Animation Principles
by iart-ai · 3K installs
The skill
The animation principles skill decides how things should move: timing, easing curves, stagger, weight and rhythm, returning concrete durations, cubic-bezier values and spring settings, for designers and motion developers.
Only when you ask.
The habit
Motion never feels stiff again.

When does it start? How does it check its work? What does it remember?
Stops after one animation change per run and one critic retry.
Your agent names the emotional intent, the micro-story and the craft goal first.
It confirms primary, secondary and ambient motion each have a role.
Enters ease out, exits ease in, moves ease in and out.
Durations follow the element type and grow with distance and size.
Groups stagger by 40-80ms for lists and 20-40ms for dense grids.
It names the failure, such as stiff or floaty, and gives exact new values.
It writes only in its own folder and asks you before anything goes out.
Read both lists. If the left one sounds like you, the Animation Principles skill helps.
No. It is tool-agnostic and returns numbers any implementation can use.
For interactive, interruptible motion; duration and easing suit timeline-locked sequences.
Copy the prompt at the top into your agent. It installs the skill from iart-ai/motion-design-skills and sets up the habit. Or run npx skills add iart-ai/motion-design-skills --skill animation-principles.
Yes. It is published under MIT. Habit is free too.
