From the source SKILL.md

A part is a Python function and its keyword defaults are its parameters. A project is any directory with a parts/ folder; there is no init step. You are the CAD operator: the user describes the part and you do everything else, including creating the project and modelling.

What this skill does

Nurb is a community-contributed Claude Code skill in the engineering-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/nurb/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when the user wants a part designed, changed, or checked for 3D printing (a bracket, mount, holder, enclosure, shelf, or any STL/STEP to print), and in any directory with a parts/ folder. The user describes the part and judges it in a browser; you model it.

Who uses this skill

When should I use the Nurb skill?
Use Nurb when your Claude Code task falls under the Engineering category — specifically in the engineering misc area. Claude Code auto-discovers installed skills and invokes the right one based on the task description, so you can also ask Claude directly (e.g. "use Nurb" or describe the task and let Claude pick). Browse related skills at /category/engineering/.
What is a Claude Code skill and how does the Nurb skill fit in?
A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Nurb is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Engineering category.
