Creates simple Three.js web apps with scene setup, lighting, geometries, materials, animations, and responsive rendering. Use for: "Create a threejs scene/app/showcase" or when user wants 3D web content. Supports ES modules, modern Three.js r150+ APIs.
Design and implement microinteractions, motion design, transitions, and user feedback patterns. Use when adding polish to UI interactions, implementing loading states, creating gesture-based interactions, designing hover/focus states, building notification/toast systems, adding scroll-triggered animations, implementing drag-and-drop, or creating delightful user experiences.
Create a new technique plugin for a technology (language, tool, framework, or validation)
A simple example skill that demonstrates the basic structure and functionality. Use when you need to show how skills work or test skill loading.
This skill encodes Emil Kowalski's philosophy on UI polish, component design, animation decisions, and the invisible details that make software feel great.
Socratic questioning protocol + user communication. MANDATORY for complex requests, new features, or unclear requirements. Includes progress reporting and error handling.
Multiplayer game development principles. Architecture, networking, synchronization.
Game development orchestrator. Routes to platform-specific skills based on project needs.
Game audio principles. Sound design, music integration, adaptive audio systems.
Game design principles. GDD structure, balancing, player psychology, progression.
Mobile game development principles. Touch input, battery, performance, app stores.
Use when generating animated game sprites, creating sprite sheets, building character animations for 2D games, or needing consistent multi-frame pixel art from AI image generation models
Create new custom skills by writing SKILL.md playbooks
Interactive skill for creating new Bases Views. Guides through adaptive questioning, then generates all necessary files.
Create and manage sprite animations with multiple frames, animation tags, frame durations, and linked cels. Use when the user wants to animate a sprite, add animation, create movement, make it move, mentions "animation", "animated", "frames", "keyframes", "frame rate", "FPS", "timing", "duration", "walk cycle", "run cycle", "idle animation", "attack animation", "jump", "movement", "motion", or describes actions like "walking", "running", "jumping", "attacking", "breathing", "bobbing", "bouncing". Trigger on animation tags, loops, playback, sequences, "add frames", "duplicate frame", "frame timing", "ping-pong", "loop", "sequence". Also for linked cels, static backgrounds, and frame optimization.
Export sprites to PNG, GIF, or spritesheet formats with JSON metadata for game engines. Use when the user wants to "export", "save", "output", "render", "generate", "create file", mentions file formats like "PNG", "GIF", "animated GIF", "spritesheet", "sprite sheet", "texture atlas", "tile sheet", or game engine integration with "Unity", "Godot", "Phaser", "Unreal", "GameMaker". Trigger on layout terms ("horizontal", "vertical", "grid", "packed", "strip"), scaling ("2x", "4x", "upscale", "pixel-perfect"), file operations ("save as", "export to", "output to"), metadata formats ("JSON", "XML", "metadata", "atlas data"), and delivery terms ("for web", "for game", "for Twitter", "for itch.io", "optimized").
Generate 3D animation scripts and lay explanations for drug mechanisms.
