Step 0: Start with one prompt

Claude chose what to make and wrote this prompt, with the Rainbrand MCP connected.

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.

Step 1: Add a brand

Step 2: Ask for Briefs

Claude asked for 2 Briefs first: one for the photo, one for the counter pieces.

For the aubergine bao photo

Claude asked for

rainbrand · create_brief

task: “Make one photograph of Yumbun's Aubergine bao for two menu pieces at its food-hall counters (Old Spitalfields Market and Kerb's Seven Dials Market): a 16:9 menu screen over the counter and a phone menu. The current menu describes it as katsu aubergine, Szechuan chilli bean sauce, cucumber and spring onion in a soft steamed bun; it is vegan and dairy-free. The Brand Library has photos of the pork, chicken and tofu bao but none of the aubergine, so this photo must sit beside those existing product shots as part of the same set: one folded bao on a plate, matching their styling, set, light and framing. No text, logos, hands or packaging in the image.”

Yumbun food-photo context

Brand: “Yumbun is a London street-food brand serving fresh steamed bao with playful, Japanese izakaya-inspired East–West fusion.”
Photo style: “One open/folded bao as the hero on an off-white ceramic plate; a close three-quarter view; a simple set; bright, directional light with crisp shadows.”
Unknowns: “The supplied Brand Library has no aubergine-bao photo” and the set to extend is unresolved.

For the counter pieces

Claude asked for

rainbrand · create_brief

task: “Design three related pieces that explain Yumbun's menu at its two food-hall counters, Old Spitalfields Market and Kerb's Seven Dials Market. The menu names each bao in kanji beside its English name: 茄子 Aubergine, 鶏肉 Chicken, 豆腐 Tofu, 豚肉 Pork, and 定食 for the Bun Box set. Most customers can't read them, so the pieces decode them in Yumbun's voice. (1) A 20-second 16:9 looping menu video for the screens above the Seven Dials counter: each bao enters as its kanji, which resolves to the English name, fillings, diet tags and price, ending on the logo. (2) A printable A3 landscape tray liner, 'read your bao': the kanji decoder with each bao's photo, the diet key, a one-line origin story and a QR code to the phone menu. (3) The phone menu page that QR code opens, where tapping a kanji tile reveals that bao, with a switch between the two halls' prices. Use the real current menu: Aubergine (katsu aubergine, Szechuan chilli bean sauce, cucumber, spring onion; VG, DF), Chicken (Japanese-style fried chicken, pickles, mayo, lettuce, chilli; DF), Tofu (crispy aromatic tofu, black bean mayonnaise, garlic choy sum, chilli pickles; VG, V), Pork (slowly roasted pork belly, cucumber, spring onion, hoi sin sauce; DF), Bun Box (2 buns of choice, 2 crispy veg gyoza, seasonal 'slaw; £12.50). Bao cost £6 or 2 for £11.50 at Seven Dials and £5.50 or 2 for £10.50 at Old Spitalfields.”

Step 3: Make the menu pieces

Yumbun’s menu names each of its steamed buns in Japanese characters. Concepts by Claude; the menu comes from yumbun.com (opens in a new tab), and the readings, meanings and jokes are Claude’s.
