(Example) Claude 4 outputs

# Claude with Rainbrand for [Yumbun](https://yumbun.com/).

## The test

We asked Claude to make something useful for Yumbun. It chose to explain the Japanese characters on its bun menu and wrote the prompt below.

## The setup

Claude could use the [Rainbrand MCP](https://docs.rainbrand.com/mcp/connect), with Yumbun’s brand added from [yumbun.com](https://yumbun.com/).

## Prompt

Use Rainbrand and Yumbun’s brand to make something useful for its food-hall counters: decode the kanji names on its bao menu. Make a photo of the aubergine bao (its brand library has none), a 20-second counter-screen menu loop, an A3 tray liner and the phone menu the liner’s QR code opens. Use the real menu.

## How Claude made it

From Yumbun’s brand to four pieces for its counters, each reviewed twice.

1. Brand
2. Brief
3. Outputs
4. Review

## Brand

[Read the docs](https://docs.rainbrand.com/guides/create-brand)

Rainbrand turns a brand’s identity, guidance and files into shared context that agents can use. Yumbun’s brand was added from [yumbun.com](https://yumbun.com/).

## Brief

[Read the docs](https://docs.rainbrand.com/guides/request-brief)

A Brief is focused brand guidance and files for one task. Claude requested one for the photo and one for the counter pieces.

## Outputs

[View more examples](https://www.rainbrand.com/examples/)

Yumbun sells filled steamed buns at two London food markets, and its menu names each one in Japanese characters. These four pieces explain them. The menu comes from [yumbun.com](https://yumbun.com/); the readings, meanings and jokes are Claude’s.
