Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install web-animation-principles

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent writes or reviews animations against 58 rules: easing curves, durations, animated properties, interruptible gestures and accessibility. It draws on Emil Kowalski's practice for toasts, drawers and transitions. You get smoother motion that fits the context.
