Score: 7.3/10 (Innovation: 7, Technical: 7, Documentation: 8, Utility: 7)

Motion-contact-sheet solves the problem of coding agents being blind to UI animations by capturing timed screenshot bursts and tiling them into a single labeled contact sheet that vision-capable agents can analyze. It intelligently handles CSS, WAAPI, and GSAP animations with adaptive frame sampling, making it a novel tool for debugging motion-related visual bugs in automated workflows.

Target audience: frontend devs, ux engineers
