How Opus 5.5 built a loopable motion piece: 8 min planning, 4 min autofixing — full prompt inside
techhalla · x · 2026-09-25
techhalla shares the full prompt and breakdown of the Opus 5.5 motion piece: 8 minutes planning the approach, 2 minutes installing dependencies and building the HTML, 4 minutes autofixing and rendering. The prompt is a complete "world-class motion designer" persona spec with hard constraints: exactly 20.00s, frame 0 == last frame (loopable), single HTML file, 1080×1080 at 60fps, a strict 4-color palette (near-black bg, magenta #FF2BD6, acid green #B8FF00, white), no UI gradients. A reusable template for code-driven creative generation.
