SC 01Overview

What it does

The agent first inspects the operating system and GPU, then selects one of two validated component sets (one for low-VRAM cards of about 8 GB, one for 16 GB cards) and runs a read-only planner and preflight check before generating. For a clip it chooses a mode (text-to-video, first frame, first and last frame, or reference-to-video, which is still experimental), builds an anchor sheet for characters and shots, submits a ComfyUI workflow and checks the output with ffprobe. Bundled notes cover cinematic prompting, multi-segment sequences joined with ffmpeg, and face quality. Only Windows with an NVIDIA GPU is validated, and the model packages are large downloads, with the preferred copies hosted on Baidu Netdisk.

SC 02Install

How to install it

  • 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 Rimagination/h3lite
  • 02Claude 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 Rimagination/h3lite
  • 04Codex, 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.
