ChatCut-Inc/agent-plugin
Plugin from the ChatCut team that lets Claude Code, Codex and Cursor drive the hosted ChatCut editor, with skills for clip generation, voice and music, dubbing, captions, motion graphics and export.
Install it in Claude Code, Codex or Cursor and sign in to ChatCut, and the agent can import media into a ChatCut project and edit its timeline through ChatCut's hosted MCP server. The bundled skills cover generating clips (Seedance, Kling, MiniMax H3, Gemini Omni) and images, voice and sound effects, music, AI avatar presenters, video dubbing with optional lip sync, speech-led and multicam editing, shader transitions and color grades, motion graphics, transcription with captions, export, and a check that edits actually show up on the timeline. Everything runs in the hosted editor, so you need a ChatCut account, and the generation features need a paid plan or credits. The repo has no root LICENSE file, though the plugin manifests declare GPL-3.0-only; it also holds packages for Grok Bot and Kimi Work.
Included skills
01skills 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 ChatCut-Inc/agent-plugin02Claude 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.
03Claude 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 ChatCut-Inc/agent-plugin04Codex, 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.
We could not quote an install command from this repo's README. The commands listed here are the generic ones for any skill repository and may not apply, so check the README first.

heygen-com/hyperframes
HeyGen's 21 skills for its open-source HTML-to-video framework: an agent plans, codes and renders explainers, launch videos, captions and music-synced clips as deterministic MP4s.
browser-use/video-use
A skill that lets a coding agent edit raw footage by conversation: it cuts from a word-level transcript, grades color, adds overlay animations and subtitles, then checks its own render.
yikart/AiToEarn
Video-focused SKILL.md files from the AiToEarn content agent, led by a short-drama recap skill that submits clips for AI narration and voice-over; they rely on the platform's own tool calls.
remotion-dev/skills
Remotion's own skill set for coding agents that build videos as React code: project setup, markup rules, captions, live preview and rendering to video or stills.
luoluoluo22/jianying-editor-skill
Lets a coding agent script the desktop JianYing Pro app (CapCut's China edition): import media, add subtitles, TTS voiceover, music, effects and keyframes into an editable draft.
This is a third-party skill. It is not maintained or audited by Pencil0, and skills can run scripts on your machine, so read the SKILL.md and any scripts before installing. Stars, license and dates are a GitHub snapshot and may be out of date.
