Turn a browser game or three.js / WebGL scene an agent built into a cinematic trailer MP4: a virtual clock injected before the page's scripts makes every frame exact at 30 or 60 fps, a director JSON scripts each shot (key and mouse inputs, game setup, trailer camera paths, slow motion, HTML titles and end cards), headless Chrome captures 1920x1080 frames, ffmpeg cuts them on the beat, a music bed (code-written or from varg) is normalised to -14 LUFS, and a checker measures frozen frames, loudne…

Works with any agent that supports SKILL.md skills.

Safer alternatives

Low-risk skills in the same category (coding) that look related. Check that one does what you need.

Install

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

if [ -e ~/.agents/skills/'code-game-trailer' ] || [ -L ~/.agents/skills/'code-game-trailer' ]; then echo 'A skill folder named code-game-trailer already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/hashgraph-online/awesome-codex-plugins' "$d" && git -C "$d" checkout --quiet '6d2e63f73f845eb5dd94c1debba627d4b6e32fba' -- 'plugins/vargHQ/skills/code-game-trailer' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/vargHQ/skills/code-game-trailer' ~/.agents/skills/'code-game-trailer' && 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-game-trailer' ~/.claude/skills/'code-game-trailer' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
