Prototype App

Category: Product  ·  Sub-category: design-system-ui  ·  Last updated:
Build the frontend vertical of a feature inside the real app (routes, pages, components, remote functions) backed by an in-memory mock namespace — without touching packages/core or any backend package. Use after a /prototype is validated, when the user wants the feature clickable in the actual app before core exists.

From the source SKILL.md

Build a feature's frontend vertical in the real dashboard, with the data layer faked by an in-memory mock namespace shaped exactly like the core slice will be. The app runs the feature for real — real routes, real layout, real components, real remote functions — but nothing below the api seam exists yet.

What this skill does

Prototype App is a community-contributed Claude Code skill in the design-system-ui sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/prototype-app/ and loads when your prompt matches the skill's trigger.

Who uses this skill

The Prototype App Claude Code skill is built for product managers, product designers, and cross-functional teams planning, shipping, and measuring product features. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 186,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

Browse related skills at /category/product/.
What is a Claude Code skill and how does the Prototype App 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. Prototype App is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Product category.
