cell in a circle looks along the line and counts how many buildings it can see. tall buildings hide smaller ones behind them. each line works independently from others when counting to a circles sum(e.g r3c9 has a max value of 2, not 4). Digits may repeat along a line if allowed by other rules.
-Look-and-say-cages: For Red Cages, read the clue out loud, doing this describes the nature of the cage. E.g. 1522 says there is “one five and two two(s)” in the cage.
-German Whispers: Adjacent digits on a green line must have a difference of at least 5.
