What problem does it solve? Teams often default to familiar libraries when building motion, 3D, shader, or audio-driven experiences, which can lead to over-engineered stacks or missed capabilities. This Skill replaces guesswork with a structured research process that maps a creative concept to technical capabilities and selects the smallest stack that preserves the intended experience. ## Core Features & Use Cases - Capability Mapping: Translates a creative concept into concrete technical requirements such as scroll coupling, vector state machines, real 3D, shader distortion, physics, or audio sync. - Stack Comparison: Evaluates 2-4 candidate approaches across visual ceiling, complexity, bundle cost, mobile support, accessibility, ecosystem maturity, licensing, and maintenance risk. - Use Case: Before building a product landing page with cinematic scroll choreography, use this Skill to compare GSAP ScrollTrigger, Rive, and Three.js options and receive one recommended stack with documented reasons for rejecting the alternatives. ## Quick Start Research the best current tools and libraries for building my interactive 3D product showcase and recommend a stack with alternatives.
