Step 0: Start with one prompt

One message to Claude, with the Rainbrand MCP connected and Eager’s brand already added.

Guidance

“Write like a friendly, matter-of-fact juice person: direct, lightly irreverent, and unpretentious.”

Claude asked for one Brief first, covering the whole campaign.

task: “Coordinated launch campaign for a HYPOTHETICAL new Eager flavour, made as an independent concept (not an Eager release). Do not treat the flavour as a real product or write it into the brand.

Concept: EAGER Blackcurrant Juice Drink, the eighth flavour joining the current seven (Apple, Orange, Pineapple, Pink Grapefruit, Tomato, Cranberry, Pomegranate). Carton name "BLACKCURRANTS", carton descriptor "ALREADY SQUASHED BLACKCURRANT JUICE DRINK". Packaging follows the existing 1L carton system exactly (solid-colour carton, white screw cap, large P22 Mackinac Pro serif fruit name, vertical EAGER wordmark, small descriptor) in a new deep blackcurrant purple with lilac lettering. Campaign line: "NOW IN PURPLE." Supporting line: "Seven flavours was fine. Eight is also fine." Joke: British people know blackcurrant as squash they dilute themselves; this one is already at drinking strength. Audience: UK customers who buy juice by the box. Real claims only: store unopened at room temperature, refrigerate after opening; contains fruit and therefore sugar, drink responsibly. No ingredient, health, price, availability or endorsement claims for the concept flavour.

Deliverables, all sharing one story:

  1. Responsive HTML launch page (desktop + mobile) with real brand fonts, logo, generated campaign imagery, product story and a demonstration CTA.
  2. Two or three new campaign images generated with GPT Image 2.5 Sunburst: a studio product hero of the purple carton matching Eager's flat-lay carton photography, an eight-carton lineup with the purple carton added to the existing range, and a lifestyle/use scene (cupboard storage or pouring).
  3. Five-slide 1080x1350 Instagram carousel: hook, reveal, product detail, use, closing CTA.
  4. 12-second 9:16 product reel generated with Seedance 2.5 using the campaign images as references, with sound.
  5. About 20-second 1920x1080 landscape launch film built in HTML (HyperFrames) with brand typography, logo, generated visuals and motion.
