Motion design pass — adds purposeful animations or removes excessive ones, respecting MOTION_INTENSITY 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.

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:
references/stack.md. Use the matching section (Motion, GSAP, or Three.js). Never mix libraries on the same property.@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).

Amplify personality — raises layout variance and motion, strengthens typography and one signature detail, without slop.

Invoke when the user asks for bolder on their UI, or mentions 'bolder' alongside design / UI / frontend work.

Color strategy pass — introduces a single accent at 3-5 intentional placements, or reduces an over-colored UI back to 90% neutral.

Invoke when the user asks for colorize on their UI, or mentions 'colorize' alongside design / UI / frontend work.
