Here’s exactly how to set up your Stylus theme — using Patch Pickleball and the Axiom theme as the worked example.
Before you start
Claude Pro
$20/mo from Anthropic — you need this for Claude Projects.
Your SKILL.md file
Comes in the Stylus pack download immediately after purchase.
Your brand colors
Hex codes are best. Named colors work too — Claude will interpret them.
Your logo URL
A direct link to your logo image. Squarespace, Cloudinary, your CDN — any public URL.
Create a Claude Project
Go to claude.ai and click Projects in the sidebar. Create a new project — name it something like "Patch Pickleball Emails".
Claude Projects persist across conversations. Every chat inside the project has access to the files you upload — including your SKILL.md.
Requires
Claude Pro ($20/mo). Projects are a Pro feature — the free tier does not include them.
Upload your SKILL.md
Inside your new project, open Project knowledge and upload your SKILL.md file. Claude reads this once and remembers it for every conversation in the project.
Your pack includes one SKILL.md matched to your theme — Pitch, Grove, or Axiom. Upload the right one.
Send your first message
Start a new chat in the project. Your first message sets up the brand — colors, logo, and logo shape. Include all four things in one message so Claude can confirm before building.
Your product or company name
Your brand colors — hex codes preferred, or color names
Your logo URL — a direct link to the image file
Whether the logo is a horizontal wordmark or a square icon mark

Example — Patch Pickleball
Colors: navy #1B2A4A and gold #D4AF37.
Logo: https://images.squarespace-cdn.com/...Icon-yellow.png
It’s a square icon mark, not a wordmark.
Gold ( #D4AF37) is the brighter of the two, so it becomes the accent. Navy (#1B2A4A) is darker, so it becomes the callout background — used in featured highlight blocks throughout the email.
Describe what you need
Now ask for an email in plain English. No code required. Claude returns a complete, production-ready HTML file — styled to your brand, using the component library from the skill.
Describe layout, content, and intent in plain English — Claude maps it to the component library automatically.
Claude outputs the full HTML. Paste it into the custom HTML block in Mailchimp, Klaviyo, or any other ESP. Swap the image placeholder for a real photo. Done.
Revisions are one sentence
"Make the headline bolder." · "Add a second CTA at the bottom." · "Change the date to June 20." Claude updates the HTML in place — every output is still exactly on-brand.
The result
The Courts Are Officially Open — Patch Pickleball
