A free Claude skill that measures your PDP at mobile width and gives you 5 to 10 testable hypotheses. Every number in the output is something it actually measured. If it cannot measure something, it says so.

For the full measurement it needs Claude to be able to open a browser. Without that it still works, but it can read structure only and cannot give you pixel positions. It will tell you which of the two it did.
