ArcReel/ArcReel
Skills that let an agent drive ArcReel, a self-hosted AI video workbench, from script prompts and reference sheets through storyboard stills, clips, narration and a timeline edit.
The runtime skills call ArcReel's MCP tools to write image and video prompts for scripted shots, make character, scene and prop reference sheets, render storyboard stills and grid storyboard sheets (which you review before they are sliced), generate clips in storyboard-to-video or reference-to-video mode, synthesize narration, and cut a per-episode timeline that can be exported as a Jianying draft. The video-workflow skill reads the project's workflow plan to pick the next step and asks for your consent before destructive or billable actions. Only three skills are published for outside agents, through the MIT-licensed ArcReel/skills mirror: video-workflow, setup-arcreel-skills (connects an agent to an ArcReel server) and adapt-custom-endpoint (wires in a custom polling-style image or video provider); the rest are bundled with ArcReel's own built-in agent. All of them need a running ArcReel instance, self-hosted with Docker, with model providers already configured.
Included skills
01From the README
The install command quoted from the repository README.
npx skills add ArcReel/skills02skills 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 https://github.com/ArcReel/ArcReel/tree/main/agent_runtime_profile/.claude/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 ArcReel/ArcReel05Codex, 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.
