AI-first code editor with Composer
Before installing skills in Cursor, ensure your development environment meets these requirements:
node --version12-principles-of-animationExecute the skills CLI command in your project's root directory to begin installation:
Fetches 12-principles-of-animation from raphaelsalaja/userinterface-wiki and configures it for Cursor.
The CLI shows a list of agents. Use arrow keys and space to select Cursor:
Confirm successful installation by checking the skill directory location:
Restart Cursor to activate 12-principles-of-animation. Access via /12-principles-of-animation in your agent's command palette.
We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.
Skills execute code in your environment. Always review source, verify the publisher, and test in isolation before production.

Review animation code for compliance with Disney's 12 principles adapted for web interfaces.
file:line format| Priority | Category | Prefix |
|---|---|---|
| 1 | Timing | timing- |
| 2 | Easing | easing- |
| 3 | Physics | physics- |
| 4 | Staging | staging- |
timing-under-300msUser-initiated animations must complete within 300ms.
Fail:
.button { transition: transform 400ms; }
Pass:
.button { transition: transform 200ms; }
timing-consistentSimilar elements must use identical timing values.
Fail:
.button-primary { transition: 200ms; }
.button-secondary { transition: 150ms; }
Pass:
.button-primary { transition: 200ms; }
.button-secondary { transition: 200ms; }
timing-no-entrance-context-menuContext menus should not animate on entrance (exit only).
Fail:
<motion.div initial={{ opacity: 0 }} animate={{ opacity: 1 }} />
Pass:
<motion.div exit={{ opacity: 0 }} />
easing-entrance-ease-outEntrances must use ease-out (arrive fast, settle gently).
Fail:
.modal-enter { animation-timing-function: ease-in; }
Pass:
.modal-enter { animation-timing-function: ease-out; }
easing-exit-ease-inExits must use ease-in (build momentum before departure).
Fail:
.modal-exit { animation-timing-function: ease-out; }
Pass:
.modal-exit { animation-timing-function: ease-in; }
easing-no-linear-motionLinear easing should only be used for progress indicators, not motion.
Fail:
.card { transition: transform 200ms linear; }
Pass:
.progress-bar { transition: width 100ms linear; }
easing-natural-decayUse exponential ramps, not linear, for natural decay.
Fail:
gain.gain.linearRampToValueAtTime(0, t + 0.05);
Pass:
gain.gain.exponentialRampToValueAtTime(0.001, t + 0.05);
physics-active-stateInteractive elements must have active/pressed state with scale transform.
Fail:
.button:hover { background: var(--gray-3); }
/* Missing :active state */
Pass:
.button:active { transform: scale(0.98); }
physics-subtle-deformationSquash/stretch deformation must be subtle (0.95-1.05 range).
Fail:
<motion.div whileTap={{ scale: 0.8 }} />
Pass:
<motion.div whileTap={{ scale: 0.98 }} />
physics-spring-for-overshootUse springs (not easing) when overshoot-and-settle is needed.
Fail:
<motion.div transition={{ duration: 0.3, ease: "easeOut" }} />
// When element should bounce/settle
Pass:
<motion.div transition={{ type: "spring", stiffness: 500, damping: 30 }} />
physics-no-excessive-staggerStagger delays must not exceed 50ms per item.
Fail:
transition={{ staggerChildren: 0.15 }}
Pass:
transition={{ staggerChildren: 0.03 }}
staging-one-focal-pointOnly one element should animate prominently at a time.
Fail:
// Multiple elements with competing entrance animations
<motion.div animate={{ scale: 1.1 }} />
<motion.div animate={{ scale: 1.1 }} />
staging-dim-backgroundModal/dialog backgrounds should dim to direct focus.
Fail:
.overlay { background: transparent; }
Pass:
.overlay { background: var(--black-a6); }
staging-z-index-hierarchyAnimated elements must respect z-index layering.
Fail:
.tooltip { /* No z-index, may render behind other elements */ }
Pass:
.tooltip { z-index: 50; }
When reviewing files, output findings as:
file:line - [rule-id] description of issue
Example:
components/modal/index.tsx:45 - [timing-under-300ms] Exit animation 400ms exceeds 300ms limit
components/button/styles.module.css:12 - [physics-active-state] Missing :active transform
After findings, output a summary:
| Rule | Count | Severity |
|---|---|---|
timing-under-300ms |
2 | HIGH |
physics-active-state |
3 | MEDIUM |
easing-entrance-ease-out |
1 | MEDIUM |

Steps
Common Pitfalls
✓ Do
✗ Don't
💡 Pro Tips
✓ Use when
Use when skill capabilities match your task, clear ROI on time saved, and you can validate outputs. Best for repetitive tasks, learning, and quality improvement.
✗ Avoid when
Avoid when task requires deep expertise you can't validate, involves sensitive decisions, or when learning process is more valuable than speed of completion.
