Make the sound of any video so it feels real: AI voices that don't sound fake (cast from candidates a person picks, directed with each model's documented tags), dialogue and narration written for the ear with pauses, breaths and small actions, sound effects on the right frame, music planned bar by bar with a quiet part, and a measured mix. Built from 480 sourced findings (Walter Murch, Randy Thom, Ben Burtt, trailer editors, NPR, voice directors, model docs, HyperFrames, earshot) plus paid test…
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/'video-sound' ] || [ -L ~/.agents/skills/'video-sound' ]; then echo 'A skill folder named video-sound 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 "$d" checkout --quiet '3e1e6b20ffc28f42923e391f29f075c424e19e64' -- 'plugins/vargHQ/skills/video-sound' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/vargHQ/skills/video-sound' ~/.agents/skills/'video-sound' && 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/'video-sound' ~/.claude/skills/'video-sound' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
