Generate crafted SVG/CSS components, props, characters, and environments for animated explainer videos — the build order, light rules, factory patterns, and engineering contracts that make assets read as illustrated objects AND survive choreography. Use when creating or upgrading any visual asset: a prop, mascot, component system, or background world.

The guided end-to-end path for building an animated explainer video from zero — walks you phase by phase (script → assets → choreography → retention → gates → voiceover → publish), telling you which skill and tool to use at each step and what "done" means before advancing. Use when starting a new explainer video, when unsure what to do next mid-build, or when someone asks to be guided through the process.

Build a Kurzgesagt-quality GSAP-powered animated explainer video — a self-contained HTML file that plays like a produced YouTube video: layered worlds, character populations, physics-feeling choreography, a flying host mascot, seekable player chrome. Use when the user wants a high-production explainer/YouTube video, a "GSAP video", or a step up from a CSS-only animated explainer.

Run a 3-round YouTube-retention optimization pass on an animated explainer video (GSAP or CSS-only harness) — audit the hook/peak loop, kill dead zones, align scene length to choreography, add late B-beats, then verify with freeze-frames. Use when the user wants a video "optimized for retention", a "retention pass", or before publishing/recording VO for any explainer.
