H3 Storyboard

It covers the step before prompt syntax: what a shot must convey, how many beats it can hold, shot length, framing, camera position, expression direction and dialogue handling. Its central finding is that packing many expression beats into one long shot makes H3 flatten them, while several short single-beat shots restore them, and that a dialogue tag helps but takes screen time from neighboring shots. Further rules cover size and distance wording, reference images for shape and identity, 9:16 framing limits, collisions and liquid volumes, and checking results with PSNR. A SOURCES.md file labels every rule; the SKILL.md body is in Traditional Chinese, the README in English, and the notes come from locally run production of a vertical serial drama.

• 01From the README

  The install command quoted from the repository README.

  $ npx skills add https://github.com/phileiny/h3-storyboard-skill --skill h3-storyboardCopy

• 02skills 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 phileiny/h3-storyboard-skillCopy

• 03Claude 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 phileiny/h3-storyboard-skillCopy

• 05Codex, 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.
