Install
Works with every agent the skills CLI supports.
npx skills add https://github.com/dylantarre/animation-principles --skill continuous-loops- 01
Install
Run the command in your project. The CLI asks which agents to install for.
- 02
Describe the task
Ask your agent for something this skill covers. It loads continuous-loops automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.

Continuous Loop Animations
Apply Disney's 12 principles to animations that never stop.
Principle Application
Squash & Stretch: Subtle scale oscillation (0.98-1.02) creates organic breathing. Avoid rigid mechanical loops.
Anticipation: Build anticipation into the loop cycle. Brief pause at extremes before reversing.
Staging: Loops should support, not dominate. Keep amplitude subtle for background elements.
Straight Ahead vs Pose-to-Pose: Design keyframe poses that loop seamlessly. End frame must flow into start frame.
Follow Through & Overlapping: Multi-part loops have elements at different phases. Three dots pulse with 120° phase offset.
Slow In/Slow Out: Use ease-in-out for smooth oscillations. Linear motion looks mechanical.
Arcs: Circular motion follows true arcs. Spinners rotate, pendulums swing, orbits circle.
Secondary Action: Primary rotation + secondary wobble. Spinner spins while slightly bouncing.
Timing:
- Fast loops: 500-800ms (spinners, urgent indicators)
- Medium loops: 1000-2000ms (pulsing, breathing)
- Slow loops: 2000-4000ms (ambient, background)
Exaggeration: Minimal for loops - they're already attention-grabbing through repetition.
Solid Drawing: Loops must be seamless. Any jump between end and start destroys the illusion.
Appeal: Loops should be hypnotic, not annoying. Test at 30 seconds - still pleasant?
Timing Recommendations
| Loop Type | Duration | Easing | Iterations |
|---|---|---|---|
| Spinner | 600-800ms | linear (rotation) | infinite |
| Pulse | 1500-2000ms | ease-in-out | infinite |
| Skeleton Shimmer | 1500ms | ease-in-out | infinite |
| Typing Dots | 1400ms | ease-in-out | infinite |
| Breathing | 3000-4000ms | ease-in-out | infinite |
| Floating | 3000-5000ms | ease-in-out | infinite |
Implementation Patterns
/* Smooth spinner */
.spinner {
animation: spin 700ms linear infinite;
}
@keyframes spin {
to { transform: rotate(360deg); }
}
/* Organic pulse */
.pulse {
animation: pulse 2000ms ease-in-out infinite;
}
@keyframes pulse {
0%, 100% { transform: scale(1); opacity: 1; }
50% { transform: scale(1.05); opacity: 0.8; }
}
/* Staggered dots */
.dot {
animation: bounce 1400ms ease-in-out infinite;
}
.dot:nth-child(2) { animation-delay: 160ms; }
.dot:nth-child(3) { animation-delay: 320ms; }
Performance Rules
- Use
transformandopacityonly - no layout properties - Add
will-change: transformfor loops over 1 second - Pause off-screen loops with Intersection Observer
- Respect
prefers-reduced-motion- reduce or stop loops
Seamless Loop Formula
For breathing/pulsing: 0%, 100% keyframes must be identical. Use alternate direction for simpler ping-pong effects.
FAQ
What does the continuous-loops skill do?
Use when creating ongoing animations - loading spinners, pulsing indicators, ambient motion, background effects, or any animation that repeats indefinitely.
How do I install continuous-loops?
Run npx skills add https://github.com/dylantarre/animation-principles --skill continuous-loops in your project. The skills CLI detects the agents you use and copies the skill into the right folder. For Claude Code you can also place the skill folder at ~/.claude/skills/continuous-loops/ (personal) or .claude/skills/continuous-loops/ (project).
Which AI agents can use continuous-loops?
Any agent that supports the open Agent Skills format (a folder with a SKILL.md file), including Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, Windsurf, Cline, OpenCode and more.
Is continuous-loops safe to install?
No partner security audit is available yet. Skills can run commands and scripts, so read the SKILL.md and any bundled files before installing.
