Check before installing. Some of what it can do is expected: a media skill usually calls an AI service over the internet.

Prototype a video in code with an agent. Decides if a shot needs a 3D prototype at all and which tool fits (Three.js, Blender, a phone act-out, storyboards, Remotion, Cinema 4D, Unreal), stages geometry, people, camera and light in real metres, copies a reference video shot by shot with a solved 3D camera, stages a shot from a painting or still, invents one when there is no reference, checks everything with numbers and frames, and writes the handoff to Seedance or other video models. Same scene…

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/'code-to-video-previz' ] || [ -L ~/.agents/skills/'code-to-video-previz' ]; then echo 'A skill folder named code-to-video-previz already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/vargHQ/skills' "$d" && git -C "$d" checkout --quiet '72e8109188e3366ba8d365902a84d6b237dec1d7' -- 'code-to-video-previz' && mkdir -p ~/.agents/skills && cp -R "$d"/'code-to-video-previz' ~/.agents/skills/'code-to-video-previz' && 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/'code-to-video-previz' ~/.claude/skills/'code-to-video-previz' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
