Step 0: Start with one prompt

We asked Codex to help someone choose a Son of a Tailor T-shirt, then care for it. It wrote this prompt, with the Rainbrand MCP connected.

Use Son of a Tailor’s brand to make two useful pieces for its Cotton T-Shirt: a responsive editorial guide to choosing between 150 and 200 g/m², and a two-sided A6 care insert to keep after delivery. Use its real imagery, material facts, typography and understated voice. Label both as independent concepts. Request focused Briefs, then review every rendered asset twice and save the evidence.

Step 1: Add a brand

Codex added Son of a Tailor to Rainbrand from sonofatailor.com (opens in a new tab). A sample of what it could use:

Step 2: Ask for Briefs

Codex asked for 2 Briefs first: one for the cotton guide, one for the care insert.

For the cotton guide

Codex asked for

rainbrand · create_brief

task: “Create an independent responsive editorial page concept titled ‘A T-Shirt, considered.’ for Son of a Tailor’s existing Cotton T-Shirt. Help a first-time shopper understand medium 150 g/m² versus heavy 200 g/m² Supima cotton, drape and white transparency, then explain custom sizing and 24 pre-engineered sizes. Use calm informed copy, restrained neutral layout, exact supplied fonts and the actual SON icon. The white T-shirt on a wooden peg is an illustrative cotton image, not a side-by-side proof of the two weights. Product facts must match https://www.sonofatailor.com/product/cotton-t-shirt; no new products, prices, discounts, invented fit prediction, or unsourced environmental claims. Supply relevant guidance and selected imagery, typography and logo files. This is a digital editorial concept for prospective buyers, captured for a public Rainbrand example.”

Codex asked for

rainbrand · create_brief

task: “Create an independent two-sided A6 parcel insert concept titled ‘Care, kept close.’ specifically for Son of a Tailor’s Cotton T-Shirt. Audience: a customer who has received the garment. Goal: a useful card to keep with product-specific care, encouraging long use. Front: real hanging white T-shirt photograph, actual SON icon, quiet title and a short note. Back: gentle machine wash at 40°C/100°F with mild detergent; separate light and dark colors; no fabric softener; air dry, no tumble drying; iron lightly. Verify wording against https://www.sonofatailor.com/product/cotton-t-shirt. Do not generalize cotton care to wool, cashmere or other garments. Do not invent warranties or environmental savings. Use exact supplied fonts and neutral palette. Public exports will be captures and an image-based PDF. Select focused brand guidance, logo, typography and imagery.”
