animate
Motion design pass — adds purposeful animations or removes excessive ones, respecting MOTIONINTENSITY and the project's animation stack. Use when the user asks to add animation, "make it feel smoother", fix janky transitions, or trim motion that's distracting. Invoke when the user asks for animate on their UI, or mentions 'animate' alongside design / UI / frontend work.

Install
Works with every agent the skills CLI supports.
npx skills add https://github.com/educlopez/ui-craft --skill animate- 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 animate automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.
SKILL.md
The instructions your agent reads when the skill is triggered.
Context: this sub-skill is one lens of the broader ui-craft skill. If the ui-craft skill is also installed, read its SKILL.md first for Discovery + Anti-Slop + Craft Test, then apply the specific lens below.
Add or fix animations in $ARGUMENTS. Load the ui-craft skill.
Step 1 — Decision Ladder: run the Decision Ladder from references/motion.md first. Anything that fails it gets removed, not improved.
Step 2 — Pick the library:
- If user opted into a stack during Discovery → read
references/stack.md. Use the matching section (Motion, GSAP, or Three.js). Never mix libraries on the same property. - Otherwise → CSS transitions /
@keyframes/animation-timeline: view()only.
Step 3 — Apply motion budget:
| Element | Budget |
|---|---|
| Color/opacity | 100-150ms |
| Small UI (tooltips, dropdowns) | 150-200ms |
| Medium UI (modals, panels) | 200-300ms |
| Large UI (page transitions, drawers) | 300-400ms |
Exit ≈ 75% of entrance duration (shorter, same ease-out — or a flatter tail like cubic-bezier(0.4, 0, 1, 1) for a softer exit). Never ease-in on UI (see references/motion.md). cubic-bezier(0.22, 1, 0.36, 1) is a safe spring-like default.
Step 4 — Multi-stage sequences → read ../examples/animation-storyboard.md. Stagger 30-80ms, not 200ms.
Step 5 — Respect the knobs:
MOTION_INTENSITY ≤ 3→ hover states only, no entrances, no scroll-triggered.MOTION_INTENSITY 4-7→ standard entrances + hover, one scroll reveal max per section.MOTION_INTENSITY 8+→ scroll-linked, page transitions, magnetic cursor OK (still honor reduced-motion).
Output: edit code directly. After each file, print the Review Format table. Flag any animation you removed and why.
Next step: /polish — the compound details around the motion you just added (rung 1).

All animation knowledge for HyperFrames — atomic motion rules, multi-phase scene blueprints, scene transitions, broader motion-design techniques, AND the seven runtime adapters (GSAP default, plus Lottie, Three.js, Anime.js, CSS keyframes, Web Animations API, TypeGPU). Use for any motion or animation task: pick 2-4 rules and compose, or load a blueprint, or look up runtime-specific API (e.g. GSAP eases / Lottie player / Three.js mixer). Also covers auditing an existing composition's choreography (animation map) and 24 named text-animation effects. HyperFrames-native: single paused timeline, seek-safe, deterministic.
