Claude Code and Codex
npx skills add cloudai-x/threejs-skillsNotes
Targets three.js r186. The README documents Claude Code: npx skills add cloudai-x/threejs-skills, or a copy into ~/.claude/skills or .claude/skills. The installer offers the whole pack, not this skill alone. You need a browser or app runtime to see the scene. No paid API or desktop modeler is listed.
