Make the "same prompt, two models" comparison video that every model launch produces (Claude Fable 5.2 vs Opus 5.5, Seedance vs Kling, Eevee vs Cycles): run one prompt twice under the same rules, log the real time and cost of each run, then lay the two results side by side (1920×1080) or stacked (1080×1920), started on the same frame, each with its name and its time and cost under it, optionally blind ("A" and "B" until the last seconds, then the reveal) and with a winner frame. scripts/split.p…

What this skill can do

Install

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

if [ -e ~/.agents/skills/'model-split-screen' ] || [ -L ~/.agents/skills/'model-split-screen' ]; then echo 'A skill folder named model-split-screen 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 "$d" checkout --quiet '40706766fd37c03ca624f5206741fef55dd2a684' -- 'plugins/vargHQ/skills/model-split-screen' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/vargHQ/skills/model-split-screen' ~/.agents/skills/'model-split-screen' && 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/'model-split-screen' ~/.claude/skills/'model-split-screen' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
