strict old-skill vs new-skill comparison
ui-polish · same task A, real old vs new outputs
This comparison uses one concrete task A and two real outputs produced at different times in the update wave: the old side was created before the skill update, and the new side was created after the skill update.
Method: Task A is a floating scene/appearance control panel for a persistent Ubuntu desktop utility. The old side already used suspended premium utility plus controlled levitation, but it could still collapse into a panel that felt merely calm. This update added floating-premium-diagnosis.md, which forces an explicit diagnosis of weak-floating signals — rest-pose lift, shell-to-backdrop separation, interior gravity, and interaction energy — before choosing the final treatments.
Old skill on task A
pre-floating-diagnosis
Old shaping: the shell is already cleaner and more premium than earlier waves, but it still reads as a composed dark panel first and a suspended object second. The interior rows keep enough weight that the shell does not unmistakably own the floating effect.
New skill on task A
+ premium floating diagnosis
New shaping: the shell now reads as the premium floating object first. Rest-pose lift is clearer, the backdrop separation is more explicit, the interior becomes calmer and less card-like, and the interaction layer carries a little more life without making the whole panel louder.
