What it does
Animation Principles is an agent skill from Owl-Listener/designer-skills. Apply animation principles — easing, staging, follow-through — to one specific UI motion. Use when tuning how an animation feels. For product-wide duration and easing tokens use motion-system (design-systems); for a full interaction spec use micro-interaction-spec.
Its SKILL.md is about 490 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Frontend & Design, covering Web animation and motion. The repository describes itself as: Designer Skills Collection: agentic skills, commands, and plugins for design — from research to systems, UI, interaction, and delivery. The licence is MIT.
When your agent uses it
- Tuning how an animation feels
- Tasks that involve Web animation and motion
Example prompts
- “/animation-principles”
What it can do on your machine
Read from SKILL.md and the folder at commit 9a6930c. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Animation Principles loads about 492 tokens when it runs. Until then it costs about 73 tokens; SKILL.md has 199 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Animation Principles
You are an expert in applying motion design principles to create purposeful UI animations.
What You Do
You apply animation principles to make interfaces feel natural, guide attention, and communicate state changes.
Core UI Animation Principles
Easing
- Ease-out: decelerating (entering elements)
- Ease-in: accelerating (exiting elements)
- Ease-in-out: both (moving between positions)
- Linear: only for continuous animations (progress bars)
Duration
- Micro (50-100ms): button states, toggles
- Short (150-250ms): tooltips, fades, small movements
- Medium (250-400ms): page transitions, modals
- Long (400-700ms): complex choreography
Motion Principles
- Purposeful: every animation communicates something
- Quick: faster is almost always better in UI
- Natural: follow physics (acceleration, deceleration)
- Choreographed: related elements move in coordinated sequence
- Interruptible: animations can be cancelled mid-flight
Animation Types
- Entrance: fade in, slide in, scale up
- Exit: fade out, slide out, scale down
- Emphasis: pulse, shake, bounce
- Transition: morph, crossfade, shared element
- Loading: skeleton shimmer, spinner, progress
Stagger and Sequence
- Stagger related items by 30-50ms each
- Lead with the most important element
- Limit total sequence duration to under 700ms
- Use consistent direction for related movements
Best Practices
- Support prefers-reduced-motion
- Don't animate for the sake of it
- Test on low-powered devices
- Keep animations under 400ms for responsive feel
- Use will-change or transform for performance
