Kinetic sand shaping video generation

Imagine: a blade eases into a bright yellow kinetic sand block—the cross-section opens from the center, grain friction and a perfect cut. Soft yet orderly satisfaction is what this skill is for.

Core beats:

• Clean slice: Sharp kerf, even color in the face, grain texture readable
• Mold release: Castle / star / geometry lifts out, edges crisp
• Layered collapse: Colored strata slip at the edge like a soft solid in slow motion
• Streaming pour: Sand falls evenly; pile-up feels fluffy and fine

Dependencies: scripts/video_gen.js in this directory + WERYAI_API_KEY + Node.js 18+. No dependency on other Cursor skills.

Prerequisites

• WERYAI_API_KEY must be set in the environment before running video_gen.js.
• Node.js 18+ is required. Image inputs must be public https URLs (no local file paths).
• Each successful wait run consumes WeryAI credits; re-running creates new paid tasks.
