Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

Turn a talking-head video and its transcript into motion-graphic B-roll timed to the speaker's words, in a continuous one-shape style (one element that morphs and never cuts, driven by a cursor, spring motion). Use when someone gives a video (and ideally a transcript) and asks for motion graphics, B-roll, animated cutaways or overlays.

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/'motion-broll' ] || [ -L ~/.agents/skills/'motion-broll' ]; then echo 'A skill folder named motion-broll already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/wolfenazz/YzPzCode' "$d" && git -C "$d" checkout --quiet 'fe7a0b72ceba504d58f83a654d92c5dc8269a7b8' -- '.agents/skills/motion-broll' && mkdir -p ~/.agents/skills && cp -R "$d"/'.agents/skills/motion-broll' ~/.agents/skills/'motion-broll' && 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/'motion-broll' ~/.claude/skills/'motion-broll' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
