eternityspring/reelbench-skills
Skills for studying finished videos: one breaks a video into a shot-by-shot table with measured durations, another renders it with the current shot's data beside the picture.
video-shots takes a finished video, gets cut points, durations and motion from ffmpeg scene detection, and has the model judge only shot size, category, camera move and frame content from contact sheets; 15 scripted quality gates check the result. It writes shots.json, a Markdown shot table and a single offline HTML report with a synced player and a filterable table. video-sync then takes that data and the source video and renders a copy with the current shot's details beside the picture, choosing the layout from the aspect ratio; a third skill, video-scrub, rebuilds a video without its metadata. Everything needs only node and ffmpeg (video-sync also needs a Chrome-family browser) and no API keys, which suits breaking down reference films or AI shorts for pacing and shot language.
Included skills
01From the README
The install command quoted from the repository README.
git clone https://github.com/eternityspring/reelbench-skills.git
cd reelbench-skills
./scripts/install.sh02skills CLI, for Claude Code, Codex and others
The open skills CLI from Vercel Labs installs a skill from a GitHub repo into the folder each agent expects. It asks which skills and which agents you want, and it installs for the current project unless you add the -g flag, which installs for your user account. Add --list to see what a repo contains before you install anything.
npx skills add eternityspring/reelbench-skills03Claude Code, skills folder
Copy the skill's folder, the one that holds SKILL.md, into ~/.claude/skills/ to use it in every project on your machine, or into .claude/skills/ in a repository to use it there and share it by committing it. Claude Code picks up changes to these folders during a session. If the folder did not exist when the session started, run /reload-skills.
04Claude Code, plugin marketplace
Some repos publish a plugin marketplace, a .claude-plugin/marketplace.json file. Add it in Claude Code, then install a plugin from it with /plugin install plugin-name@marketplace-name. Plugins can bundle hooks and MCP servers along with skills, so read the details panel before you confirm.
/plugin marketplace add eternityspring/reelbench-skills05Codex, skills folder or $skill-installer
Codex reads skills from .agents/skills in your working folder and its parent folders up to the repository root, and from $HOME/.agents/skills for every repository. Copy the skill's folder into one of them, or run $skill-installer inside Codex and ask it to install from the repo. Codex detects new skills automatically and needs a restart only if one does not appear.
The first command is quoted from the author's README. The others are the standard ways to install a skill from a GitHub repository. They are templates and may not apply here, for example if the repo has no plugin marketplace, so follow the README first.
