Skills that change how generated interfaces, decks and visuals actually look.
Anthropic / frontend-design
The most reached for skill in the official set, because the default aesthetic is the most visible failure.
Anthropic / canvas-design
Layout for things that are looked at rather than clicked.
Anthropic / brand-guidelines
By giving it the brand once, in a form it reloads on every task.
Anthropic / theme-factory
Generate the theme once, then apply it, instead of describing the style ten times.
Anthropic / algorithmic-art
Yes, and the seed is the part that matters.
