prototype: Claude Code skill

What it does

Builds a throwaway prototype, of the logic or of a UI, to answer one design question.

The description Claude matches your request against: Build a throwaway prototype to answer a design question. Use when the user wants to sanity-check whether a state model or logic feels right, or explore what a UI should look like.

When to use it

You can't decide how something should behave or look until you see it. Wayfinder uses it too.

How to start it

Automatic, or /prototype

Claude loads it by itself when your request matches, so you rarely need the command. The suggester plugin also points it out when it fits.

Install

prototype is part of the planning plugin. Install just that plugin in Claude Code:

/plugin marketplace add iatee/claude-skills
/plugin install planning@iatee-skills
/reload-plugins

Or install the whole collection:

/plugin marketplace add iatee/claude-skills
/plugin install all@iatee-skills
/reload-plugins

New to this? Using skills explains what a skill is and how installing works.
