feicaiclub/video-spec-builder
Interviews you about a video idea until it becomes a timed, shot-by-shot video-spec.md that the HyperFrames skill can render; it also edits an existing spec and checks changes for conflicts.
Starts from a loose idea for a promo, product demo, short animation or social clip and asks about audience, platform, length and the one message to leave behind, pushing back on vague adjectives until you describe actual shots. It tells you which rendering features exist (voice-over, caption styles, music-synced motion, visual themes) and writes a video-spec.md with a timed shot table, using bundled pacing rules, question banks and a component catalog. If a spec already exists it switches to an edit mode and checks each change against the other shots. It does not produce footage; rendering is a separate step in the HyperFrames skill, which you install alongside it.
01From the README
The install command quoted from the repository README.
npx skills add feicaiclub/video-spec-builder02Claude 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 feicaiclub/video-spec-builder04Codex, 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.
