Art & Design

Web animation expertise covering CSS animations and transitions, GSAP, Framer Motion, scroll-triggered animations, performance optimization, animation choreography, easing functions, reduced motion accessibility, and animation design patterns. Use when the user asks about web animation master, web animation master best practices, or needs guidance on web animation master implementation. Do NOT use when the user needs a different specialized skill or is asking about an unrelated technology domain.

Game narrative design covering branching dialogue systems, world lore construction, environmental storytelling techniques, character arc design for interactive media, player agency and consequence systems, quest narrative structure, narrative documentation, and integration with game mechanics. Use when the user asks about narrative designer or needs help with related topics. Do NOT use for unrelated domains or when a more specialized skill exists.

Comprehensive motion graphics guidance covering title design, lower thirds, animated explainers, kinetic typography, logo animation, After Effects and Apple Motion workflows, design principles for motion, storyboarding for motion, and building a motion design practice. Use when the user asks about motion graphics or needs help with related topics. Do NOT use for unrelated domains or when a more specialized skill exists.

Interactive storytelling for games covering branching narratives, dialogue trees, environmental storytelling, lore design, character writing for games, quest design, player agency, world-building for interactive media, and narrative integration with game mechanics. Use when the user asks about game narrative writer or needs help with related topics. Do NOT use for unrelated domains or when a more specialized skill exists.

Web animation expertise covering CSS animations and transitions, Web Animations API, Framer Motion, GSAP, scroll-driven animations, layout animations, spring physics, reduce-motion preferences, and performance budgets. Use when the user asks about animation designer, animation designer best practices, or needs guidance on animation designer implementation. Do NOT use when the user needs a different specialized skill or is asking about an unrelated technology domain.

SwiftUI animations, @Animatable macro, withAnimation, transitions, PhaseAnimator, KeyframeAnimator, and interactive motion design. Use when user asks about animations, transitions, @Animatable, withAnimation, spring animations, keyframes, or motion design.

Optimize 8-bit animations for smooth performance. Apply when creating animated pixel art, game UI effects, or any retro-styled animations.

Animation and micro-interaction patterns for web interfaces. Use when adding transitions, animations, hover effects, loading states, or any motion to UI components.

Add micro-interactions and animations using Framer Motion. Use when user asks about animations, transitions, hover effects, or motion design. MANDATORY for every component.

Implement fluid animations for poker gameplay and UI interactions

Guidelines for applying Disney's 12 principles of animation to web interfaces. Use when implementing motion, reviewing animation quality, or designing micro-interactions. Triggers on tasks involving CSS animations, transitions, motion libraries, or UX feedback.

Cria um script Python completo com interface gráfica (Tkinter) para dividir arquivos de áudio em segmentos, utilizando um executável FFmpeg localizado na mesma pasta do script.

Opinionated, strict animation craft guide for SwiftUI iOS 26 / Swift 6.2 apps. Contains 50 rules across 8 categories, prioritized by impact. Derived from Airbnb Engineering motion patterns, Apple WWDC sessions, and Apple Human Interface Guidelines. Mandates @Equatable on every animated view, motion tokens for all spring/timing values, and design system tokens for layout.

GSAP animation best practices for web design - scroll triggers, performance optimization, accessibility, responsive animations, and testing integration. Use when implementing or reviewing animations on WordPress or any web project.

Reanimated runs animations on the native UI thread — no JS bridge bottleneck, no dropped frames. Animations stay at 60fps even when your JavaScript thread is busy. It uses "worklets" — small JavaScript functions that execute on the UI thread via JSI. The standard for production-quality animations in React Native: gesture-driven interactions, layout transitions, scroll-based effects, and shared element transitions.

Motion design principles for mobile apps. Covers timing curves, transitions, gestures, and performance-conscious animations. (triggers: **/*_page.dart, **/*_screen.dart, **/*.swift, **/*Activity.kt, **/*Screen.tsx, Animation, AnimationController, Animated, MotionLayout, transition, gesture)

Use when implementing SwiftUI animations, understanding VectorArithmetic, using @Animatable macro, zoom transitions, UIKit/AppKit animation bridging, choosing between spring and timing curve animations, or debugging animation behavior - comprehensive animation reference from iOS 13 through iOS 26

Production-ready UI motion system for React/Next.js. Use when implementing animations, transitions, or motion patterns.

One sentence - what this skill does and when to invoke it

Reviews animation and motion code against a high craft bar derived from Emil Kowalski's design engineering philosophy. Default to flagging; approval is earned.

Reverse-lookup glossary that turns a vague description of a web animation or motion effect into its exact term ("the bouncy thing when a popover opens" → Pop in; "the iOS rubber-band scroll" → Rubber-banding). Use when the user asks "what's it called when…", or describes a motion effect without knowing its name and wants the right word to prompt an AI or designer with. For naming an effect, not designing or building one.

Inspect a Core UI or code surface for a small number of justified motion opportunities and explicitly identify what should remain static. Use when asked what should animate, where motion would improve feedback or comprehension, how to make an interface feel more alive without over-animating it, or whether a proposed animation is worth adding. Read-only; do not use to review or fix existing motion code or to implement animations.

Three.js animation - keyframe animation, skeletal animation, morph targets, animation mixing. Use when animating objects, playing GLTF animations, creating procedural motion, or blending animations.
