95 / 100 · Low risk

Fine to try.

By cxcscmu/SkillLearnBench (GitHub) · media · 93 stars · scanned at commit 726e1f7

Converts an MP4 video file into individual keyframe PNG images. Use this to decompose a video into analyzable still frames. Extracts one keyframe per scene and stores them in the root directory with sequential naming.

Works with any agent that supports SKILL.md skills.

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/'extract-video-keyframes-to-png' ] || [ -L ~/.agents/skills/'extract-video-keyframes-to-png' ]; then echo 'A skill folder named extract-video-keyframes-to-png already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/cxcscmu/SkillLearnBench' "$d" && git -C "$d" checkout --quiet '726e1f79b96b0cb3d729d0e55a1c847e0b5353ae' -- 'skills/b3-teacher-feedback-claude-haiku-4-5/video-object-counting/run3_Extract-Video-Keyframes-to-PNG' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/b3-teacher-feedback-claude-haiku-4-5/video-object-counting/run3_Extract-Video-Keyframes-to-PNG' ~/.agents/skills/'extract-video-keyframes-to-png' && 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/'extract-video-keyframes-to-png' ~/.claude/skills/'extract-video-keyframes-to-png' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
