Create and revise code-driven videos with Canvas, SVG, HTML/CSS, Three.js, Remotion, Manim, or p5.js, including sound, deterministic frame capture, visual review, and MP4 verification. Use for rendered explainers, procedural animations, motion graphics, promos, and music-synchronized films; not for general web apps, scroll-driven HTML stories, or footage generation with video models.

Works with any agent that supports SKILL.md skills.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'sn-code-video' ] || [ -L ~/.agents/skills/'sn-code-video' ]; then echo 'A skill folder named sn-code-video already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/OpenSenseNova/SenseNova-Skills' "$d" && git -C "$d" checkout --quiet '004a2426fa092097d65ac9233ca0bcb2be793f57' -- 'skills/sn-code-video' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/sn-code-video' ~/.agents/skills/'sn-code-video' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'sn-code-video' ~/.claude/skills/'sn-code-video' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
