Purpose

This post demonstrates how to use the Shopify Expert skill in Claude Code for platform development tasks.

Environment

Claude Code CLI
claude-skills plugin
Shopify development environment

What is Shopify Expert?

The Shopify Expert skill provides specialized knowledge for Shopify platform development. It helps when you’re working on:

Custom theme development
App building and integration
Store setup and configuration
Liquid template customization
Shopify API implementation

When I use this skill, I get access to platform-specific patterns, best practices, and common solutions that Shopify developers encounter.

Installation

First, you need the claude-skills plugin installed. Here’s how I set it up:

# Install the plugin
npm install -g @jeffallan/claude-skills

# Or using Claude Code's built-in skill system
# Navigate to your skills directory
cd ~/.claude/skills

# Add the Shopify Expert skill
git clone https://github.com/jeffallan/claude-skills.git

Then verify the installation:

# List available skills
claude skill list

# You should see shopify-expert in the output

Core Usage Patterns

I trigger the Shopify Expert skill in a few ways:

Direct invocation:

Use shopify-expert to help me build a custom section

Context-based triggers:

I'm working on a Shopify theme and need to create a product slider

Problem-specific requests:

How do I optimize my Shopify store's performance using the Online Store 2.0 architecture?

Example 1: Custom Section Development

When I needed to create a custom product feature section, I used:

Use shopify-expert to create a custom product feature section with image and text blocks

The skill guided me through:

Schema structure definition
Liquid template implementation
CSS styling patterns
JavaScript functionality

Here’s the schema structure it helped me create:

{% schema %}
{
  "name": "Custom Feature",
  "settings": [
    {
      "type": "text",
      "id": "heading",
      "label": "Heading",
      "default": "Feature Section"
    }
  ],
  "blocks": [
    {
      "type": "feature",
      "name": "Feature",
      "settings": [
        {
          "type": "image_picker",
          "id": "image",
          "label": "Image"
        },
        {
          "type": "text",
          "id": "title",
          "label": "Title"
        },
        {
          "type": "textarea",
          "id": "description",
          "label": "Description"
        }
      ]
    }
  ],
  "presets": [
    {
      "name": "Custom Feature",
      "blocks": [
        {
          "type": "feature"
        }
      ]
    }
  ]
}
{% endschema %}

The key point here is that the skill knew the exact schema structure Shopify expects for Online Store 2.0 themes.

Example 2: API Integration Pattern

When I needed to integrate with the Shopify Admin API, I asked:

Use shopify-expert to show me how to fetch product data using the Storefront API in a theme extension

The response included the proper authentication method:

// Storefront API access token from theme settings
const storefrontAccessToken = Shopify.theme_settings.storefront_token;
const shopDomain = Shopify.shop;

async function fetchProductData(handle) {
  const query = `
    query getProduct($handle: String!) {
      productByHandle(handle: $handle) {
        id
        title
        description
        variants(first: 10) {
          edges {
            node {
              id
              price {
                amount
                currencyCode
              }
            }
          }
        }
      }
    }
  `;

  const response = await fetch(
    `https://${shopDomain}/api/2024-01/graphql`,
    {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
        'X-Shopify-Storefront-Access-Token': storefrontAccessToken
      },
      body: JSON.stringify({
        query,
        variables: { handle }
      })
    }
  );

  return response.json();
}

Best Practices

DO

Be specific about your Shopify context

Mention if you’re working on themes, apps, or scripts
Include your Shopify plan (Basic, Shopify, Advanced) when relevant
Specify the theme architecture (Vintage vs Online Store 2.0)

Provide your current setup

I'm using Dawn theme version 12.0 and need to add a mega menu

Ask about limitations

Use shopify-expert to explain Liquid template performance limitations

DON’T

Don’t skip version details

Wrong: “How do I create a section?”
Right: “How do I create a section for Dawn theme 12.0?”

Don’t ignore Shopify Plus features

If you’re on Shopify Plus, mention it - some features are Plus-only
Scripts and bulk operations differ by plan

Don’t forget about Liquid vs React

Be clear if you’re working with traditional Liquid templates or theme app extensions using React

Common Use Cases

Theme Customization

Use shopify-expert to modify the product page template in Dawn theme

Performance Optimization

Use shopify-expert to show me how to lazy load images in my Shopify theme

App Development

Use shopify-expert to guide me through creating a Shopify app using CLI 3

Storefront API

Use shopify-expert to implement cart operations with the Storefront API

The Shopify Expert works well with other skills:

coding-standards: For code quality and structure
javascript-patterns: When working with theme extensions
security-review: For app development and API security

Summary

In this post, I showed how to use the Shopify Expert skill in Claude Code. The key point is that this skill provides specialized knowledge for Shopify development, from theme customization to API integration. When you trigger it with specific context about your Shopify setup, you get targeted solutions that follow platform best practices.
